Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Each OTT is applied in end side can send signaling to network side, and network side generates application layer data in application layer according to this signaling.Miscellaneous OTT application can be installed on practical application intelligent terminal, and each OTT application can produce different behaviors on intelligent terminal, for example, the OTT application such as Tencent QQ, microblogging, Wei Xin ,You Ku, Sohu video.When user uses different OTT to apply by intelligent terminal in the different moment, while chatting, sending out the behaviors such as picture and intercommunication in real time as micro-letter, microblogging and Tencent QQ etc., because these OTT application all send signaling by same intelligent terminal to network side, therefore, the application layer of network side cannot be judged the identity of the OTT application that sends chat or send out picture signaling, that is to say, it is micro-letter that the application layer of network side cannot be determined the OTT application that sends this chat or send out picture signaling, or microblogging or Tencent QQ.In order to address the above problem, the present embodiment provides a kind of data grab method of OTT application.
The schematic diagram of the data grab method that a kind of OTT that Fig. 1 provides for the embodiment of the present invention applies.For can the Signaling Layer data of OTT application are corresponding with the application layer data of this OTT application, need to be for the terminal equipment of operating system be only installed for realizing the target terminal of the data crawl of OTT application in the present embodiment.This target terminal can be mobile phone or personal digital assistant's (Personal Digital Assistant is called for short PAD) etc.
The executive agent of the data grab method of the OTT application that the present embodiment provides can be the data grabbing device of OTT application.As shown in Figure 1, the method comprises the following steps:
101, to target terminal, send for capturing first of Signaling Layer data and capture instruction, so that described destination end generates the first packet that carries sync id, described first captures instruction indicates described target terminal from T
1constantly to T
2constantly close OTT application to be measured, from T

4constantly close described OTT application, from T
4constantly reopen described OTT application, wherein, described sync id is the data slice with pulse signal characteristic, for realizing end side, synchronizes with the data between network side.
102, to equipment of the core network, send for capturing second of application layer data and capture instruction, so that described equipment of the core network generates the second packet.
In the present embodiment, due to target terminal on installing operating system, when the needs Signaling Layer data that synchronously the some OTT of crawl apply and application layer data, this OTT application to be measured is installed on this target terminal.From third-party server, pass through transmission control protocol/Internet Interconnection agreement (Transmission Control Protocol/Internet Protocol, be called for short TCP/IP), get the installation kit of this OTT application to be measured, then this OTT application to be measured is installed on target terminal, after this OTT application is installed, on the server of this OTT application, register login account, to realize, the data of OTT application are captured.
On target terminal, be integrated with Signaling Layer data capture module, by this Signaling Layer data capture module, capture the signaling data that OTT application to be measured is sent.On the equipment of the core network of network side, be integrated with application layer data handling module, by this application layer data handling module, capture the application layer data of OTT application to be measured.Wherein, this Signaling Layer data capture module and application layer data handling module all can be for realizing by hardware or software.In the present embodiment, equipment of the core network can be gateway device, GPRS serving GPRS support node (Serving GPRS SUPPORT NODE, abbreviation SGSN), mobile management entity entity (Mobility Management Entity, be called for short MME) or mobile switching centre's (Mobile Switching Center is called for short MSC).
Data grabbing device sends for capturing first of Signaling Layer data and captures instruction to target terminal, so that destination end generates the first packet that carries sync id.Synchronously, data grabbing device sends for capturing second of application layer data and captures instruction to equipment of the core network, so that described equipment of the core network generates the second packet.
Particularly, first capture instruction indicating target terminal from T

The schematic diagram of the first packet that Fig. 2 provides for the present embodiment.As shown in Figure 2, from T
1constantly to T
2constantly close OTT application to be measured, now user cannot use OTT to be measured, and OTT to be measured so just can not produce Signaling Layer data, and correspondingly, network side is at T
1constantly to T
2constantly also there will not be application layer data.From T
2constantly to T
3while constantly opening OTT application unlatching to be measured, user just can use OTT application to be measured, in the use procedure of OTT application to be measured, will produce Signaling Layer data, and correspondingly, network side is also at T
2constantly to T
3constantly produce application layer data.Now, the Signaling Layer data capture module on target terminal gets the Signaling Layer data of OTT to be measured, and correspondingly, the application layer data handling module of equipment of the core network just can get the application layer data of OTT to be measured.From T
3constantly to T
4constantly close OTT application to be measured, now user cannot use OTT to be measured, and OTT to be measured so just can not produce Signaling Layer data, and correspondingly, network side is at T
3constantly to T
4constantly also there will not be application layer data.From T
4constantly reopen OTT application to be measured, user just can be from T
4the OTT application to be measured of normal use constantly, signaling data handling module just can grab Signaling Layer data in real time.Correspondingly, application data handling module just can grab at network side the application layer data of OTT application to be measured in real time.
By above-mentioned processing procedure, target terminal is from T
1constantly, to the time period of data grabbing device transmission crawl END instruction, in the first packet of generation, can carry a sync id.Correspondingly, equipment of the core network is from T
1constantly, to the time period of data grabbing device transmission crawl END instruction, in the second packet of generation, also can carry a sync id.Wherein, from T
1constantly to T
4constantly, signaling data handling module can generate the data slice of similar and a pulse signal.The data slice that this is had to pulse signal characteristic in the present embodiment is as sync id.In the present embodiment, sync id can be stabbed as a special time, by this special time, stab to realize end side and synchronize with network side data.
