Description
Technical field
The present invention relates to electronic device field more particularly to a kind of wireless communication systems for the multiple access for realizing different location information source
System and method.
Background technology
China telecommunication passes through development long-term for many years, the situation for having gradually formed 2G/3G/4G and having deposited, mobile communication letter
Number transmission is transmitted by certain frequency, and frequency and network formats that three big operators are possessed are not quite similar, at present
It is respectively in the standard used in the market：
China Mobile：GSM800、GSM1800、TD-SCDMA、TD-LTE；
China Unicom：GSM800、GSM1800、WCDMA、TD-LTE、FDD-LTE；
China Telecom：CDMA、CDMA2000、TD-LTE、FDD-LTE.
It is above-mentioned not include the excessive standard that each generation communication technology generates in the process in speech also, thus it is not difficult to find out old China hand
The standard that letter industry is being on active service is many, and it is just more numerous that each operator is based on used frequency under various communication standards
Miscellaneous to differ, this communication present situation so that the arrangement and method for construction that signal covers is complicated, and difficulty of construction is big, easily formed coverage hole with
Ping-pong covers the difficulty and cost of signal optimization, public resource is caused to waste after also increasing.
In this case, multi-service compartment system (Multiservice Distributed Access System
Solution, MDAS) it comes into being, MDAS, as transmission medium, is supported Duo Jia operators, supports more systems using cable/optical fiber
Formula, multicarrier, and integrated WLAN (Wireless LAN, WLAN) system, a step solve voice and data service and need
It asks, improves the accuracy of signal covering, be greatly reduced the complexity of signal covering engineering and the difficulty of construction maintenance, with
Traditional analog compartment system is compared, and is provided simultaneously with mixed networking, delay compensation, automatic carrier track, uplink bottom are made an uproar the features such as low.
MDAS is mainly made of access unit (MAU/MU), expanding element (MEU/EU) and far-end unit (MRU/RU).
MDAS basic functional principles are as follows：
Downlink (base station --->User)：The signal of base station/RRU is linked into after system and carries out number to signal by MU
Processing is packed into digital signal, then converts digital signals into optical signals optical fiber by opto-electronic conversion and be transmitted to EU；EU will
The signal that MU is transmitted by optical fiber is handled, then is transferred to RU by optical fiber；The signal processing that RU transmits EU amplifies
Afterwards, covered away by antenna, be transferred to user.
Uplink (user --->Base station):After the information that user sends out is received by RU, RU to signal at
Reason is transferred to EU by optical fiber again；All RU signals transmitted are digitized after processing is packaged and form light by opto-electronic conversion by EU
Signal, then MU is transmitted to by optical fiber；After the digital signal of EU is packaged reduction by MU, base station/RRU is transferred to.
Nowadays in the market the most basic structure composition of multi-service optical fiber distribution system currently in use as shown in Figure 1, but
This basic structure can not meet actual application demand, and waste of resource, thus be by multi-service optical fiber distribution system
System basic structure has derived following several concentration networking modes used in practical application scene：
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 for 3 kinds of networking modes being made of basic structure is the extended capability using EU, EU support the extension of RU from
And realize star-like networking mode；EU supports are to the expansion cascading of EU so as to fulfill chrysanthemum type networking mode；Two kinds of extended capability collection
Use is closed so as to fulfill mixed networking mode.
The standard that the multi-service optical fiber distribution system of above-mentioned three kinds of networking modes is supported is with frequency range by a main access
Unit (MU) determine, when MU only supports the standard and frequency range of China Mobile 2G/3G/4G, no matter more industry of which kind of networking mode
Business optical fiber distribution system can only also cover and handle the communication service of China Mobile.It is needed if desired for the business of other operators is supported
Asking just needs to replace entire multi-service optical fiber distribution system, including MU, EU and RU or installs the whole series additional again and supports other operators
Standard and frequency range multi-service optical fiber distribution system.Such as：Unicom is extended on the basis of original has covered China Mobile's signal
It covers, is accomplished by the following way with telecommunication signal：
It adds respectively again and supports unicom and the standard of telecommunications and the optical fiber distribution system of frequency range to cover respective signal,
So realize that full signal covering need to just amount to 3 unjacketed optical fiber compartment systems, system rectification schematic diagram is as shown in Figure 5.
Above-mentioned realization method needs to set two sets or more of compartment system, realizes that the whole network covers and is required to again or repeatedly
Wholly-owned input, covering quantities will also be multiplied, and cause the wasting of resources.
As it can be seen that standard extension is carried out to the region covered using existing multi-service optical fiber distribution system to realize different location
The multiple access of information source, quantities can be multiplied with cost, original serious waste of resources.
