Abstract

PROBLEM TO BE SOLVED: To enable a slave set to take synchronization with other radio base station CS and to conduct communications by providing a common identifier to each CS so as to allow the slave set to be registered to only one CS. SOLUTION: Each of CSs 110-112 is provided with a memory 6 that stores an identifier in common with each CS, a common ID processing means 7 that gives identifier in common to each CS to a slave set 201 at the registration of the slave set and sends the identifier through a control channel, and control section 8 that controls each section. The slave set 201 is provided with a memory 15 that stores the identifier in common to each CS and with a common ID processing means 16 that identifies the identifier sent through the control channel from the CS 110-112. Then the slave set establishes synchronization with each CS by having to register only a single CS and discriminates a communication-enabled CS with the identifier in common for each CS to make communication.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a private branch exchange (PB)
The present invention relates to a digital radio telephone apparatus for transmitting and receiving a radio signal between a radio base station connected to X) and a slave unit.

[0002]

2. Description of the Related Art In recent years, radio telephone apparatuses have been widely used with their convenience and economy being improved. Among them, a digital radio telephone apparatus for communicating an analog signal with a digital signal is described below as a conventional example. explain.

FIG. 4 is a block diagram showing a configuration of a conventional digital radio telephone device. Reference numeral 100 denotes a radio base station (hereinafter, referred to as CS) of the digital radio telephone apparatus. In the radio base station (CS) 100, 1 is a radio unit for performing radio communication, 2 is an antenna, and 3 is for communication with a PBX. PBX
An interface unit 4, a memory for storing a CS identifier and the like, and a control unit 5 for controlling each of the above units.

Reference numeral 200 denotes a slave unit of the digital radio telephone apparatus. In the slave unit 200, 11 is a radio unit, 12 is an antenna, 14 is a memory for storing CS information, and 13 is a control unit for controlling each unit. . Reference numeral 300 denotes a PBX to which the CS 100 is connected. CSs 101 and 102 are connected to the PBX 300, respectively.
The same operation as 0 is performed.

[0005] The operation of the digital radio telephone apparatus configured as described above will be briefly described below.

The user of the digital wireless telephone device is
When a call is made via the CS 100 using 00, registration processing for registering the child device 200 so that it can communicate with the CS 100 is first performed.

[0007] The registration process is first performed by the PBX 300 through the CS.
A message is sent to the control unit 5 via the PBX interface unit 100 requesting that the slave unit registration be accepted. The control unit 5 of the CS 100 sends information indicating that registration is being accepted on the control channel to the child device 200 via the wireless unit 1.

The handset 200 in the standby state is
When the synchronization is established between the slave unit 200 and the CS 100, the information indicating that the CS 100 is in the registration accepting state issued on the control channel is received, and the control of the slave unit 200 is performed. The unit 13 sends a message requesting registration to the CS 100. The control unit 5 of the CS 100 that has received the message sends the registration request message to the PBX 300.

When registration is completed in PBX 300,
A registration completion message is sent from PBX 300 to CS 100. CS 100 transmits this message to handset 200. The handset 200 receives the message,
The identifier unique to S (CS100) is stored in the memory 14, and the registration is completed.

When the slave 200 calls another slave or an outside line, the following processing is performed. Slave unit 200
Synchronizes with the CS 100 and receives information transmitted from the control channel of the CS 100. The control unit 13 of the child device 200 extracts the CS-specific identifier included in the received information and compares it with the CS identifier stored in the memory 14. If the identifiers match, the control unit 13
It is determined that wireless communication may be performed with respect to S100, and CS
A call request message is transmitted to 100. The control unit 5 of the CS 100 having received the message sends the call request message to the PBX 300.

When a call is accepted in PBX 300, a call acceptance message is sent from PBX 300 to control unit 5. The control unit 5 of the CS 100 transmits this message to the child device 200. With the above processing, the child device 200
Make a call via the CS 100.

Also, when the slave unit 200 performs a call via another CS connected to the PBX 300, that is, the CS 101 or CS 102, the registration operation with the CS 101 or CS 102 is performed in the same manner as the operation for performing the call via the CS 100 described above. Then, each CS-specific identifier is stored in the memory 14 and compared with the CS-specific identifier included in the information on the control channel transmitted by each CS to establish a call.

[0013]

However, the conventional C
In the method of establishing communication with S, when the number of CSs is large, and when the slave unit is configured to store an identifier unique to the CS, the slave unit requires a large amount of memory, which is difficult.
It also takes time to check whether the identifier received from the CS matches the identifier stored in the memory. In addition, there is a problem that registration has to be performed many times with each CS, which is very troublesome.

The present invention has been made in view of the above-described problems, and has the following features.
It is an object of the present invention to provide a digital radio telephone device which can establish synchronization with each CS by registering each time and make a telephone call.

[0015]

In order to solve this problem, the present invention sets an identifier common to each CS, and provides a common ID processing means and a memory for storing the common identifier in the CS. , A common ID processing means, and a memory for storing a common identifier are provided. In the slave, each CS common identifier sent from the CS at the time of registration of the slave is stored.
Notifies the common identifier on the control channel, so that the slave unit determines that the CS is communicable with the common identifier, and performs control to establish communication.

According to the present invention, it is possible to provide a digital radio telephone device which enables a slave unit to establish synchronization with each CS by one registration and to make a call.
