Step 101 ', when the transfer of data of GSM adopts GPRS, MM preserves the parameter that the last success is registered after receiving the message that the last success that LLC sends registers;
When the transfer of data of GSM adopts GPRS, send the ATTACH ACEEPT message that has the registering result parameter to MM by LLC, after M M receives LLGMM_UNITDATA_IND message, equally the undated parameter updStatus according to MM preserves the last parameter that succeeds in registration, and detailed process is as described in the step 101.
In this step, the message of receiving except the main body that sends message and MM is with step 101 is different, and other are identical, so do not elaborate at this.
In addition, after successfully registering for the last time, before the generation card was invalid, UE may also attempt registering with other PLMN, attempted each time after the registration, PLMN and the parameter relevant with registration change and all need be sent the lower floor of RR_UPDATE_PLMN_REQ message informing MM by MM, promptly notify the RR layer to upgrade and register relevant parameter, be i.e. update mode updStatus, the PLMN that forbids, lane place array lai_list, related service service and access technology AcT.
Step 102, when the transfer of data of GSM adopts non-GPRS, RR sends the invalid message of card to MM, execution in step 103 then;
MM receives AUTHENTICATION REJECT message, or the refuse information LOCATIONUPDATING REJECTED that receives, ATTACH REJECT, the Reason For Denial value of ROUTING AREA UPDATE REJECT etc. is #2, #3, #6, during #8, be that the update mode updStatus that UE is provided with non-GPRS respectively under the situation of MM circuit switching (CS) and MM packet switching (PS) is U3/GU3 at MM, and delete Temporary Mobile Subscriber Identity TMSI (Temporary Mobile Subscriber Identity)/Packet-TMSI (P-TMSI respectively, Packet TMSI), Location Area Identification LAI (Location Area Identity)/Routing Area Identifier RAI (Routing Area Identity), Ciphering Key Sequence Number CKSN (Ciphering KeySequence Number)/parameters such as GPRS CKSN, at this moment, the MM state is MM IDLE.NO-IMSI/GMM-DEREGISTERED.NO-IMSI.Wherein, NO-IMSI represents the sub-state of MM at idle (IDLE) state, and this state is applicable to the situation of MM CS, and NO-IMSI represents the sub-state of GMM in exit state (IMSI), and this state is applicable to the situation of MM PS.In the standard agreement, the MM layer comprises CSMM part and PS MM part, and therefore, here, the part of all "/" number fronts is represented the situation of CS, and the part of all "/" number back is represented the situation of PS, and it also is like this such situation occurring in the content of back.
Step 102 ', when the transfer of data of GSM adopts GPRS, MM receives the message that makes card invalid, execution in step 103 then;
When the transfer of data of GSM adopts GPRS, send AUTHENTICATIONAND CIPHERING REJECT message by LLC to MM, this message is represented authentication and encryption state refusal, this step is compared with step 102, the main body that just sends message is different with the message that MM receives, other guide and step 102 are identical, do not elaborate at this.
Step 103, RR send the message of sub-district gravity treatment to MM;
If RR has reselected the sub-district, RR reports the information of reselecting the sub-district by RR_ACT_IND, comprises neighbor cell nCi_list, the professional ability service of cell ID ci, the ci of lane place array lai_list, current selection along with the parameter that reports.Wherein, ci is used for the upper strata and judges whether the sub-district changes, and nCi_list represents the neighbor cell of available current area, in addition, represents the number of maximum cell ID ci that the nCi_list array can be preserved with MAX_LENTH_CI.
Step 104, MM send information updating RR layer to RR after judging cell change according to the gravity treatment message of receiving, make PLMN that last success registers and the parameter relevant with registration thereof available at the RR layer;
After MM judges cell change according to the gravity treatment message received, send RR_UPDATE_PLMN_REQ information updating RR layer, make PLMN that last success registers and the parameter relevant thereof available at the RR layer with registration to RR.
The parameter that step 105, MM notice RR use last success to register is initiated cell selecting and register flow path.
After MM sends the registration parameter of RR_UPDATE_PLMN_REQ information updating RR, send RR_ACT_REQ message, the parameter of using last success to register then enters normal register flow path, the MM state is updated to LOCATION UPDATING INITIATED/GMM-DEREGISTERED.ATTACH-NEEDED, this two states represents that all register flow path begins, after MM course RR had sent RR_ACT_REQ message, the MM of CS and the MM of PS were in this two states respectively.
RAT is the situation of UMTS, with RAT is that the situation of GSM is compared, except the main body of carrying out interacting message becomes MM and RRC by MM and RR, and between the two outside institute's interactive messages difference, other process step is all identical, so part identical with first embodiment in the second embodiment of the present invention is no longer elaborated, and the method flow of second embodiment of the invention may further comprise the steps as shown in Figure 2:
After step 201, RRC sent the message of last success registration to MM, MM preserved the parameter that last success is registered;
MM receives that the message that RRC sends is GMMAS_DATA_IND, and after MM received message, the undated parameter updStatus according to MM preserved the last parameter that succeeds in registration equally, and the detailed process and first embodiment are identical.
Equally, after successfully registering for the last time, before the generation card was invalid, UE may also attempt registering with other PLMN, attempted each time after the registration, PLMN and the parameter relevant with registration change and all need be sent the lower floor of RR_UPDATE_PLMN_REQ message informing MM by MM, promptly notify the RR layer to upgrade and register relevant parameter, be i.e. update mode updStatus, the PLMN that forbids, lane place array lai_list, related service service and access technology AcT.
Step 202, RRC send the invalid message of card to MM;
MM receives that the message that RRC sends is AUTHENTICATION AND CIPHERINGREJECT, can certainly be other message, and other the message content and first embodiment are identical.
Step 203, RRC send the message of sub-district gravity treatment to MM;
If RRC has reselected the sub-district, RRC reports the information of reselecting the sub-district by URRC_ACT_IND, along with the parameter that reports comprises lane place array lai_list equally, and the cell ID ci of current selection, the neighbor cell nCi_list of ci, professional ability service.
Step 204, MM send the information updating rrc layer to RRC, and the PLMN of last success registration and the parameter relevant with registration thereof can be used at rrc layer;
After judging that the sub-district changes, according to update mode updStatus, send parameters such as the lane place of the PLMN that last success registers and registration business by URRC_UPDATE_PLMN_REQ message, make the parameter of the PLMN that last success registers available again in the registration of back.
Step 205, MM send message to RRC, and the PLMN that uses last success to register then enters normal register flow path.
After MM sends the registration parameter of URRC_UPDATE_PLMN_REQ information updating RRC, send URRC_ACT_REQ message, the PLMN that uses last success to register then enters normal register flow path.The MM state is updated to LOCATION UPDATING INITIATED/GMM-DEREGISTER-ED.ATTACH-NEEDED.
From two top embodiment as seen, preserve the parameter that success is each time registered, after card lost efficacy, pick up the message of sub-district if receive the RR/RRC of lower floor report, MM upgrades the parameter of RR/RRC about registration, and the parameter of the last success registration of being preserved can be used, the parameter renegotiation that the last success of notifying the RR/RRC use to be preserved is then registered is newly initiated cell selecting, enter normal register flow path, UE is served normally, thereby guarantee the work quality of UE.Under the situation of the invalid generation of card, the service that obtains automatically again has promotional value to present travelling carriage.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
