Abstract
Upon detection of an environmental change in a neighborhood, a cellular phone makes selections of a communication device and a communication path, which are used for a communication. A communication packet transmitted from a communication corresponding terminal is distributed to the cellular phone that is the destination of the communication packet, and a PC physically positioned in the neighborhood of the cellular phone, according to the results of the selections, thereby switching from a communication using only the cellular phone to a communication using both the cellular phone and the PC.
Claims14
A method for switching a communication in a communication made by a communication system having a plurality of communication devices, the method comprising:
- detecting an environmental change in a communication device by one of the plurality of communication devices, wherein all of a change in a neighboring communication device physically located in a neighborhood of the communication device that detects the environmental change, a change in a state of a communication network to which the communication device that detects the environmental change is connected, and a change in a state of an application running in the communication device that detects the environmental change can be detected in detection of the environmental change;
- making a selection of a communication path for use in a communication and a selection of one or more communication devices for use in the communication from the plurality of communication devices, by using the communication device that detects the environmental change;
- and
- switching a communication using only a destination communication device to a communication using a plurality of communication devices by distributing a plurality of communication packets, all of which are transmitted from a communication corresponding terminal and in all of which the destination communication device is indicated as a destination, to the destination communication device and a neighboring communication device physically located in a neighborhood of the destination communication device based on results of the selections.
A communication system having a plurality of communication devices, comprising:
- a detector which detects an environmental change in a communication device, wherein the detector can detect all of a change in a neighboring communication device physically located in a neighborhood of the communication device, a change in a state of a communication network to which the communication device is connected, and a change in a state of an application running in the communication device in detection of the environmental change;
- a selector which makes a selection of a communication path for use in a communication and a selection of one or more communication devices for use in the communication from the plurality of communication devices, according to detection of the environmental change;
- and
- a switch which switches a communication using only a destination communication device to a communication using a plurality of communication devices by distributing a plurality of communication packets, all of which are transmitted from a communication corresponding terminal and in all of which the destination communication device is indicated as a destination, to the destination communication device, and a neighboring communication device physically located in a neighborhood of the destination communication device based on results of the selections.
A communication device in a communication system having a plurality of communication devices, comprising:
- a detector which detects an environmental change in a communication device, wherein the detector can detect all of a change in a neighboring communication device physically located in a neighborhood of the communication device, a change in a state of a communication network to which the communication device is connected, and a change in a state of an application running in the communication device in detection of the environmental change;
- a selector which makes a selection of a communication path for use in a communication and a selection of one or more communication devices for use in the communication from the plurality of communication devices, according to detection of the environmental change;
- and
- a switching instructor which causes a communication using only a destination communication device to be switched to a communication using a plurality of communication devices by issuing an instruction to distribute a plurality of communication packets, all of which are transmitted from a communication corresponding terminal and in all of which the destination communication device is indicated as a destination, to the destination communication device, and a neighboring communication device physically located in a neighborhood of the destination communication device based on results of the selections.
