Method allowing ranging dependent on status of mobile station in broadband wireless access system

摘要

The present system relates to a broadband wireless access system, and more specifically to a method whereby resources for ranging are efficiently allocated to a mobile station with reference to the status of the mobile station, and also relates to a device for implementing the same. In one example of the present invention, the method for allowing a mobile station to range on a broadband wireless access system may comprise the steps of: selecting any one code from one or more codes contained in a ranging code subset corresponding to the status of a mobile station in one or more ranging codes subsets set in accordance with the purpose of the ranging by the mobile station mode; and transmitting the selected code to a base station.

1. A method for allowing a mobile station to perform a contention based ranging in a broadband wireless access system, the method comprising:
selecting a first ranging code subset or a second ranging code set that is different from the first ranging code subset among multiple ranging code subsets based on a purpose of the ranging and a mode of the mobile station, wherein the first ranging code subset is selected based on a first purpose of the ranging and a first mode of the mobile station, and the second ranging code subset is selected based on the first purpose of the ranging and a second mode of the mobile station; selecting any one code from one or more codes contained in the selected first or second ranging code subset; and transmitting the selected code to a base station, wherein said transmitting comprises: receiving uplink resource allocation information corresponding to the selected first or second ranging code subset including the transmitted code, from the base station; and transmitting a ranging request (AAI_RNG-REQ) message to the base station by using an uplink resource indicated by the uplink resource allocation information.
