Description

A kind of method for network access, equipment and system

Technical field

The present invention relates to communication technical field, particularly relate to a kind of method for network access, equipment and system.

Background technology

Along with the development of wireless communication technology, frequency spectrum resource has become especially nervous.In order to obtain 3GPP (3rdGenerationPartnershipProject, 3G (Third Generation) Moblie standardization body) LTE (LongTermEvolution, Long Term Evolution) design object of high-speed radio broadband access formulated, according to existing spectrum allocation schemes, the large broader frequency spectrum being positioned at higher frequency band can be utilized to obtain relatively large network capacity.But the path loss due to this frequency range is relative with penetrating damage all comparatively large, is difficult to realize the good network coverage, making indoor and hot spot region covering will there is more blind spot, therefore, various little base station can be adopted to carry out benefit to above-mentioned zone blind.But, for some region, because its cable wiring manufacture is very difficult, thus make the cloth station cannot being carried out little base station by wired mode.

In order to solve the problem, 3GPPR10 introduces this new base station type of Relay (relaying) base station, and the mode by wireless backhaul sets up new site, thus can be community and bring larger coverage and power system capacity.Particularly, relaying technique refers to: at down direction, and the signal that UE (UserEquipment, user terminal) is issued in base station does not directly issue UE, but first issues a Relay base station, and then is transmitted to UE by Relay base station; At up direction, the upward signal of UE does not also directly issue base station, but first issues a Relay base station, and then is transmitted to base station by Relay base station.By Relay base station, and dead angle can be covered service signal is provided for the serious area of shadow fading in community, if Relay base station is placed in original cell coverage area simultaneously, as some hot zones and indoor, the effect improving power system capacity also can be played.

Particularly, on the basis of the LTE network framework (specifically can as shown in Figure 1) of 3GPPR8, the network architecture that R10 introduces behind Relay base station can be as shown in Figure 2.From Fig. 1 and Fig. 2, the network architecture introduced behind Relay base station can be as described below relative to the change of each network element in legacy network framework:

(1), Relay base station has been increased newly: described Relay base station, as special UE, can be common UE and sets up wireless backhaul passage between Relay base station to DeNB (donor base station); As particular base station, can be common UE and wireless access service is provided.

(2), DeNB has been transformed: improved DeNB can support SAE (SystemArchitectureEvolution, System Architecture Evolution) GW (Gateway, gateway) function; Can be the corresponding IP of Relay base station assigns (InternetProtocol, procotol) address; Further, can be common UE and the passage of the wireless backhaul between Relay base station to DeNB is provided;

(3) MME (MobilityManagementEntity, Mobility Management Entity), has been transformed: improved MME can carry out authentication to the access of Relay base station; Further, can be the session channel of Relay base station foundation to DeNB;

(4), HSS (HomeSubscriberServer has been transformed, home subscriber server): improved HSS can increase in the CAMEL-Subscription-Information for Relay base station that to be used to indicate described CAMEL-Subscription-Information be type and be the indication information of the CAMEL-Subscription-Information of Relay base station, as RelayNodeIndicator (via node indication information or relay base station indication information);

(5) BOSS (abbreviation of Business & OperationSupportSystem, i.e. business operation support system), has been transformed: improved BOSS can be new user type (i.e. Relay base station) and opens an account.

In addition, from Fig. 1 and Fig. 2, the network architecture introduced behind Relay base station can be as described below relative to the change of each interface in legacy network framework:

(1), Un interface has been increased newly: described Un interface is the wave point between Relay base station and DeNB;

(2), increased S11 interface newly: described S11 interface is the interface between the SAEGW logical ne in MME and DeNB, be responsible for the session management of Relay base station, function and flow process and existing network S1 interface completely the same;

(3), transformed S1 interface: DeNB opens the station stage, MME issues the base station tenability information (namely whether supporting Relay base station functions) of MME to DeNB by improved S1 interface; When Relay opens station in base station, DeNB by improved S1 interface to MME report of user type (whether being namely Relay base station) and SAEGW logical ne, as S-GW (ServingGateway, gateway) and the information such as address of P-GW (PacketDataNetworkGateway, packet data network gateway);

(4), transform S6a interface: issuing of Relay base station CAMEL-Subscription-Information can be realized by improved S6a interface, wherein can carry special user type instruction (as RelayNodeIndicator).

(5), Soap interface has been transformed: opening an account of new user type (as RelayNode) can be realized by improved Soap interface.

Correspondingly, after network element and interface variation, can there is following change in network insertion flow process:

(1), open an account in flow process user: Relay base station is as the special UE of a class, its USIM (UniversalSubscriberIdentityModule, Global Subscriber identification card) calorie requirement could use after opening an account, and needs the type (RelayNode) of designated user when opening an account;

(2), in the S1 interface Establishing process of DeNB: DeNB is as the eNodeB of enhancement mode, S1 interface establishment stage when electrifying startup and between MME, S1SETUPREQUEST (S1 interface sets up message) can be initiated to MME, and the S1SETUPRESPONSE (S1 interface sets up response message) supporting that the MME of Relay base station functions returns can be received, wherein, MMERelaySupportIndicator (for expressing support for the indication information of Relay base station functions) can be carried in described S1SETUPRESPONSE, when being convenient to the access of follow-up Relay base station, DeNB can choose the MME supporting Relay base station functions,

(3), in the attachment flow of Relay base station: the attachment of Relay base station is divided into two stages to carry out, wherein, the attachment in stage one is similar to common UE attachment flow, Relay base station is attached to P-GW, then base station configuration information is obtained by FTP (FileTransferProtocol, file transfer protocol (FTP)); During the attachment in stage two, DeNB selects the MME supporting Relay base station functions, and in S1 message " InitialUEMessage (initial UE message) ", carry the information such as address (i.e. DeNB address) and RelayNodeIndicator of SGW and PGW, afterwards, MME is according to SGW and the PGW address of carrying in " InitialUEMessage ", and set up session connection between corresponding DeNB, be Relay base station assigns IP by DeNB.And common UE is when adhering to from eNodeB, in S1 interface message, do not carry the address information of SGW and PGW, but to be inquired about by DNS (DomainNameSystem, domain name system) by MME and obtain;

(4) in the attachment flow of the common UE, under Relay base station range: the NAS (NonAccessStratum of UE, Non-Access Stratum) the user face passage of signaling by building up between Relay base station and DeNB, be separated via DeNB, mail to MME; And the user data of UE mails to S-GW via DeNB separation.

As shown in the above, in the prior art, in order to support the access of Relay base station, need to transform largely interfaces such as core network element and S1, S6a and Soap such as DeNB, MME, HSS and BOSS, thus cause network design speed comparatively slow and greatly can improve the lower deployment cost of network.
