The specific embodiment of the invention provides a kind of method of setting up local exchange, and this method comprises: after the selected target base station, carry out step as shown in Figure 1:
Step 101: local exchange is set up in the indicating target base station in handoff procedure;
In step 101, after having selected target BS, local exchange is set up in base station controller indicating target base station in handoff procedure, for example, can realize in the following manner: base station controller activates message to the target BS transmitting channel, and activates the indication information element that carries the local exchange of both call sides foundation in the message at this channel, like this, after can making target BS receive this channel activation message, when switching, also carry out the foundation of local exchange.
Step 102: the notice of the local exchange of successful foundation of local exchange back transmission is successfully set up in the receiving target base station in handoff procedure;
Receive the channel activation message that carries the indication information element of setting up local exchange of base station controller transmission at target BS after, target BS can activate the indication of message according to this channel, when switching, directly carry out the foundation of local exchange, and need not after switching is finished, receive the local indication that exchanges of foundation that base station controller sends again, to carry out the foundation of local exchange.After successfully setting up local exchange, target BS exchanges the message of successfully setting up with this locality and informs base station controller, at this, can realize in the following way: because in the present embodiment, target BS is to set up local exchange in handoff procedure, therefore, when informing that the local exchange of base station controller is successfully set up, can adopt and in handoff completion message, carry the mode of successfully setting up local cell-switching and realize.Like this, base station controller can carry expression by reception and successfully sets up the handoff completion message of local cell-switching and know that local exchange successfully sets up.
Step 103: send local exchange has been set up in expression under target BS message to mobile switching centre.
Because in the present embodiment, local exchange is set up in handoff procedure, then base station controller sends to switch to mobile switching centre and carries out message, and in this message, carry local exchange has been set up in expression under target BS cell, can realize that like this mobile switching centre knows that correspondent set up local exchange under a certain base station.
Except above-mentioned steps, also can comprise: the transfer resource that discharges the corresponding Abis interface user of the correspondent face of having set up local exchange.
After the exchange of this locality, owing to need not to pass through base station controller with the data between the correspondent of setting up local exchange, then this moment, base station controller can discharge the transfer resource with the corresponding Abis interface user of this correspondent face again.
Correspondingly, movements control center also can corresponding release and the transfer resource of setting up the local corresponding A interface user plane of correspondent that exchanges.

In this simultaneously, BSC also needs the ID that can set up the local both call sides branch that exchanges to inform BTS2.
Step 203:BTS2 activates entrained cell in the message according to received channel, judges that whether this locality exchange between MS1 and the MS2 can set up, and judged result is informed BSC.
In step 203, after BTS2 receives the channel activation message of BSC transmission, indication information element according to the local exchange of foundation entrained in this message judges whether to set up local exchange, if judged result is represented and can be set up, then activate the feedback message of message to the BSC transmitting channel, and in this message, carry expression and can in calling out handoff procedure, set up the cell of local exchange, and enter step 204; If judged result represents and can't set up, then need in the feedback message that activates message to the BSC transmitting channel, carry expression and can't in calling out handoff procedure, set up the cell of local exchange, then follow-up needs are called out switching and are got final product.
Step 204:BSC sends switching command to MS1 after the channel that receives the BTS2 transmission activates the feedback message of message.
Step 205:MS1 is behind the switching command that receives the BSC transmission, in incision BTS2 such as the specified dedicated channel configuration of switching command.
So far step, MS1 has cut BTS2.
The local loopback operation is carried out in calling between the MS1 of step 206:BTS2 and the MS2, sets up this locality exchange between MS1 and the MS2.
Because BTS2 has determined the calling between MS1 and the MS2 and can set up local exchange when setting up the calling switching, therefore, after MS1 incision BTS2, the local loopback operation is carried out in the calling between the MS1 of BTS2 and the MS2, thereby realizes the foundation of this locality exchange between MS1 and the MS2.
Step 207:BTS2 sends to BSC and switches the message of finishing, and carries the local exchange of expression and whether set up successful cell in this message.
In step 207, the message that BTS2 finishes to the switching that BSC sends, the cell that carries in this message is represented the local successfully foundation that exchanges, and then enters step 208; If local exchange foundation failure (for example, BTS2 internal error occurs in carrying out local swap operation), then the cell that carries in this message is informed the local exchange foundation of BSC failure.
Step 208:BSC sends to switch to MSC and carries out message, and carries in this message and represent that MS1 and MS2 have set up the cell of local exchange under BTS2.Otherwise, need not to do specified otherwise.
In step 208, BSC carries out message by sending to MSC to switch, inform that MSC has sent inner switching in this BSC territory, owing to also carry expression MS1 and MS2 have set up local exchange under BTS2 cell in this message, therefore, BSC also can inform this locality exchange that MSC sets up and the type of local exchange after switching, still BTS bunch of local exchange etc. of the local exchange of BTS in this way.
Meanwhile, BSC will discharge the transfer resource of MS1 calling branch and the corresponding Abis interface of MS2 calling branch.
In addition, MSC also after receiving switching execution message, learns that MS1 and MS2 have set up local exchange, the corresponding transfer resource that can discharge these two calling branch institute corresponding A interface user planes.
