Down dynamic scheduling resource distribution method, device and base station for VOLTE service

Abstract

The invention provides a down dynamic scheduling resource distribution method, device and base station for a VOLTE service. The method comprises the steps of obtaining a first count value of user equipment (UE) which is equal to or larger than a first preset value in number of continuous down subframes, wherein the service type of the UE is voice service, and the down transmission mode of the UE is the TM3 mode; judging whether the first count value is larger than a second preset value, if yes, adopting the down control information format DCI 1A for conducting resource scheduling on the UE, otherwise, determining the DCI format adopted for conducting the down scheduling according to the adaptive algorithms of the TM3 mode, and conducting resource scheduling on the UE according to the determined DCI format. By means of the down dynamic scheduling resource distribution method, device and base station for the VOLTE service, use of PRB resources by voice users at good points and medium points is reduced, waste of channel resources is lowered, and the user capacity of the base station and the using efficiency of unoccupied resources are raised.

Description

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

AI Technical Summary

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
