Communication method, communication apparatus and communication system
First Claim
1. A communication method enabling communication on a predetermined mobile communication network and communication on a predetermined wireless communication network different from the predetermined mobile communication network, comprising the steps of:
- switching, for predetermined packet communication, between the communication on the predetermined mobile communication network and the communication on the predetermined wireless communication network, and activating or deactivating a part concerning the predetermined wireless communication included in a mobile terminal, wherein the switching is made only for user data, and a control signal is transmitted always via the predetermined mobile communication network, and when a communication data amount, corresponding to a data volume transmitted/received by the mobile terminal, exceeds a predetermined threshold, the switching between the communication on the predetermined mobile communication network and the communication on the predetermined wireless communication network is carried out;
sending, via the mobile communication network, an instruction to activate a function of the mobile terminal concerning the communication on the wireless communication network;
the mobile terminal requesting via the predetermined wireless communication network for an address, and the address being then obtained by said mobile terminal via the predetermined wireless communication network in response thereto; and
confirming that the mobile terminal is in an environment such that communication on the predetermined wireless communication network is available when said address is included in a report from said mobile terminal.
