Abstract

In order to transmit data via a plurality of types of communication networks in accordance with the communication environment at the time of data transmission, a mobile telephone, which is capable of being connected to a plurality of types of mobile communication networks, is provided with a detector for detecting the communication status of a mobile communication network based on a control signal transmitted from this mobile communication network; a storage unit for storing the detected communication status; an allocation unit for allocating data to each connected mobile communication network based on the amount of the data addressed to another communication apparatus and the stored communication status; and a transmitter for transmitting the data that has been allocated to each mobile communication network to the respective mobile communication networks.

Claims

1. A mobile communication terminal capable of being connected to a plurality of types of communication networks, comprising:

detection means for detecting a communication status of the communication network on the basis of a control signal transmitted from the communication network;

storage means for storing the communication status detected by the detection means;

allocation means for allocating data to each connected communication network based on the amount of the data addressed to another communication apparatus and the communication status stored by the storage means; and

transmission means for transmitting the data allocated to each communication network by the allocation means to the respective communication networks.

2. The mobile communication terminal according to claim 1, wherein the allocation means re-allocates the data addressed to the other communication apparatus when the communication status of the communication network is updated by the storage means.

3. The mobile communication terminal according to claim 1, wherein the allocation means allocates the data addressed to the other communication apparatus to the respective communication networks based on the communication speed of the respective communication networks.

5. A communication apparatus capable of being connected to a plurality of types of communication networks and carrying out data communication with the mobile communication terminal described according to claim 1, comprising:

reception means for receiving data, which has been allocated and transmitted to each communication network by the mobile communication terminal, from the respective communication networks; and

reconfiguration means for carrying out reconfiguring so as to restore pre-allocation data from the data received by the reception means.

6. A data reception method for a communication apparatus, which is connected to a plurality of types of communication networks, and receives data from the mobile communication terminal described according to claim 1, comprising the steps of:

a receiving step receiving data, which has been allocated and transmitted to each communication network by the mobile communication terminal, from the respective communication networks; and

a reconfiguring step reconfiguring so as to restore pre-allocation data from the data received in the receiving step.

4. A data transmission method for a mobile communication terminal capable of being connected to a plurality of types of communication networks, comprising the steps of:

a detecting step detecting a communication status of the communication network on the basis of a control signal transmitted from the communication network;

a storing step storing the communication status detected in the detecting step;

an allocating step allocating data to each connected communication network based on the amount of the data addressed to another communication apparatus and the communication status stored in the storing step; and

a transmitting step transmitting the data allocated to each communication network in the allocating step to the respective communication networks.
