Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital wireless communication system, and more particularly to a transfer operation of a digital wireless telephone in a personal handy phone system (hereinafter referred to as PHS).

[0002]

2. Description of the Related Art Conventionally, in a telephone exchange system or the like which accommodates a digital radio telephone, when a digital radio telephone receives an incoming call, the incoming call is transferred to another outside talker without answering the incoming call. Those having a function are known.

In general, this call transfer function sets the call transfer mode by operating the digital radio telephone and further sets the transfer destination telephone number.

[0004]

However, in the above-mentioned conventional example, the incoming call is automatically transferred to the preset transfer destination regardless of who is the caller. There is a problem in that the transfer destination cannot be changed, and when the caller is a specific individual such as an emergency handler, the transfer destination cannot be changed, which gives flexibility.

It is an object of the present invention to provide a digital radio telephone capable of selecting a transfer destination according to a caller and performing transfer in the call transfer function.

[0006]

SUMMARY OF THE INVENTION The present invention provides a digital radio telephone which communicates via a radio line with a radio base station to which a communication line to which a calling number of a caller is sent is connected.
Storage means for presetting and storing a transfer destination for each calling number of the caller, and when receiving a call, the calling number in the received data and the calling number in the storage means are collated and depending on the calling number in the received data. And an incoming call transfer control means for giving an instruction to transfer to another transfer destination.

[0007]

In the present invention, for an incoming call in which the calling number is stored in advance, the call is forwarded to the forwarding destination according to the calling number. Therefore, the forwarding destination can be changed corresponding to the calling number.
A flexible call transfer function can be provided.

EXAMPLE A PHS will be described as an example as a first example of the present invention.

FIG. 1 is a block diagram showing the configuration of a telephone in the PHS of this embodiment.

The telephone 9 of the present embodiment includes a handset 1 for making a call, a voice processing unit 2 for performing compression coding processing and decompression decoding processing of voice data, and a TDMA processing such as frame disassembly / assembly. , A channel CODEC unit 3 that performs error correction processing, scramble processing, and confidential processing of voice data
A modulation / demodulation unit 4 that modulates transmission data and demodulation of reception data, an RF unit 5 that transmits and receives, an antenna 6 that transmits and receives radio waves, a key operation unit 7 that controls various key inputs, and control of each unit. And a control unit 8 for performing.

The control unit 8 also includes a communication control processing means 8a.
A key operation control processing means 8b, an incoming call transfer information registration means 8c, an incoming call transfer information storage means 8d, and an incoming call transfer information collating means 8e.

Then, the communication control processing means 8a uses the PHS.
The layer 1 to layer 3 communication protocol processing is performed, and the key operation control processing unit 8b analyzes various key input information from the key operation unit 7 and performs processing.

Further, when the call forwarding information registration means 8c inputs the forwarding number of the incoming call to the calling number via the key operation portion 7, the call forwarding information storage means 8d stores the call forwarding information as shown in FIG. Register with.

Further, the incoming call transfer information collating means 8e collates the calling number in the received data with the calling number of the incoming call forwarding information storing means 8d, determines the forwarding destination number and carries out the forwarding process.

Note that, in the example shown in FIG. 3, when there is no calling number in the received data (indicated by **** in the figure), N
O. 1 to NO. Other than the calling party number registered in No. 4, "03-5482-6369" is registered as the transfer destination.

FIG. 2 is a block diagram showing a configuration example of a PHS system including the PHS telephone 9 of this embodiment.

In the figure, the main unit 10 accommodates the ISDN line 11 from the ISDN network 12 and performs exchange control. In addition, the main unit 10 has a communication line 1
The wireless base stations 13 and 14 are accommodated via the wireless communication terminals 5 and 16, and the wireless base stations 13 and 14 have PHS telephones 17 and 1, respectively.
8 (telephone 9) is connected.

When the main unit 10 receives a calling number from the ISDN line 11 and the calling number is sent to the received data, the calling number is transmitted to the PHS telephone 1 via the radio base stations 13 and 14.
It is sent to 7 and 18 as received data as it is.

FIG. 4 is a flow chart showing the operation of this embodiment.

An example will be described below in which there is an incoming call from the ISND line 11 and an incoming call is received by the PHS telephone 17 via the main station 10 and the base station 13 by dial-in setting.

First, when the PHS telephone 17 receives a call, P
The wireless line is connected by the communication control processing means 8a in the HS telephone 17. Then, when the call forwarding setting is made at the stage of the layer 3 processing (ST1), the call forwarding information collating means 8e judges whether or not the calling number exists in the received data (ST2).

If the calling number is present in the received data, the process proceeds to ST3, and if the calling number is not present, ST is entered.
Go to 4.

In ST3, the calling number in the received data is collated with the calling number in the incoming call forwarding information storage means 8d, and in ST4, the forwarding number is determined by the registration information as shown in FIG. Here, the calling number "03-3757-636"
For an incoming call with "9", the number "03-3577-1
111 ”.

Then, the communication control processing means 8a sends a transfer destination number "03-3757-1111" and an instruction to transfer the incoming call to the wireless base station 13.

The transfer destination number "03-3757"
-1111 "and the signal of the call transfer instruction are sent to the main device 10 via the wireless base station 13, the main device 10 captures another free ISDN line (ST5),
A call is made to the transfer destination, and these two ISDN lines 11 are connected via the main unit 10 (ST6). In this way, the incoming call is transferred.

Although the above-described first embodiment uses the PHS as an example, it can be applied to a system using another wireless medium in the same manner as the first embodiment.

In the first embodiment, the main unit is the IS.
Although the incoming call is transferred through the main device using two DN lines, if the ISDN network has the incoming call forwarding function of the additional service, even if the ISDN network is made to perform the forwarding operation, the above first It is possible to obtain the same effect as that of the embodiment.

[0028]

As described above, according to the present invention,
There is an effect that the transfer destination can be changed according to the calling party and a flexible system can be provided.
