Apparatus and method for controlling resources in a core network
First Claim
1. A base station apparatus having a serving cell coupled to a network, the base station apparatus comprising:
- a processor coupled to a memory and configured to;
determine a hold period for which a core network resource of the core network is to be held for a mobile station apparatus coupled to the base station apparatus, in accordance with a communication frequency of the mobile station apparatus, the core network being configured to couple a radio access network and a public network, the communication frequency of the mobile station apparatus comprising an average communication interval of the mobile station apparatus, the core network resource being used for setting a bearer in the core network for the mobile station apparatus;
modify the hold period based on at least one of;
an available capacity of resources of the base station apparatus, a number of users coupled to the base station apparatus in the serving cell and a radio signal quality of the mobile station apparatus; and
cause a gateway apparatus in the core network to release the core network resource after the hold period, by transmitting information indicating the hold period to the gateway apparatus.

Abstract
A base station apparatus determines, in accordance with at least one of a communication frequency of a mobile station apparatus, a congestion state of a core network that connects a radio access network and a public network, a number of users being located in a cell of the base station apparatus, and a radio state, a hold period for which a core network resource is to be held, where the core network resource is used for setting a bearer in the core network for the mobile station apparatus. The base station apparatus transmits information indicating the determined hold period to a gateway apparatus in the core network, thereby causing the gateway apparatus to release the core network resource after a period corresponding to the hold period has elapsed.
