Problems solved by technology

[0005] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: the hash values ​​calculated by different terminals according to the CDMA channel list message broadcast by the base station may be the same, resulting in multiple terminals with equal probability Compete to use the same CDMA channel, so different access services cannot be provided for terminals with different priorities

Embodiment Construction

[0023] The technical solutions of the embodiments of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] figure 1 It is a flowchart of a method for a terminal to select a camped CDMA channel provided by the first embodiment of the present invention. This embodiment describes a method for a terminal to select a camped CDMA channel from the perspective of a base station.

[0025] In this embodiment, the CDMA channels configured on the base station are divided into at least two CDMA channel groups, and each CDMA channel group is used to provide services for terminals with different priorities. That is, different priority terminals correspond to different CDMA channel groups.

[0026] 11: The base station determines all CDMA channels configured with paging channels or broadcast control channels in each CDMA channel group.

[0027] For the CDMA IS-95 system, the base station needs to broadcast the...

Abstract

The invention provides a method and a device for terminals to select resident CDMA channels. CDMA channels configured on a base station is divided into at least two CDMA channel groups, wherein each CDMA channel group is used for supplying service for terminals with different priority levels, and the base station is used for determining that all the CDMA channels of a paging channel or a broadcast control channel are configured in each CDMA channel group. The method for terminals to select resident CDMA channels comprises the following step of: broadcasting a channel list message in the coverage area of the base station by the base station through all the CDMA channels of the paging channel or the broadcast control channel configured in each CDMA channel group, wherein the channel list message comprises channel marks of all the CDMA channels in each CDMA channel group, which are configured with the paging channel or the broadcast control channel, so that the terminals with different priority levels can select the resident CDMA channels in the CDMA channel groups.

Description

technical field [0001] The embodiment of the present invention relates to the field of wireless communication technologies, and in particular to a method and device for a terminal to select a CDMA channel to camp on. Background technique [0002] In a Code-Division Multiple Access (CDMA) cellular system, the CDMA channel can be divided into a traffic channel and a control channel according to the different information functions transmitted by the CDMA channel. For the CDMA IS-95 system, the control channels configured by the base station include the pilot channel, the paging channel (forward) and the access channel (reverse); for the CDMA2000 1X system, the control channels include the pilot channel, the paging channel ( Forward), Access Channel (Reverse), Broadcast Control Channel (Forward), Common Control Channel (Forward), Enhanced Access Channel (Reverse) and Quick Paging Channel (Forward). [0003] According to the CDMA system version supported by the base station, the...
