Communication control apparatus, communication apparatus and communication system
View Patent ↗An EV-DO terminal module is made up of hardware and software for implementing the function as an EV-DO terminal. A W-LAN terminal module is made up of hardware and software for implementing the function as an AP of W-LAN. An information exchange terminal module has a function equal to that of the W-LAN terminal module. A control module has a dialup function and a function based on PPP protocol and is a hardware and software module for controlling the EV-DO terminal module, the information exchange terminal module, and the W-LAN terminal module.
1. A master communication apparatus comprising:
an information generation section that generates information concerning base stations to which the master communication apparatus can connect;
a connection section that directly connects with at least one slave communication apparatus;
an information exchange section that exchanges, via the connection section, information concerning base stations to which the slave communication apparatus can connect;
a determination section that determines a base station to which the slave communication apparatus should connect based on the information concerning the base stations to which the slave communication apparatus can connect, acquired by the information exchange section from the slave communication apparatus;
an instruction section that instructs the slave communication apparatus to connect to the base station determined by the determination section, via the connection section; and
a relay section that relays between a user terminal and the base stations.
2. A slave communication apparatus comprising:
an information generation section that generates information concerning base stations to which the slave communication apparatus can connect;
a connection section that directly connects with at least one another slave communication apparatus or a master communication apparatus;
an information exchange section that transmits directly or via the another slave communication apparatus, the information generated by the information generation section to the master communication apparatus, and receives, directly or via the another slave communication apparatus, an instruction of handoff to a base station to which the slave communication apparatus should connect, transmitted from the master communication apparatus;
a handoff section that performs the handoff to the base station to which the slave communication apparatus should connect, based on the instruction of the handoff received by the information exchange section via the connection section; and
a relay section that relays between a user terminal and the base stations.
3. The master communication apparatus according to claim 1 ,
wherein the information generated by the information generation section involves information concerning a communication speed predicted in a case that the master communication apparatus connects to the base stations to which the master communication apparatus can connect.
4. The slave communication apparatus according to claim 2 ,
wherein the information generated by the information generation section involves information concerning a communication speed predicted in a case that the slave communication apparatus connects to the base stations to which the slave communication apparatus can connect.
5. The master communication apparatus according to claim 4 ,
wherein if the communication speed with the base station to which the slave communication apparatus should connect is smaller than a first threshold value, the handoff section determines that another base station with a predicted communication speed equal to or greater than a second threshold value is the base station to which the slave communication apparatus should connect.
6. The slave communication apparatus according to claim 4 ,
wherein if the communication speed with the base station to which the communication apparatus should connect is smaller than a first threshold value, the determination section determines that another base station with a predicted communication speed equal to or greater than a second threshold value is the base station to which the slave communication apparatus should connect.
