Therefore, the mobile communication network operator may determine the video playing time delay of the user watching the video, and improve the experience of the user watching the video by reducing the video playing time delay as much as possible.
A common method for determining video playing delay of a user watching a video is as follows:

Optionally, according to the content provided in fig. 2, determining a selective play timestamp and a play start timestamp corresponding to the selective play identifier:
Specifically, a video playing fingerprint table is pre-stored, and each entry in the table includes a user identifier, a play selection timestamp, and a play start timestamp, where the user identifier may be a mobile phone number of a user or other identifiers for uniquely identifying a user identity. One entry in the video play fingerprint table can be uniquely determined according to the user identifier and the selected play identifier.

Optionally, according to the content provided in fig. 3, the video playing fingerprint table is stored in advance:
In specific implementation, a user accesses a network through a mobile communication network, a user service record is generated, the user service record can be mirrored to a convergence and distribution processing server through the light splitting device, the user service record is obtained from the convergence and distribution processing server, and the user service record is obtained from the convergence and distribution processing server.
Specifically, the user service related to the embodiment of the present application is a video service, and therefore, the user service record with the service type being a video type is extracted from the stored user service records within the preset time period and is used as a reference service record, so as to obtain a video playing fingerprint table in the following.
And 303, dividing the reference service records carrying the same selective play identifier into a group.
Specifically, after the user selects to play the video, the equipment held by the user sends a URL for indicating that the video is selected to be played to the network side, and then if the video needs to be played before the video starts to be played, the equipment held by the user automatically sends an advertisement playing URL and an advertisement playing ending URL to the network side, and after the advertisement is played and the video sent by the network side is received and buffered to a certain flow response, the URL for indicating that the video starts to be played is automatically sent to the network side; if the advertisement does not need to be played before the video starts to be played, the equipment held by the user automatically sends the URL for indicating the video starts to be played to the network side after receiving the response that the video sent by the network side is buffered to a certain flow. After the user selects to play the video at this time, the URLs generated aiming at the selective playing operation all carry the same selective playing identification, and as the user service records comprise the URLs, the same selective playing identification can correspond to a plurality of reference service records. In this step, the reference service records carrying the same selective play identifier are divided into a group, so as to obtain a reference service record group corresponding to each selective play identifier.
Specifically, for each group of reference service records, the reference service record carrying the selective playing operation identifier in the group of reference service records is extracted as a first reference service record, and the reference service record carrying the start playing operation identifier in the group of reference service records is extracted as a second reference service record.
More specifically, a URL indicating that a video is selected to be played in the set of reference service records may be extracted as a first URL, and a URL indicating that the video starts to be played may be extracted as a second URL; and taking the reference service record to which the first URL belongs as a first reference service record, and taking the reference service record to which the second URL belongs as a second reference service record. The URL of the video to be played is selected to carry a play-selecting operation identifier, for example, the content of the field ac in the URL is launch, that is, the operation corresponding to the URL is a video to be played selectively; the URL where the video starts to be played carries the play start operation identifier, for example, the content of the field ac in the URL is play, that is, the operation corresponding to the URL is the video play start operation.
Step 305, using the timestamp in the first reference service record as the selective playing timestamp corresponding to the selective playing identifier corresponding to the group of reference service records, and using the timestamp in the second reference service record as the playing start timestamp corresponding to the selective playing identifier corresponding to the group of reference service records.
Specifically, a table entry is generated for each group of reference services, and the obtained table entry generated for each group of reference service records is stored in the video playing fingerprint table. For example, a video playing fingerprint table is described, as shown in table one, the video playing fingerprint table includes a user identifier, a play selection timestamp, and a play start timestamp.
