Present invention could apply to Long Term Evolution（LTE, Long Term Evolution) in network, it can be used for the UMTS with LTE features（UMTS, Universal Mobile Telecommunications System) in, the embodiment of the present invention, which is illustrated but is not limited exemplified by applied to LTE, determines.

The flow chart of application stream detection method one embodiment that Fig. 1 provides for the present invention, as shown in figure 1, this method includes：

5101st, controlled entity receives application stream.

It should be noted that controlled entity can be PCEF, corresponding processing rule can be PCC rule shellfishes IJ;Or, controlled entity can be current detection functionality（TDF, Traffic Detection Function) entity, corresponding processing rule can be to apply Detection ＆ Controling（ADC, Application Detection and

Control ) .Wherein, handling rule is used to be matched with the feature of the application stream of reception.

5102nd, controlled entity will simultaneously be matched using stream with least one corresponding processing rule, it is determined that priority highest first handles rule in the processing rule that the match is successful in time span.

It should be noted that multiple PCC rules for performing application stream detections can concomitantly be used for and using the matching of stream in controlled entity, such as PCEF, and SP, multiple PCC rules, which can be started simultaneously at, to be matched. It is described using the detection process of stream in the agreements of 3GPP TS 23.203, corresponding priority argument is also defined in the protocol, herein not reinflated explanation.

Exemplary, PCEF will can be matched simultaneously using stream with corresponding PCC rules, as shown in Fig. 2 abscissa is time shaft, ordinate is PCC rules.Using stream matching is started simultaneously at corresponding PCC rules 1, PCC rules 2, PCC rules 3, PCC 4 and PCC of rule rules 5.Wherein, PCC 1 priority of rule is a, PCC 2 priority of rule are that regular 3 priority of d, PCC are that regular 4 priority of c, PCC are b and regular 5 priority of PCC are b, and the priority highest that the order of priority for the application stream is d, down arrangement is followed successively by ^ b, a.

Further, because the application characteristic information that each PCC rules are included is different, the speed completed using stream matching is also different, as shown in the time shaft of Fig. 2 abscissas, the order that PCC rules complete matching is followed successively by PCC rules 5, PCC rules 1, PCC rule shellfishes lj 3, the standing grain Jie PCC rule shellfishes lj 4 of PCC rule shellfishes lj 2.If the time span is enough to ensure that the match is successful with application stream by PCC rules 2, it is the first processing rule that priority highest PCC rules 2, which can then be determined, if the time span is not sufficient to ensure that the match is successful with application stream by PCC rules 2, the order according to above-mentioned d, c, b, a in the PCC rules that the match is successful can then be determined, selecting priority highest PCC rules are regular as the first processing, for example：It has selected PCC rules 3 (corresponding priority is c).Herein only with this for example, might not PCC rule corresponding match times and priority be limited in any way.

It should be noted that the match is successful for application stream detection process, for example, it can include：

The five-tuple information of IP packets will be parsed and application layer (layer 7) information of analysis Match IP packet completes to match with PCC rules, and the application layer message for analyzing Match IP packet is completed to match two ways with PCC rules.

This sentence controlled entity be PCEF, processing rule be PCC rule exemplified by illustrate, by controlled entity be TDF, processing rule be ADC rule exemplified by when it is as the same.

S103, controlled entity send the first regular corresponding application stream information of processing to PCRF entities.Application stream detection method provided in an embodiment of the present invention, controlled entity receives application stream, to simultaneously it be matched with least one corresponding processing rule using stream, it is determined that priority highest first handles rule in the processing rule that the match is successful in time span, and the first regular corresponding application stream information of processing is sent to PCRF entities.So, it can be ensured that report the corresponding application stream information of processing rule of high priority, to reduce Signalling exchange load, and be prevented effectively from the deviation that execution is controlled using Flow Policy. The flow chart for application stream detection method another embodiment that Fig. 3 provides for the present invention; the present embodiment using perform entity as PCEF, processing rule be that PCC rules are illustrated; but any restriction is not done with this; it is that TDF entities, processing rule are that ADC rules are same within protection domain to perform entity; as shown in Fig. 3, this method includes：

S201, PCEF receive the time span that PCRF entities are sent.

Another optional embodiment is that PCEF obtains time span from local, obtained time span is consistent with the time span received from PCRF entities, can refer to the time span received that the present embodiment provides and determines that scheme determines the time span locally obtained.

Exemplary, time span can be the regular maximums that the successful time is flowed from startup matching process to matching application of all PCC for performing application stream detection in PCRF.SP, the time span is reflected

All PCC rules for performing application stream detection detect that logic is different, this time can generally achieve second level, such as 5 seconds from matching process is started to matching using successful relative time maximum is flowed according to the deep packet of application stream detection in PCRF.The time span so determined can ensure that all PCC rules all complete the matching of application stream in the time span as far as possible.

Or, time span is regular from matching process is started to maximum of the matching using the stream successful time for the PCC in PCRF applied to PCEF all execution application stream detections.SP, the time span reflects the PCC rules for all execution application stream detections that the PCEF is applied in PCRF from matching process is started to the successful relative time maximum of matching application stream.From unlike above-mentioned time span, this time span be for PCRF control some PCEF in all execution application stream detections PCC rule determine.

Or, time span be have in PCRF highest priority parameter be used for perform the PCC rules of application stream detection and flow successful time from starting matching process to matching application.SP, the time span reflect have in PCRF highest have it is first weighing, flow successful relative time for performing the PCC rules of application stream detection from starting matching process to matching application.Relatively successful match priority highest PCC rules complete the time detected to the time span so determined.

Or, time span flows the successful time from startup matching process to be applied to the PCEF PCC rules for being used to perform application stream detection with highest priority parameter in PCRF to matching application.S Jie, the time span reflect in PCRF applied to the PCEF, have with highest first weight parameter, for performing the PCC rules of application stream detection from starting matching process to matching application flow successful relative time.The time span so determined completes detection closest to successful match priority highest PCC rules Time.

Alternatively, the time span can be handed down to PCEF by PCRF during IP-CAN session establishments, and the time span of renewal can be handed down into PCEF during IP-CAN session modifications.PCEF is received after the time span of the renewal, refreshes original time span automatically.

S202, PCEF receive application stream.

Alternatively, the application as PCEF for each flowing through PCEF is flowed, when carrying out application stream detection, a timer inside PCEF startups, and the duration of timer is equal to above-mentioned time span.

5203rd, PCEF will simultaneously be matched using stream with least one corresponding processing rule.

PCEF then performs step S204 if it is determined that the match is successful in time span;Do not determine that the match is successful in time span, then perform step S206.

5204th, PCEF determines that priority highest first handles rule in the processing rule that the match is successful in time span.

Exemplary, as shown in figure 4, starting simultaneously at matching with corresponding PCC rules 1, PCC rules 2, PCC rules 3, PCC 4 and PCC of rule rules 5 using stream.Wherein, PCC 1 priority of rule is a, PCC 2 priority of rule are that regular 3 priority of d, PCC are that regular 4 priority of c, PCC are b and regular 5 priority of PCC are b, and the priority highest that the order of priority for the application stream is d, down arrangement is followed successively by ^ b, a.And, the order that PCC rules complete matching is followed successively by PCC rules 5, PCC rule shellfishes IJ 1, PCC rule shellfishes IJ 3, the standing grain Jie PCC rule shellfishes lj 4 of PCC rule shellfishes IJ 2.

Alternatively, if it is determined that time span be I seconds, ended to I seconds, successful match has arrived the PCC rules 1 that priority is a and the PCC rules 5 that priority is b, the failed PCC rules matched with highest priority d, 1 and PCC of the PCC rules rules 5 that the match is successful before cut-off in I seconds are then contrasted into priority, priority highest PCC rules are selected as the first processing rule, i.e. PCC rules 5 as the first processing rule.

Alternatively, if it is determined that time span be J seconds, in J seconds, previous matching application is flowed into successful PCC rules to be compared with the successful PCC rules of the same application stream of current matching, according to comparative result, retain the higher PCC rules of priority as current matching application and flow successful PCC rules, by that analogy, until the PCC rules of priority resolution highest the first during time span cut-off.Such as, the priority of PCC rules 1 and PCC rules 5 is compared, retain the priority of PCC rules 5, the priority of PCC rules 5 and PCC rules 3 is compared again, retain PCC rules 3 until J second, obtained priority highest PCC rules 2 will be compared and be used as successful first PCC of current matching application stream Rule.

Alternatively, however, it is determined that time span be I second, from time span matching application stream during successfully whole PCC is regular the PCC of priority resolution highest the first it is regular.It is that priority highest first handles rule to determine PCC rules 5, herein because time span is I seconds, only illustrated exemplified by comparing PCC 5 and PCC of rule rules 1, but do not limited with this, when the match is successful in time span multiple PCC are regular, the regular selecting priority highests one of relatively all PCC.

Alternatively, however, it is determined that time span be H second, the match is successful for PCC with highest priority rule 2, it is determined that PCC rules 2 are the first PCC regular；If it is determined that time span be J second, the PCC regular 2 of highest priority has been had been detected by H second, and the match is successful, then no longer PCC regular 4 can be detected, but regard PCC rules 2 as the first PCC rule process.

5205th, PCEF sends the first regular corresponding application stream information of processing to PCRF entities.

So, PCEF would not report unnecessary application stream information to PCRF, the corresponding application stream information of PCC rules of low priority is reported into PCEF, but the corresponding application stream information of the high priority of determination is reported into PCRF, reduce the Signalling exchange load between PCEF and PCRF.Simultaneously, it it also avoid the processing logic that PCRF starts incorrect application Flow Policy control or charging control, such as according to the corresponding application stream information of the PCC of low priority rules further to the control of PCEF Provisioning Policies or charging control rule, so as to effectively avoid the deviation that PCRF is performed to the policy control of application stream information.

5206th, PCEF abandons application stream.

PCEF does not determine that the processing rule that the match is successful can consider that this occurs in that mistake using stream, is abandoned.

Application stream detection method provided in an embodiment of the present invention.Controlled entity receives application stream, to simultaneously it be matched with least one corresponding processing rule using stream, it is determined that priority highest first handles rule in the processing rule that the match is successful in time span, and the first regular corresponding application stream information of processing is sent to PCRF entities.So, it can be ensured that report the corresponding application stream information of processing rule of high priority, to reduce Signalling exchange load, and be prevented effectively from the deviation that execution is controlled using Flow Policy.The structural representation for the controlled entity embodiment that Fig. 5 provides for the present invention, as shown in figure 5, the controlled entity 50, including：

Further, as shown in fig. 6, the controlled entity 50, in addition to：

Timing unit 504, for obtaining time span from local；Or, receive the time span that PCRF entities are sent.

Exemplary, the acquisition of timing unit 504 or reception time span, the i.e. time span applied to processing unit 502 are all regular maximums that the successful time is flowed from startup matching process to matching application of the processing for performing application stream detections in PCRF.

Or, time span that is that timing unit 504 is obtained or receiving, the i.e. time span applied to processing unit 502 are the processing rule for all execution application stream detections that controlled entity is applied in PCRF from the maximum for starting matching process and being flowed to matching application successful time.

Alternatively, if processing unit 502 to time span is ended, the processing rule with highest priority is matched not successfully, then priority highest handles rule as the first processing rule in the processing rule that the match is successful before time span is ended.

Alternatively, the successful processing rule of previous matching application stream is successfully handled rule with the same application stream of current matching and is compared by processing unit 502 in time span；According to comparative result, retain the higher processing rule of priority as the successful processing rule of current matching application stream；By that analogy, until priority resolution highest first handles rule when time span is ended.

Alternatively, the priority resolution highest first from the successful all processing rule of matching application stream in time span of processing unit 502 handles rule.

Further, as shown in fig. 7, the controlled entity 50, in addition to： Discarding unit 505, if in the range of time span, not determining that shellfish lj is advised in the processing that the match is successful, then abandoning application stream.
