Embodiment
Embodiment of the present invention provides a kind of method that realizes local exchange, this method can be finished following operation by BSC or BTS, the described this locality of the specific embodiment of the invention is exchanged for, in packet switching (PS Packet Switched) territory business, mutual communication between the mobile subscriber, all in same BSC or BTS scope, BSC or BTS are by certain algorithm for the both sides of communication, the mutual data of control communicating pair are finished local exchange not by core net by BSC or BTS.
This method comprises the steps: as shown in Figure 3
Step 31, receipt of call are set up request message;
This call setup request message can be sent by calling subscriber's (also being terminal).
After carry out step 31, can also carry out following operation, receive the Indication message that starts local exchange;
This Indication message that starts local exchange can be sent by mobile switching centre (MSC Mobile Switching Center).
Whether step 32, detection calling subscriber and called subscriber satisfy the condition of local exchange; Carry out following step as satisfying, do not satisfy then end operation;
This step can be finished by base station equipment, the concrete mode of its realization can for, base station equipment detects calling subscriber and called subscriber whether in the scope of same base station equipment, situation in the scope of same base station equipment, detect calling subscriber and called subscriber and satisfy the condition of local exchange, otherwise be the condition of discontented unabridged version ground exchange.Described base station equipment can be BSC or BTS.
Step 33, carry out call setup;
Step 34, set up the network work table, be used to store calling subscriber and called subscriber's identifying information;
This identifying information is in that (High level Data Link Control HDLC) under the situation of transmission method, preferentially selects carrier frequency identification information (TRX Index) and user totem information (User Identity, User ID) based on High-Level Data Link Control;
(Internet Protocol IP) under the situation of transmission method, preferentially selects IP address and User Datagram Protoco (UDP) (User Datagram Protocol, UDP) port numbers in agreement Network Based;
Under situation based on asynchronous transfer mode (ATM Asynchronous Transmission Mode) transmission method, preferential tunnel sign (the Virtual Path Identifier/Virtual Channel Identifier that selects, VPI/VCI) and gap marker (ChannelIdentifier, CID).
Above-mentioned identifying information only is the preferential identifying information of selecting, the mode that the described identifying information of the specific embodiment of the invention does not limit to above-mentioned identifying information.
Step 35, after receiving voice flow, according to the network work table customer identification information of described voice flow is replaced.
This step can be finished by BSC or BTS, is the preferred implementation that the example explanation realizes this step below with BSC,
Situation A, BSC receive after the voice flow, and under the situation of voice flow for calling subscriber's transmission, BSC finds out called subscriber's identifying information according to the network work table, and the customer identification information of this voice flow is replaced to called subscriber's identifying information as described;
Situation B, BSC receive after the voice flow, and under the situation of voice flow for called subscriber's transmission, BSC inquires calling subscriber's identifying information according to the network work table, and customer identification information is replaced to calling subscriber's identifying information as described.
Above-mentioned steps 31～35 all can be finished by BSC or BTS.
For better describing the described method of the specific embodiment of the invention, now with concrete application scenarios the specific embodiment of the present invention is described in conjunction with the accompanying drawings:
The embodiment 1 described method that realizes that this locality exchanges is the example explanation with BSC, as shown in Figure 4, transmission means is the HDLC transmission means in the concrete enforcement of the present invention, this customer identification information is TRX Index and User ID, carrying customer identification information on the HDLC frame can realize by following method, increases TRX Index and User ID on the HDLC frame head; This method comprises following operation:
Step 41, BSC receive the call request message of setting up of calling subscriber's transmission,
Step 42, BSC receive the local Indication message that exchanges of startup that MSC sends after MSC transmits this call setup request message;
Step 43, BSC detect calling subscriber and called subscriber whether in same BSC area territory, are then to carry out following step, otherwise end operation;
Step 44, BSC carry out call setup;
Step 45, BSC set up the network work table, and this network work table is used to store calling subscriber and called subscriber's TRX Index and User ID;
Step 46, BSC are after receiving voice flow, and TRX Index and the User ID with described voice flow replaces according to this network work table.
The method that realizes this step illustrates in above-mentioned situation A and situation B, is not just giving unnecessary details here.
Said method is as being based on ATM or IP transmission means, only needing identifying information with calling subscriber and called subscriber be modified as gets final product customer identification information that should transmission means, said method also can be finished by BTS, and when finishing said method by BTS, except reducing the volume of transmitted data between BSC and the core net, can also reduce the volume of transmitted data between BTS and the BSC, thereby better realize the purpose of conserve network resources.
