Communication controller and communication controlling method for controlling a movable communication terminal device

Abstract

A communication controller and a communication controlling method are provided, even when functionalities of the communication controller included in a communication system such as UTRAN or the like, so that the services of the functionalities are available broadly in the whole system. An RNCfor controlling a movable communication terminal device, in cooperation with the communication controller, receives a request for provision of a service. The RNCincludes: a signal transmitter/receiverfor discriminating the type of the requested service; an HSUPA communication request discriminating section; a call controller; a transfer destination search tablefor storing information that associates a service that can be requested by the service request receiving means and another RNC that can provide the service; and a transfer destination searching sectionfor identifying another RNC that can provide the service, based upon the information stored in the transfer destination search table, if there is a request for HSUPA communication that cannot be provided by the RNC. The RNCtransfers the request for the provision of the service to another RNC identified by the transfer destination searching section
