  • the present invention relates to the field of communication technologies, and specifically relates to a QoS (Quality of Service) scheduling method and a server according to a PHR (Power Head Room). Background technique
  • QoS includes the bandwidth of transmission, the delay of transmission, and the packet loss rate of data.
  • the quality of service can be improved by ensuring the bandwidth of transmission, reducing the delay of transmission, reducing the packet loss rate of data, and delay jitter.
  • Network resources are always limited. In order to ensure the quality of services, there are situations in which network resources are seized. The quality of service is relative to the network service. While ensuring the service quality of a certain type of service, it may damage the service quality of other services. For example, if the bandwidth of a certain type of service is more than the bandwidth of a certain type of service, the less bandwidth used by other services may affect the use of other services.
  • a certain type of service is always scheduled, the scheduling of other services will be less, and the use of other services will be affected. At the same time, due to the lack of scheduling, it will affect the delay and packet loss of other services. If the service with poor channel quality occupies a large bandwidth or is always scheduled, it will affect other services with good channel quality and affect the throughput of the entire system. This is because the service with poor channel quality is preferentially scheduled. This type of service occupies a large amount of system bandwidth, and due to poor channel quality, although a large amount of system bandwidth is occupied, the number of effective bits that can be transmitted does not increase significantly; if these bandwidth transmission channels have good quality, the transmission can be made effective. The number of bits is greatly increased, so that the throughput of the entire cell can be improved.
