2. Description of the Related Art An exchange in a fixed telephone exchange system includes:
The control range is a small area around the subscriber's home, and the telephone number of the subscriber can be connected to the nearest police station or fire department for an emergency call. However, the switching system in the mobile communication switching system is different from the switching system in such a fixed telephone switching system, and its control range is configured across a plurality of cities and a plurality of prefectures, and can be connected to an emergency call. The emergency call reception desk (police station or fire station) is a predetermined specific place. Further, a common emergency call reception desk may be determined for each of a plurality of mobile exchanges.

Therefore, the emergency call connection processing in the conventional mobile communication switching system has been performed, for example, as shown in FIG. FIG. 3 is a system configuration diagram at the time of emergency call connection processing in a conventional mobile communication switching system.

In FIG. 3, three wireless areas 30, 31,
32 is a mobile exchange (ME) existing in the wireless area 31.
X) shows a case under the control of 50. And
Emergency call reception desks (OP) 26, 27, and 28 are arranged in the three wireless areas 30, 31, and 32, respectively.
6 shows a case where only the mobile switching center 6 is physically connected to the mobile switching center (MEX) 50. Three wireless areas 30,
The wireless base stations (BS) 10, 11, and 12 connected to the mobile switching center (MEX) 50 are provided at 31, 32.

In FIG. 3, a radio base station (BS) 11 in a radio area 31 relays a voice or a signal from a mobile terminal (MS) 51 located in the area, and a mobile exchange (MEX) 50. Is shown. This is the same in the other wireless areas 30 and 32.

A mobile switching center (MEX) 50 analyzes a connection partner and selects a connection line based on a request from a mobile terminal (MS) 51 sent via the radio base station 11. In the case of an emergency call, the connection operation to the designated emergency call reception desk (OP) 26 is executed in the example of FIG. Hereinafter, an outline of the emergency call connection process will be described.

For example, when the owner (subscriber) of the mobile terminal (MS) 51 in the wireless area 31 makes an emergency call, for example, an accident report (police) or a fire report (firefighting), the 110 Or dial 119 to make a call.

The transmission signal is transmitted to a radio base station (BS) installed in the radio area 31 where the mobile terminal (MS) 51 is located.
The data is sent to the mobile switching center (MEX) 50 via the communication terminal 11. When the mobile exchange (MEX) 50 recognizes that the call is an emergency call by analyzing the number of the special number, it selects an emergency call line designated for the number, and exists in the wireless area 30 via the emergency call line. To an emergency call reception desk (OP) 26 to be connected.

When the emergency call reception desk (OP) 26 responds, a communication line is established, and a conversation between the subscriber of the mobile terminal (MS) 51 and the person in charge of the emergency call reception desk (OP) 26 becomes possible. Become. The person in charge of the emergency call reception desk (OP) 26 specifies an emergency location through this conversation.

That is, since the subscriber of the mobile terminal (MS) 51 does not know to which area the emergency call reception desk is connected, the subscriber of the mobile terminal (MS) 51 talks with the person in charge of the emergency call reception desk (OP) 26 to know where. The user will know in detail whether or not he or she is connected to the emergency call reception desk in the area. Thereby, the person in charge of the emergency call reception desk (OP) 26 can identify the nearest emergency response person (police station, fire department), and in the example of FIG. 3, the emergency call reception desk (OP) ) 27.

[0011]

However, in the above-mentioned conventional emergency call connection processing method, it is often difficult to perform an emergency-conscious connection processing due to the following problems. .

The first problem is that if the caller does not know where he is, nothing is transmitted to the responder at the emergency call reception desk. For example, even if a person who is unfamiliar with geography, such as a traveler, sends an emergency call from a place where the place name is not displayed, such as a mountainous area, the location of the emergency call will not be reported, and the person at the emergency call reception desk will not be able to grasp the location. Spend a lot of time.

The reason is that in the case of a fixed telephone, it is possible to roughly estimate the location of the subscriber's telephone, that is, the location of the subscriber, from the telephone number notified to the emergency call reception desk. In this case, the telephone number and the location are irrelevant and cannot be estimated. In addition, in a situation where the wireless area covered by the mobile switching system covers several cities or the entire prefecture is covered, the person who responds to the emergency call reception desk cannot have any means for confirming the position.

[0014] The second problem is that communication between the caller and the person who responds to the emergency call reception desk does not go well because there is a difference in recognition of location information.

[0015] The reason is that the person who responds to the emergency call reception desk may be located in an area different from the area where the caller originates, and since it covers all areas, firstly, it needs large frame information such as municipal names. However, the originator of the emergency call may be in a hurry and tend to assume that he / she is connected to the nearest emergency call reception desk like a fixed telephone. For this reason, the more familiar with the area, the more detailed the starting address, intersection, store name, etc., will be explained, and it will take considerable effort to sort out this information and derive the target area. It cannot be said that the processing has been completed.

It is an object of the present invention to provide an emergency call connection process in a mobile communication switching system in which a caller (subscriber) of a mobile terminal does not need to know his / her own location to be located at an emergency call reception desk responder. It is an object of the present invention to provide a mobile communication switching system and an emergency call connection processing method capable of transmitting information.

The mobile exchange (MEX) 20 includes:
A message device (MSG) 24 is also provided, and voice editing of information such as a place name obtained from the map information device (DB) 23 is performed as a location, and the corresponding person of the emergency call reception desk 26 can be notified through the communication line of the exchange. I can do it. Next, an emergency call connection processing operation according to the present embodiment will be described with reference to FIG. FIG. 2 is a sequence diagram illustrating the procedure of the emergency call connection process according to the present embodiment. In FIG. 2, the mobile terminal (MS) receives the GPS signal (a) immediately after power-on, and constantly recognizes the location. In this state, when the caller (subscriber) dials the special number and makes a call (b), a connection request signal (c) including position information (numerical information) recognized as a special number as an emergency call (c)
Is sent.

The connection request signal (c) is sent to a mobile switching center (MEX) via a wireless base station. The mobile switching center (MEX) analyzes the special number included in the connection request signal (c) and recognizes it as an emergency call such as a 110 call.

Since the emergency call reception desk (OP) to be connected differs depending on the type of the emergency call, the mobile exchange (MEX)
A connection line corresponding to the special number is selected and a connection request signal (d) is transmitted. In the example of FIG. 1, the person in charge of the emergency call reception desk (OP) 26 receives a call by the connection request signal (d) (e).

At the same time, the mobile switching center (MEX) requests the map information conversion function (f), and sends the map information device a place name based on the location information included in the connection request signal (c) from the subscriber. To get the map information converted to the address and the address.

When the responder of the emergency call reception desk (OP) answers the call (g), a connection response signal is returned (h). The connection response signal (h) is transmitted to the mobile exchange (ME
X) and relay to the mobile terminal (MS) via the radio base station and the like (i), the communication path between the caller (subscriber) and the person in charge of the emergency call reception desk can be set.

Conventionally, the caller (subscriber) and the person in charge of the emergency call reception desk were immediately connected here. In the present embodiment, the message device (MSG) is first connected (j) when the communication path between the two is settable, instead of immediately connecting, and the caller (subscriber) of the mobile terminal is established. (K) plays a voice message indicating to which emergency call reception desk the mobile terminal (M) is connected.
The name of the place obtained from the map information of the estimated location in S) is converted into voice guidance and heard (m).

Thus, the caller (subscriber) of the mobile terminal can determine where the connection destination is, for example, the nearest police station,
It is possible to determine whether it is a centralized center in a remote place and to be conscious of how to talk (n).

On the other hand, the person in charge of the emergency call reception desk can reliably obtain the information of the caller (subscriber), such as the mobile terminal, the municipal name, the street address, etc. as the estimated location (p. ). The person in charge of the emergency call reception desk only needs to have a conversation centered on confirmation with the caller (subscriber) of the mobile terminal when the call is actually connected, and can grasp the gist accurately (q ).

As a result, in the example of FIG. 1, the person in charge of the emergency call reception desk (OP) 26 is the mobile terminal (MS) 1
Can easily and quickly know that the caller (subscriber) is in the wireless area 31 where the emergency call reception desk (OP) 27 is located, so that the emergency call reception desk (OP) 2
7 can be transferred.

As described above, according to the present embodiment, the location information recognized by the mobile terminal is converted into map information in the mobile exchange, and the emergency call receptionist is notified by voice as location information such as a place name. Therefore, even if a subscriber who cannot recognize his / her location and place name makes an emergency call, it is possible to notify the receptionist of the location of the emergency call, thereby improving the efficiency of the emergency call in consideration of the urgency of the emergency call. Good connection processing becomes possible.

In the above embodiment, the location information is recognized in the mobile terminal by receiving the GPS signal, but the wireless area information of the wireless base station can be used. In this case, there is only a difference in accuracy in conversion into map information, and this is not an essential problem of the present invention. Also,
Although the mobile switching center notifies the emergency call reception desk staff by a voice message, it is of course possible to adopt a configuration in which a screen is displayed on the emergency call reception desk.

Furthermore, the mobile switchboard notifies the mobile terminal of the emergency call reception desk connected to the mobile terminal by a voice message. However, in the present invention, it is sufficient to notify at least the emergency call reception desk. The mobile terminal caller (subscriber)
This is because it can be known from the person in charge of the emergency call reception desk. This notification to the mobile terminal can also be made by screen display.

[0036]
