Problems solved by technology

[0009] It can be seen from the above that the voice service dynamic scheduling resource allocation scheme in the prior art has the following defects: the existing method is implemented according to the protocol, and does not consider the relatively small characteristics of the voice packet, and it is easy to use the TYPE0 resource allocation method in the TM3 mode. This causes a waste of PRB resources, especially when the voice users in the base station reach a certain load, and the users at the good or midpoint of the base station adopt DCI 2A scheduling in TM3 mode, which causes a waste of resources, and TYPE0 / TYPE2 resources are allocated in the same sub When the frame is in progress, resource fragments are easily generated, and channel resources are not allocated reasonably, which reduces the overall capacity of the base station

Abstract

The present invention provides a downlink dynamic scheduling resource allocation method, device and base station for VOLTE services. The method includes: acquiring a first count value of a user equipment UE whose number of consecutive downlink subframes is equal to or greater than a first preset value, The UE is a UE whose service type is a voice service, and whose downlink transmission mode is TM3 mode; judge whether the first count value is greater than a second preset value, and if so, use the downlink control information format DCI 1A to perform an operation on the UE Resource scheduling, otherwise, determine the DCI format used for downlink scheduling according to the adaptive algorithm of the TM3 mode, and perform resource scheduling on the UE according to the determined DCI format. The present invention can reduce the use of PRB resources of good-point and mid-point voice users, reduce the waste of channel resources, and improve the user capacity of the base station and the utilization rate of air interface resources.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a downlink dynamic scheduling resource allocation method, device and base station for VOLTE services. Background technique [0002] At present, in the mobile communication network system, VOLTE is an end-to-end voice solution based on the all-IP condition of the LTE network. VOLTE (Voice Over LTE, voice service based on LTE) is a packet switching service based on the PS (Package Switch) data domain. VoIP (voice over internet protocol, voice service based on IP protocol) voice data packets arrive periodically, and the packet size Relatively fixed features. Currently the most commonly used voice packet formats are standard definition voice with a voice coding rate of 12.2K, that is, narrowband (NB_AMR) voice data packets, and high-definition voice with a voice coding rate of 23.85K, that is, wideband (WB_AMR) voice data packets. The number of bytes of the two...
