Abstract
The present invention relates to a method for selecting core network carriers, which has a core that when network adhesion or position registration is carried out in a shared network by UE which does not support network share, a user's IMSI is obtained by an RNC; then, the obtained user's IMSI is matched with an IMSI number segment in the RNC by the RNC, and the core network carrier takes the priority of being selected in core network carriers corresponding to the matched IMSI number segment when the user's IMSI is confirmed to be capable of matching with the core network carrier corresponding to the IMSI number segment. Thus, the probability of successful selection of the core network carrier can be increased by the present invention so that the core network which selects the core network carrier is more accurate. Thus, the success rate of the network adhesion or the position registration is increased.
Description
Technical field
The present invention relates to the communications field, relate in particular to the selection of core network operators.
Background technology
Agreement 3GPP TS 23.236 and the 3GPP TS 25.331 of 3GPP Release5 have introduced the IUFLEX characteristic; The agreement 3GPP TS 23.251 of 3GPP Release6 has introduced the MOCN networking, and the UE (seeing 3GPP Release 6 TS23.251) that shares of the UE that shares of UE network enabled under MOCN networking situation and non-network enabled is in position register request or adhere to the selection scheme of asking to carry out core network operators.
As shown in Figure 1, typical MOCN (Multi-Operator Core Network, MOCN) and networking structure have been provided based on the IU FLEX of the IU FLEX technology among the 3GPP TS 23.251 net.Wherein, Operation CN-A1, Operation CN-A2, Operation CN-A3 and RAN-1, RNC-2 form IU FLEX networking; Operation CN-B1, Operation CN-B2 and RAN-1, RNC-2 form IU FLEX networking; The CN of the CN of Operation-A, the CN of Operation-B, Operation-C and RAN-1, RNC-2 form the MOCN networking.
Prior art related to the present invention is the location registers of the UE (seeing 3GPP Release 6 TS23.251) that shares for network enabled not in the MOCN networking of describing in 3GPP TS 23.251 or the flow process of network attachment, and it is as follows as shown in Figure 2:
RNC selects the foundation of core net to be: according to NRI among the IDNNS or picked at random (Selection of CN node is based on NRI (Valid or inValid) if present inIDNNS or by random selection.), see 3GPP TS 23.251
After step 4, core net are received Initial UE message, will respond Reroute Command (route reselection) or Reroute Complete (route is finished) message.
After core net is adhered to the preceding core net of success or is directly obtained user's IMSI there from UE from Initial UE message or from UE, core net is according to IMSI (International MobileSubscriber Identity, international mobile subscriber identity) determine the user in this operator, whether allow the roaming, if this core network operators does not allow this user's roaming, then user network adheres to and can fail.
Step 6 when RNC receives Reroute Command message, is selected next core network operators, and RNC sends the core net B of a new message to other selection then, and affix user's IMSI.
When RNC receives Reroute Command message, select the algorithm of next core network operators to be: in the core network operators of also not selecting, to select at random.
If core net B allows the PLMN roaming of user IMSI correspondence, then execution in step 7, and core net B is according to carrying out flow processs such as authentication, encryption between attachment flow and the UE.
After authentication is passed through, execution in step 8, core net and HLR (Home Location Register, attaching position register) carry out interacting message, obtain user data.
If the user data roaming forbids that then execution in step 9, core net B sends RerouteCommand (route reselection) message and gives RNC, comprising Reason For Denial value and IMSI.
Step 11, if core net C allows PLMN (Public Land MobileNetwork, the Public Land Mobile Network) roaming of user IMSI correspondence, core net C carries out flow processs such as authentication, encryption according to attachment flow.
Execution in step 13 afterwards, and core net C sends Reroute Complete (route is finished) message and wherein comprises Attach accept to RNC.RNC sends to the user and adheres to success message to UE.
Execution in step 15 afterwards, and UE makes response, send Attach Complete message to core net C.
By the technical scheme of prior art as can be seen, the UE that shares for network enabled not, RNC receives the Initial Direct Transfer message that this UE sends, and selects the algorithm of core net to be: according to NRI among the IDNNS or picked at random (Selection of CN node is based on N RI (Valid orinvalid) if present in IDNNS or by random selection.); When RNC receives RerouteCommand message, select the algorithm of next core network operators to be: in the core network operators of also not selecting, to select at random.Prior art can cause following defective to occur based on the system of selection of this blindness:
If it is a plurality of that the operator of 1 core net has, one time the user adheres to or location registers, may cause RNC to reselect core net many times, and is consuming time oversize, may cause the user to adhere to or the location registers failure.And,
2, select this processing mode of core network operators may cause the load of RNC to raise at random, very big to the performance impact of RNC.
