Abstract

PURPOSE:To attain access to a base station without being disturbed by a data signal while a request signal uses a reservation channel even at high traffic by splitting an incoming access channel into a reserved channel and a data channel. CONSTITUTION:An incoming access channel from a mobile equipment is split into a reserved channel 1-2 and a data channel 1-3. A mobile equipment going to access a base station uses a reply channel 1-1 to confirm that an idle line signal 1-8 is informed and sends a request signal 1-4 via the reserved channel 1-2. The base station receiving normally the request signal takes the operating state or the like of the channel 1-3 into account and sends a reply signal 1-6 via a channel 1-1. The mobile equipment receiving it sends immediately a data signal 1-7 via the channel 1-3. Thus, the channel efficiency of the incoming access channel is much improved at a high traffic (solid lines 3-1 in figure indicate the above channel efficiency).

(Prior art) In mobile communication, mobile device makes a call (random access)
In the conventional data slot reservation type air line control method, one way to control It is divided into two parts: a signal part and a data signal part. As shown in Figure 2, a mobile device attempting to access a base station first checks the idle signal 2-7 broadcast on the downlink response channel 2-1, and then attempts to access the base station via the uplink access channel 2-2. The base station then sends a request signal 2-4 and waits for a response from the base station. Upon receiving the request signal from the mobile device, the base station immediately changes the idle signal to a prohibition signal 2-3 and transmits a response signal to the mobile device that sent the request signal via the downlink response channel.

(Means for Solving the Problems) A feature of the present invention is mobile communication consisting of a base station and a plurality of mobile devices controlled by the base station, including an uplink channel from the mobile device to the base station and an uplink channel from the base station to the base station. In a system that has a control channel consisting of a downlink response channel for mobile devices, and in which each mobile device makes random access to a base station via the uplink channel as necessary, the uplink channel consists of an uplink reservation channel and an uplink data signal. The access control method has an access control method in which, when each mobile device makes random access to a base station, a request signal is transmitted via a reserved channel, and a data signal is transmitted to the base station via a data signal channel. .

(Operation) In the present invention, the conventional uplink access channel is divided into a reservation channel and a data signal channel in order to improve the channel efficiency of the uplink access channel especially during high traffic. As a result, even when data signals are frequently transmitted during high traffic, by using the reserved channel for request signals, it is possible to access the base station without being hindered by data signals.

2 and data signal channels 1-3. A mobile device attempting to access the base station first confirms that the idle signal 1-8 is being broadcast on the downlink response channel 1-1, and then transmits a request signal 1-4 via the reserved channel 1-2. do. The base station that has successfully received the request signal transmits the response signal 1-6 via the downlink response channel after considering the usage status of the data signal channel 1-3. Upon receiving this, the mobile device immediately transmits data signals 1-7 to the base station via data signal channels 1-3.

By using the reservation channel division type access restriction method according to the present invention, the prohibition signal that was conventionally broadcast when receiving a data signal becomes an idle line signal, so the time during which request signals can be accepted is extended even during high traffic. 《Access becomes easier. In addition, although dividing channels increases the number of control channels, the efficiency of data signal channels can be significantly improved through scheduling, and the number of downlink control channels does not need to be increased as much as uplink control channels. When compared with the case where the number of both upstream and downstream control channels is increased, it seems possible to considerably increase the channel efficiency of upstream access channels during high traffic as shown in FIG. In FIG. 3, 3-1 shows the channel efficiency characteristic according to the present invention, and 3-2 shows the channel efficiency characteristic according to the conventional technique.
