Description

Description: TECHNICAL FIELD The present invention relates to an information service system in mobile communication.

(Problems to be Solved by the Prior Art and the Invention) Generally, as an information service system in the current mobile communication, a connection to a public telephone network is established by connecting to an exchange through a radio base station by a normal general call connection. A similar time service is being implemented. However, in the case of this service system, it is necessary to set up a communication line to a radio network controller for controlling a plurality of radio base stations and to a higher-level switching center. On the other hand, it is expected that requests for various information services will occur in the future, and if demand exceeds that of general telephone calls, it will affect the processing capacity of the radio network controller and switching center, and will reduce the number of wired lines. Will cause a shortage.

An object of the present invention is to provide a method for realizing various information services in mobile communication that are expected only in the future, with respect to information services possible only between a mobile station and a radio base station. .

(Means for Solving the Problems) The present invention provides a radio network controller, a plurality of radio base stations controlled by the radio network controller, and a radio base station whose communication channel is controlled by the radio base station. In a mobile communication system including a plurality of mobile stations communicating with a station, each of the radio base stations communicates between the incoming and outgoing control transceiver and the outgoing control transceiver and the plurality of mobile stations. A plurality of communication transceivers, a communication path switch for making a connection between the plurality of communication transceivers and a communication circuit group to the radio network controller, and a service information group stored therein. A service information providing unit connected to a road switch by a plurality of service information lines; and the communication path switch and the service information providing unit connected to the service information providing unit via a control bus line, respectively. A control unit for controlling the connection between the communication apparatus and the communication circuit group to the radio network controller and the connection between the plurality of communication transceivers and the plurality of service information lines, The control unit is further connected to the incoming call control transceiver and the outgoing control transceiver, and has a function of identifying an information service request code and a zone number included in a call signal from the mobile device. Connecting the plurality of communication transceivers and the plurality of service information lines via the communication path switch, so that the service information providing unit responds to an information service request call from the mobile device. This is an information service system in mobile communication, characterized in that information is provided from the Internet.

(Example) Hereinafter, an Example is described with reference to drawings.

FIG. 1 is an overall configuration diagram of a mobile communication system to which the present invention is applied. MSS is a mobile station, RZ1 to RZ3 are radio base stations installed for each radio zone, MCS is a radio network controller, and AMS is a switching center. , C-CH1 to 3 are station control channels, D-CH is a data channel, and S-CH1 to 3 are communication line groups assigned to each zone.

The mobile station MSS sends the information service request code INF-
When B and the zone number indicating the zone in which the current zone is located are received on a predetermined common communication control channel A-CH, the radio base stations RZ1 to RZ3 which have received the call signals respectively , And identifies the zone number in which the zone is located. For example, when the outgoing signal includes the serving zone number corresponding to the wireless base station RZ2, the processing of the calling signal is started in the wireless base station RZ2 that matches the serving zone number.
The other radio base stations RZ1 and RZ3 determine that the call signal is not a call signal for the own station, and discard the received call signal.

The zone number is automatically included in the outgoing call signal by a known method, for example, a multi-station simultaneous sequential transmission method, regardless of the zone in which the mobile station is located. The information service request code is generated by performing a predetermined operation in the mobile station MSS at the time of calling, and is included in the calling signal.

FIG. 2 shows a schematic configuration of the above-described radio base station RZ2,
With reference to this drawing, how the information service is implemented by the processing started in the radio base station RZ22 will be described.

The radio base station RZ2 has a radio transmission / reception device TRX-E, which comprises a reception control transceiver PTRX and a transmission control transceiver ATRX.
And call transceivers VTRX1-8. Radio base station RZ2
Also has a radio circuit base station controller BC-E, which comprises a control unit CONT, a speech path switch unit SW, and a service information providing unit.
Including SINF. The communication path switching unit SW and the service information providing unit SINF are connected by information service lines INF-CH1 to INF-CH3, and the communication path switching unit SW and the control unit CONT and the control unit CONT and the service information providing unit SINF are connected. They are connected by control bus lines BUS1 and BUS2, respectively. The communication path switch unit SW and the communication transceivers VTRX1-8 are connected by communication lines V-CH1-8. The same applies to other wireless base stations.

The control unit CONT in the radio circuit base station controller BC-E converts the call signal received through the incoming call control transceiver PTRX into the mobile station MSS located in its own zone by identifying the zone number in the visited zone.
When the information service request is recognized from -D, the information service request code included in the call signal is identified to recognize that the provision of the information service is requested instead of the general call. Next, the control unit CONT selects a vacant line of the communication lines V-CH1 to V-CH8.

Assuming that there is a line corresponding to the call transceiver VTRX6 as an idle call line, the control unit CONT establishes a wireless line between the mobile station MSS-D and the call transceiver VTRX6 by the call connection control function. The control unit CONT further controls the communication path switch unit SW through the control bus line BUS1 by the communication path selection connection control function, and connects the communication line V-CH6 and the information service line INF-CH2 as a communication path for information service. At the same time, the service information providing unit SINF is controlled to output the service information INF-B from the service information group of the service information providing unit SINF. The service information INF-B is transmitted from the antenna to the mobile station MSS-D through the communication transceiver VTRX6.

The above operation is the same when the mobile station MSS-C requests service information. In addition, mobile station MSS-A or M
The case of performing connection control for a call to SS-B is the same as in the related art, and a description thereof will be omitted.

(Effect of the Invention) As described above, for information that can be serviced in the radio base station, the station control channel C-CH for the radio network controller MCS and the communication line group S-CH for the exchange AMS are used. Instead, a specific information service can be performed for the subscriber of the mobile station.
