Stored program control exchange, and radiotelephone call system and method based on stored program control exchange

Abstract

The invention discloses a stored program control exchange, and a radiotelephone call system and a method based on the stored program control exchange. The stored program control exchange and the radiotelephone call system comprise the stored program control exchange, at least one exterior wire and at least a wireless terminal, wherein the stored program control exchange includes a computer, an exterior line linking module and an interior line linking module which is used for connecting a fixed-line telephone; the computer comprises a central processing unit, an memory and the like; the exterior line linking module and the interior line linking module are respectively connected to the computer through a bus; at least one exterior line is connected with the stored program control exchange through the exterior line linking module; a wireless linking module is also arranged inside the stored program control exchange, the wireless linking module is connected with the computer through the bus, at least a wireless terminal is in wireless connection with the wireless linking module. According to the stored program control exchange, the radiotelephone call system and the method based on the same, the stored program control exchange is integrated with wireless transmit-receive devices, terminals with wireless linking functions are regarded as extensions so that the extensions can be increased without arrangement of wires.

Description

technical field

[0001] The invention relates to digital program-controlled exchange technology in the communication field, in particular to a program-controlled exchange, a wireless telephone call system based on the program-controlled exchange and a method thereof. Background technique

[0002] Businesses or families usually need to set up fixed phones. In order to facilitate calling in each office location or room, it is usually necessary to set up multiple extensions in different locations. Existing telephone exchange systems are all extension-switchboard telephone transfer systems based on program-controlled exchanges.

[0003] Generally, enterprises or families apply for at least one fixed-line outside line from the telecommunication service provider, and connect the outside line to a program-controlled exchange (also called a group telephone exchange) inside the enterprise or home. The central processing unit (CPU) performs stored program control and is used to manage...
