Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call transfer system in mobile communication. In recent years, communication with mobile communication devices such as car phones and mobile phones has become widespread.

[0002] In these mobile communications, subscribers (including public telephones) of fixed communication networks or subscribers such as mobile subscribers (hereinafter, simply referred to as a sender) are transmitted to mobile subscribers. Makes a connection by dialing a mobile connection number composed of "mobile communication identification number + incoming mobile subscriber number".

In this case, the communication charge generally varies depending on the distance between the caller and the terminating mobile subscriber.
In the case of mobile communication, since the caller cannot know whether the mobile subscriber of the communication partner is in a short distance or a long distance, the communication charge becomes unexpectedly high and may cause a complaint. .

In order to prevent such a problem, the mobile communication identification number is changed according to the distance between the caller and the terminating mobile subscriber (actually, the distance between the charge calculation points of the originating and receiving stations). A method has been adopted in which by selecting a mobile communication identification number, connections to mobile subscribers who are outside the range determined by the selected mobile communication identification number are restricted.

For example, in the case of an automatic telephone, "030+" is used to connect to a car telephone at a distance of less than 160 km.
Incoming mobile subscriber number (eg 7 digit number) ", 160
"040+" for car phones over a distance of more than km
It is decided, for example, to dial the "incoming mobile subscriber number", and if there is no incoming mobile subscriber within that range, a talkie etc. is used to notify that there is no called mobile subscriber. ing.

On the other hand, also in mobile communication, there is a call transfer service for transferring a call received by a mobile subscriber to another mobile subscriber designated in advance. in this case,
The communication fee from the caller to the station where the transfer source mobile subscriber is located is borne by the caller, and from the station where the transfer source mobile subscriber is located to the station where the transfer destination mobile subscriber is located. The communication fee will be borne by the transfer source mobile subscriber.

However, in the conventional call transfer system,
Since the transfer source mobile subscriber registers the transfer destination with the mobile connection number, that is, "mobile communication identification number + destination mobile subscriber number", transfer is performed with the transfer source mobile subscriber. The distance between the preceding mobile subscribers will be determined by the registered mobile communication identification number.

Therefore, if the transfer destination mobile subscriber moves out of the distance range determined by the mobile communication identification number registered by the transfer source mobile subscriber, the caller to the transfer source mobile subscriber is notified to the caller. As a result, a talkie indicating that the transfer destination mobile subscriber is not located is transmitted, and there is no means for the caller to change the mobile communication identification number and connect to the transfer destination mobile subscriber.

From the above, there is a need for an incoming call transfer system which enables transfer even if the transfer destination mobile subscriber moves out of the distance range defined by the mobile communication identification number.

[0010]

2. Description of the Related Art FIG. 5 is a block diagram of a mobile communication system. The mobile communication system shown in FIG. 5 will be described below by taking an example of a car telephone system. First, a case where a subscriber 32 in the fixed communication network 30 communicates with a mobile subscriber (car phone A) 23. explain.

A subscriber (hereinafter referred to as a caller) 32 of a fixed communication network accommodated in a subscriber exchange 31 of the fixed communication network 30 has a predetermined car telephone identification number (mobile communication identification number).
And dial the number of the mobile subscriber 23. This car telephone identification number is "030" if the mobile subscriber 23 is less than 160 km away from the position of the caller 32 (specifically, the starting point of the toll band), and "040" if it is more than 160 km away. It is stipulated to use different numbers depending on the distance between the caller and the caller.

The mobile subscriber 23 is now 160
The caller 32 who thinks that the distance is less than km is "030 + mobile subscriber number (for example, 9022) as the mobile connection number.
Dialing "000)", the caller 32
From 31 the fixed communication network 30 is connected to the gateway exchange 2 of the mobile communication network 20, and the mobile connection number is received by the gateway exchange 2.

When the gateway exchange 2 identifies the number of the mobile subscriber 23 from the received mobile connection number, the mobile subscriber 23
The home memory station 26 storing the subscriber data of the mobile subscriber 23 is accessed to obtain data such as subscriber attributes necessary for connection, and the location registration information of the mobile subscriber 23 (details are publicly known in mobile communications. The current position of the mobile subscriber 23 is confirmed by () is omitted).

As described above, the mobile subscriber 23 becomes the mobile switching center.
When it is confirmed that the customer is in the wireless area 22, which is the receiving area of 21, the gateway switch 2 confirms the distance between the caller 32 and the mobile switch 21 having the wireless area 22 as the receiving area,
If it is less than 160 km, the incoming call is connected to the mobile switching center 21.

When the mobile switching center 21 receives the connection information, the mobile switching center 21 calls the mobile subscriber 23 via a radio base station (not shown), and if the mobile subscriber 23 responds, the caller 32 and the mobile subscriber 23 are called. A call is started with.

In the above, when the gateway switch 2 confirms the distance between the caller 32 and the mobile switch 21, the distance is 1
When the distance is 60 km or more, the gateway switch 2 does not perform the connection process and sends a "connection code guide notification talkie" from a talkie device (not shown). This connection code guidance notification talkie is a talkie that guides the called mobile subscriber 23 to reconnect with the car telephone identification number "040" because the called mobile subscriber 23 is not within 160 km which is connected with the car telephone identification number "030". Yes, it simply distinguishes from the "no-answer notification talkie" that notifies that the called mobile subscriber is not in the area.

The caller 32 hears the connection code guidance notification talkie, and if the mobile subscriber 23 wants to communicate even if the mobile subscriber 23 is at a distance of 160 km or more, he / she dials "040 + mobile subscriber number" again. It will be reconnected.

Next, call transfer in the prior art will be described. Now, the mobile subscriber 23 leaves the car,
An incoming call to the mobile subscriber 23 shall be forwarded to another mobile subscriber 25 when the car telephone is turned off.

When the mobile subscriber 23 (hereinafter referred to as the transfer source mobile subscriber A) starts the call transfer, the mobile subscriber 25 (hereinafter referred to as the transfer destination mobile subscriber B) is 160 k
If it is determined that the user is within the distance range of less than m, “call transfer identification number (eg * 19) + car phone identification number (eg 030) + transfer destination mobile subscriber B number (eg 90)
220001) "to register the call transfer. The distance between the transfer source mobile subscriber A and the transfer destination mobile subscriber B in this case is, for example, that the transfer source mobile subscriber A is in the service area. It is defined by the distance between the mobile switching center 21 (hereinafter referred to as the transfer source mobile switching center) and the mobile switching center 3 (hereinafter referred to as the transfer destination mobile switching center) in which the transfer destination mobile subscriber B is located. I shall.

At this time, the home memory station 26 which stores the subscriber data of the transfer source mobile subscriber A includes the current position information of the transfer source mobile subscriber A and the information indicating that the call transfer is in progress.
Memorized in.

In this state, when the caller 32 receives a call from the transfer source mobile subscriber A, the caller 32 is connected to the transfer source mobile switching center 21 in the same manner as described above. When the gateway switch 2 accesses the home memory station 26, it is confirmed that the incoming call to the transfer source mobile subscriber A must be transferred to the transfer destination mobile subscriber B, and this information is used as connection information. Transferring mobile switch
Delivered to 21.

When the transfer source mobile switching center 21 receives the above connection information, it accesses the home memory station 27 of the transfer destination mobile subscriber B and confirms the current position of the transfer destination mobile subscriber B. At this time, if the current position of the transfer destination mobile subscriber B is registered in, for example, the wireless area 24, the transfer source mobile switching center 21 determines the distance between itself and the transfer destination mobile switching center 3 which is in charge of the wireless area 24. If the distance is less than 160 km, the incoming call is connected to the transfer destination mobile switching center 3.

As a result, the transfer destination mobile exchange 3 calls the transfer destination mobile subscriber B, and if the transfer destination mobile subscriber B answers, a call is made between the caller 32 and the transfer destination mobile subscriber B. Is started.

However, when the transfer source mobile switching center 21 confirms the distance from the transfer destination mobile switching center 3, it is 160 km.
If the above is confirmed, the transfer source mobile switching center 21
Informs the caller 32 by means of a talkie (not shown) that the transfer destination mobile subscriber B is not in the service area.

In this case, the caller 32 is not connected to the transfer source mobile subscriber A or the transfer destination mobile subscriber B, but the transfer registration to the transfer destination mobile subscriber B is performed by the transfer source transfer. Since the call originator 32 cannot change the mobile communication identification number from “030” to “040”, the call originator 32 assigns it to the transfer source mobile subscriber A. Also results in no means to connect to the forwarding mobile subscriber B.

The exchanges 1 and 11 are installed at the position of the mobile exchange 21 of FIG. 3 and 4, the transfer source mobile subscriber is the transfer source mobile subscriber A or simply A, the transfer destination mobile subscriber is the transfer destination mobile subscriber B or simply B, and the transfer source mobile switch. Is referred to as station C, and the transfer destination mobile switching center is referred to as station D.

The operation flow of FIG. 3 will be described below with reference to FIGS. 1 and 5. In FIG. 5, when a mobile subscriber 23 (hereinafter referred to as mobile subscriber A) is present in the coverage wireless area 22 of the mobile switching center 21, the subscriber data of the mobile subscriber A is known by a known method. The location is registered in the home memory station ( _HA ) 26 in which a subscriber file (not shown) in which is recorded is stored, and the location information is recorded in the subscriber data.

In this state, when the mobile subscriber 23 transfers an incoming call to the mobile subscriber 25 (hereinafter referred to as the mobile subscriber B), the mobile subscriber A registers the call transfer (Fig. However, this registration is different from that described in the prior art, for example, "call transfer identification number (eg * XX) + transfer destination mobile subscriber B".
Number (for example, 90220001) ”.
Here, X of the call transfer identification number is an arbitrary number, * XX
Is a code for identifying that the call transfer is not restricted in distance unlike the call transfer in the prior art.

The registered contents of this call transfer are the mobile switching center 21
To the home memory station 26 and stored in the subscriber data. When, for example, a subscriber 32 (hereinafter referred to as a caller) of the fixed communication network 30 makes a call to the mobile subscriber A after the call transfer registration, the call is sent via the subscriber call 31 or the like to the mobile communication network 20.
Is connected to the gateway switch 2 (S2). When the gateway switch 2 identifies the incoming call to the mobile subscriber A from the received connection information, the home memory station of the mobile subscriber A is identified.
Access 26. Through this access, the gateway switch 2 confirms the position of the mobile subscriber A and also confirms that a request to transfer an incoming call to the mobile subscriber A to the mobile subscriber B is made (S3).

Next, the gateway switch 2 is a mobile switch 21 (station C) which is in charge of the wireless area 22 in which the mobile subscriber A is located.
(S4) to request a transfer connection to the mobile subscriber B. In response to this connection request, the mobile switching center 21 accesses the home memory station 27 of the mobile subscriber B, confirms the current position of the mobile subscriber B, and the mobile subscriber B determines the mobile switch.
It is confirmed that the mobile station 25 (station D) is in the wireless area 24 (S5).

The above confirmation is carried out by the transfer control means 4 of FIG. 1, and the confirmation result is sent to the mobile communication identification number creating means 6 via the transfer destination mobile body position confirmation means 5 and the transfer source mobile exchange. The distance between 21 and the destination mobile switching center 3 is confirmed. The mobile communication identification number creating means 6 selects the car telephone identification number based on the result. For example, if the distance between the two exchanges is less than 160 km, "030" is selected, and if it is 160 km or more, "030" is selected. And sends it to the connection control means 4 (S6 to S9).

When the connection control means 4 receives the car telephone identification number, it creates a mobile connection number together with the number of the transfer destination mobile subscriber B in the connection information received from the gateway switch 2, and uses this number. The transfer connection process is executed by using this (S10). By this transfer connection, the call is connected to the transfer destination mobile switching center 3 via the communication path network 7 of FIG. 1, and the transfer connection processing in the transfer source mobile switching center 1 ends. Thereafter, the transfer destination mobile switching center 3 calls the mobile subscriber B, and if the mobile subscriber B answers, the call with the caller 32 is started.

Next, the operation flow of FIG. 4 will be described with reference to FIG. 2 and FIG. 5. The call to the transfer source mobile subscriber A arrives at the mobile switching center 21 (station C) of FIG. The operation flow up to (S11 to S14) is the same as that in FIG.

Here, the mobile communication system shown in FIG. 5 is an automobile telephone system, and two automatic caller identification numbers are defined as mobile communication identification numbers (automatic caller identification numbers in this example). "030" when the distance is less than 160 km, "0" when the distance is 160 km or more.
It is defined that 40 "is used.

At the position of the mobile switching center 21 of FIG. 5, the transfer source mobile switching center 11 of the configuration of FIG. 2 is installed, but the initial mobile communication identification number creating means 15 of the transfer source mobile switching center 11 has the above-mentioned structure. Two automated telephone identification numbers "030" and "04"
It is assumed that "030" is set in advance from "0" as the first automatic telephone identification number.

When the mobile switching center 21 receives the connection information from the preceding switching system 2, the connection control means 14 of FIG. 2 identifies the initial mobile communication when starting the first connection processing to the transfer destination mobile subscriber B. The first automatic telephone identification number "030" is received from the number creating means 15, and the transfer destination mobile subscriber number in the connection information is added to this to create a mobile connection number. The connection processing for the transfer destination mobile subscriber is performed according to the connection number (S15 to S16).

The mobile communication identification number changing means 16 of FIG. 2 preliminarily sets "030" and "04" to the plurality of automatic telephone identification numbers.
The connection control means 14 stores the priority order in the order of "0" and stores it.
Monitors the mobile phone identification number and the information indicating the completion of the transfer connection from the information used during the connection process, but the connection control means 14 completes the transfer connection within a certain time after starting the first connection process. Is not received, the connection control means 14 changes the first car telephone identification number "030" used for the first connection processing to the next order "040" and outputs it to the connection control means 14 (S17). ~ S18).

The connection control means 14 performs the connection process again using this "040" and the transfer destination mobile subscriber number (S19).
However, when the connection is made to the transfer destination mobile subscriber B in these connection processes, the transfer connection process is completed. In the above, the car telephone identification numbers are "030" and "04".
There are two types, 0 ", but if there are two or more types, the above operation is repeated, and if the connection cannot be established even if the car telephone identification number is changed to the lowest priority number, the transfer destination mobile subscriber exists. The caller 32 is notified that the service is not available by means not shown.

As described above, in the present invention, the transfer-source mobile subscriber registers the call transfer without being aware of the distance between the transfer-source mobile subscriber and the transfer-source mobile subscriber. The caller connecting to the transfer destination mobile subscriber is connected to the transfer destination mobile subscriber regardless of the distance between the transfer source mobile subscriber and the transfer destination mobile subscriber. There is no possibility that a connection cannot be established because the distance condition of the subscriber does not meet.

Although the embodiment of the present invention has been described with reference to FIGS. 3 and 4, the configuration diagrams of FIGS. 3 and 4 and FIGS. 1, 2 and 5 used in combination are only examples of the present invention. However, the invention is not limited to what is shown in these figures.

For example, the effect of the present invention does not change even if all or some of the means of the mobile switching system shown in FIG. 1 or FIG. 2 are combined, and the mobile switching system has a configuration different from that of FIG. 1 or 2. Needless to say, it is possible to obtain the same effect as that of the present invention by modifying so as to comply with.

In the above description, the car telephone system is taken as an example, but the mobile communication system to which the present invention is applied is not limited to the car telephone system, and other mobile phone systems, etc. It is obvious that the present invention can be applied to the mobile communication system of No. 1 and that the numbers of the mobile communication identification number and the mobile subscriber number are not limited to the numbers and digits used in the above description. Is.

Further, in the above description, the transfer-source mobile subscriber registers the call transfer without designating the mobile communication identification number, but the mobile communication identification number is included as in the prior art. It is possible to easily carry out a procedure of performing registration and changing to the mobile communication identification number corresponding to another distance when the first incoming call transfer is performed in the transfer connection within the designated distance range and the user is not in the area. Also in this case, as in the above description, a different number from the conventional one is used as the call transfer identification number used when registering the call transfer in order to identify the call transfer including the change of the mobile communication identification number. It goes without saying that this distinction of the call transfer identification number enables the present invention to coexist with the call transfer method of the related art for limiting the transfer distance.

[0061]

As described above, according to the present invention,
The transfer-source mobile subscriber can perform call transfer without restriction on the distance to the transfer-destination mobile subscriber, and the transfer-destination mobile subscriber transfers because the transfer-destination mobile subscriber has moved within the distance range specified when registering the call transfer. There is no phenomenon that the call of the caller connecting to the original mobile subscriber cannot be connected to either the transfer origin mobile subscriber or the transfer destination mobile subscriber. Therefore, the utility of call forwarding in mobile communication is significantly improved.
