The method of setting up local exchange that the embodiment of the invention provides, initiatively initiate the local exchange request by BSS, so that the local exchange initiation is more timely, solved prior art because MSC can't know that the transfer resource of BSS side takies situation, cause by MSC and initiate the untimely problem of local exchange; The method that the embodiment of the invention provides can send local exchange to BSS and set up message, indicate described BSS describedly to satisfy the calling of local exchange condition to setting up local exchange by this message, so that this method can be to the calling of setting up local exchange to controlling, solved prior art and initiated by BSC and set up local exchange, the problem that causes MSC to control the calling of setting up local exchange.The technical scheme that the embodiment of the invention provides can in time exchange setting up this locality for the calling of satisfying local give-and-take conditions among the BSS under the control of MSC.
In order to make those skilled in the art can more be expressly understood the technical scheme that the embodiment of the invention provides, below by specific embodiment, the local method that exchanges of foundation that the embodiment of the invention is provided is elaborated.
As shown in Figure 3, the method for the local exchange of the foundation that another embodiment of the present invention provides comprises:
Step 301, BSS need to determine whether application to set up local exchange.
In the present embodiment, described BSS can determine whether the local exchange of needs application foundation according to the user mode of transfer resource, for example: if BSS judges BSC and base station (Base Transceiver Station, user's face transfer resource anxiety of the A interface between Abis interface BTS) or BSC and the MSC need then to determine application to set up local exchange; Also can set up according to the exchange of this locality of setting in advance and determine whether that needs set up local exchange requisition cycle, for example: set up when arriving requisition cycle when this locality exchange that sets in advance, then BSS need to determine application to set up local exchange; Certainly, in the use of reality, BSS can also determine whether to need to set up local exchange by other modes, every kind of situation is not given unnecessary details one by one herein.
Step 302, if need application to set up local exchange, BSS sends the local exchange request message to MSC.
In the present embodiment, described step 302 specifically can send local exchange request (Local Switch Required) message to MSC by the BSC among the BSS, wherein, described local exchange request message can be connectionless signaling connection control protocol (Signaling Connection Control Part, SCCP) message, the relevant informations such as sign that this this locality exchange request message can carry described BSS.
Step 303, MSC receives the local exchange request message that BSS sends.
Step 304, the local exchange request message that MSC receives according to step 303, it is right to obtain the calling of satisfying the local exchange condition from the calling centering of described BSS.
In the present embodiment, the relevant informations such as sign of the BSS that MSC can carry according to described local exchange request message determine that needs set up the BSS of local exchange, and by consisting of the calling of session to the cell ID (Cell-ID) at place among the described BSS of record, in conjunction with the encoding and decoding of calling out using, and current service condition etc. determines that whether calling among the described BSS to satisfying the local exchange condition.For example: if it is identical to consist of the right Cell-ID of the calling of session among the BSS, the right code encoding/decoding mode of described calling is identical, and does not carry out between the call other supplementary services, and then described MSC determines that described calling is to satisfying the local exchange condition; For another example: if it is identical to consist of the right Cell-ID of the calling of session among the BSS, the code encoding/decoding mode difference that described calling is right, and do not carry out between the call other supplementary services, then described MSC determines, if transcoder (Transcoder, TC) is positioned at the BSS side physically, then described calling is to satisfying the local exchange condition, otherwise, do not satisfy local give-and-take conditions.
Certainly, in the use procedure of reality, described MSC can also determine by other means that calling among the described BSS to whether satisfying the local exchange condition, do not give unnecessary details every kind of situation one by one herein.
Step 305, MSC sends local exchange to described BSS and sets up message, and this local exchange is set up message, and to be used to indicate described BSS be that the calling of satisfying the local exchange condition of obtaining of described step 304 is to setting up local exchange.
In the present embodiment, described local exchange is set up message and can be local exchange command (Local SwitchCommand) message, this this locality exchange command message is the SCCP message that connection is arranged, calling party that the calling of the satisfied local give-and-take conditions that described MSC can obtain by described step 304 is right and/or callee's SCCP connect, and send described local exchange command message to described BSS;
In the present embodiment, described local exchange order can be carried described right caller-marking (Call-ID) and/or the callee Call-ID of calling that satisfies the local exchange condition, for example: if the SCCP of described local exchange command messages by the right calling party of the described calling of satisfying the local exchange condition connects transmission, then described local exchange command messages can only carry the right callee Call-ID of calling that satisfies the local exchange condition, also can both carry described callee Call-ID, carry again described calling party Call-ID; If described local exchange command messages connects transmission by the right callee's of the described calling of satisfying the local exchange condition SCCP, then described local exchange command messages can only carry the right calling party Call-ID of calling that satisfies the local exchange condition, also can both carry described calling party Call-ID, carry again described callee Call-ID; If being connected SCCP by the described right calling party of calling who satisfies the local exchange condition with the callee, described local exchange command messages connects transmission, then connect the local exchange command messages that transmits by calling party SCCP and can only carry the right callee Call-ID of calling that satisfies the local exchange condition, the local exchange command messages that connects transmission by callee SCCP can only carry the right calling party Call-ID of calling that satisfies the local exchange condition, certainly, the described connection with callee SCCP by calling party SCCP is connected two local exchange command messages that transmit, and also can carry simultaneously right calling party Call-ID and the callee Call-ID of calling that satisfies the local exchange condition;
What deserves to be explained is, if in the described step 304, MSC is right from the calling that the calling centering of described BSS has been obtained a plurality of satisfied local give-and-take conditions, then in this step, described MSC can be respectively satisfies the right calling party of the calling of local give-and-take conditions and/or callee's SCCP connects by each, sends described local exchange command message to described BSS;
Preferably, if in described step 304, MSC is right from the calling that the calling centering of described BSS has been obtained a plurality of satisfied local give-and-take conditions, in order to save the signaling traffic of A interface, improve communication and carry out efficient, message is set up in described local exchange also can be this locality exchange indication (Local Switch Indication) message, this this locality exchange Indication message is connectionless SCCP message, described MSC can exchange the calling of the satisfied local give-and-take conditions that interpolation step 304 is obtained in the Indication message to tabulation to described this locality, and send the calling of carrying described satisfied local give-and-take conditions this locality exchange Indication message to described BSS to tabulation, wherein, described call list comprises every couple of right calling party Call-ID and callee Call-ID of calling that satisfies local exchange, in the use of reality, described call list can also comprise every pair of other right identification informations of calling that satisfy local exchange, every kind of situation is not given unnecessary details one by one herein;
In the use of reality, described MSC can send local exchange to BSS by the mode of above any one or combination and set up message, certainly, also can send local exchange to BSS and set up message, every kind of situation not given unnecessary details one by one herein by other modes.
Step 306, BSS receives the local exchange that described MSC returns and sets up message, sets up message according to described local exchange and sets up local exchange.
In the present embodiment, described BSS can set up message according to described local exchange by the mode of following any one or combination and set up local exchange:
Be local exchange Indication message if message is set up in described local exchange, and carry satisfy local give-and-take conditions calling to tabulation, the calling that then described BSS is described satisfied local give-and-take conditions to the calling of tabulation indication to setting up local exchange;
If it is the local exchange command messages that described local exchange is set up message, and this local exchange command messages connects transmission by the right calling party of the calling of satisfying the local exchange condition and/or callee's SCCP, then described BSS satisfies the calling of local exchange condition to setting up local exchange according to described local exchange command messages for described.For example, if described local exchange command messages connects transmission by the right calling party SCCP of the calling of satisfying the local exchange condition, then described BSS can according to the callee Call-ID that carries in the described local exchange command messages, be calling and the call setup local exchange corresponding to described calling party SCCP of described callee Call-ID indication; If described local exchange command messages connects transmission by the right callee SCCP of the calling of satisfying the local exchange condition, then described BSS can according to the calling party Call-ID that carries in the described local exchange command messages, be calling and the call setup local exchange corresponding to described callee SCCP of described calling party Call-ID indication; If being connected SCCP by the right calling party of the calling of satisfying the local exchange condition with the callee, described local exchange command messages connects transmission, then described BSS can be according to the described callee Call-ID that carries in the local exchange command messages of transmission that connects by calling party SCCP, calling and call setup local exchange corresponding to described calling party SCCP for described callee Call-ID indication, described BSS also can connect the calling party Call-ID that carries in the local exchange command messages of transmission by callee SCCP according to described, is calling and the call setup local exchange corresponding to described callee SCCP of described calling party Call-ID indication.What deserves to be explained is, if carried the calling of satisfied local give-and-take conditions right calling party Call-ID and callee Call-ID in the described local exchange command message simultaneously, then described BSS can be directly according to described calling party Call-ID and callee Call-ID, for the calling of described calling party Call-ID and callee Call-ID indication to setting up local exchange.
Certainly, in the use of reality, described BSS can also set up message according to described local exchange by other modes and set up local exchange, every kind of situation is not given unnecessary details one by one herein.
Step 307, BSS sends to described MSC and is used to indicate the message that local exchange is set up the result.
In the present embodiment, the described message that is used to indicate local exchange to set up the result can be for there being the SCCP message of connection, described BSS can connect by right calling party of the calling of described satisfied local give-and-take conditions and/or callee's SCCP to send and describedly is used to indicate local exchange to set up result's message, particularly, if the right this locality exchange of the calling of described satisfied local give-and-take conditions is set up successfully, the then described message that is used to indicate local exchange to set up the result is finished (Local Switch Complete) message for local exchange, the exchange of this this locality is finished message and can be carried local exchange and set up successful indication information, and right calling party Call-ID and/or the callee Call-ID of the calling of described satisfied local give-and-take conditions, if failure is set up in the right this locality exchange of the calling of described satisfied local give-and-take conditions, the then described message that is used to indicate local exchange to set up the result is local swap fault (Local Switch Failure) message, this this locality swap fault message can be carried local exchange and be set up the failure indication information, and right calling party Call-ID and/or the callee Call-ID of the calling of described satisfied local give-and-take conditions;
In the present embodiment, if BSS described in the step 306 is that a plurality of callings are to setting up local exchange, make flow in order to save to deliver a letter, the described message that is used to indicate local exchange to set up the result can also be connectionless SCCP message, for example: (Local Switch Performed) message is carried out in local exchange, message is carried out in this this locality exchange can carry the successful calling of local exchange foundation to tabulation, perhaps local exchange is set up the calling of failure to tabulation, perhaps satisfies this locality exchange of every pair of calling in the call list of local give-and-take conditions and this call list that satisfies local give-and-take conditions and sets up information such as result.
Step 308, MSC receives being used to that described BSS sends and indicates local exchange to set up result's message, is used to indicate local exchange to set up result's message according to described, to the calling of described satisfied local give-and-take conditions to operating.
Particularly, if describedly be used to indicate local exchange to set up result's message be that local exchange is finished message, then described MSC discharges the A interface user plane resource of calling to taking that described local exchange is finished the message indication; If describedly be used to indicate local exchange to set up result's message be the local exchange failed message, then to keep the right call state of the calling of described local exchange failed message indication constant for described MSC; If the described local exchange that is used to indicate is set up result's message for there not being the SCCP of connection message, carry out message such as local exchange, then described MSC carries out the information that message is carried according to described local exchange, satisfy the calling of local exchange condition to operating to described, for example: carry calling that local exchange is successfully established to tabulation if described local exchange is carried out message, then described MSC discharges calling the A interface user plane resource to take of calling to tabulating and indicating that described local exchange is successfully established, and, described MSC keeps calling that described local exchange is successfully established to beyond the tabulation, and the right call state of the calling of satisfying the local exchange condition that step 304 is obtained is constant.
