Description
Technical field
The present invention relates to communication technical field, relate in particular to base station services method for ensuring quality and device in a kind of wireless communication system.
Background technology
In the wireless communication system, the base station is to show the equipment that the terminal provides service, carries out radio communication through electromagnetic wave between base station and the terminal.Wireless communication system can provide wireless coverage for the terminal of managing scope definitely through the base station, and this geographic range is called the sub-district.
Usually, wireless communication system is in order to need to dispose the big base station of coverage on a large scale for the user provides radio communication.This base station is commonly referred to macro base station (Macro BS), and its cell covered is commonly referred to Hong Qu (Macro Cell).Simultaneously, wireless communication system is considered user's different demands and different environments for use, need be for the user provide higher-quality radio communication service under some environment or scene, and the base station that some coverages are little, transmitting power is lower thereby be used.These small base stations comprise little base station (Micro BS), little base station (Pico BS) and sub-base stations (Femto BS) (also can be called Home eNodeB, personal base station).A macro base station maximum can cover the zone of circumference 2-3 kilometer, and the coverage of sub-base stations is no more than 30 meters.Because the huge difference of their coverages, the sub-base stations that in the coverage of macro base station, possibly be deployed with a large amount of (hundreds of even thousands of) is to improve indoor telecommunication service quality, and is as shown in Figure 1.
Along with the development of radio open technology, wireless base station of future generation has the high speed data transfer ability to satisfy people's demand growing to speed, can reach tens bandwidth of air-interface to hundreds of million like present LTE and WiMAX standard.The two-forty of eating dishes without rice or wine has been brought the requirement to the transmission rate between base station and the gateway/base station controller, and is as shown in Figure 2, and base station (eNodeB) is connected the forwarding that must support the up and downlink data in base station with transmission between the gateway (Serving GW).The mode that being connected between base station and the gateway/base station controller adopts the E1/STM-1/ Ethernet interface to use optical transmission to insert usually, like SDH, GPON etc.When system deployment, according to the traffic demand of base station and gateway/base station controller, this dedicated transmissions connects and is configured to satisfy the transfer of data between base station and the gateway/base station controller.
And in the environment of Home eNodeB, for example: sub-base stations, as shown in Figure 3, sub-base stations inserts through public telephone network, like the DSL netting twine of dwelling house inside.Transmission between sub-base stations and the sub-base stations gateway will be passed through the transmission of DSL.The DSL of family netting twine only can provide several million bandwidth usually, and this bandwidth of several million also will provide Connection Service for notebook or the other-end equipment that inserts through wired mode in the family simultaneously.The true bandwidth of DSL receives the influence of the congested and cell flow of backbone network toward the contact meeting in addition, downloads most of bandwidth that will account for the sub-district outlet like neighbours' P2P.The bandwidth that therefore, can be used between sub-base stations and the sub-base stations gateway the up and downlink data of transmission is usually much smaller than bandwidth of air-interface and fluctuation often.This shows that have bigger difference between the bandwidth of air-interface of sub-base stations and the transmission bandwidth, packet is very likely lost at sub-base stations when transmission bandwidth is congested.Certainly, also may there be the problems referred to above in macro base station when carrying out the lot of data business.
