Technical field
The present invention relates to a kind of base station transmitting/receiving device, relate in particular to the GSM base station transmitting/receiving device of field of mobile communication.
Background technology
GSM (Global System for Mobile Communications, global system for mobile communications) system is a kind of mobile communication technology standard that originates from Europe, is second generation mobile communication technology.Gsm communication system mainly is made up of mobile switch system MSS (Mobile Switch System), base station sub-system BSS (Base Station Subsystem) and mobile station MS (Mobile Station) three parts.Base transceiver station BTS (Base Transceiver Station) and base station controller BSC (Base StationController) have constituted base station sub-system.
Base transceiver station BTS can regard a radio modem as, is responsible for the reception of movable signal and sends handling.Comprise the needed various hardware and softwares of wireless transmission, as transmitter, receiver, support the needed antenna of various cell structures (as omnidirectional, fan-shaped, starlike and chain), connect interface circuit and the needed detection of sending and receiving stations itself and the control device etc. of base station controller.Interface definition between base transceiver station and the base station controller is the Abis mouth.Traditional base transceiver station and the Abis interface physical layer between the base station controller are used the PCM link of speed as 2048kbit/s, i.e. E1 transmission means.G.703, the physical electrical parameter of physical layer meets CCITT advises, realizes relay transmission by microwave or optical cable.
GSM has successfully covered more than 200 countries and regions at present as the maximum mobile communication network of global scale, has and surpasses 1,800,000,000 cellphone subscriber.According to statistics: for mobile voice service 70% from indoor; From indoor, therefore improve the indoor covering of GSM for mobile data services 60%, improving indoor mobile communication quality is that global mobile operator opens up one of important channel of new user.
Traditional indoor covering solves the schemes that adopt indoor covering systems such as little base station+leaky cable or splitter more.This scheme cost height need carry out special construction construction, and the base station also needs special machine room and transmission.In addition, this solution is generally built by mobile operator is leading, and for the busy enterprise of internal communication, office building, the high of communication fee also is an outstanding contradiction.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of base station transmitting/receiving device, make full use of transfer resources such as existing local area network (LAN), the Internet, interconnected Access Network, data transmission network, save the wiring expense of E1 special line, saved operator's construction and operation cost to greatest extent.
In order to address the above problem, the invention provides a kind of base station transmitting/receiving device, comprise: Network Interface Module, baseband processing module, radio-frequency module and antenna feeder module, wherein, described Network Interface Module, be used for to data finish protocol conversion, data are unpacked, are packed, and externally provide Ethernet interface, it is mutual between the Network Interface Module and the external world to make data pass through this Ethernet interface.
Further, device of the present invention, wherein, and described base station transmitting/receiving device, the Ethernet interface that provides by Network Interface Module is connected with base station controller.
Further, device of the present invention, wherein, described Network Interface Module will treat that mutual data are sent to transmission protocol layer earlier, difference according to business datum adopts protocol stack to handle respectively, be encapsulated into again in the agreement, utilize multiplexing, the cooperation of bag verifying function of agreement to finish transport layer functionality jointly, break into the IP packet again, by the Ethernet transmission, carry out data interaction with base station controller.
Further, device of the present invention, wherein, described Network Interface Module is the Abis interface protocol data by data mutual between described Ethernet interface and the described base station controller.
Further, device of the present invention, wherein, described Network Interface Module, the protocol stack that is adopted are the protocol stack of RUDP or real time transport protocol, described agreement is a User Datagram Protoco (UDP).
Further, device of the present invention, wherein, described baseband processing module is finished the translation function of second and third layer protocol of Um Interface (air interface) to network interface protocols.
Further, device of the present invention, wherein, described base station transmitting/receiving device also comprises power module, is used to receive the input voltage of external power source mouth, and required various power supplys are provided.
Compared with prior art, device of the present invention, traditional E1 interface is substituted with Ethernet interface, be connected with BSC by the IP Abis interface, utilize existing the Internet or the LAN of enterprise to substitute traditional E1 special line transmission,, saved the great number construction cost as far as possible by existing Local Area Network, the Internet, the transfer resources such as networking, data transmission network that connect, for the quick dilatation of operator provides advantage, save operator's construction and operation cost to greatest extent.
