Problems solved by technology

[0005] In the process of uploading the existing voice data, because DCI0 needs to be called first, the 4 PRBs corresponding to the fixed MCS level are uploaded to the BSR. All voice data is uploaded, resulting in an increase in the delay for voice data from one terminal to another

Embodiment Construction

[0052] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0053] One of the core ideas of the embodiment of the present invention is that the embodiment of the present invention can determine the status information of the voice service, and when the uplink scheduling request SR is detected, the encoding format and IP header feature information of the previously uploaded voice data packet can be respectively extracted and IP protocol version information, using the encoding format, the IP header feature information and the IP protocol version information to calculate the packet size information of the voice data packet that needs to be uploaded this time, according to the IP header feature information, packet size information and status Information, determine the size of the BO that needs t...

Abstract

The embodiment of the invention provides an uplink resource allocation method and device based on an uplink scheduling request (SR) in a VoLTE (Voice over LTE) voice service. The method comprises the following steps: determining status information of the voice service; when an uplink SR is detected, extracting a coding format, IP (Internet Protocol) header feature information and IP protocol version information of an uploaded voice data packet respectively; determining packet size information of a voice data packet needing to be uploaded at that time by the coding format, the IP header feature information and the IP protocol version information; determining the size of buffer occupancy (BO) needing to be allocated according to the IP header feature information, the packet size information and the status information; determining a modulation and coding scheme (MCS) level; and determining the number of physical resource blocks (PRBs) needing to be allocated according to the size of the BO needing to be allocated and the MCS level. Through adoption of the uplink resource allocation method and device in the embodiment of the invention, the time delay of voice data from one terminal to another terminal can be shortened.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for allocating uplink resources based on an SR in VoLTE voice services and an uplink resource allocation device based on an SR in VoLTE voice services. Background technique [0002] In the TD-LTE system, VoLTE (Voice over LTE) is an IMS-based voice service, and all its services are carried on the 4G network, which can realize the unification of data and voice services under the same network. Compared with 2G and 3G voice services, VoLTE voice services It has the advantages of shorter waiting time for connection and higher quality and more natural audio and video calls. [0003] In the existing practice, VoLTE voice services usually upload voice data in the following ways: [0004] When the terminal needs to upload voice data to the base station, the terminal sends an uplink scheduling request (Scheduling Request, SR) to the base station, and the base st...
