Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cordless telephone.

[0002]

2. Description of the Related Art A cordless telephone is composed of a base unit connected to a telephone network by wire and a mobile unit that is a mobile telephone.
The communication between the master unit and the slave unit is performed by radio waves.
Unlike analog cordless phones, PHS (Personal
In a digital cordless telephone such as a handy phone system, four slots can be used by one base unit in a time-division manner. If one slot is used for a control channel, three slots can be used for a communication channel. The PHS slave is standardized by ARIB-STD28 (the second generation cordless telephone system standard of the radio wave industry). By registering the PHS slave in the PHS master, indoors, the PHS slave can communicate with another phone using a general telephone line, which is a wired telephone network, via the master similarly to an analog cordless phone. In this case, the subscriber of the general telephone line pays the call fee. On the other hand, outdoors, if a contract is made with an organization that provides PHS public services (hereinafter referred to as a business operator), it is possible to communicate with other telephones by wirelessly communicating with a public base station installed outdoors. In this case, a call fee is charged to the subscriber of the used PHS slave.

[0003] In other words, unlike an analog cordless telephone, a PHS slave unit can be used both indoors and outdoors.
It is common to carry one family member at a time, and it is often the case that a plurality of child devices are added to one parent device instead of one set at home, as in a conventional analog telephone. In addition, in the analog system, the number of slave units connected to the master unit is limited to the same manufacturer. However, since a large number of models are commercialized for each company or each manufacturer, one unit is used. The types of slave units to be added to the master unit are also diverse. Therefore, it is necessary to unify the method of registering the child device for each manufacturer or business operator, so that the operation method is easily known to anyone. In addition, the range of radio waves from the base unit may reach a radius of several tens of meters, and it is possible to communicate via the base unit anywhere where radio waves can reach not only inside the house where the base unit is installed but also outdoors. is there.

In order for a cordless telephone handset to make a call via a base unit, it is necessary to register the cordless telephone base unit as a handset. In a cordless telephone, each cordless telephone has an ID code to prevent interference and erroneous connection. PS-ID (Pe
rsonal Station Identification, CS-ID (Cell Station Identificatio)
n, base unit identification code) is assigned,
Both the parent device and the child device confirm this ID code and connect the line.

FIG. 3 shows a slot configuration of a control channel in the PHS to explain the ID code.

Here, R is a ramp time for transient response, S
S is a start symbol, PR is a preamble, UW is a synchronization word, CI is a channel type, CS-ID is a parent device identification code, PS-ID is a child device identification code, and I is an information bit.

[0007] As shown in FIG.
ID and PS-ID are included. The PHS master receives the radio wave transmitted from the slave through the antenna, demodulates the data into baseband digital data, and then transmits the CS-ID of the own station.
And the CS-ID data included in the slot, and determines whether the received channel is addressed to the own station. Similarly, one or more P
By comparing the S-ID with the PS-ID data included in the slot, it is determined whether the S-ID belongs to the slave unit managed by the own station and the other station to be connected. Furthermore, CS-ID and PS-I
If the determination results in D match, the information data (I data) included in the channel is recognized and the line is connected. Therefore, the general telephone line cannot be used via the master unit unless the master unit is registered as a slave unit.

[0008] The registration process of the slave unit is performed by the master unit on the CS-I
Notify the slave unit to register D, and register the PS-ID of the slave unit to be registered.
Is stored. The child device to be registered notifies the registration destination parent device of the PS-ID and stores the CS-ID of the registration destination parent device. After registration, when communicating between the master unit and the slave unit, the CS-
ID and PS-ID are the CS-ID part in the slot, PS
-Insert it into the ID section and send.

[0009] The child unit registration performs a certain series of operations determined for the model of the terminal to be registered.
