Definitions
- the present invention relates to a mobile communication terminal and a mobile communication system having the mobile communication terminal, and more particularly to a technique for selecting a network in a mobile communication terminal that supports communication with a plurality of networks.
- Non-Access-Stratum functions related to Mobile Station (MS) in idle mode "[3GPP TS23.122 V7.5.0 (2006-06)]. That is, all radio access technologies [UMTS (Universal Mobile Telecommunications System) GSM (Global System for Mobile communications) etc.] supported by the mobile communication terminal are searched. All the detected networks are notified to the user, and the user selects the desired network.
- UMTS Universal Mobile Telecommunications System
- GSM Global System for Mobile communications
- the name of the detected network operator (network operator A, B, C, D, etc.) and its wireless connection technology (RAT: Radio Access Technology) [GSM, UMTS, etc.] is displayed.
- RAT Radio Access Technology
- the technology for detecting and connecting any of a plurality of networks by a mobile communication terminal is described in, for example, Japanese Patent Application Laid-Open No. 2002-2 7186 and Japanese Patent Application Laid-Open No. 2005-236 769. Has been.
- the problem with service types is that the available service types (voice calls, videophone calls, international calls, browsers, streaming, etc.) available for each network are displayed on the network selection screen of the related technology mobile communication terminal. Do not display. For this reason, it is impossible to know whether the desired service is available or not unless the user selects a network and actually tries it.
- the available service types voice calls, videophone calls, international calls, browsers, streaming, etc.
- the problem of the service area is that information on the serviceable area of each network is not displayed on the network selection screen of the mobile communication terminal of the related technology. For this reason, even if the user selects a network, the service area may be removed by a small movement and the user may be out of service area.
- the problem of electric field information is that the received electric field information (stability of wireless communication) of each network is not displayed on the network selection screen of the mobile communication terminal of the related technology. For this reason, even if a user selects a network, the wireless quality may be poor and the service may not be used smoothly, or it may be out of service.
