Technical Field
The embodiment of the invention relates to communication technology, in particular to a processing method and a base station for voice service data packet transmission based on an internet protocol.
Background
The Long Term Evolution (LTE) technology is a standardization work started by The3rd generation partnership project (3 GPP) in The end of 2004, and aims to meet The challenges of broadband access technology and The requirements of new services.
For voice over internet protocol (VoIP) service based on Internet Protocol (IP), the LTE system mainly uses Semi-persistent scheduling (SPS) or dynamic scheduling to control the transmission of VoIP service data packets. Specifically, when the SPS method is adopted, the base station allocates a time-frequency resource to the VoIP service packet at time i, and transmits the VoIP service packet according to the allocated time-frequency resource at the cycle arrival time (i.e., time i + N) according to the configured cycle N. When a dynamic scheduling mode is adopted, the base station can apply for time-frequency resources for the received VoIP service data packet at each scheduling time, and transmit the VoIP service data packet according to the applied time-frequency resources.
In the prior art, when an SPS method is adopted and a network side has strong delay jitter, because a base station has already pre-allocated time-frequency resources for a terminal according to the size of a VoIP service data packet, the base station can only transmit one VoIP service data packet and one VoIP service data packet according to the pre-allocated time-frequency resources, which causes aggravation of voice delay, further reduces quality of service (QoS), and affects perception of users. In addition, when a dynamic scheduling mode is adopted, when the overhead of Physical Downlink Control Channel (PDCCH) resources is increased and the time interval for allocating time-frequency resources is changed too much, the QoS is also reduced, and the perception of the user is affected.

the arrival time is the moment when the radio link control layer receives the voice service data based on the Internet protocol; i represents the time when the voice service data packet based on the internet protocol is allocated with time-frequency resources; n represents the period of the voice service data packet based on the Internet protocol, and m is a positive integer.
11. The base station of claim 10, wherein the semi-persistent scheduling transmission processing module is further configured to transmit the voice over internet protocol data packet of the earliest arriving base station in a semi-persistent scheduling manner when the voice over internet protocol data packet of the earliest arriving base station does not generate jitter;
the dynamic scheduling mode transmission processing module is further specifically configured to apply for the remaining voice over internet protocol data packets in the cache of the radio link control layer for idle time-frequency resources and physical downlink control channel resources through a dynamic scheduling mode when the remaining voice over internet protocol data packets jitter, and transmit the remaining voice over internet protocol data packets at the time of application if the idle time-frequency resources and the physical downlink control channel resources are applied.
12. The base station of claim 10, wherein the dynamic scheduling transmission processing module is further configured to apply for the two or more voice over internet protocol packets in the buffer of the radio link control layer for idle time-frequency resources and physical downlink control channel resources through a dynamic scheduling mode when the two or more voice over internet protocol packets jitter, and transmit the voice over internet protocol packets at the time of application if the idle time-frequency resources and physical downlink control channel resources are applied.
