Abstract

The invention relates to a method for carrying out QoS scheduling according to PHR and a server. The method comprises the following steps: carrying out updating processing of the PHR on user equipment (UE) which reports the power head room (PHR); counting all UE to be scheduled in a cell, and according to updated PHR, calculating an equivalent signal to noise ratio (SINR) when converting the UE to be scheduled into a single resource block (RB); according to the equivalent SINR, obtaining a data packet size TBSize of the UE to be scheduled; according to the TBSize, calculating a priority factor of the UE to be scheduled; scheduling the UE to be scheduled according to the priority factor of the UE to be scheduled. According to the method for carrying out the QoS scheduling according to the PHR and the server, priority ordering is carried out through the power head room of the UE, thus uplink QoS priority calculation is more reasonable, throughput of a system cell is raised, and the stability of a system is raised.

Description

QoS dispatching method and server is carried out according to PHR

Technical field

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

Background technology

In Network, QoS comprises bandwidth, the time delay of transmission, the packet loss etc. of data of transmission.In a network can by ensureing that the measures such as the bandwidth of transmission, the time delay reducing transmission, the packet loss reducing data and delay variation are improved service quality.Internet resources are always limited, in order to guarantee service quality, just there is the situation seizing Internet resources.Service quality is Relative Network business, while the service quality ensureing certain class business, may be exactly the service quality in other business of infringement.Such as, when the network bandwidth is fixing, if the bandwidth that certain class business takies is more, so the bandwidth of other business use is fewer, may affect the use of other business.If certain class business is always dispatched, so the dispatcher of other business can be just few, also can affect the use of other business; Simultaneously owing to can not get scheduling, the time delay of other business also can be affected, packet loss etc.If the bad bandwidth occupied by service of channel quality is dispatched greatly or always, so will affect the good business of other channel quality, also can affect the throughput of whole system simultaneously, this is because the business priority scheduling of bad channel quality, this type of business will be made to occupy a large amount of system bandwidths, and due to bad channel quality, although take a large amount of system bandwidths, the significant bit number that can transmit can't roll up; If the measured business of these bandwidth transmission channels matter, the significant bit number transmitted can be made to roll up, thus the throughput of whole community can be improved.

Can be found out by above-mentioned example, how dissimilar business seizes system bandwidth becomes the key factor meeting QoS, is also the key factor improving cell throughout.And in radio systems, uplink communication is the transmitting of UE (subscriber equipment) is power limited, mean up available bandwidth, the effective number of bits of transmission is limited.In prior art, the factor whether priority of the UE preempting resources of QoS adopts other business of PF (Proportional Fair, equitable proportion) Summing Factor to meet combines, and does not consider the transmission power situation of this UE.
