Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein.
Current network slices are generally managed directly by an operator, for example, a third party server informs the operator of member management requirements, and the operator performs corresponding operations on members of the network slice according to the member management requirements of the third party server. And the third party server cannot directly manage.
Based on the above, the embodiment of the invention provides a method and a system for opening member management capability of a network slice, which can realize member management of the third party platform open network slice by calling network control capability.
In particular, embodiments of the present invention are further described below with reference to the accompanying drawings.
It should be understood, however, that the following examples provided herein may be combined with one another to form new embodiments, so long as they do not conflict.
Fig. 1 is a schematic structural diagram of a member management capability open system of a network slice according to an embodiment of the present invention. As shown in fig. 1, the capability opening system 100 includes: a capability open platform (Common API Framework, casf) 101, a communication services management platform (Communication Service Management Function, CSMF) 102, and a unified data management module (Unified Data Management, UDM) 103. The third party server 200 may communicate with the CSMF102 and UDM103 via the casf 101 to enable member management of the network slice.
The third party server 200 may be an application server of a third party developer or other partner, government enterprise, or individual user. For example, the third party server 200 is a server of a game, or the like. The third party server 200 implements management of game members through the capability opening system 100.
Wherein the casf 101 may set an application program interface (Representational State Transfer Application Programming Interface, rest API) representing the status transfer, thereby providing the Rest API for the third party server 200, thereby enabling communication between the casf 101 and the third party server 200. In the above manner, the network capability of the operator is opened to the third party server 200 call through the standard Rest API, so that the third party server 200 uses the Rest API and the software development kit to develop the network capability of the operator.
The CSMF102 is used to implement management of network slices, such as ordering slices, changing slices, releasing slices, slice status monitoring, and the like. The casf 101 may also set a Rest API to provide a Rest API for CSMF102 to enable communication between the casf 101 and CSMF102 to enable the casf 101 to call the Rest API of CSMF 102.
Optionally, the CSMF102 may also communicate with a slice management platform (Network Slice Management Function, NSMF), the CSMF102 enabling management of slices according to slice management requirements by sending slice management requirements to the NSMF.
The UDM103 is a user data management network element of the 5G unified data management module, and is configured to be responsible for unified management of 5G user data, for example, management of various user subscription data, management of user authentication data, management of user identification, user identification processing, hiding of a privacy-protected user identifier, access authorization based on user data, service registration management of user equipment, user lawful interception, and the like. The UDM103 may be located in the core network. CSMF102 communicates with UDM103 via a SOAP interface to enable third party server 200 to communicate with UDM103 via casf 101 and CSMF102 to enable member management of the third party user's open network slice.
Alternatively, the number of UDMs 103 may be plural, and the plurality of UDMs 103 are respectively in communication with the CSMF 102. Wherein, each UDM103 may be used to implement different user management functions, and then, according to different requests of the third party server 100, a request is initiated to the corresponding UDM 103. Of course, in some other embodiments, one third party server 200 may correspond to one or more UDMs 103, and then initiate a request to the UDM103 to which the third party server 200 corresponds.
Optionally, the member management system 100 may further include: billing center 104. The billing center 104 communicates with the CAPIF 101 and performs information synchronization with the CAPIF 101, so that the billing center 104 can calculate the fee for member management based on the synchronized information and can charge the third party server 200.
Fig. 2 is a flow chart illustrating a method for opening member management capability of a network slice according to an embodiment of the present invention. The method may be applied to the member management capability opening system 100 of the network slice in fig. 1. As shown in fig. 2, the method includes:
step 310, the capf receives a terminal-based slice member subscription request sent by the third party server.
The terminal may be a User Equipment (UE), and the UE may include a smart phone, a personal computer (Personal Computer, PC), a Personal Digital Assistant (PDA), a tablet computer, a notebook computer, a car-mounted computer (carpenter), a palm game machine, smart glasses, a smart watch, an unmanned plane, a wearable device, a virtual display device, a display enhancement device (e.g., google Glass, gear VR), and the like.
Prior to step 310, the method may further comprise:
step 301, the third party server sends a terminal-based slice member subscription request to the casf.
The slice member signing request refers to a request for triggering the subscription of the terminal and the network slice. When a terminal needs to access a certain network slice, the terminal can access the network slice after signing up with the network slice. In this embodiment, the third server generates a subscription request of the slice member according to the information of the terminal, and then sends the subscription request of the slice member to the casf.
Step 310 may specifically be: and the CAPPIF receives a slice member subscription request sent by the third party server through a Rest API of the CAPPIF.
Step 320, the caspi sends a slice member subscription request to the UDM by calling the Rest API of the CMSF.
The subscription request of the slice member carries subscription identification information. The subscription identification information refers to information indicating a terminal and a network slice for which subscription is required.
Specifically, step 320 may include: the CAPPI sends a slice member subscription request to a Rest API of the CMSF; the CMSF converts the subscription identification information carried by the slice member subscription request into the subscription identification information in the SOAP format, and sends the subscription identification information in the SOAP format to the UDM.
Step 330, the UDM receives a terminal-based slice member subscription request sent by the caspi through the Rest API calling the CMSF.
Specifically, step 330 may include: the UDM receives the signature information in SOAP format sent by the CMSF.
And 340, adding the terminal into a network slice corresponding to the terminal according to the subscription identification information by the UDM to complete the subscription of the terminal.
Specifically, step 340 may include: and adding the terminal into a network slice corresponding to the terminal by the UDM according to the subscription identification information in the SOAP format so as to complete the subscription of the terminal.
The subscription identification information may include terminal identification information and slice identification information. The terminal identification information may include: international mobile subscriber identity (International Mobile Subscriber Identity, IMSI), mobile station identification number (MobileSubscriberInternationalISDNNumber, MSISDN), HLR serial number. The IMSI is an identification number which is used for distinguishing different users in the cellular network and is not repeated in all the cellular networks, namely an identification number of a commonly-called SIM card; the MSISDN is the user number given to the SIM card, namely the commonly-called mobile phone number; the HLR sequence number refers to the sequence number attributed to the location register. The slice identification information may include single network slice selection assistance information (Single Network Slice Selection Assistance Information, S-NSSAI). The S-NSSAI may include a slice traffic type indicating traffic characteristics and traffic behavior of the desired slice. Optionally, in some other embodiments, the slice member subscription information may further include slice attribute information, where the slice attribute information is used to represent an attribute of the slice.
Step 340 may specifically include:
step 341, determining a network slice corresponding to the terminal by the UDM according to the slice identification information;
and 342, generating subscription data of the terminal by the UDM according to the terminal identification information and the determined network slice so as to complete subscription of the terminal.
Wherein, there are several different network slices in the network, and these network slices are suitable for users with different demands respectively. Therefore, when a subscription request of a slice member is initiated, slice identification information corresponding to the terminal can be generated according to the requirement of the terminal and the existing network slice, so that the UDM can determine the network slice corresponding to the slice identification information of the terminal according to the slice identification information of the terminal and the corresponding relation between the preset slice identification information and the network slice, and further determine the network slice corresponding to the terminal.
After determining the network slice corresponding to the terminal, the UDM generates subscription data of the terminal according to the terminal identification information and the determined network slice, so as to add the terminal to the determined network slice, thereby completing subscription of the terminal and the determined network slice.
In some embodiments, the method further comprises: step 350, the UDM returns the signing result.
After the UDM completes signing of the terminal, the UDM returns a signing result to the CSMF, after the CSMF receives the signing result, the CSMF returns the signing result to the CAPFA, and the CAPFA returns the signing result to the third party server.
According to the embodiment of the invention, the CAPIF receives the subscription request of the slice member sent by the third-party server based on the terminal, and initiates the subscription request of the slice member to the UDM through the Rest API of the CSMF, so that the UDM adds the terminal into the network slice corresponding to the terminal according to the subscription identification information carried by the subscription request of the slice member, so that the subscription of the terminal is completed, thereby member management in the network slice is provided for the third-party server to use, member management of the third-party server for opening the network slice is realized, the third-party server can be helped to realize more convenient management of the slice user, communication perception of the user when the user uses the service is improved, and cost of managing the slice user is effectively reduced.
In some embodiments, prior to step 301, the method further comprises:
step 361, the third party server sends authentication information to the CAPPIF;
step 362, the CAPIF authenticates the third party server according to the authentication information;
step 363, if the CAPIF determines that the authentication of the third party server is passed, the CAPIF allows the third party server to access;
step 364, if the CAPIF determines that the authentication of the third party server is not passed, the CAPIF does not allow the third party server to access.
The authentication information may include an account number, a password, and the like, and the third party server may pre-store the account number and the password in the caif to register, and the caif may authenticate the third party server by comparing the pre-stored account number password with the account number password sent by the third party server. When the CAPPIF determines that the authentication of the third party server is passed, the CAPPIF allows the third party server to access, thereby enabling the third party server to access the Rest API of the CAPPIF.
When the CAPPIF determines that the authentication of the third party server is passed, the CAPPIF can return an authentication token to the third party server so as to inform the third party server that the authentication is passed.
In some embodiments, before the CSMF sends the subscription identification information in SOAP format to the UDM, the method further comprises:
step 371, CSMF judges whether the terminal has signed up according to signing identification information;
step 372, if it is determined that the terminal has subscribed, a subscribed notification is returned to the caspi;
if it is determined that the terminal does not sign a contract, step 373 is executed to send the sign information in SOAP format to the UDM.
The step 371 may specifically be: the CSMF can query the pre-stored subscription data, and judge whether the IMSI, MSISDN and S-NSSAI of the terminal exist in the pre-stored subscription data so as to judge whether the terminal is subscribed, if so, the terminal is determined to be subscribed, and if not, the terminal is determined to be not subscribed.
When it is determined that the terminal is subscribed, the CSMF returns a subscribed notification to the casf in step 372, so that the casf returns a subscribed notification to the third party server to inform the third party server that the terminal is subscribed.
In some embodiments, the method further comprises:
step 381, the CAPPIF synchronizes the charging information of the third party server to the charging center;
step 382, the billing center generates settlement information of the third party server according to the billing information.
Wherein, as shown in fig. 3, the operator may pre-plan the charging policy of member management of the 5G network slice, and configure the charging package of member management of the 5G network slice in a charging center (ESOP) by an administrator, thereby configuring the member management charging policy of the 5G network slice to the caspi. When the third party server carries out the registration application capability open account, the CAPIF synchronizes the registration information of the third party server to the charging center, and when the third party server calls the Rest API of the CAPIF, the CAPIF synchronizes the charging information of the third party server to the charging center, so that the charging center can generate the settlement information of the third party server according to the charging information and send the settlement information to the third party server so as to enable the third party server to carry out settlement.
Fig. 4 is a flow chart illustrating a method for opening member management capability of a network slice according to another embodiment of the present invention. The method may be applied to the member management capability opening system 100 of the network slice in fig. 1. As shown in fig. 4, the method includes:
step 401, a third party server sends authentication information to CAPIF;
step 402, the CAPPIF authenticates the third party server according to the authentication information;
step 403, if the CAPIF determines that the authentication of the third party server is passed, the CAPIF allows the third party server to access;
the steps 401 to 403 are the same as the steps 361 to 363 in the above embodiment, and are not repeated here.
Step 404, the third party server sends a terminal-based slice member modification request to the casf.
Wherein the slice member modification request refers to a request for triggering modification of subscription data between the terminal and the network slice. In this embodiment, the third server generates a slice member modification request according to the information of the terminal, and then sends the slice member modification request to the casf.
Step 405, the capf receives a terminal-based slice member modification request sent by the third party server, and sends a slice member subscription request to the CMSF.
The CAPIF receives a slice member modification request sent by the third party server through a Rest API of the CAPIF, and sends a slice member subscription request to the Rest API of the CMSF.
Step 406, the CSMF judges whether the terminal has signed up according to the modification identification information carried by the slice member modification request.
Wherein, the modification identification information may include terminal identification information and slice identification information, and the CSMF may determine whether the terminal has subscribed according to the terminal identification information and the slice identification information.
Step 407, if it is determined that the terminal has signed up, the CSMF converts the modification identification information into modification identification information in SOAP format, and sends the modification identification information to the UDM.
If the CSMF determines that the terminal has subscribed, that is, indicates that the terminal is a network slice for which subscription has been applied, a SOAP message is generated according to the terminal identification information and the slice identification information, and the SOAP message is sent to the UDM.
Step 408, the UDM modifies the subscription data of the terminal according to the modification identification information.
When the UDM receives the terminal identification information and the slice identification information, the UDM searches the current subscription data of the terminal according to the terminal identification information, so that a network slice currently subscribed by the terminal is determined, and a modified network slice is determined according to the slice identification information, so that the network slice currently subscribed by the terminal is replaced by the modified network slice, and the subscription data of the terminal is modified.
Step 409, UDM returns the subscription modification result.
After the UDM finishes the modification of the subscription data of the terminal, the UDM returns a subscription modification result to the CSMF, and after the CSMF receives the subscription modification result, the CSMF returns the subscription modification result to the casf, and the casf returns the subscription modification result to the third party server.
According to the embodiment of the invention, the CAPIF receives the slice member modification request based on the terminal sent by the third-party server, and initiates the slice member modification request to the UDM through the Rest API of the CSMF, so that the UDM modifies the subscription data of the terminal according to the modification identification information carried by the slice member modification request, thereby completing the member modification of the network slice, being capable of providing member management in the network slice for the third-party partner to use, realizing member management of the third-party server for opening the network slice, being capable of helping the third-party partner to more conveniently realize the management of the slice user, improving the communication perception when the user uses the service, and effectively reducing the cost of the slice user management.

the steps 501 to 503 are the same as the steps 361 to 363 in the above embodiment, and are not repeated here.
Step 504, the third party server sends a terminal-based slice member deletion request to the casf.
The slice member deletion request refers to a request for triggering deletion of subscription data between the terminal and the network slice. In this embodiment, the third server generates a slice member deletion request according to the information of the terminal, and then sends the slice member deletion request to the casf.
Step 505, the capf receives a terminal-based slice member deletion request sent by the third party server, and sends the slice member deletion request to the CSMF.
The CAPIF receives a slice member deletion request sent by the third-party server through a Rest API of the CAPIF, and sends the slice member deletion request to the Rest API of the CSMF.
Step 506, the CSMF judges whether the terminal has signed up or not according to the deletion identification information carried by the slice member deletion request.
The deletion identification information may include terminal identification information and slice identification information, and then the CSMF may determine whether the terminal has subscribed according to the terminal identification information and the slice identification information.
Step 507, if it is determined that the terminal has signed up, the CSMF converts the deletion identification information into deletion identification information in SOAP format, and sends the deletion identification information to the UDM.
