Problems solved by technology

[0004] However, high-speed and high-quality VoLTE services need to occupy certain network resources, and the resources that base stations in LTE systems can provide are limited. When resources are limited, it will seriously affect the service experience of VoLTE users

Embodiment Construction

[0029] The invention discloses a congestion control method for VoLTE users in an LTE system. When resources are congested, VoLTE users with high loads are dropped back to the CS domain to perform services such as voice by triggering CSFB of newly accessed VoLTE users. Among them, "triggering CS domain fallback for newly accessed VoLTE users" refers to: when a newly accessed VoLTE user needs to establish a session, fall back the UE to the 2G / 3G CS network, and complete the entire call process in the CS domain. Newly accessed VoLTE users include: VoLTE users who have accessed the LTE network but have not yet established a session and VoLTE users who are requesting access.

[0030] The actual congestion control is performed after the user accesses, but when the UE turns on the VoLTE function during the test, if the bearer with QCI=5 is released, it will keep requesting to establish the bearer with QCI=5 until the establishment is successful. In order to prevent the UE from contin...

Abstract

The invention discloses a congestion control method for VoLTE users in an LTE system. The set congestion threshold value is compared and judged whether the triggering congestion control condition is met; when the triggering congestion control condition is met, it is judged whether it is a newly accessed VoLTE user; for the newly accessed VoLTE user, the method of triggering CSFB is used. congestion control. The present invention innovatively applies CSFB technology to the wireless reception technology field of the LTE system. When resources are congested, VoLTE users with high loads fall back to the CS domain to perform services such as voice, so that VoLTE users' call services will not be unable to complete due to resource congestion. , reduce the impact of limited base station resources on VoLTE user service experience, and ensure the QoS performance of remaining users and bearers within the congestion threshold.

Description

technical field [0001] The present invention relates to the technical field of LTE system wireless reception, in particular to a congestion control method for VoLTE users. Background technique [0002] Long Term Evolution (LTE) is a resource sharing system, and all users share resources through scheduling. Due to the limitation of air interface wireless resources and equipment hardware resources, to ensure the quality of service (Quality of Service, QoS) of the bearer, the base station can only support a certain number of users and bearers. The base station needs to control the admission of users requesting access and established bearers, so that as many users and bearers as possible can be accessed while ensuring the QoS of the accessed bearers, and the system capacity and resource utilization can be improved. [0003] The full name of VoLTE is "Voice over LTE", which is an LTE voice solution based on IP Multimedia Subsystem (IMS). VoLTE technology accesses the IMS core n...
