Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system for making a call or presenting information to a portable telephone terminal / PHS terminal located within a certain range by designating a time zone or the like. And its method.

[0002]

2. Description of the Related Art Mobile phones, PHSs, etc. are widely used. In addition, services and the like for notifying the position of the mobile terminal based on information such as which base station the mobile terminal of the mobile phone / PHS is in the call area have been put into practical use. Further, for example, Japanese Patent Laid-Open No. 10-326241,
JP-A-8-256142 and JP-A-10-3223.
Japanese Unexamined Patent Application Publication No. 97 and Japanese Unexamined Patent Application Publication No. 9-91358 disclose a method of selecting a terminal as a communication partner based on the attributes of each terminal stored in a database. Further, Japanese Patent Laid-Open No. 10-234071 discloses a method of measuring the signal strength / phase between three base stations and a mobile terminal to specify the position of the mobile terminal.

However, it is not always possible to specify a specific position and select a communication partner simply by associating the call area with the position of the mobile terminal. For example, when the train stations B and C are included in the call area A, if "mobile terminal in call area A" is designated and a communication partner is selected, the selected mobile terminals include B station and C station. The mobile terminals near both stations are selected as communication partners, and only the mobile terminals near station B cannot be selected as communication partners.

On the contrary, when the D station is included in both the call areas E and F, if a terminal near the D station is selected as a communication partner, the mobile terminal communicating with the base station for the call area E is selected. Can only be selected as the communication partner, but D
A mobile terminal that is near the station and is communicating with the base station for the communication area F cannot be selected as the communication partner. Even if an attempt is made to add a communication area in which a mobile station exists to a database and select a mobile terminal as a communication partner, such a problem cannot be solved.

Further, based on the detected position of the mobile terminal, the communication partner is selected by designating the positional range and time zone of the communication partner, or the attributes (hobbies, age, etc.) of the communication partner are further designated. In the past, it was not possible to choose.
