Embodiment 1

[0084] According to an embodiment of the present invention, an Authentication Authorization Accounting function entity (AAA) 520 is provided. Such as Figure 5 As shown, the AAA 520 is used to store a preset dynamic service flow template, where the dynamic service flow template includes QoS parameter information for different media flow types. Moreover, the definition of the dynamic business flow template in the Radius message can refer to Figure 4 And Table 1 in the method embodiment.

[0085] During the initial access authentication and authorization process of the mobile terminal, the AAA 520 sends the dynamic service flow template to the Anchor SFA 540 for the Anchor SFA 540 to make a policy decision on the service flow creation / modification request message sent by the terminal.

[0086] Wherein, the specific processing of the Anchor SFA 540 to make a policy decision on the request message of the terminal has been described in detail in the above-mentioned method embodi...

Embodiment 2

[0089] According to the embodiment of the present invention, a service flow authorization anchor point 540 is provided, which is located in the access service network 54 and is used to ensure dynamic service QoS according to the dynamic service flow template preset in AAA. Among them, Anchor SFA 540 can refer to Figure 5 as well as figure 2 .

[0090] The Anchor SFA 540 is used to receive service flow creation / modification request messages, and make policy decisions on the mobile terminal according to the current ASN load status, the QoS information requested by the mobile terminal carried in the request message, and the dynamic service flow template.

[0091] Such as Figure 6 As shown, Anchor SFA can further include:

[0092] The acquiring module 60 is configured to acquire the minimum bandwidth request of the QoS information in the service flow creation / modification request message.

[0093] The judging module 62 is used to compare the current ASN load status (cb) and...

Abstract

The invention provides a QoS ensuring method of a dynamic service, a system and AAA and Anchor SFA, comprising: arranging a dynamic service flow module in an authentication authorization charging functional entity, wherein the dynamic service flow module includes service quantity parameter information corresponding to different medium flow types; transmitting the dynamic service flow module to a service flow authorization anchor point by the authentication authorization charging functional entity when a mobile terminal is initially accessed to the authentication authorization; receiving theservice flow building / modifying request information by the service flow authorization anchor point, and performing strategy decision-making according to load accessed to the service network, service quality information requested by the mobile terminal carried in the service flow building / modifying request information. According to the process, QoS of the dynamic service is ensured under network environment of non-strategy charging control.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a quality of service (Quality Of Service, referred to as QoS) guarantee method and system for dynamic services, an Authentication Authorization Accounting function entity (Authentication Authorization Accounting, referred to as AAA) and a service flow Authorization anchor (Anchor Service Flow Authorization, referred to as Anchor SFA). Background technique [0002] The Worldwide Interoperability for Microwave Access (WiMAX for short) technology is a broadband wireless access standard, which is based on the 802.16 protocol and can provide high-speed Internet-oriented connections. figure 1 A schematic diagram of the WiMAX network reference model, such as figure 1 As shown, the WiMAX network mainly includes: [0003] Access Service Network (ASN for short), which is used to connect with WiMAX terminals, transmit authentication, authorization and accounting messages, di...
