Wherein, the co-location area updates the IMSI and GUTI (Globally Unique Temporary Identifier, global unique temporary identity) that user equipment is contained in request message.
Secondly, MME according to the GUTI of the user equipment to report identify, judge the user equipment whether can on current MME registration/updating.
Specifically, if MME determines to receive user equipment TAU request, a tracking area identification is returned to user equipment in TAU accept message（ TAI , Tracking Area Identity ).
In addition, MME is before TAU accept message is sent, updates and ask to MSC launch positions area instead of the user equipment, MSC is according to the IMSI of the user equipment to its Visited Location Registor（VLR, Visited Location Register) initiate registration and inquiry notice.
Now confirm whether the user equipment is registered in the VLR by VLR, when it is determined that the user equipment is registered in the VLR, directly feed back registration and inquiry object information to the MSC；When it is determined that the user equipment is not yet registered in the VLR, according to the IMSI of the user equipment, the home location register belonged to the user equipment（HLR, Home Location Register) inquiry request is initiated, and the Query Result information of HLR returns is received, give the MSC by the Query Result feedback of the information received.
Wherein, the signing information of user equipment is contained in Query Result information, the signing information is used for the MSC and judges whether to receive the location area updating request of the user equipment.
MSC is according to the Query Result information received, it is determined whether respond location area updating request.When MSC determines that the location area updating for receiving the user equipment is asked according to Query Result information, return to a present position-region to MME and identify LAI, and user equipment is sent in TAU Accept message by MME.
There is illustrated the flow that user equipment obtains LAI, after user equipment initiates CS service call requests in LTE cells, during performing CSFB flows, once find the target of user equipment gravity treatment
When the LAI that the LAI of 2G/3G cells is obtained with the user equipment is differed, above-mentioned location area updating flow will be first carried out, and after location area updating flow is finished, then CSFB flows are performed, there is delay problem which results in CSFB flows.
Each embodiment of the present invention is described in detail with reference to Figure of description.

It is a kind of schematic flow sheet of the method for business processing that the embodiment of the present invention one is provided as shown in Fig. 1.Methods described can be as described below.
Step 101:Base station obtains the LAI of user equipment.
In a step 101, base station receives the CS service call requests that user equipment is sent, and send the CS service call requests to MME before the LAI of user equipment is obtained.
The CS service call requests pass through expansion service message（Extended Service Request) carrying transmission.
Wherein, type of call instruction is carried in the CS service call requests, the type of call is designated as CSFB type of calls.
Specifically, the LAI of base station acquisition user equipment mode includes but is not limited to following several：First way：
The CS service call requests that user equipment is sent are received, the CS service call requests include the LAI of user equipment.
This mode be user equipment obtain MSC for its distribution LAI when, be stored in that user equipment is local so that user equipment carries the LAI preserved when sending CS service call requests.
The second way：
Base station is according to the tracking area identification of user equipment（TAI, Tracking Area Identity) corresponding relation between default TAI and LAI, determine the LAI of the user equipment.
It is pointed out that the TAI of user equipment is identical with the TAI for the LTE cells that the user equipment is accessed, and the TAI of the LTE cells of user equipment access is preserved in base station.
When base station receives the CS service call requests of user equipment transmission, the TAI for the LTE cells that can be accessed according to user equipment determines the TAI of user equipment.
The third mode：The LAI of the user equipment is obtained at MME, it is described in detail below：Base station receives the CS service call requests that user equipment is sent, and sends the CS service call requests to MME；Receive the customer equipment context modification request that MME is sent（UE Context
Modification Request) message, wherein, the LAI of user equipment is carried in UE Context Modification Request message;
Base station determines the LAI of user equipment according to UE Context Modification Request message.It should be noted that MSC distributes to user equipment when the LAI that UE Context Modification Request message is carried is user equipment launch position registration/updating flow, MME is saved it in locally.
Step 102:Base station obtains the LAI of the target 2G/3G cells of user equipment.
In a step 102, the LAI of the target 2G/3G cells of base station acquisition user equipment mode includes but is not limited to：
First way：
Base station receives the metrical information of user equipment to report, wherein, the mark i of target 2G/3G cells is contained in metrical information only；
Base station receives the system information of target 2G/3G cells according to the mark of target 2G/3G cells, wherein, system information carries the LAI of target 2G/3G cells.
The second way：
Base station is according to default LTE cells and performs the LTE cells that corresponding relation and user equipment between the 2G/3G cells that CSFB is operated are accessed, and determines the target 2G/3G cells of user equipment；
Base station receives the system information of target 2G/3G cells, wherein, system information carries the LAI of target 2G/3G cells.
It is pointed out that the mode that base station receives the system information of target 2G/3G cells includes but is not limited to：
Base station utilizes RIM (RAN Information Management) flow, and the system information of target 2G/3G cells is received by the control device of the target 2G/3G cells of user equipment.
Specifically, base station sends request message to target 2G/3G cells, wherein, request message is used to obtain
Take the system information of target 2G/3G cells；And receive the system information of target 2G/3G cells transmission.It should be noted that 2G/3G cells include but is not limited to：Support GSM (Global System for Mobile communication, global system for mobile communications）The cell of network formats, support TD-SCDMA (Time Division Synchronized Code Division Multiple Access, time division synchronous CDMA systems）The cell of network formats, support WCDMA (Wide-band Code Division Multiple Access, WCDMA access system）The cell of network formats, support CDMA (Code Division Multiple Addressing, CDMA）The cells of network formats, the one or more supported in the cells of CDMA2000 network formats.
Wherein, system information can also include the relevant informations such as mark, the frequency of target 2G/3G cells in addition to the Location Area Identification LAI comprising target 2G/3G cells.
For example：The system information for the GSM cell that base station is obtained by RIM flows, for example, SI (System Information, system information）1st, SI3 and SI 13, wherein, the Location Area Identification LAI of the GSM cell is included in SI13.
Step 103:The LAI of user equipment is carried when it is determined that the LAI of the user equipment and LAI of target 2G/3G cells is differed and is sent to user equipment in the system information of target 2G/3G cells by base station.
Wherein, system information can be carried and be sent to user equipment in instruction message is fallen after rise by base station, can also be system information carrying user equipment is sent in other message, do not limit herein.
For example, the CS service call request message is sent to MME by base station after the CS service call requests of user equipment are received, MME, which is received, sends CSFB operation instructions to base station after the CS service call request message, base station, which sends to fall after rise, indicates message to user equipment to indicate that UE carries out falling operation, and the falling indicates that message carries the system message in step 103.
Wherein, CSFB operation instructions are carried to base station by UE Context Modification Request message, do not limit herein.
In step 103, the scope of a MSC covering is divided into multiple position areas（Refer to geographical position area）Each position area is identified by a unique LAI, and the serving cell included in each position area includes but is not limited to one, the problem of signal of communication that there are different network formats repeats to be covered in a region, also implies that the corresponding Location Area Identification LAI identicals of serving cell of different network systems
Situation, present invention is generally directed to the situation that the corresponding Location Area Identification LAI of the serving cell of different network systems is differed.
Generally, MSC is in order to the timely positional information for obtaining user equipment, user equipment execution position when across different LAI is needed to update operation, this means that, when user equipment is fallen after rise to 2G/3G cells from LTE cells, it may need to carry out location updating, here it is causing the longer basic reason of CSFB flow times.
Specifically, before user equipment initiates CSFB flows, whether it is same MSC that base station needs to confirm as user equipment distribution LAI moving exchanging center MSC with the MSC that the target 2G/3G cells that the user equipment performs CSFB operations are connected, or, belong to same MSC ponds, if not same MSC and being not belonging to same MSC ponds, the subsequent operation of the present invention is not performed then, the MSC connected by target 2G/3G cells is needed to redistribute LAI, execution position more new technological process for user equipment.
This confirmation process can be preset in the network planning, or notify whether base station can change to perform this operation by NMS, be not limited here.
The MSC being connected in the MSC and the user equipment for being defined as user equipment distribution LAI the target 2G/3G cells for performing CSFB operations is same MSC, or, when belonging to same MSC ponds, determine whether whether the LAI of user equipment is identical with the LAI of target 2G/3G cells.
When it is determined that the LAI of the user equipment and LAI of target 2G/3G cells is differed, the LAI of user equipment is carried and is sent to user equipment in target 2G/3G cell system informations.
It should be noted that, target 2G/3G cell system informations are sent to user equipment by base station, by user equipment judge perform CSFB flows target 2G/3G cells LAI and user equipment LAI it is whether identical, if differing, treat that user equipment is reselected to after target 2G/3G cells, launch position more new technological process；If identical, user equipment is reselected to after target 2G/3G cells, no longer launch position area more new technological process, directly initiates voice call service.
