Problems solved by technology

Although this patented technology can effectively reduce adjacent channel interference, and the call quality is better when the system load is low, because its allocation is still based on the cell, it cannot realize the load sharing of TRX channel resources, which will also lead to high-load TRX. Aging; and the patented technology also cannot identify the impact on operating indicators due to changes in TRX device characteristics

Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] figure 1 It is a flowchart of a channel allocation method in the prior art, and is an allocation method for organizing channel resources in units of BTSs. The organization of channel resources takes the cell as the unit, and the BSC completes the allocation of wireless channels in the cell to which the mobile station is attached according to the channel allocation request of the mobile station. figure 1 The content has been described in detail above.

[0040] The present invention mainly focuses on different TRXs in the same BTS: according to different characteristic indexes of TRXs, TRXs in a BTS can be divided into several priority levels, and the priority level of each TRX can be automatically adjusted regularly during system operation.

[0041] figure 2 It is the general flowchart of the channel allocation method proposed by the...

Abstract

The invention includes following steps: (1) initializing overall system; (2) initializing is carried out on BSC before a adjustment cycle; (3) within a adjustment cycle, selecting, allocating, and releasing channel, as well as TRX queue in same priority are adjusted; (4) after completing a adjustment cycle, recalculating and adjusting priority of each TRX, then executing step (2). Comparing with prior art, the invented method for allocating channels reduces influence on network planning caused by interferece of adjacent frequency in high limit. The invention optimizes process for allocating channel, and gives preference to resources of channel with good quality. Thus, in a certain degree, index for running overall system is raised.

Description

technical field [0001] The present invention relates to a GSM (Global System for Mobile communication, global system for mobile communication) mobile communication system, and in particular, relates to a channel allocation method on a BSC (Base Station Controller, base station controller). technical background [0002] In the GSM system, the BSS system (Base Station Sub-System, base station subsystem) is responsible for the management of radio resources and the radio transceiver function. The BSS includes a BSC and a BTS (Base Transceiver Station, base station). The BSC is the intelligent center of the BSS system, and its main function is to manage wireless resources. Channel allocation is done on the BSC. [0003] Channel allocation is a very important part of the GSM system, and the quality of the channel allocation method directly affects the performance of the GSM system. In the GSM specification 08.08, according to the interference situation of the wireless channel, ...
