When receiving an extension connection request from a first mobile terminal, a first route selection device selects a first extension connection route from among a plurality of extension connection routes and transmits the type of the first extension connection route and calling-side address information used on the first extension connection route to a second route selection device. The second route selection device selects a second extension connection route from among the plurality of extension connection routes and transmits the type of the second extension connection route and called-side address information used on the second extension connection route to the first route selection device. If the second extension connection route coincides with the first extension connection route, an extension connection is established between the first mobile terminal and the second mobile terminal via the first extension connection route.

Extension connection method and route selection device

A mobile station that includes a mobile station controller which performs a process of responding to a call signal and a wireless base station that includes a base station controller which performs a determination of a priority of the call signal to be transmitted to the mobile station and a baseband unit that transmits a first call signal having a first priority to the mobile station and that stores a second call signal having a second priority in a queue and performs a transmission process wherein when the second call signal has been discarded, the baseband unit notifies the mobile station of information representing that the second call signal has been discarded and the mobile station controller executes, when deciding the second call signal has been discarded, a processing of an inquiry response to the wireless base station.

Wireless communication system, wireless base station, mobile station, and wireless communication method

A base station includes at least one first application section, a determining section, and a controlling section. Each of the first application sections executes one of a plurality of first application programs corresponding to one of a plurality of first application services utilizing a first wireless communication service provided by a mobile virtual network operator. The determining section receives a connection request to connect to the first application service from a first terminal for using the first wireless communication service, and determines the first application section corresponding to the first application service specified in the connection request. The controlling section controls communications between the determined first application section and a server managed by the mobile virtual network operator and between the determined first application section and the first terminal.

Base station, wireless communication system, and wireless communication method

A wireless communication system, includes: a first base station; a second base station; a first terminal which transmits call connection data to the first base station; a second terminal which receives a call connection request; and a management device which manages location and movement of the first terminal, wherein the first base station employs a handover procedure to notify the management device, when receiving the call connection data from the first terminal, that a call connection destination of the second terminal which has received the call connection request is changed, and notifies the first terminal about a frequency of the second base station, and the first terminal transmits call connection data to the second base station based on the notified frequency.
