Description

Carry out QoS dispatching method and server according to PHR

Technical field

The present invention relates to communication technical field, specifically is that ((Power Head Room, transmission power) carried out QoS (Quality of Service, service quality) dispatching method and server according to PHR.

Background technology

In Network, QoS comprises the time delay of transfer bandwidth, transmission, the packet loss of data etc.In network, can improve service quality through guaranteeing the measures such as time delay, the packet loss that reduces data and delay variation that transfer bandwidth, reduction transmit.Internet resources are always limited, in order to guarantee service quality, just exist the situation of seizing Internet resources.Service quality is relative Network, in the service quality that guarantees certain type of business, possibly be exactly in other professional service quality of infringement.For example, under the fixing situation of the network bandwidth, if the bandwidth that certain type of business takies is many more, other professional bandwidth of using is few more so, may influence other professional use.If certain type of business always obtains scheduling, other professional dispatcher can be just few so, also can influence other professional use; Owing to can not get scheduling, also can influence other professional time delay, packet loss etc. simultaneously.If bad big perhaps always the obtaining of bandwidth occupied by service of channel quality dispatched; Will influence the good business of other channel quality so, also can influence the throughput of whole system simultaneously, this is because the professional priority scheduling of bad channel quality; Will make this type of business occupy a large amount of system bandwidths; And because bad channel quality, though take a large amount of system bandwidths, the significant bit number that can transmit can't roll up; If the business that these bandwidth for transmission channel qualities are good can make the significant bit number of transmission roll up, thereby can improve the throughput of whole sub-district.

Can find out that through above-mentioned example how dissimilar business seizes system bandwidth becomes the key factor that satisfies QoS, also be the key factor that improves cell throughout.And in wireless system, uplink communication is that the emission of UE (subscriber equipment) is a power limited, means up available system bandwidth, and the significant bit number of transmission is limited.In the prior art, the priority of the UE preempting resources of QoS adopts PF (Proportional Fair, the equitable proportion) factor and the factor whether other business satisfies to combine, and does not consider the transmission power situation of this UE.
