Method for selecting network system in mobile terminal and storsage medium storing program of same
First Claim
1. A method for a mobile terminal being operable in network systems of a plurality of communication types each being different from each other to select a network system to be employed when said mobile terminal having a list of other network systems to one of which said mobile terminal desires to be connected in a radio channel receives a request for searching other network systems being usable from said network system being now connected due to lowering in signal reception levels provided by said network system being now connected, said method comprising:
- a step of measuring signal reception levels provided by said other network systems and deciding a network system that is connectable to said mobile terminal based on said measured signal reception levels and on data about network systems that are desired to be connected, providing a report about decisions made by said mobile terminal to said network system being now connected; and
a step of switching said network system being now connected to a new designated network system in response to a request for switching said network system being now connected.

Abstract
A method for a mobile terminal to select a network system which enables the mobile terminal to be connected through a radio channel to the network system desired by a user at a time the mobile terminal has to switch the network system being connected due to lowering in signal reception levels.
The method includes searching of other network systems by the mobile terminal having a list of other network systems and measuring signal reception levels provided by the other network systems, deciding of a new network system that can be used by the mobile terminal based on the signal reception levels and data on network systems desired by the user, providing reports about the decision to the network system being connected and switching the network system from the network system being now connected to the new network system designated by the network system in response to a request for switching.

10. A storage medium storing program to cause to a computer to execute a method by which a mobile terminal being operable in network systems of a plurality of communication types each being different from each other, selects a network system, said method comprising:
-
a step of preparing a list containing other network systems to which said mobile terminal desires to be connected, a step of measuring signal reception level of other network systems when said mobile terminal receives said request for searching other network systems being usable from a network system being now connected due to lowering in signal reception levels in said mobile terminal and of deciding a usable network system based on said signal reception levels of other network systems and on data about network systems to which said mobile terminal desires to be connected and of reporting to said network system being now connected and a step of switching to designated other network system in response to a request for switching said network system fed from said network system being now connected.
