Abstract
A home agent receives a communication packet sent out from a source terminal to a mobile terminal as a destination to transfer the communication packet to the mobile terminal connected to a foreign network. This home agent requests the mobile terminal, based on a measured result of internal resources, to bypass the home agent to perform a communication with a source terminal.
Claims19
A home agent for receiving a communication packet sent out from a source terminal to a mobile terminal as a destination to transfer the communication packet to the mobile terminal connected to a foreign network,
- wherein the home agent requests the mobile terminal, based on a measured result of internal resources, to bypass the home agent to perform a communication with the source terminal.
A home agent for receiving a communication packet sent out from a source terminal to a mobile terminal as a destination to transfer the communication packet to the mobile terminal connected to a foreign network,
- wherein the home agent requests the mobile terminal, based on a route cost of a network, to bypass the home agent to perform a communication with the source terminal.
A home agent for receiving a communication packet sent out from a source terminal to a mobile terminal as a destination to transfer the communication packet to the mobile terminal connected to a foreign network,
- wherein the home agent requests the mobile terminal, based on at least any one of a measured result of internal resources and a route cost of a network, to bypass the home agent to perform a communication with the source terminal.
A mobile communication system, comprising:
- a home agent which receives a communication packet sent out from a source terminal to a mobile terminal as a destination to transfer the communication packet to the mobile terminal connected to a foreign network;
- and
- a mobile terminal which performs a communication with the source terminal,
- wherein the home agent requests the mobile terminal, based on a measured result of internal resources, to bypass the home agent to perform a communication with the source terminal, and
- the mobile terminal bypasses the home agent to perform the communication with the source terminal when the mobile terminal receives the request from the home agent.
A mobile communication system, comprising:
- a home agent which receives a communication packet sent out from a source terminal to a mobile terminal as a destination to transfer the communication packet to the mobile terminal connected to a foreign network;
- and
- a mobile terminal which performs a communication with the source terminal,
- wherein the home agent requests the mobile terminal, based on at least any one of a measured result of internal resources and a route cost of a network, to bypass the home agent to perform a communication with the source terminal, and
- the mobile terminal bypasses the home agent to perform the communication with the source terminal when the mobile terminal receives the request from the home agent.
A mobile communication system, comprising:
- a home agent which receives a communication packet sent out from a source terminal to a mobile terminal as a destination to transfer the communication packet to the mobile terminal connected to a foreign network;
- a mobile terminal which performs a communication with the source terminal;
- a memory which stores route management information;
- and
- a route cost calculating section which calculates a route cost based on the route management information,
- wherein the home agent requests the mobile terminal, based on a route cost of a network acquired by the route cost calculating section, to bypass the home agent to perform a communication with the source terminal, and
- a mobile terminal which bypasses the home agent to perform the communication with the source terminal when the mobile terminal receives the request from the home agent.
