Problems solved by technology

[0006] When the mobile switching center disconnects the previous call, it is prone to call collision. For example, when calling again to process the called data, the previous call has not completed the disconnection operation for the same called party. At this time, the status of the called user Is not free, will cause another call to be rejected because the called user is busy

Embodiment 1

[0037] A call connection method. This embodiment is applicable to the scene where the calling user initiates a call connection to the base station system in the initial call connection after the call is dropped on the air interface between the calling user and the base station system. The flow chart is as follows figure 2 shown, including:

[0038] Step 101, when the air interface connection between the calling user and the base station system is interrupted, the calling user sends a re-initiation request message to the base station system; the re-initiation request message includes the information of the called user;

[0039] Step 102, the base station controller in the base station system receives the call initiation request message again within the specified time, and judges that the called user corresponding to the call initiation request message again is different from the call initiation request message sent by the calling user last time. Whether the corresponding calle...

Embodiment 2

[0052] A call connection method, this embodiment is applicable to after the air interface connection between the calling user and the original base station system (that is, when the calling user initiates a call for the first time, the serving base station system of the network) is interrupted, within a specified time, When the calling user moves across base stations, the calling user initiates a new call origination request to the serving base station system of the current network (hereinafter referred to as the current base station system), where the original base station system and the current base station system are in the same mobile exchange Center, at this time the call connection method is shown in the flow chart image 3 shown, including:

[0053] Step 201, after the air interface connection between the calling user and the original base station system is interrupted, send a call initiation request message to the current base station system;

[0054] Step 202, the cu...

Embodiment 3

[0063] A call connection method, this embodiment is applicable to the first call connection between the calling user and the original base station system, the serving base station system of the calling user is switched to the current base station system, wherein the original base station system and the original base station system The current base station system is in the same mobile switching center, and then the air interface connection between the calling user and the current base station system is interrupted, and the calling user initiates a call request to the current base station system within the specified time, the call connection method is as follows: picture Figure 4 shown, including:

[0064] Step 301, after the calling user and the called user make the first call connection, the calling user switches from the original base station system to the current base station system, and the mobile switching center will send a handover request message to the current base st...

Abstract

The embodiment of the invention discloses a call connection method and equipment, which are applied in the technical field of communication. The call connection method provided by the embodiment of the invention is suitable for cross-base station movement of a user after null connection between a base station system and a calling user is interrupted. When the calling user initiates a recall, a mobile switching center requires establishing the call connection on a current base station system and removing previous call connection on the original base station system if a connection management service request message sent by the current base station system is received and a called user which corresponds to the connection management service request message is the same as a called user which corresponds to a connection management service request message sent by an original base station of the calling user; a base station system in which call connection is established is different from a base station system from which call connection is removed, so that the situation of call collision can be avoided; and moreover, a null connection establishing process in the embodiment of the invention is not sensed by the called user, so that user experience is good.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of August 5, 2009, an application number of 200910161907.5, and an invention title of "Call Connection Method and Equipment". technical field [0002] The invention relates to the technical field of communication, in particular to a call connection method and equipment. Background technique [0003] In the field of communication technology, the base station covers the user area through wireless communication. The signal coverage quality is affected and restricted by various factors such as terrain and buildings, which may easily cause the air interface connection between the user equipment and the base station system to be interrupted. It will cause air-interface call drop on the user equipment that is in the call. A base station system includes a base station and a base station controller. The connection between the base station and the user in the base station syst...
