Abstract:
1. A method for providing load state information of a Base Station (BS) in a wireless communication system, the method comprising: determining a ratio of a whole allocated resource compared to a whole resource of the BS and a ratio of a resource allocated for traffic flow requiring a fixed or minimum rate compared to the whole resource; generating at least one load indicator for indicating a first value expressing the ratio of the whole allocated resource and a second value expressing the ratio of the resource allocated for the traffic flow requiring the fixed or minimum rate; and transmitting the at least one load indicator to a Mobile Station (MS), wherein the MS determines a resource amount necessary for activating a traffic flow for at least one BS, determines whether there is a BS comprising a spare resource which is more than the necessary resource amount using the first values of BSs, if there is the BS comprising the spare resource which is more than the necessary resource amount selects the BS comprising the spare resource which is more than the necessary resource amount as a BS to access, and, if there is not the BS comprising the spare resource which is more than the necessary resource amount, selects a BS comprising a ratio of a resource allocated for the traffic flow requiring the fixed or minimum rate as the BS to access.
