Claim of US Patent No. 10,342,025

1. A scheduling method for voice data, comprising:determining whether semi-persistent scheduling is enabled, and whether a User Equipment, UE, supports the semi-persistent scheduling;
in response to that the semi-persistent scheduling is not enabled or the UE does not support the semi-persistent scheduling, determining whether dynamic delay scheduling is enabled, wherein the dynamic delay scheduling comprises scheduling by binding two consecutive voice data packets; and in response to that the dynamic delay scheduling is enabled, implementing the dynamic delay scheduling;
wherein the scheduling by binding two consecutive voice data packets comprises:
acquiring two voice data packets arriving consecutively in a preset time interval;
acquiring attribute information of the two voice data packets and transmitting the attribute information to a Media Access Control, MAC, layer;
reserving a buffer space with a certain size in a buffer according to the attribute information of the two voice data packets; and
scheduling the two voice data packets in the reserved buffer space;
wherein the scheduling of the two voice data packets in the reserved buffer space comprises:
during an uplink dynamic delay scheduling, judging whether uplink data with a Logical Channel Group, LCG, equal to 1 exists; if any, inserting the uplink data to an uplink scheduling queue, and registering an uplink reserved buffer space; and
during a downlink dynamic delay scheduling, judging whether downlink data with a QoS Class Identifier, QCI, equal to 1 exists; if any, inserting the downlink data to a downlink scheduling queue, and registering a downlink reserved buffer space.
