The present invention relates to a call processing method using multiple or selective paging procedures using originating location information, and to a computer readable recording medium recording a program for realizing the method. A call processing method for providing a new application service according to multiple or selective paging procedures using information (cell / sector or latitude / longitude / altitude) and a computer-readable recording medium recording a program for realizing the method. It is about.

In this case, multi-paging modifies and supplements a paging method for location area indication (LAI) and paging area indication (PAI) used in a conventional mobile communication to search for locations of terminals joined to a specific group to search for a specific paging area (paging). Paging simultaneously, and selective paging refers to paging only to a particular subscriber. By using such multiple paging or selective paging, a call can be requested to any called party or a specific subscriber belonging to a specific group, thereby providing various application services.

1A and 1B are flowcharts of a call processing procedure for a call in a conventional mobile communication system, and show a normal call processing procedure between mobile subscribers.

When the mobile terminal 11 requests origination from the base station / base international controller 12, the base station / base international controller 12 requests the mobile switch 13 to set up a call. Subsequently, the mobile exchange 13 requested to set up the call proceeds to the base station / base international controller 12 and requests channel allocation, and requests the called terminal location to the subscriber home location register 15.

Subscriber home location register 15 then requests routing information to subscriber visit location register 16, and subscriber visit location register 16 requests routing information to mobile switch 17. Accordingly, the mobile switch 17, which has requested routing information, notifies the subscriber visit location register 16 of the routing information, and the subscriber visit location register 16 notifies the subscriber home location register 15 of the routing information.

Then, the subscriber home location register 15 notifies the mobile station 13 of the destination terminal location, and the base station / base international controller 12 also notifies that the channel assignment is completed, and then sends the ISUP (ISDN) to the mobile exchange 17. USER PART) Sending the first address message (IAM), mobile exchange 17 requests paging to base station controller / base station 18.

Subsequently, after performing paging between the base station controller / base station 18 and the mobile terminal 19, the base station controller / base station 18 sends a response to the paging to the mobile switch 17.

Accordingly, when the mobile switch 17 sets up a call to the base station controller / base station 18, the base station controller / base station 18 sends a response to the call setup request to the mobile switch 17, and the mobile switch 17 Upon requesting the channel assignment, the base station controller / base station 18 simultaneously informs the mobile switch 17 and the mobile terminal 19 that channel assignment has been completed.

The mobile terminal 19 then responds to the base station controller / base station 18, the base station controller / base station 18 responds to the mobile exchange 17, and the terminating mobile terminal 17 responds to the originating mobile exchange 13 When the ISUP (ISDN USER PART) address completion message (ACM) is transmitted, the base station / base station controller 12 notifies the terminal.

On the other hand, if the mobile terminal 19 requests call connection to the base station controller / base station 18, the base station controller / base station 18 connects the call and then sends a response to the request to the mobile terminal 19 again. When the controller / base station 18 requests a call connection to the mobile switch 17, the mobile switch 17 sends a response to the request back to the base station controller / base station 18 after connecting the call.

At this time, when the incoming mobile switch 17 transmits an ISUP (ISDN USER PART) head address message (IAM) to the mobile switch 13, the mobile switch 13 establishes a call connection to the base station / base international controller 12. In response, the base station / base international controller 12 connects the call to the mobile terminal 11. Then, the base station / base international controller 12 responds to the connection to the mobile exchange 13, the call is connected.

As illustrated in FIGS. 1A and 1B, a paging procedure (general page) for calling a subscriber in a conventional mobile communication system refers to grouping several base stations into one paging area (LAI, PAI).

Meanwhile, a call taxi service using a GPS (Global positioning system) satellite is commercially available. This means that a person who wants to provide a call taxi service calls a call taxi control center and informs his / her location of the call taxi. It was supposed to inform.

However, this is a problem that each time you use a call taxi to call the control center to tell their location.

In a method for providing an application service by multiple or selective paging procedures using originating location information (cell / sector or latitude / longitude / altitude) according to the present invention, the location information of the caller may be provided in the current mobile communication. It should be implemented as an information cell / sector, but location information requiring accuracy should be able to be implemented not only with cell / sector information but also with latitude, longitude, and altitude information.

When the caller requests a call for the location information service, the MSC determines that the call is for a location service (LCS) and requests the location service server (LSS) for the location service. According to the requested service, the subscriber selects the subscriber located in the area closest to the calling party by using multiple or selective paging procedure to connect the call. Here, in order to connect a call, a call should be provided to subscribers closest to the caller by multiple or selective paging procedures to subscribers registered in a specific group or a specific service using the caller's location information.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is an exemplary configuration diagram of a wireless communication system to which the present invention is applied.

As shown in FIG. 2, the wireless communication system adds a location information service server (LSS) 11 that controls a location information service while using an existing mobile communication network.

The mobile switch / subscriber visited location register 13 should have a function of discriminating a location information service call, and implement a subscriber-specific cell / sector information table in a subscriber visited location register (VLR) controlled by the mobile switch.

Here, the location information service server 11 may be directly installed in the mobile communication network if the mobile communication provider wants to provide its own additional service, or may be installed in the company providing the location information service if the operator wants to provide the line. . If the operator wants to provide the circuit, the mobile switch / subscriber visited location register 13 only needs to provide a function for routing a call when the caller requests location information service.

The location information service server 11 searches for a group or a specific subscriber subscribed to the location information service according to the type of location information service of the calling subscriber, and notifies the mobile switching center / subscriber visited location register 13 of the result. According to the result of the search, the mobile exchange finds the subscriber in the same location as the caller's cell / sector among the subscriber location information in the location information table of the subscriber visited location registrar.

According to the result of finding the subscriber, the mobile switching / subscriber visited location register (13) can page the location service subscription group or a specific subscriber according to the multi-paging or selective paging procedure, and in case of multi-paging, the mobile station / subscriber visited location register 13 Provide location information service by connecting calls.

Here, the location information service server 11 manages the location information service subscriber profile and the subscriber by the representative number, searches for the subscriber, notifies the mobile switcher of the result, and provides the mobile subscriber's location information (cell / sector or Latitude / longitude / altitude).

In addition, in the mobile switching / subscriber visited location register 13, the mobile exchange can translate a call for the location information service, request the call routing or location information service to the location information service server 11, and the subscriber visited location register. The mobile subscriber may implement the location information (cell / sector or latitude / longitude / altitude) of the mobile subscriber, and perform subscriber search and notification required by the location information service server 11.

3 is a conceptual diagram of a call processing scheme by multiple or selective paging procedures according to the present invention.

As shown in FIG. 3, the present invention relates to a method of selecting a subscriber subscribed to a specific service and paging to a specific subscriber located closest to the location information service sender among the specific subscribers. This is a procedure for providing an application service using the present invention technology, such as police call service, transportation service (call taxi, etc.), emergency insurance service, security personnel service, services for the purpose of delivery (food, flowers, goods, etc.) in an emergency situation. ), It can be used for application services such as moving service and product after-sales service.

4A and 4B are diagrams illustrating an exemplary embodiment of a call processing method using a multiple or selective paging procedure according to an embodiment of the present invention, in which a location of terminals joined to a specific group is searched and simultaneously paged to a specific paging area (Aera) It relates to a method for providing a location information service. For simplicity, the description will be made here without distinguishing the equipment of the called / calling side.

When the mobile terminal 41 transmits a location service request message to the base station / base international controller 42, the base station / base international controller 42 sets up a call for the location service to the mobile exchange 43. After receiving the call, the mobile switch 43 proceeds with the call to the base station / base international controller 42 and requests the allocation of a channel at the same time, and then requests the location information service server 45 for the service of the location information.

Subsequently, when the mobile switch 43 receiving the response from the location information service server 45 requests the called terminal location to the subscriber home location register 46, the subscriber home location register 46 routes to the subscriber visit location register 44. Make a request for information. When the requested subscriber visit location register 44 requests routing information from the mobile switch 43, the mobile switch 43 searches for the subscriber information and then notifies the subscriber visit location register 44 of the search result again. Then, the subscriber visited location register 44 notifies the subscriber home location register 46 of the routing information, and the notified subscriber home location register 46 notifies the mobile switch 43 of the location of the called terminal. The base station / base international controller 42 also notifies the mobile switch 43 that the channel has been allocated. At this time, the mobile switch 43 includes an ISUP (ISDN USER PART) head address message.

On the other hand, after performing multiple / selective paging between the mobile station 47 where the base station / base international controller 42, which has received the multiple / selective paging request from the mobile exchange 43, performs multiple / selective paging to the mobile exchange 43 In response to the paging, the mobile exchange 43 requests to establish a call and transmits it to the base station / base international controller 42.

Subsequently, when the base station / base international controller 42 responds to the call setup by the mobile switch 43, the mobile switch 43 again requests the base station / base international controller 42 to allocate a channel. In this way, when the channel assignment between the base station / base international controller 42 and the mobile terminal 47 is completed, the mobile terminal 47 responds to the destination terminal, the base station / base international controller 42 also the mobile exchange 43 Answer. At this time, the mobile switch 43 responds to the base station / base international controller 42 including an ISUP (ISDN USER PART) address completion message (ACM).

When the mobile station 47 requests the base station / base international controller 42 to connect a call, the base station / base international controller 42 responds to the mobile terminal 41 and then sends a response to the base station to the mobile terminal 47. The base station / base international controller 42 requires the mobile switch 43 to connect the call. At this time, the mobile switch 43 includes an ISUP (ISDN USER PART) response address message (ANM). Accordingly, the mobile switch 43 transmits a connection response and a request for an ISUP (ISDN USER PART) response address message (ANM) to the base station / base international controller 42, and transmits the transmitted request to the mobile terminal 41. Finally, the base station / base international controller 42 responds to the connection to the mobile exchange 43.

Subsequently, it is determined whether the location information service subscriber exists in the caller's cell / sector (area i).

As a result of the determination, if the subscriber does not exist, it is determined whether the time has elapsed (510). If the subscriber exists, the caller's cell (i region) is requested to multiple or selective paging according to the service requested by the sender (506). Check if there is a response (507).

As a result of the check, if there is a response, a call is set (508). If there is no response, it is checked whether the number of times for the paging request is greater than N (a predetermined number) (509).

If it is not large, the process proceeds to step 506 of requesting multiple or selective paging of the caller's cell (region i). If it is large, it is checked whether time for a paging response has elapsed (510).

As a result of the check, if the time elapses, the service message is transmitted (511) and then disconnected (512).

As a result of the check, if the time has not elapsed, the caller's cell is increased to make the caller's neighbor cell (513).

Subsequently, the location information service subscriber in the caller's neighbor cell (region K) is searched (514), and the location information service subscriber in the caller's neighbor cell (region K) is checked (515).

As a result, if it does not exist, it increases the sender's cell to make the caller's neighbor cell (513) .If it exists, it requests multiple or selective paging depending on the service requested by the caller in the neighbor's cell (K region). After 516, it is checked whether there is a response to paging (517).

As a result, if there is a response, the process proceeds to the process of setting up a call (508). If there is no response, it is checked whether the number of times for the paging request is greater than N (a predetermined number) (518).

As a result of the check, if it is not large, the process proceeds to requesting multiple or selective paging of the caller's neighbor cell (region K) (516).
