A method and device for determining terminal scheduling priority

Abstract

The invention provides a method and a device for determining a scheduling priority of a terminal. In the service scheduling process, the residual activation time of the terminal is taken into consideration, the probability of scheduling the terminal with shorter residual activation time is increased, and the probability of entering a sleep state when the terminal is not scheduled is reduced. By the invention, the terminal with shorter residual activation time is preferentially scheduled to a certain extent, and the probability of entering the sleep state of the terminal is reduced, so that a packet loss rate of time-delay sensitive service caused by exceeding the maximum time-delay constraint is reduced, and the power consumption efficiency of a system is improved.

Description

technical field [0001] The invention relates to a service scheduling technology in the communication field, in particular to a method and device for determining terminal scheduling priority under a discontinuous reception mechanism. Background technique [0002] With the concept of green environmental protection, energy saving and emission reduction gradually gaining popularity, people have higher speed and more colorful services, and at the same time, they put forward further requirements for the battery life of the terminal. Moreover, the continuous development of wireless communication technology, the introduction of various new technologies and the increase of system complexity have also brought severe challenges to the power consumption of terminals. Therefore, an effective method must be found to optimize the energy efficiency of the terminal, and the discontinuous reception (DRX, Discontinuous Reception) mechanism is just one of the important ways to optimize the ener...

Problems solved by technology

However, since delay-sensitive services have maximum delay constraints (such as figure 2 T6 in ), when the packet waiting time exceeds the maximum delay limit condition T6, the packet will be discarded by the network side, which will lead to an increase in the packet loss rate of the service, and make terminal 2 lose Possibility of re-competing for scheduling opportunities

[0016] From the above analysis, it can be seen that the service scheduling method under DRX in the prior art does not take into account the impact brought by DRX application, so the scheduling result is unreasonable, which may easily lead to the deterioration of user QoS
