The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A communication method in a communication system, wherein the communication system comprises:
a mobile terminal;
a communication server that distributes data to the mobile terminal; and
a plurality of base stations that are capable of relaying the data, and one of the base stations among the plurality of base stations is responsible for relaying the data, and
the communication method comprises:
transmitting, to the communication server, restriction instruction information to restrict a data transmission rate, by a first base station that is responsible for relaying the data among the plurality of base stations; and
hand-overing, by the first base station, causing a second base station different from the first base station to take over the responsibility of relaying.
2. The communication method according to claim 1, further comprising transmitting, by the second base station, after the second base station performs the hand-overing, release instruction information to release the restriction of the data transmission rate to the communication server.
3. The communication method according to claim 1, wherein the transmitting includes omitting transmitting the restriction instruction information according to a type of service to which the data to be relayed belongs.
4. The communication method according to claim. 2, wherein the transmitting includes transmitting the release instruction information after the second base station takes over the responsibility of relaying and further after a predetermined period elapses.
5. The communication method according to claim 1, wherein
each of the plurality of base stations comprises a buffer to store the data to be relayed, and
the communication method further comprises transmitting the restriction instruction information to further restrict the data transmission rate to the communication server, by the second base station, if an amount of the data stored in the buffer exceeds a predetermined criterion.
6. A base station in a communication system which includes a mobile terminal and a communication server that distributes data to the mobile terminal, the base station being responsible for relaying the data, wherein
the base station comprises:
a relay control section that, after transmitting restriction instruction information to restrict a data transmission rate to the communication server, causes another base station different from the base station to take over the responsibility of relaying.
7. The base station according to claim 6, wherein if the relay control section takes over the responsibility of relaying from another base station different from the base station, transmits release instruction information to release the restriction of the data transmission rate to the communication server.
8. The base station according to claim 6, wherein the relay control section omits transmission of the restriction instruction information according to a type of service to which the data to be relayed belongs.
