It is standby.
Background technique
CSFB (Circuit Switched Fallback, circuit domain dropping) be LTE (Long Term Evolution,
Long term evolution) mode that voice communication is realized in system, carried out under LTE network by LTE terminal TA (Tracking Area,
Tracking area) realization of/LA (Location Area, position area) associated update, in MME (the Mobile Managenment of LTE
Entity, mobility management entity) (Global System for Mobile Communication, the whole world are mobile logical with GSM
Letter system) MSC (Mobile Switching Center, mobile switching centre) be completed at the same time registration, when terminal is in LTE net
When initiating audio call in network or receiving voice page message, carried out using the GSM frequency point specified in LTE downlink redirecting signaling
It falls after rise, then initiates the process of audio call or response paging at GSM.
Co-location renewal process, which includes MME, to be initiated co-location to MSC and updates request, MSC to HSS (Home
Subscriber Serve, home subscriber server) initiate CS (Circuit Switched, circuit switching) domain location updating mistake
Journey.After the completion of co-location updates, MME records UE (User Equipment, user equipment) corresponding MSC, and MSC records UE pairs
The MME answered, HSS record the MSC where user.As the CSFB that UE is initiated as caller (MO, MO Mobile Originated)
Calling or SMS, MME need to find MSC according to record；User receives CSFB calling or SMS (the Short Message of MT
Service, short message), HSS can find the corresponding MSC of the UE according to record, and it is corresponding that MSC according to record finds the UE
MME。
Existing CSFB co-location renewal process is unidirectional update, i.e., can only initiate co-location from the side MME to the side MSC
Update request, MSC can not active initiation co-location update.Once UE causes in practical place MSC and HSS because of certain reason
The MSC of record is not consistent, then must trigger UE by MME and re-start co-location renewal process, and MSC is also required to really
It protects and goes to update the MSC ID recorded in HSS.If the MSC recorded in HSS is not consistent with actual MSC, UE conduct will result directly in
CSFB audio call and SMS failure when called (MT, Mobile Terminated).
Since CSFB is mainly to pass through the technical solution that MSC is user's realization audio call, the side MSC can be sent out in time
Existing UE's uses exception.Once UE is not inconsistent the feelings for called failure occur because of the MSC where the MSC recorded in HSS the and UE is practical
Condition, the side MSC can quickly find reason by modes such as tracking signalings, but according to current co-location more new technological process MSC
Can not initiate co-location renewal process, can only remove first the corresponding VLR of the UE (Visitor Location Register,
VLR Visitor Location Register) register information, MME where UE is then found, then contact the side MME and user is forced to be registered again to solve this
Problem.It can be seen that noting abnormalities from MSC up to again notice MME forces user to register to guarantee the intermediate ring passed through in HSS
Save it is more, increase co-location update time delay.

Below in conjunction with Figure of description, preferred embodiment of the present invention will be described, it should be understood that described herein
Preferred embodiment only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention, and in the absence of conflict, this hair
The feature in embodiment and embodiment in bright can be combined with each other.
Inventors have found that the existing co-location renewal process for the UE for supporting CSFB is one unidirectional updated
Journey, i.e., can only from the side MME to the side MSC initiate co-location update request, MSC can not active initiation co-location update.One
Denier user must then be triggered because certain reason causes the MSC recorded in practical place MSC and HSS/HLR not to be consistent by MME
User re-starts co-location enrollment process.And in the prior art, since the side MSC usually can find that UE is practical earlier than MME
The MSC recorded in place MSC and HSS/HLR is not consistent, but MSC can not be handled voluntarily or be solved the problems, such as this, can only be first
The register information in user VLR is removed, then MME where then finding user contacts the side MME pressure UE again and re-registers
Solve the problems, such as this, above process intermediate link is more, processing delay is increased, if user carries out CSFB language again in the meantime
Sound call etc. can then again result in voice communication failure, seriously affect user experience.
For this purpose, the case where can only passively receiving location updating for MSC in the application, realize and connect by MSC by SGs
Mouth actively initiates co-location update.MSC can actively triggering supports the UE of CSFB to carry out in the case where not needing MME operation
Co-location renewal process, it is ensured that relevant register information is newest correct in timely fast refresh MME, MSC, HSS/HLR
Information, solve the problems, such as to support the MSC that records in HSS/HLR of user of CSFB not to be consistent with actual MSC, it is such to simplify solution
The step of problem, improves the speed and efficiency for solving problems, enhances the initiative of MSC.
It should be noted that HLR is set in 2G 3G mobile communication system, and HSS is set to 4G and its evolution moves
In dynamic communication system, effect of the two in the mobile communication system where respective is similar.
As shown in Figure 1, being the structural schematic diagram of co-location provided in an embodiment of the present invention more new system, including mobile friendship
Switching center9 MSC 11 and mobility management entity MME 12, in which:
The MSC 11, for determining that the HSS/HLR for storing itself (belongs to when needing to carry out co-location update
Client server/home location register) acknowledgement state be set to it is insincere, and to MME (mobility management entity) send combine
Position updating request；And the second co-location is executed according to the response message that the MME is returned and updates operation；
The MME 12 is used to update request according to the co-location and executes after the update of the first co-location operates to institute
State the response message of MSC return.
Preferably, being communicated between MSC and MME by SGs interface, SGs interface for realizing CSFB in the lte networks
Calling and the SMS function based on SGs.
When it is implemented, when MSC judgement needs to initiate by SGs interface when co-location updates request (for example, supporting
When being called CSFB call failure caused by the MSC difference that the UE of CSFB is recorded in the MSC and HSS/HLR because where practical, the side MSC can
Reason is quickly found in a manner of through signaling tracing etc., MSC, which can be determined that, as a result, needs to initiate co-location update request).
MSC the HSS/HLR acknowledgement state in the UE register information is set to first it is insincere, then generate an initiation CS (circuit domain)
Position updating request is simultaneously sent to MME by SGs interface.Wherein, it may include at least one in the request message that MSC is sent
IMSI (International Mobile SubscriberIdentification Number, international mobile subscriber identification
Code), IMSI can not also be carried.Wherein, if carrying IMSI in the request message that MSC is sent, MME needs are used to indicate
Location updating is carried out for the corresponding UE of IMSI of carrying, if not carrying IMSI, MME is used to indicate and needs for the MSC
Under the UE of all support CSFB function carry out location updating.
Based on this, whether carry the UE's in need for carrying out co-location update in the request message sent according to MSC
IMSI, co-location update provided in an embodiment of the present invention can have following two embodiment.
Co-location update need to be carried out by carrying at least one in the request message that the first embodiment, MSC are sent
The IMSI of UE.
Under this embodiment, MME first determines whether itself is stored with after the request message for receiving MSC transmission
Corresponding IMSI, if itself it is not stored have a corresponding IMSI, MME, which by SGs interface returns to co-location to MSC and updates, to be lost
Lose message.If itself being stored with corresponding IMSI, MME sends Location Update to MSC by SGs interface
Request (co-location update notification message) starts co-location and updates.The request message and the subsequent side CS complete bit
Renewal process is set, Location Update Accept (co-location update confirmation message) etc. is updated with existing co-location
Process is identical, and which is not described herein again.
MSC continues to complete subsequent operation according to the response message that MME is returned.Specifically, if MME returns to co-location more
New failure news, then MSC deletes the user registration information；If MME returns to Location Update Request message,
Then MSC notifies HSS/HLR to update the position area where the corresponding UE of corresponding IMSI, and modifies the HSS/HLR of itself storage
Acknowledgement state is credible.If MME does not have returning response message, MSC is without carrying out any operation.
The IMSI that need to carry out the UE of co-location update is not carried in the request message that second of embodiment, MSC are sent.
Under this embodiment, MME is for the UE of all support CSFB registered under the MSC for sending request message to MSC
It sends co-location update notification message and carries out co-location update.When it is implemented, MME can will send request message
The UE of all support CSFB registered under MSC is grouped, can also be by for example, MME can be grouped UE according to IMSI
UE is grouped according to subscriber signaling, the embodiment of the present invention, without limiting, is based on group result, asks in batches to transmission to this
It asks the UE of all support CSFB registered under the MSC of message to send co-location update notification message to MSC and carries out co-location
It updates.
When it is implemented, MME carries out the process and the first above-mentioned embodiment of co-location update for each group of UE
It is similar, that is, it is directed to each group of UE, MME sends Location Update Request (co-location to MSC to by SGs interface
Update notification message) start co-location update.The request message and the subsequent side CS full location renewal process,
Location Update Accept (co-location update confirmation message) etc. is identical as existing co-location more new technological process, this
In repeat no more.MSC notice HSS/HLR updates the position area where the corresponding UE of corresponding IMSI, and modifies the institute of itself storage
It is credible for stating HSS/HLR acknowledgement state.
The foregoing describe MSC actively to initiate the implementation process that co-location updates by SGs interface, is sent according to MSC
The IMSI that the UE that need to carry out co-location update whether is carried in request message is respectively processed.It need to be joined for carrying
The process for closing the IMSI of the UE of location updating is used to actively update the CS side position information of corresponding UE；It need to be into if do not carried
The IMSI for the UE that row co-location updates, then for whole support CSFB functions under MSC/VLR (home location register)
UE carries out co-location update, will trigger MME and carries out re-injection to the UE for all support CSFB functions of being associated with the MSC/VLR
Volume.
Co-location update method provided in an embodiment of the present invention increases MSC and actively carries out flag set, master to user
Dynamic CS location update request message, the MME of initiating carries out respective handling for the CS position updating request that MSC is sent, to realize MSC
Actively trigger the purpose that CSFB user carries out co-location.Find that CSFB user (supports to solve MSC in the prior art
The UE of CSFB function) it is practical where MSC and HSS/HLR in the MSC that records be not inconsistent, when notice MME carries out co-location update
The intermediate link passed through is more, when increasing CSFB user's MSC registration abnormity the problem of processing delay.
Based on the same inventive concept, a kind of joint bit implemented respectively by MSC and MME is additionally provided in the embodiment of the present invention
Update method and relevant device are set, since the principle that the above method and equipment solve the problems, such as is similar to co-location more new system,
Therefore the implementation of the above method and equipment may refer to the implementation of system, and overlaps will not be repeated.

After S22, MSC receive the MME according to co-location update request execution the first co-location update operation
The response message of return.
S23, MSC execute the second co-location according to the response message and update operation.
Optionally, co-location, which updates in request, carries the IMSI that need to carry out the user equipment (UE) of co-location update；
If correspondingly, including the MME in the response message that MME is returned when determining that itself is stored with the IMSI, for described
The co-location update notification message or the MME that the corresponding UE of IMSI is sent to MSC determine itself it is not stored have it is described
When IMSI, the co-location that Xiang Suoshu MSC is sent updates failed message.Based on this, in step S23, MSC receive it is described
When the co-location update notification message that MME is sent for the corresponding UE of the IMSI, then notify described in the HSS/HLR update
Position area where the corresponding UE of IMSI；And the HSS/HLR acknowledgement state for modifying itself storage is credible.If MSC connects

The MSC difference that is recorded in MSC and HSS/HLR because where practical of UE caused by when being called CSFB call failure, the side MSC can lead to
Cross the modes such as signaling tracing and quickly find reason, MSC, which can be determined that, as a result, needs to initiate co-location update request) it is sent out to MME
Co-location is sent to update request.
S32, MME are updated according to the co-location to be returned after request execution the first co-location update operates to the MSC
The response message returned.
If co-location updates the IMSI for carrying the UE that at least one need to carry out co-location update in request, walk
In rapid S32, MME first determines whether itself is stored with corresponding IMSI, if it is, IMSI pairs carried into request message
The UE answered sends co-location update notification message to MSC；If it is not, then sending co-location to the MSC for sending request message
Update failed message.If the co-location, which updates in request, does not carry the IMSI that need to carry out the UE of co-location update,
In step S32, MME sends co-location more to MSC for the UE of all support CSFB registered under the MSC for sending request message
New notification message carries out co-location update.
