Fig. 1 is the flow chart of base station switching handling method embodiment one of the present invention, and as shown in Figure 1, the method for present embodiment can comprise:

Step 101, determine to initiate the hand-off process flow process according to the metrical information of subscriber equipment.

UE can send metrical information to the source base station of its access, this metrical information can so that source base station determine whether and need carry out hand-off process UE.When source base station determined that according to this metrical information needs carry out hand-off process to UE, then source base station can be initiated the hand-off process flow process.For instance, source base station in the present embodiment can be for UE provide service Home eNodeB (Home eNB, hereinafter to be referred as: HeNB).

Step 102, determine can provide in the adjacent base station first target BS of first business, and described subscriber equipment is switched to described first target BS, described first business is the current business that offers described subscriber equipment.

In the present embodiment, source base station can with the data gateway that service is provided for UE (PacketGateway, hereinafter to be referred as: P-GW) connect, therefore, the service that this source base station can provide this P-GW to provide for UE.First business in the present embodiment is the business that this source base station can provide service for UE, also promptly provides service corresponding business with P-GW.When specific implementation, the business information of this first business can be the IP address of P-GW, perhaps identification information such as id information, present embodiment does not limit the concrete manifestation form of the business information of this first business, but can adopt the sign of first business that can identify this source base station arbitrarily, present embodiment does not limit the obtain manner of this sign yet, source base station HeNB both can be by the HeNB gateway (hereinafter to be referred as: HeNB-GW) or mobile management entity (Mobility Management Entity, hereinafter to be referred as: MME) obtain this sign, also can by gateway (hereinafter to be referred as: S-GW) obtain this sign.

Source base station can be according to the business information select target base station of this first business.Specifically, the base station under a network coverage can be for a plurality of, and these base stations can connect with different P-GW, and these P-GW can provide different business service, thereby the base station that feasible and different P-GW connect can provide different business service for UE.In these base stations, P-GW some or that certain some base station connects is identical with the P-GW of source base station connection, and therefore, this or these base station has identical professional ability with source base station, and these base stations promptly can be the target BS in the present embodiment.For instance, in the specific implementation process, each target BS all can be safeguarded an ability information table, can store in this ability information table its adjacent base station the business information that can provide.The source base station of the current access of UE can be determined and the current corresponding target BS of first business that provides for UE of this source base station according to this ability information table.In the present embodiment, so-called adjacent base station is meant the base station close with the source base station geographical position.

Need to prove, source base station according to this first professional target BS of determining can for one also can be for a plurality of, if the target BS of determining is one, then source base station can determine that this target BS is first target BS of the business continuance that can keep UE, then source base station can be initiated handoff process, UE is switched to this first target BS of determining, if it is a plurality of that the target BS of determining has, then source base station can select a target BS to initiate handoff process as first target BS from these target BS.The method of selection first target BS can adopt the any-mode of prior art from a plurality of target BS, for example select signal is the strongest in a plurality of target BS base station as first target BS, the base station of perhaps selecting load minimum in a plurality of target BS repeats no more as first target BS.Because source base station is being selected for UE in the process of first target BS, taken into full account the current home server that connects of UE, thereby after making that UE switches to first target BS from source base station, UE can also continue to use this business, and the problem of service disconnection can not occur.

In the present embodiment, base-station gateway can be under the triggering of OAM entity, the business information of collecting is sent to source base station and its adjacent base station, perhaps indicate the mutual business information separately of source base station and its adjacent base station, thereby make that source base station can be before initiate switching UE, obtain the business information of adjacent base station of this source base station and the corresponding relation between the adjacent base station.When UE is switched, can inquire about this corresponding relation, determine that source base station is from first professional definite first target BS that service is provided as UE, make first target BS of determining also can provide and this first professional corresponding service service, thereby after making that UE switches to first target BS, this first target BS can continue as UE and provide and this first professional corresponding service service, avoids occurring the phenomenon of service disconnection.

Fig. 7 is the flow chart of base station switching handling method embodiment six of the present invention, and as shown in Figure 7, the method for present embodiment can comprise:

Step 601, determine to initiate the hand-off process flow process according to the metrical information of subscriber equipment.

The step 601 of present embodiment is similar with the realization principle of step 101 shown in Figure 1, repeats no more herein.

Above-mentioned base station switching handling method all is before UE is carried out hand-off process, and source base station has promptly obtained the business information of adjacent base station, to guarantee follow-up when UE is carried out hand-off process, can guarantee that UE uses professional continuity.In the present embodiment, source base station does not need to know in advance the business information of adjacent base station, but UE is being carried out in the process of hand-off process, trial switches to some target BS with UE, and the business information of the feedback by this base station judges whether to determine that UE is switched to this target BS uses professional continuity to guarantee UE.

Step 602, a source base station target BS in adjacent base station sends the first handoff request message, and described first handoff request message contains the business information of described first business.

Specifically, source base station can send the first handoff request message to one of them target BS of a plurality of adjacent base stations, can comprise the business information of first business of this source base station in this first handoff request message.This adjacent base station that receives the first handoff request message can be known the business information of source base station according to the business information of this first business, also is which P-GW the service that source base station provides for UE is.

Step 603, this target BS judge whether to possess the professional ability identical with the business information of first business, if then execution in step 604, otherwise execution in step 602.

This target BS can determine whether himself can provide the identical business service that offers UE with source base station for UE according to the business information of this first business.If the P-GW that this target BS has the ability to be connected with source base station links to each other, then this target BS can feed back the handover success response message to source base station, if the P-GW that this target BS can not be connected with source base station connects, then this target BS can feed back the handoff failure response message to source base station.

Step 604, this target BS send the handover success response message to source base station, and this source base station switches to this target BS with UE.

In the present embodiment, this target BS is first target BS that source base station is determined, also promptly can guarantee the target BS of UE business continuance.

After source base station switched to UE the first definite target BS of step 604, the business continuance that this UE uses can guarantee.

Source base station carries out above-mentioned steps 602 again and 603 other target BS of attempting in adjacent base station send the first handoff request message, up to UE being switched to first target BS that has identical services information with source base station.

For instance, the source base station HeNB A among Fig. 2 can send the first handoff request message to HeNB B earlier, can carry the business information of P-GW B in this request message, for example IP address information etc.HeNB B has the ability to be connected with P-GW A, therefore, HeNB B can determine the business information of himself, it can not provide business service based on P-GW B for UE, therefore, this HeNB B sends the handoff failure response message to source base station HeNBA, HeNB A sends the first handoff request message to HeNB C more then, can carry the IP address information of P-GW B in this request message, HeNB C can be connected with P-GW B, therefore, HeNB C can determine the business information of himself, it can be for UE provides business service based on P-GW B, and therefore, this HeNB C sends the handover success response message to source base station HeNB A.Source base station HeNB A can switch to UE HeNB C after receiving this handover success response message.Therefore, UE can continue to use the business service based on P-GW B, and service disconnection can not occur after switching to HeNB C.

Need to prove, in the present embodiment, what source base station adopted is the business information of polling mode inquiry adjacent base station, but present embodiment does not limit source base station which target BS transmission handoff request message in adjacent base station earlier, and the back sends handoff request message to which target BS.

Replacedly, in order to guarantee to reduce handoff delay, in the present embodiment, source base station also can send the first handoff request message to adjacent base station simultaneously, and described first handoff request message contains the business information of described first business; And the switching response message of receiving neighbor bs feedback, source base station can determine that the base station of the handover success response message correspondence in the switching response message is first base station, therefore this first base station is the target BS that can guarantee the business continuance of UE after switching, this first base station both can be a target BS, also can be a plurality of target BS; Then, this source base station switches to first target BS in described first base station with described subscriber equipment.Those skilled in the art can adopt prior art to select first target BS that UE is carried out hand-off process from least one first base station, for example select the base station of load minimum etc.

Replacedly, described basis is determined first target BS for described subscriber equipment provides first business of service, and comprising: send the first handoff request message to adjacent base station, described first handoff request message contains the business information of described first business; Receive the handover success response message of at least one first base station feedback in the described adjacent base station, described first base station has corresponding with the business information of described first business user's group number of closing; From described at least one first base station, determine first target BS.By this method, source HeNB can select the base station consistent with the CSG-ID of the source HeNB that local service is provided as first target BS that switches when UE is carried out hand-off process.
