A method for expanding the operation function of fixed-line communication equipment and fixed-line equipment

Abstract

The invention discloses a method for expanding a fixed telephone communication device operation functions and a fixed telephone device. The method for expanding a fixed telephone communication device operation functions and the fixed telephone device are applied to the communication technology field. An Android program module is arranged in the fixed telephone communication device, wherein the Android program module comprises a plurality of service threads corresponding to the operation functions. The method comprises the following steps: after event information sent by a public switched telephone network PSTN module is received by a serial port driving interface which is obtained through the service threads, a corresponding operation interface is shown according to the event information; or after operation information input by a user is received by any operation interface, the operation information is converted into a corresponding operation code through a preset communication protocol, and the converted operation code is sent to the PSTN module through the serial driving port and the realization of a corresponding event function is driven. The method and the device provided by the invention are characterized in that a fixed telephone is enabled to be provided with a visualized operation interface, and the fixed telephone is improved in capability of interacting with the user.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for extending the operation function of fixed-line communication equipment and the fixed-line equipment. Background technique [0002] Existing fixed telephones use PSTN (PublicSwitchedTelephoneNetwork, Public Switched Telephone Network), and the working principle of PSTN is: [0003] What PSTN provides is an analog proprietary channel, and the channels are connected through several telephone exchanges. When two hosts or routers need to be connected through the PSTN, a modem (Modem) must be used on the network access side (that is, the user loop side) at both ends to realize the analog / digital and digital / analog conversion of the signal. From the perspective of the OSI seven-layer model, PSTN can be regarded as a simple extension of the physical layer, and does not provide users with services such as flow control and error control. Moreover, since PSTN is a circu...
