Field of the Invention [0002] The present invention relates to a cordless telephone system using a cordless telephone terminal compatible with public / office switching, and more particularly to a cordless telephone terminal for a public service network. Regarding the configuration to connect. 2. Description of the Related Art Today, digital private branch exchanges are provided with a PHS (Personal HandyPhone System) compatible with switching between public and business establishments.
A private branch exchange system accommodating the above has been put into practical use. In this private branch exchange system, a plurality of base stations are provided on the premises of a business office as a predetermined space, and a cordless telephone terminal (mobile terminal) as a PHS slave is accommodated via these base stations. I have. [0003] Generally, self-owned PHs housed under a digital private branch exchange (hereinafter simply referred to as PBX) at a business office or the like.
The S network, that is, the digital cordless telephone system network,
Mutual communication within the area (extension / incoming / outgoing) and communication with the general public network via the PBX (outgoing / incoming outgoing) are possible. [0004] However, the public P
In order to enable a mobile terminal registered in the HS network to receive a public PHS service in a so-called self-owned PHS network area in a business office, the upper PBX needs to recognize the public PHS mobile terminal and provide a dedicated public PHS. There is a problem that a network connection function must be provided. [0005] From such a point, it is desired that a private branch exchange does not need to newly add a function of connecting to the public PHS network or the like, and a private cordless system capable of connecting mobile terminals to the public PHS network is desired. Had been rare. [0006] The present invention employs the following structure to solve the above-mentioned problems. <Configuration 1> The present invention relates to a mobile terminal that can be used as a wireless telephone in a public PHS network and a cordless telephone handset to which an extension number is given in a predetermined area, and a mobile terminal in the area in which a predetermined routing number is determined. before performs outgoing call request to the public PHS network based on the routing number and outputs
Upon receiving the extension number, the mobile terminal performs extension reception processing.
In a private cordless system including a private branch exchange, when entering the area, the mobile terminal sends a location registration request information to the routing number and a location registration request formed by adding the telephone number of the public PHS network and the extension number of the area. When the private branch exchange receives the location registration request, the private branch exchange outputs the location registration request as a transmission request to the public PHS network connection device based on the routing number, and the public PHS network connection device receives the location registration request from the private branch exchange. each performs position <br/> location registration processing against the public PHS network by creating a table that associates the extension number of the telephone number and area of the public PHS network in the request, the destination from the private branch exchange When receiving the routing number to which the telephone number is added, a call is made to the public PHS network, and an incoming call request for the mobile terminal is received from the public PHS network. When extracts the extension number based on the table, <br/> and performs an incoming request including those extensions to the private branch exchange. An embodiment of the present invention will be described below in detail with reference to the drawings. << Specific Example >><Structure> FIG. 1 is a structural diagram showing a concrete example of a private cordless system of the present invention. As shown in the figure, the private branch cordless system of the present invention is installed in a private branch exchange (PB) in an office or the like.
X) There is a self-owned PHS network centered on one, that is, a so-called digital cordless telephone system.
S) 2 and a mobile terminal (PS) 3.
In addition, a public PHS network connection device (public service network connection device) 4 is provided between the PBX 1 and a public PHS network (specific public service network) 5. The public PHS network connection device has an ISDN interface function on the PBX connection side and a public PHS base station interface function on the public PHS network connection side. A private branch exchange 1 is a digital private branch exchange accommodating a mobile terminal 3 via a private PHS base station 2,
When a position registration request to the public PHS network 5 is received from the mobile terminal 3, a position registration request of the mobile terminal 3 and a telephone call of the public PHS network 5 are transmitted based on a routing number included in the position registration request. Outputs the number and the extension number in the self-owned PHS area (predetermined area) 100, that is, when a normal call is received from the mobile terminal 3.
And has a function of making a call request based on the routing number. The self-managed PHS base stations 2 are installed at various places in the business office and play a role as base stations for the mobile terminal 3. The area of the self-managed PHS base station 2 is the self-managed PHS area 100. The mobile terminal 3 is a PHS telephone having a function as a wireless telephone in the public PHS network 5 and a cordless telephone handset in a business office. This mobile terminal 3 has a self-owned PH
When the vehicle enters the S area 100, a function of performing a position registration operation using a predetermined routing number is provided. The public PHS network connection device 4 is a private branch exchange 1
This is a device having a function as an interface with the public PHS network 5. That is, the private branch exchange 1 sends the mobile terminal 3
When a location registration request is received, a location registration request is made to the public PHS network 5 and the public PHS
A function for creating a table showing the relationship between telephone numbers in the network 5 and extension numbers in the private PHS area 100, and, when a call request for the mobile terminal 3 is received from the private branch exchange 1, calls are made to the public PHS network 5. And if there is an incoming call to the mobile terminal 3 from the public PHS network 5,
It has a function of extracting an extension number based on the table and performing incoming call processing to the private branch exchange 1 using this extension number. <Operation> Hereinafter, the operation of this specific example will be described.
1. 1. location registration operation; 2. Calling operation; The incoming operation will be described step by step. 1. Operation at the time of location registration Generally, mobile terminal 3 registered in public PHS network 5
Performs a location registration operation when it enters the service area. Therefore, when the mobile terminal 3 registered in the public PHS network 5 enters the self-owned PHS area 100, the mobile terminal 3 similarly performs a location registration operation. FIG. 2 is a flowchart at the time of location registration. First, the mobile terminal 3 performs a location registration operation by assigning a predetermined routing number (step S1).
As described above, since the private branch exchange 1 is pre-defined to connect to the public PHS network connection device 4 in the case of information including a predetermined routing number, the private branch exchange 1 sends this location registration operation to the public PHS network connection device 4. A connection is made as a call originating operation (step S2). As a result, the public PHS network connection device 4 performs a location registration operation of the mobile terminal 3 with respect to the public PHS network 5 (step S3). For example, the routing number of the private branch exchange 1 to the public PHS network connection device 4 is “0”, the location registration request information for the public PHS network connection device 4 is “1”, and the telephone of the mobile terminal 3 in the public PHS network 5 The number is "050123
Assuming that the extension number in the private PHS area 100 is “890”, the information transmitted from the mobile terminal 3 at the time of location registration is “0 + 1 + 05012345667 + 8”.
In this way, when performing the location registration operation, the private branch exchange 1 does not have the function of performing the location registration processing of the public PHS network 5, and therefore performs the processing operation in the public PHS network connection device 4. "0 + 1 +" as described above.
When information such as "05012345667 + 890" is sent from the mobile terminal 3, the private branch exchange 1 routes the call to the public PHS network connection device 4 with the routing number "0", thereby connecting to the public PHS network. The device 4
Upon receiving the additional information of location registration ("1"), the public PH
The location registration is executed for the S network 5. At the same time, the telephone number of the public PHS of the mobile terminal 3 (“05012345”)
67 ”) and the extension number (“ 8
90 ") (step S4). [Effects at Location Registration] As described above, if only the routing number of the public PHS network connection device 4 is defined for the private branch exchange 1, the public is required. Even in the private branch exchange 1 which does not support the location registration processing with the PHS network 5, the private exchange 1 is connected to the public PHS network without being conscious of executing the location registration processing of the mobile terminal 3 to the public PHS network 5. By performing a normal PBX transmission operation to the device 4, it becomes possible to register the position from the self-owned PHS area 100 to the public PHS network 5. [0021] 2. The public PHS network 5 which has completed the transmission operation position registration. The mobile terminal 3 registered in the mobile terminal 3 can perform a calling operation to the public PHS network 5. The mobile terminal 3 can make a call to the public PHS network 5, that is,
The telephone number “050123456” in the public PHS network 5
When a call is to be made from a 7 "standpoint, the private branch exchange 1 does not support a call processing operation with the public PHS network 5, so that the processing operation is left to the public PHS network connection device 4. The outgoing call from the terminal 3 to the public PHS network 5 is transmitted to the private branch exchange 1 by the public PHS network connection device 4.
Route as outgoing operation to. FIG. 3 is a flowchart of the transmission operation. When the mobile terminal 3 originates a call as a telephone terminal in the public PHS network 5, the mobile terminal 3 sends the private branch exchange 1 a routing number to the public PHS network connection device 4,
The destination telephone number is transmitted as additional information (step S1). For example, if the routing number of the private branch exchange 1 to the public PHS network connection device 4 is "0" and the telephone number of the called party is "012345789", the information sent from the mobile terminal 3 at the time of calling is "0 + 01234678".
Thus, the private branch exchange 1 recognizes only the routing number (= "0") to the public PHS network connection device 4 and performs a calling operation (steps S2 and S3). The public PHS network connection device 4 transmitted from the exchange 1 directly transmits the destination telephone number from the mobile terminal 3 to the public PHS network 5 (step S4), whereas the private branch exchange 1 transmits the call from the mobile terminal 3. If the routing information is not included in the information (step S2)
Performs normal extension transmission processing and transmission processing to the general public network (step S5). That is, the user of the mobile terminal 3 has a public PHS
If a call is to be made from the standpoint of the network 5, a routing number "0" is added and the destination telephone number is dialed. If a call such as an extension call is made, the destination telephone number is dialed as it is. [Effects of Calling Operation] As described above, if only the routing number to the public PHS network connection device 4 is defined for the private branch exchange 1, the calling process with the public PHS network 5 is not supported. The private branch exchange 1 also performs a normal PBX transmission operation to the public PHS network connection device 4 without being aware that the mobile terminal 3 performs transmission processing to the public PHS network 5 in particular. Transmission from 100 to the public PHS network 5 becomes possible.
In addition, only one mobile terminal 3 can make a call to an extension in the private PHS area 100 and a call to the public PHS network 5 only by defining a routing number. 3. The mobile terminal 3 registered in the public PHS network 5 that has completed the receiving operation position registration can perform the receiving operation from the public PHS network 5. The mobile terminal 3 receives an incoming call from the public PHS network 5, ie,
The telephone number “050123456” in the public PHS network 5
7 ", the private branch exchange 1 does not support the incoming call processing operation with the public PHS network 5, so that the processing operation is entrusted to the public PHS network connection device 4. Is a flowchart of an incoming call operation.
When there is an incoming call from the public PHS network 5 to the mobile terminal 3 in the private PHS area 100, the public PHS network connection device 4
First, referring to the correspondence table between the telephone number of the public PHS and the extension number of the private PHS created at the time of location registration,
Self-employed P for S's phone number "0501234567"
It is converted to the HS extension number “890” and transmitted to the private branch exchange 1 (steps S1 and S2). As a result, the private branch exchange 1 performs connection processing assuming that there is an incoming call at the normal mobile terminal 3 extension (step S3). In addition, the public PHS network connection device 4 notifies that there is an incoming call from the public PHS network 5 as additional information. Based on the additional information, the mobile terminal 3 identifies the incoming call from the public PHS network 5 instead of the normal incoming call (step S4). [Effects of Incoming Call Operation] As described above, also in the incoming call operation, the public PHS network connection device 4
By providing a correspondence table between the telephone number of the S network 5 and the extension number of the private PHS area 100, the public PHS network 5
Even if the private branch exchange 1 does not support the incoming call processing from the public PHS network 5, the private branch exchange 1 that does not support the incoming call processing from the public PHS network 5 to the mobile terminal 3 does not perform the incoming call processing. By carrying out, the incoming call from the public PHS network 5 to the self-owned PHS area 100 becomes possible. Also, since the PHS network connection device 4 notifies the private branch exchange 1 of an incoming call from the public PHS network 5, the private branch exchange 1 only needs to handle the extension incoming call. On the mobile terminal 3 side, it is possible to recognize from the additional information that the incoming call is from the public PHS network 5. << Usage Form >> In the above specific example, the mobile terminal 3 existing in the private PHS area 100 accommodated in the private branch exchange 1 performs location registration to the public PHS network 5, outgoing call, and incoming call from the public PHS network 5. Although it has been described that the private branch exchange 1 can be realized by the normal transmission / reception operation of the private branch exchange 1 without being conscious of the private exchange 1, the same operation uses not only the transmission / reception but also the special number provided by the communication carrier of the public PHS. A service (a service corresponding to the number by dialing a predetermined number can be received) can also be realized in the self-owned PHS area 100. In the above specific example, the specific public service network is the public PHS network 5 and the predetermined area is the private PHS network.
Although the S area 100 and the mobile terminal 3 have been described as PHS telephone terminals, any system other than the PHS may be used as long as the local cordless system has such a configuration. In the specific example, the routing number is “0” and the location registration request information for the public PHS network connection device 4 is “1”. However, the present invention is not limited to these numbers, and any number can be selected. is there.
