Description

Detailed Description of the Invention

[0001]

The present invention relates to a wireless local loop (WLL) terminal, a WLL base station connected to a WLL terminal by a wireless line, and a switching center to which the WLL base station is connected. A configured wireless communication system.

[0002]

2. Description of the Related Art A general radio base station connects to a mobile station via a radio line and to a fixed station via a wire line.

[0003] In addition, there is an answering machine service as a network service in a mobile phone or the like, which can record and listen to information such as messages, but it is hard-pressed for each subscriber so that any subscriber can access it. You cannot do it. Further, although there is an information providing service, the information provider is on the business side, and the service that the subscriber provides the information is not provided.

[0004]

Information closely related to the area includes, for example, circular boards, bulletin boards, newspaper advertisements, etc., but few are digitized.

On the other hand, the WLL base station used as a wireless communication means is installed in each region, but its purpose is only to construct a communication area for communicating with the WLL terminal. Yes, it does not support the information transmission services rooted in the above areas.

An object of the present invention is to realize a wireless communication system capable of transmitting information to subscribers by providing a means for storing information closely related to a region in a WLL base station used as a wireless communication means.

[0007]

According to the present invention, WLL is used.
Terminal connected to the WLL terminal by a wireless line
In a wireless communication system composed of an LL base station and an exchange station to which the WLL base station is connected,
This is realized by incorporating a storage device for storing voice and data in the LL base station in addition to a control storage device for controlling the device.

According to the present invention, it is possible to provide local information only in a specific area covered by the WLL base station. Moreover, since the existing network can be used, the service can be realized at low cost.

1 to 4 are explanatory views showing an embodiment of the present invention.

FIG. 1 is a block diagram showing the system configuration of the present invention and the configuration of a WLL base station.

In FIG. 1, 101 is a base station for WLL and 10
A wireless unit 2 communicates with a WLL terminal 108 via a wireless line 110 through an antenna 107, and includes a receiving circuit and a transmitting circuit.

Reference numeral 103 denotes a wired section for communicating with the exchange 109 via a wired line 111. Reference numeral 104 denotes a control unit that controls the operation of each unit and is configured by a microcomputer. A recording device 105 records audio data. 1
Reference numeral 06 is a storage device that stores data necessary for performing a service.

FIG. 2 shows a general subscriber telephone to a base station 1 for WLL.
11 is an example of a sequence for recording to the recording device 105 of No. 01. The WLL base station 101 has a telephone number, and a person who wants to provide information can make a call from a general subscriber telephone to the WLL base station 1
Call 01. Of course, the information can be provided from the WLL terminal 108. The information provider is P
The service type is selected by the B signal or the like, and then the message is transmitted in the same manner as recording on the answering machine. WL
In the L base station 101, the service type is stored in the storage device 106.
The recording message is stored in the recording device 105. In this way, the message is registered in the WLL base station 101.

3 and 4 show WLL base station 101 to W.
It is an example of a sequence when providing service information to the LL terminal 108.

FIG. 3 shows a sequence in a system in which the WLL base station 101 constantly broadcasts service information. When the user wants to obtain information, the WLL terminal 10
8 to transmit a service request to the WLL base station 101. When the WLL base station 101 receives the service request, the WLL terminal 108 accepts the service request.
Send to Then, after the WLL terminal 108 side receives the service request acceptance, an authentication process is started between the WLL terminal 108 and the WLL base station 101. When the user receives the service, the subscriber data is registered in advance and W
Data is stored in the storage device 106 of the LL base station 101. The WLL base station 101 inquires of the storage device 106 for subscriber data of the WLL terminal 108 during the authentication process, and when the authentication is completed, transmits a signal permitting the service to the WLL terminal 108. Although the service information is always transmitted from the WLL base station 101, the contents of the information should not be known to the terminal that does not know the secret key due to the secret communication function. The service permission signal transmitted from the WLL base station 101 includes the channel information for which the service information is broadcast and the secret key information for releasing the confidential communication. On the WLL terminal 108 side, the confidential information is released from the received service information using the secret key specified in the service request, and the information is given to the user. When the user finishes acquiring the information, the WLL terminal 108 performs an end call operation, notifies the WLL base station 101 of the service end from the WLL terminal 108, and the WLL base station 101 transmits a service end acceptance, The radio channel is disconnected.

FIG. 4 shows a sequence of a system in which several kinds of services are prepared on the WLL base station 101 side and the services are selected by the WLL terminal 108. The sequence up to the authentication process is the same as the sequence shown in FIG. When the authentication process of the WLL terminal 108 is completed, the WLL base station 101 transmits a service permission signal. In this case, the service permission signal contains information on the options of the specific service, and the WL which received the signal.
The L terminal 108 can be selected. Therefore,
When the user selects a service, the WLL terminal 108 transmits a specific service designation signal to the WLL base station 101, and starts transmitting the service information designated on the WLL base station 101 side.

[0017]

According to the present invention, information can be provided and obtained only in the local area covered by the WLL base station.
