摘要： A mobile telephone unit which combines operation of a respective portable mobile telephone and a communication unit. The mobile telephone unit includes at least one portable telephone, a communication unit and a buffer unit. The communication unit includes an external connection terminal, a radio transmitter/receiver, a baseband processor, a communication controller and a handset. The buffer unit mounts at least one portable mobile telephone. The buffer unit includes a first buffer unit connector which is connectable to the external connection terminal of the communication unit, a second buffer connector which connects to a connector of a respective portable mobile telephone mounted on the buffer unit, an identifying mechanism for identifying the communication conditions of a respective portable mobile telephone mounted on the buffer unit, and a control signal transmitting mechanism for transmitting the communication conditions identified by the identifying mechanism to the communication controller of the communication unit. The communication controller is responsive to the transmitted communication conditions and adjusts the communication conditions of the communication unit so that a respective portable mobile telephone mounted on the buffer unit can communicate through the communication unit.

摘要： In a packet transmission system in which a plurality of kinds of telephone signals are packetized and transmitted, when a voice signal call is originated, a real channel is established for the voice signal call prior to a signal call other than a voice signal call, so that a transmission channel is occupied in each frame. When the voice signal call is over, the transmission channel allocated to the voice signal call, is changed to a condition in which another call can be allocated thereto. The system is useful for effective utilization of a packet communication network, without impairing the transmission quality requirement for a voice signal call.
