Abstract
A base station (1) is connectable to a mobile station (4) by a plurality of Radio Access Technologies (RATs) including first and second RATs. The base station (1) is configured to be able to use a communication path (400) that passes through a first upstream network (140) corresponding to the first RAT, when the mobile station (4) performs communication via the second RAT. This enables, for example, efficient use of the upstream networks when the Multi-RAT base station (1) supports a plurality of upstream networks.
Claims18
A radio communication system comprising:
- a base station connectable to a mobile station using a plurality of radio access technologies including first and second radio access technologies;
- and
- an upstream network corresponding to the first radio access technology,
- wherein the base station is configured to, when the mobile station communicate with the base station using the second radio access technology, use a communication path that passes through the upstream network without passing through another upstream network.
A base station connectable to a mobile station using a plurality of radio access technologies including first and second radio access technologies and also connectable to an upstream network corresponding to the first radio access technology, the base station comprising:
- a communication path control unit configured to use, when the mobile station communicate with the base station using the second radio access technology, a communication path that passes through the upstream network without passing through another upstream network.
A communication method for a base station connectable to a mobile station using a plurality of radio access technologies including first and second radio access technologies and also connectable to an upstream network corresponding to the first radio access technology, the communication method comprising:
- using, when the mobile station communicate with the base station using the second radio access technology, a communication path that passes through the upstream network without passing through another network.
A mobile station used in a radio communication system,
- the radio communication system comprising:
- an upstream network corresponding to a first radio access technology;
- and
- a base station that is configured to be connectable to the mobile station using a plurality of radio access technologies including the first radio access technology and a second radio access technology, and is configured to, when the mobile station communicate with the base station using the second radio access technology, use a communication path that passes through the upstream network without passing through another upstream network, and
- the mobile station is configured to be connected to the base station using at least one of the first and second radio access technologies.
A non-transitory computer-readable medium storing a program for causing a computer to execute a communication method for a base station, wherein the base station is connectable to a mobile station using a plurality of radio access technologies including first and second radio access technologies and also connectable to an upstream network corresponding to the first radio access technology, and
- the method comprises controlling the base station so as to, when the mobile station communicate with the base station using the second radio access technology, use a communication path that passes through the upstream network without passing through another upstream network.
