How to notify if you are entering a discounted area on your mobile phone {Method for informing the fact of being in the discounting zone in mobile phone}

The present invention relates to a method of determining whether a mobile phone is currently in a discounted area by using base station identification information in a mobile communication network and then notifying the user.

Conventional techniques for determining the location of a mobile phone include a global positioning system (GPS) method and a base station-based method. The GPS method is a GPS receiver that measures the exact time and distance from three or more satellites and accurately calculates the current position by triangulation of three different distances. The base station-based method uses three base stations and two of them. It is to determine the location of the mobile phone by measuring the relative difference of the radio wave arrival time from the base station to the terminal.

However, in order to apply the above technology, a GPS system composed of GPS satellites, a control station, a GPS receiver, or the like must be constructed, or a separate system for transmitting location information measured using three base stations to a mobile phone must be constructed. There was a problem of having to spend additional costs in order to receive the service.

In order to solve this problem, there is a prior art for identifying a location of a mobile phone and establishing a connection with a regional discount notification service without establishing the additional system.

The present invention relates to a method for notifying a discount rate region in a mobile communication system, comprising: setting a rate discount region notification service region by receiving region information to be discounted from a terminal of a charge discount region notification service subscriber; Querying the base station list from the base station DB to select the corresponding base station; accessing the subscriber DB according to the selection; updating the corresponding subscriber DB; collecting the selected base station information and the updated subscriber information; Generating a message and transmitting the message to the terminal; and receiving the message, comparing the base station information message provided from the base station, and outputting a message of a charge discount area in the same case.

Here, although the prior art uses a short message service to transmit discounted area information to the terminal, this can be seen as a cumbersome system configuration because it can be solved by using forward data transmission in the existing mobile communication network. If you need to receive a short message to know whether or not in a discount area in real time, it is a great burden for the entire system and a mobile terminal.

The present invention has been made in view of the above, and when receiving a base station identification information in the mobile communication network and compares with the base station information previously stored in the mobile phone, if there is a matching base station, that is, the current mobile phone is located in the discount zone In this case, an object of the present invention is to provide a method of alerting the user with a voice or displaying an icon on a mobile phone screen.

According to an aspect of the present invention, a first step of receiving base station identification information from a base station and a second step of reading prestored discount area base station information and comparing the received base station identification information with the result of the comparison And if there is a base station, a third step of notifying the user that the user is located in the discount area. In this case, the discounted area base station information is configured to include a base station ID (PN) and PN sequence, and downloading the database of the discounted area base station information in advance and storing it in a mobile phone memory. It may be further provided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a functional block diagram of a mobile phone for implementing the inventors whether the entry in the discount area.

The controller 108 performs wireless communication or data processing of the entire cellular phone and controls respective parts of the cellular phone to be described later. In the present invention, the base station ID and PN sequence are extracted from base station identification information received from neighboring base stations, and compared with the base station ID and PN sequence among the discount area base station information previously stored in the memory unit 106. / Search, and when there is one or more matching base stations, the voice data for the discount area entry alarm stored in advance is read from the memory unit 106 and transmitted to the voice processing unit 116.

The display unit 102 may be generally configured as a liquid crystal display (LCD). The display unit 102 receives data to be displayed under the control of the controller 108 and displays various messages such as an operation state of a wireless cellular phone, dialed data, and the like. In the present invention, an interface for downloading the discount area base station information previously built into the database and an icon indicating that the discount area has been entered are displayed on the top of the screen when it is determined as the discount area by the present invention.

The memory unit 106 has an area for storing control program codes, various data, and data stored by a user required for the operation of the controller 108. In particular, an area for storing voice data for an alarm and a discount area base station information, that is, an area configured to download and store a database configured to include a base station ID and a Pien sequence are provided.

Other factors that make up the mobile phone are as follows.

The key input unit 104 includes various keys including a digit / character key, a call key, an end key, and the like, and generates and provides a key signal corresponding to a key pressed by the user to the controller 108.

The voice processor 116 converts the voice data received by the receiver 110 into an analog electric voice signal under the control of the controller 108 and outputs the voice data to the speaker SPK. Then, the speaker SPK converts the electrical voice signal into an audible sound and outputs the audible sound. The microphone converts the voice into an electrical voice signal and provides the voice to the voice processor 116.

With such a structure, a mobile phone for implementing the present invention may be a cordless phone, a cellular phone, a PCS phone, an IMT2000, or the like.

2 is a network diagram for implementing a method of notifying whether or not to enter the discount area according to the present invention.

In general, a mobile communication network may include a mobile switching center (MSC), a base station controller (BSC), a base station transformer subsystem (BTS), and a mobile station (MS). One Public Land Mobile Network (PLMN) has a number of MSCs, each of which also has a number of BSCs, and these BSCs control several BTSs.

In this case, the MSC performs control to access the BSC, the Public Switch Telephone Network (PSTN), and the Public Mobile Communication Network (PLMN), which is not the core of the present invention. It explains in detail.

The BSC performs radio link, radio link control, and handoff functions, and the BTS, together with the MS, configures a radio channel and manages radio resources. In general, BTS refers to a base station, and MS refers to a mobile phone terminal.

Let's look at the path of information movement on the network.

Receiving a unique base station ID from the BSC 207, the BTSs 203 and 205 transmit it to the MS 201 in the jurisdiction (Cell) along with a unique PN sequence for each BTS.

Here, since the field of the base station ID is composed of 16 bits, it may have 2 ^ 16 base station IDs. However, since the number of base station IDs is sufficient, base station IDs may be assigned to all BTSs in Korea, but in principle, base station IDs are allocated for BSCs, and therefore, PN Sequense is required to obtain a unique BTS.

Now, assume that a discount zone 209 is included in a cell managed by a BTS, and the MS 201 enters the discount zone. At this time, if the MS 201 belongs to only one cell, the base station identification information will be received only from the BTS 203 or 205 that manages the cell, and the MS 201 is located in the handover area. In this case, the information (base station identification) will be received from both BTSs 203 and 205.

If the received information is compared with the discounted area base station information previously stored in the memory, and there is a matching base station (there may be two or more in the handover area), this means that the discounted area is included in such a base station. While notifying a voice that a discount area has been reached, the mobile phone screen keeps displaying an icon light 211 indicating that the discount area is at the top of the mobile phone screen while the discount area is reached.

Figure 3 is a flow chart for implementing a method of notifying whether the present inventors enter the discount area.

First, the discounted area base station information including the base station ID and the PEN sequence is downloaded from the previously built database and stored in the memory of the mobile phone (S301). At this time, when the database is updated, it would be desirable to provide a service that the service provider automatically downloads using the Broadcase Service of the wireless Internet so that the user of the location information service according to the present invention can be easily updated.

In the idle state, the cellular phone always receives base station identification information from the base station through the forward control channel (S303), which means a base station ID and a PN sequence.

The mobile phone compares / searches the received base station identification information and the previously stored base station information with each other to calculate a matching base station (S305). At this time, the mobile phone is a handover in which two or more base station cells overlap. ) If it is located in the area, it will receive each identification information from the corresponding base stations, so there may be several matching base stations.

In this case, the user is notified once by voice that the user has entered the discounted area, and an icon indicating that the user is currently in the discounted area is displayed on the top of the mobile phone screen while remaining in the discounted area (S309).

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

As described above, according to the present invention, when the base station identification information is received from the mobile communication network and compared with the discount area base station information previously stored in the mobile phone, if there is a matching base station, that is, the current mobile phone is located in the discount area. It provides a method of alerting the user by voice or displaying an icon on a mobile phone screen. As a result, it is possible to roughly grasp the current location without establishing a separate location calculation system such as GPS or three base station systems, and it is possible to check in real time whether the current state of entry into the discount area using this.
