Description
Technical field
The present invention relates to moving communicating field, particularly mobile communication system and relevant communication means.
Background technology
Along with development of human society, the requirement of mobile communication technology is improved constantly and variation, therefore occurred first in succession to 3G (Third Generation) Moblie.
This causes existing different wireless access technologys at present moving communicating field, also has the wireless network based on different technologies thus.Based on the wireless network of different technologies global system for mobile communications (Global System for Mobile Communication in the second generation mobile communication is arranged, be called for short " GSM "), code division multiple access (Code Division Multiple Access, be called for short " CDMA "), Wideband Code Division Multiple Access (WCDMA) in the 3G (Third Generation) Moblie (Wideband Code Division Multiple Access, be called for short " WCDMA "), TD SDMA (Time Division Synchronous CodeDivision Multiple Access, be called for short " TD-SCDMA ") and CDMA 2000 (Code DivisionMultiple Access 2000 is called for short " CDMA2000 ") or the like.
Based on different technology, wireless network provides the ability of wireless traffic uneven.3-G (Generation Three mobile communication system) such as WCDMA provides the ability of wireless traffic just to be better than the second generation mobile communication system such as GSM greatly.For example WCDMA can provide high-speed data service, but GSM does not just accomplish.
On the other hand, in order to satisfy the requirement of the wireless traffic that different networks provides, the ability of user terminal also becomes more and more stronger along with the continuous new business of releasing of wireless network in recent years, many terminals can be supported two or more wireless traffics simultaneously, for example carry out data service communication etc. simultaneously in conversation.

The transmission medium of realizing terminal room communication mainly contains radio wave, infrared ray etc., because that radio wave exists is weak, and frequency is high more, and radio wave is got over piece with range attenuation.Therefore the high workload frequency will cause the coverage of base station in the network very limited, and at this point, prior art adds radio repeater station in network, with the scope of increase system covering.
Radio repeater station communicates by air interface and base station, and transmits the data of terminal.Because the complexity of relay station is more much smaller than traditional base station, and the characteristics of radio repeater station maximum are that it does not need cable to be connected with network, the flexibility of its laying is bigger than the traditional base station, therefore under identical systematic function requires, comprise the coverage of system and throughput etc., the cost of building relay station is littler than building the base station.The characteristic of relay station also makes it to be laid fast, and operational expense is also smaller.Therefore, use relay station, can obtain bigger covering with lower cost, these advantages also will enlarge the market demand of radio bandwidth access network.
Yet, along with the introducing of relay station, and people's raising that existing network is required, the protocol infrastructure of existing air interface can't be supported developing mobile communications network well, the many technical functionalitys that can't support occurred, for example:
1. can't support the function of relay station;
2. can't support the data between the user not pass through the function of base station direct communication;
3. can't support the seamless switching between the different system, the function of load balancing and frequency spectrum share;
4. in the same system, the physical layer of different mode, as for (the Frequency Division Duplex of Frequency Division Duplexing (FDD) in the same system, be called for short " FDD ") pattern and time division duplex (Time DivisionDuplex, be called for short " TDD ") physical layer of pattern, do not support the coordination function of two kinds of patterns;
5. can't separately encrypt user face data and chain of command data.
