Abstract

PROBLEM TO BE SOLVED: To improve the probability that a system can be connected to a composite portable terminal, even if an operation mode is switched accompanying movement by connecting a call request to the home station device of a fixed telephone number, when the composite portable terminal exists in the communication available area of the home station device. SOLUTION: When PHS terminals 261 and 262 exist in a house and are operating in a home mode, a call request is transferred to a fixed telephone number allocated to a home station device 200 instead of a PHS telephone number, if the call request for the PHS telephone number from a calling terminal 410 is detected. Such transfer control is realized through the special operation of a local switchboard 100 and an SCP station 300. A local switchboard 100 is connected to the SCP station 300 via a common line signal network 440. Thus, a caller has only to dial the PHS telephone number of an opposite composite portable terminal without being concerned whether or not an opposite party is at home.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a personal handyphone system (PHS) using a public communication system.
Communication control method and apparatus for calling a composite portable terminal (hereinafter, referred to as a PHS terminal) having a function of a terminal and a function of a cordless phone slave unit wirelessly connected to a self-service communication system called a home station. .

[0002]

2. Description of the Related Art A PHS terminal has a public mode and a home mode as operation modes. The PHS terminal
It operates in either a public mode or a home mode by switching a manual switch provided therein or by automatic selection control. A PHS terminal operating in the public mode can communicate with any other terminal via a wireless base station of a public communication system. In this case, the PHS terminal is used with a unique number (PHS telephone number) assigned in advance as a cordless telephone outdoors.

[0003] A PHS terminal operating in the home mode wirelessly communicates with a self-operating communication system called a home station. That is, the PHS terminal operates as a cordless handset of the home cordless telephone, and the home station installed in the home operates as a self-operated base station. By switching the manual switch, or in a home where the radio wave of the private communication system is stronger than the radio wave of the public communication system
When the S terminal is arranged and the PHS terminal is operating in the home mode, if the PHS terminal is to be called from any terminal by its PHS telephone number, the communication between the public communication system and the PHS terminal is stopped. The line cannot be established, and the calling terminal is notified as "out of service area".

[0004] In such a case, in order to talk with the PHS terminal operating in the home mode, the caller must call the PHS terminal of the other party.
It is necessary to connect to the fixed telephone number (parent station number) of the self-service communication system including the HS terminal via the public communication system. In addition, JP-A-8-195983 discloses that
If the terminal number of the called terminal specified by the caller is the portable terminal number of the cordless telephone handset, the base station is searched from the terminal number, and the subscriber telephone reaching the called handset via the base unit. It is disclosed that a means for establishing a line is provided on the network side.

[0005]

In recent years, telephone numbers have been desired to be used as numbers for calling specific individuals rather than as numbers for specifying each home, and so-called "chasing telephone" functions have been considered. I have. This type of function is realized or prepared as a “transfer telephone service”, a “PID service”, or the like.

However, in this type of service, every time the transfer destination is changed, it is necessary to re-register the transfer destination with an exchange, an SCP station (service control station) or a terminal device, which is troublesome. There is. Also, the service could not be properly received due to forgetting to operate. Further, unless the transfer destination is updated frequently, a call received while moving is received at another place in the past, so that the call cannot be made.

[0007] On the other hand, a wireless mobile phone or mobile phone has the convenience of being able to connect immediately regardless of where it is and to be able to talk. Even in the PHS terminal, if the PHS number is publicized, the communication area is smaller than the mobile phone,
Although it cannot be used during high-speed travel, similar services can be expected. However, in the case of the PHS terminal, when the home antenna is used, the PHS terminal automatically switches to the home mode in the house, and therefore, there is a disadvantage that the PHS telephone number cannot be used to receive a call. In this case, an announcement to the effect that "out of service area" or "power is off" is input to the terminal of the caller.

There is a transfer function to prevent this. However, on the receiving side, the transfer function does not always function because of the inconvenience and the possibility of forgetting the operation as described above. In addition, if the calling side makes a call to the PHS telephone number and is not connected "out of service", it will be necessary to call the home fixed telephone again considering the possibility of being at home, which is troublesome. In addition, the caller needs to remember both the PHS telephone number and the landline telephone number of the other party.

An operation example of the current PHS service will be described. In the example shown in FIG. 9, first, PHS terminal # 1 exists in the communication area of base station #B, and PHS terminal # 2 exists in the communication area of base station #C. Here, when the caller transmits the PHS telephone number of PHS terminal # 1 in order to communicate with PHS terminal # 1, the local exchange on the transmitting side transmits SHS.
The PHS telephone number is sent to the CP station to request a number conversion. In response to this request, the telephone number of the PHS connection device is returned from the SCP station as position information, and the local exchange on the calling side reconnects to the PHS connection device by using this telephone number.

At this time, the PHS connection device has the P
The HS phone number is also sent. The PHS terminal # 1 sounds because the base station makes a general call using the PHS telephone number. By responding to the incoming call, a call between the PHS terminal # 1 and the calling side becomes possible. On the other hand, when the owner of PHS terminal # 1 returns home and PHS terminal # 1 enters the area of the home station, PHS terminal # 1 is in the zone of base station #A.
The switching of the manual switch or the automatic switching of the HS terminal # 1 causes the PHS terminal # 1 to enter the home mode. That is,
Since the PHS terminal # 1 is a cordless phone slave unit, the PHS terminal # 1 is not connected to the PHS terminal # 1 at this time.

In such a case, Japanese Patent Application Laid-Open No. 8-195983
Utilizing the transfer function as shown in Japanese Patent Publication No.
Since the telephone number is automatically converted to the fixed telephone number of the home station, it is possible to connect to the PHS terminal # 1.

However, when the PHS terminal # 1 moves out of the area of the home station, the PHS terminal # 1 switches to the public mode again, so that the call received at the fixed telephone number of the home station is not transmitted to the PHS terminal # 1. When the transfer function is used, the PHS terminal #
1 and a plurality of cordless phones connected to the home station receive an incoming call, and all of the cordless phones connected to the home station ring. It is also likely that a person will respond.

The present invention provides an integrated communication for calling a composite portable terminal (PHS terminal) having a function of a terminal of a personal handyphone system and a function of a cordless phone slave unit wirelessly connected to a predetermined home station apparatus. It is an object of the control method and apparatus to increase the probability of being able to connect to a composite portable terminal even when its operation mode is switched with the movement of the composite portable terminal, and to eliminate the need for a user to perform an update operation such as a transfer function.

[0014]

A first aspect of the present invention is to call a composite portable terminal having a function of a terminal of a personal handyphone system and a function of a cordless phone handset which is wirelessly connected to a predetermined home station apparatus. In the integrated communication control method of (1), if a call request for the composite portable terminal based on the terminal number of the personal handyphone system is detected on the exchange side, whether the composite portable terminal is present in the communicable area of the home station device? If the composite mobile terminal is present in the communicable area of the home station device, a fixed number assigned to the home station device based on the number of the personal handyphone system terminal of the call request is identified. Detect the telephone number and send the call request to the fixed telephone Characterized by connecting to the issue of the home station apparatus.

That is, when the composite portable terminal (PHS terminal) exists in the communicable area of the home station device, it is regarded that the composite portable terminal is operating in the home mode. Then, a fixed telephone number assigned to the home station device is detected based on the number of the terminal of the personal handyphone system of the call request, that is, the PHS telephone number, and the call request is connected to the home station device of the fixed telephone number.

Since such a transfer operation is performed only when the composite portable terminal is present in the communicable area of the home station device, the transfer operation is automatically executed and performed as the composite portable terminal moves. Release is performed. Therefore, even when the user moves, the user does not need to perform an operation for updating the transfer destination. According to a second aspect of the present invention, in the integrated communication control method according to the first aspect, a correspondence relationship between a position where the home station device exists and a communicable zone of a specific base station of the personal handyphone system to which the position belongs is defined as a first relationship. The correspondence between the location of the complex portable terminal and the communicable zone of a specific base station of the personal handyphone system to which the location belongs is sequentially detected as second information, and It is characterized in that it is determined whether or not the composite portable terminal is present in the communicable area of the home station device based on a result of comparing the first information and the second information.

Since the home station device is installed in the home, its location can be regarded as constant. In addition, a specific base station whose area including the position of the home station device is set as a communication available zone can be known in advance. Therefore, these correspondences are stored in advance as first information. Further, in this type of communication system, since the location registration control of the composite portable terminal is performed, it is possible to know the communicable zone of the specific base station including the location of the composite portable terminal. Therefore, these correspondences are detected as the second information.

If the first information and the second information match, a base station having a communicable zone including the location of the composite portable terminal and a communicable location including the location of the home station are included. Since the base station having the zone is the same, there is a high possibility that the composite portable terminal is present near the home station device. Therefore, based on the result of the comparison between the first information and the second information, it is determined whether or not the composite portable terminal exists in the communicable area of the home station device.

According to a third aspect of the present invention, in the integrated communication control method according to the first aspect, when the composite portable terminal does not exist in the communicable area of the home station device, the call request is transmitted to a personal handyphone system number. It is characterized by connecting to a terminal. According to a fourth aspect of the present invention, in the integrated communication control method according to the first aspect, when a call request is connected to the home station device of the fixed telephone number, an incoming signal sent from the local exchange on the receiving side to the home station device includes: It is characterized in that the terminal number of the personal handyphone system is superimposed.

In this manner, the home station device can know the number of the terminal of the personal handyphone system that has received the call. Based on this number, the home station device can identify the specific handset that has been called from the plurality of handset. Claim 5

0 and the channel control device 130. P shown in FIG.
Each of the HS terminals 261 and 262 operates in one of the public mode and the home mode. This operation mode is determined by the state of a manual mode switch (not shown) provided in each of the PHS terminals 261 and 262, or by automatic mode switching control. In the automatic mode switching control, the operation mode is switched according to the intensity of the radio wave from the public base station 430 and the intensity of the radio wave from the home station device 200 received by each of the PHS terminals 261 and 262.

Therefore, each of the PHS terminals 261 and 262
When it is present in the owner's home, the home mode is set, and the home station device 200 installed in the home operates as a cordless phone slave unit. In that case,
When there is an incoming call to the fixed telephone number assigned to home station apparatus 200, PHS terminal 261,
At 262, a ringing tone sounds.

On the other hand, the PHS terminal 2
When 61 or 262 is taken out of the house, PHS terminals 261 and 262 operate in the public mode. In the case of the public mode, communication between the home station device 200 and the PHS terminals 261 and 262 becomes impossible. instead,
When a call request is issued to a specific PHS telephone number assigned to each of the PHS terminals 261 and 262, the PHS terminal 261 or 26 via the local telephone exchange 100, the PHS connection device 420 and the public base station 430.
2 is called.

For example, from the transmitting terminal 410 shown in FIG.
When the PHS telephone number assigned to the HS terminal 261 is dialed, the local telephone exchange 10
0, a call request for the PHS terminal 261 is generated via the PHS connection device 420 and the public base station 430. However, when the PHS terminal 261 is at home and is operating in the home mode, the PHS terminal 261 cannot receive a call request from the public base station 430. Does not connect.

In the communication system of this embodiment, PH
When the S terminals 261 and 262 are at home and operating in the home mode, upon detecting a call request for a PHS telephone number from the calling terminal 410, the terminal is assigned to the home station device 200 instead of the PHS telephone number. The call request is forwarded to the fixed telephone number. Such transfer control is performed by the local telephone exchange 100 and the SCP.
This is realized by the special operation of the station 300. The local telephone exchange 100 is connected to the SCP station 30 via the common channel signaling network 440.
0 is connected.

As shown in FIG. 1, the local telephone exchange 100 has a communication path connection device 110, a PID transmission / reception storage device 12
0, communication path control device 130, position information transmitting / receiving device 140
And a common channel signaling network controller 150. The SCP station 300 includes a network control device 310, a reception control device 320, a search device 330, a storage device 340, a comparison device 350, and a translation information transmission device 360.

In the storage device 340 of the SCP station 300,
A number conversion table as shown in FIG. 2 is formed.
Referring to FIG. 2, an area for holding five types of data D0, D1, D2, D3, and D4 for each user is formed in the number conversion table. In this number conversion table, the data D0 is the PHS terminal 261 (26
2) PHS phone number. The data D1 is current position information of the PHS terminal 261 (262), and specifically, is a telephone number indicating the last public base station 430 whose position has been registered. The data D1 is sequentially updated as the PHS terminal 261 moves.

The data D2 is stored in the home station device 2
00, specifically, a telephone number indicating the public base station 430 closest to the home where the home station device 200 is installed. Data D3 is a fixed telephone number assigned to home station device 200. For example, from the transmitting terminal 410 in FIG.
When you dial the landline number 3
A communication line with the home station device 200 can be established via the “00”. The data D4 is information indicating an attribute of the user, and is information indicating whether or not the user is permitted to use the service.

When data is first registered in the number conversion table, the data input from the data input device 470 shown in FIG. 1 is transmitted via the SMP station (network service control station) 460 connected to the packet network 450. It is downloaded to the SCP station 300 and stored on the storage device 340. Also,
The data D1 on the number conversion table is sequentially updated by the position registration control shown in FIG. 3 as described below. In FIG. 3, the position information of the base station transmitted from the public base station 430 in step S21 is stored in the PHS terminal 261 (262).
Is received in step S11.

The PHS terminal 261 (262) refers to the previously stored base station position information in step S12.
In the next step S13, the latest position information of the base station detected in step S11 is compared with the past position information referred to in step S12. It is determined in step S14 whether the result of the comparison in step S13 matches or does not match. For example, when the PHS terminal 261 (262) hardly moves, position information from the same public base station 430 is repeatedly received, so that the comparison result is identified as a match in step S14.

When the PHS terminal 261 (262) moves across wireless zones of a plurality of public base stations 430, the PHS terminal 261 (262) transmits position information from different public base stations 430. Since it is received, a mismatch is detected in step S14. If there is no match in step S14, the PHS terminal 261 (262) sends a position registration request to the public base station 430 forming the wireless zone including the current position in the next step S15.

When detecting the location registration request from PHS terminal 261 (262) in step S22, public base station 430 transfers this request to SCP station 300. In this case, in step S31, the SCP station 300 updates the data D1 indicating the correspondence between the PHS terminal 261 (262) that sent the location registration request and the public base station 430. That is, the PHS terminal 261 (26
The telephone number of the public base station 430 is stored as the position data D1 corresponding to the PHS telephone number (D0) of 2).

For example, if the PHS telephone number (D0) of the PHS terminal 261 (262) that sent the location registration request is "05"
0-123-4568 ", the data string of the user X2 corresponds in the example of the number conversion table of FIG.
The telephone number of the public base station 430 that has transmitted the location registration request as the data D1 of the user X2 is "03-5555-6".
789 ”.

Accordingly, the data D1 in the number conversion table of FIG. 2 is the telephone number of the public base station 430 indicating the current position of the PHS terminal 261 (262) to which the PHS telephone number indicated by the data D0 is assigned. Also, for example, like the data string of the user X1 in the number conversion table shown in FIG. 2, the content of the data D2 is "03-5555-1234".
When the content of the data D3 is equal to “03-5555-1234”, the PHS terminal 261 (262) and the home station device 200 are located in the same wireless zone of the public base station 430. That is, in that case, P
The HS terminal 261 (262) is the home station device 2
00 and can communicate with each other.
The operation mode of the terminal 261 is the home mode).

In any case, the PH of the PHS terminal 261
Since the S telephone number corresponds to the data D0, the data D1, D2, D3, and D4 of a specific user can be searched from the number conversion table of FIG. 2 using the PHS telephone number as an index. In the number conversion table shown in FIG. 2, the data D2 and D3 of the data string of the user X3 who has not obtained the permission of this service have not been registered.

In the communication system shown in FIG. 1, the operation when dialing the PHS telephone number of PHS terminal 261 from calling terminal 410 will be described below. In this case, in the local telephone exchange 100, the PID transmission / reception storage device 120 contained therein is
The telephone number is held, and a number translation request is sent to the SCP station 300 via the common channel signaling network control device 150 and the common channel signaling network 440 together with the PHS telephone number.

Upon receiving this number translation request, the SCP station 3
00 executes the translation processing shown in FIG. That is, when a number translation request is received, the process proceeds from step S41 to S42.
In step S42, a set of data D assigned to a specific user is referred to by referring to the number conversion table of the storage device 340 using the received PHS telephone number as an index.
1, D2, D3, and D4 are acquired.

For example, when the number conversion table shown in FIG. 2 is used, the received PHS telephone number is "050-
123-4567 ", the data of the user X1 is acquired, and the received PHS telephone number is" 050-1 ".
23-4568, the data of the user X2 is acquired, and the received PHS telephone number is "050-12".
In the case where it matches "3-1234", the data of the user X3 is acquired.

In step S43 of FIG.
The data D4 obtained in step 2 is checked to determine whether or not the user has permission for the service. For example, in the case of the users X1 and X2 in FIG. 2, since the data D4 is "1", it is determined that there is permission, and the process proceeds to step S44.
In the case of 3, since data D4 is "0", it is determined that there is no permission, and the process proceeds to step S46.

In step S44, it is determined whether or not data D1 and data D2 match in the set of data obtained in step S42. If they match, that is, if the position of the PHS terminal 261 is
0 and within the wireless zone of the same public base station 430, the PHS terminal 261 and the home station device 20.
If there is 0, the process proceeds to step S45.

When data D1 and data D2 do not match, that is, PHS terminal 261 is located at a position distant from home station apparatus 200, and PHS terminal 261 and home station apparatus 200 are located in different radio zones of public base station 430. If there is, the process proceeds from step S44 to S46. In step S45, data D3 in the set of data acquired in step S42 is transmitted to local telephone exchange 100 via common channel signaling network 440. That is, the fixed telephone number of home station apparatus 200 registered in the number conversion table shown in FIG. 2 is notified to local telephone exchange 100 as a response to the number translation request from local telephone exchange 100.

In step S46, the data D1 in the set of data obtained in step S42 is
It transmits to the local telephone exchange 100 via 40. That is, as a response to the number translation request from the local telephone exchange 100, the telephone number of the public base station 430 that can currently communicate with the PHS terminal 261 is notified to the local telephone exchange 100.

For example, when using the number conversion table shown in FIG. 2, the received PHS telephone number is “050-12”.
If “3-4567”, the data D1 of the user X1 is equal to the data D2, so “03-3333-1234” of the data D3 of the user X1 is transmitted in step S45.

The received PHS telephone number is "050".
In the case of “−123-4568”, since the data D1 of the user X2 is different from the data D2, “03-5555-6789” of the data D1 of the user X2 is set in step S46.
Sent by Also, the received PHS telephone number is "05
In the case of "0-123-1234", since the data D4 of the user X3 is "0" (no permission), "026-123-4567" of the data D1 of the user X3 is set in step S4.
6 is transmitted.

The local telephone exchange 100 is connected to the SCP station 300

Since "3-1234" is the fixed telephone number of the home station apparatus 200, the communication path control apparatus 130 controls the communication path connection apparatus 110 to connect the calling terminal 410 and the home station apparatus 200. An incoming signal is transmitted to the communication line controller 210.

In this case, the home station device 2
00 and the PHS terminal 261 are the same public base station 430
, The PHS terminal 261 is likely to be operating in the home mode. When receiving the incoming signal, home station apparatus 200 also wirelessly sends the incoming signal to PHS terminal 261 which is a cordless phone cordless handset via wireless communication control apparatus 220, wireless transmitting / receiving apparatus 230 and home antenna 240. , PHS
