Embodiment Construction

[0018] The present invention will be described in detail below by taking the CDMA2000 HRPD communication system as an example.

[0019] As shown in Figure 1, the CDMA2000 HRPD system includes AT (Access Terminal, Access Terminal), AN (Access Network, Access Network), Access Network Authentication Authorization and Accounting (AN AAA, Access Network Authentication Authorization and Accounting), group Control function (PCF, PacketControl Function) and packet data service node (PDSN, Packet Data Service Node). A9, A11, and A12 are signaling links, and A8 and A10 are data links.

[0020] Fig. 2 is the forward channel structure of HRPD, wherein the pilot frequency channel, the media access control channel and the traffic channel are the same as the protocol, for the control channel, the present invention further divides the control channel into the dedicated control channels of a plurality of clusters, the cluster's The dedicated control channel is distinguished by CCShortPacketsM...

Abstract

This invention discloses one HRPD group set communication system send signal method of CDMA modulation, which comprises the following steps: in the HRPD front signal channel, dividing the signal channel into multiple set special control signal channels by use of CCShortPacketsMACIndex property; in establishing of set group base station divides each set to align one special control channel with each set belonging to self terminal control signal channel and with relative front terminal simultaneous pack.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for sending signaling in a CDMA HRPD (High Rate Packet Data, High Rate Packet Data) mobile cluster 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. The cellular trunking communication system combines the cellular communication system with the dedicated dispatching communication system, which not only expands the business scope of the cellular communication system, but also frees the trunking communication system from the functional and regional limitations of the dedicated...
