Background technology
In the wireless communication system based on code division multiple access HRPD (high rate packet data) Evolution-Data Optimized version B (CDMA HRPD EVDORevB), when terminal to apply forward direction QoS business, the data of forward direction QoS business are assigned on each bearing carrier wave by base station controller and send.QoS flow, namely carries the data word throttling of QoS business, according to maximum traffic delay, maximum delay shake, minimum throughout, these four indexs of maximum packet loss, is mainly divided into time delay sensitive type, throughput sensitive type and delivery type three major types business of doing the best.Wherein, time delay sensitive type business refers to has strict demand (general allow maximum traffic delay between 200 to 600 milliseconds) to maximum traffic delay and the data service of not being strict with other three indexs; Throughput sensitive type business refers to the data service that there are certain requirements maximum delay shake and minimum throughout and be not strict with other two indices; As possible delivery type business refers to has strict demand to maximum packet loss and the data service of not being strict with other three indexs.
At present, in multi-carrier systems, when supporting the terminal of multicarrier function to start to communicate with base station, base station controller is that terminal sets up multiple bearing carrier wave, and according to the forward direction QoS business of terminal to base station controller application, the data allocations of forward direction QoS business is sent to terminal by base station controller to each bearing carrier wave; After terminal receives the data that each carrier wave sends, at bottom these data assemblies become complete forward direction QoS business data packet and submitted to upper strata.Wherein, base station controller distributes for each bearing carrier wave the mode that data to be sent adopt, and from current realization, mainly contains two kinds: a kind of is be evenly distributed on each bearing carrier wave by the data of forward direction QoS business; Another kind is Flow Control Window size (i.e. the ability of each bearing carrier wave transmission) pro-rata according to each bearing carrier wave application.These two kinds of methods of salary distribution are browsed for such as file transfer protocol (FTP) (FTP), webpage (Web), video playback etc. is as possible for delivery type or throughput sensitive type business, terminal can be made on the one hand to obtain higher throughput, the level that base station throughput also can be made to reach higher on the other hand.But, for time delay sensitive type business, the particularly little and business that requirement of real-time is very high of speed, because the data of forward direction QoS business are through different bearing carrier waves, so the time of data incoming terminal is impossible definitely according to the alignment of initial data byte stream order, therefore general needs opens up certain buffering area in terminal, for the data that these bearing carrier waves of buffer memory are sent, after all arriving Deng all data of a complete forward direction QoS business data packet, the data of these buffer memorys are become complete forward direction QoS business data packet according to initial data byte stream sequential combination by terminal again, then upper strata is submitted to.As seen from the above description, in order to wait for reaching of all data, certain time delay will be produced.If some time delay sensitive type business is very high to requirement of real-time, when sometimes also not waiting until in buffering area that all data of a complete forward direction QoS business data packet arrive, bottom just must submit to upper strata according to the time requirement of harshness, cause forward direction QoS business data packet group can not be bundled into merit, thus affect the integrality of data service, and then impact uses the experience of the user of time delay sensitive type business.
