Problems solved by technology

[0012] However, in the current WiMax network and IMS network convergence scenario, there is no end-to-end Qos signaling interaction method between the WiMax network and the IMS network, which leads to the inability to realize the end-to-end Qos service in the WiMax network and IMS network convergence scenario

Embodiment Construction

[0157] The present invention is further illustrated below by means of the accompanying drawings and specific embodiments.

[0158] The present invention provides an end-to-end Qos signaling interaction method suitable for the global microwave access interoperability WiMax network and IMS network fusion scene. Figure 4 It is a flowchart of the method of the present invention. see Figure 4 , the method includes:

[0159] Step 401, the user terminal establishes a preset service flow in the WiMax network. The user terminal can access the WiMax network only after the preset service flow is established, and this process only occurs once after the user terminal passes the authentication process.

[0160] This step is the first stage of the method of the present invention, and is the basis for the user terminal to establish an application layer session (AF Session) with the IMS network through the WiMax network in the second stage. The basis of end-to-end Qos signaling interacti...

Abstract

A method for interacting with quality of service (Qos) signaling, suitable for the interaction of end-to-end Qos signaling in the convergence scenario of a Worldwide Interoperability for Microwave Access (WiMax) network and an IP Multimedia Subsystem (IMS) network, characterized in In that, the method includes: A, the user terminal sets up a preset service flow in the WiMax network; B, making the user terminal obtain the Qos policy authorization of the Qos policy decision unit (PDF) in the IMS network about the user terminal service flow through the application layer session C, the user terminal executes the Qos signaling interaction process of the end-to-end service flow on the preset service flow; When interacting between the WiMax network and the PDF, first convert the Qos signaling into a format accepted by the other party, and then send it to the other party. The present invention can realize the end-to-end Qos service in the scenario where the WiMax network and the IMS network are integrated.

Description

technical field [0001] The present invention relates to a signaling interaction technology for network convergence in a communication system, in particular to end-to-end Quality of Service (Qos) signaling in a network convergence scenario of Worldwide Interoperability for Microwave Access (WiMAX) and IP Multimedia Subsystem (IMS) interaction method. Background technique [0002] WiMAX network is a solution provided for wireless metropolitan area network access technology or wide area wireless network. figure 1 It is a structural diagram for solving Qos in the existing WiMAX network. see figure 1 , the WiMAX Qos structure includes: [0003] Subscriber Terminal (SS). [0004] A Service Flow Management (SFM, A Service Flow Management) is responsible for establishing user service flows and allocating wireless resources for the service flows, etc. This function exists in the Access Service Network (ASN, Access Service Network) of WiMAX. [0005] A Service Flow Authorization ...
