Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] The embodiment of the present invention is based on the PacketCable2.0 standard such as figure 1 As shown in the architecture, when the architecture is applied to the NAT scenario, the access-border gateway function (access-border gateway function, A-BGF) network element is introduced, and by connecting it with the proxy-call session control function (proxy-call session control function, P-CSCF) network elements are connected to complete the NAT traversal of signaling streams and media streams during the communication process, so as to further realize the QoS guarantee of communication servi...

Abstract

The present invention is applicable to the field of network communications, and provides a method for guaranteeing QoS of a communication service in a NAT scenario, including: when a user equipment initiates a communication request, controlling an A-BGF network element to generate proxy SDP information according to calling party SDP information, and replacing the calling party SDP information with the proxy SDP information to establish a connection between the user equipment and a called party; after a connection between both communication parties is successful, instructing a PCRF network element to perform QoS resource reservation; and receiving a NAT-translated-to IP address and a port of the user equipment from the A-BGF network element, and instructing the PCRF network element to update source address information for the QoS resource reservation to the NAT-translated-to IP address and the port of the user equipment. The present invention achieves QoS guarantee of a communication service in a NAT scenario without imposing any special interface requirement on the user equipment.

Description

technical field [0001] The invention belongs to the field of network communication, and in particular relates to a communication service QoS guarantee method, device and system in a NAT scene. Background technique [0002] The existing hybrid fiber-coaxial (HFC) network provides triple play services by combining the IP multimedia subsystem (IMS). At this time, there will be network Telephone (voice over internet protocol, VOIP) services, video conferencing services, Internet services and interactive TV services and other related data (media streams) are transmitted, and when the network is congested, real-time requirements for VOIP and video conferencing are required Quality of service (QoS) guarantee for high communication services. As one of the QoS guarantee mechanisms in the network, QoS resource reservation, on the premise that the QoS requirements of the media streams of both parties and the media stream coding scheme are clarified, the calling party starts to establi...
