Description

PANM (personal area network) server, method and system for identifying PNE (personal network entity) in PAN (personal area network) and PNE

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a Personal Area Network Management (PANM) server, a method and a system for identifying a personal area network component (PNE) in a Personal Area Network (PAN), and a PNE.

Background

The third generation mobile communication standardization partnership project (3GPP) introduced a Personal Network Management (PNM) service in its R7 version, which proposes a concept of Personal Network Management (PNM) for managing a Personal Network (PN) composed of a plurality of terminal devices in a future network in a scenario where a user may own the terminal devices. The PNM mainly focuses on management of User Equipment (UE) belonging to the same user, such as how the UE joins in a PN, how to activate redirection configuration of different layers for the UE, and setting access rights of the UE. Further, the 3GPP extends the management concept of PN to user components physically separated from the User Equipment (UE) or to Mobile Equipment (ME) and Terminal Equipment (TE) attached to the UE. Referring to fig. 1, fig. 1 is a diagram of a conventional PNM service architecture. In fig. 1, a PN may be composed of one or more PANs, and each PAN is composed of a UE and a group of TE/MEs belonging to the same user as the UE, so that the UE, ME or TE in the PN may be referred to as PNE, which is referred to as PAN management PANM. The PANM is the management of PNEs within the PAN. Neither the ME nor the TE have Universal Mobile Telecommunications System (UMTS) subscriber identity module (USIM) cards. Generally, the ME may be a UE external device with wireless access capability, such as a remaining part of the mobile phone with the USIM card removed from the mobile phone; while TE is typically an external device of the UE, such as a display, that does not have radio access capability.

In PNM, in order to identify different UEs sharing a common user Identity (IMPU) at call routing control, the following two technical solutions are adopted:

1. globally routable user agent uniform resource management identifier (GRUU) technique

Referring to fig. 2, fig. 2 is a schematic diagram of a conventional terminal identified by using GRUU technology. In order to prevent forking (forking) of a REQUEST message of an initial session protocol (SIP) to a plurality of UEs in case that the plurality of UEs share an IMPU while making a call, IETF and 3GPP introduced the concept of GRUU. The GRUU is a combination of the IMPU and the resource name of the UE, such as the instance id. The Instance ID is an ID used to identify the UE Instance, and thus, the GRUU can uniquely identify one UE. Even if an IMPU is shared by multiple UEs, using a GRUU as a REQUEST URI can still ensure that SIP messages are sent to a uniquely specified UE.

2. Feature tag (feature tag) technique of IETF

Feature tag is an application mechanism added by IETF on SIP signaling, and is used to add various parameters behind the contact header field of SIP signaling to indicate various application capabilities of the terminal, such as audio capability, video capability, mobility capability, supported languages, supported SIP methods, priority, and the like. For the featuretag technology, RFC 3840 can be referred to. The IETF also proposes a "Caller Preferences" mechanism in RFC 3841, which combines with feature tag, and allows the Caller to carry the application capability and feature that the called terminal should or should not have as a connection in the Accept-Contact or Reject-Contact header field according to the attributes of the session, so that the network can search the most suitable UE among the called UEs according to the specified application capability for connection.

The above prior art scheme can correctly identify the UE according to the actual situation in the PNM service, and continue the service to the UE. However, no specific solution is provided in the industry as to how to correctly identify the PNE in the PAN and accurately connect the service to the PNE when handling the called party.

Referring to fig. 11, fig. 11 is a schematic structural diagram of a UE in an embodiment of the present invention, where the UE may include:

a storage module, configured to store identification information of the UE;

and the sending module is used for sending the identification information of the UE.

The first embodiment is as follows:

in this embodiment, a feature tag parameter for identifying a PNE is added in a contact header field of an SIP signaling, and the newly added feature tag parameter is used to identify a PNE such as an ME or a TE that shares a USIM/ISIM with a UE. And setting the name of the newly added feature tag parameter as termindicate.

In this embodiment, the PNE is an ME with wireless access capability. After the PANM server can identify the ME, namely after the ME joins the PAN, the PANM server performs call routing control on the redirection service in the PAN of the ME. Referring to fig. 12, fig. 12 is a flowchart illustrating a process of identifying PNEs in a PAN according to an embodiment of the present invention. The process comprises the following steps:

step 1201, the UE initiates an IMS registration request in the PAN, and the registration request message is sent to the S-CSCF.

In this step 1201, the registration request may be a REGISTER message of the SIP in fig. 12. The registration request carries information such as a contact _1 address, an IMPU, and reg-id of the UE, and a contact header field of the registration request is followed by a terminate parameter indicated by an identity terminal, and the parameter is assigned as identity information of the UE, such as instance id of the UE. Among them, the so-called contact address is an address available for routing. The contact _1 address described above is an address that can be used to address to the UE.

Step 1202, after the UE completes the registration in the S-CSCF, the S-CSCF notifies the pancm server of the UE registration event package. The registration event packet contains the contact header field content of the terminal parameter of the instance id of the UE.

In this step 1202, it is assumed that the PANM server has previously subscribed to the registration event package of the user with the S-CSCF, so here the S-CSCF can notify the PANM server. As shown in fig. 12, the S-CSCF may NOTIFY the aforementioned registration event package to the pancm server using a NOTIFY message of SIP.

Step 1203, the ME belonging to the same user as the UE initiates an IMS registration request, and the registration request message is sent to the S-CSCF.

The UE and the ME share the same USIM/ISIM card.

In this step 1203, the registration request may be a REGISTER message of SIP in fig. 12, the registration request carries the contact _2 address, the IMPU desired to be shared with the UE, the reg-id of the ME, and so on, and the registration request carries the terminate parameter indicated by the identifier PNE terminal, which is assigned as the instance id of the ME, i.e. the information for identifying the PNE is carried by the terminate parameter.

It should be noted that, in the registration request message received by the S-CSCF from the UE or the ME, different reg-ids are carried, where the reg-id is a SIP signaling parameter introduced in an outbend mechanism in the existing IETF, and the parameter is used in a contact header field, and the design purpose of the parameter is to indicate multiple registration events initiated by the same terminal through different contact addresses, so that the S-CSCF can maintain multiple registration states of the same terminal, that is, the reg-ids can be used to distinguish multiple registrations of the UE and the ME sharing the USIM/ISIM for the network. But this parameter is only present in the registration signalling and not in the call signalling of the call, i.e. it cannot be used as a routing flag. In the embodiment of the present invention, the S-CSCF may also determine, according to the termindicate parameter provided in the embodiment of the present invention, a multiple registration event between terminals sharing a USIM/ISIM in the same PAN of the registration event in this step.

In addition, the registration request of the ME may also be sent to the network side by the UE instead of the ME, that is, the UE in the PAN performs messaging with the network.

Similar to the contact _1 address, the above-described contact _2 address may also be a reachable IP address of the PNE terminal.

Step 1204, S-CSCF sends registration event package of ME to PNM server. The registration event package contains the contact header field content of the terminate parameter of the instance id of the ME.

In this step, the S-CSCF may NOTIFY the aforementioned registration event package to the pancm server using a NOTIFY message of SIP. And the S-CSCF accepts the registration request of the ME, namely the registration of the ME on the S-CSCF is successful. In the embodiment of the invention, after the registration of the ME in the S-CSCF is successful, the PANM server acquires the received registration event packet through the S-CSCF and acquires the information for identifying the PNE, namely the ME is used as a terminal with wireless access capability and can be identified by the PANM server at the network side.

Step 1205, the ME interacts with the PAN server through the Ut interface to complete the process of adding the ME to the PAN and activating the service, and the PAN server obtains the identification information of the ME by adding the ME to the PAN, where the identification information is also the instance id of the ME.

In step 1205, in the process of adding ME to PAN, the PANM server receives a request for adding ME to PAN, where the request may be sent by ME to the PANM server; or, the ME sends the PANM server through the UE; or, the UE sends the information directly to the PANM server.

The PANM server associates the identification information of the ME in the PAN, which is carried in the received request for requiring the ME to join the PAN, with the information for identifying the ME, which is acquired from the registration event packet sent by the S-CSCF, so as to identify the ME in the PAN. After the association, the PANM server may know that the ME identified by the information for identifying the ME, which is originally obtained from the registration event packet, is added to the PAN, and therefore, the ME should be a terminal in the PAN that shares the same USIM/ISIM card with the UE, and identify the ME in the PAN according to the fact that the identification information of the ME is different from the identification information of the UE. In this embodiment, the ME is only used as an example, and for PNE, the specific associated method may be: and binding the identification information of the PNE in the PAN carried in the received request with the identification information of the PNE contained in a feature tag type parameter terminal added after a contact header field which is acquired from a registration event packet and is related to the identification information of the PNE.

In addition, in this embodiment, it is assumed that the UE has been previously added to the PN.

Step 1206 the calling party initiates a call, the call signaling of which is sent to the S-CSCF.

In this step 1206, when a call needs to be connected to the terminal equipment of the called user, the call is first sent to the S-CSCF. As shown in fig. 12, the call signaling initiated by the calling party may be an INVITE message of SIP.

Step 1207, the S-CSCF triggers the call signaling to the PANM server according to the initial filter rules (iFC).

Step 1208, the PANM server performs connection configuration on the redirection service of the PNE in the PAN, selects the ME to connect the call according to the redirection policy, fills the feature tag type parameter content of the Accept-Contact header field of the INVITE message as the instance id of the terminating-match-ME, and returns the INVITE message containing the Accept-Contact header field, that is, carrying the identification information of the ME in the PAN, to the S-CSCF.

For PNE, the redirection policy may include: redirection priority settings of the PNE, and/or caller preference information, and/or media attributes, and/or media component information, and/or operator policy.

If there are multiple media components in the call signaling of the call, such as video and audio components, etc., then if a redirection policy is needed, the PNM server needs to split multiple different media components in the call signaling according to the redirection policy before continuing the call signaling, and perform terminal device and access mode selection on each split multiple media streams, that is, determine that one or more media streams in multiple media streams split from the call session message need to be continued to the PNE according to media component information and/or redirection priority setting of the PNE, etc., for example, reach an audio media stream to a specified ME, and send a video media stream to a specified TE, etc.

Step 1209, the S-CSCF receives the INVITE message, locates the registration connection of the instance id of the terminal dicate — ME according to the ME identifier information carried in the message, that is, fills the Request-URI in the INVITE message as the contact _2 address according to the ME identifier information, and issues the INVITE message.

In this embodiment, an instance id of an ME can uniquely identify a terminal device, and then the S-CSCF uses the contact _2 address, so that a call can be accurately terminated to a specified ME.

The

above steps

1208 and 1209 are that the pancam server selects the PNE to continue the call according to the redirection policy after receiving the call initiated by the calling party; and indicating the S-CSCF to perform routing control by using the identification information of the PNE so as to connect the call to the specific implementation of the PNE.

Step 1210, the ME receives the call and returns a final response of the call, and the process of identifying the PNE is finished.

It should be noted that, in the first embodiment, taking an ME with a wireless access capability as an example, a scheme for identifying an ME in a PAN by using identification information of the ME is described. For TE without radio access capability, it does not have the capability of actively registering with the network side, and there is no IMS registration procedure. The PANM server acquires the identification information of the TE in the PAN in the process that the UE actively requests to add the TE into the PAN so as to identify that the TE is the terminal in the PAN. The identification information of the TE may be an identifier derived from the UE identity, such as the UE identity plus a suffix, which may be a random number, or the like, or a resource name of the TE, such as an instance id of the TE, and may also be carried by a terminate parameter. The term parameter containing the identification information of the TE may be a term parameter containing the identification information of the TE, which is carried in a contact header field of a request sent by the UE to request the TE to join the PAN, to inform the PNM server in the process of adding the TE to the PAN.

And when continuing the call, the PANM server sends a call signaling to the S-CSCF to carry the instance id of the UE in the PAN where the TE is located, and the instance id of the UE indicates the S-CSCF to carry out call routing control. However, the call signaling issued by the S-CSCF needs to carry the terminate parameter containing the identification information of the TE, and after the call signaling reaches the UE in the PAN, the UE identifies the TE in the PAN according to the terminate parameter.

In the first embodiment, the PNE joins the PAN through the PAN server, so that the PAN server can identify the PNE in the PAN that belongs to the same user as the UE, and thus, the user can make full use of terminals or terminal peripherals with different capabilities to obtain better service experience.

Example two:

referring to fig. 13, fig. 13 is a flowchart of identifying PNE in the second embodiment of the present invention. In this embodiment, the PNE is identified by GRUU technology, and is assumed to be an ME with wireless access capability. After the PANM server can identify the ME, namely after the ME joins the PAN, the PANM server performs call routing control on the redirection service in the PAN of the ME. The process comprises the following steps:

step 1301, the UE in the PAN initiates an IMS registration request, which is sent to the S-CSCF.

In this step 1301, the registration request may be a REGISTER message of the SIP in fig. 11. In this step, an + sip. instance parameter may be directly added to the contact header field of the registration request, and the instance id _1 of the UE may be uniquely identified by the content of the + sip. instance parameter. The registration request further carries information such as the reg-id of the IMPU and the UE.

Step 1302, the S-CSCF generates GRUU _1 according to the value of instance id _1 in the IMPU and contact header fields of the UE, and notifies the register event packet of the UE to the PANM server.

The registration event packet includes a contact header field content of the registration request of the UE, and the contact header field content includes GRUU _ 1. As shown in fig. 11, the S-CSCF may NOTIFY the aforementioned registration event package to the pancm server using a NOTIFY message of SIP.

In this embodiment, it is assumed that the PANM server has previously subscribed to the S-CSCF for the registration event of the user, so the S-CSCF may notify the PANM server.

Step 1303, the ME belonging to the same user as the UE initiates an IMS registration request, which is sent to the S-CSCF.

In this step 1303, the registration request may be a REGISTER message of the SIP in fig. 11. In this step, an + sip. instance parameter may be added to the contact header field of the registration request, and the content of the + sip. instance parameter is an instance id _2 that can uniquely identify the ME, that is, information for identifying the ME. The registration request further carries information such as IMPU and reg-id of ME which the UE wants to share.

The S-CSCF also carries different reg-ids in the registration request message of the UE and the ME, and the S-CSCF senses that the registration event of the ME is multi-registration initiated by the ME sharing the same USIM/ISIM with the UE according to the different reg-ids, and does not log out the connection of the original contact _ 1. The S-CSCF can also judge that the registration event of the ME is a multi-registration event between terminals sharing the USIM/ISIM according to different instance ids.

The registration request of the ME may also be sent to the network side by the UE instead of the ME.

Step 1304, the S-CSCF informs the PANM server of the ME registration event package. The registration event package contains GRUU _2 allocated by the S-CSCF to the ME.

In this step 1304, the S-CSCF may NOTIFY the PANM server of the registration event package using a NOTIFY message of SIP. And the S-CSCF accepts the registration request of the ME, namely the registration of the ME on the S-CSCF is successful. In the embodiment of the invention, after the registration of the ME in the S-CSCF is successful, the PANM server acquires the received registration event packet through the S-CSCF and acquires the information for identifying the PNE, namely the ME is taken as a terminal with wireless access capability and can be identified by the PANM server on the network side at the moment, but at the moment, the ME is not added into the PAN where the corresponding UE is located through the PANM server, so that the PANM server does not identify whether the ME is the PNE in the PAN.

Step 1305, the ME interacts with the PANM server through the Ut interface to complete the process of adding the ME to the PAN and activating the service. The PANM server joins the PAN through the ME, acquires the identification information of the ME in the PAN, wherein the identification information is GRUU _ 2.

In step 1305, in the process of adding ME to PAN, the PANM server receives a request for adding ME to PAN, where the request may be sent from ME to PANM server; or, the ME sends the PANM server through the UE; or, the UE sends the information directly to the PANM server.

Step 1306, the calling party initiates a call, the call signaling of which is sent to the S-CSCF.

In this step 1306, when a call needs to be connected to the terminal equipment of the called user, the call is first sent to the S-CSCF. As shown in fig. 11, the call initiated by the calling party may be an INVITE message of SIP.

Step 1307, the S-CSCF triggers the call signaling to the PANM server according to iFC.

Step 1308, the PANM server selects the ME which needs to connect the call, fills in the Request-URI header field content of the INVITE Request as GRUU _2, and returns the INVITE Request containing the contact header field content to the S-CSCF.

In practical application, if the PANM server selects the UE to continue the call signaling according to the redirection strategy, the Request-URI header field content can be filled as GRUU _ 1.

If there are multiple media components in the call signaling, the descriptions of splitting and proceeding of media streams can be found in the description of the similar situation that may occur in step 1208.

Step 1309, the S-CSCF locates the registration connection of GRUU _2 according to the selection of the PANM server, that is, the S-CSCF fills the Request-URI in the INVITE Request as the contact _2 address, and issues the INVITE Request.

In this embodiment, one terminal device can be uniquely identified by the GRUU _2 included in the contact _2, so that the call can be accurately terminated to the specified ME.

Step 1308 and step 1309 are that after the PANM server receives the call initiated by the calling party, it selects the PNE to continue the call according to the redirection policy; and indicating the S-CSCF to perform routing control by using the identification information of the PNE so as to connect the call to the specific implementation of the PNE. It should be noted that, in the first embodiment, the route indication module indicates the route by using the terminate parameter carrying the instance id of the identification information ME of the PNE, and in the second embodiment, the route indication module indicates the route by using GRUU _2 of the PNE.

Step 1310, the UE receives the call, returns a final response of the call, and ends the process of identifying the PNE.

In the first embodiment, an ME with wireless access capability is taken as an example, and a scheme for identifying an ME in a PAN by using identification information of the ME is described. For TE without radio access capability, it does not have the capability of actively registering with the network side, and there is no IMS registration procedure. The PANM server acquires the identification information of the TE in the process of actively requesting to add the TE into the PAN by the UE for identifying the TE in the PAN, so as to identify the TE as a terminal in the PAN. The identification information of the TE may be the identity of the UE suffixed or the instance id of the TE, and may also be carried by the terminate parameter. The term parameter containing the identification information of the TE may be a term parameter containing the identification information of the TE, which is carried in a contact header field of a request sent by the UE to request the TE to join the PAN, to inform the PNM server in the process of adding the TE to the PAN. And when continuing the call, the PANM server sends a call signaling to the S-CSCF to carry the instance id of the UE in the PAN where the TE is located, and the instance id of the UE indicates the S-CSCF to carry out call routing control. However, the call signaling sent by the S-CSCF needs to carry the terminate parameter containing the identification information of the TE, and after the call signaling reaches the PAN, the UE identifies the TE in the PAN according to the terminate parameter.

In the second embodiment, the PNE joins the PAN through the PAN server, so that the PAN server can identify the PNE in the PAN that belongs to the same user as the UE, and thus, the user can make full use of terminals or terminal peripherals with different capabilities to obtain better service experience.

In the above step 1205 and step 1305, the ME activates the service, that is, the PANM server activates and configures the redirection service of the PNE in the PAN according to the identification information of the PNE. Referring to fig. 14, fig. 14 is another schematic structural diagram of the service configuration module shown in fig. 4 in the embodiment of the present invention, including: a configuration request receiving module and a redirection service activation configuration module; wherein,

a configuration request receiving module, configured to receive a redirection activation configuration request of the PNE;

and the redirection service activation configuration module is used for carrying out activation configuration on the redirection service of the PNE according to the identification information of the PNE carried in the configuration request.

The redirection service activation configuration module may include: the device comprises an identification association module and a priority setting module; wherein,

an identifier association module, configured to associate the identifier information of the PNE carried in the redirect activation configuration request with the identifier information of the PNE obtained by the pancam server, and transmit a successful association result to the priority setting module;

and the priority setting module is used for setting the redirection priority of the PNE by utilizing the redirection priority setting information carried in the redirection activation configuration request and the received association success result.

Referring to fig. 15, fig. 15 is a flowchart of performing activation configuration on redirection service of the PNE in the embodiment of the present invention. In this embodiment, a PANM server and a PNM server are combined. The flow shown in fig. 15 includes the following steps:

step 1501, the PNE actively initiates a redirection activation configuration request to the UE, where the configuration request carries identification information of the PNE, redirection priority setting information, a default name, and the like.

The redirection priority setting information may be: information required to connect all calls, designated calls or designated media components in calls to the PNE, such as an activation parameter, optionally including a priority parameter. The activation parameters refer to activation type, service code, and media component identifier, and are used to indicate three different levels of activation and required parameters, and the specific implementation may refer to the activation parameters when the UE is activated.

Step 1502, the UE notifies the user of the configuration request, the user determines whether to allow the PNE to perform corresponding activation, and the user performs subsequent steps in sequence after agreeing, otherwise, returns a failure response to the activation configuration directly.

This step 1502 is an optional step, i.e., the user may be defaulted to agree to activation of the PNE; the manner of notification may take the form of a Graphical User Interface (GUI).

Step 1503, the UE inserts corresponding data according to the mapping relationship of the locally stored PNE, and forwards the activation request to the pancam server. The corresponding data inserted by the UE may include an IMPU, an instance id of the UE, an activation parameter, and optionally a priority parameter.

Step 1504, the Network Application Function (NAF) forwards the configuration request to the PANM server, joining the IMPI of the UE. And the PANM server judges whether the PNE is added into the PAN according to the record saved on the PNM server, if so, the subsequent steps are sequentially executed, and otherwise, an activation failure response is directly returned.

In this step, the pancm server queries a relevant record in the PNM server by using the identification information instance id of the PNE, the IMPU, the IMPI, and the corresponding relationship therebetween, that is, associates the identification information of the PNE carried in the redirect activation configuration request with the identification information of the PNE known by the pancm server, and if the association is successful, it may be determined that the PNE has been added to the PAN, and the subsequent steps are continuously performed.

Step 1505, the PANM server queries the Home Subscriber Server (HSS) for all subscription service information of the IMPU carried in the activation request.

In this step 1505, the subscription of the IMPU of the UE may be taken as subscription information for the entire PAN.

Step 1506, the HSS returns the service codes of all signed services of the IMPU in the response, and the PANM server needs to store the information returned by the HSS.

Step 1507, the PANM server inquires the capability information of the PNE from the capability Entity (capability Entity) for saving the UE capability.

Step 1508, the capability entity storing the UE capability information returns the capability information of PNE to the pancam server.

The capability entity may be a Device Management (DM) server, an S-CSCF, the UE itself or a pancm/PNM server. If the PANM server can directly obtain the capability information of the PNE, steps 1507 and 1308 may not be required. The capability information may be reported to the capability entity by the UE, PNE or PANM server.

Step 1509, PANM server authenticates the activation configuration request, compares the service code to be activated with the service code signed by user, and gets the intersection of the two, if the intersection is empty, it returns the activation failure response directly, otherwise, compares the PNE ability with the needed one to realize the service, when the PNE ability can meet the service requirement, it judges that the service can be activated. The pancm server needs to record the activation setting information of the service and may also override the previous activation configuration.

The foregoing steps 1505 to 1509 are specific implementations in which the pancm server performs redirection priority setting on the PNE by using the redirection priority setting information carried in the redirection activation configuration request and the received association result.

Step 1510, the pamm or PNM server sends a request for setting the implicit subscription identity to the IMPU to the HSS, where the request carries an address of the PNM server, and when the service subscription information of the IMPU changes or the UE state changes, the HSS needs to notify the pamm or PNM server, and the pamm or PNM server compares and determines whether to change the activation setting.

Step 1511, the HSS returns a response for setting the subscription identifier to the pancam/PNM server to identify whether the subscription is successful.

The steps 1510 and 1511 are only necessary steps for the first activation, and if the first activation is performed, the subscription operation is already performed, and the subscription does not need to be repeated in the subsequent activation.

Step 1512, the PANM server returns an activation response to the UE, indicating whether the activation operation is successful.

The activation process allows the partial services activated globally to be successfully activated, so if the activation is successful, the activation response message needs to carry the service code, IMPU, and PNE identifier that are successfully activated.

Step 1513, the UE forwards the activation response to the PNE, and when the activation is successful, the response needs to carry the successfully activated service code and the instance id of the PNE, and the activation process of the PNE is ended.

Example three:

in the third embodiment, the PNE is an ME with a wireless access capability. After the PANM server can identify the ME, namely after the ME joins the PAN, the PANM server configures the private network service access authority in the PAN of the ME. In this embodiment, a feature tag mechanism is employed to identify the PNE. Referring to fig. 16, fig. 16 is a schematic structural diagram of a service configuration module in the third embodiment of the present invention. The service configuration module comprises: the access authority information acquisition module and the routing prohibition module; wherein,

an access authority information acquisition module, configured to acquire access authority information of the PNE by adding the PNE to the PAN;

and the route forbidding module is used for indicating the S-CSCF to carry out route control by utilizing the identification information of the PNE according to the access authority information of the PNE after receiving the call initiated by the calling party, and forbidding the call to be connected to the PNE.

Referring to fig. 17, fig. 17 is a flowchart of identifying PNE in PAN in the third embodiment of the present invention. The process comprises the following steps:

the description of step 1701 may be similar to that of step 1201 described above.

The description of step 1702 may be similar to that of step 1202 described above.

The description of step 1703 may be similar to that of step 1203 above.

The description of step 1704 may be similar to that of step 1204, described above.

And step 1705, the UE and the ME interact with the PANM server through the Ut interface to complete the process of adding the PAN. The PANM server joins the PAN through the ME, acquires the identification information of the ME, wherein the identification information is the instance id of the ME. And the PANM server joins the PAN through the ME, and further acquires the access authority information of the ME, namely whether other terminals except the PAN are allowed to access the ME and the like.

Step 1706, the calling party initiates a call, the call signaling of which is sent to the S-CSCF.

In this step 1706, when a call needs to be connected to the terminal equipment of the called subscriber, the call is first sent to the S-CSCF. As shown in fig. 17, the call signaling initiated by the calling party may be an INVITE message of SIP.

Step 1707, the S-CSCF triggers the call signaling to the PANM server according to the iFC.

Step 1708, the PANM server decides the terminal device allowed to connect the call as UE according to the access right information of UE and ME, and ME is prohibited to connect the call. The pancm server may fill in the presence tag type parameter content of the Accept-Contact header field in the INVITE message as terminating identifier id of the UE, and fill in the Reject-Contact header field content as terminating identifier id of ME1 to indicate the caller preference, and return this INVITE message to the S-CSCF.

Step 1709, the S-CSCF receives the INVITE message, and locates registration connection of the terminating id of the UE, that is, the S-CSCF fills the Request-URI in the INVITE Request as the content of contact _1, and issues the INVITE message. And transmitting 403(Forbidden) message to the ME, so far, the process of configuring the private network service access authority of the ME in the PAN is ended.

The foregoing steps 1708 to 1709 are specific implementations in which the PANM server prohibits the PNE from continuing the call according to the access right of the PNE, instructs the S-CSCF to perform routing control by using the identifier information of the PNE, and prohibits the call from continuing to the PNE.

In the third embodiment, the PNE joins the PAN through the PAN server, so that the PAN server can identify the PNE in the PAN that belongs to the same user as the UE, and thus, the user can make full use of terminals or terminal peripherals with different capabilities to obtain better service experience.

In summary, in the foregoing technical solution provided in the embodiment of the present invention, the panc server obtains the identification information of the PNE in the PAN through the PNE in the process of joining the PAN, identifies the PNE in the PAN, which belongs to one user with other PNEs or UEs, by using the identification information of the PNE, and identifies the PNE based on the identification information of the PNE in the PAN, and performs service configuration on the PNE, such as activation configuration of redirection service of the PNE, issuing configuration of redirection service, private network service configuration, and the like.
