Embodiment Construction

[0032] Such as figure 2 As shown, the mobile station starts handover from the first mobile switching center (Mobile Services Switching Center, MSC) to the second MSC, and when it is in the handover steady state, starts the handover steady state timer. When the handover is completed, the mobile station sends a disconnection request message to the second MSC to the first MSC.

[0033] If for some reason, the disconnection message is lost and the first MSC cannot receive the disconnection request message, so the second MSC cannot receive the disconnection response message (or the disconnection response message is lost) from the first MSC. The second MSC releases related resources on the second MSC after waiting for the disconnection response message to expire.

[0034] After the first MSC finds that it is in the handover steady state for a certain period of time (the handover steady state timer expires), it sends a resource check request message to the second MSC and starts the...

Abstract

A method and system for releasing handover resources are disclosed, the method includes the following steps: the first mobile switching device initiates the resources checking to the second switching device, releasing the correlate resources on the first mobile switching device if the first switching device determines the checking is failed. The releasing method and system disclosed in the present invention enables the normal releasing of the correlate resources on the mobile switching device by the checking of the resources inter-offices when the handover is performed inter-offices, and the resources utility rate is also improved.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a method and system for releasing resources of a mobile switching center. Background technique [0002] Mobile users may switch between offices due to location changes during data services, such as figure 1 As shown, its specific handover and disconnection process is as follows: when the first mobile switching center (MobileServices Switching Center, MSC) finds that the mobile station needs to be handed over to the second MSC during the data service process for the mobile station, it initiates a call to the second MSC. Handover request message (FACDIR2). After receiving the handover request message, the second MSC allocates wireless channels and terrestrial circuits for the mobile station, and returns a handover response message (facdir2) to the first MSC after the allocation is successful. After the handover is successful, the second MSC sends a handover comp...
