た。Conventionally, in the packet transmission system of mobile radio communications, the polling method between a base station and a mobile terminal (hereinafter referred to as a terminal) uses a call solicitation polling signal issued from the base station, as shown in the format diagram 2 (a). P=O, P=1, P=
2 is output, and for example, ball number P#1 given to specific terminal #1 currently communicating is sending uplink data to the base station. In this figure, a terminal first makes a call request at P=O of the base station, and the terminal, which is given ball number #1 at P#l, transmits uplink data. Figure 2(b) shows the signal structure of the downlink slot from the base station, which is divided into a polling part and a data part.Next, the signals and data exchange between the base station and the terminal station will be explained using the sequence diagram in Figure 3. do. First, terminal A requests a call, the base station accepts the call, sends an invitation P#n to the terminal, and then sends data D(o). After receiving the Do data, the base station sends P#n again to terminal A, and if there is last packet data D (n), terminal A sends the last packet data (Dn), but when the data reception is finished, the base station Immediately, a transmission right reversal instruction signal P#nRV is sent to terminal A, and the transmission right is transferred to the base station. Now, when sending data from another terminal B to terminal A via the base station, terminal B's data D(o) and D(1) are sent to terminal A, but terminal B's data has not yet arrived. In this case, the base station did not send an instruction signal to terminal A to temporarily release the reception standby state due to traffic congestion.
上述した従来のパケットデータ伝送方式は、移動端末局

でのデータ未到着等によるデータ送信おくれ等に対し、
端末局の受信待ちの一次解除ができない欠点があった。In the conventional packet data transmission method described above, when the right to transmit data is transferred from the mobile terminal station to the base station, the mobile terminal station enters a state of waiting for data reception from the base station.For example, if the data does not arrive at the base station, etc. Regarding delays in data transmission due to
There was a drawback that it was not possible to temporarily release the terminal station from waiting for reception.

とを有する。The packet data transmission method of the present invention is a packet data transmission method in which half-duplex data communication is performed between a plurality of terminal stations via a base station by polling, and the base station receives all data from terminal station A. means for outputting a wait signal to the terminal station A to temporarily release the waiting state for receiving the response data, if the response data of the communication partner terminal station B has not yet reached the base station after the response data has been received; When the response data from station B is received, the base station has means for outputting a signal to the terminal station A to obtain a transmission right.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

いパケットデータ伝送方式が実現できる。Figure 1 is a sequence diagram of one embodiment of the present invention. When a call is made from the terminal A side and the call is accepted by the base station, the terminal A side sends all data D(o) to the base station in response to a transmission invitation P#n from the base station. When the base station finishes receiving the last packet 1·D(n) data from terminal A, it transmits a wait signal PlnW to terminal A. This wait signal is sent when the base station receives all data from terminal B and then tries to transmit data from terminal B, or when data from terminal B on the other side has not yet reached the base station. etc. will be sent. When terminal B completes data reception, the base station sends a transmission right reversal instruction signal P to terminal A.
#nRV and data D(o) from terminal B. D(+
) is sent to terminal A. In this way, by sending a temporary wait signal to a terminal before the base station transfers the transmission right from a specific terminal, a packet data transmission system can be realized in which the terminal does not need to remain in a waiting state unnecessarily.

果がある。As explained above, the present invention has the effect that by sending a wait signal from the base station to the terminal, the terminal station is no longer restricted to the state of waiting for data reception. In addition, until the transmission right reversal instruction is received from the base station, the polling control unit is received without entering data reception mode, so other control information etc. can be exchanged with the base station. effective.
