Abstract

PURPOSE:To reduce the rate of ineffective use of a telephone network equipment by calculating a charging index from the combination between calling district information to which a Sent telephone subscriber temrinal equipment belongs and the present position checked from identification information of an opposite mobile terminal equipment included in the received dial information. CONSTITUTION:A central controller 22 in a mobile communication exchange 20 calculates the distance between a telephone set l and a mobile equipment 2 depending on the call district identification number received from a relay exchange 10 and the position information of the mobile equipment 2 Sent from a home mobile communication exchange 30 to decide the charging index corresponding thereto. The controller 22 compares the decided charging index with the charging index corresponding to the charging index identification number dialed by the telephone set l and sends the telephone number of the mobile equipment 2 to a mobile communciation exchange 40 accommodating a radio base station 50 communicated With the mobile equipment 2 When coincident. The exchange 40 calls the mobile equipment 2 to connect the call from the telephone set l. Thus, the convenience of the dial operation is improved and the rate of ineffective use of the telephone network installation is reduced. Further, the Subscriber number capacity is expanded.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention provides a system for transmitting phone calls from ordinary telephone subscriber terminals accommodated in a telephone network to mobile telephone terminals such as car telephone terminals, marine telephone terminals, etc. by dialing. It relates to a mobile communication system that connects calls, and in more detail,
If it is ideal to have an area-independent dialing mobile communication system that does not require the telephone subscriber terminal to estimate the area where the other party's mobile terminal is located and specify it by dialing, the present invention adopts a system that conforms to that system. This relates to a dial mobile communication system with no area coverage.

(Prior Art) Current area-specific mobile communication systems, such as car phone systems, require not only the identification information of the other party's mobile terminal but also the area where the terminal is likely to be specified by dialing.
In the ship telephone system, the call charge is determined according to the distance between departure and arrival [81] and the time required for the call, and is borne entirely by the caller. Because it was designed based on the policy that the dial number used should be 10 digits or less, in order to use the existing telephone exchange settings 0; Taking the telephone as an example,
The numbering plan is "OXO" (car telephone service identification number') + CD (2-digit area designation code') + EFGHJ
(a 5-digit subscriber number), and by dialing the caller's CD code, the calling area where the other party's car terminal was thought to be located was specified, and a call with the car terminal in question was only possible when the caller was within that area. .

Therefore, the other party's car terminal does not actually exist in the area corresponding to the CD code dialed by the caller.
If it is found that the other party's car terminal is located in a different area, the charging index (call rate rate) for the area where the other party's car terminal currently exists will be the same as the charging rate for the area of the CD code dialed by the caller. Even if the index was the same, it did not allow connections.

There is not a one-to-one correspondence between CD codes and billing indexes, and one billing index may be commonly assigned to several CD codes. The number is large compared to the types of indexes.

Therefore, if you specify an area using a charging index, the probability that the other party's mobile terminal to be connected is located in that area increases, but conventionally, the area was specified using a CD code, so the other party's mobile terminal is located in that area. In other words, the probability of being unable to connect to the other party's mobile terminal with a single dial operation increases, and as a result, the rate of invalid use of telephone network equipment increases, and There were problems such as a decline in the quality of service to subscribers (increased chances of being forced to repeat dialing).

[Problem that the invention seeks to solve]

Therefore, in the present invention, as mentioned above in the conventional area designated mobile communication system, there are many cases in which connection cannot be established with a single Guitol operation, resulting in a high rate of invalid use of telephone network equipment. , a decline in service quality for calling subscribers, etc., are issues that need to be resolved.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a mobile communication system that makes it possible to reduce ineffective use of telephone network equipment and improve the quality of service to subscribers.

[Means and effects for solving the problems] The present invention has the following features:
In order to achieve the above object, a mobile communication exchange is installed at the relay exchange level of the existing telephone network or at a higher level, and the mobile communication system I! ! ! ! In a mobile communication system that connects a call to a mobile telephone terminal via a telephone subscriber terminal and makes it possible to make a telephone call, the target area of the call seen from the telephone subscriber terminal is divided according to the call charge rate, and the area is divided in advance for each division. When a charging index is allocated and at least the identification information of the other party's mobile terminal and the charging index information allocated to the area where the mobile terminal is located are dialed from the telephone subscriber terminal, The mobile communications exchange to which this dial information is input via the relay exchange uses means related to this dial information to know the region (originating region) to which the telephone subscriber terminal that made the call belongs and stores it as the originating region information. At the same time, the actual current location of the mobile terminal is investigated from the identification information of the other party's mobile terminal included in the received dial information, and the actual location for the call is determined from the combination of the investigated current location and the originating area information. calculates the charging index of , compares the calculated charging index with the transferred charging index, and - if not defeated, sends the calculated charging index to the calling subscriber terminal as the correct index. The feature is that the call is notified, and if there is a match, the call connection operation to the other party's mobile phone terminal is further advanced.

In other words, the mobile communication system according to the present invention does not completely eliminate region designation, but instead adopts the designation of charging index instead of region designation, so it can be said that it is similar to the region-free dial mobile communication system. In this sense, it can be said to be a semi-area non-designated dial mobile communications system.

〔Example〕

The present invention will now be described in detail with reference to the drawings.

The figure is a block diagram showing one embodiment of the present invention.

In the figure, 1 is a telephone (calling telephone terminal), 2 is a mobile terminal (automobile terminal), 3 is a subscriber line exchange, 4 is a relay exchange on the way, 10 is the final relay exchange IAi, 11 is a communication path device, 12 is a central control unit, 13 is a register, 14 is a MF
(multi-frequency) signal transmitter, 15 is a medium line, 20 is a mobile communication exchange (the mobile communication (δ exchange) located closest to the telephone network that accommodates telephone a1, 21 is a communication path device, and 22 is a central control 23 is an MF (multi-frequency) signal receiver, 24 is a common line signal path, 25 is a common line signal path, 26 is a talkie device, and 30 is a home mobile communications exchange (as the home of mobile unit 2, Always store current location information etc. in its memory 3
3 is a mobile communications exchange N) stored in the mobile station 3, 31 is a communication path device, 32 is a central control unit, 33 is a memory, and 40 is a mobile communications exchange (located closest to the wireless base station 50 that can communicate with the mobile station 2). 41 is a communication path device, 42 is a central control device, and 50 is a wireless base station.

Currently, there are two levels of charge index, and they are called “OXO”.
The operation will be described below, taking as an example the case where the information is displayed as "and OYO".

Note that "OXO" and "OYO" are used not only to identify billing indexes but also as identification means for mobile communication services. It is also assumed that "OxO" represents a low rate charging index and "OYO" represents a high rate charging index.

If a general subscriber dials the billing index "OXO" and the telephone number of the mobile device 2 (for example, "2012345") from the telephone 1, the subscriber line exchange 3 uses the prior art to dial the trunk exchange Send the above dial information to machine 4,
Similarly, the relay exchange 64 sends the dial information to the final relay exchange 10.

When the central control unit 12 in the trunk exchange 10 receives the dialed number "X02012345" in the register I3 (the first O of "OXO" is absorbed on the way),
Identifying the route of the trunk line 15 from the trunk exchange 4,
Determine the calling area of the telephone (the billing area in our country is
(can be determined from the area code).

Next, the central controller 12 in the relay exchange [10
Activate the F signal transmitter 14 and call the nearby mobile communication exchange 8!
20, the received dialed digit “X020123
45" and the calling area identification number (for example, "422") of the telephone l determined earlier. The central control unit 22 in the mobile communication exchange 20 transmits the dialed number " ,
From “2012345”, the home mobile communication exchange 30 that holds the location information of the mobile device 2 is identified, and the common line signal path 24 is identified.
The mobile station 2 sends the telephone number "2012345" of the mobile station 2 via the mobile station 2 and requests the home mobile communications exchange 30 for location information of the mobile station a2.

Based on the received phone number "2012345" of the mobile device 2, the central control device 32 in the home mobile communication exchange 30 accesses the memory 33 and stores the location information corresponding to the phone number "2012345" of the mobile device 2. extract and share
Position information is sent to the mobile communication exchange 20 via the II line signal path 24.

The central control device 22 in the mobile communications exchange 20 identifies the telephone 8.1 based on the calling area identification number "422" received from the relay exchange alO and the location information of the mobile device 2 sent from the home mobile communications exchange 3o. The distance to the mobile device 2 is calculated, and a charging index corresponding to the distance is determined.

Next, the central controller 22 in the mobile communication exchange 20 transmits the charging index determined as described above to the charging index identification number "OxO" dialed by the caller (telephone [1)].
”, and if they do not match, that is, if “OYO” is correct as the charging index identification number, activate the talkie device 26 and relay and exchange “Thanks OYO, please fix it!” 10.4 and the subscriber line exchange 3 to make an announcement to the telephone 1.

In addition, in the case of defeat, the central control unit 22 in the mobile communication exchange 20 sends the common line signal path 2 to the mobile communication exchange 40 accommodating the radio base station 50 that can communicate with the mobile 62
5, the mobile device 2's telephone number "2012345" is sent. The central control device 42 in the mobile communication exchange 40 calls the mobile a2 via the wireless base station 50, and calls the telephone 1.
Connect calls from.

Regarding the billing method, if the subscriber line exchange 3 is an associate switch, the subscriber line exchange, and if it is a crossbar exchange, the transit exchange 4 uses the billing index identification number ``OxO''.
” and “OYO”, the charging index is determined and charging is performed.

In this embodiment, the case where there are two levels of charging index has been described, but even if there are three or more stages, the present invention can be implemented in the same manner by providing three or more types of charging index identification numbers.

In this embodiment, the first three digits are "OxO".

Although the method of identifying the charge index using "OYO") has been described, it goes without saying that it is also possible to identify it using four digits such as "0X01" and "0X02".

Furthermore, in this embodiment, a method has been described in which the existing telephone exchange identifies the calling area and sends the calling area identification number to the mobile communication exchange a20, but instead of the calling area identification number, -
The present invention can also be carried out by transmitting the caller's telephone number from the a-telephone and local line exchange to the mobile exchange, since this allows the mobile exchange to know the calling area.

Furthermore, by connecting the relay exchange 4 and the mobile communication exchange with a direct line, the mobile communication exchange can determine the calling area by checking from which relay exchange the billing index identification number and the telephone number of the mobile device are sent. It is also possible to identify
The present invention can also be carried out by such a method.

〔Effect of the invention〕

As explained above, according to the present invention, the region designation code (CD) used in the region designation method is abolished, and if the charging index matches, it is possible to trace and connect to the area where the mobile device is located. The convenience of dialing is improved, and the rate of invalid use of telephone assembly 01H is also reduced. Furthermore, since the conventional area designation code (CD) can be used as a subscriber number, there is an advantage that the subscriber number capacity can be greatly expanded.
