Embodiment 1

[0045] figure 1 Represents a telephone exchange system based on a program-controlled exchange of the present invention. It includes a program-controlled exchange, an outside line, and a plurality of terminals, respectively the first terminal, the second terminal, ..., the Nth terminal. The telephone exchange system in this embodiment does not include the traditional extensions that need to be connected through telephone lines. , so the telephone call from the switchboard to multiple terminals can be realized without wiring connection. in:

[0046] The program-controlled exchange includes: a computer, an external line connection module and an internal line connection module. The computer includes a central processing unit (CPU) and a memory (RAM). A connection module, wherein the wireless connection module is a wireless transceiver device with a Wi-Fi function. The outside line connection module includes an analog user interface and an analog repeater, or includes a digital ...

Embodiment 2

[0067] see image 3 , a telephone exchange system based on a program-controlled exchange described in the second embodiment, its composition is roughly the same as that of the first embodiment, the difference is that the telephone exchange system of the second embodiment includes two wireless terminals, It also includes three ordinary fixed telephones, that is, extensions that need to be connected through telephone wires, namely the first extension, the second extension and the third extension. These three extensions are all connected to the extension connection module through telephone lines, and the corresponding extension numbers are 603, 604 and 605 respectively. Among them, the corresponding relationship between the extension and its extension number is shown in Table 2, as follows:

Embodiment 3

[0074] A telephone exchange system based on a program-controlled exchange described in the third embodiment has roughly the same composition as that in the first embodiment, except that the wireless connection module in the third embodiment is a wireless transceiver device with integrated bluetooth functions. The first terminal is a smart phone with a bluetooth interface, the second terminal is a tablet computer with a bluetooth interface, and the tablet computer also has voice call and dialing functions, and the Nth terminal is a smart phone with a bluetooth interface. In the third embodiment, the command and data transmission between the program-controlled exchange and the first terminal, the second terminal, . . . , the Nth terminal is completed through the Bluetooth connection.

[0075] Among them, taking the first terminal as an example, there is a control program on the first terminal that enables the first terminal to realize the extension function. The control program h...

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...
