Radio access communications network, dynamic load distribution apparatus and dynamic load distribution method used in the same
First Claim
1. A radio access communications network comprising a plurality of base stations and a resource allocation calculation apparatus which performs allocation calculation for the purpose of controlling resources including at least frequency with respect to the plurality of base stations, wherein:
- the resource allocation calculation apparatus includes fixed allocation resource calculation means for calculating fixed allocation resources for the purpose of securing connections in the entire area managed by the plurality of base stations, and dynamic allocation resource calculation means for calculating dynamic allocation resources which are allocated to the plurality of base stations for the purpose of distributing load; and
the resources are allocated with frequencies which each of the fixed allocation resource calculation means and dynamic allocation resource calculation means handles.

Abstract
A dynamic load distribution apparatus in which resource allocation calculation for distributing load can be implemented by a simple and dynamically flexible algorism. An input apparatus receives from the network administrator the information on location of each base station apparatus or the information on base station apparatus. A load detection apparatus detects the traffic or the number of terminals with respect to each base station apparatus. Fixed allocation resource calculation unit of a resource allocation calculation apparatus 3 performs resource allocation calculations. Dynamic allocation resource calculation unit receives the information on traffic or the number of terminals detected by the load detection apparatus to perform the resource allocation suitable for load distribution. A resource allocation control apparatus sets resources into each base station apparatus based on the information on resource allocation.
