Abstract: A communication device implementing a function of retransmitting to a destination includes an operation unit detecting an input operation, a communication module starting a transmission to a destination specified by the input operation, a storage unit storing one or more pieces of destination specifying information on every destination, a judging module judging whether the communication can be attained upon the transmission, a searching module searching for, if judged to be impossible of the communication, one or more pieces of destination specifying information stored corresponding to the destination from the storage unit, a display unit displaying a list of the searched destination specifying information, a selection module accepting a selection of a desired piece of destination specifying information from the list of the destination specifying information displayed, and a retransmitting module retransmitting based on the selected destination specifying information.

Abstract: In a mobile radio network control method and device which can meet a call establishment request of a high-speed user data communication service as much as possible, when a connection call requests a high-speed user data communication service, a maximum resource required for performing a high-speed user data conversion in response to the request is secured, when an occurrence of a channel switchover from a high-speed user data communication state to a low-speed user data communication state is detected during communication, a maximum resource required for performing a low-speed user data conversion in response to the detection is secured and a call reestablishment is performed, and the resource secured for performing the high-speed user data conversion is released.

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.

Abstract: A data transfer device for a portable telephone which device is capable of achieving efficient and reliable transfer of data and minimizing the influence on vocal communication and restrictions on the availability of added services. When data is to be transferred from data terminal equipment connected to a portable telephone to another data terminal equipment connected to a portable telephone at a remote side of a network during vocal communication, transfer data quantity measuring unit measures the data quantity of the transfer data. Channel selecting unit compares the measured data quantity with a predetermined value, and selects one of a fast associated control channel and a slow associated control channel in accordance with the result of comparison. Using the channel selected by the channel selecting unit, data transfer unit sends the transfer data input from the data terminal equipment to a radio link.
