Description

Wireless calling system with local information

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio calling system, and more particularly, to a radio calling system for providing information to a pager user of a region where a base station is located.

The radio paging system consists of a paging terminal, a plurality of base stations and a pager. Here, the paging terminal receives a message transmitted by the wireless caller using a telephone or the like, and transmits a signal corresponding to the received message to a corresponding base station among a plurality of base stations. Among the base stations, the corresponding base station receives a signal corresponding to the message transmitted by the paging terminal and transmits it to the corresponding pager (or wireless pager). Therefore, the pager user can know the information transmitted by the radio caller through the pager.

The above pager has only a receiving function and no calling function. That is, the pager owned by each user is assigned only an individual number, and therefore, only the information corresponding to the number is taken from the data transmitted from the base station. Therefore, under current radio calling systems, pager users, unlike mobile phones, cannot know where they are currently located using only the pager.

The present invention has been made in an effort to provide a wireless paging system capable of providing region information for a pager user to know information about a region where a base station is located.

1 is a schematic diagram of a typical radio calling system.

In order to achieve the above object, a wireless paging system capable of providing local information according to the present invention includes a paging terminal that receives a message transmitted from a caller through a public circuit network, and receives a signal corresponding to the message transmitted from the paging terminal. A base station which transmits the call signal from the base station and the base station transmitting the call signal to the call receiver and provides the message to the call receiver in the form of predetermined data, and region information on the region where the base station included in the received call signal is located; It is preferred that the caller is configured with a pager that allows the callee to identify the area where the current call receiver is located.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of a wireless call system capable of providing local information according to the present invention will be described as follows.

1 is a schematic diagram of a typical radio calling system, comprising a general telephone 10, a public line network 20, a paging terminal 30, base stations 40, 42, ... and 44 and a pager 50 It consists of.

The caller transmits a message in the form of letters or numbers to the operator's paging terminal 30 via the telephone 10 shown in FIG. 1, and the paging terminal 30 is connected to the public line network (PSTN network) 20. A message transmitted from the ordinary telephone 10 is received, and the received message is transmitted to the paging transmitters 40, 42, ..., and 44 using a dedicated network according to a specific transmission protocol.

At this time, each of the base stations 40, 42, ..., and 44 receives a signal corresponding to the message transmitted from the paging terminal 30, and receives the received signal and the region information on the region where the base station itself is located. Are mixed, the mixed signal is decoded, and the decoded signal is transmitted to the pager 50 user as a call signal. Alternatively, the base station 40, 42, ... or 44 may transmit the area information to the pager 50 at predetermined time intervals regardless of the signal corresponding to the message even if a signal is not received from the paging terminal 30. .

Here, the base station 40, 42, ... or 44 may transmit the area information included in the call signal to the pager 50 in the form of text information or in the form of a predetermined code. That is, the local information may be sent in a form of data transmission, that is, in the form of text information on a data format or a protocol, or may be transmitted in the form of a code reserved in advance with the pager 50 to increase transmission efficiency per channel. How the base station includes the local information in the transmission protocol may vary depending on the protocol. For example, in the case of the Post Office Code for Standard Addressary Group (POCSAG) protocol, local information is included in an idle code word that does not contain actual data and the pager 50 is selected when the positioning function is selected. For example, it is possible to display the information after checking the information or to include the location information at a specific location previously reserved with the receiver during one cycle of the transmission protocol. In the case of the FLEX protocol, a variety of data addressing methods are available in addition to the above-described methods, thereby making it easier to implement such a function.

On the other hand, the pager 50 receives the call signal from the base station 40, 42, ... or 44 to provide a message to the call recipient, that is, the user of the pager 50, in the form of predetermined data, and to the received call signal. It provides the pager user with local information about the area where the included base station 40, 42, ... or 44 is located so that the called party can identify the area where the current called party is located. To this end, the pager 50 needs a separate function that can check the information of the code form in the decoder or the microcomputer.

Meanwhile, the pager 50 may provide the call receiver with local information included in the call signal transmitted from the base station at a predetermined time in response to the call receiver's request. That is, the user of the pager 50 may know when the predetermined area is reached by using an alarm function between movements. For example, when the user of the pager 50 is tired while moving on a bus and wants to sleep for a while, the user may select the alarm function and the local information providing function to automatically ring the pager 50 when the desired area is reached. Makes it easy for users to see if they are located in the area. Therefore, the pager user can enable a specific area reservation alarm function to prevent the user from falling asleep while passing the target point, and prepares a place where he will get off in advance.

In conclusion, when the base station is at a subway station or a bus stop, the user of the pager 50 using public transportation can receive information about the current location from the base station anytime, regardless of place or time.

As described above, the wireless paging system capable of providing local information according to the present invention may further expand the application range of the pager by allowing the currently commercially available pager user to easily recognize information on a specific area where the user is currently located. That is, the pager user can check a specific area name when visiting a specific place, for example, a subway station or a specific bus stop, which is unknown to the user, thereby avoiding the trouble of asking for help from other people.
