Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of sending method and equipment of user terminal identification information.
Background technology
In the existing 2G/3G network; Through MCC (Mobile Country Code, mobile subscriber's country code)+MNC (Mobile Network Code, mobile subscriber's affiliated PLMN net code)+LAC (Location Area Code; Location Area Code)+RAC (Routing Area Code; The route area code)+the unique UE of sign (User Equipment, user terminal) of P-TMSI (Packet Temporary Mobile Subscriber Identity, Packet Temporary Mobile Subscriber Identity).Wherein MCC+MNC is the sign of PLMN (Pulic Land Mobile Network, PLMN); LAC+RAC can confirm the POOL (resource pool) in the PLMN; P-TMSI can confirm unique core network entity and the UE in the POOL.During the UE access network first time; SGSN (Serving GPRS Supporting Node; Serving GPRS Support Node) distributes a packet TMSI (P-TMSI) to be used for temporary mark to UE and be registered in this regional UE; Wherein comprise the SGSN in POOL of NRI (Network Resource Indication, network resource identifier) message identification.UE next time is notified P-TMSI and RAI (MCC+MNC+LAC+RAI) information that old SGSN distributes to new SGSN during re-accessing network, is used for the context that correspondence is asked in address that new SGSN parses correct old SGSN.At LTE (Long Term Evolution; Long Term Evolution) in the network; Same this problem that exists; Can pass through GUTI (Globally Unique Temporary Indication, global unique temporary identity)=unique UE of sign of MCC+MNC+MME (Mobile Management Entity, mobile management entity) Group ID+MME code+M-TMSI.Wherein M-TMSI is distributed by MME, and is unique in MME.MME Group ID+MME code forms the MME in the unique definite PLMN of MME identifier (MMEI).MCC+MNC+MMEI forms GUMMEI (Globally Unique MME Identifier, globally unique MMEID, the i.e. sign of core net node MME) and comes unique MME that confirms.During the UE access network, need the MCC+MNC+MME Group ID+MME code+M-TMSI that old MME distributes is notified to new MME, be used for new MME and parse the context that correspondence is asked in correct old MME address.
Simultaneously; UE also need select the information of core net node (selection of NAS (Non Access Stratum, Non-Access Stratum) node) to send to access network node in POOL access network node, is used for access network node unique CN (Core Network of selection in POOL; Core network) node; In UMTS (Universal Mobile Telecommunication System, conventional wireless communication systems), this information of selecting core net be NRI its be the part of P-TMSI.And in LTE, this selection information can be MME code, is used for eNodeB (evolved NodeB, evolution base station) and selects MME.
In 2G/3G, (UE sends to RAN (Radio Access Network to UE in RRC (Radio Resource Control, Radio Resource control) initial direct-sending message; Wireless access network) node) carries P-TMSI information and be used for the selection of CN node; And (UE sends to the CN node) carried P-TMSI and RAI is used for CN node identification UE in NAS message, and wherein, NAS message is transparent to the RAN node; The RAN node is not resolved NAS message, only carries out transparent transmission.
In the prior art, when UE inserted the 2G/3G network, if distributed P-TMSI to UE before the network, UE sent to the RAN node with this P-TMSI information so, and the RAN node is linked into correct CN node according to P-TMSI.If there is not the information of P-TMSI among the UE, UE will provide IMSI to insert, and this moment, access network node was selected appropriate C N node according to principles such as load balancing.
During the UE access network, no matter be to be used for the information that the CN node is selected to what the RAN node sent, still giving the information that is used to identify UE of CN node transmission all is fixed mode.In 2G/3G, UE carries P-TMSI and RAI information in NAS message, in the RRC initial direct-sending message, carries P-TMSI information and is used for the selection of CN node.
RAU of the prior art (Routing Area Update, Routing Area Update) flow process is as shown in Figure 1, and concrete steps are following:
Do not connect if set up RRC between step s101 UE and the RNC, set up RRC so and connect.
Step s102, set up RRC and connect after, UE sends initial direct-sending message to RNC, in this message, comprises RAU Request information and P-TMSI, RNC does not resolve RAU Request part and is transparent to SGSN.RNC will if RNC does not dispose this NRI information, will select a new SGSN according to principles such as load balancing according to the SGSN (if RNC can also be linked into former SGSN) before the NRI Information Selection among the P-TMSI.
Step s103, RNC send to the SGSN of selection with RAU Request information, comprise P-TMSI and RAI information among the RAU Request and are used for sign oneself.
If step s104 UE inserts new SGSN, new SGSN will be to old request contexts, and judges whether carry out safety function according to the information of response.
Step s105, SGSN judge whether carry out safety function, then carry out if desired.
If step s106 SGSN changes, the PDP Context that new SGSN is initiated to GGSN upgrades.
If step s107 SGSN changes, new SGSN is initiated to the position of HSS and upgrades, and HSS carries out the position deletion of SGSN until old.
Step s108, SGSN judge the RAU Request that can accept UE, will send RAUaccept message to UE.
Step s109, UE return RAU Complete message to SGSN and accomplish to confirm RAU.
The inventor finds that there is following shortcoming at least in prior art in realizing process of the present invention:
In the prior art; UE is NRI to the information that is used for the core net node selection that access network node provides, and changed pool if say UE, and new pool also has the NRI of identical configuration; This RAN node is the SGSN of this identical NRI of selection of mistake so, thereby can not reach the purpose of load balancing.In addition, information that is used for the selection of CN node that UE provides at present and the information of sign UE all are to carry according to fixing pattern, and in the RRC initial direct-sending message, carry P-TMSI information, and in NAS message, also carries P-TMSI information.In some cases, these information of carrying are redundant, cause the waste of resource.In addition in evolvement network; Two entity unifications of possible SGSN and MME; With regard to after need guaranteeing that UE passes through MME of EUTRAN (Enhanced Universal Terrestrial Radio Access Network strengthens universal land radio access web) access selection in a pool, insert like this if still pass through the 2G/3G of this pool; Then must choose the SGSN and the MME of this unification, and prior art can't realize this point.
