Description
Technical field
The present invention relates to the communications field, in particular to a kind of implementation method and system of service flow modification.
Background technology
Micro-wave access global inter communication technology (Worldwide Interoperability forMicrowave Access abbreviates WiMAX as) is a kind of broadband wireless access standard, and this standard provides towards the high speed of the Internet to connect based on 802.16 agreements.Simultaneously, multiple business can be carried in the WiMAX system, for example: voice, video, HTTP and E-mail etc. since each business to service quality require differently, carry different business datums so the different Business Stream of WiMAX network using is same portable terminal.Wherein, Business Stream is divided according to grouping information such as source address, destination address, port numbers and protocol numbers, and be each Business Stream appointment service quality (Quality of Service abbreviates QoS as) parameter, so that the service quality of correspondence is provided for different business.In addition, system also sets a traffic stream identifier (Service Flow Identification abbreviates SFID as) for each Business Stream, is used to indicate this Business Stream and corresponding qos parameter.
In actual applications, can carry out following operation at Business Stream:
(1) creates (create).For example: when having new application demand, system can new Business Stream of create.
(2) approval (Admit).For example: can system determine self satisfy the qos parameter requirement of certain Business Stream according to the resource operating position of reality.
(3) activate (Activate).After activation is meant that certain Business Stream obtains approval, with its process that comes into operation.
(4) revise (Modify).When can can't satisfying the current application demand at the qos parameter of certain Business Stream, this operation carries out, so that qos parameter is made amendment and adjusted.
(5) deletion (delete).Certain is used when finishing, and need will support the Business Stream deletion of this application.
Fig. 1 is the block diagram according to the WiMAX network QoS logical architecture of correlation technique.
In the WIMAX system, for providing Business Stream network operating node, the user mainly comprises: service flow management module (Service Flow Management, abbreviate SFM as), service flow authorization module (Service Flow Authorization, abbreviate SFA as) and policing feature module (Policy Function abbreviates PF as).Wherein, SFM is positioned at base station side (access business network), can carry out access control and Business Stream associative operation according to the Radio Resource situation of this locality.SFA comprises service flow authorization service point (Serving SFA) and service flow authorization anchor point (Anchor SFA) again, and SFA can carry out the approval operation to Business Stream according to the user signing contract information that issues among local policy and the AAA (authentication and authorization charging functional module).PF is positioned at and connects business network (Connect Service Network abbreviates CSN as), can be used to preserve user profile and be responsible for providing the qos policy of Business Stream to make a strategic decision in home network service carrier network or visited network service carrier network.
Fig. 2 is the schematic diagram according to Business Stream operating process in the WiMAX network of correlation technique.MS among Fig. 2 is the terminal use, and SFM is the service flow management module, Serving SFA service flow authorization service point, and Anchor SFA is the service flow authorization anchor point, as shown in Figure 2, this method may further comprise the steps:
Step 1, in the access authentication of user licensing process, AAA is issued to authenticator (authenticator) with user's approval authority of contract signature qos-related information.After the user network registration is finished, service flow authorization anchor point (being authenticator) sends RR_Req (resource reservation request) message that comprises this qos parameter information to the service flow authorization service point, simultaneously, the SFID as this desire establishment Business Stream of sign also is contained in this resource reservation request message;
Step 2, service flow authorization service point are contained in this resource reservation request packets of information in DP (data channel) message and are sent to SFM.Comprise two parts of resource reservation request information and data channel descriptor in this data channel message;
Step 3, whether SFM decides this request should be accepted based on qos parameter information in the data channel message and available radio resources situation; If accept, SFM will send a Radio Resource message to portable terminal.
A kind of possible scene is (scenario A): suppose to have comprised in the resource reservation request message in step 1 resource degradation sign indicating number (Reduced Resource Code abbreviates RRC as), and hypothesis SFM finds the current available resources deficiency of eating dishes without rice or wine.Then SFM can not refuse this resource reservation request yet, and just SFM can be revised as the qos parameter that comprises in this Radio Resource message current available interface-free resources QoS;
Step 4, portable terminal is handled this Radio Resource message according to the 802.16e agreement;
Step 5, SFM is according to the result of UE in SFM and the step 4 in the step 3, feed back this time resource reservation result to the service flow authorization service point, finish by the data channel response message, wherein comprise resource reservation response message (only comprising the result of resource reservation response and the sign SFID of this Business Stream in this resource reservation response message) and data channel descriptor.
Be under the situation of example with the scenario A, also will comprising qos parameter (QoSParameters) information of the current SFM of sign in this resource reservation response message for the usable radio resources situation of this Business Stream reservation;
Step 6, service flow authorization service point send the resource reservation response message to the service flow authorization anchor point after the response that receives SFM; The part of this resource reservation response message data channel response message that to be the service flow authorization service point receive from SFM;
Step 7, the service flow authorization service point sends the data channel acknowledge message to SFM, only comprises the SFID identification information of Business Stream in the resource reservation acknowledge message wherein;
Step 8, the service flow authorization anchor point sends the resource reservation acknowledge message to the service flow authorization service point, wherein only comprises the SFID identification information of Business Stream.
Can draw by above-mentioned Business Stream visioning procedure, when the radio open resource situation can satisfy the signatory qos requirement of this Business Stream, because the modification that SFM can not initiate Business Stream makes it the demand that reaches signatory with staging business stream QoS, therefore service flow modification process can not adapt to this variation under the situation of network state real time altering, thereby can not satisfy user's QoS demand.
