Embodiment Construction

[0023] Hereinafter, the present invention will be further described in detail through specific embodiments in conjunction with the accompanying drawings.

[0024] Fig. 1 is a schematic diagram of an access parameter message of the HRPD communication system according to the present invention. Compared with the access parameter message specified in the HRPD protocol, a field "AccessChannelCount (access channel number)" is added. The length of this field can be determined according to the number of ATs in the cell or the number of physical resources of the base station. If there are more access channels established, the number of bits in the field length should be larger. This field specifies the number of access channels under the cell. If the value of this field is N, it means that there are N access channels under the cell, and the number of these access channels is 0~N-1.

Abstract

This invention discloses one method to realize multiple interface signal channel on HRPD communication system, which comprises the following steps: a, establishing signal channels in the system; b, the system is connected with parameters through area composed of area interface signal channel parameters and number; c, AT receives parameters information to compute one interface channel by Harsh formula to get signal long code mask and to connect long signal channel by HRFD agreement and to add one interface section; d, sending reverse signals in channel to compute one signal channel to send reverse signals by step c.

Description

Technical field: [0001] The present invention relates to the technical field of mobile communication, in particular to a method for implementing multiple access channels in an HRPD (High Rate Packet Data) communication system. Background technique: [0002] The access channel is a channel used for AT (Access Terminal) to send reverse signaling to AN (Access Network). The HRPD protocol stipulates that each cell has only one access channel. [0003] The access channel is identified by the long code mask. The long code mask structure of the access channel specified by the HRPD protocol is shown in Table 1. [0004] Bit 41 40 [39:32] [31:0] MIACMAC 1 1 AccessCycleNumber Permuted(ColorCode|SectorID[23:0]) [0005] Table 1 Access channel long code mask [0006] The long code mask of the access channel (MIACMAC, Long Code Mask of I of Access Channel, access channel I long code mask) consists of AccessCycleNumber (access cy...
