The present invention relates to a Calling Identification Display or Calling Identity Delivery (CID), wherein a Global Positioning System (GPS) chipset in which a positioning gateway is mounted on a wireless terminal based on a low power wireless communication technology. Tracking the location of the wireless terminal through the GPS-based wireless positioning technology using the mobile communication technology or the wireless network-based wireless positioning technology using the mobile communication base station, extracting the numerical location information of the wireless terminal, and transmitting it to the location-based calling service provider, After the location-based originating service provider generates location-based value information from the numerical location information of the originating terminal transmitted from the positioning gateway, the originating terminal calls the called terminal and is located at the time when the caller indication service is started. Recipients based value information In the mobile communication system, or CID information that is processed into a form applicable to the destination terminal, and transmitted to the destination terminal via the mobile communication system to a method for providing an attachment location of the sender process.

Caller ID service is provided based on Digital Switch and Common Channel Signaling No. 7 (Common Channel Signaling # 7). It appeared as one of the additional services of ISDN (Integrated Services Digital Network) in the 1970s. The caller ID service is a telephone call method that modifies the caller-oriented current phone call practice so that the caller and the receiver are equally related to each other.The caller selects the called party when the caller makes a call. It allows you to check who you are and choose whether to call you.

The caller ID service outputs the calling party's telephone number to the called party's terminal before the first ring and the second ringing in the caller's call connection process. In this case, the caller outputs the caller's name so that the called party can check who the caller is before answering the call.

In addition, the caller ID service can identify who is the caller who attempted to connect the call even when the called party is busy or absent, and by using the calling party number displayed on the called party's terminal as a callback number, an additional phone number Caller ID can be called immediately without re-entry, and the caller ID prevention service prevents the sender's own information from being displayed on the receiver terminal screen by the caller's request, and an anonymous caller who is not displayed on the receiver terminal by the receiver's request. There are a variety of additional features, such as anonymous call rejection services that allow you to selectively reject your call.

Meanwhile, a method of determining the location of a wireless terminal using wireless or mobile communication includes a GPS-based wireless positioning method in which a GPS chipset is embedded in the terminal, and a communication network for tracking the location of the terminal using a pilot signal used in a communication network. Based wireless positioning method, each of which will be described below.

GPS-based wireless positioning technology is a location tracking technology designed to acquire 3D location information of a wireless terminal regardless of time by analyzing satellite signals using 24 satellites. The elimination of intentional error, which has recently been included in GPS hypocrisy, improves the accuracy and practicability of GPS-based radio positioning, redesigning antennas, mitigating multipath using multi-correlator, and combining pseudo-satellite or communication networks. Due to the improvement of the DOP (Dilution Of Precision) in the city center.

Currently, GPS-based wireless positioning methods are largely divided into two types. First, a wireless device in which GPS is installed by embedding a low power GPS chipset in a wireless terminal or attaching a GPS module to a personal digital assistant (PDA). In order to eliminate the long warm-up time of GPS from 3 minutes to 10 minutes, the second base station transmits the satellite orbit information to the wireless terminal device from the base station Transceiver Subsystem (BTS). By transmitting the pseudorange data from the satellite to the base station, the base station can find the position of the wireless terminal in a short time.

* Network-based wireless positioning technology is a location tracking technology designed to obtain accurate two-dimensional location information of a wireless terminal by knowing the exact location and measuring the distance of the wireless terminal from a fixed base station. In the method for measuring the distance between the base station and the wireless terminal, the signal propagation time is calculated through a correlator and a delay lock loop (DLL), and in the case of time division multiple access, The distance between the wireless terminal and the base station can be measured. In the case of Code Division Multiple Access (CDMA), the PN (Pseudo random Noise) code set for each base station is signal-processed. You can measure the distance. If three or more base stations calculate the distance between the wireless terminal and each base station, it is possible to interpret two-dimensional position information for the wireless terminal by triangulation.

The distance between the wireless terminal and the base station can be determined by using the Angle of Arrival (AOA) method or the correlation between the radio wave arrival time. Time of Arrival (TOA) when the terminal sends a signal to the base station (Backward Link), Time Difference OF Arrival (TDOA) when the base station sends a signal to the wireless terminal (Forward Link), or Enhanced Observed Time Difference (EOTD) Method, etc.

An object of the present invention to solve the above problems is to provide a location-based caller indication service, based on a low-power wireless communication technology to locate a GPS (Global Positioning System) chipset equipped with a positioning gateway (Location Gateway) in a wireless terminal The location of the wireless terminal is tracked through the GPS-based wireless positioning technology or the wireless network-based wireless positioning technology using the mobile communication base station, and the numerical location information of the wireless terminal is extracted and transmitted to the location-based originating service provider. After the originating originating service provider generates the location-based value information from the numerical location information of the originating terminal transmitted from the positioning gateway, the originating terminal calls the called terminal and starts location-based service at the time when the caller indication service is started. Recipient side of value information By transmitting the same communication system, or processed into a form applicable to the destination terminal, and attached to the processing of the sender is located in CID information, the information transmitted to the destination terminal via the mobile communication system, a location-based caller ID to provide.

The present invention relates to a location-based caller ID service that attaches caller location information obtained through a wireless location technology to a CID. The present invention relates to the above-described wireless location technology and to positioning through all kinds of wireless location technologies available in a mobile communication system. The gateway extracts the numerical location information of the wireless terminal and transmits it to the location-based originating service provider.The location-based originating service provider analyzes the numerical location information of the wireless terminal transmitted from the positioning gateway and the request of the location-based originating service requester. Generating location-based value information, and analyzing the system performance of the receiver-side mobile communication system and the destination terminal by using the location-based value information at the time when the calling terminal makes a call to the called terminal and the location-based caller ID service is started. To the called terminal After processing to be output sender position information, the CID information to be transmitted to the destination terminal, and the like and sending by attaching the sender's location.

According to the present invention, the numerical information of the calling terminal obtained through the wireless positioning in the positioning gateway is called the calling terminal location information, and is generated by combining the request of the location-based calling service requester and the calling terminal location information in the location-based calling service provider. One piece of information is called location-based value information, and location information processed in the form that can be output to the destination terminal by analyzing the system performance of the called party's mobile communication system and the destination terminal at the time when the location-based origination service is started is called the caller location information. .

Hereinafter, the features of the present invention will be described in detail with reference to the accompanying drawings. However, the following drawings and descriptions are for representative methods among various methods for properly describing the present invention, and the present invention is not limited only to the following drawings and descriptions.

Although an embodiment of the present invention deals with a GPS method and a communication network positioning method for a wireless positioning method, a wireless terminal connects to a wired Internet network through a short range wireless communication such as Bluetooth or Wi-Fi. In this case, the location of the wireless terminal may be tracked through the access point of the short range wireless communication, and the handset of the wireless terminal may be used without using the wireless positioning method using a pilot signal even when using the communication network type positioning method. The approximate location for the originating terminal may be tracked based on the terminal information basically stored in the base station to handle the off. That is, the radio positioning technology used in the present invention is not limited to only a specific field.

FIG. 1 is a simplified diagram of a system for generating and processing location information, location-based value information, and caller location information of a calling terminal through GPS-based wireless positioning or a network-based wireless positioning. It is a block diagram.

The method of tracking the location of the calling terminal 135 or obtaining location information may be based on a GPS-based wireless positioning method, or by measuring a distance between the base station and the calling terminal 135 and using a triangulation method to locate the calling terminal 135. There is a communication network wireless positioning method for obtaining information, GPS-based wireless positioning method is to extract the three-dimensional location information of the calling terminal 135 using the GPS chipset mounted on the calling terminal 135, communication radio positioning The method does not need to be equipped with a special device in the terminal, but in order to obtain relatively accurate location information, it should be able to check the distance between the originating terminal 135 in three or more base stations.

The positioning gateway 115 is a system for controlling and managing location information of a mobile communication user. The positioning gateway 115 provides a location-based origination service using numerical location information and base station information of a wireless terminal obtained by a GPS method or a communication method. The role of providing a wired / wireless internet interface delivered to the provider 100 is described, and the role of the representative positioning gateway 115 will be described below.

The first role of the positioning gateway 115 is to process numerical information such as longitude and latitude by processing location information from the wireless terminal, and perform coordinate transformation and the like, depending on the type of service. To extract and provide the location of. For example, the earth ellipsoid coordinate system used in the GPS radio positioning method is different from the coordinate system used by the location-based calling service provider 100 serving the caller location information, and is different from the coordinate system used in the network-based radio positioning method. . Accordingly, the positioning gateway 115 must coordinate transform the numerical position information of the wireless terminal obtained through each wireless positioning scheme into a standardized form. In the above process, it may be instructed by using a short message service (SMS) or a WAP push function to forcibly inform the base station of the location of the wireless terminal. In the case of the CDMA scheme, information exchange for position calculation between the base station and the wireless terminal uses the IS-801 protocol.

The second role of the positioning gateway 115 is to authorize the location-based service provider 100, etc. requesting the location information for the wireless terminal, and encrypt the location information sent to the authenticated service provider 100. )do. In the present invention, the location gateway 115 encrypts the location information of the originating terminal 135 transmitted to the location-based originating service provider 100, thereby preventing the sender's personal information from leaking to the outside through an inappropriate method. In this process, the positioning gateway 115 uses a wireless transport layer security (WTLS) or end-to-end (E2E) security technology as well as an encryption algorithm such as a public key infrastructure (PKI).

The third role of the positioning gateway 115 is to register, manage, and maintain a wireless terminal to which wireless positioning is applied and a location-based service provider 100 such as the location-based originating service provider 100. Although the location-based originating service provider 100 is basically registered with the positioning gateway 115 in the present invention, the wireless terminal to which the wireless positioning is applied must be registered through the procedure required by the positioning gateway 115.

The location-based originating service provider 100 serves to generate location-based value information and caller location information transmitted to the called terminal 140 from the location information of the originating terminal 135 transmitted from the positioning gateway 115. Equipped with a Database Management System (DBMS) 110 in which D / Bs that store various location-based reference information for generating location-based value information from the location information of the calling terminal 135 are linked. Caller location information capable of generating and processing location-based value information and caller location information through the location-based reference information extracted from the DBMS 110 and the location information of the calling terminal 135 transmitted from the positioning gateway 115. The processing part 105 is mounted.

The DBMS 110 of the location-based origination service provider 100 includes a geographic information system (GIS) D / B and a digital map D that can express detailed locations of the city center and each province, including location-based origination service user D / B. / B, and all kinds of locations necessary for extracting location-based value information and caller location information from the location information of the calling terminal 135, such as system information D / B of the receiving terminal 140 provided with the location-based calling service. D / B that stores the base reference information and the like is linked, and the location-based reference information extracted from the DBMS 110 depends on the service request of the location-based originating service user and the characteristics of the called party. For example, location-based value information or caller location information may include “working at a company” or “consulting with a customer” rather than numerical location information “36.5 latitude Tokyo 128” or simple location information “Nonhyeon-dong, Gangnam-gu, Seoul”. The base value information is mounted, and the DBMS 110 stores the location based reference information necessary to generate such location based value information.

The caller location information processing unit 105 combines numerical location information transmitted from the positioning gateway 115 with various types of location based reference information stored in the DBMS 110 to generate location based value information. The type of location-based value information depends on the service request of the location-based originating service user and the performance of the receiver terminal 140 system. For example, when the data transmission speed of the called party's mobile communication system is low, the text-based caller location information is serviced, and the data transmission speed of the called party's mobile communication system 130 and the processing power of the called terminal 140 are improved. The sender location information is processed in the form of image data or a VM (Virtual Machine) of the destination terminal 140. The sender location information is processed in the form of an image. The location of the caller may be displayed on a digital map stored in B, and may be transmitted. When processed into a form that can be driven by a VM of the called terminal 140, a form of wireless Internet-based multimedia content such as a flash animation on the wired Internet may be transmitted. Sender location information is processed and transmitted.

2 is a simple flowchart of a process of the location gateway 115 obtaining numerical location information of the originating terminal 135.

As described above, the radio positioning method used in the present embodiment uses both a GPS based radio positioning method and a communication network based radio positioning method. Therefore, when the power source of the calling terminal 135 is input and the calling terminal 135 is connected to the mobile communication system (200), the positioning gateway 115 is the home location register (HLR) / HLR of the calling party mobile communication system 120 It analyzes terminal information stored in the VLR (Visitor Location Register) or each base station, or information transmitted / received between the terminal and the mobile communication system to determine whether the GPS chipset is mounted in the calling terminal 135 (205). If the calling terminal 135 is equipped with a GPS chipset (210), the positioning gateway 115 switches the GPS-based wireless positioning method (215), on the contrary, if the calling terminal 135 is not equipped with a GPS chipset, positioning The gateway 115 is switched to a network based wireless positioning method.

When the GPS chipset is mounted on the calling terminal 135 to use the GPS-based wireless positioning method (210), the GPS chipset mounted on the calling terminal 135 is connected to the calling terminal 135 from the GPS satellite in the satellite orbit. After calculating the current position of the originating terminal 135 through the three-dimensional position information and the internal algorithm, and transmits it to the positioning gateway 115 (220). At this time, the GPS chipset mounted on the originating terminal 135 is driven based on low power technology, and the location information transmitted from the originating terminal 135 to the positioning gateway 115 is also in a range that does not put a load on the mobile communication system. Is optimized.

However, if the calling terminal 135 is not equipped with a GPS chipset (225), the positioning gateway 115 checks the base station information for the calling terminal 135 from the terminal information stored in each base station for handoff. Then, the base station measures the distance from the calling terminal 135 (230). At this time, in order to obtain the exact location of the calling terminal 135, at least three base stations should be able to check the calling terminal 135, but even under the conditions it can obtain the approximate location information of the calling terminal 135. (235). When the distance from the originating terminal 135 is obtained from each base station as described above, the positioning gateway 115 is based on the communication network using triangulation method from the fixed position information for each base station and the position information between the originating terminal 135, and the like. The location information of the calling terminal 135 is obtained through a wireless positioning method. At this time, the caller terminal 135 does not need to be equipped with a special device, and because the position of the caller terminal 135 is obtained through a pilot signal between the caller terminal 135 and the base station, the position of the caller terminal 135. No further data communication occurs between the originating terminal 135 and the base station for extraction.

When the location information of the calling terminal 135 is obtained as described above, the positioning gateway 115 converts the calling terminal 135 location information into a coordinate system used by the location-based calling service provider 100 (240). The converted source terminal 135 location information is immediately transmitted to the location-based source service provider 100 (245). After the caller terminal 135 is connected to the mobile communication, the process is repeated periodically in a low power state that does not seriously consume the power of the caller terminal 135 and does not put a load on the mobile communication system.

3 is based on the location information transmitted from the positioning gateway 115 by the caller location information processing unit 105 mounted in the location-based calling service provider 100 and the location-based reference information stored in the DBMS 110. Generate location-based value information, and process the caller location information optimized for the called party's mobile communication system and the called terminal 140 when the calling terminal 135 calls the called terminal 140 and the CID service is started. Is a simple flow diagram for the process of transmitting to the destination terminal 140.

When the power of the calling terminal 135 is input and the calling terminal 135 is connected with the mobile communication system 300, the location-based calling service provider 100 requests a request of the location-based calling service requester for the calling terminal 135. Analyze (305). In general, the location-based originating service requester is a user of the calling terminal 135, but in some cases, a third party other than the calling terminal 135 user may request the location-based calling service. For example, if a minor uses the calling terminal 135, the parent of the user may request a location-based calling service, and if the calling terminal 135 is for business use, the superior of the user is located. You can also request a base calling service.

Accordingly, the location-based originating service provider 100 analyzes a request of a user who can request a legitimate location-based originating service for the user of the originating terminal 135 or the originating terminal 135, and then the DBMS 110 requests the corresponding request from the DBMS 110. The location-based originating service provider 100 extracts location-based reference information capable of providing the requested service (310).

Then, when the location information on the originating terminal 135 is received from the positioning gateway 115 (315), the caller location information processing unit 105 mounted in the location-based originating service provider 100 is the positioning gateway 115 Combining the location information of the originating terminal 135 received from the location-based reference information extracted from the DBMS 110, etc. to generate location-based value information for the originating terminal 135 (320), the process is location-based The calling service repeats until the calling service is started or the calling terminal 135 ends the connection with the mobile communication system (325).

If the calling terminal 135 calls the called terminal 140 and the location-based calling service is started (330), the caller location information processing unit 105 is connected to the called party's mobile communication system and the called terminal 140. Run system performance analysis (335). In general, the called terminal 140 has various performances according to the manufacturer or model of the terminal, and the type of the location-based outgoing service that may be available may also vary according to the called party's mobile communication system.

Therefore, the location-based calling service provider 100 analyzes the performance of the called party's mobile communication system and the called terminal 140 when the calling terminal 135 calls the called terminal 140 and the location-based calling service is started. By performing the operation, the location-based value information may be processed into caller location information output to the called party (340).

When the performance analysis of the called party's mobile communication system and the called terminal 140 is completed, the caller location information processing unit 105 of the location-based originating service provider 100 receives the location-based value information generated through the above process. The called terminal 140 processes the caller location information that can be output for the purpose of the CID. Then, by including the sender location information processed in the state capable of output to the destination terminal 140 in the CID information transmitted to the destination terminal 140 (345), and transmits the caller location information to the destination terminal 140 (350). .

4 is a simple terminal example provided with a caller indication service including location based value information.

This figure is an exemplary diagram in which the caller's location-based value information is provided and received to a wireless terminal of a client applying for the caller ID service including the location-based value information, and the call is received from the client having the number 0xx-xxx-xxxx. When called, the called party's wireless terminal displays the location-based value information of the originating client.

In this figure, it can be seen that the simple location information of 'Nonhyeon-dong, Gangnam-gu, Seoul' and the originating indication of 'company-working', which is location-based value information of the originating client, are transmitted.

According to the present invention, by providing a caller indication service containing the location-based value information, by checking the caller indication that includes the caller's location-based information of the caller requesting to initiate the call to the wireless terminal of the called party to initiate the call; There is an advantage that can grasp the location and location information.

Parental clients also have the advantage of being able to more easily identify their location through incoming calls from their children.
