摘要： PURPOSE:To attain high speed tuning during tuning of talking channel for idle talking channel search by switching a loop band in a PLL frequency synthesizer so that the band is wider in the control channel tuning that the talking channel tuning. CONSTITUTION:During the tuning for idle channel search, a loop band is set to a maximum value A. Thus, whether or not each speech channel is idle is discriminated in a short time. Moreover, during standby of control information or during reception of control information, the loop band is set to an intermediate value B. Then the control information is surely received even while switching in a comparatively short time. Furthermore, the loop band is set to a minimum value C during the talking. Then sufficient voice quality is ensured during the talking.

摘要： PURPOSE:To proceed the processing for an incoming call from a wire telephone line without increasing the number of PB signal receivers by transmitting the non-response of a mobile radio equipment or the setting failure of a radio line to a communication control unit at the signal mode different from a PB signal. CONSTITUTION:When a PB signal receiving circuit in a communication control unit 7 is closed, for example, a fixed radio equipment 41 transmits an incoming call non-response informing signal in the signal mode to change the timing between loops, for example, in accordance with the presence and absence of the response of a mobile radio equipment 3a. Consequently, even when the PB signal receiving circuit is closed by the communication control unit 7, the response condition of the mobile radio equipment 3a is identified by the timing between loops and shifting can be executed to the suitable incoming call processing in accordance with the presence and absence of the response. Thus, without increasing the PB signal receiving circuit, the processing for the incoming call non-response of the mobile radio equipment can be executed.

摘要： PURPOSE:To improve the effective utility of a radio line by constituting the titled system such that a 1st mode sending a position notifying signal and a 2nd mode not sending the signal are provided and both the modes are repeated at a proper period. CONSTITUTION:The position notifying signal is sent in setting the 1st mode. At the time of setting the 2nd mode, the signal transmission/reception from a pole changing signal to a bipolar signal are applied only between the line controller 7 and stationary radio equipment and no position notifying signal is sent. Thus, the 2nd mode is used much more than the 1st mode and both the modes are selected at a proper period, then the use of a radio line not directly relating to the call is reduced and the effective utilization of the radio line is improved.

摘要： PURPOSE:To reduce the traffic of a control radio frequency at non- communication by sending a position information request signal from a mobile radio equipment and allowing a stationary radio equipment receiving the said position information request to send position information at a predetermined time. CONSTITUTION:When a mobile radio equipment 11b sends a position information request signal, since the radio equipment 11b belongs to radio zones 9a, 9b, stationary radio equipments 7a, 7b receive it. Thus, the stationary radio equipment 7b informs the position information at a prescribed time. Moreover, when the stationary radio equipment 7b informs the position information at a prescribed time (different time from that for the radio equipment 7b). On the other hand, the mobile radio equipment 11b receives the position information generated by the stationary radio equipments 7b, 7a, selects the stationary radio equipment depending on the strength of a radio wave by itself to detect its own position. Then the mobile radio equipment 11b revises the position registration to the exchange 1 via the stationary radio equipment to be selected.

摘要： PURPOSE:To contrive to improve the position registration accuracy of a mobile radio equipment by detecting the position of its own equipment when a connection control signal from a stationary radio equipment to other mobile radio equipment is sent and informing the result of detection to a private branch of exchange via the stationary radio equipment being a sender to register the result. CONSTITUTION:A mobile radio equipment consists of a transmission section 82 and a reception section 84 transmitting/receiving a signal with a stationary radio equipment, a synthesizer 85 and a control section 86. A position detection means 86a in the control section 86 detects the position of its own equipment, that is, the radio zone where its own equipment exists from an ID code of the stationary radio equipment being the sender inserted in the signal. Then a position registration control means 86c sends a position registration request signal to a private branch of exchange via the stationary radio equipment while discriminating it as the movement of its own equipment to other radio zone if the detected position differs from the present registered position to revise the registered position information so far into new position information.

摘要： PURPOSE:To shorten connection delay, by issuing a signal to designate a fixed station which relays its own transmission signal from a mobile station, and making a control station relay the transmission signal from the mobile station only to a designated fixed station. CONSTITUTION:The mobile station transmits the identification code ID(A) of the fixed station to relay the transmission signal of its own station and the identification code ID(B) of its own station behind a preamble and a frame synchronizing signal FS, and next, transmits a required control signal. The transmission signal including such identification ID(A) from the mobile station is received by plural fixed stations near the mobile station. However, only the fixed station having a number which coincides with the identification ID(A) responds, and continues a required processing for the control station. Therefore, the fixed station is not requested to detect reception electric field strength from the mobile station, and also, the control station is not requested to perform a processing to select the fixed station, and a means to process such operation is not required. In such a way, it is possible to reduce the connection delay to the minimum.

摘要： PURPOSE:To prevent the deterioration in the speech quality by comparing a reception level of a position notice signal received from a stationary radio equipment whose position is already registered and from other stationary radio equipment and revising the registered position when the reception level of the latter is larger by a prescribed value or over. CONSTITUTION:After a notice monitor timer is set, e.g., a mobile radio equipment 3a checks whether the position notice signal is received from a stationary radio equipment 41 or other stationary radio equipments 41, 42 when the position notice signal with a prescribed level or over is received from any of the stationary radio equipments 41-43. Then the position notice signal from other stationary radio equipment is checked as to whether it is received at a larger level by a prescribed level or over than the signal from the stationary radio equipment registered already. When the level is received by a larger level with a prescribed value or over, since it represents that the stationary radio equipment moves to a new radio zone, the registered position is revised. Thus, the production level of a disturbing wave due to transmission or reception intermodulation is decreased to ensure the required speech quality.

摘要： PURPOSE:To improve the service to a user by allowing a mobile radio equipment to supervise the arrival of a position notice signal from each stationary radio equipment and notifying it in a prescribed alarm tone if the mobile equipment cannot receive a position notice signal from any stationary radio equipment at a prescribed level or over within a prescribed time. CONSTITUTION:If a notice supervisory time expires, a mobile radio equipment 3a checks whether or not a position notice signal from a stationary radio equipment 41 or other stationary radio equipments 42, 43 is received before the expiration. If the position notice signal with a prescribed level or over from any stationary radio equipment is not received, the mobile radio equipments is decided to be located at the outside of the zone to any stationary radio equipment. Then an alarm tone representing it is generated. Thus, even if the connection by the call operation is failed, the user can simply discriminate the failure because the cause is due to the location of out of zone originally and the mobile equipment can make an incoming/outgoing call by moving the equipment 3a to the out of zone.

摘要： PURPOSE:To increase a processable traffic quantity by registering a fixed radio equipment with a high receiving level to a communication control unit when a position informing signal from a fixed radio equipment except the registered fixed radio equipment is received by the receiving level higher than the prescribed receiving level. CONSTITUTION:When a radio zone 51 of a position registered fixed radio equipment, for example 41, is only one and the position informing signal from other fixed radio equipment 42 is also received over a prescribed level, it is considered that a mobile radio equipment 3a exists at the position where at least two radio zones 51 and 52 are superimposed. By registering these two radio zones 51 and 52, the radio line can be composed of at least two channels. Thus, the traffic quantity can be increased in which the processing as a system can be performed.
