BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for adjusting a volume of a radiotelephone, and more particularly to a volume automatic adjustment method capable of automatically adjusting a reception volume of a mobile station of a radiotelephone regardless of the place of use.

In general, a wireless telephone is composed of a fixed station connected to a telephone communication line and receiving a signal primarily, and a mobile station that a user can move and use in a separate place from the fixed station. Among them, the mobile station of the wireless telephone has gradually developed into the trend of small size and light weight, making it easier for users to carry. In particular, with the recent development of communication technology, the technology of analog cordless telephones has been digitalized, so that mobile telephones can be used from home to office or wireless public telephone service in public places, thereby making it easier to carry mobile stations.

However, as described above, the mobile station is more convenient to carry, but the volume control in the radiotelephone is virtually impossible to control the volume of the system in consideration of the environment of the system and the surrounding environment depending on the input of the volume control key of the user. If the field used is limited to home use only or under a specific environment, the change to the surrounding environment does not have a big difference in time, so the need for volume control may not be felt.

However, as handsets of cordless telephones are used in various environments such as home bases, office bases, and public bases, appropriate volume control is required according to the base system in which volume control of digital cordless telephones is used.

It is therefore an object of the present invention to provide a method capable of automatically controlling the reception volume level of a mobile station of a radiotelephone.

Another object of the present invention is to provide an automatic receiving volume control method by which the user does not need to adjust the receiving volume level by automatically fixing the volume according to the surrounding environment of the apparatus to be used so as to have a volume suitable for the system to be used. will be.

In order to achieve the above object, the present invention provides a digital wireless telephone that sets a mode of a base to be connected for a call, forms a channel, and transmits corresponding system information.

Setting a level corresponding to the selected system according to selection information of a system among the transmitted information; Adjusting the level made in the setting step according to the control of the volume key after the setting step; And a step of storing a volume level made in the adjusting step. And

If the selection of the base mode after the initialization process is characterized in that it comprises the step of automatically adjusting the volume level of the radio telephone by reading the level for the base mode of the volume level stored in the storage step.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a general volume control method used in a conventional volume control apparatus.

As described above, mobile stations of digital cordless telephones have two modes, home mode and public mode, which can be registered and used in multiple home bases and multiple public bases. To do this, you must find the base mode you want to talk to. Also, if you register to multiple bases in the mode, you need to find a system that matches your base.

That is, the initial operation for the call in the wireless telephone is to select the corresponding system (step S100). Wireless telephones generally have a system selection key to facilitate this selection. Using this system selection key, the user selects the desired base.

When the base is selected, the channel is set up by off-hook to set up a link by transmitting information of a desired system (step S110). In this case, handset ID and base ID are transmitted among the information shown in Table 1 below.

The communication with the other party is performed through the above process. At this time, the user controls the volume level using the volume control key installed in the key input unit according to the state of the received signal in order to facilitate the communication through the wireless telephone. That is, it is determined whether the pressed volume key increases or decreases the volume (step S120).

If the volume is to be increased, the level is increased (step S130). On the contrary, if the volume is to be decreased, the level is decreased (step S140). After the operation for the volume operation is finished, the process returns to step S120 to continuously check whether the volume key is controlled.

In the operation of the volume control, the volume level in the home with low noise and the volume level for the noisy public use are generally felt differently to the user, and thus the user needs to control the volume in the above-described manner.

However, the conventional volume control method as described above has an inconvenience in that the user must adjust the volume of the system at every call.

Accordingly, the present invention allows the automatic adjustment of the volume using the configuration shown in FIG. 2, which will be described in more detail with reference to FIGS.

2 is a block diagram of a reception volume level adjusting apparatus for a radiotelephone according to the present invention.

In FIG. 2, 10 is a microprocessor serving as a control unit for controlling the operation of all peripheral circuits, 20 is a ROM incorporating a program for the operation flow in the control unit, and 30 is a temporary processor for storing data during operation. RAM, 40 is a nonvolatile memory for recording and storing system information according to the present invention, such as a registration table, and EEPROM. 50 is a key used as a means for controlling the level of a volume for an interface with a user. As inputs, in particular, it includes a system key to be used as a means for the user to select a home or public system and a volume controller which serves to further control the fixed volume. In addition to these components, a liquid crystal (LCD) 60 may be included to inform the user of the current volume level during volume control. At this time, the contents stored in YPIROM have a system flag that distinguishes the ID of the base system to which the handset is registered and the home or public use described in [Table 1].

The operation of the volume control device having the configuration as described above is the same as in FIG. 1, the process of selecting a system for a call and setting up a link as shown in FIG. 1 (S200-S210). However, in the present invention, after the above process is performed, the state of the selected system is determined by using a system flag among information transmitted as shown in [Table 1] before the user controls the volume (step S230).

If the system is set to the home mode in step S230, the current state is set to the home level (step S240). If the system is set to the public mode, the current state is set to the public level (S250). step).

As described above, after determining the volume level according to the mode selection of the system, it is determined whether the volume key is pressed by the user (step S260). If the pressed key is the volume up key, the level of the volume is increased (step S270). If the pressed key is the volume down key, the level of the volume is decreased (step S280).

When the volume for the level of the mode is determined through the above steps S260 to S280, the volume level is stored in the Y pyrom 40 in the form of a table as shown in [Table 2]. The type of table stored at this time is as follows.

As such, by storing the data in a memory through a separate volume setting process according to each base, the user does not have to control the volume in the same environment in the future.

The above process can be seen as a process for initializing the system, and after the initial setting is made for each system, the process of using it in a specific scene has the flow shown in FIG.

Steps S300 to S340 in the flowchart of FIG. 4 are the same as steps S200 to 250 of the flowchart of FIG. 3, but in FIG. 4, information about the volume level is already set for each system. The process ends without performing steps S260 to S280 of FIG. 3.

That is, when the system is determined according to the system flag in step S320, the volume level set and stored for the system is read from the memory and the volume is controlled to the level.

Therefore, the user can automatically adjust the volume control of the digital radiotelephone that can be used under different environments to the volume suitable for the system environment at the moment of selecting the system. By such automatic adjustment, it is possible to delete the key (up / down key) for volume control in the key input unit as shown in FIG.

In addition, although the mode of the system has been described in the two cases of a home system and a public system so far, this is done in the same way when setting a plurality of systems assuming N number of usable systems as shown in FIG. Can be.

As described above, the present invention can automatically control the reception volume level of the mobile station of the radiotelephone to automatically control the reception volume level in the environment in which the mobile station is used, for example, the home where the noise is low and the reception volume level for the noisy public use. By doing so, the user does not need to adjust the reception volume level separately.
