  • Mobile communication system, wireless controller, and extension transmitting/receiving server device selecting method
    Patent number: 8199691
    Abstract: An appropriate selection is controlled for selecting an extension transmitting/receiving server device for transmitting or receiving user data, to be transmitted or received between mobile station devices, to or from a radio base station device by employing extension transmission or reception of data, in a radio access network relaying data between a core network having a mobile switch station and the mobile station devices. While referring to a management table for managing statuses of extension transmitting/receiving server devices 30a to 30c, at least one of the extension transmitting/receiving server devices 30a to 30c is selected. The user data transmitted or received between mobile station devices through the selected extension transmitting/receiving server device is transmitted. This allows the control of an appropriate selection from the extension transmitting/receiving server devices.
