Problems solved by technology

[0005] When the called user does not answer the phone for a long time and the call is forwarded, or the called user is not paged for many times and the call is forwarded, it will take a certain amount of time (for example, the called user does not answer the call for 20 seconds. , the duration of not being able to page the called user is at least 10 seconds), and if the user to whom the first call is forwarded also undergoes call forwarding (that is, the second call forwarding), it will result in the call of the calling user terminal The processing timer expires, which leads to the call being torn down, that is, when the call initiated by the calling user is forwarded by two or more calls, the call processing timer of the calling user terminal will time out, resulting in the call being torn down. It is difficult for the calling user to make a call, which ultimately leads to a decrease in user satisfaction

Embodiment Construction

[0020] refer to figure 1 , which is a flow chart of a preferred embodiment of the method for performing call control during call setup in the present invention.

[0021] This embodiment is an application scenario of an intra-office call. The call initiated by the calling user is forwarded twice without answer, wherein the calling user initiates a call setup, and sends a call setup message to the mobile switching center / mobile switching center server ( SETUP) (step S101); Mobile switching center / mobile switching center server sends routing request message (Send RoutingInformation, SRI) to home location register (different from the back, is called SRI (1)) (step S102); Home location register Return the roaming number and call forwarding data (step S103) of the called user by routing request message response (different from the following, called SRI ACK (1); after being connected to the called user, if the called user does not answer Phone, call forwarding (step S104) occurs for...

Abstract

The invention discloses a call control method, which judges whether the call initiated by the calling user is forwarded by the second call; when the judgment result is yes, instructs the calling user terminal to stop the call processing timer. A corresponding mobile communication switching device is disclosed. In the present invention, when the call initiated by the calling user is forwarded by two or more calls, by stopping the call processing timer of the calling user terminal, the call processing timer of the calling user terminal can be prevented from overtime, and further Calls are prevented from being dropped, and the calling user can finally make a call, thereby improving user satisfaction.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, the present invention relates to a mobile communication switching device and a call control method. Background technique [0002] Mobile switching center / mobile switching center server is a circuit domain call processing device, which completes all functions of circuit type calls, such as: controlling call connection, managing communication services of mobile stations in this network or with other networks, etc., and providing billing information . [0003] At present, the call forwarding service can be implemented in the mobile switching center / mobile switching center server. The so-called call forwarding service means that when the called user is inconvenient to answer the call for some reason, the call can be forwarded to another mobile user or landline users so that the user does not miss the call. Currently available call forwarding services in...
