Background
With the rapid development of mobile network speed and intelligent terminals, the user traffic demand is higher and higher. In order to meet the flow demand of users, various large-flow packages are released by operators. During the use process, the user who subscribes the flow package can share the flow for other terminal users by opening the terminal hotspot.
In the prior art, a method of identifying a shared traffic terminal through terminal information is often adopted, specifically, internet access signaling list data of a target user number in a specific time period is collected, the terminal information is extracted from the internet access signaling list data, and judgment is performed on the terminal information to determine whether the terminal is the shared traffic terminal. The terminal information includes a terminal model or an operating system version. More specifically, the number of terminals whose terminal information is on line using the target user number within a specific time period is determined to determine whether the terminal is a shared traffic terminal. And determining the terminals which meet the condition that the number of the terminals is more than or equal to 2 as the shared flow terminals.
However, in the process of using the method for identifying a shared traffic terminal, for a scene shared by terminals of the same terminal model or the same operating system version, the terminal of the same terminal model or the same operating system version is identified as the same terminal, and the shared traffic terminal to be detected is mistakenly determined as a non-shared traffic terminal; for another example, when the user changes the device, the terminal to be tested is originally a non-shared traffic terminal, but the terminal to be tested is wrongly judged as a shared traffic terminal because different terminal signals or different operating system versions correspond to different terminals; for another example, for a scenario with one number of multiple terminals, misjudgment may occur in the identification of the shared traffic terminal, because the one number of multiple terminals does not belong to the traffic sharing scenario.
Therefore, the existing identification method for the shared traffic terminal has the technical problem of low accuracy.

Detailed Description
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
In order to better understand the technical solutions of the present invention, the technical solutions of the present invention are described in detail below with reference to the drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the embodiments of the present invention are detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the embodiments of the present invention may be combined with each other without conflict.
In the embodiment of the present invention, for an application scenario in which a shared traffic terminal provides a hot spot to a shared traffic terminal, signals received by the terminal may specifically be a General Packet Radio Service (GPRS), a third Generation Mobile Communication Technology (the 3-rd Generation Mobile Communication Technology)3G, a fourth Generation Mobile Communication Technology (the 4th Generation Mobile Communication Technology)4G, and a fifth Generation Mobile Communication Technology (the 5th Generation Mobile Communication Technology)5G are converted into wifi signals to be transmitted, and the wifi signals are provided for other terminals outside the terminal to use a traffic corresponding to the wifi signals, so that the shared traffic terminal shares the traffic to the shared traffic terminal. In order to improve the identification accuracy of the shared traffic terminal, the identification of the shared traffic terminal is carried out based on a corresponding relation table between a user number and a life time value. In the specific implementation process, the survival time value can represent the sharing behavior of the terminal, so that the identification accuracy of the shared traffic terminal can be improved.
Referring to fig. 1, an embodiment of the present invention provides a flow diagram of a method for identifying a shared traffic terminal, where the method specifically includes:
s101: in a specific time period, original signaling messages from M terminals to be tested are split at a PGW side of a packet domain data core network gateway, wherein M is a positive integer;
s102: analyzing the original signaling message to generate a corresponding relation table comprising a corresponding relation between a user number and a time-to-live value of each terminal to be tested in the M terminals to be tested, wherein the time-to-live value is used for limiting the maximum hop count forwarded in a network by an Internet Protocol (IP) data packet in the original signaling message;
s103: and identifying N terminals to be tested which meet the conditions in the M terminals to be tested as shared flow terminals according to the corresponding relation table, wherein N is a positive integer not greater than M.
In a specific implementation process, when M terminals to be tested surf the internet within a specific time period, original signaling messages from the M terminals to be tested are split by a Packet Data Network Gateway (PGW) side. Each terminal to be tested may be a terminal device such as a Personal Computer (PC), a tablet PC, a Personal Digital Assistant (PDA), a Personal Communication Service (PCs) phone, a notebook, a mobile phone, or a Computer having a mobile terminal, for example, a portable, pocket, handheld, Computer-embedded or vehicle-mounted mobile device, or other terminal devices that use data traffic to perform internet access. In the implementation process, the specific time period may be specifically 5min, may also be 1 hour, and may also be one day or more, and of course, a person skilled in the art may set the specific time period according to the actual usage habit of the user, which is not described herein again. In a specific implementation process, the PGW stores original signaling messages from M terminals to be tested locally after performing a light splitting process on the original signaling messages. For those skilled in the art, the PGW performs a light splitting process on the original signaling packet, that is, the PGW performs a copy process on the original signaling packet.
Then, the original signaling message is analyzed, and a corresponding relation table including a corresponding relation between a user number of each terminal to be tested in the M terminals to be tested and a Time to live value (Time to live) is generated, wherein the Time to live value is used for limiting a maximum hop count forwarded in a network by an Internet Protocol (IP) data packet in the original signaling message. For a specific example, when 5 terminals to be tested correspond to a-f and total 6 user numbers within a time period of 5min, the generated corresponding relationship table includes a corresponding relationship between the user number a and at least one time-to-live value within the time period, a corresponding relationship between the user number b and at least one time-to-live value within the time period, … …, and a corresponding relationship between the user number f and at least one time-to-live value within the time period.
Then, according to the correspondence table, the N terminals to be tested that meet the conditions in the M terminals to be tested are identified as shared traffic terminals, that is, the shared traffic terminals are identified from the M terminals to be tested by using the correspondence table as a determination condition. In the specific implementation process, the lifetime value is set for preventing the IP packet from being forwarded in the network for an unlimited number of times, the characteristic value is used for telling the network how many times the IP packet can be forwarded in the network, and the router subtracts 1 from the value corresponding to the lifetime value of the IP packet every time the IP packet is forwarded once. In the embodiment of the invention, the shared traffic terminal is identified according to the life time value capable of representing the terminal sharing behavior, so that the identification accuracy of the shared traffic terminal can be effectively improved.
In the embodiment of the present invention, in order to realize accurate identification of a shared traffic terminal, step S103: according to the corresponding relation table, identifying N terminals to be tested which meet the conditions in the M terminals to be tested as shared flow terminals, including: and if the survival time value of each user number in the N terminals to be tested in the corresponding relation table at least comprises TTL and (TTL-N), identifying the N terminals to be tested as shared flow terminals, wherein N is more than or equal to 1 and is less than or equal to TTL, and both TTL and (TTL-N) are used for representing the specific characteristic value of the survival time value in the specific time period.
In the specific implementation process, when the terminal serving as the hotspot supports forwarding of the IP data packet of the backend device, the specific value TTL corresponding to the time-to-live value is reduced by 1. For example, the characteristic value of the lifetime value of the IP header of the traffic of the terminal a user itself is 64, and the characteristic value of the lifetime value of the IP header after passing the shared traffic once is 63. As shown in table 1, the lifetime values of the shared traffic terminal and the shared traffic terminal in different operating systems (Android, IOS, WP, and Windows) are shown as one of the characteristic values. Specifically, the eigenvalue of the lifetime value after the shared traffic terminal shares the traffic for one time with the shared traffic terminal is reduced by 1 compared with the original eigenvalue.
TABLE 1
In a specific implementation process, for a complex networking or a complex scene in which a relay server appears in the middle of a shared network, a situation that a specific value TTL corresponding to a survival time value is subtracted by n (where n is an integer greater than 1) by a back-end device may occur in an identification process of a shared traffic terminal, which inevitably causes identification confusion. Therefore, in the specific implementation process, the shared traffic terminal is identified by identifying the characteristic value (TTL-n) corresponding to the time-to-live value (where n is greater than or equal to 1 and less than or equal to TTL). In the specific implementation process, if the time-to-live value of a certain user number in the corresponding relation table includes the characteristic value TTL and at least one of { TTL-1, TTL-2, … …, TTL-n }, the terminal to be detected corresponding to the user number is identified as the shared traffic terminal. For example, if the feature value corresponding to the time-to-live value of the user number a in the correspondence table includes TTL and TTL-1, the terminal to be tested corresponding to the user number a is a shared traffic terminal; for another example, if the feature value corresponding to the time-to-live value of the user number b in the corresponding relationship table includes TTL, TTL-2, and TTL-3, the terminal to be tested corresponding to the user number b is the shared traffic terminal. In the specific implementation process, when n is TTL, it indicates that the TTL is reduced to 0 before the IP packet reaches the destination IP, and the router discards the IP packet whose TTL is 0.
In the embodiment of the present invention, in order to improve the identification accuracy of the shared traffic terminal, please refer to fig. 2, step S102: analyzing the original signaling message to generate a corresponding relation table comprising the corresponding relation between the user number and the survival time value of each terminal to be tested in the M terminals to be tested, wherein the corresponding relation table comprises the following steps:
s201: analyzing the original signaling message to obtain the user number of each terminal to be tested in the M terminals to be tested and the corresponding survival time value in the IP header;
s202: and generating a corresponding relation table comprising the corresponding relation between the user number of each terminal to be tested and the survival time value.
In the specific implementation process, the specific implementation process from step S201 to step S202 is as follows:
firstly, the original signaling message is analyzed to obtain the user number of each terminal to be tested in M terminals to be tested and the corresponding survival time value in the IP header. For example, the original signaling message in 1h is analyzed to obtain the user number of each terminal to be tested in 100 terminals and the corresponding lifetime value in the IP header. And then, generating a corresponding relation table comprising the corresponding relation between the user number of each terminal to be tested and the survival time value. For example, a correspondence table is generated in which the 100 terminals include 120 subscriber numbers and corresponding lifetime values in the IP headers. For example, the corresponding relationship table includes the user number a and the corresponding characteristic value set { TTL, TTL-1} of the time-to-live value, the user number b and the corresponding characteristic value set { TTL, TTL-1, TTL-2, TTL-3} of the time-to-live value, and the user number c and the corresponding characteristic value set { TTL, TTL-2, TTL-3, TTL-5} of the time-to-live value. Of course, in the specific implementation process, the corresponding relationship table specifically changes in real time according to the specific situation of the user number and the corresponding time-to-live value in the specific time period, and is not described herein again.
In the embodiment of the present invention, in order to implement accurate control on the shared traffic terminal, please refer to fig. 3, in step S103: after the N terminals to be tested meeting the conditions among the M terminals to be tested are identified as the shared traffic terminals according to the correspondence table, the method further includes:
s301: determining target user numbers corresponding to the N terminals to be tested;
s302: generating a shared event information relation table, wherein the shared event information relation table at least comprises the target user number, the specific time period and a service Quality Class Identifier (QCI) value which is analyzed from the original signaling message and is used for representing the service level of the target user number in a network;
s303: reporting the sharing event information relation table to a PCRF (policy and control server) of a packet domain data core network through the PGW;
s304: receiving a control strategy generated by the PCRF based on the sharing event information relation table;
s305: and controlling the flow sharing behaviors of the N terminals to be tested according to the control strategy.
In the specific implementation process, the specific implementation process of step S301 to step S305 is as follows:
firstly, after N terminals to be tested meeting conditions in M terminals to be tested are identified as shared flow terminals, determining target user numbers corresponding to the N terminals to be tested; then, a shared event information relationship table is generated, wherein the shared event information relationship table at least includes the target user number, the specific time period, and a Quality of service class Identifier (Quality of service Identifier) QCI value for characterizing the service level of the target user number in the network, which is analyzed from the original signaling message. Generally, smaller values of QCI values correspond to higher levels, and vice versa. For example, the QCI value of the target subscriber number corresponding to the VIP subscriber is set to a higher level, "QCI ═ 1", and the QCI value of the target subscriber number corresponding to the general subscriber is set to a lower level, "QCI ═ 6"; for another example, the QCI value of the internet service of the target subscriber number is set to a higher level "QCI ═ 3", and the QCI value of the telephone service of the target subscriber number is set to a lower level "QCI ═ 5". Of course, those skilled in the art may set the specific value of the QCI value of the target user number according to the actual usage habit of the user, and the detailed description is omitted here.
Then, the sharing event information relation table is reported to a packet domain data core network Policy and control server (Policy and Charging Rules Function) PCRF by the PGW. Then, the PCRF generates a control strategy for differentiated flow control of the shared flow terminal under the shared flow terminal based on the relevant parameters in the shared information relation table; and then, the PCRF issues the control strategy to the PGW, and the PGW performs differentiated control on the traffic sharing behavior of the shared traffic terminal under the shared traffic terminal according to the control strategy.
In the embodiment of the present invention, step S305: controlling the flow sharing behavior of the N terminals to be tested according to the control strategy, comprising the following steps:
and blocking, limiting the speed or opening the shared flow terminals of the number of the target user or the number of the specific terminals at least according to the specific time period and the QCI value.
In a specific implementation process, the PGW blocks, limits speed or puts through the shared traffic terminals of the target subscriber number or the specific number of terminals at least according to the specific time period and the QCI value in the shared information relationship table. For example, the PGW blocks a shared traffic terminal corresponding to a target user number under each shared traffic terminal in 10 shared traffic terminals in the time period of 13:00 to 14:00 in the afternoon, or shared traffic terminals of a specific number of terminals, that is, the shared traffic terminals corresponding to the target user numbers or the shared traffic terminals of the specific data volume of the terminals will not be on the network. More specifically, for example, the traffic of the shared traffic terminal corresponding to the subscriber numbers b, c, and d of the shared traffic terminal a in this time period is blocked. For another example, the flow of any 5 shared flow terminals under the shared flow terminal B in this time period is limited in speed. Of course, a person skilled in the art may set a specific control method for the traffic sharing behavior of the PGW to the shared traffic terminal according to the actual usage habit of the user, and details are not described here. In the embodiment of the invention, the sharing traffic terminal is accurately identified based on the PGW side spectral detection, the PGW reports the sharing event information relation table to the PCRF, and then the PGW receives the control strategy generated by the PCRF based on the relevant parameters in the sharing event information relation table and blocks, limits the speed or puts through the sharing traffic terminals of the target user number or the specific terminal number, thereby realizing the differential control of the hotspot sharing behavior and protecting the network resources of operators.
Based on the same inventive concept, the embodiment of the present invention provides a shared traffic terminal identification apparatus, and because the principle of the apparatus for solving the problem is similar to the shared traffic terminal identification method, the implementation of the apparatus may refer to the implementation of the method, and repeated details are not described again.
Fig. 4 is a schematic diagram illustrating the entire process of identifying and controlling the shared traffic terminal according to the embodiment of the present invention. Specifically, a shared traffic end user sends an internet access request to a PGW; the PGW sends a CreditControl Request-Initial (CCR-I) message to the PCRF; the PCRF sends a CreditControl Answer-Initial (CCA-I) message to the PGW; the shared flow terminal user is successfully activated after confirming normal response through the PCRF, and can surf the internet; the shared flow terminal user shares the flow to the shared flow terminal user; the shared flow terminal user uses the flow of the shared flow terminal user to surf the internet; in a specific implementation process, the PGW detects and judges the sharing behavior of the terminal user based on a corresponding relation table between the user number and the survival time value; after identifying the shared flow terminal user, reporting a shared event information relation table to the PCRF through a Credit Control Answer Update (CCA-U) message; then, the PCRF issues a differentiated control action (namely a control strategy) to the shared traffic terminal through the CCA-U message; therefore, the PGW performs differentiated control such as blocking, limiting speed or releasing on the shared traffic terminal. Then, the shared traffic terminal generates internet traffic. Since the steps in the figure have already been described in detail in the above, they are not described again here.
