Method for controlling network transmission time delay, service quality control entity, and communication device

Abstract

The invention discloses a method for controlling network transmission time delay, a service quality control entity, and a communication device. The method includes the steps: sending a traffic flow delay threshold to a communication device according to a transmission delay requirement of a service flow, wherein the communication device includes a network device and/or user equipment; receiving a time-delay-exceeding-threshold indication send by the communication device, wherein the time-delay-exceeding-threshold indication is used to indicate that the transmission delay of the service flow exceeds the service flow delay threshold; and determining a delay control strategy according to the time-delay-exceeding-threshold indication, so that the communication device that sends the delay control strategy performs the delay control strategy. According to the invention, the method monitors the network transmission delay by setting a service flow delay threshold, and when determining that thetransmission delay of the service flow cannot be satisfied, sets a time delay control strategy to dynamically adjust the network transmission delay, and improves the user experience.

Description

[0001] This application is a divisional application of a Chinese patent application submitted to the China Patent Office on September 06, 2012, with the application number 201280001381.4 and the application title "Method for controlling network transmission delay, service quality control entity and communication equipment". The entire contents are incorporated by reference in this application. technical field [0002] The present application relates to the communication field, in particular to a method for controlling network transmission delay in the communication field, a quality of service control entity and a communication device. Background technique [0003] The communication network is gradually evolving from a circuit switching (CS) network to a packet switching (PS) network carried by an Internet protocol (IP). When IP networks provide carrier-class services, a key issue is to consider end-to-end quality of service (QoS) issues to meet user requirements for communic...

Problems solved by technology

For example, the application server requires a maximum delay of 120ms, PCRF generates QCI = 1, and the corresponding maximum delay is 100ms, but in fact the delay between the application server and PCEF is 40ms, so this QoS policy cannot meet the application layer's time delay. delay demand

[0006] On the other hand, once the QoS policy is generated, it is considered that the network can meet the delay requirements of the application layer. In fact, due to reasons such as user mobility and network status, the initial QoS policy may meet the delay requirements, but subsequent Due to network switching or wireless resource congestion, the network cannot meet the transmission delay requirements of service flows, resulting in poor user experience
