Embodiment Construction

[0015] The method of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] The specific allocation content of the air resource allocation involved in the present invention includes the forward / reverse basic channel unit, the channel unit of the forward supplementary channel, the Walsh code (WalshCode), and the frame offset. Among them, the forward / reverse basic channel unit is used for basic channel modulation and demodulation in the air, and the channel unit of the forward supplementary channel is used for modulation and demodulation of the forward supplementary channel in the air. The channel units are all located in the modem chip; Walsh code is CDMA2000 technology Forward channel modulation parameters; frame offset parameters used in CDMA2000 air channel.

Abstract

The invention discloses a method of allocating base-station resources of CDMA2000-mode cluster communication system in mobile communication field, in cluster calling, allocating independent forward-backward basic service channel to each member of the cluster, where the forward compensatory channel adopts a mode of sharing resources to save aerial power resources and increase aerial interface capacity, overcoming the defect that existing technique can not combine CDMA2000 system with cluster system, effectively reducing the forward emission power occupied by the cluster calling, and reducing the mutual interference between users, improving calling effect, and increasing the capacity of the whole system by increasing aerial capacity.

Description

technical field [0001] The invention relates to the third generation mobile communication system and trunking communication system, in particular to an air resource allocation method of the CDMA2000 standard trunking communication system. Background technique [0002] The trunking communication system refers to a dedicated mobile communication system in which multiple users share a group of wireless channels and dynamically use these channels. It is a command and dispatch system. It is widely used in enterprises, institutions, industrial and mining, oil fields, farms, public security, police and military departments with high command and dispatch functions. [0003] The main feature of the CDMA2000 trunking communication system is that it adopts a half-duplex communication mode, which can realize fast connection, and supports group calls (that is, one-to-many call mode). In the trunking communication system of CDMA2000 standard, the users in the group are required to share ...
