The situation that Path does not partly exist Quey Param part is only there is owing to there is URL as mentioned above, therefore, may exist URL#D and URL#E only comprise Path part the degree of depth and Path value situation (namely, situation 1), also whole title of Quey Param and the situation (that is, situation 2) of parameter value in the degree of depth and Path value and Quey Param part comprising Path part may be there is in URL#D and URL#E.

Below, respectively the process of above-mentioned two situations is described.

Situation 1

Gateway device can travel through the Path value of the degree of depth at different levels in the Path part of URL#D and URL#E, when the degree of depth of the Path part of URL#D with URL#E is identical, in other words, when the progression that Path part comprises is identical, compare step by step, such as, first the first order Path value in the Path part of URL#D and URL#E can be compared, namely, character string between first "/" symbol and second "/" symbol, then the second level Path value in the Path part of URL#D and URL#E is compared, namely, character string between second "/" symbol and the 3rd "/" symbol, the like.

Thus, can path value is identical in URL#D and URL#E rank, and, this identical Path value.

Such as, if the Path part of URL#D is :/sec (44ab57eec5d981faa33)/frag (0)/video/484/516/56615484_mp4_h264_aac_1.flv;

Further, the Path part of URL#E is :/sec (98ac09efd2e662cef97)/frag (0)/video/580/720/56615484_mp4_h264_aac_1.flv,

Then gateway device can determine rank the 2nd grade that in URL#D and URL#E, path value is identical, 3rd level and the 5th grade.

Thus, the video website that gateway device can determine to issue this video D is the fragment being identified video by the 2nd in Path part in URL grade, 3rd level and the 5th grade, such as, the 2nd grade can be determined in Path part, the value of 3rd level and the 5th grade is used to indicate this video D.

And then, identification division extraction model can be defined as in the Path part for extracting URL in Path part the 2nd grade, the Path value of 3rd level and the 5th grade.

Alternatively, the method also comprises:

Obtain the 4th sampling URL and the 4th video, wherein, the 4th sampling URL is corresponding with the 4th video, the 4th sample video and the 3rd sample video different;

According to identification division extraction model, determine the identification division of the 4th sampling URL;

Determine the identification division and the 3rd of the 4th sampling URL sample URL identification division between lap, this lap comprises the identical Path rank of Path value and/or the identical Quey Param of parameter value;

This lap is removed, to upgrade the identification division of the 3rd sampling URL from the identification division of the 3rd sampling URL;

According to the identification division of the 3rd sampling URL after renewal, upgrade this identification division extraction model.

Specifically, in order to improve the accuracy of the identification division extraction model determined as mentioned above further, can also obtain and the URL#N (the 4th sample the routine of URL) corresponding to video N (the 4th sample video an example), wherein, issue this video N identical with the video website of video D, further, this video N and video D different (such as, video frequency abstract is different).

Such as, if the Path part of URL#N is :/sec (74cf57abe5f336fbe78)/frag (0)/video/665/896/91362310_wma_p135_aac_8.flv;

Then gateway device can determine rank the 2nd grade that in URL#N, URL#D and URL#E, path value is identical and 3rd level, and then can to judge in Path part that the 2nd grade and 3rd level can not be used for distinguishing video.

Such as, thus the video website that gateway device can determine to issue this video D and video N is the fragment being identified video by the 5th in Path part in URL grade, can determine that the value of in the Path part of URL#D the 5th grade is used to indicate this video D.

And then, identification division extraction model can be defined as in the Path part for extracting URL the Path value of in Path part the 5th grade.

Situation 2

Gateway device can travel through the parameter value of each Quey Param in the Quey Param part of URL#D and URL#E, thus, the Quey Param that in URL#D with URL#E, parameter value is identical can be determined, and, this identical Path value.

Such as, if the Quey Param part of URL#D is:

4&ipbits＝0&signature＝.BC606865625583C2BE5AA6472A7536D827ED7E58&sver＝3&expire＝1252105200&key＝yt1&factor＝1.25&burst＝40&id＝c19764dece17ab

Further, the Quey Param part of URL#E is:

5&ipbits＝1&signature＝9879DD9541B65704625CAB118092DFD151856C&sver＝4&expire＝1252105201&key＝yt1&factor＝2.25&burst＝50&id＝c19764dece17ab

Then gateway device can determine that the parameter value of the Quey Param of parameter " key " " with id " by name in URL#D with URL#E is identical.

Such as, thus gateway device can determine that the video website issuing this video D identifies video by " key " " and id " parameter in Quey Param part in URL, can determine that the parameter value of " key " " and id " is used to indicate this video D.

And then identification division extraction model can be defined as " key " " and id " parameter for extracting in the Quey Param part of URL by gateway device.

Specifically, if first gateway device receives URL#F, then can determine the video F corresponding with URL#F (here, URL#F can corresponding complete video F, also can the fragment of corresponding video F), wherein, this video F can be that gateway device obtains from server, also can be gateway device utilize the identification division in URL#F and obtain from the video of buffer memory (subsequently, to determine the second video corresponding to target URL, this process is described in detail).Thereafter, total duration (that is, the duration of the first video) of this video F can be determined.Thus a judgement scope (that is, preset range) can be determined, this judges the time of reception of initial time as URL#F of scope, and this judges the total duration of the duration of scope as this video F.

If the time of reception of URL#G is positioned at this judgement scope, and this URL#G is equally from subscriber equipment F, then can think the corresponding same video of URL#F and URL#G.The URL of time of reception beyond this judgement scope then can not as this URL#G.

According to the video frequency identifying method of the embodiment of the present invention, the acquisition time interval of the 4th sampling URL and the 5th sampling URL is in preset range, and this preset range determines according to the duration of the 3rd all corresponding sample video of the 4th sampling URL and the 5th sampling URL, the different fragments of corresponding 3rd sample video of the 4th sampling URL and the 5th sampling URL difference can be guaranteed, thus the validity of Rang extracting section model can be improved.

Should understand, the method of the corresponding same video of determination URL#F and URL#G more than enumerated is only exemplary illustration, the present invention is not limited thereto, such as, the identification division of URL#F and URL#G can be extracted according to above-mentioned identification division extraction model, and after determining that the identification division of URL#F with URL#G is identical, determine the corresponding same video of URL#F and URL#G.

Gateway device is after this URL#G of acquisition, Path part and/or the Quey Param part of this URL#G can be extracted, and the degree of depth and the Path value of the Path part of URL#G can be determined, and the title of whole Quey Param and parameter value in the Quey Param part of URL#G, and record above-mentioned information to generate the second information aggregate.This process is similar to the above-mentioned processing procedure for URL#F, and here, in order to avoid repeating, description is omitted.

Alternatively, the 4th sampling URL is the URL that first user equipment sends when acquisition request the 3rd sample video, and the 5th sampling URL is the URL that this first user equipment sends when the fragment of acquisition request the 3rd sample video; Or

4th sampling URL is the URL that first user equipment sends when the fragment of acquisition request the 3rd sample video, and the 5th sampling URL is the URL that this first user equipment sends when acquisition request the 3rd sample video; Or

4th sampling URL is the URL that first user equipment sends when the first fragment of acquisition request the 3rd sample video, 5th sampling URL is the URL that this first user equipment sends when the second fragment of acquisition request the 3rd sample video, wherein, this first fragment and this second fragment different.

Specifically, in embodiments of the present invention, time before the period, T1 was in period T2, this URL#F can be user's (when such as, user clicks and plays icon) video website when asking the complete video of viewing is the URL that this subscriber equipment issues.And above-mentioned URL#G can be user when there is drag action video website is the URL that this subscriber equipment issues.Or time after the period, T1 was in period T2, this URL#G can be user's (when such as, user clicks and plays icon) video website when asking the complete video of viewing is the URL that this subscriber equipment issues.And above-mentioned URL#F can be user when there is drag action video website is the URL that this subscriber equipment issues.Again or, during this URL#F can be user there is drag action ask fragment of watching video, video website is the URL that this subscriber equipment issues.And video website is the URL that this subscriber equipment issues during above-mentioned URL#G can be user there is drag action ask another fragment of watching video, thus, can guarantee that this URL#G is relevant to the fragment of the character string that there are differences in this URL#F and video, and then the accuracy of Rang extracting section model of the invention process can be improved.

Alternatively, the sample Host character string partly of URL of the 4th sampling URL and the 5th is identical.

Specifically, the rule used when generating URL due to same video website is usually identical, such as, for two video segments, title for the rank or Quey Param that represent the Path part of the position of this fragment in the video of source is usually identical, therefore by selecting URL that Host part is identical as above-mentioned URL#F and URL#G, can guarantee that the video website generating this URL#F with URL#G is identical, thus the accuracy of this Rang extracting section model can be improved.

After obtaining first information set and the second information aggregate as mentioned above, contrast process can be carried out, to determine Rang extracting section model to above-mentioned first information set and the second information aggregate.

The situation that Path does not partly exist Quey Param part is only there is owing to there is URL as mentioned above, therefore, the situation of the degree of depth and the Path value only comprising Path part may be there is in first information set and the second information aggregate (namely, situation 3), also whole title of Quey Param and the situation (that is, situation 4) of parameter value in the degree of depth and Path value and Quey Param part comprising Path part may be there is in first information set and the second information aggregate.

Below, respectively the process of above-mentioned two situations is described.

Situation 3

Gateway device can travel through the Path value of the degree of depth at different levels in the Path part of URL#F and URL#G, when the degree of depth of the Path part of URL#F with URL#G is identical, in other words, when the progression that Path part comprises is identical, compare step by step, such as, first the first order Path value in the Path part of URL#F and URL#G can be compared, namely, character string between first "/" symbol and second "/" symbol, then the second level Path value in the Path part of URL#F and URL#G is compared, namely, character string between second "/" symbol and the 3rd "/" symbol, the like.

Thus, can path value is different each other in URL#F and URL#G rank, and, this different Path value, that is, corresponding above-mentioned first condition.

Such as, if the Path part of URL#F is :/sec (44ab57eec5d981faa33)/frag (0)/video/484/516/56615484_mp4_h264_aac_1.flv;

Further, the Path part of URL#G is :/sec (44ab57eec5d981faa33)/frag (1)/video/484/516/56615484_mp4_h264_aac_1.flv,

Then gateway device can determine the rank the 2nd grade that in URL#F and URL#G, path value is different each other, and in URL#F and URL#G each other different path value be frag (0) and frag (1).

Thus, gateway device can determine that by the second level in Path part in URL (namely the video website issuing this video F is, frag) fragment of video is identified, such as, can determine that the value of " frag " is used to indicate this video segment relative to the initial time of complete video or end time.

And then, Rang extracting section model can be defined as the path value of in the Path part for extracting URL the 2nd grade.

Situation 4

Such as, in embodiments of the present invention, the situation that first information set is identical with the quantity of Quey Param in the second information aggregate may be there is, namely, video corresponding to URL#F and URL#G is the different video fragment of same video, therefore, the quantity of the Quey Param in the Quey Param part of URL#F and URL#G, or the quantity of the parameter name of Quey Param is usually identical.

In the case, but Quey Param that parameter value different identical by reduced parameter name, can determine the parameter name of the fragment for identifying video, that is, corresponding above-mentioned second condition.

Such as, if the Quey Param part of URL#F is:

10200&key＝25b11c805e36d6aef3038550860c680040cdaa4201&playtype＝1&tk＝155012700719935787180022220&brt＝3&bc＝0&nt＝0&du＝538470&sz＝179904090&tflvbegin＝18055261；

Further, the Quey Param part of URL#G is:

10200&key＝25b11c805e36d6aef3038550860c680040cdaa4201&playtype＝1&tk＝155012700719935787180022220&brt＝3&bc＝0&nt＝0&du＝538470&sz＝213602090&tflvbegin＝28941773，

Then gateway device can determine that the parameter value of the Quey Param of parameter " sz " and " tflvbegin " by name in URL#F and URL#G is different each other.

Thus, gateway device can determine that the video website issuing this video F identifies the fragment of video by " sz " and " tflvbegin " parameter in Quey Param part in URL, such as, can determine that the parameter value of " sz " and " tflvbegin " is used to indicate this video segment relative to the length of complete video and initial time.

And then part charge extraction model can be defined as extracting " sz " parameter in the Quey Param part of URL and " tflvbegin " parameter by gateway device.

Again such as, in embodiments of the present invention, the situation that the quantity of Quey Param in first information set and the second information aggregate is different may also be there is.Such as, a fragment of the corresponding complete video F of URL#F and the corresponding video F of URL#G, this URL#F can be user's (when such as, user clicks and plays icon) video website when asking the complete video of viewing is the URL that this subscriber equipment issues.And above-mentioned URL#G can be user when there is drag action video website is the URL that this subscriber equipment issues, therefore, the quantity of the Quey Param in the Quey Param part of URL#F and URL#G, or the quantity of the parameter name of Quey Param may be different, that is, corresponding above-mentioned Article 3 part.

Such as, if the Quey Param part of URL#F is:

10200&key＝25b11c805e36d6aef3038550860c680040cdaa4201&playtype＝1&tk＝155012700719935787180022220&brt＝3&bc＝0&nt＝0&du＝538470；

Further, the Quey Param part of URL#G is:

10200&key＝25b11c805e36d6aef3038550860c680040cdaa4201&playtype＝1&tk＝155012700719935787180022220&brt＝3&bc＝0&nt＝0&du＝538470&sz＝179904090&tflvbegin＝18055261，

Then gateway device can determine that the Quey Param's of parameter " sz " and " tflvbegin " by name in URL#G is not present in URL#F.

And then Rang extracting section model can be defined as extracting " sz " parameter in the Quey Param part of URL and " tflvbegin " parameter by gateway device.

It should be noted that, in the embodiment above, list use two URL and train the process obtaining Rang extracting section model, but the present invention is not limited thereto, a more URL can be adopted to train and to obtain Rang extracting section model, such as, as described above by contrast URL#F and URL#G thus determine that dissimilar parts (comprises different Path rank and Path value, and/or, the title of different Quey Param and parameter value, be denoted as the ease of distinguishing, dissimilar parts A) after, URL#Y can also be obtained, this URL#Y and subscriber equipment F (namely, one example of first user equipment) corresponding, and, this URL#Y is corresponding with video F, wherein, the acquisition process of this URL#Y can be similar with the acquisition process of URL#F and URL#G, here in order to avoid repeating, description is omitted.Thereafter, URL#Y and URL#F or contrast URL#Y and URL#G can be contrasted, find out dissimilar parts and (comprise different Path rank and Path value, and/or, the title of different Quey Param and parameter value, be denoted as the ease of distinguishing, dissimilar parts B), and this dissimilar parts A and dissimilar parts B is contrasted, therefrom remove identical part and (comprise identical Path rank and Path value, with title and the parameter value of identical Quey Param) as the training foundation of Rang extracting section model, the accuracy of Rang extracting section model of the present invention can be improved further.

In addition, as mentioned above, in Rang part each character string can comprise multiple parameter, such as, " sz " and " tflvbegin ", and multiple parameter can indicate this video segment relative to the length of complete video and initial time respectively, therefore, need the concrete effect determining each parameter, such as, be carry out indicating length (or, initial time) by " sz ", or carry out indicating length (or, initial time) by " tflvbegin ".

Exemplarily non-limiting, the concrete effect of each parameter can be determined by checking, specifically, such as.Gateway device can obtain the URL#W corresponding with the video segment of video W, and, above-mentioned Rang extracting section model can be utilized to obtain the Rang part of this URL#W, such as, this URL#W gateway device can be supposed to carry out indicating length by " sz " in this URL#W, and indicate initial time by " tflvbegin ", thus, a video segment W1 can be obtained from the video W of buffer memory.And, server can be sent to by comprising this URL#W, thus, video segment W2 accurately can be obtained from server, if video segment W1 is identical with video segment W2, then can determine that hypothesis is set up, namely carry out indicating length by " sz ", and indicate initial time by " tflvbegin ", if not identical, then can determine to indicate initial time by " sz ", and indicate degree by " tflvbegin ".

Again such as, gateway device can obtain with multiple video segments of video M (here, for the ease of understanding, for two, i.e. video segment M1 and video segment M2) corresponding URL#M1 and URL#M2, and, above-mentioned Rang extracting section model can be utilized to obtain the Rang part of this URL#M1 and URL#M2, such as, this URL#W gateway device can be supposed to carry out indicating length by " sz " in this URL#M1 and URL#M2, and indicate initial time by " tflvbegin ", thus, can according to the Rang part of this URL#M1 and URL#M2, the length extrapolating this video M (is called, calculate length), and, from the video frequency abstract of URL#M1 or URL#M2, gateway device can know that the length of this video M (is called, physical length), if calculate that length is identical with physical length, then can determine that hypothesis is set up.

After as above this acquisition Rang extracting section model, the Rang part in URL#A and URL#B can be determined according to this Rang extracting section model, and removed, thus, the interference of identification division can be got rid of, and then, the accuracy of this Session extracting section model can be improved.

After the interference getting rid of identification division and Rang part as mentioned above, the Session part in URL#A and URL#B can be determined.

The situation that Path does not partly exist Quey Param part is only there is owing to there is URL as mentioned above, therefore, may deposit Session part only comprise Path part the degree of depth and Path value situation (namely, situation 5), also may there is this Session part and comprise whole title of Quey Param and the situation (that is, situation 6) of parameter value in the degree of depth of Path part and Path value and Quey Param part.

Below, respectively the process of above-mentioned two situations is described.

Situation 5

Gateway device can travel through the Path value of the degree of depth at different levels in the Path part of URL#A and URL#B, when the degree of depth of the Path part of URL#A with URL#B is identical, in other words, when the progression that Path part comprises is identical, compare step by step, such as, first the first order Path value in the Path part of URL#A and URL#B can be compared, namely, character string between first "/" symbol and second "/" symbol, then the second level Path value in the Path part of URL#A and URL#B is compared, namely, character string between second "/" symbol and the 3rd "/" symbol, the like.

Thus, can path value is identical in URL#A and URL#B rank, and, this identical Path value.

Such as, if the Path part of URL#A is :/sec (44ab57eec5d981faa33)/frag (0)/video/484/516/tape (NOR) 56615484_mp4_h264_aac_1.flv;

Further, the Path part of URL#B is :/sec (44ab57eec5d981faa33)/frag (0)/video/484/516/tape (HD)/56615484_mp4_h264_aac_1.flv,

Gateway device, according to above-mentioned identification division extraction model, can determine that " 56615484_mp4_h264_aac_1.flv " in the Path part of this URL#A and URL#B is identification division.
