Embodiment 1

[0037] Embodiment 1, a switching method. The first terminal establishes a call with the second terminal through the first base station, and the call link established between the first terminal and the second terminal is a first service link.

[0038] After the first service link is established, if the switching device on the first service link supports general switching logic, it sends its own office route information to the first terminal through an office route notification message. The office route notification message can be an in-band message or an out-of-band message. The switching device on the first service link can also send its own office direction information to the second terminal through the office direction notification message, the storage of the office direction information by the second terminal, and the way the second terminal initiates a handover are the same as those of the first terminal Similarly, in this embodiment, only the first terminal is used as an...

Embodiment 2

[0063] Embodiment 2, a switching device, used for switching when a first service link has been established between a first terminal and a second terminal.

[0064] FIG. 2 is a schematic structural diagram of a switching device according to Embodiment 2 of the present invention.

[0065] The receiving unit 201 is configured to receive a call request from the first terminal, where the call request carries office direction information of the switching device on the first service link, and the called party indicated by the call request is the second terminal;

[0066] The link unit 202 is configured to send a link establishment request to the switching device on the first service link according to the call request received by the receiving unit, where the link establishment request carries address information of the first terminal and the second terminal.

[0067] The call request carries office direction information of multiple switching devices on the first service link; further...

Embodiment 3

[0074] Embodiment 3, a switching device, used for switching when a first service link has been established between a first terminal and a second terminal.

[0075] FIG. 3 is a schematic structural diagram of a switching device according to Embodiment 3 of the present invention.

[0076] The receiving unit 301 is configured to receive a link establishment request from the first switching device, where the link establishment request carries address information of the first terminal and the second terminal;

[0077] A link unit 302, configured to establish a link between the switching device and the first switching device according to the link establishment request received by the receiving unit;

[0078] A checking unit 303, configured to check the connection relationship table according to the address information of the first terminal and the second terminal in the link establishment request received by the receiving unit;

[0079] The switching unit 304 is configured to, when...

Abstract

The embodiment of the invention discloses a switch method. A first service link is established between a first terminal and a second terminal by switching equipment. The method comprises the following steps that: the first switching equipment receives a call request of the first terminal; the first switching equipment sends a link establish request to the switching equipment on the first service link according to the call request. The embodiment of the invention also provides a switch method, switching equipment and a terminal unit. By adopting the switch method, the switching equipment and the terminal unit, all one needs to do is to update the switching equipment on the first service link to support the universal switch logic and second switching equipment is not required to support the universal switch logic. The invention solves the problem that all switches are difficult to update one by one to support the universal switch logic. The switching mode provided by the embodiment of the invention has easy manipulation and general compatibility.

Description

technical field [0001] The present invention relates to the communication field, in particular to a switching method, switching equipment and terminal equipment. Background technique [0002] In the wireless cellular mobile network, the mobile station (MS) can roam arbitrarily. During the call process of the user, due to the movement of the MS, the coverage area of ​​the original first base station (BS) is exceeded, and it enters other second BS. Coverage, at this time, it is necessary to make the mobile station connect and communicate with the second BS through the handover process, so as to keep the user's call uninterrupted. [0003] At present, the wireless cellular mobile network provides two switching technologies: hard switching and soft switching. [0004] Hard handoff: When the MS is moving, it will report to the mobile switching center (MSC) after detecting that the signal of the first BS has deteriorated to a certain threshold or that the signal of the second BS ...
