Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.
Fig. 1 is for guaranteeing the method principle schematic of applied business QoS in the EVDO of the present invention system, and is as shown in Figure 1, among the present invention; Professional for the upper layer application between AT (accessing terminal Access Terminal) and the AppServer, core-network side is discerned service message through the DPI module; And the message of different application type of service identified, identify through different filling patterns among Fig. 1, after wireless side is received the applied business message; The professional message of different application is carried out the sorting flow statistics; Thereby identify the current main applied business of user, promptly main applied business type is the type of service of left oblique line for filling pattern in the present embodiment.For this main applied business, wireless side is mapped to corresponding QoS resource allocation policy, and then carries out resource allocation.Thereby comprise that in wireless side eat dishes without rice or wine (RLP master's connection) obtains to satisfy the transmission characteristic of upper layer application business demand, makes the user who accesses terminal when carrying out the QoS applied business, obtain favorable experience and perception.Among Fig. 1, each character implication is following: PCF:Packet Control Function, Packet Control Function module; AppServer:Application Server, application server; Router: router; RLP:Radio Link Protocol, radio link protocol.
Fig. 2 is for guaranteeing the method flow sketch map of applied business QoS in the EVDO of the present invention system, and is as shown in Figure 2, guarantees that the method for applied business QoS specifically comprises the steps: in the EVDO of the present invention system
Step 201, wireless side receive user's applied business message that core-network side is sent; Header identifies service message corresponding upper applied business type by core-network side; Like file download, voice and video, web page browsing etc.; Wireless side is carried out traffic statistics according to the classification of upper layer application type of service, identifies the current main applied business type of user thereby detect.Specifically comprise:
(1) sign is carried: core-network side is discerned the message of user's different application type of service, and is carried to wireless side through message identification through DPI (Deep Pakcet Inspect, deep message identification) function.
(2) traffic statistics: wireless side receives the applied business message that core-network side is sent, and passes through the flow of the various applied business of message identification statistic of classification active user.
(3) the professional detection: wireless side is according to the current main applied business type of judges with the traffic statistics data; Main applied business type definition is professional for the upper layer application that the user mainly uses in current slot; If being QoS, main applied business type uses; Professional like voice and video, then wireless side can promote the experience perception of this type of user business greatly through the QoS resource allocation policy of configuration.The foundation that main applied business is weighed is the flow of user's different business, provides the computational discrimination method of quantification.
Owing in once connecting, possibly have variation with householder's applied business type; In order to dynamically update user's main applied business type; Set professional sense cycle; Then in each professional sense cycle, wireless side is calculated balance to all applied business in this cycle according to service traffics, confirms the main applied business type that the active user uses in current period.Change when detecting, then will carry out Internet resources and redistribute/upgrade according to the new QoS resource allocation policy of correspondence with householder's applied business type.
The deficiency that periodic traffic detects is to exist certain detection hysteresis quality; For the stable user who continues to carry out applied business; This detection is to be similar to accurately; But for carrying out the professional user's (being typically the cellphone subscriber) of sudden low discharge, the hysteresis quality that this periodicity detects possibly cause also can not detecting in wireless side user's main applied business type, and the user is with regard to the business that has been through with.
In order the user who carries out sudden low discharge business to be realized the assurance of QoS; Also in order when wireless side is received QoS applied business type message for the first time, to carry out resource allocation in view of the above to the stable user who continues to carry out applied business; In the embodiment of the invention; When wireless side receives the message of QoS applied business type for the first time, judge that directly active user's main applied business type is the pairing applied business type of this message that receives for the first time, and carry out Resource Allocation in Networks in view of the above.
Thereby in the embodiment of the invention, the inventive method comprises two stages: 1, when receiving QoS applied business type message for the first time, judge that directly active user's main applied business type is the pairing applied business type of this message that receives for the first time; 2, when receiving QoS applied business message the non-first time, detect, in each professional sense cycle, obtain user's main applied business type according to traffic statistics according to professional sense cycle.
For in the professional sense cycle with the calculating of householder's applied business type, the detection algorithm below having proposed in the embodiment of the invention:
At first, it is following to define each meaning of parameters:
Tn: the total flow of type of service A current detection cycle n (is unit with the byte);
Tsn: the total flow of all type of service current detection cycle n (is unit with the byte);
Rn: flow accounting in the type of service A current detection cycle n;
Sn: the flow accounting of type of service A current period n after the filtering;
S N-1: the flow accounting of the last sense cycle n-1 of type of service A after the filtering;
τ: filtering constant detection time, τ are positive number, are convenience of calculation, and it is good getting natural number.
With householder's applied business type detection algorithm:
If current is first sense cycle, then Sn=Rn;
Otherwise, Sn=(S N-1+ Rn* (τ-1))/τ;
Wherein, Rn=Tn/Tsn*100%.
The purpose of using filtering constant tau detection time is to carry out smoothly detecting recognition result, thereby avoids in a plurality of continuous professional sense cycle, detecting changing repeatedly with householder's applied business type of obtaining, and causes frequent distribution of interface-free resources and release.Filtering constant tau detection time is configurable, and it has determined the result of current detection cycle identification to receive the weight of historical sense cycle recognition result influence.Filtering constant tau detection time is big more, and historical testing result weight is big more, and the result who obtains is level and smooth more, but just lags behind more for current user's applied business reacting condition simultaneously.
Step 202, wireless side for detected with householder's applied business type; Through the QoS resource allocation policy of setting in advance and the mapping relations between the main applied business type; Carry out resource allocation to connecting with the householder; Because each professional sense cycle user's main applied business type possibly change, the resource allocation of wireless side will dynamically update according to the Internet resources of this variation to the user.This step comprises:
(1) configuration mapping: wireless side is through confirming as the QoS resource allocation policy that guarantees this business configuration with householder's applied business type.For different customer service models, various network resource distribution, QoS resource allocation policy and mapping relations are what can join flexibly.
(2) resource allocation: the wireless side QoS resource allocation policy according to configuration carries out resource allocation, comprises bandwidth, dispatching priority etc.
Step 203, for the applied business of implementing the QoS resource allocation policy; With obtaining stable bandwidth and higher dispatching priority; Simultaneously mean that also wireless side consumes more Internet resources for it; For reasonable disposition and the use that guarantees whole Internet resources; Simultaneously also for the resource malice that prevents to exist takies behavior, the present invention guarantees to provide the protection restore funcitons for carrying out the QoS application service, and promptly wireless side obtains the statistical monitoring that applied business (being current main applied business type) that QoS guarantees continues to carry out flow and Mean Speed for the user; Surpass the QoS shutter in limited time at flow or Mean Speed, the Internet resources that distribute are discharged.
(1) protection detects: wireless side is carrying out the QoS applied business and is obtaining Internet resources carrying out integrated flow and Mean Speed after QoS guarantees in each protection sense cycle monitor user '.
(2) resource discharges: when integrated flow or Mean Speed surpass preset thresholding, the Internet resources that distribute are discharged, the do not reentry QoS of wireless side of its applied business is guaranteed.

Step 302, wireless side analytic message obtain the applied business type of message, count on simultaneously in the traffic statistics item of corresponding applied business.
Step 303, the applied business type QoS applied business type whether of judging message, if, then change 304 over to, otherwise direct end process flow process.
Step 304, judge whether current message is the message of first QoS applied business type, if, and change step 305 over to then with the current main applied business type of the corresponding applied business type of this message as the user; Otherwise change periodically detecting pattern processing over to.
The corresponding QoS resource allocation policy of main applied business type that step 305, wireless side finding step 304 are confirmed;
The strategy that step 306, basis are found carries out the wireless side resource allocation.
Below only be concrete the handle instance of wireless side when receiving first QoS applied business type message; In the inventive method; Also can handle when wireless side is received first QoS applied business type message, for example when wireless side is received first QoS applied business type message, can be left intact by other mode; This is also little to the influence of its QoS for the stable user who continues to carry out applied business.
Handling process sketch map when Fig. 4 carries out periodically detecting for wireless side among the present invention; As shown in Figure 4; In user's applied business time-continuing process, wireless side is carried out main applied business type detection and carries out the detailed process of wireless side resource allocation following in each professional sense cycle:
Step 401, cycle detection timer expiry, the wireless side startup periodically detects with householder's applied business type.
Step 402, according to the historical flow accounting of application type of service in the flow proportional of current detection each applied business type in the cycle and the one-period of lasting; Calculate the filtered flow accounting of current each applied business type, thereby calculate user's in this sense cycle main applied business type.
Certainly, also can not carry out Filtering Processing in this step, that is to say the historical flow accounting of not considering each type of service, and directly confirm the main applied business type in this cycle according to the flow accounting of current detection each applied business type in the cycle.Particularly, be with current detection in the cycle the maximum applied business type of flow accounting as main applied business type.
Step 403, judge current whether changing,, show then that the user is current to have obtained the professional needed wireless side resource allocation of current application if do not change with householder's applied business type, the detection of end flow process, otherwise change step 404 over to.
Step 404, wireless side are searched the new corresponding QoS resource allocation policy of main application type;
Step 405, carry out the renewal of wireless side resource allocation according to new strategy.
