Description

Wire-wireless hybrid call processing second generation private wireless exchange system and method thereof

The present invention relates to a second generation private wireless switching system (CT-2 type: second generation cordless telephone) system and method thereof capable of call-wireless hybrid type, and in particular, a program can be modified with minimal modification and additional communication between wired and wireless terminals. The present invention relates to a call-processable CT-2 type cordless telephone system of a wired / wireless hybrid type and a method thereof.

A wireless telephone system, which is a kind of mobile communication device, is generally composed of a fixed device and a portable device, and performs wired communication between the fixed device and the exchange period, and wireless communication between the fixed device and the portable device. Therefore, the fixing device must be fixedly installed at a certain position, but the mobile device can be moved to any position where wireless communication with the fixing device is possible, and a wireless link is established by a call between the fixing device and the mobile device. This is possible.

A CT-2 type cordless telephone is a second-generation on-premises cordless telephone that is a kind of cordless telephone mainly used in Europe. While a general cordless telephone communicates with an analog signal, a CT-2 cordless telephone is a digital signal. It communicates, and has a limited frequency compared to a general wireless telephone, and is free to transmit, but only to a certain range.

When the first phone outputs a call signal for calling a second terminal that the first terminal wants to communicate with, the second terminal requested for communication by the first terminal responds to an incoming signal received by the first terminal and the second terminal. Communication is made between terminals.

The call processing technique, which is performed for communication, is different from a wired private exchange and a wireless private exchange. The following describes a call processing technique of a conventional wired private exchange and a call processing technique of a wireless private exchange. do.

First, the call processing technique of the wired private exchange is composed of a structure in which the services of all subscribers are controlled according to a predetermined state and type, and the state and type are determined by the user's operation to call signals. It will either print or receive a call from another user. For example, in the case of an incoming signal, the state when the phone is lifted is off-hook and the type is determined by the extension, and the corresponding program is called.In the called program, the function is performed according to the delivered state and type. Deliver the message to the next established state. That is, each program module is structured to perform functions according to the current state and type, and to perform transition and message transfer to the next state.

In addition, the call processing technique of the wireless private exchange uses a technique in which a program operates with a state transition similar to that of a wired private exchange, but a wireless communication program is configured for a location registration or handover function, which is a special function of the wireless private exchange. have. In other words, the message coming from the wireless terminal is structured to analyze various messages and deliver them to the corresponding program.

The conventional call processing scheme described above has a one-to-one message structure in the wired private exchange call processing scheme, and thus cannot be operated when a broadcast (multiple identical messages) is received. It is. That is, the function of the wireless terminal cannot be implemented. For example, when a wireless terminal wants to make a call, since the first off-hook message is input to the call processing program as a broadcasting message, several off-hook messages are inputted to one (1) terminal and do not operate.

In addition, in the conventional wireless switch call processing technique, there are many difficulties when trying to add a special function such as a wired switch. For example, in order to implement the function of call switching, the wireless switch call processing technique needs to process a variety of wireless messages and implement a program similar to the call switching implemented in the wired function to enable the function of call switching. In other words, special features can only be implemented with a lot of time and effort.

Accordingly, in order to compensate for the above disadvantages, in the present invention, the second generation private wireless exchange (CT-2) capable of performing wired / wireless hybrid type call processing by allowing the communication between wired and wireless terminals to be modified and added to the minimum. Type: To provide cordless telephone type 2) system and method thereof.
