Abstract
An intelligent fixed-communication network communication device comprises a radio-frequency unit, a modulator/demodulator, a TDMA/TDD (time division multiple access/time division duplexing) processing unit and an ADPCM (adaptive differential pulse code modulation) transmitting unit. The radio frequency unit is used for performing power amplification and high/medium frequency conversion on signals received from a PHS (personal handy-phone system) handset, an emergency call and a monitor terminal and signals processed by the modulator/demodulator to be transmitted to the PHS handset, the emergency call and the monitor terminal, and the modulator/demodulator and the ADPCM transmitting unit are used for performing ADPCM and Gaussian frequency-shift keying modulation on the received signals processed by the radio frequency unit and to-be-transmitted signals processed by the TDMA/TDD processing unit. The intelligent fixed-communication network communication device is capable of freely conveniently realizing communication at any time any place, so that users of the fixed communication network can use various voice functions, such as voice, short messages, games, real-time information searching, positioning, household monitoring, emergency calls and the like, communication expense can be reduced for the users, utilization rate of the fixed communication network can be increased and higher economic benefits and social benefits are generated.
Description
Technical field
The utility model relates to a kind of network communication device, especially relates to a kind of fixed communication intelligent network communicator.
Background technology
Continuous development along with the communication technology; The huge fixed communication network of being formed with stored-program control exchange, fiber-optic communications traffic net and communication support mesh forms, and that Chinese fixed communication network has been accomplished is programme-controlled, the transformation of digitlization, intellectuality, synthesization.Because the shortcoming that cord telephone terminal and ropeless phone terminal are had separately makes the various value-added services that can carry out in mobile communication be difficult to development on the net at fixed communication on the net; More user relies on the communication custom of fixed communication network termination being moved communication terminal to replace. and simultaneously because social economy, technological development, the user's communications requirement develops into multiple speech, data services such as comprising speech, short message, recreation, real time information search, location, distress call, family's monitoring from speech.Present fixed communication network termination is difficult to adapt to the user's communications requirement; The intelligence communication network that progressively improves and carry out the lid whole nation along with operator of China Telecom radio local telephone network is open-minded, and development will be the developing direction of a desirable based on the fixed communication intelligent network communicator of the cordless telephone communication technology and the intelligent network communication technology.
Summary of the invention
The utility model purpose provides a kind of fixed communication intelligent network communicator, freely realizes the hope of communication whenever and wherever possible for the user provides.
To achieve these goals; The technical scheme that the utility model adopted is: fixed communication intelligent network communicator; Comprise radio frequency unit, modulator-demodulator, TDMA/TDD processing unit, ADPCM delivery unit, interface module, said radio frequency unit carries out power amplification and height/medium frequency conversion to signal that receives from PHS hand-held set, distress call device, watch-dog terminal and the signal that after modem processes, will be transmitted to said terminal respectively; The signal that will send after reception signal after said modulator-demodulator and ADPCM delivery unit are handled above-mentioned radio frequency unit respectively and the TDMA/TDD processing unit processes carries out adaptive difference pulse code and the strong control modulation of gaussian frequency shift; Said TDMA/TDD processing unit decomposes carry out time division multiple access through the demodulated received signal, interweaves, encrypts to form the time division multiple access data flow and the signal that will send is carried out chnnel coding; The interface module that said fixed communication intelligent network communicator links to each other with bus is connected to public switched network, to carry out the transmission of bell signal, voice signal, other signal with public switched network.
The utility model can make things convenient for freely realizes the hope of communication whenever and wherever possible, makes the user of fixed communication network also can enjoy multiple speech, data services such as comprising speech, short message, recreation, real time information search, location, family's monitoring, distress call; Can reduce user's communications expense expenditure, improve the utilance of fixed communication network, produce good economic benefit and social benefit.

Fig. 1 is the block diagram of the utility model.
Embodiment
Below through embodiment, and combine accompanying drawing, the technical scheme of the utility model is further specified.
Fig. 1 is the block diagram of the utility model.Can know by Fig. 1; This fixed communication intelligent network communicator; Comprise radio frequency unit, modulator-demodulator, TDMA/TDD processing unit, ADPCM delivery unit, said radio frequency unit carries out power amplification and height/medium frequency conversion to signal that receives from PHS hand-held set, distress call device, watch-dog terminal and the signal that after modem processes, will be transmitted to said terminal respectively; The signal that will send after reception signal after said modulator-demodulator and ADPCM delivery unit are handled above-mentioned radio frequency unit respectively and the TDMA/TDD processing unit processes carries out adaptive difference pulse code and the strong control modulation of gaussian frequency shift; Said TDMA/TDD processing unit decomposes carry out time division multiple access through the demodulated received signal, interweaves, encrypts to form the time division multiple access data flow and the signal that will send is carried out chnnel coding; Said fixed communication intelligent network communicator is connected to public switched network through the interface module that links to each other with bus, to carry out the transmission of bell signal, voice signal, other signal with public switched network.
Its operation principle: when fixed communication network sends bell signal or other signals; The testing circuit of fixed communication intelligent network communicator with bell signal, voice signal or other signal through conversion; Send into central processing unit; After central processing unit is received this signal, send command adapted thereto immediately, make the radiating circuit energized of radio frequency unit get into operating state.Bell signal, voice signal or other signal are transmitted into the terminal through the radiating circuit of radio frequency unit by antenna.The voice signal that fixed communication network transmits is after audio coder & decoder (codec), TDMA/TDD processing unit processes, and the radiating circuit through radio frequency unit is transmitted on the PHS hand-held set by antenna.
That enter into fixed communication intelligent network communicator for the first time when other terminals such as PHS hand-held set, distress call devices and when covering scope; All to register; The register instruction that it sent is after the antenna of fixed communication intelligent network communicator receives; Select to get into the receiving circuit of host terminal radio frequency unit by duplexer; After demodulator and TDMA/TDD processing unit processes, send into the storage that central processing unit carries out log-on message, send relevant information through the intelligent network communication protocol module to intelligence communication network simultaneously, open the information that the terminal transmission of instruction is succeeded in registration to sending notes after registration is accomplished; The signal that this moment, the PHS hand-held set can only connect that fixed communication intelligent network communicator sends, fixed communication network can only be transferred on the fixed communication intelligent network communicator through intelligent network the calling of PHS hand-held set automatically.
