Abstract

PROBLEM TO BE SOLVED: To provide a cordless communication unit that can quickly find out a master unit making registration of a slave unit among a plurality of master units and to provide its control method and a storage medium. SOLUTION: A master unit whose mode changes to a slave unit registration mode writes a code '0101' denoting that the master unit is a master unit executing subscriber writing to an extended call service area of a call signal and transmits the resulting call signal. Upon the receipt of the call signal sent from the master unit, a slave unit whose mode is changed to the registration mode discriminates whether or not the code '0101' is written in the extended call service area so as to discriminate whether or not the master unit is the subscriber write performance master unit.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base unit connected to a communication network, and a plurality of information channels connected to the device connected to the communication network via the base unit by wireless communication with the base unit. The present invention relates to a cordless communication device including a slave device capable of performing communication using the same, a control method thereof, and a storage medium.

[0002]

2. Description of the Related Art Simplified mobile phones (PHS: Personal H)
andyphone System) selectively receives control signals from public base stations and private base stations and establishes synchronization with the control signals.
After that, it shifts to the standby state.

[0003] The control signal includes a control channel (CCH: Cont).
The control channel is mainly composed of the following three types of channels. (1) BCCH (Broadcasting Control Channel) The BCCH is a broadcast channel through which various pieces of information necessary for the slave unit to start communication are transmitted.
Radio channel information notification message for notifying the structure of the radio channel, such as what timing the receiver should be operated, system information notification message for notifying congestion regulation information, etc., second system for notifying country code, system type, etc. An information notification message and the like are transmitted. By obtaining this information, the slave unit can know which base unit is within range and at what timing a signal for starting communication should be transmitted.

FIG. 5 shows an example of a format of a system information notification message. (2) SCCH (Standalone Control Channel) The SCCH is a channel for notifying notification of a communication time slot. (3) PCH (Paging Channel) The PCH is a channel for transmitting a call signal transmitted from the parent device to the child device when the child device receives an incoming call.

FIG. 6 is a diagram showing an example of a format of a call signal.

[0006] An aggregate obtained by combining 12 of these channels is called a superframe. For example, as shown in FIG. 7, the slave unit receives the superframe, and the radio of the BCCH always located at the head of the superframe. The channel information broadcast message is received, and the reception timing of a signal from the parent device is determined.

Normally, when registering an extension of a PHS terminal, each terminal has its own identification code (ID) in order to make the master terminal and the PHS terminal the master unit and the slave unit in the same system. Since it is necessary to know, in each of the built-in storage devices, the slave unit PS-ID of the PHS terminal to be registered as an extension slave unit if it is a master unit, and the master unit terminal registered as an extension slave unit if it is a slave unit The operation of writing the parent device CS-ID must be performed. A method of registering a slave unit in a master unit in a PHS terminal is described in, for example, FIG.
And a method as shown in FIG.

[0008] Referring to the sequence diagram of FIG. 9, the “registration start command” is issued almost simultaneously at the parent device and the child device, for example, by turning on the power while pressing the reset button provided on the display and input device. To make a transition to the “registration mode”.

[0009] The parent device that has transitioned to the registration mode further includes:
A slave extension number (here, "11") is input, and a personal identification number (here, "1234") is input, and a system information notification signal (FIG. 5) which is one of the control signals is input. "Subscriber data write execution C" of "CS information"
Transmit with the "S station bit" enabled.

FIG. 8 is a flowchart showing the procedure of a conventional registration process on the slave unit side.

In FIG. 1, the slave unit that has shifted to the registration mode (step S21) first receives control signals from all receivable master units (step S22).

Next, the received signal is analyzed and "CS-I
D ”and“ received electric field strength ”are stored (step S2).
3). For example, when the child device stores the "CD-ID" and "reception electric field strength" of the five parent devices (step S24), the CS-ID of the parent device having the maximum reception electric field intensity is selected (step S25). Then, the base station receives the wireless channel information notification message from the base unit and determines the superframe reception timing (step S26).

When the system information notification signal (FIG. 5) is received (step S27), "Subscriber data write execution C"
It is determined whether or not the S station bit is valid (step S28).

If the subscriber station is not the subscriber station for writing the subscriber data, the data of the master unit of the selected CS-ID is discarded (step S29). Selected (step S25), and again
Receiving the wireless channel information broadcast message of the master unit, and determining the superframe reception timing (step S
26).

[0015] If the station is a subscriber station for performing subscriber data writing, a registration sequence is started (step S30). That is, the same numerical values as the “child extension number” and the “password” input to the parent device in the registration mode are input from the display and input device. Then, in the subscriber data writing sequence processing, after confirming that the “extension number” and “password” entered on the master unit and the slave unit match each other, registration processing is performed, and the child unit is transferred to the master unit. Registration of the device is completed (step S31).

[0016]

However, the above-described conventional cordless telephone has the following problems at the time of registration of a slave unit.

That is, conventionally, the slave unit that performs the registration process is:
Receives the system information broadcast message from the parent device, and determines whether the parent device is performing the registration process by checking whether the “CS information bit” of the “CS information” in the message is valid. Was.

Here, as shown in FIG. 10, for example, there are a plurality of master units A to D near the slave unit a to be registered, and the slave unit a in the registration mode has the registration mode. Assume that the strength of radio wave reception from master unit A is higher than master unit B.

In this case, since the slave unit a makes a state transition based on the flowchart of FIG. 8 from the master unit A having strong radio wave reception intensity, it is determined that the master unit A is not in the registration mode. 1) receiving the wireless information notification message,
(2) After 1.2 seconds, the system information broadcast message is received, and the subscriber data write execution CS is confirmed.
It took as long as 1.2 seconds.
