Description

A kind of business flow establishing method and system
Technical field
The present invention relates to the communications field, relate more specifically to business flow establishing method and system in interoperability (WiMAX) system of a kind of inserting of microwave whole world.
Background technology
Along with the extensive use of the portable terminal development of demand and wireless technology, and inserting of microwave whole world interoperability (Worldwide Interoperability for Microwave Access, WiMAX) development of technology is more and swifter and more violent, and prospect is more and more wide.
See also accompanying drawing 1 and accompanying drawing 2, simply introduce the network architecture system of WiMAX:
(World Interoperability for Microwave Access, WiMax is based on the wireless metropolitan area network technology of IEEE802.16 standard for WiMAX.World Interoperability for Microwave Access is called for short WiMAX) network reference model such as Fig. 1.(the Connectivity Service Network of CSN wherein, be called for short CSN) be connection service network, MS/SS (Mobile Station/Subscriber Station is called for short MS/SS) is a portable terminal, ASN (Access Service Network, access service network is called for short ASN) be the set of the corresponding message flow of physical entity relevant in the WiMAX network system with access service.Connection between the ASN is by the R4 mouth.Again can refinement in ASN inside, as shown in Figure 2, AGW (ASN Gateway wherein, the ASN aggregation gateway, also can abbreviate ASN-GW as) and BS (Base Station, base station) connect by internal interface R6 mouth, the R6 mouth is made of a series of control and load plane agreement.Further segmentation, ASN-GW comprises Certificate Authority physical entity (Authenticator) again, channel management physical entity (DPF) location management physical entity (PC/LR), these three physical entities can be in same physical entities, also can be on different physical entities.
Functions such as BS mainly provides RRM, power measurement and control, the compression of the data of eating dishes without rice or wine and encryption; Authenticator mainly provides authentication among the ASN-GW, the function of authorizing and chargeing, and DPF mainly provides channel management, assists to set up between high level and the MS 3 layers and function such as is connected, and PC/LR mainly provides location management, functions such as paging; CSN mainly comprises home agent (Home Agent, HA), DHCP (Dynamic Host Configuration Protocol, DHCP) server, and authenticated/authorized/charging (Authentication-Authorization-Accounting, AAA) physical entity such as server mainly provides charging, authentication, authorize functions such as distributing IP address, internet service access.
The user is in access procedure, can set up Business Stream (also can be called data channel or passage) between BS and the AGW, Business Stream has two kinds: ISF (Initial Service Flow, initial service flow) and PSF (Prepare Service Flow, reserved service flow).The user is in access procedure, and what at first set up is ISF stream, sets up PSF stream then.
Three layers signaling (as the DHCP signaling) must transmission in ISF stream.If user's ISF stream is set up failure, user's access is failure just.Specific business (as voice) can be walked PSF stream.The user sets up many Business Streams just can make different business walk different PSF stream (as video, voice etc.), guarantees carrying out smoothly of every kind of business.
Below in conjunction with this structure system the flow process of existing switching in the present agreement is carried out the specific aim introduction.
All handoff scenario all are based on user service flow and set up and to carry out on the basis finish in the prior protocols, and the user can switch in setting up the process of Business Stream in the environment of reality.Describe below in conjunction with the flow process problem that occurs that switches of setting up of this structure system existing Business Stream in the present agreement.
Fig. 3 for the DPF in the existing protocol and Authenticator on different physical entities Business Stream set up flow process.
301:Authenticator sends resource reservation request message according to the information of the Business Stream of authorizing to DPF, and request resource is reserved;
302:DPF is according to resource reservation request message, and BS, the foundation of request channel and resource reservation are given in the request of setting up of structure passage;
303:BS sets up request to the MS sendaisle;
304:MS sets up response to the BS sendaisle after receiving that passage is set up request;
The 305:BS sendaisle is set up response and is given DPF;
306:DPF sends successful resource reservation and responds to Authenticator after receiving the passage foundation response of success;
The 307:DPF sendaisle is set up and is confirmed to give BS;
308:Authenticator is receiving that resource reservation response back sends resource reservation and confirms to DPF.
Fig. 4 for the DPF in the existing protocol and Authenticator on same physical entity Business Stream set up flow process.
BS, the foundation of request channel and resource reservation are given in the request of setting up of 401:AGW sendaisle;
402:BS sets up request to the MS sendaisle;
403:MS sets up response to the BS sendaisle after receiving that passage is set up request;
The 404:BS sendaisle is set up response and is given AGW;
After 405:AGW received the passage foundation response of success, sendaisle was set up and is confirmed to give BS.
In scene shown in Figure 3, DPF is with Authenticator on different physical entities the time:
Flow through in the journey setting up ISF, if before MS receives the passage foundation request of BS, switch, MS can't set up response to BS by sendaisle, DPF will can not receive or receive the passage foundation response of failure this moment, DPF will send the resource reservation response of failure to Authenticator, can think Authenticator at this moment user's access failure, discharge all resources of user, and the user was not access failure but switching took place this moment.
In the process of setting up PSF stream, if DPF MS before receiving the resource reservation request message of Authenticator switches or BS receives that the preceding MS of passage foundation request switches, this moment, BS or DPF handled switching flow, can't handle the request of setting up Business Stream, the response that this moment, BS or DPF can send failure causes PSF stream to set up failure to DPF or Authenticator.If also have this moment PSF stream not set up, in the process of setting up subsequent P SF stream, do not finish if switch, PSF stream all can be set up failure.
In scene shown in Figure 4, DPF is with Authenticator on identical physical entity the time:
Flow through in the journey setting up ISF, if before MS receives the passage foundation request of BS, switch, MS can't set up response message to BS by sendaisle, AGW will can not receive or receive the 404 passages foundation response of failure this moment, can think AGW at this moment user's access failure, discharge all resources of user, and the user is not access failure but switching has taken place at this moment;
In setting up the process of PSF stream, AGW before sending 401 passages to set up request or BS receive 401 passages set up request before MS switch, this moment, BS or AGW handling switching flow, can't handle the request of setting up Business Stream, caused PSF stream to be set up and failed.If also have this moment PSF stream not set up, in the process of setting up subsequent P SF stream, do not finish if switch, PSF stream all can be set up failure.
Two problems of above-mentioned existence can cause following problem:
1. setting up switches in the process of ISF stream causes access failure by the agreement flow processing, causes AGW to discharge the user, and the user has only to insert again and can be connected on the network, and the access success rate and the user that influences the user experience.
2. set up in the process of PSF stream and switch, can cause the PSF stream of current foundation to set up failure, make that the specific QoS of survice (service quality) based on this PSF stream can't be guaranteed, influence user's online quality.
