Description
Technical field
The present invention relates to communication technical field, particularly a kind of allocated bandwidth control technology.
Background technology
3GPP 25.435 (3GPP:3rd Generation Partnership Project, third generation communication partner tissue) agreement regulation, at HSDPA (High Speed Downlink Packet Access, the high speed downlink packet access) in the system, RNC (Radio Network Controller, radio network controller) uses HS-DSCH (High Speed Downlink Shared Channels, high speed descending sharing channel) transmitting high speed down data to the base station.
MAC-d (MAC-dedicated, special-purpose MAC) is a kind of of MAC (Medium Access Control, medium access control) entity, is positioned at the RNC side, is used to handle dedicated channel.And MAC-hs (MAC-high speed, high speed MAC) also is a kind of MAC entity, is positioned at base station side, is used to handle HS-DSCH.HS-DSCH uses following processes to carry out transfer of data.
RNC is by the data buffer zone size (each CAPACITYREQUEST control frame can only carry the information of a priority data among the MAC-d flow) of each priority among certain MAC-d flow of HS-DSCH requests for capacity (Capacity Request) control frame informing base station RNC side, and application sends data to the base station; HS-DSCH capacity allocation (CAPACITY ALLOCATION) control frame is passed through to the RNC partition capacity in the base station; RNC sends high-speed down data according to the capacity of getting to the base station.
According to predetermined parameter in the agreement, the factor that influences Iub mouth flow mainly contains three: the data volume of each priority data buffering area of RNC MAC-dflow; The buffer size of each priority data formation of MAC-hs and the situation that takies of buffering area; Time delay between the transmission of base stations control frame and Frame receive.
Based on above-mentioned factor, it is that data queue distributes the Iub interface bandwidth that prior art has adopted the flow control algorithm based on priority query's state.This method is provided with several thresholdings for the data queue of each priority, the data volume BO (t) in the priority data formation is detected in the base station, when finding that BO (t) is in certain section when interval, just the Iub interface bandwidth that the data queue of this priority takies is adjusted by transmission CAPACITY ALLOCATION frame.And this method also is provided with a bandwidth occupancy time threshold Th1, at each TTI (Transmission Time Interval, Transmission Time Interval), all data queues are traveled through, check that whether data queue takies the time of Iub interface bandwidth above this thresholding Th1, if surpass, then abandon institute's dedicated bandwidth, carry out the bandwidth application again.When system is data queue's distribution bandwidth, according to the stand-by period ordering, preferentially to long data queue's distribution bandwidth of stand-by period.
Prior art is not considered the actual factors such as speed that send to subscriber equipment of data in buffer in QOS (Quality of Service, the quality of service) demand of data queue and the data queue.Because all data queues of prior art fair play, and do not consider the QOS demand of data queue, if have (Guaranteed Bit Rate in the system for GBR, the assurance bit rate) data queue that has relatively high expectations, then can be less because of Iub interface bandwidth deficiency, data in data queue, transfer empty phenomenon and scheduling occurs, can't ensure assurance bit rate into data queue's configuration.Because prior art is considered as the buffering area of data queue the buffering area of a static state, cut apart the input and output of this buffering area, when carrying out the Iub interface flow control, only consider a problem from input, so usually make the BO (t) of data queue shake between each thresholding of setting, cause CAPACITY ALLOCATION frame too frequently to waste the Iub interface bandwidth through being everlasting.
This shows that prior art can not cause the Iub interface bandwidth waste reasonably for data queue distributes the Iub interface bandwidth, perhaps the Iub interface bandwidth of Fen Peiing can not ensure the assurance bit rate into data queue's configuration.

1, Bw1 is modified to Bw1*F3.
Wherein, F3 is the Iub interface bandwidth lifting factor in the time of can not satisfying the GBR demand, and its value need make revises back (Bw1-GBR) * 0.01＞Ld, and wherein Ld represents to send the MAC-d PDU length that data are used.Maximum that F3 is desirable and minimum value need satisfy following condition: make the data transmission rate that can adaptively eat dishes without rice or wine for the Iub interface bandwidth of user data queue assignment, wherein, the maximum of F3 can be got to make finally and equal entire I ub interface total bandwidth for the Iub interface bandwidth of user data queue assignment.Such as, the minimum value that F3 can be set for greater than 1 and less than any one value of 2, maximum is 2; In the practical operation, the span of F3 can be set between this maximum and minimum value, be [1.1,1.9], [1.3,1.7] etc. such as the span that F3 can be set.
2, Bw1 (n) is modified to
Wherein Ld represents to send the MAC-d PDU length that data are used.This is a kind of amendment scheme of simplification, because when distributing the Iub interface bandwidth, need be unit with MAC-d PDU length L d, promptly bandwidth can not continuous dispensing, be when Bw1 can not satisfy the GBR demand so revise purpose, get a minimum bandwidth allocation scheme that satisfies the GBR demand.
As seen, when determining the Iub interface bandwidth B w1 of user data formation demand in current subframe, the embodiment of the invention considered the air interface Mean Speed of the current subframe of user data formation, and when satisfying GBR, Bw1 just carries out follow-up S102-S103, thereby utilize the Iub interface bandwidth of the method for the embodiment of the invention for the user data queue assignment, can ensure assurance bit rate into user data formation configuration.
Distinguishingly, in step S101, if subscriber equipment has just inserted success, then the air interface actual speed rate is 0, and need determine the air interface Mean Speed of the current subframe of user data formation this moment according to the maximum of UE capability;
