End-to-end quality of service dynamic management system and method under heterogeneous network interconnecting scene

Abstract

The invention relates to a system for dynamic management of end-to-end quality of service (QoS) under interconnection of heterogeneous networks and a method thereof. The system comprises a public core network and at least two underlay networks. A strategy decision-making device is arranged in the public core network, a strategy executing device is arranged in each underlay network, and the strategy decision-making device is connected with the strategy executing devices via a Diameter protocol. Interaction of QoS information between the strategy decision-making device and the strategy executing devices is realized by defining an underlay construction process and an underlay message deletion process; and the strategy executing devices map the QoS information as the QoS parameters for a local underlay for executing the resource reservation and gate control functions of the local underlay. The core network can make a QoS strategy based on subscriber information and a subscriber's service resource request and then accurately transmit the QoS strategy to different stages of underlay network media streams in time to form links, so as to realize QoS control on different stages of underlay links, respectively, thereby improving the guarantee capacity of the subscriber and the network on the QoS.

Description

[technical field] [0001] The present invention relates to a system and method for realizing end-to-end quality of service (Quality of Service, QoS for short) dynamic management in a heterogeneous network interconnection scenario, which is applicable to the existing microwave access interoperability network (World Interoperability for Microwave Access, abbreviated as WiMAX), and a wireless local area network (Wireless Local Access Network, abbreviated as WLAN) are connected to a heterogeneous network of a mobile core network. [Background technique] [0002] A good quality of service (QoS) management system first needs to dynamically determine the quality of service policy based on the subscription information of users and services and user service requests, so as to meet the service quality requirements of different users and services and realize differentiated services. On the other hand, network operators try to avoid allocating too many resources to users and services that...

AI Technical Summary

Problems solved by technology

[0003] However, in some heterogeneous network interconnection scenarios, due to the diversification of access networks and the loosely coupled relationship between access networks and core networks, dynamic control of end-to-end service quality is difficult to achieve

[0004] Take WiMAX network access to mobile core network through I-WLAN (Interworking-WLAN, a specific architecture for WiMAX and mobile network interconnection) as an example, although the international 3GPP standardization organization and WiMAX standardization organization for mobile networks have proposed some services Quality of Service (QoS) management technology standards, but these technologies are not yet able to achieve end-to-end dynamic service quality management goals in the scenario where WiMAX and mobile core networks are interconnected
