摘要： An object of the present invention is to reduce the control time required when a channel handover is performed in a mobile communication system. The conventional system has such shortcomings that a long time is required for re-designating a channel when a channel handover procedure results in failure. Particularly, in the common access type system, there is such a problem that since a channel handover is required to be performed several times during a channel handover procedure, an extra time is required for performing the handover procedure. The present invention has a plurality of base stations for covering the service area, and a mobile station for performing a communication with the base stations through radio channels. Here, the present invention is characterized in that the base stations notify the mobile station of a plurality of candidates when the mobile station performs a handover procedure, thereby improving the problem inherent in the conventional system that a single candidate is notified when a channel handover procedure is performed. Therefore, the present invention makes it possible to change the channel to the next candidate channel at high speed when the previous channel handover procedure results in failure.

摘要： This invention appropriately regulates or controls a simultaneous communication between different communication methods. When a request of a voice communication is made with respect to a communication terminal 4 which is currently busy with a packet communication from a communication terminal 1, a voice incoming signal is generated at a voice line controller 20. Then, a communication terminal state request is output from the voice line controller 20. This is transmitted to a data base 30 through a data exchange device 21. Then, the data base 30 reads voice line memory AB, packet line memory PB and transmits the same as a communication terminal state response to the voice line controller 20 through the data exchange device 21. As a consequence, the voice line controller 20 can know the communication state of the communication terminal 4 and determines whether or not the voice communication circuit should be connected based on it.

摘要： In a mobile communication system, a data communication fixed station 3 and a voice communication fixed station 4 control a common service area, the connection between a mobile station 5 and the data communication fixed station 3 can be quickened. The data communication fixed station 3 notifies, sequentially, the voice communication fixed station 4 of channel informations (e.g., usable channels, traffic quantity). The voice communication fixed station 4 receives the channel information via a broadcast channel for voice communication, and broadcasts the channel information to the mobile stations. When the mobile station 5 is to execute packet communication with an ISDN 1 via the data communication fixed station 3, the mobile station 5 selects an appropriate channel among the channels broadcasted thereto, and notifies the data communication fixed station 3 of the selected channel. As such, since the mobile station 5 can determine the channel before the actual communication between the mobile station 5 and the data communication fixed station 3 takes place, the connection between the mobile station 5 and the data communication fixed station 3 can be quickened.

摘要： A transmitted signal is enciphered or concealed to thereby prevent interference, even when data indicative of the receiver terminal is made public because of the use of a common access channel. In the transmitter, in a random-number bit adder 6, a random-number .alpha. (digital signal) generated by a random-number generator 5 is inserted into a transmitting data signal DA generated by a transmitting data generator 1, and the resultant is outputted as a signal (DA, .alpha.). An encipherment processor 2 enciphers the signal (DA, .alpha.) and outputs it as a signal (DA, .alpha.)'. In the receiver, this signal (DA, .alpha.)' is deciphered into (DA, .alpha.), and the random-bits .varies. are removed from (DA, .alpha.) to restore the signal DA.

摘要： A mobile communication fixed station 101 transmits significant data to a mobile station 103 (104) after holding the significant data for a predetermined time, and no significant data are transmitted to the mobile station during that time. When there are no significant data which are being held, the fixed station 101 transmits remaining time data indicative of the predetermined time to the mobile station, and no significant data are transmitted to the mobile station. When significant data is being held, time data indicative of the remaining time until the start of transmission of the significant data is transmitted to the mobile station in each slot from the time significant data occurs until the time the significant data is transmitted. The fixed station 103 , which has received the remaining time data stops receiving for a time interval corresponding to the remaining time.

摘要： A transmittal signal is transmitted in a forward error correction format in case the length of the transmittal signal satisfies predetermined conditions but not in a forward error correction format in case the length of the transmittal signal does not satisfy the predetermined conditions. Owing to this arrangement, a long signal susceptible to errors, can be encoded in a forward error correction format. For transmitting a short transmittal signal, wasteful consumption of transmission data capacity of a radio channel can be prevented.

摘要： When data is transferred by using a plurality of time slots, the transferring period is shortened by adopting priority to assign the required number of slots. The base station BS which accepted packet P1 generates a "BUSY" signal and an echo at the final portion of the first time slot TS which begins at time t4. The base station BS, recognizing that there is a packet following the packet P1, generates a "RESERVED" signal at the final portion of the time slot TS which begins at time t5. The mobile station MS-A learns that the first time slot is assigned by recognizing the "BUSY" signal and the echo, and that the second time slot is also assigned by recognizing the "RESERVED" signal. Therefore, the first and second time slots are used successively for fast transferring.

摘要： Base station generates a mobile station identifier which indicates a mobile station that a data signal is addressed thereto, and a head slot having a data signal when there is a data signal that has a length to be able to transmitted using one slot of a TDMA radio channel. When there is a data signal that has a length to be not able to transmitted using one slot, base station generates a head slot and continuous slots which contain at least a part of data signal. Base station transmits the head slot by using the starting slot which located at predetermined position every mobile station on the TDMA radio channel, and transmits the continuous slots by using slots which follow the starting slot. Mobile station receives the starting slot, and stops reception if the starting slot is not the head slot. If the starting slot is the head slot, the mobile station judges the mobile station identifier. Furthermore, if the mobile station identifier indicates other mobile station, the mobile station stops reception, on the other hand, if the mobile station identifier indicates itself, the mobile station receives the continuous slot.
