Abstract
The utility model discloses a device realizing voice business in the circuit switching domain on a WIFI (wireless fidelity) /3G (generation) router, and comprises a USB (universal serial bus) interface unit, a power manage unit, a main controller unit, a Micro SD (secure digital memory card) interface unit, a 3G module unit and a WIFI AP (assembly program) unit. The main controller unit is connected with a wifi unit through a SDIO (secure digital input and output) interface, connected with the Micro SD interface unit through the SDIO interface, and further connected with the 3G module unit through the USB interface unit. A module supporting voice data transmission and reception is added to the initial router, leading a two-way channel for transmitting voice data to be built between the wifi connection of the router and a user's computer. Accordingly, the coding and decoding of the voice data are realized by a computer and users can speak through earphones and microphones insert into the computer.
Description
Technical field
The utility model relates to a kind of wireless router of supporting that 3G network WAN inserts, the 802.11.b/g WLAN is exported, increased support thereon, made the function that the user carries out the speech business of CS territory by the headset that is inserted on the sound card by cooperation with the PC side software to CS territory voice call transfer of data.
Background technology
Along with popularizing of the application of 3G network, 3G wireless Internet access speed is more and more faster, make a plurality of users share 3G network high speed bandwidth and become possibility by wifi 3G router, the SIM card of using generally portable WIFI/3G router can well solve the problem of a plurality of user radio online shared bandwidths after inserting 3G network, but the related service of but being inconvenient to have user's initiation of SIM card and receiving the CS territory.
Summary of the invention
At the deficiency of prior art, goal of the invention of the present utility model is to provide a kind of device of realizing the circuit commutative field speech business on the WIFI/3G router.
A kind of device of on the WIFI/3G router, realizing the circuit commutative field speech business, comprise: usb interface unit, Power Management Unit, Main Control Unit, Micro SD interface unit, 3G modular unit, WIFIAP unit, described main controller unit is connected with the wifi unit by the SDIO interface; Be connected with Micro SD interface unit by the SDIO interface; Be connected with the 3G modular unit by usb interface unit.
The power management of described router part is main, and parts such as the providing of power-supply system, switching function are provided, and are connected with adapter with USB interface, and the externally fed function is provided.It is PC power supply or power supply power supply that USB can discern, and by judging the power supply provider, determines input current, thereby carries out Current Control.Power Management Unit mainly provides 3.3V to the WIFI unit; Provide 1.8V to 3G modular unit and Main Control Unit.
Existing Wifi 3G wireless router generally just for a plurality of users share the 3G bandwidth, does not provide CS territory voice call function, and after SIM card was inserted router, the audio call in CS territory can't carry out like this, and the user who has SIM card can feel inconvenience.For when a plurality of users can share the 3G bandwidth by wifi, make the user who has SIM card can initiate and receive CS territory audio call, the utility model increases the module that the support voice data send and receive on original router, make router and user PC between wifi is connected, set up a duplex channel and transmit speech data, the encoding and decoding of speech data realize that by PC the user converses by earphone and the MIC that inserts on the PC.
The beneficial effects of the utility model and advantage are:
(1) increased authentication mechanism at original 3G router, the owner of SIM card could open CS territory voice call function after logining by password.
(2) data that increased CS territory audio call at original 3G router send and receiver module, transmit speech data in real time.
(3) increased CS territory audio call administrative mechanism at original 3G router, made the user to control the audio call flow process by PC.
(4) software on the PC is responsible for codec functions, and the other side's tone decoding that the 3G router is sent is sent in the earphone, and user's microphone word coding is sent in the 3G router by wifi, finally arrives 3G network.

Embodiment
How further specify the utility model in conjunction with the accompanying drawings realizes:
Shown in the accompanying drawing 1,2, the Power Management Unit of router 2 is main, and the providing of power-supply systems, switching function are provided, and are connected with adapter with USB interface, and the externally fed function is provided.USB can discern still power supply power supply of computer power supply, by judging the power supply provider, determines input current, thereby carries out Current Control.Power Management Unit 2 mainly provides 3.3V to WIFIAP unit 6; 1.8V 3G modular unit 5 and Main Control Unit 3 are provided.
IFI AP unit 6 is to constitute by WIFImac circuit and rf circuit, and the WIFI data are transmitted to Main Control Unit 3 by the mac layer, realize routing function in the master controller side.
As shown in Figure 3, set up server end on the 3G router, server end is responsible for the transmitting-receiving of call state control and speech data.Client has the complete interface of carrying out audio call, comprises dummy keyboard and virtual screen subscriber dialing and shows the other side's number and be connected.
The user who has SIM card at first connects wifi, brings in the logon server end by the computer client then, and server end carries out certification work.
3G router server end can judge when receiving the speech business of CS territory whether the user logins, if not then refuse this calling; If user's login then sends the phase related control information and sends to client before this call through, server end is waited for Client command.Client is received call control information, plays predefined sound notification customer call and arrives, and show information such as the other side's number, and the client can select to answer and disconnect calling by the interface.After server end is received the request of connecting, connect this and call out, and be responsible for coming from the 3G network opposite end data send to client, and the speech data of client is sent to 3G network, what server carried out is data penetration transmission work, data content is not resolved.
Client is to the data decode that sends and send to the computer side sound card and play, and user's microphone talk content is encoded to send to server end and transmit, and has so just set up both sides' communication process.
The foregoing description provides to those of ordinary skills and realizes or use of the present utility model; those of ordinary skills can be under the situation that does not break away from invention thought of the present utility model; the foregoing description is made various modifications or variation; thereby protection range of the present utility model do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
