Embodiment Construction

[0025] Generally, when the number of channels in a cell is saturated or close to saturation, it indicates that the activeness of users in the current cell is relatively high, and the number of users applying for access or cut-in at the same time is also large. At this time, for the system equipment, how to select the appropriate user among the applied users is important to improve the efficiency of channel usage. This is because in the case of the same resource, selecting a user that occupies less resources (lower load factor) can accommodate more users and improve channel usage efficiency. Accordingly, the present invention adopts a stricter admission control method when the cell load reaches a preset value, so as to access users with less load demand as much as possible.

[0026] The admission control method of the present invention performs pre-analysis according to the current load status, that is, adjusts the sequence of access judgment based on the QoS of the UE call ser...

Abstract

This invention is an admission control method of wireless communication system, it belongs to admission and control of new caller in CDMA system. New callerí»s call request is decided whether to admit according to the analysis of corresponding testing parameters after the request is received by the system equipment. A valve value of district load is pre-set for the call of asking for receiving of new user before the analysis. Queue pool is set to order the calls according to there priorities. Pre admission and analysis is done when the district loads get to the valve value and the calls are sent into queue pool according to situation. The less load need user are accepted by using more strict admission control type when the district loads get to the value set before. More users can be accepted in the same resources, and the service efficiency can be raised.

Description

Technical field: [0001] The invention belongs to a kind of admission control for new calling user or handover user in code division multiple access (CDMA) system when performing wireless resource allocation and management. Background technique: [0002] Communication systems, especially wireless communication systems, include a plurality of communication channels via which users of such systems communicate with each other and with the system. Wireless communication systems such as CDMA systems and others have a certain capacity; ie they are limited by the number of these communication channels. Usually, the capacity is directly related to the number of users of the system, and the CDMA system is a typical interference-limited system. If the air interface load of the cell is infinitely increased, the coverage area of ​​the cell will be lower than the planned value, and the service quality of existing connections cannot be guaranteed. Before accepting a new connection, admis...
