Abstract: User equipment includes a first communication entity that supports a transport layer protocol and a network layer protocol, and that transmits data a transmission source address of which is set to be a certain network layer address, to a network; and a second communication entity that supports the transport layer protocol and the network layer protocol, and that by commonly using the certain network layer address, is able to transmit the data the transmission source address of which is set to be the certain network layer address, to the network, wherein the second communication entity includes a storage device that stores a port number not being overlapping a port number which is used in the first communication entity, and a control device that performs determining processing which, when the received data does not include the port number, determines that the destination of the received data is the first communication entity.

Abstract: A radio network controller disposed on a network, for implementing effective use of bands in use considering the characteristics of the use form of the users, not by physical expansion, the radio network controller having a user resource management section for managing information for characterizing a user connected to the radio network controller, a plurality of user signal data conversion sections for performing conversion processing of the user signal data respectively, and a resource control section for performing resource control for securing bands for the plurality of user signal data conversion sections, wherein the resource control section secures a band appropriate for the characteristics of the user by controlling the shift of calls among the plurality of user signal data conversion sections.

Abstract: A multimedia signal processing apparatus comprises communication service units having a plurality of types of signal processing modes corresponding to a plurality of types of communication service classifications, a communication service classification identifying unit for identifying, on the basis of signal processing request information on one call communicated from a higher-rank node, a communication service classification for that call, and a mode control unit for controlling a signal processing mode of the communication service unit to a mode suitable for the communication service classification identified in the communication service classification identifying unit.
