Radio resource allocation method and base station using the same
First Claim
1. A resource allocation method for a base station to allocate a new radio resource to a link between the base station and a requesting mobile station in a cell site of the base station, comprising the steps of:
- causing the base station to detect use-state information of radio resources in the cell site of the base station of concern and in respective cell sites of neighboring base stations and priority information of mobile stations using the same radio resource of both the base station of concern and the neighboring base stations by accessing an external radio resource management table;
causing the base station to determine whether an up/down link direction related to a non-allocated radio resource in the cell site of the base station of concern is the same as an up-down link direction related to an allocated radio resource in one of the cell sites of the neighboring base stations;
causing the base station to allocate a new radio resource to the link between the base station of concern and the requesting mobile station based on both the use-state information and the priority information in said detecting step and based on a result of the determination in said determining step;
causing the base station to determine whether a level of priority of the requesting mobile station is higher than a level of priority of each of the mobile stations using the radio resources allocated in the cell sites of the neighboring base stations, based on the priority information related to the base station of concern and the priority information related to the neighboring base stations; and
causing the base station to determine whether allocation of the non-allocated radio resource in the cell site of the base station of concern to the link is possible.

Abstract
In a radio resource allocation method of the present invention, use-state information of radio resources and priority information of mobile stations using the same radio resources of both a base station of concern and neighboring base stations is detected at the base station of concern. A new radio resource is allocated to a link between the base station of concern and a requesting mobile station in a cell site of the base station of concern based on the use-state information and the priority information of both the base station and the neighboring base stations.

9. A base station including a resource allocation control unit which allocates a new radio resource to a link between the base station and a requesting mobile station in a cell site of the base station, the resource allocation control unit comprising:
-
a first unit detecting use-state information of radio resources in the cell site of the base station of concern and in respective cell sites of neighboring base stations and priority information of mobile stations using the same radio resources of both the base station of concern and the neighboring base stations by accessing an external radio resource management table; a second unit allocating a new radio resource to the link between the base station of concern and the requesting mobile station based on the use-state information and the priority information; a determining unit determining whether a an up/down link direction related to a non-allocated radio resource in the cell site of the base station of concern is the same as an up/down link direction related to an allocated radio resource in one of the cell sites of the neighboring base stations, wherein said second unit allocates the new radio resource to the link based on both the use-state information and the priority information detected by the first unit and based on a result of the determination provided by the determining unit; a third unit determining whether a level of priority of the requesting mobile station is higher than a level of priority of each of the mobile stations using the radio resources allocated in the cell sites of the neighboring base stations, based on the priority information related to the base station of concern and the priority information related to the neighboring base stations; and a fourth unit determining whether allocation of the non-allocated radio resource in the cell site of the base station of concern to the link is possible. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
