1. A radio resource allocating method for a bandwidth request transmission in a base station (BS) of a wireless communication system, the method comprising:

  • allocating a first radio resource for the bandwidth request transmission of a mobile station (MS), the radio resource allocated to the MS while providing a service;

    receiving a bandwidth request message from the MS via the allocated first radio resource, the bandwidth request message including a first field that includes first information indicating a type of the service for which the MS is communicating with the BS and a second field that includes second information, wherein a type of the second information is determined based on the first information, wherein the second information is an identifier of the MS when the first information indicates that the service is a delay-sensitive service and wherein the second information is a size of requested bandwidth when the first information indicates that the service is a delay-tolerable service; and

    allocating a second radio resource to the MS in response to the bandwidth request message, wherein a size of the second radio resource is pre-determined by negotiation between the BS and the MS when the first information indicates that the service is the delay-sensitive service and wherein the size of the second radio resource is determined according to the size of the requested bandwidth when the first information indicates that the service is the delay-tolerable service.
