Abstract

A resource allocation request method in a wireless system, including base stations and terminals, includes the steps of: periodically broadcasting resource information, managed by the base stations, to the terminals; receiving and storing the periodically-broadcast resource information in the terminals; making a determination, in response to a resource allocation request, by comparing the parameter value of a resource, extracted from the stored resource information, with a preset critical value when a terminal receives an application command corresponding to the resource allocation request from a user; and, variably requesting resource allocation of the base stations according to the determinations by the terminals in response to the resource allocation requests.

Claims

1. A resource allocation request method in a wireless communications system including a plurality of base stations and a plurality of terminals, the method comprising the steps of:

periodically broadcasting resource information managed by the base stations to the terminals;

receiving and storing the periodically-broadcast resource information in the terminals;

determining, in response to a resource allocation request, whether the request can be processed, by comparing a parameter value of a resource, extracted from the stored resource information, with a preset critical value when a terminal of the plurality of terminals receives an application command, corresponding to the resource allocation request, from a user;

variably requesting resource allocation of the base stations according to the determination of the terminal in response to the resource allocation request; and

wherein when the resource allocation request cannot be processed, the terminal predetermines whether the resource allocation request can be processed, after a predetermined delay time, said predetermined delay time is longer than a transmission period of resource information broadcast by a base station of the plurality of base stations.

2. A resource allocation method as claimed in claim 1, wherein the resource information includes a present status of frequency use information, time slot information, and PN code information.

3. A resource allocation method as claimed in claim 1, wherein a base station of the plurality of base stations is one selected from the group consisting of a GSM base station, an IS-95 base station, an IMT2000 base station, and a wireless ATM base station.

4. A resource allocation method as claimed in claim 1, wherein the determination by the terminal of whether a resource allocation request can be processed is made by comparing a parameter value of the received resource information and a preset critical value.

5. A resource allocation method as claimed in claim 1, wherein the resource information broadcast by a base station of the plurality of base stations to the terminal includes a number of traffic channels pre-allocated by the base station, and a number of non-allocated channels among a total number of traffic channels.
