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. With this configuration, in the multimedia signal processing apparatus, the signal processing mode of the communication service unit is controlled to a mode suitable for the service classification for each call, which can considerably decrease the number of communication service units to be mounted and significantly reduce the probability of the rejection of newly arrived call.

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.
