Stochastic signature sequence allocation method in enhanced FACH base on multiple frequency points

增强型fach中的基于多频点的随机签名序列分配方法

Abstract

The invention discloses a random signature sequence allocation method based on multi-frequency-point in an enhanced FACH, which realizes flexible allocation to enhanced FACH (E-FACH) access so as to achieve the purposes of distinguishing access level and service QoS, transferring service information of users and the like. The technical proposal is as follows: the method comprises the steps: a terminal sends signature sequences of PRACH message access and E-RUCCH message access at a master frequency point of a cell, and sends a signature sequence of the enhanced FACH access at an auxiliary frequency point of the cell so as to lead a network to judge whether the access is the enhanced FACH access according to the information of the frequency points of the received signature sequences; and the information of the frequency points is broadcasted in a system message of a service cell, the network responses to signature on the master frequency point of the cell or a frequency point required by the system by virtue of the FPACH towards the access initiated by the terminal, and the information of the frequency point of the FPACH is broadcasted in the system message. The method is applied to the field of mobile communication.
本发明公开了增强型FACH中的基于多频点的随机签名序列分配方法,实现对增强型FACH(E-FACH)接入的灵活配置,达到区分接入等级、区分业务QoS以及传递用户业务量信息等目的。其技术方案为:方法包括:终端在小区主频点上发送PRACH消息接入和E-RUCCH消息接入的签名序列给网络,在小区辅频点上发送增强型FACH接入的签名序列,以使网络可以根据接收到的签名序列的频点信息来判断接入是否为增强型FACH接入;在服务小区的系统消息中广播频点信息,网络对于终端发起的接入,在小区主频点或者系统规定的频点上通过FPACH对签名进行响应,FPACH的频点信息在系统消息中广播。本发明应用于移动通信领域。
