Embodiment 1

[0028] Embodiment 1, the first service link has been established between the first transceiver of the MS and the opposite end, including the following steps:

[0029] Each transceiver of the MS performs frequency signal search and measurement;

[0030] Based on the MS search and measurement results, it is judged whether it is necessary to initiate a handover to the second base station;

[0031] If it is necessary to initiate a handover, the second transceiver of the MS initiates a new call to the second BS, and the new call carries the address information of the opposite end;

[0032] establishing a second service link between the MS and the second BS through the second transceiver of the MS;

[0033] The MS switches the first service link to the second service link.

[0034] Wherein, the opposite end is a terminal establishing a service link with the MS, which may be a mobile station or a fixed user equipment. The service established between the MS and the opposite end may...

Embodiment 2

[0037] Embodiment two, see figure 1 and figure 2 , the first service link has been established between the MS and the opposite end, including the following steps:

[0038] 1. The MS judges that it needs to initiate a handover to the second BS;

[0039] 2. The MS sends an initial call connection request to the second BS, carries the address information of the opposite end, and requests the network to which the second BS belongs to build a second service link between the MS and the opposite end;

[0040] 3. After the second service link is set up, the switching device judges that the new call is handover, and switches the service link between the MS and the opposite end to the second service link. The switching device is the first service link and the second service link. A switching device through which service links pass together.

[0041] The switching device judges that the new call is actually a handover, so it does not perform the operation of establishing a new call, ...

Embodiment 3

[0065] Embodiment three, see image 3 , taking the MS equipped with the first transceiver and the second transceiver as an example, the modes of the first transceiver and the second transceiver are both CDMA, and the MS equipped with other modes and equipped with more than two transceivers The situation can be obtained based on the principle of this embodiment. Taking the MS and the opposite end talking as an example, the handover mode of establishing other types of services between the MS and the opposite end can also be obtained based on the principle of this embodiment. The method for implementing switching in this embodiment includes the following steps:

[0066] 301. The MS determines to initiate a hard handover to the second BS according to the signal measurement result, and sends an initial call connection request message to the second BS.

[0067] 302. The second BS receives the initial call connection request message, and establishes a service link between the second...

Abstract

This invention discloses a switching method, a MS and an exchanging device. The method comprises the following steps: each transceiver of the mobile station processes the searching and measuring of frequency signal; the mobile station judges whether there is need to initiate the switching to a second base station based on the result of searching and measuring; initiating a new call to the second base station through a second transceiver of the mobile station; the new call takes the address information of the opposite end; building a second business link between the mobile station and the second base station through the second transceiver of the mobile station; the mobile station switches the first business link to the second business link. Adopting MS to judge there is need to initiate the switching and executing the switching process through adopting MS to initiate the new call, which effectively avoids the trouble of developing interoperability interface and proposal for supporting the cross-net switching need among each wireless network.

Description

technical field [0001] The invention relates to the field of mobile station switching, in particular to a switching method, a mobile station (MS) and switching equipment. Background technique [0002] In the wireless cellular mobile network, the MS can roam arbitrarily. During the user call, due to the movement of the MS, the MS moves beyond the coverage area of ​​the first base station (BS) originally accessed and enters the coverage area of ​​other second BSs. Sometimes 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 conversation 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 ...
