Mutually can be combined.
Embodiment one
Fig. 5 applies to the locality connection that user sets up from source base station from home, subsequently moves to which as position there occurs
His base station or base station from home.
The present embodiment is applied to terminal and accesses EPC from GERAN/UTRAN/EUTRAN（EPS core nets）Or GPRS network.
If UE is accessed from GERAN/UTRAN, base station from home is HNB, and base station is BSS or NodeB/RNC, and mobile management unit is
SGSN.If UE is accessed from EUTRAN, base station from home is HeNB, and base station is eNB, and mobile management unit is MME.If for
SGSN connects the framework of local gateway by Gn/Gp interfaces, then without SGW in this flow process, all message through SGW are all not required to
Will be through SGW, but mobile management unit is transmitted directly to local gateway.For the scene of base station from home, may deposit in network
In home base-station gateway, if there is home base-station gateway, then the message between all base station from home and mobile management unit
It is required for through home base-station gateway.Further message between base station from home and local gateway, can pass through base station from home
Gateway can not also pass through home base-station gateway.For the scene for forwarding message by home base-station gateway, home base-station gateway
Transparent transmission is carried out to the message that passes through, the process of transparent transmission is unrelated to the invention, does not repeat here.
The present embodiment is applied to base station from home and local gateway the situation of control plane signaling.As shown in figure 5, the present embodiment
Flow process mainly comprises the steps：
Step 501, UE positions change, and source base station from home is detected up to handoff threshold, then obtain close region to UE
Wireless measurement report.Source base station from home reports selection target base station according to the wireless measurement that UE is reported, and to mobile management list
Unit sends handover request.
Step 502, mobile management unit judge whether user has local service, if without local service, application is existing
There is technology, not in the limit of consideration of the present invention；If UE sets up local service, need to judge target according to subscription data
Whether the information of base station allows to set up locality connection in target BS, and judges local service whether unique PDN of user
（packet data network）Connection, the i.e. user do not have core network PDN to connect.The packet of target BS contains but does not limit
In one below or its any combination：The CSG information of target BS, target BS access module information（Closed mode, open mould
Formula, or mixed mode）, the Base Station Identification of target BS, the cell ID of Target cell.Wherein, wrap in user signing contract information
Whether the corresponding relation containing APN and CSG, i.e., allow user to set up the locally-attached corresponding pass of specific APN in some CSG
System.
Step 503, if according to the judgement of step 502, it is allowed to set up locality connection in target BS, then executes switching
Subsequent process, subsequent process similarly to the prior art, are not repeated here.
Step 503a, if according to the judgement of step 502, setting up locality connection not in Target cell, then also needing to
Determine whether that whether locality connection is that unique PDN of UE connects if it is, execution step 504a ~ 506a；Otherwise, step is executed
Rapid 504b ~ 510b；
Step 504a, mobile management unit return switching to source base station from home and prepare failed message, wherein carry and unsuccessfully refer to
Show, indicate that failure cause does not support local service for target side.The instruction can pass through to extend existing cause value IE
（Information Element）Value, or increase new IE to realize.
Step 505a, source base station from home are cell that UE selects that other can switch, and send out again according to configured information
Handover request is played to mobile management unit, starts to execute from step 501.And can not for the UE by the cell ID of handoff failure
The cell of switching.
Step 506a, if source base station from home finds do not have other available cells that can switch, terminates switching and tastes
Examination.The release of radio bearer is initiated after wireless signal reaches threshold value.
Step 503b, if according to the judgement of step 502, judging to connect with setting up not in Target cell, and entering one
Step judges that locality connection is not unique PDN connections of UE, then execution step 504b ~ 510b.
Step 504b, mobile management unit return switching to source base station from home and prepare failed message, wherein carry and unsuccessfully refer to
Show, indicate that failure cause does not support local service for target side.
Wherein, the failure reason value in above-mentioned steps 504a and step 504b can be identical value, or difference takes
Value.
Specifically, if source base station from home is when locality connection is set up, it is locality connection to have learned which carries
Related carrying, then the reason for failing value is can be with identical.Source base station from home after above-mentioned cause value is received, according to this
Ground judges that whether locality connection is uniquely coupled judging to continue executing with a processes or b processes.
If source base station from home cannot know which carries the reason for being the related carrying of locality connection, above-mentioned failure and is worth
It is different values to need.So, source base station from home can according to the reason for difference value instruction judging to continue executing with a processes also
It is b processes.
Above-mentioned identical or different the reason for, value can pass through to extend existing cause value IE（Information
Element）Value, it is also possible to realized by increasing new IE.
When it is uniquely coupled that mobile management unit judges, cause value can be in the following way：
Cause value one（cause1）Represent that target side does not support local service；In step 504b, extension can be carried
Cause value two, the cause value two represent that target side does not support local service, while it is not that user uniquely connects to be also represented by locality connection
Connect；And in step 504a, original cause value one can be carried, it is also possible to the reason for carrying extension value three, the cause value three
Represent that target side does not support local service, while it is that user is uniquely coupled to be also represented by locality connection, etc..
Or, above-mentioned steps 504a are identical value with the failure reason value in step 504b, and mobile management unit exists
The switching of return prepares in addition to increase whether locality connection is the uniquely coupled instruction of user in failed message, so as to source family expenses base
Stand and can indicate that judgement continues executing with a processes or b processes according to the increase.
Step 505b, mobile management unit are sent to local gateway by SGW and delete session request, are wherein carried and are locally connected
Connect default bearing/main PDP Context mark.
Step 506b, local gateway are deleted locally-attached relevant bearer and are all deleted, and by SGW to mobile management unit
Send and delete conversational response.
Step 507b, local gateway send deleting bearing request to source base station from home.If locality connection has multiple carryings,
So the request is required to all delete these carryings.Now source base station from home can send multiple deleting bearing requests, or
Person deletes these carryings in a piece of news simultaneously.
Step 508b, source base station from home return deleting bearing response to local gateway.
Step 509b, source base station from home according to value the reason in step 504b and/or are not uniquely coupled configured informations,
HO flow process is initiated again wouldn't, until initiating the switching flow of target BS after step 507b deleting bearing again.
Step 510b, executes the subsequent process of switching, and subsequent process similarly to the prior art, is not repeated here.
