METHOD AND DEVICE FOR ACCESS TO BASE STATION PERFORMED IN MOBILE STATION IN COMMUNICATIONS SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a multiple access system which introduces less delays and makes more efficient use of available system resources.

SOLUTION: In the base station accessing method, a mobile station accesses a base station by arbitrarily selecting a first reverse-link common control channel from a set of random access channels. The mobile station transmits a request portion of an access probe over the first reverse-link common control channel. The request portion is subject to collision with other signals. The request portion comprises a hash identification which is derived from a uniquely identifying number by using hash function. The hash identification uniquely identifies the mobile station. The mobile station receives a channel assignment message from the base station, designating the hash identification and a reserved access channel. The reserved access channel provides communication with a low probability of contentions. The mobile station transmits a message portion of the access probe over the reserved access channel.
