Description

Service flow modification method and apparatus
The application is application number is 201280012561.2, the applying date be March 6 in 2012 day, be called the divisional application of the Chinese invention patent application of " business flow establishing method and device and service flow modification method and apparatus ".
Technical field
The invention belongs to wireless communication field, particularly relate to service flow modification method and apparatus.
Background technology
In recent years, wireless communication system develops rapidly, such as based on the wireless local area network technology WiFi of 802.11 standards, bluetooth (Bluetooth) system based on 802.15 and Femto technology towards indoor application of being derived by mobile communication system etc., it is obtained for and is widely applied.
WiFi technology based on 802.11 is a kind of wireless network transmission technology that current use is the widest. Owing to WiFi system have employed carrier sense/conflict avoidance (CSMA/CA, CarrierSenseMultipleAccesswithCollisionAvoidance) mechanism, system effectiveness is relatively low, and waste of radio resources is bigger. To cause the basic reason of this problem be CSMA/CA mechanism is a kind of random multi-access channel mechanism based on competition, central access point (CAP, and website (STA AccessPoint), Station), or between different STA, the right to use of CSMA/CA mechanism competition Radio Resource can be passed through, compete wireless channel simultaneously, now just collide, cause the waste of Radio Resource. In order to avoid collision, CSMA/CA mechanism require CAP or STA compete wireless channel time need random back, when all CAP and STA keep out of the way, though wireless channel is available free, but and be not used by, this is also the significant wastage to wireless channel. For above-mentioned reasons, 802.11 system effectivenesies are relatively low. Such as: 802.11g system physical layer peak rate up to 54Mbps, but TCP layer under big packet downloading service achievable rate not higher than 30Mbps. Although there is disadvantages mentioned above, but 802.11 systems are flexible, are independent of centralized Control mechanism, also therefore are able to realize relatively low equipment cost.
Femto technology based on 3GPP standard is a kind of new technique towards in-door covering come from mobile communication system evolution. Based on the data statistics to 3G system, the data service of about 70% all occurs in indoor, and therefore indoor high-speed rate data access scheme is just particularly important. Femto base station, is called femto base station, and compact (is similar to Wi-Fi), disposes flexibly. Owing to from mobile communication system evolution, Femto base station almost inherits all features of mobile communication system. Equipment disposal ability, simply in conjunction with application scenarios features such as its limited coverage, less access users, is reduced by Femto equipment, and then reduces equipment cost. Considering from duplex mode, identical with mobile communication system, Femto base station can be divided into FDD and TDD two class duplex mechanism. FDD up-downgoing carrier resource is symmetrical, and the asymmetrical service feature of data service up-downgoing data traffic makes FDD system there is certain wasting of resources when data service. TDD system uplink downlink is operated on same carrier wave, is that uplink downlink distributes different Radio Resources by time division resource, therefore can the better adaptive asymmetrical data service of up-downgoing business demand compared with FDD. But, the TDD duplex mode that mobile communication system (includes Femto system), up-downgoing resource static allocation, in the face of the Various types of data business that demand is different, for instance: browse webpage, mobile video, moving game etc., it is difficult to realize the dynamic adaptation that business demand divides with resource. Compared with Wi-Fi, owing to Femto have employed the centralized Control mechanism based on scheduling, base station or be absent between CAP and terminal or terminal due to competition conflict and the waste of radio resources that causes of random back, therefore link efficiency is higher.
Data transmission in wireless communication system, refers to Correspondent Node by completing data transmit-receive alternately, and this can be mutual between network side and terminal alternately, it is also possible to be mutual between terminal.
Finer in order to manage, it is desirable to different data can be transmitted respectively based on multiple links between Correspondent Node, namely transmit based on the data of Business Stream, thus there is the demand of service flow management.
