Problems solved by technology

[0009] It can be seen from the above prior art that when the base station performs resource scheduling, it only considers the channel conditions at that time, but does not consider the traffic quality requirements of VOLTE services in different coding formats, so that it cannot meet the quality requirements of different services, which leads to The allocation of PRB resources is not optimized enough

Embodiment 1

[0044] Such as figure 1 As shown, the resource scheduling method of VOLTE in this embodiment includes:

[0045] Step S1: determine the encoding format of the voice packet according to the corresponding RTP packet of the voice packet;

[0046] Step S2: Predict the data volume and sending interval of the voice packet to be sent according to the encoding format;

[0047] Step S3: Scheduling PRB resources to transmit the to-be-sent voice packet according to the amount of data and the transmission interval.

[0048] The RTP (Real-time Transport Protocol) is an Internet protocol standard that describes the way a program manages the real-time transmission of multimedia data.

[0049] The composition of RTP includes sequence number, payload identification, PT field and time stamp, etc. Wherein the sequence number is used to detect lost packets. The payload identifier is used to describe the encoding of the media. The PT field is the type of payload, usually occupying 7 bits, and ...

Embodiment 2

[0060] Such as figure 2 As shown, the resource scheduling method of VOLTE in this embodiment includes:

[0061] Step S1: determine the encoding format of the voice packet according to the corresponding RTP packet of the voice packet;

[0062] Step S2: Predict the data volume and sending interval of the voice packet to be sent according to the encoding format;

[0063] Step S3: Scheduling PRB resources to transmit the to-be-sent voice packet according to the amount of data and the transmission interval.

[0064] Step S4: Obtain the code stream speed of the RTP packet, and determine whether the code stream speed of the RTP packet has changed, and return to step S1 if there is a change, and return to step S3 if there is no change.

[0065] The code stream speed of the RTP packet has changed, usually indicating that the parameters of the voice packet have changed, so that the code stream speed of the RTP packet is obtained by step S4 in this implementation, thereby obtaining th...

Embodiment 3

[0071] On the basis of the technical solution described in Embodiment 1 or 2, this embodiment may further include step S3' adjusting the size of the scheduled PRB resource according to the time delay and / or retransmission times of the voice packet.

[0072] Specifically, for example, the compression rate of the encoding format G.711a / u is relatively high, so that there is a lot of redundant information in the corresponding voice packets, so that the number of retransmissions can be appropriately reduced. Specifically, the number of retransmissions can be set to 0 or 1, so that the corresponding PRB resource occupation and retransmission times can be reduced.

[0073] For example, the encoding format G729 has a relatively high compression rate and a large transmission delay. It is sensitive to the loss rate, so it can increase the number of retransmissions and reduce the delay, so that when scheduling PRB resources, the PRB resources used for retransmission As the resource allo...

Abstract

The invention discloses a VOLTE resource scheduling method and device, which relate to the communication field and are mainly used to solve the waste of PRB resources caused by PRB resource scheduling only based on the current channel state in the prior art and the quality of some voice communication not meeting the requirements designed for such issues. The resource scheduling method of VOLTE of the present invention comprises: step S1: determine the coding format of voice packet according to the RTP packet corresponding to the voice packet; step S2: predict the data volume and transmission interval of the voice packet to be sent according to the coding format; step S3 : Scheduling PRB resources to transmit the to-be-sent voice packet according to the data amount and the sending interval. The invention has the advantages of reasonable allocation of PRB resources, VOTLE communication quality conforming to various communication requirements, easy realization and the like.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a VOLTE resource scheduling method and device. Background technique [0002] VOLTE (Voice Over LTE, voice service based on LTE) is a packet switching service based on the PS (Package Switch) data domain. Compared with the traditional voice service based on the CS (Circuit Switch) circuit bearer domain, it improves user experience, such as The communication quality is high, the call connection time is short, and the seamless integration with RCS can bring rich services. [0003] In the existing VOLTE resource scheduling process, when a user UE (User Equipment) initiates a VOLTE service, the base station mostly uses semi-persistent scheduling to transmit voice packets based on VOLTE. [0004] In semi-persistent scheduling, the base station continues resource scheduling according to the following steps; [0005] Step 1: Configure PRB resources (Physical Resource Block...
