Mobile communication system and gateway selecting method thereof
First Claim
1. A mobile communication system for providing a service of connecting a mobile terminal to a predetermined communication network, comprising:
- a plurality of gateways, each including;
a data obtaining section for obtaining data stored in a predetermined information server connected to the communication network in response to a request from the mobile terminal;
a format converting section for converting the format of the obtained data according to restrictions on resources of the mobile terminal;
a load measuring section for measuring load imposed on predetermined processes including the data obtainment and the format conversion; and
a load data communicating section for communicating load data indicating information relating to the measured load, and a mobile communication control apparatus including;
a load data obtaining device for obtaining the load data communicated from each gateway;
a load data storage device for storing the obtained load data; and
a gateway selecting device for selecting one of the gateways, which is connected to the mobile terminal, based on the obtained load data when the mobile communication control apparatus receives a request for obtaining the data stored in the information server from the mobile terminal.

Abstract
The load of each gateway for connecting the mobile network and a predetermined communication network is distributed. In each gateway, data stored in a predetermined information server connected to the communication network is obtained in response to a request from the mobile terminal; the format of the obtained data is converted according to restrictions on resources of the mobile terminal; load imposed on predetermined processes including the data obtainment and the format conversion is measured; and load data indicating information relating to the measured load is sent. In a mobile communication control apparatus for selecting one of the gateways, the load data communicated from each gateway is stored, and when receiving a request for obtaining the data stored in the information server from the mobile terminal, the apparatus selects a gateway based on the load data.
