Embodiment 4
The embodiment of the present invention provides a kind of method of mobile management, change that both can perception CS location information domain, again can compatible ISR mechanism, referring to Fig. 4, with UE from E-UTRAN network insertion GERAN/UTRAN network, the scene of returning to the E-UTRAN network from the GERAN/UTRAN network again is example, and the processing procedure of mobile management is described in detail in detail, comprising:
301:UE access E-UTRAN network, be accomplished to the registration of MME, and be established to the IP tunnel of VANC;
Wherein, UE, in the process to the MME registration, obtains the TAI list information that MME provides, and UE preserves this TAI list.Therefore, when UE moves in this TAI list scope, UE can not trigger the TAU flow process with MME.
Concrete, UE is established to the process process of setting up the PDN that VoLGA is relevant (Packet Data Network, Packet Data Network) connection that namely UE initiates of the IP tunnel of VANC.
302:UE is accomplished to the registration of VANC;
Wherein, to be accomplished to the registration of VANC be also that UE is in the VoLGA login state to UE.
Wherein, at UE, in the VANC registration process, VANC can distribute VANC TAI list and VoLGA LAI to UE.UE preserves this VANC TAI list, and when UE moves in this VANC TAI list scope, UE can not trigger the VoLGA register update flow process with VANC.
303:UE is accomplished to the registration of MSC by VANC;
Wherein, at UE, in the process of MSC registration, MSC to UE, is designated as E-UTRAN-LAI by the active position area information LAI information distribution of the UE of its record, and this E-UTRAN-LAI information is identical with the VoLGA LAI in step 302.
Further, after UE is accomplished to the registration of MSC by VANC, UE preserves above-mentioned LAI information.
304:UE is from the E-UTRAN Network Mobility to the GERAN/UTRAN network;
305:UE perception connecting system changes, and while moving to the area of coverage of GERAN/UTRAN network, to SGSN, sends position updating request (RAU Request) message;
Wherein, this location update request message can be RAU Request message or RA/LA associated update request message.
306: inconsistent if UE perceives the E-UTRAN-LAI of the LAI information of current access and preservation, UE also can be initiated to the independent position update flow of MSC;
Wherein, this LAI information is known from the broadcast message of access network elements.
Wherein, the more new technological process to MSC that UE initiates can be the LAU flow process.Complete that UE initiates after the more new technological process of MSC, MSC records the positional information of UE again, for with step 303 in E-UTRAN-LAI distinguish, the positional information of UE now is defined as to GERAN/UTRAN-LAI, and MSC covers this GERAN/UTRAN-LAI information or replaces the E-UTRAN-LAI information of preserving before it.Otherwise, if UE from GERAN/UTRAN network insertion E-UTRAN network and activate ISR, covers E-UTRAN-LAI information or replaces the GERAN/UTRAN-LAI information of preserving before MSC.
Further, because RA and LA have certain corresponding relation, therefore, can initiate respectively that RA upgrades as step 305, step 306, LA new technological process more, also can in a step, initiate RA/LA associated update flow process simultaneously.
In 307:SGSN and E-UTRAN network, the MME of service UE is mutual, obtains the ISR ability information of MME;
Wherein, the ISR ability information refers to whether MME supports ISR mechanism.
308:SGSN selects the state of activation of ISR according to the ISR ability information of the MME of service UE in self-ability and E-UTRAN network, and sends position renewal response message to UE;
Wherein, this position is upgraded response message and is comprised the RAI information that SGSN provides to UE, can also comprise ISR information.Wherein, ISR message is used to indicate ISR state of activation (ISR activation/ISR is inactive).When ISR activates, when UE moves between the TA of the RA of recorded GERAN/UTRAN network and E-UTRAN network, UE can not trigger the mobile management flow process in PS territory, as RAU flow process or TAU flow process.
Further, in step 304, UE after the GERAN/UTRAN network, also needs to make UE to keep the VoLGA login state from the E-UTRAN Network Mobility.It is a kind of according to the ISR state of activation in step 308 that the present embodiment provides, by setting, go registration timer to keep the method (referring to method one, two, three) of VoLGA login state, certainly, the present embodiment does not limit the concrete grammar that keeps the VoLGA login state.
When UE resides in the E-UTRAN network based on VoLGA, VANC distributes one to UE and removes registration timer, and this goes registration timer to initiate to go register flow path for triggering UE to VANC.For example, at UE, carry out in the register flow path or register update flow process of VANC, in the message that VANC sends to UE, carry registration timer " deregister on rove-out ".When UE operates under the VoLGA mode of operation, be that CS territory service Radio Resource entity is GA-CSR (Generic Access-Circuit Switched Resources, common access-circuit switched resource) (VoLGA A pattern) or GA-RRC (Generic Access-Radio Resource Control, common access-Radio Resource is controlled) when (VoLGA Iu pattern), UE does not need to start this timer.When the CS territory of UE service Radio Resource entity is transferred to GERAN RR (Radio Resource from GA-CSR or GA-RRC, Radio Resource) or UTRAN RRC (Radio Resource Control, Radio Resource is controlled) time, for example, UE in GA-RC REGISTERED state is from E-UTRAN network insertion GERAN/UTRAN network, connecting system changes, and UE starts this timer.When UE resides in the GERAN/UTRAN network, and described timer expiry (or claiming to overflow), UE initiates the register flow path that goes to VANC.
Remove registration timer by setting, keep the process of VoLGA login state, the present embodiment provides three kinds of concrete processing methods.
Method one, the trigger condition of going registration timer to start is that Access Network changes, and comprising:
UE is from EUTRAN access GERAN/UTRAN network, connecting system changes, UE transfers to GERAN RR or UTRAN RRC by CS territory service Radio Resource entity from GA-CSR or GA-RRC, and registration timer is removed in the UE startup, and network side arranges a maximum duration for this removes registration timer;
, before reaching maximum duration (while going registration timer not overflow), if, after UE receives the indication of network side activation ISR, stop this and remove registration timer, be also that UE continues to keep the VoLGA login state;
Before reaching maximum duration, if UE receives the indication of network inactive I SR, UE continues to maintain registration timer, is also that UE continues to keep the VoLGA login state; , if reach maximum duration (while going registration timer to overflow), UE carries out and removes register flow path.
Method two, the ISR state of activation that the trigger condition of going registration timer to start is perception after Access Network changes comprises:
UE is from EUTRAN access GERAN/UTRAN network, and connecting system changes, and UE transfers to GERAN RR or UTRAN RRC by CS territory service Radio Resource entity from GA-CSR or GA-RRC, and UE does not start this and removes registration timer;
If follow-up perception ISR activates, for example receive the indication ISR activation that SGSN sends, UE does not start this and removes registration timer;
For example, if follow-up perception ISR un-activation, receive the indication ISR un-activation that SGSN sends, UE starts this and removes registration timer.
Method three, according to the change of Access Network, go this registration timer stop and make zero, and comprising:
UE is from EUTRAN access GERAN/UTRAN network, start the duration sum of the timer that periodically updates the deexcitation ISR that timer duration (periodically update in the E-UTRAN network in timer duration or GERAN/UTRAN network and periodically update timer duration) and UE preserve go registration timer, network side to arrange that its maximum duration is longer than that UE preserves;
Go before registration timer do not overflow, when UE returns to the EUTRAN network from the GERAN/UTRAN network, will go registration timer to stop and make zero.
Comprehensive above-mentioned three kinds of methods, as the UE of GA-RC REGISTERED state, from E-UTRAN network insertion GERAN/UTRAN network, no matter whether ISR activates, and can continue to select to keep GA-RC REGISTERED state, does not need to carry out and remove register flow path to VANC.And, GA-CSR or GA-RRC, and GERAN RR or UTRAN RRC, can be simultaneously as the service Radio Resource entity of UE, in this case, UE both can process and VANC between mutual, can process again and the access network elements of GERAN/UTRAN network between mutual, for example with BSS (BaSe Station Subsystem, base station sub-system)/RNC (Radio Network Controller, radio network controller) between mutual.
309: change in the UE of VoLGA login state perception CS location information domain, send register update upstream message (the second register update flow process) to VANC;
The register update flow process that the present embodiment will be initiated at the GERAN/UTRAN network is called the second register update flow process.With the difference of the first register update flow process, be, what in the up registration update message in the second register update flow process, carry is the positional information of GERAN/UTRAN network, for example, and RAI or LAI information.
Wherein, the positional information of in this register update up (GA-RC REGISTER UPDATE UPL INK) message, carrying current GERAN/UTRAN network, for example, the information such as RAI, LAI, CI.
The positional information that 310:VANC provides according to UE, provide service if can continue as UE, and VANC replys register update downstream message (GA-RC REGISTER UPDATE DOWNLINK) to UE;
The positional information that 311:VANC provides according to UE, provide service if cannot continue as UE, and VANC replys the registration Transfer Message to UE;
