Problems solved by technology

[0005] 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

[0045] A call connection method. This embodiment is applicable to a scenario where the calling user initiates a call connection to the base station system in the first call connection after the air interface between the calling user and the base station system is dropped. The flowchart is as follows figure 2 Shown, including:

[0046] Step 101: After the air interface connection between the calling user and the base station system is interrupted, the calling user sends a call again request message to the base station system; the call again request message includes the information of the called user;

[0047] Step 102: The base station controller in the base station system receives the call again request message within a specified time, and determines that the called user corresponding to the call again request message is the same as the previous call request message sent by the calling user. Whether the corresponding called users are the same, if they are the same, go to step 103; ...

Embodiment 2

[0060] A call connection method. This embodiment is suitable for a specified time after the air interface connection between the calling user and the original base station system (that is, the serving base station system of the network where the calling user initiates a call for the first time) is interrupted, The calling user moves across base stations, and the calling user initiates a call request again 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, the call connection method is as flow chart image 3 Shown, including:

[0061] Step 201: After the air interface connection between the calling user and the original base station system is interrupted, the call request message is sent to the current base station system;

[0062] Step 202: The base station system where the current station is located ...

Embodiment 3

[0071] A call connection method. This embodiment is suitable for the first call connection between the calling user and the original base station system, and the calling user's serving base station system is switched to the current base station system, where the original base station system and 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. If the calling user initiates a call request to the current base station system within the specified time, the call connection method is as follows: Figure Figure 4 Shown, including:

[0072] Step 301: After the calling user and the called user make the first call connection, the calling user switches from the base station system where they are originally to the base station system where they are currently located, and the mobile switching center sends a handover request message to the base station where i...

Abstract

The embodiment of the invention discloses a call connecting method and call connecting equipment which are applied to the field of communication technology. The call connecting method is suitable for the condition that after the gap connection between a base station system and a calling user is interoperated and re-original call request information transmitted by the calling user is received, if a called user which corresponds to the re-original call request information is the same with the called user which corresponds to an original call request transmitted by the calling user last time, the gap connection between the base station system and the calling user is controlled to be reestablished. Compared with a method for removing the previous call connection by a mobile switching center and establishing recalling in the prior art, the call connecting method can prevent the condition of call collision; and the process of establishing the gap connection is not sensed by the called user,thereby having favorable user experience.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a call connection method and device. Background technique [0002] 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. It is easy to cause the air interface connection between the user equipment and the base station system to be interrupted. It will cause the air interface of the user equipment that is on the call to drop. The 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 system is the air interface connection, and the connection between the base station controller and the mobile switching center in the base station system is the A port connection. [0003] In the prior art, when the air interface of the cal...
