DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication control technique in a communication network formed by connecting to, for example, a local exchange or a transit exchange constituting a public network.
The present invention relates to a communication control method and apparatus in a wireless subscriber network using a WLL (Wireless Local Loop) system.

[0002]

2. Description of the Related Art PHS is one of mobile communication systems.
(Personal Handy-phone System). In PHS,
A plurality of subscriber exchanges each accommodating a plurality of subscriber terminals via a subscriber line, a common line signal network for control signal transmission connecting the plurality of subscriber exchanges, and the plurality of subscriber exchanges, or A plurality of base stations for communicating with a mobile terminal via a wireless channel in a digital network formed by connecting the plurality of local exchanges via a relay exchange and a communication path network for transmitting user information. Is connected to the above-mentioned local exchange via a digital line.

According to the above PHS network configuration,
When there is a call request to a mobile terminal by the PHS from an existing subscriber terminal, a signal notifying the response of the mobile terminal is transmitted from the mobile terminal to the subscriber accommodating the corresponding subscriber terminal via the common channel signal network. Sent to the exchange.

[0004] There are cases where the above-mentioned local exchange transmits a signal notifying the response of the mobile terminal to the subscriber terminal and a case where the signal is not transmitted. This depends on the functions provided in the local exchange used, and some exchanges do not transmit any response signal from the originating local exchange to the originating terminal in order to reduce the size and cost.

In the above PHS network configuration, even when a signal notifying the response of the mobile terminal is not transmitted from the subscriber exchange to the subscriber terminal, the subscriber exchange establishes a communication path between the subscriber terminal and the digital network. Once set, you can talk. Furthermore, since there is no processing that occurs in response to the reception of a signal notifying the response of the called terminal, no problem occurs even if the received signal is not received by the subscriber terminal.

On the other hand, when a call request is issued from the mobile terminal to the subscriber terminal, a signal notifying the response of the subscriber terminal is similarly transmitted from the subscriber terminal to the subscriber exchange accommodating the subscriber terminal.
And, it is transmitted to the base station accommodating the mobile terminal via the common channel signal network. The base station that has received the above-mentioned signal sets up a two-way communication path and always transmits a signal for notifying the mobile terminal of the response of the general subscriber to the mobile terminal via the wireless channel.

In recent years, in a conventional communication network,
By introducing technologies and devices used in mobile communication systems such as PHS into a subscriber line (access equipment) for accommodating subscriber terminals in a subscriber exchange,
Studies are underway to construct a subscriber telephone service economically. This is a system in which access equipment is configured in a wireless manner, and is called a WLL (wireless local loop).

In the conventional WLL, a base station for communicating with a WLL subscriber station via a radio channel is connected to a subscriber exchange constituting the digital network via a subscriber line. A wireless subscriber network controller having a signal conversion function is disposed between the wireless subscriber network controller and the local switch, and a wireless communication network is provided between the wireless subscriber network controller and the base station. The network is connected by a digital line, and a signal conversion function is arranged in a WLL subscriber station, and a subscriber terminal is connected via the subscriber line.

Further, in the above-mentioned conventional WLL configuration, W WLW is connected between the wireless subscriber network controller and the local exchange.
An analog subscriber line is used between the LL subscriber station and the subscriber terminal.

[0010]

However, the conventional W
According to the LL network configuration, as in the case of the PHS, when a call request from a subscriber terminal is accepted by the wireless subscriber network controller, the local exchange is switched from the local exchange connected to the digital network to the wireless subscriber network. There are cases where a signal notifying the response of the receiving side is transmitted to the control device and cases where it is not transmitted.

In a WLL network, a service equivalent to that of a conventional communication system is provided to a subscriber terminal connected to a WLL system and a subscriber terminal directly connected to a subscriber exchange via a subscriber line. Therefore, in the above case, the WLL subscriber station does not need to transmit a signal for notifying the subscriber terminal of the response on the receiving side. However, if the signal notifying the response of the receiving side is not notified, it becomes a trigger for setting a digital line between the wireless subscriber network controller and the WLL subscriber station and a communication channel of the wireless channel. There is a problem that there is no information and a call path cannot be set.

Further, if the signal notifying the response of the called party is not received by the wireless subscriber network control device, the call information collection processing in the wireless subscriber network control device, which is performed in the conventional communication control technology, is performed. There is no trigger for starting, and there is a problem that call information collection processing cannot be started.

An object of the present invention is to provide a communication control method capable of realizing a communication service equivalent to that of a conventional subscriber terminal even for a subscriber terminal connected to a WLL system, a wireless subscriber network control apparatus according to the method, and , A wireless subscriber network comprising the device.

More specifically, even when a signal for notifying a response of the called party is not transmitted from the local exchange to the wireless subscriber network controller, the response of the called party is notified to the base station; Alternatively, it is another object of the present invention to provide a wireless subscriber network control device including a unit that enables collection of call information.

Another object of the present invention is to provide a communication network having an access node connected to an existing subscriber exchange via a subscriber line, informing the access node from the subscriber exchange of a response on the receiving side.
