For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Fig. 1 is the flow chart of an embodiment of service distributing processing method of the present invention, and as shown in Figure 1, the method for present embodiment can comprise:
The PS business request information that step 101, reception subscriber equipment send.
The identification information that comprises described subscriber equipment in the one PS business request information.
Base station equipment can receive the PS business request information that UE sends.For instance, this base station equipment can for femto cell (hereinafter to be referred as: the femto base station), this femto base station can be laid between UE and the network side, it can pass through Service Gateway (Service Gateway, hereinafter to be referred as: SGW) communicate by letter with equipment of the core network, communicate by letter with internet device by the Gi interface.
Specifically, the UE of present embodiment can comprise mobility UE and non-moving property UE, wherein can may there be mobile equipment in the region in mobility UE for mobile phone etc., and non-moving property UE can not exist mobile or mobility small device for data card etc. on the region.When UE need carry out PS territory professional, it can send a PS business request information to the femto base station, the identification information that can comprise the UE of request PS territory business in this message, this identification information can be device number, international mobile subscriber identity (the International Mobile Subscriber Identity of this UE, hereinafter to be referred as: IMSI) etc., present embodiment does not limit the form of the identification information of this UE, as long as it will be appreciated by persons skilled in the art that can this UE of unique identification information all can be used as this identification information.
For instance, can store the corresponding relation between the type information of the identification information of UE and UE in the femto base station, for example adopt the form of tabulation, wherein the identification information of UE as mentioned above, and the type information of UE can adopt arbitrary form to represent, for example type information is " 1 ", and representing this UE is mobility UE, type information is " 2 ", and then representing this UE is non-moving property UE.It will be appreciated by persons skilled in the art that present embodiment does not limit the concrete manifestation form of type information, and present embodiment does not limit the type information yet and only can distinguish mobility UE and non-moving property UE.
When specific implementation, the femto base station can be known the type information of the UE of a certain identification information correspondence in advance, for example UE reports automatically, perhaps obtains from the CAMEL-Subscription-Information of UE, and present embodiment does not need to limit the specific implementation that the type information of UE is known in the femto base station.After the femto base station receives the PS business request information that UE sends and come, can obtain the type information of this UE according to the identification information of the UE that comprises in this request.For instance, if identification information and the corresponding type information of the form storage UE of tabulation are adopted in the femto base station, then the mode of tabling look-up can be adopted in the femto base station, finds the type information corresponding with the identification information of UE, thereby determines that this UE is mobility UE or non-moving property UE.
For instance, if the femto base station determines that according to type information the UE of transmission the one PS business request information is mobility UE, then the femto base station sends to equipment of the core network with a PS business request information, for example by SGW the one PS business request information is sent to equipment of the core network, thereby by equipment of the core network visit internet device.For instance, equipment of the core network in the present embodiment can be Gateway GPRS Support Node (Gateway GPRS Support Node, hereinafter to be referred as: network element that can the deal with data business in the core net such as GGSN), this internet device can be the Internet application server etc., and present embodiment does not limit equipment of the core network and which network element is internet device specifically adopt.
Specifically, the Gi mouth of prior art shunting scheme is only distinguished at CS business and PS business.For the non-moving property of this class of data card UE, the service request of its initiation is the PS business only generally, and for this class mobility of mobile phone UE, it both may initiate the PS business, also may initiate the CS business.Therefore, prior art is no matter the type of UE is mobility UE or non-moving property UE, as long as what initiate is the CS service request, base station equipment just sends to equipment of the core network with this CS service request, as long as what initiate is the PS service request, base station equipment just directly sends to internet device by the Gi interface with this PS service request.But for this class mobility of mobile phone UE, it the process that switch the base station occurs often when adopting Gi interface connection internet device to carry out the PS business.Switch aim base station may not have the Gi interface, even perhaps have the Gi interface, its port numbers and IP address all are different from port numbers and the IP address of the Gi interface of the source base station before switching.But, this moment internet device also constantly to the Gi interface corresponding port of source base station number and IP address transmission data, therefore, after switch the base station, this class mobility of mobile phone UE can't receive any PS business datum from internet device, thereby cause the PS service disconnection.And, the partial service of this class mobility of mobile phone UE, for example instant messaging service, MMS etc., its source address can only be Gateway GPRS Support Node (the Gateway GPRS Support Node in the core net, hereinafter to be referred as: GGSN) address ability access service server, therefore, for this class PS business, existing Gi mouth shunting scheme can't realize at all.
By contrast, in the present embodiment, base station equipment, for example the femto base station is determining that according to the type information of UE UE is mobility UE, when for example determining to be mobile phone, the femto base station not for another example the Gi mouth of prior art shunting scheme the one PS business request information is sent to internet device by the Gi mouth, but a PS business request information is sent to equipment of the core network.Hence one can see that, adopt the scheme of present embodiment, for the non-moving property of this class of data card UE, do not have any change, it can also continue to adopt existing Gi mouth shunting scheme to carry out the PS service distributing, namely by Gi interface accessing internet device, and for this class mobility of mobile phone UE, its CS business also can adopt existing Gi mouth shunting scheme, namely realize the CS business by core net, just when this class mobility of mobile phone UE initiated the PS business, the femto base station no longer adopted existing Gi mouth shunting scheme to make mobile phone pass through Gi interface accessing internet device, but makes mobile phone realize the PS business by core net.This shows, the service request that the femto base station can be initiated this class mobility of mobile phone UE again is that PS business or CS business are distinguished, so long as the service request that this class mobility of mobile phone UE initiates, femto all mails to equipment of the core network with service request in the base station.Therefore, even this class mobility of mobile phone UE moves because of the region in the process of using the PS business and switches, because its PS is professional irrelevant with the Gi interface, its needs carry out the position renewal and get final product in core net, therefore can not have influence on the continuity that this class mobility of mobile phone UE uses the PS business.
In the present embodiment, base station equipment is distinguished by the type to the UE that sends the PS business request information, make the PS service request of mobility UE no longer pass through Gi interface accessing internet device, but realize the PS business by equipment of the core network, thereby avoided mobility UE problem because of the mobile PS service disconnection that occurs in carrying out the PS business procedure.And, mail to equipment of the core network just because of the PS business request information with this class mobility of mobile phone UE, thereby realize MMS, instant messaging service etc. on the mobile phone.
Fig. 2 is the signaling process figure of another embodiment of service distributing processing method of the present invention, and as shown in Figure 2, present embodiment is that mobility UE is that example describes with femto base station and the UE with Gi interface, and the method for present embodiment can comprise:

Before this, UE and femto base station can be carried out radio resource control (Radio ResourceControl is hereinafter to be referred as the process that RRC) connects.
This step can be the step that this UE carries out when communicating with the femto base station for the first time.
Step 202, femto base station send CS service paging message to UE.
This CS service paging message is the test post that the femto base station sends when surveying the type information of this UE.
Step 203, UE send the CS page-response message to the femto base station.
Because this class mobility base station of mobile phone is opened the professional and PS business of CS simultaneously, and the PS business is only opened in the non-moving property of this class of data card base station.Based on this difference, when UE initiated the PS service request, the CS paging can be carried out to UE earlier in the femto base station.Therefore, the non-moving property of this class of the data card UE that does not open the CS business can not respond the CS service paging message that the femto base station sends, this class mobility of the mobile phone UE that opens the CS business then can respond CS service paging message, therefore, in a single day the femto base station receives the CS page-response message of UE feedback, can know that this UE is this class mobility of mobile phone UE, thereby detect the type information of UE.The identification information that can also comprise this UE in this CS page-response message, for example IMSI of mobile phone.
The identification information of this UE and the corresponding relation of type information are recorded in step 204, femto base station.
Process and the similar process of aforesaid operations, the femto base station can detect the type information of numerous UE.
Need to prove that the identification information of UE and the corresponding relation of type information also can not stored in the femto base station, and only store the identification information of mobility UE.
In addition, when the femto base station waits receives the CS page-response message of UE transmission, the femto base station also can start timer, the record page response stand-by period, if in the stand-by period, received the CS page-response message of UE feedback, can know that this UE is this class mobility of mobile phone UE, if also do not receive the CS page-response message of this UE feedback after overtime in the stand-by period, can know that then this UE is the non-moving property of this class of data card UE, thereby avoid the femto base station to wait for the CS page-response message that receives the UE feedback always.
Step 205, UE send a PS business request information to the femto base station.
The identification information that comprises this UE in the one PS business request information.
Step 206, femto base station determine that according to this identification information this UE is mobility UE.
