2. Description of the Related Art In a portable telephone apparatus comprising a master unit connected to a telephone line and one or more slave units, an external call through the master unit of the slave unit and a call between the slave unit and the master unit and the slave unit. When making an extension call, it is necessary to form a communication path by calling the called side from the calling side and setting the channel of the wireless line. For example, the first edition of the second generation cordless telephone system standard (RCR STD-2)
8, the portable telephone device conforming to the Radio System Development Center) receives the control data periodically transmitted from the parent device at predetermined time intervals and receives the received control data. The identification code of the master unit included in the data is recognized, and it is determined whether or not the own station is registered in the master unit. When the own station is registered, a timing synchronized with the control data is generated. When calling the master unit from the slave unit, a call request is issued to the master unit at the generated timing.

[0003] Further, when a slave is called from the master, the master transmits control data including the identification code of its own station together with the identification code of the calling slave, and the slave transmits the received control data to the self. The identification code of the base unit and the identification code of the own station stored in advance in the station are compared with each other, and when both match, it is determined that a call to the own station is being performed, and in synchronization with the timing of the control data. And respond to the master unit, and call the user with a bell or the like.

Further, when a slave unit directly calls another slave unit, the calling slave unit alternates the transmission and reception time regardless of the control data that the master unit periodically transmits. A predetermined slot to be assigned to the terminal, using one of the data previously allocated to the direct call between the slave units,
The call data including the identification code of the master unit to which the own station is registered, that is, the own station, the slave unit number of the own station, and the slave unit number of the called side are continuously transmitted. In response to this, the called handset receives the call data for a certain period of time, and if the identification code of the base unit registered for use with the own station matches the handset number of the own station, the other handset receives the call data. Detecting that it is being called directly from the machine, calling the user and responding to the calling handset in synchronization with the timing of the call data,
A communication path is formed by establishing synchronization.

[0005] In order to use a slave unit in this way, the identification code of the master unit whose use is registered is required. The identification code of the master unit is stored in a nonvolatile storage medium in the slave unit by performing a predetermined registration operation at the start of use of the slave unit.

[0006] In a typical prior art use registration method for a mobile phone handset, a user sets the handset in a registration mode and inputs an identification code of a base unit to be used and registered using a numeric keypad or the like. The slave unit receives the control data transmitted from the master unit at the predetermined time intervals, and performs use registration when the identification code of the master unit included in the control data matches the input identification code. Recognize that it should be the parent device. As a result, the slave unit makes a use registration request to the master unit at the timing generated in response to the control data from the master unit as described above, and transmits the identification code of the own station when a communication path is formed. Necessary data is exchanged, for example, and stored in each storage medium, and use registration is completed.

[0007]

In the use registration method of the prior art mobile telephone device as described above, in order to enable the user to specify whether or not the control data from the master unit to be registered at the time of use registration, The user needs to input the identification code of the child device written on the warranty card or the like from the numeric keypad or the like as described above, and the operation is complicated.

An object of the present invention is to provide a mobile telephone device that can be improved operability of the handset.

The main unit storage unit stores an identification code of a slave unit that is to be able to make a radio call with the own station, and the control data creation unit responds to an operation on the registration operation unit. It is possible to register the identification code from the slave unit In this case, the slave unit creates control data together with the additional identification code indicating that, and when the parent device is in a registerable state based on the additional identification code of the control data, the slave device changes the identification code of the master device. It is characterized by comprising registration execution means for storing the identification code of the own station stored in the child device storage means to the parent device and storing the identification code stored in the child device storage means in the parent device storage means.

When control data including the identification code of the base unit 1 stored in the slave unit ID storage unit 45 is received, the process proceeds to step S2. In step S2, it is determined from the destination identification code of the control data whether or not the incoming information for the own station is included, and if it is included, the process proceeds to step S3. In step S3, the notifying unit 48 is driven to notify the user. In step S4, it is determined whether or not the user has responded. If not, the process returns to step S1. If so, the process returns to step S5. Move on to In step S5, it is determined whether or not the end state has been reached by the end operation on the handset 2 side and the end operation on the base unit 1, and if the end state has been reached, the process returns to step S1 to receive an incoming call. It goes into a standby state.

If it is determined in step S2 that the incoming call has not been received by the own station, the process proceeds to step S11, where it is determined from the additional identification code in the received control data whether the base unit 1 is in use or not. Sometimes step S1
2, the parent machine status display means 46 displays that the parent machine 1 is in use.
At 3, the main unit 1 displays that it is not in use. When the control data is not received from the base unit 1 in the step S1, and from the steps S12 and S13, the process proceeds to the step S14, the receiving operation is completed, and after waiting for a predetermined standby time, the process returns to the step S1. Control data is received.

As described above, in the portable telephone device according to the present invention, the master unit 1 uses the additional identification code, which is an undefined part of the calling identification code, of the control data from the master unit 1 to register the use registration state of the slave unit 2. The slave unit 2 automatically receives and stores the identification code from the master unit 1 only by setting the slave unit 2 in the use registration state. This makes it possible to reduce complicated input operations from numeric keys or the like, thereby improving operability.

Further, the master unit 1 is identified by the additional identification code.
Indicates whether the parent device 1 is in use, such as whether the external device is making an external call or an internal call with another child device.

[0042]

As described above, according to the portable telephone device of the present invention , when the parent device performs the use registration operation of the child device, if the received identification code from the child device can be registered, the fact is confirmed. The control data created by combining the additional identification code to be displayed with the identification code of the own station is transmitted to the slave unit.

Therefore, registration of use of the slave unit in the master unit to enable use registration of the slave unit is performed by a complicated input operation such as key input of an identification code written on a warranty card or the like by a user. The slave unit automatically receives the identification code transmitted from the master unit and registers it simply by putting the master unit in a registerable state without causing the operability.
