JPH07162943A - Digital mobile equipment for car/portable telephone - Google Patents

Abstract

PURPOSE:To exactly determine the position (latitude/longitude) of the portable equipment for digital car/portable telephone when registering the position of the mobile equipment. CONSTITUTION:The latitude/longitude of a mobile equipment 1 is measured by a portable (on-vehicle) GPS receiver 5 and registered on the position memory of the mobile equipment 1. This latitude/longitude information is transmitted to a radio base station 2 together with a conventional position registering request message and registered through a mobile communication switchboard 3 onto a home location register 4. A dedicated line is connected to the mobile communication switchboard 3 so as to extract the information registered on the home location register 4 and to utilize it for various kinds of service. Thus, a gray zone generating a line connection error in a unit of administrative organization, such as police, controlled by prefectures, can be canceled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile device for digital automobiles and mobile phones, and more particularly to a location registration control system for mobile communication.

[0002]

2. Description of the Related Art Conventional location registration is used for the purpose of efficiently calling mobile stations by focusing on a certain area.

FIG. 2 is a diagram for explaining a conventional position registration control operation in a mobile communication system. Mobile device 1 (MS
1) is a device that is a terminal of a wireless line and provides a mobile communication service to mobile subscribers. Radio base station 2
(BTS2) establishes a wireless connection with MS1. The mobile communication switching center 3 (MSC3) is a switching center that performs call connection control, service control, etc. in order to provide mobile communication services. Home location register 4 (HLR4)
Is a database that guarantees the mobility of subscribers and mobile stations and manages subscriber information and mobile station information necessary for providing services to subscribers.

Next, the operation will be described. In the digital car telephone system, the MS 1 receives the position number message in the broadcast information message from the BTS 2 and compares it with the position number on the memory so far. The position number is a control zone number including a plurality of wireless zones. When a difference occurs, the location registration request is sent to MSC3, and MSC3 sends H
Location registration is performed in LR4. Also, the position memory stored in the MS 1 itself is rewritten. In addition to the above, this operation is also performed at regular time intervals.

[0005]

Since the conventional position registration is performed in units of control zones, it is not possible to know the accurate position of the mobile device. Therefore, when the control zones overlap in the administrative field as shown in FIG. 3, the mobile station may be connected to the exchange station on the administrative B side even if the mobile station is on the administrative A side, depending on the radio wave propagation situation. Such overlapping parts of control zones (called gray zones) on the administrative level are not a problem for general use, but for example, in the case of the 110 police report of prefectures, the above cases , I had to connect to the police of administration A, but I got connected to the police of administration B, so again administration A
There was a problem that I had to reconnect to him.

[0006]

In order to solve the above-mentioned problems, the digital car / mobile phone mobile device of the present invention receives latitude / longitude information from a portable (including in-vehicle) GPS receiver, It has a function of transmitting to the radio base station together with the conventional location registration request message.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, a portable (including in-vehicle) GPS receiver 5 receives signal radio waves from an artificial satellite for the global positioning system, measures the current latitude and longitude, and obtains the information from the mobile device 1
(MS1). Base station controller 6 (BSC6)
Has functions of radio management, channel switching control, radio system maintenance and operation, etc. within the control zone of the BSC 6. The police lines 7a and 7b are dedicated lines connecting the police trunk in the MSC 3 and the device in the police command room 8. Police command room 8a,
8b receives and displays the data of MS1 from HLR4.

Next, the operation of the system shown in FIG. 1 will be described. In this embodiment, it is assumed that the mobile device is in the gray zone as shown in FIG. GPS receiver 5 to MS1
Then, the latitude / longitude information is transmitted and registered in the position memory in the MS 1. At the same time that the MS 1 goes off-hook, in addition to the conventional position information request message, latitude / longitude information is transmitted by radio waves to the BTS 2 and transmitted to the MSC 3.
The MSC 3 registers the location with the HLR 4. HLR4 is
The mobile unit number of the MS1, the calling zone number of the mobile unit, and the latitude / longitude information of the mobile unit are written in the memory in the HLR4. The location registration is performed not only at the time of off-hook, but also at intervals arbitrarily set by the communication carrier in the same manner as described above. When the mobile device makes the 110th call, MSC3 sends HLR4
Calculate based on the latitude / longitude information stored in
Determine which administrative division MS1 is in. If M
If S1 is in a different administrative division from the police line 7a, MS
Connect to the police line 7b on the administrative division side of 1. Also,
Based on the latitude / longitude information obtained from the HLR 4 through the MSC 3 and the police line 7b on the police side, the police command room 8b displays the position of the sender (MS1) on the map or the address.

Next, another embodiment of the present invention will be described. Figure 1
Replacing the police line 7 and police command room 8 with a dedicated line and company command room. For example, a carrier is a shipping company (including courier service)
Then, the mobile number and latitude / longitude information of the mobile can be obtained from the HLR 4 through the dedicated line,
If the number and position of the mobile device can be displayed in the company command room, it becomes possible to manage the operation of the transportation vehicle equipped with the mobile device.

[0010]

Since the position of the mobile device can be accurately measured by using the GPS receiver, the gray zone in the 110th call can be eliminated, and the position of the sender can be accurately confirmed on the police side. The effect is that you can respond quickly.

Further, by connecting a dedicated line to another company, it can be applied to operation management and the like.
