Description

Method for providing location information of called subscriber using data service

The present invention relates to a method for providing location information of a called subscriber, and more particularly, to a method for providing a caller with the current location information of a called subscriber in real time using a data burst message such as an SMS message, and a recording medium recording the same. It is about.

Currently, various additional services are provided to subscribers in mobile communication networks. Among them, a short message service (SMS), a caller ID service, and a location information service are provided.

Korean Unexamined Patent Publication No. 2003-0006091 discloses a method for providing location information of a calling subscriber. This is as follows.

When there is a call origination at the mobile station of the originating subscriber, the exchange receiving the call origination, i.e., the originating exchange, queries the home location registrar for the location of the called subscriber to determine the roaming location of the called subscriber. At this time, the calling side exchange 14 sends the calling party's calling number (CNI) information and the calling subscriber's Location Area ID (LAID) to the home location register.

Accordingly, the home location register means that the called number (CNI) information and the number of the called subscriber is activated as a location information service subscriber after confirming that the called subscriber is activated as a location information service (ICS) subscriber. The location information service request message including the service ID (ICS = 126) is transmitted to the call control system. Subsequently, the call control system confirms whether the called party's location information service is registered, and includes the location information corresponding to the calling party's location area ID (LAID) in the display text and includes a response message including an action code. Send to the home location register.

The home location register receiving the response message to the location information service request message allocates a Routing Number (TLDN) to the destination exchange from the originating exchange to the destination exchange so that the incoming subscriber can be made. The display text is included in the request message and transmitted to the exchange in which the called party is located.

Accordingly, the called side exchange assigns a routing number (TLDN) to the home location registrar, and sends the received routing number to the calling side exchange. The originating exchange then sets up an outgoing call with the called exchange based on the received routing number, thereby establishing a call between the originating exchange and the destination exchange 16.

As the call between the calling exchange and the called exchange is established, the called exchange transmits the display text (including the location information of the calling subscriber) provided by the home location register to the mobile station of the called subscriber. Send a signal At this time, the called party exchange also transmits calling party number information of the calling party. Accordingly, the mobile station of the called party is ringing and the calling party's telephone number and the calling party's location are displayed on a display device (not shown). Such a method of providing caller location information may provide the called party with the current location information of the calling party. However, the caller location information providing method can only provide the current location of the calling subscriber, and cannot provide the caller's current location information in real time.

Another service is the voice mailbox service. The voice mailbox service is a service that leaves a voice message of the calling subscriber when the called subscriber does not answer the call. However, the voice mailbox service can only leave a voice message informing the called subscriber of urgent business, and the calling subscriber will continue to call the called subscriber if the called subscriber is in a condition that he cannot answer the call. In this case, if the calling subscriber can know the current location of the called subscriber, this inconvenience can be solved.

Accordingly, an object of the present invention is to provide a method for providing a current location of a called subscriber to a calling subscriber in real time using a data burst message and a recording medium recording the same.

In order to achieve the above object, the present invention provides a method for providing location information of a called party to a calling party, comprising: receiving a location information of a called party from a home location register by a call setup request of a calling party mobile station; ; A second step of generating a message in a form that the calling subscriber can recognize the location of the current called subscriber by using the received location information of the called subscriber; A third step of designating a message type of the generated message and transmitting the generated message to a data burst message server; And the data burst message server converts the message indicating the current location of the received called subscriber into a data burst message, and transmits the converted data burst message to the mobile subscriber station of the calling subscriber by including an identifier indicating the message type. And a fourth step for the mobile station receiving the data burst message to buffer and display the received message in real time.

Preferably, in the third step, information indicating the message type and a manner for notifying the reception of the message by the mobile station is transmitted to the data burst message server together with the generated message.

Preferably, in the first step, the home location register delivers the location information of the called subscriber to the additional service server when the called and calling subscriber subscribes to the service.

Preferably, the data burst message server transmits the message type and the reception notification method indication information of the message in an unassigned teleservice identifier of the data burst message.

In addition, the present invention comprises the steps of: receiving, at a computer, location information of a called subscriber from a home location register by a call setup request of a calling subscriber mobile station to provide location information of the called subscriber to a calling subscriber; Generating a message in a form in which a calling party can recognize a location of a current called party by using the received location information of the called party; Designating a message type of the generated message and transmitting the generated message to a data burst message server; And the data burst message server converts a message indicating the current location of the received called subscriber into a data burst message, and transmits the converted data burst message to a mobile station of the calling subscriber by including an identifier indicating the message type. A computer readable recording medium having recorded thereon a program for executing a step of receiving a data burst message by a mobile station to buffer and display the received message in real time.

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

1 is a block diagram of a mobile communication network to which the present invention is applied.

The originating and terminating mobile stations (MS) 11, 19 are preferably portable telephones, which communicate wirelessly with the base stations (BS) 12, 18. The base station controller (BSC) 13, 17 controls a plurality of base stations (BS), and the originating and terminating mobile switching center (MSC) (14, 16) constitutes the subscriber's call path and performs connection with other communication networks do. The home location register (HLR) 15 provides all the permanent information of the mobile station user (e.g., terminal information (NIM, ESN), subscriber information necessary for connecting incoming calls to the mobile station (MS) or providing other mobile communication services). , Additional service information, etc.). The supplementary service server (TIIS) 20 receives the current location information of the called subscriber from the home location register 15 and changes the location information to a place name known to the subscriber, and sends a message (for example, 011-9900-0010). 'S current location is Yeouido.) And delivers it to the Data Burst Message (DBM) server 21. At this time, the information indicating the display form of the message indicating the location information is transmitted to the data burst message server 21. Optionally, information indicating a format for notifying reception of a message at the mobile station may also be transmitted from the supplementary service server to the DBM server.

The data burst message server 21 may be an SMS message center. When the message indicating the current location information of the called subscriber is transferred from the additional service server 20 by specifying the display type of the message, the data burst message server 21 The message indicating the current location information of the called subscriber is converted into a data burst message, and the message type identifier and the message receiving notification method indication information are inserted and transmitted to the mobile station of the calling subscriber through the calling exchange. The message type identifier and the message reception notification method indication information may be used to identify and process data included in the message by the mobile station that has received the data burst message. The teleservice identifier of the CHARi field of the data burst message may be used. ID) value. That is, by transmitting the current location information of the called party using a predetermined unassigned teleservice identifier value, the mobile station can process it separately from the general SMS messages.

2 is a flowchart illustrating a method of providing receiver subscriber location information according to the present invention.

First, the mobile station MS of the calling subscriber sends a message requesting call establishment to the calling MSC through the base station and the base station controller. At this time, information of the calling subscriber mobile station and the telephone number of the called subscriber are transmitted.

Upon receiving the call establishment request, the calling party mobile exchange inquires the current location of the called party mobile station to the home location register (HLR) which stores the information of the called party mobile station through a normal procedure. Such a process is a conventional process, and a detailed description thereof will be omitted.

The home location register inquired about the current location of the called party checks whether the calling party and the called party subscribe to the location information providing service. Of course, the confirmation of whether to subscribe to the service may be optional in the present invention, but it is preferable to provide the service only to the service subscriber for the protection of personal information. If both the called party and the calling party confirm that the subscriber subscribes to the service, the home location register sends the current location information of the called party (which may be a base station identifier) to the calling mobile switching center (MSC) and the additional service server (TIIS). At the same time.

When the calling party mobile switch (MSC) receives the location information of the called party from the home location register, it requests a call setup to the called party mobile exchange where the called party is located according to a normal call processing procedure. The call processing procedure is a conventional well-known technique, and a detailed description thereof will be omitted in the following description.

On the other hand, when the additional service server (TIIS) receives the calling subscriber information, the called subscriber information and the current location information from the home location register, the TIIS generates a message for notifying the calling subscriber of the location of the called subscriber. That is, since the location information provided by the home location register is information for routing to the base station where the called subscriber mobile station is currently located, and is not a general name known to the subscriber, it is changed to a name known to the general subscribers. -9900-0010's current location is Yeouido. " The additional service server transmits the generated message to the DBM server by including a message type for distinguishing from a general SMS message and information indicating a method of notifying a subscriber. That is, the supplementary service server includes a message type to instruct the generated message to be displayed in real time in a mobile station, distinguished from a general SMS message. In addition, the additional service server includes information indicating a format (for example, a buzzer or a flashing light) for notifying the subscriber that the message has been received. Of course, the message reception notification method indication information is not necessarily included as an optional requirement. At this time, the telephone number to receive the message is the telephone number of the calling subscriber.

When the DBM server receives the message, the message type, the message receiving notification method indication information and the telephone number to be received (that is, the calling party's telephone number) from the supplementary service server, the DBM server generates a data burst message using the transmitted information and transmits the message to the MS. do. The data burst message inserts the calling party's telephone number into the received telephone number field, and includes a message indicating the location information of the called party, a message type identifier, and message receiving notification method indication information. The message type identifier and the message reception notification method indication information use an unassigned teleservice identifier field as described above. Of course, it will be apparent to those skilled in the art that the message type identifier and the message reception notification method indication information may be transmitted in a form other than a teleservice identifier.

When the originating subscriber mobile station receives the data burst message, it recovers the received data burst message to confirm the message type. If the result of the verification is a normal SMS message, the mobile station stores the message in a nonvolatile memory in the same manner as normal SMS message processing, and then notifies the subscriber of the message reception. On the other hand, if the check result is a message that requires real time display instead of a general SMS message, the mobile station stores the received message in volatile memory and immediately displays it on the display unit. That is, when the received message is a message requiring real time display, the received message is stored in a volatile memory used as a buffering function in the mobile station, and thus the received message is immediately displayed on the display. The mobile station also notifies the subscriber that the message has been received according to the message reception notification method indication information included in the mesh through message interpretation.

On the other hand, when a call is established with the mobile station of the called party by the call processing of the calling party mobile switch, the calling party mobile station stops displaying the message displayed on the display. Of course, the display of the message is stopped even when the calling subscriber stops the call establishment request without a call being established between the calling party mobile station and the called party's mobile station.

According to the present invention as described above, the current location of the called party can be notified to the calling party in real time, the calling party can know the current location of the called party even if the called party does not answer the phone. Accordingly, the calling subscriber can predict whether or not the called subscriber is moving to an appointment place.
