[0035] Please refer to Fig. 1, the flow process of the first embodiment of the method of the present invention includes:

[0036] 101. Send information including special operation codes;

[0037] Wherein, during the call waiting process, the base station controller (BSC, Base Station Controller) sends a FWI (Flash with Information) message containing a special operation code to the mobile switching center (MSC, Mobile Switching Center) according to the operation of the user.

[0038] 102. Process according to the special operation code.

[0039] Wherein, after receiving the FWI message sent by the BSC, the MSC performs corresponding processing according to the special operation code included in the FWI.

[0040] Call waiting process among the present invention comprises:

[0041] 1. Call waiting notification state, that is, the first user is talking with the second user, and the third user calls the first user, then MSC will notify the first user of a new incoming call;

Abstract

A call controlling method and a communication system are disclosed in the present invention, used for promoting the flexibility of the call control. The method comprises: during call waiting course, a user control base station sends information containing special operation code to a mobile switching center; the mobile switching center processes the call according to the received special operation code. The communication system comprises: a user terminal, a base station controller and a mobile switching center; the user terminal is used for sending information containing special operation code according to a selecting control base station controller of the user; the base station controller is used for sending information containing special operation code to the mobile switching center; the mobile switching center is used for receiving information containing special operation code sent by the base station controller, and according to the special operation code processing the call. The present invention can effectively promote the flexibility of the call control.

Description

technical field [0001] The invention relates to the communication field, in particular to a call control method and a communication system. Background technique [0002] Call Waiting (CW, Call Waiting) is a supplementary service in the mobile communication system. It is provided to the user during a call. If another user calls the user again, the user can choose to accept the second call, and can call between two parties. Switch between calls. [0003] In the call waiting service of the CDMA system, it is assumed that a mobile subscriber (MS, Mobile Subscriber)_A has call waiting capability and is talking with MS_B. MS_C calls MS_A at this time, and when MS_A is on call waiting, MS_A can choose to answer the call of MS_C. [0004] If MS_A connects to the call of MS_C, MS_B enters the call hold state, and MS_B hears the call hold tone played by MSC, for example, "Please don't hang up, the number you dialed is in communication". At this time, MS_A and MS_C talk to each othe...
