Description

  The present invention relates to a communication terminal device capable of measuring and bidirectionally communicating its own position information such as GPS (Global Positioning System) and capable of communicating with a large number of communication terminal devices via the Internet.

  In recent years, modes of communication by communication terminal devices such as mobile phones have been diversified, and in addition to conventional voice calls by circuit switching, new modes of communication such as packet communication using the Internet are performed. For example, there is “chat mail” in which conversation is performed by exchanging characters between communication terminal devices in real time (see Patent Document 1). Chat mail is one of communication modes called “group communication” in which a group is formed between members registered in advance and data such as characters is communicated in real time within the group.

  In addition, as one of group communications attracting attention recently, there is one called PTT (Push To Talk) or PoC (Push to Talk Over Cellular). In PTT, a plurality of communication terminal devices forming a group perform a real-time voice call by VoIP (Voice over Internet Protocol). One-to-many voice communication can be performed by simultaneously transmitting common voice data from one communication terminal device on the transmission side to a plurality of communication terminal devices on the reception side.

  On the other hand, recent mobile phones are equipped with a function (hereinafter referred to as a GPS function) that acquires information on its geographical position using GPS (Global Positioning System) and displays it on a map. Has appeared. If you use this GPS function, you can know exactly where you are now with a map, so you can reach places you have never been without getting lost.

Therefore, by using both the “group communication” and the “GPS function” described above, it becomes possible to share location information in real time between those performing group communication. Therefore, those having communication terminal devices having both the “group communication” and the “GPS function” can be used for waiting or the like by combining both functions.
