Delay correction system for wireless telephone system

A delay correction system for a wireless telephone system in which a base station apparatus and at least one subscriber apparatus carry out transmitting and receiving operations via respective communication means, in conformance with a time division multiple access (TDMA) system using the base station apparatus as a synchronization reference, said delay correction system comprising:

• measuring instruction input means for inputting a delay measuring instruction which instructs a delay measurement;
• delay measuring means for measuring a delay quantity between the base station apparatus and the subscriber apparatus;
• and
• time slot correcting means, provided in the base station apparatus, adjusting a time position of a signal received from the subscriber apparatus depending on the delay quantity, and moving the time position of the received signal to an appropriate time slot.

A delay correction system for a wireless telephone system in which a base station apparatus and at least one subscriber apparatus carry out transmitting and receiving operations, in conformance with a time division multiple access (TDMA) system using the base station apparatus as a synchronization reference, said subscriber apparatus comprising:

• communication means for transmitting and receiving signals with respect to the base station apparatus;
• communication control means for controlling the operation of said communication means in conformance with the TDMA system;
• second timing adjusting means for receiving transmitting information which is to be sent to the base station apparatus and adjusting a transmission timing depending on an adjusting value which is specified by an input adjusting instruction;
• establishment request means for repeatedly instructing said communication control means that a link channel establish request is issued;
• transmission timing search means, which starts to operate depending on a transmission of the link channel establish request by said communication control means, for changing the adjusting value depending on whether or not said communication means received a response corresponding to the link channel establish request, and for transmitting the adjusting instruction which specifies the adjusting value to said second timing adjusting means;
• and
• channel allocation monitoring means for monitoring exchange of signals between said communication means and the base station apparatus, and stopping an operation of said establishment request means depending on a detection of a response corresponding to the link channel establish request.
