Embodiment 6

[0159] Since the data packets are sent in the network, there will be time delay jitters. In view of this problem, the present application also provides a voice data transmission method based on the third embodiment. The corresponding embodiment six of the method is as follows:

[0160] In order to avoid time stamp calculation errors caused by excessive RTP jitter delays that cannot be eliminated, the periodic mechanism of buffering and flow information / time information can be used to correct errors; since the air interface transmits voice frames, the basic delay is small and exceeds the voice TTI The time of the frame is basically processed by discarding the frame, so there is basically no large delay jitter from the terminal to the base station; the main jitter is the network transmission delay jitter of the RTP voice data packet sent to the terminal. This error correction mechanism It is mainly implemented on the base station side. The base station can set a buffer, and the f...

Embodiment 3

[0164] Combined with the technical solution of Embodiment 3, the complete technical solution of this embodiment is implemented as follows, wherein, the UE and the base station can both be used as the sending end device or the receiving end device according to the scene where they are located:

[0165] In the first step, the terminal UE prepares for the SDAP direct bearer mode.

[0166] This step is specifically implemented as: expanding and defining the SDAP direct bearer processing capability supporting voice in the capability of the UE,

[0167] MS network feature support: VoiceOverSDAPCapability{

[0168] Enable 1;

[0169] Disable 0;

[0171] And report to the network side in the UE CAPABILITY INFO INDICATION reported by the UE to the network side, and the network side obtains the direct bearing capacity of the voice data of the terminal in SDAP.

[0172] In the second step, the base station prepares for the SDAP direct bearer mode.

[0173] First, define the...

Abstract

The invention provides a voice data transmission method and device, equipment and a storage medium, and the method comprises the steps of extracting voice data in an RTP data packet containing the voice data, directly transmitting the extracted voice data in an SDAP protocol layer through an SDAP PDU, cancelling the repeated transmission of an RTP / UDP / IP header, reducing the redundant transmission of the data of a voice service data packet header, improving the transmission efficiency of voice data, reducing the size of a data packet of wireless air interface voice data, improving the utilization rate and coverage of wireless resources, improving the quality of service (QoS) of voice services, and reducing the power consumption of the terminal.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a voice data transmission method, device, equipment and storage medium. Background technique [0002] With the continuous development of the wireless communication technology, the wireless technology has developed from the second generation communication technology (2nd Generation, 2G) to the fifth generation communication technology (5th Generation) technology. The data transmission of the wireless mobile Internet in the 5G technology system is mainly based on the Internet Protocol (IP) method. The voice solution in the first version of the 5G technology standard (R15) is a voice (Voice on New Radio, VoNR) bearer solution based on the IP Multimedia Subsystem (IMS) based on the new air interface system. Weak coverage area, switch to the fourth generation communication network (4th Generation, 4G), adopt the Voice on Long Term Evolution (VoLTE) solution based on the lon...
