Abstract
Abstract In a TDMA radio communication system consisting of a master station and a plurality of slave stations, the master station performs channel control for sending time slot assignment information to only a calling slave station in response to a time slot assignment request from a calling slave station. The calling slave station performs transmission control. In this control, the calling slave station detects an address of a destination device from an input transmitting signal, determines a called slave station based on the detected address, adds the address of the called slave station to the input transmitting signal to form a transmission signal, and inserts the transmission signal in the assigned time slot.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
383 words
A time division multiple access radio communication system comprising a master station, a plurality of slave stations, and a time division multiple channel connecting between said slave stations under control of said master station, said master station comprising: channel connection control means for receiving a channel connection request from a calling slave station, determining based on availability of said channel whether or not the channel can be assigned, and transmitting a response signal to said calling slave station by adding the determination result to the response signal; channel control means for receiving a slot assignment request from the calling slave station and transmitting slot assignment information of said time division multiple channel to said calling slave station; and release means for receiving a disconnection request from the calling slave station and releasing assignment of a slot assigned to the calling slave station; each of said slave stations comprising: channel connection request means responsive to an input calling signal to perform the channel connection request to said master station; slot assignment request means for receiving an acknowledge signal for the channel connection request from said master station and sending the slot assignment request to said master station; slot detection means for detecting a slot assigned to said slave station as the calling station based on the received slot assignment information; address detection means for detecting an address of a destination device based on an input transmitting signal; called station determination means for determining a called slave station based on the address of said destination device detected by said address detection means; transmission control means for adding an address of said called slave station determined by said called station determination means to the input transmitting signal to form a transmission signal, and inserting the transmission signal into the time slot detected by said slot detection means; reception control means for receiving the transmission signal inserted in each time slot of the time division multiple channel to detect the address of said called slave station included in each transmission signal, and fetching the transmission signal in which the address of said called slave station coincides with that of its own as a reception signal; and completion control means for transmitting the disconnection request in response to completion of the transmission operation of said transmission control means.
Claim 2
Dependent Claim
383 words
A time division multiple access radio communication system comprising a master station, a plurality of slave stations, and a time division multiple channel connecting between said slave stations under control of said master station, said master station comprising: channel connection control means for receiving a channel connection request from a calling slave station, determining based on availability of said channel whether or not the channel can be assigned, and transmitting a response signal to said calling slave station by adding the determination result to the response signal; channel control means for receiving a slot assignment request from the calling slave station and transmitting slot assignment information of said time division multiple channel to said calling slave station; and release means for receiving a disconnection request from the calling slave station and releasing assignment of a slot assigned to the calling slave station; each of said slave stations comprising: channel connection request means responsive to an input calling signal to perform the channel connection request to said master station; slot assignment request means for receiving an acknowledge signal for the channel connection request from said master station and sending the slot assignment request to said master station; slot detection means for detecting a slot assigned to said slave station as the calling station based on the received slot assignment information; address detection means for detecting an address of a destination device based on an input transmitting signal; called station determination means for determining a called slave station based on the address of said destination device detected by said address detection means; transmission control means for adding an address of said called slave station determined by said called station determination means to the input transmitting signal to form a transmission signal, and inserting the transmission signal into the time slot detected by said slot detection means; reception control means for receiving the transmission signal inserted in each time slot of the time division multiple channel to detect the address of said called slave station included in each transmission signal, and fetching the transmission signal in which the address of said called slave station coincides with that of its own as a reception signal; and completion control means for transmitting the disconnection request in response to completion of the transmission operation of said transmission control means.
Claim 3
Dependent Claim
33 words
A system according to claim 1, wherein said transmission control means of each of said calling slave stations causes an address of its own to be included in the transmission signal formed thereby.
