Description
Technical field
The present invention relates to electronic device field, particularly relate to a kind of wireless communication system supporting multi-communication standard to access and method.
Background technology
China telecommunication is through development long-term for many years, 2G/3G/4G the situation deposited are gradually formed, mobile communication signal transmission is all transmitted by certain frequency, and the frequency that three big operators have and network formats are not quite similar, in the market in the standard used respectively:
China Mobile: GSM800, GSM1800, TD-SCDMA, TD-LTE;
CHINAUNICOM: GSM800, GSM1800, WCDMA, TD-LTE, FDD-LTE;
China Telecom: CDMA, CDMA2000, TD-LTE, FDD-LTE.
Above-mentioned also do not include the excessive standard that each generation communication technology produces in speech process, thus it is not difficult to find out that china telecommunication standard just under arms is many, each operator differs based on the frequency used under various communication standards is just more numerous and diverse, the arrangement and method for construction that this communication present situation makes signal cover is complicated, and difficulty of construction is big, easily form coverage hole and ping-pong, cover difficulty and cost that signal optimizes after also increasing, cause public resource to waste.
In this case, multi-service compartment system (MultiserviceDistributedAccessSystemSolution, MDAS) arise at the historic moment, MDAS adopts netting twine/optical fiber as transmission medium, support Duo Jia operator, support multi-standard, multicarrier, and integrated WLAN (WirelessLAN, WLAN) system, one step solves voice and data traffic requirement, improve the accuracy that signal covers, it is greatly reduced signal and covers the complexity of engineering and the difficulty of construction maintenance, compared with traditional analog compartment system, it is provided simultaneously with mixed networking, delay compensation, automatic carrier track, make an uproar the feature such as low in the up end.
MDAS is mainly made up of access unit (MAU/MU), expanding element (MEU/EU) and far-end unit (MRU/RU).
MDAS basic functional principle is as follows:
Downlink (base station > user): signal is carried out digital processing after the signal of base station/RRU is linked into system and is packed into digital signal by MU, converts digital signals into optical signals fiber-optic transfer to EU again through opto-electronic conversion; The signal that MU is come by fiber-optic transfer is processed by EU, again through fiber-optic transfer to RU; RU is covered away by antenna, is transferred to user after being amplified by the EU signal processing transmitted.
Up-link (user > base station): after the information that user sends out is received by RU, signal is processed again by fiber-optic transfer to EU by RU; The signal that all RU transmit is digitized processing after packing and forms optical signal by opto-electronic conversion by EU, then by fiber-optic transfer to MU; The digital signal of EU is packed after reduction by MU, is transferred to base station/RRU.
Nowadays the most basic structure of the multi-service optical fiber distribution system that is currently in use on market forms as shown in Figure 1, but this basic structure cannot meet the application demand of reality, and waste resource, thus derived following several concentration networking mode used in practical application scene by the system basic structure of multi-service optical fiber distribution system:
1) star-like networking (as shown in Figure 2);
2) chrysanthemum type networking (as shown in Figure 3);
3) mixed type networking (as shown in Figure 4).
The essence of the 3 kinds of networking modes being made up of basic structure is to utilize the extended capability of EU, and EU supports that the extension of RU is thus realizing star-like networking mode; EU supports that the expansion cascading to EU is thus realizing chrysanthemum type networking mode; Two kinds of extended capability set use thus realizing mixed networking mode.
The standard that the multi-service optical fiber distribution system of above-mentioned three kinds of networking modes is supported and frequency range determine by a main access unit (MU), when MU only supports the standard of China Mobile 2G/3G/4G and frequency range, no matter the multi-service optical fiber distribution system of which kind of networking mode also can only cover and process the communication service of China Mobile. It is accomplished by replacing whole multi-service optical fiber distribution system if desired for the business demand supporting other operators, including MU, EU and RU, or installs the multi-service optical fiber distribution system of a whole set of standard supporting other operators and frequency range again additional. Such as: on the former basis having covered China Mobile's signal, extend UNICOM cover with telecommunication signal, be accomplished by:
Adding the optical fiber distribution system of standard and the frequency range supporting UNICOM and telecommunications more respectively in order to cover respective signal, so realize full signal covering and just need to amount to 3 unjacketed optical fiber compartment systems, system rectification schematic diagram is as shown in Figure 5.
Above-mentioned implementation needs to arrange the compartment system that two sets are above, it is achieved the whole network covers all to be needed again or repeatedly wholly-owned input, covers quantities and also will be multiplied, causes the wasting of resources.
Visible, the region using existing multi-service optical fiber distribution system to cover is carried out the standard extension multiple access to realize different location information source, quantities and cost can be multiplied, original serious waste of resources.
