    • PURPOSE:To attain user-friendly communication for a called party by providing a physical number for each terminal equipment, a logical number for each talking party, a means receiving urgency, a means discriminating the reception method and a means for discrimination and required reception processing to a communication network or a terminal equipment. CONSTITUTION:A caller inputs a called party number (physical number or logical number) and emergency designated by the caller for the communication. The information is sent to a network via a user network interface 10 and received by a reception section 2 through a channel 7. On the other hand, a called party enters intention information from its terminal equipment 4 at the arrival of a call or in advance. The intention information and the called party number are sent to the network via a user network interface 11 and registered by a registration section 3 through a channel 3. A discrimination section 5 decides the connection method from the received information and the registered information and a processing section 6 makes required incoming processing relating to a channel 9. Thus, the reception method of the communication reflected on the intention of the called party is selected and the user-friendly communication for the called party is attained.

    • PURPOSE:To reduce the change of transfer capacity required for a radio section when the moving speed of a mobile station changes by setting the dimension of the position registration area in advance corresponding to the speed of each mobile station. CONSTITUTION:When moving at the moving speed corresponding to a mobile station 41 and a high-speed mode A, the position registration is performed in positions 52/53/54 where the information contents of a time slot changes accompanied by the movement of the movile station 41. When the station 41 transfers a position registration request signal to a radio base station, the position registration area where the mobile station exists is discriminated in the radio base station while adding the information indicating the performance of the position registration based on the position registration discrimination signal of the mode A. When the mobile station 41 moves at the moving speed 51 of a low-speed mode B, the position registration is performed only in the position 53 where the information contents of the time slot changes accompanied by the movement of the mobile station since the station 41 refers to the only time slot corresponding to the mode B.

    • PURPOSE:To efficiently offer various fine service areas by hierarchally constituting the service areas in the transmission area of a message to a personal terminal, the reception area of a response from the personal terminal, the transmission/reception area of the message from the personal terminal and the transmission/reception area of a sound. CONSTITUTION:A radio zone is hierarchally constituted and an A zone is provided only for a call, namely, as a zone only for receiving the message. A B zone is a zone to which only the simple response (ACK) reception is added to the A zone, and a C zone is a zone to which the message transmission/ reception is added to the B zone. Further, a D zone is a zone to which the sound transmission/reception is added to the C zone. Then, the communication area is made various according to the service area based on the function provided for a personal terminal 11 and the position where the personal terminal exists. On the other hand, based on information stored in base stations 15 and 16, the personal terminal is retrieved corresponding to a telephone number to be dialed by a communicating person, and the communication area suitable for the personal terminal 11 is selected. Thus, the various fine service areas can be efficiently offered.

    • PURPOSE:To permit the owner of a terminal to learn an incoming call, and on the other hand to prevent the sound of the incoming call from putting surrounding people to trouble by automatically altering an incoming display sound volume in accordance with the level of a sound volume in peripheral environment at the time of the incoming call. CONSTITUTION:A sound volume decision and sound/light switching control part 13 selects the method of displaying the incoming call. It selects display by light emission or the incoming display sound of a micro sound volume when the level is in a silence state, and a maximum sound volume when it is the sound volume to the degree of the inside of a subway in accordance with the level of the sound volume measured in a peripheral sound volume measurement part 12 (classification into several sound volume tanks such as silence state, sound volume to degree that several people are in the middle of conversation, sound volume to degree on the street where the traffic is heavy, and sound volume to degree of the inside of the subway, for example, is executed).

    • PURPOSE:To enable a response signal to be sent to a called station and to perform routing to a caller by attaching the identification number of the called station when response from a personal terminal is performed. CONSTITUTION:A TE 15 dials a (specific number + PIDNo), and an LS/TS 16 receives it and connects a line to a PMSC 17, and a (PS call + PIDNo) is sent to the PMSC 17. The PMSC 17 calls a PS 11 via a PMBS 13. At this time, a signal is sent by imparting the identification signal PMBSNo representing a called PMBS to the call signal of the PS 11. A called PS 11 is moved up to the nearest communication zone of a PSBS and returns the response signal imparting the PMBSNo. A PSBS 12 is attached on the response signal, and relays the response signal to a correspondent PMBS 13. The PMBS 13 receives it, and relays it to the PMSC 17. Simultaneously, a PSBS 14 sets a communication channel between the PSBS 14 and the PS 11 in parallel, and sends a communication channel setting completion signal to the PMSC 17. The PMSC 17 sets a communication line between the caller (TE 15), then, calls the caller.

    • PURPOSE:To automatically compensate a procedure error even when the procedure error occurs due to a transmission error, etc., so as to improve the transferring efficiency by previously storing communication histories of opposite communication equipment after classification at every equipment, and when communication abnormality occurs, correcting wrong information by using the histories. CONSTITUTION:A procedure storage circuit 115 stores the history of the past communication procedure (procedures and their occurring frequencies) until the present time of opposite communication equipment at every equipment. When an abnormality detection circuit 114 detects abnormality, a procedure estimation circuit 116 estimates the abnormal point and infers the most frequent information (the data having the highest abnormality occurring probability among those having the shortest inter-pattern distance after performing pattern matching with the past communication histories of the circuit 115). After inference, the circuit 116 transmits the information to a procedure compensation circuit 117. While the circuit 117 transmits the information of a data link control circuit 113 to a network level call connection control circuit 118 as it is, but, when abnormality is detected, the circuit 117 replaces the information of the circuit 113 with that of the circuit 116. Thus wrong information can be corrected and, at the same time, omitted information can be supplemented.
