【発明の詳細な説明】 〔産業上の利用分野〕 本発明はパケットデータ伝送方式に関し、特に移動端
末局と基地局との間のデータ授受を行うパケットデータ
伝送方式に関する。The present invention relates to a packet data transmission system, and more particularly to a packet data transmission system for exchanging data between a mobile terminal station and a base station.

グ部とデータ部に分かれている。Conventionally, in a packet transmission method of mobile radio communication, a polling method between a base station and a mobile terminal (hereinafter referred to as a terminal) is a call invitation invitation polling signal P issued from the base station as shown in the second (a) format diagram. = 0, P = 1, P = 2 are output, and, for example, the poll number P # 1 given to the specific terminal # 1 currently communicating is sending the uplink data to the base station. In this figure, the terminal first makes a call request at P = 0 of the base station, and the terminal given the poll number # 1 at P # 1 has transmitted uplink data. FIG. 2B shows the signal structure of the downlink slot from the base station, which is divided into a polling section and a data section.

する指示信号がなかった。Next, the exchange of signals and data between the base station and the terminal station will be described with reference to the sequence diagram of FIG. First, the terminal A makes a call request, the base station accepts the call, and sends a solicitation P # n to the terminal, and sends data D ( 0 ). After receiving the data of D 0, the base station sends P # n again to the terminal A, and the last packet data D
If (n) is present, the last packet data (Dn) is sent from the terminal A, but when the data reception is completed, the base station immediately sends the transmission right reversal instruction signal P # nRV to the terminal A,
The transmission right is transferred to the base station. When data is sent from another remote terminal B to the terminal A via the base station, the data D of the terminal B is transmitted.
( 0 ) and D ( 1 ) are sent to the terminal A, but when the data of the terminal B has not arrived, the base station instructs the terminal A to cancel the temporary reception waiting due to the traffic congestion of the terminal A. There was no signal.
上述した従来のパケットデータ伝送方式は、移動端末

方は基地局のデータ受信待ちの状態となり、例えば基地

し、端末局の受信待ちの一時解除ができない欠点があっ
た。In the conventional packet data transmission method described above, when the mobile terminal station transfers the data transmission right to the base station, the mobile terminal station waits for the data reception of the base station, for example, data does not arrive at the base station. Due to the delay in data transmission due to the above, there is a drawback that the terminal station cannot temporarily cancel the reception waiting.

段とを有する。The packet data transmission method of the present invention is a packet data transmission method in which half-duplex data communication is performed with a plurality of terminal stations via a base station by polling, wherein the base station receives all data from the terminal station A. After that, if the response data of the terminal station B of the communication partner has not reached the base station yet, the base station outputs to the terminal station A a wait signal for temporarily canceling the response data reception waiting; The base station has means for outputting a signal for acquiring transmission right to the terminal station A when the response data of the station B arrives.
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 described with reference to the drawings.

パケットデータ伝送方式が実現できる。FIG. 1 is a sequence diagram of an embodiment of the present invention. When a call is made from the terminal A side and the call is accepted by the base station side, the terminal A side sends all data D ( 0 ) to the base station in response to the transmission invitation P # n from the base station. Base station is terminal A
After receiving the last packet D (n) data from the terminal, the wait signal P # nW is transmitted to the terminal A. In this wait signal, when the base station receives all the data from the terminal A and then the base station side tries to transmit the data from the terminal B, but the data from the partner terminal B has not reached the base station yet. Etc. When the data reception of the terminal B is completed, the base station sends the transmission right inversion instruction signal P to the terminal A.
#NRV is issued and data D ( 0 ) and D ( 1 ) from terminal B
To terminal A. In this way, the base station sends a temporary wait signal to the terminal before the transmission right is transferred from the specific terminal, thereby realizing a packet data transmission method in which the terminal does not need to keep waiting in an unnecessarily manner.

効果がある。As described above, the present invention has an effect of transmitting the wait signal from the base station to the terminal, so that the terminal station is not restricted in the state of waiting for data reception. Also, until the transmission right reversal instruction is received from the base station side, the polling control unit is received instead of the data reception mode, so that different control information and the like can be exchanged with the base station. effective.
