Description

Telephonic communication system and method of wire / wireless digital telephone.

The present invention relates to a digital wired and wireless telephone, and in particular, to improve a mutual call between wired and wireless, so that simultaneous calls can be made between a mosquito (fixed device) and a magnetic device (mobile device). The present invention relates to a call device and a method of a digital wired / wireless combined telephone using a 40-channel digital 900 MHz band in which internal and internal telephone calls can be made freely.

More specifically, in a wired / wireless integrated digital telephone composed of mosquitoes and porcelain, the mosquito has an automatic receiving function that receives input up to 5 trunk lines and automatically finds and connects an empty line. The digital wired system allows users to make calls through wireless communication between mosquitoes and magnetism, and between themselves and themselves. The present invention relates to a call device and a method of a wireless combined telephone.

Conventional digital wired / wireless combined telephones include a telephone body (also referred to as a "fixing device" or a "mosquito") with a built-in circuit including a keypad and a cordless telephone (also referred to as a "mobile device" or "magnetic"). It is designed to make calls through mosquitoes.

That is, the conventional wired / wireless combined phone is composed of a mosquito and a self, and only one-to-one communication between the mosquito and the self is possible.

The wire / wireless phone of the above-mentioned method is a method in which the mosquitoes or the other magnets are not used even if the number of magnets is large, but the other magnets are not used.

A more detailed description of a conventional wired / wireless combined telephone is as follows.

An analog cordless telephone is a telephone set that allows a user to carry and talk freely within a range of about 20 meters by replacing part of indoor wiring with a wireless circuit among ordinary fixed telephone lines, and a connection device (fixed device) and a wireless phone (mobile device). It consists of.

In the early days, cordless telephones were a simple form of extending the length of a telephone line wirelessly and operated in a double-duplex manner so that reception and transmission could be performed simultaneously like a fixed telephone. Therefore, cordless telephony requires at least two radio channels, each of which must use frequencies that are far enough apart to avoid interference with each other.

Early forms used only two channels (a pair constituted one communication channel), so that only one frequency could be used for transmission and reception. Thus, to minimize interference between adjacent cordless phones, each cordless phone is limited to very low levels and ranges of output.

Nevertheless, being able to talk freely in the house or in the yard has emerged as an advantage and is now very common.

Although models still use a single communication channel, current cordless phones have 10 to 15 channel pairs for use with FM and with minimal interference.

It also adds the ability to select the 10 most used pairs of channels and find the optimal frequency before transmitting the signal.

However, the home cordless telephone set used in the general home is a form in which part of the indoor wiring is replaced with a wireless circuit, as is well known, and the frequency band should also use a sufficiently separated frequency to avoid interference with each other.

Therefore, there is a restriction that only one frequency can be used for transmission and reception, and if the same product is used simultaneously in an adjacent area, there is a high possibility of crosstalk, and even if the adjacent device is operated to make a call to another set of access devices. There were also disadvantages that occur.

In addition, it is not possible to use two cordless telephones which are still close to each other using the same frequency band at the same time.

Accordingly, the present invention has been proposed in order to solve various problems occurring in the conventional wired / wireless combined telephone as described above.

An object of the present invention relates to a digital wired and wireless telephone, and in particular, to improve a mutual call between wired and wireless, so that simultaneous calls can be made between a mosquito (fixed device) and a mobile device (mobile device), and The present invention provides a call device and a method of a digital wired / wireless combined telephone based on a 40-channel digital channel of 900 MHz, which enables self and self-extension and trunk line calls to be made freely.

The present invention for achieving this object,

By adopting the 900 ㎒ digital communication method, the system secures an ideal system by ensuring clean sound quality and stable wireless communication signals without interference in adjacent areas, and expands the mosquito's trunk line capacity by 1 to 5 lines ( It can be expanded up to 100 lines.) Assign a representative number to automatically find an empty line and connect it.

In addition, by increasing the number of self, by implementing a new signal processing method that can talk directly between the mosquito and the self without a mosquito, the CO line can be made free from the mosquito and self as much as the number of lines Make sure

In addition, it is possible to make a direct call between a multi-party call system and an extension line through an external line.
