Embodiment Construction

[0042] A SIP application-oriented service flow management method provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] In one embodiment of the present invention, a method for automatically providing service flow management for multimedia communication service users in real time under a heterogeneous network environment is provided. Multimedia communication services for video data transmission. figure 1 Show the specific network topology environment, such as figure 1 As shown, user A accesses the network (such as WLAN) wirelessly, user B accesses the network wirelessly (assumed to be WLAN), and user C accesses the network via LAN. User A transmits audio, video or file data with users B and C through the core IP network. A solid line indicates a wired link being connected, and a lightning symbol indicates a wireless link. All three users of A, B and C complete the establishment and...

Abstract

The invention provides an SIP-application-oriented traffic-flow managing method, the user logs in a local SIP agent server and sends a PUBLISH message to the SIP agent server; the local SIP user initiates or receives a communication service request, parses an SIP-service request INVITE message, inquires about the PUBLISH message, and sends a service-initiating notice to a network-level data-processing unit; the local SIP user captures a data packet sent to the corresponding user on the network level, initiates a notice according to the service, maintains a traffic-flow information managing list of the user on the basis of the SIP address of the user, establishes a corresponding data-packet queue passage for each traffic-flow communication link of each user, and schedules the data-packet queue. The invention adopts a new service notifying mechanism aiming at typical SIP applications, takes the SIP address of the user as the keyword to manage the traffic-flow resource, deploys the bandwidth of the current traffic-flow in real time according to the change of network accessing state of the user with the reference of the service demand grade information of the user, and effectively improves the utilization ratio of the network resources and the work efficiency of the current network.

Description

technical field [0001] The present invention relates to the technical field of Internet and multimedia communication, and more specifically, the present invention relates to a SIP application-oriented service flow management method under the IPv4 / IPv6 network environment. Background technique [0002] At present, network technology has entered a new era of rapid development, and the Internet, telecommunication networks, and radio and television networks are increasingly integrated. The next-generation network will definitely be an all-IP network that integrates fixed and mobile networks. At the same time, various new services based on next-generation networks are constantly emerging, requiring support for various multimedia services such as voice, image, and video. [0003] Session Initiation Protocol (Session Initiation Protocol, SIP) is currently one of the most studied protocols related to next-generation networks. Based on SIP, multimedia sessions can be easily establish...
