Description

Dynamic service flow processing method and system

The present invention relates to the field of communications, and in particular, to a method and system for processing a dynamic traffic flow. BACKGROUND OF THE INVENTION Worldwide Interoperability for Microwave Access (WiMAX) technology is a broadband wireless access standard based on the 802.16 protocol, which provides high-speed connectivity to the Internet. Different from the 3rd Generation (3G) network, the WiMAX network completely uses the Internet Protocol (IP) packet switching technology instead of providing voice-oriented circuit switching. 1 is a schematic diagram of a WiMAX network reference model in the related art. As shown in FIG. 1, an Access Service Network (ASN) i or implemented functions include: connection with a WiMAX terminal, authentication, and 4 MANN. Fee messaging, discovery and selection of service networks, provision of relay functions for establishing Internet connections with WiMAX terminals, management of wireless air interface resources, tunnel establishment and management between access service networks and connected service networks; connection service network (Connect Service) The network (referred to as CSN) domain (showing the CSN domain of the visited domain and the home domain in FIG. 1) implements functions including: user Internet address allocation and access, authentication and authorization charging agent or service, and policy based on user system parameters. And the license control, the tunnel establishment and management between the access service network and the connected service network, the roaming tunnel between the connected service networks, and the mobility management. Currently, WiMAX systems can carry a variety of services, such as: voice, video, Hyper Text Transport Protocol (HTTP) and e-mail, and due to the quality of each business (Quality of Service) The requirements for QoS are different. Therefore, WiMAX networks need to use different service flows to provide different service data for the same mobile terminal. The service flow is divided according to packet information such as source address, destination address, port number, and protocol number, and a QoS parameter is specified for each service flow to provide corresponding service quality for different services. In addition, the system also sets a Service Flow Identification (SFID) for each service flow to indicate the service flow and corresponding QoS parameters. In an actual application, you can do the following for a business flow:

(1) create an operation (create;), for example: When there is a new application requirement, the system can create a new business flow;

(2) Approved operation (Admit), for example: The system determines whether it can meet the QoS parameter requirements of a certain service flow according to the actual resource usage;

(3) Activated operation refers to the process of putting a business flow into use after it has been approved;

(4) Modifying (Modify), which can be performed when the QoS parameters of a certain service flow cannot meet the current application requirements, so as to tamper and adjust the QoS parameters;

(5) The delete operation (delete) can be used to delete the service flow supporting the application when an application ends. 2 is a schematic diagram of a QoS logical model of a WiMAX network in the related art. As shown in FIG. 2, in a WIMAX system, a network node that provides a service flow for a user mainly includes: a Service Flow Management (SFM) entity. Service i3⁄44 Service Flow Authorization (SFA) entity and Police Function (PF) entity. The SFM entity is configured on the base station side, and can perform related service flow operations according to the local radio resource situation; the SFA entity includes the service flow 4 (Severage SFA, SFA monthly service point) entity and the service flow. 4: The SFA entity can perform the approval operation on the service flow according to the local policy; the PF entity is located on the CSN side, and is used to save the user information and provide the QoS policy of the service flow. . 3 is a schematic diagram of the operation of the WiMAX network service flow in the related art. As shown in FIG. 3, the service flow operation in the WiMAX network includes the following steps (step S302 - step S312): Step S302, the user access authentication 4 Manpower process In the authentication, Authorization and Accounting (AAA) ^! The QoS parameter information of the user subscription is sent to the authenticator Authenticator, and the SFA 4 seedling entity (ie, Authenticator) sends a resource reservation request (RR_Req) message to the SFA service point entity after receiving the contracted QoS information, and The QoS parameter information is carried in the RR_Req message; Step S304, the SFA service point entity receives the resource reservation request message, sends a data channel request message to the SFM entity, and carries the QoS parameter information therein; Step S306, the SFM entity receives the data channel Requesting a message, obtaining QoS parameter information, and judging whether to accept the data channel request according to the available radio resource status; The SFM entity sends a radio resource request message to the terminal. Step S308: The terminal receives the radio resource request message, rejects or accepts the resource request according to the 802.16e protocol, and sends a radio resource response message to the SFM entity. Step S310, the SFM entity sends the SFA entity to the SFA. The service point entity sends a data channel response message, and carries information confirming the current resource reservation therein; Step S312, the service SFA entity receives the data channel response message from the SFM entity, and sends a resource reservation response message to the SFA anchor entity, And carry information confirming the current resource reservation. In order to ensure the QoS of WiMAX dynamic services, in the WiMAX R1.5 version, the third quarter of the 3rd Generation Partnership Project (3GPP) standard organization proposed the policy charging control architecture. The PF entity is taken by the Policy and Charging Rules Function (PCRF) entity. The Policy and Charging Enforcement Function (PCEF) entity logic function is set by the SFA. The Anchor SFA is implemented by the entity. At the same time, the session modification process triggered by the PCRF entity and the policy enforcement entity PCEF (SFA Anchor Entity) is defined, which is respectively applied to the dynamic service flow creation requested by the Application Function (AF) entity. 'Troubled and terminal/base station request for WiMAX dynamic service flow creation 爹' tampering process. In the current WiMAX specification version, a pre-made service flow is defined, which is triggered by the Anchor SFA entity after the normal network registration process of the user is completed. Since the service flow creation process is attached to the certification business process, it is pre-created by the system before the user service starts, and can only be initiated by the Access Gate Way (AGW for short). Considering the requirements of dynamic services, for example: For users who use QQ services, they first chat through text transmission. If you want to perform video voice chat, the pre-made service flow QoS that is not pre-created by the system cannot meet the user's needs, then the user cannot use the business. Therefore, WiMAX needs to support the processing of dynamic services. Considering the two situations of resource requests triggered by AF and terminals, it is necessary to increase the power within the WiMAX network. The process of dynamically changing the business flow creation by the UE.

As shown in FIG. 5, the process of creating/modifying a dynamic service flow of a UE includes the following processing (Step S502 - Step S518) And, in step S502, the user sends an air interface resource request message to the SFM entity, and carries the QoS parameter information requested by the user in the air interface resource request message. Step S504: After receiving the user air interface resource request message, the SFM entity first performs admission control. That is, the current air interface resource status is compared with the QoS parameter in the user service flow request; specifically, the SFM entity obtains the QoS parameter information of the terminal requirement from the resource request message; the QoS of the SFM entity according to the current air interface resource status and the terminal requirement If the admission control is passed, the SFM entity checks whether Whether you need to create a new data channel, ie, judge Whether the QoS condition of the data channel has been created to meet the QoS parameters in the user service flow request; if the current data channel QoS can meet the service requirement, the SFM sends a data channel tampering request message to the Serving SFA entity (Path_Modification_Req) If the QoS of the current data channel cannot meet the service requirement, the SFM sends a data channel creation request message (Path_Reg_Req); that is, the data channel request message in the above step S402; Step S506, the Serving SFA entity receives the SFM entity. After the data channel request message is sent, the resource reservation request message is sent to the Anchor SFA entity, and the QoS parameter of the user service request is carried therein; that is, the above step S404; Step S508, the Anchor SFA entity receives the resource reservation request message from the Serving SFA entity; in the scenario where the PCC is responsible for policy control, the Anchor SFA (A-PCEF) requests the policy decision from the PCRF; in the non-PCC scenario, the ASN may After the authentication, the QoS template, the ASN load status, and the user service flow QoS request obtained from the AAA directly make local policy decisions; after that, the Anchor SFA entity obtains the result of the policy decision, and based on the policy decision result Retaining a resource, and sending a resource reservation response message to the Serving SFA entity, where the resource reservation response message carries the determined quality of service parameter information and the service flow identifier; and in step S510, the Serving SFA entity attaches the resource reservation response message In the data channel response message, the message (Path_Reg_Rsp) or the tampering data channel (Path_Modification_Rsp) message is sent to the SFM entity; that is, the above step S406; in the following processing, it can be divided into two cases. They are: Case 1, according to the channel request message is data communication Create a request message; Case 2, the data channel request message is a data channel modification request message. The following two cases are described: Case 1: In the case that the data channel request message is a data channel creation request message, the Serving SFA entity The data channel response message sent by the SFM entity creates a response message for the data channel, where the data channel creation response message carries the determined quality of service parameter information, the service flow identifier, and the data channel identifier. In the second case, the data channel request message is data. In the case of the channel tampering request message, the data channel response message sent by the Serving SFA entity to the SFM entity is a data channel modification response message, where the data channel modification response message carries the determined quality of service parameter information, the service flow identifier, and the data. Channel identifier; Step S512, the SFM entity receives the data channel response message, obtains the determined quality of service parameter information, and assigns a resource to the service flow; subsequently, the SFM passes the user service request policy decision result through the air interface resource response Sending a message to the UE (ie, the terminal), and carrying the determined QoS parameter information, the service flow identifier, and the data channel identifier in the air interface resource response message; Step S514, the UE sends an air interface resource confirmation message to confirm the resource request; Thereafter, the SFM entity receives the air interface resource acknowledgment message from the terminal. Step S516, after receiving the air interface resource acknowledgment message, the SFM entity confirms the resource reservation according to the type of the data channel request message sent in step S504. Determining the type of the data channel acknowledgement message in the above step S408; for example: if the message sent in step S504 The type is a data channel tampering request message ( Path_Modification - Req ), and the SFM entity sends a data channel tampering confirmation message ( Path_Modification - Ack ) to the Serving SFA entity. If a request message (Path_Reg_Req) is created for the data channel, the SFM entity sends a data channel creation confirmation message (Path_Reg_Ack) to the Serving SFA entity; that is, the above step S408; Step S518, the Serving SFA entity receives After the data channel acknowledgement message to the SFM entity, the resource reservation confirmation message is sent to the Anchor SFA entity; that is, the above step S410;

The anchor SFA entity receives the resource reservation confirmation message. At this point, the user service resource request action is basically completed, and the dynamic service flow carrying the user service has been successfully processed in the ASN. In this embodiment, after the interaction between the service flow management entity, the SFA service point entity, and the SFA anchor entity is performed by the establishment of the dynamic service flow triggered by the user side, the resource is assigned by the service flow management entity.
