Description

A shared traffic terminal identification method, device, device and readable storage medium

technical field

The present invention relates to the field of communication technologies, and in particular, to a shared traffic terminal identification method, apparatus, device and readable storage medium.

Background technique

With the rapid development of mobile network speed and smart terminals, user traffic demands are getting higher and higher. In order to meet the traffic demands of users, various operators have launched various large-traffic packages. During use, users who subscribe to a data package may share data for other end users by opening a terminal hotspot.

In the prior art, the method of identifying the shared traffic terminal through terminal information is often adopted. Specifically, by collecting the Internet access signaling list data of the target user number within a specific time period, the terminal information is extracted from the Internet access signaling list data. A judgment is performed on the terminal information to determine whether it is a shared traffic terminal. The terminal information includes a terminal model or an operating system version. More specifically, the terminal information is judged on the number of terminals that use the target user number to access the Internet within a specific time period to determine whether it is a shared traffic terminal. A terminal satisfying that the number of terminals is greater than or equal to 2 is determined as a shared traffic terminal.

However, in the process of adopting the above-mentioned method for identifying terminals for shared traffic, for the scenario of sharing to terminals of the same terminal model or the same operating system version, because the terminals of the same terminal model or the same operating system version are identified as the same terminal, the waiting The tested shared traffic terminal is misjudged as a non-shared traffic terminal; for another example, if the user changes the phone by himself, the terminal to be tested is originally a non-shared traffic terminal, but because different terminal signals or different operating system versions correspond to different terminals, the terminal to be tested is changed. The terminal is misjudged as a shared traffic terminal; for another example, for the one-number multi-terminal service scenario, the identification of the shared traffic terminal will be misjudged because the one-number multi-terminal service does not belong to the traffic sharing scenario.

It can be seen that the existing shared traffic terminal identification method has a technical problem of low accuracy.

Detailed ways

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 present invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor a separate or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

In order to better understand the above technical solutions, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It is not intended to limit the technical solutions of the present invention, and the embodiments of the present invention and the technical features in the embodiments may be combined with each other without conflict.

In the embodiment of the present invention, for the application scenario in which the shared traffic terminal opens a hotspot to the shared traffic terminal, it may specifically be a general packet radio service technology (General Packet Radio Service) GPRS, a third-generation mobile communication technology ( The 3-rd Generation Mobile Communication Technology) 3G, the 4th Generation Mobile Communication Technology (the 4th Generation Mobile Communication Technology) 4G, the 5th Generation Mobile Communication Technology (the 5th Generation Mobile Communication Technology) 5G signals are converted into wifi signals and sent out, The traffic corresponding to the wifi signal is used by other terminals other than the terminal, so that the shared traffic terminal can share the traffic to the shared traffic terminal. In order to improve the identification accuracy of the shared traffic terminal, a table based on the correspondence between the user number and the time-to-live value is provided to identify the shared traffic terminal. In a specific implementation process, the time-to-live value can represent the sharing behavior of the terminal, so that the identification accuracy of the terminal sharing traffic can be improved.

Referring to FIG. 1, an embodiment of the present invention provides a schematic flowchart of a method for identifying a shared traffic terminal, and the method specifically includes:

S101: Within a specific time period, split the original signaling packets from M terminals to be tested at the PGW side of the packet domain data core network gateway, where M is a positive integer;

S102: Parse the original signaling packet, and generate a correspondence table including the correspondence between the user number of each of the M terminals to be tested and the time-to-live value, wherein the time-to-live The value is used to limit the maximum number of hops that the Internet Protocol IP data packet in the original signaling message is forwarded in the network;

S103: According to the correspondence table, identify N terminals to be tested that meet the conditions among the M terminals to be tested as sharing traffic terminals, where N is a positive integer not greater than M.

In the specific implementation process, when the M terminals to be tested surf the Internet within a specific time period, the original signaling packets from the M terminals to be tested are split through the Packet Data Network Gateway (PGW) side. . Wherein, each terminal to be tested may be a personal computer (Personal Computer, PC), a tablet computer, a personal digital assistant (Personal Digital Assistant, PDA), a personal communication service (Personal Communication Service, PCS) phone, notebook and mobile phone and other terminal equipment , it can also be a computer with a mobile terminal, for example, it can be a portable, pocket-sized, hand-held, computer built-in or vehicle-mounted mobile device, or other terminal equipment that uses data traffic to access the Internet. In the implementation process, the specific time period can be 5 minutes, can also be 1 hour, or can be one or more days. Of course, those skilled in the art can set the specific time period according to the actual usage habits of users. Here I won't go into details. In a specific implementation process, the PGW stores the original signaling message locally after demultiplexing and processing the original signaling message from the M terminals to be tested. For those skilled in the art, the PGW performs optical splitting processing on the original signaling packet, that is, the PGW performs duplication processing on the original signaling packet.

Then, the original signaling message is parsed to generate a correspondence table including the correspondence between the user number of each of the M terminals to be tested and the time-to-live value (Time to live), wherein, The time-to-live value is used to limit the maximum number of hops that the Internet Protocol (Internet Protocol, IP) data packet in the original signaling packet is forwarded in the network. For a specific example, when the time period is 5 minutes, when 5 terminals to be tested correspond to 6 user numbers a to f in total, the generated correspondence table includes the user number a and at least one survival time in the time period. The corresponding relationship between the values, the corresponding relationship between the user number b and at least one time-to-live value in the time period, ..., the corresponding relationship between the user number f and at least one time-to-live value in the time period.

Then, according to the correspondence table, the N terminals to be tested that meet the conditions among the M terminals to be tested are identified as sharing traffic terminals, that is to say, the correspondence table is used as a judgment condition, from the M terminals to be tested Shared traffic endpoints are identified. In the specific implementation process, the time-to-live value is set to prevent the IP data packet from being forwarded infinitely in the network, and its characteristic value is used to tell the network how many times the IP data packet can be forwarded in the network. Once an IP packet is forwarded, the value corresponding to the time-to-live value of the IP packet must be decremented by 1. Since in the embodiment of the present invention, the shared traffic terminal is identified according to the lifetime value that can characterize the sharing behavior of the terminal, the identification accuracy of the shared traffic terminal can be effectively improved.

In the embodiment of the present invention, in order to realize the accurate identification of the shared traffic terminals, step S103: according to the corresponding relationship table, identify N qualified terminals to be tested among the M terminals to be tested as shared traffic terminals, Including: if the time-to-live value of each user number in the N terminals to be tested in the corresponding relationship table includes at least TTL and (TTL-n), identifying the N terminals to be tested as shared Traffic terminal, wherein 1≤n≤TTL, TTL and (TTL-n) are both used to characterize the specific characteristic value of the time-to-live value in the specific time period.

In a specific implementation process, when a terminal serving as a hotspot supports forwarding an IP data packet of a back-end device, the specific value TTL corresponding to the time-to-live value is reduced by 1. For example, the characteristic value of the time-to-live value of the IP header of the user's own traffic of terminal A is 64, and the characteristic value of the time-to-live value of the IP header after passing the shared traffic once is 63. As shown in Table 1, a schematic diagram of one of the eigenvalues of the time-to-live values of the shared traffic terminal and the shared traffic terminal under different operating systems (Android, IOS, WP, Windows) is shown. Specifically, it can be known that the eigenvalue of the time-to-live value after the shared traffic terminal shares the traffic once with the shared traffic terminal is reduced by 1 compared to the original eigenvalue.

Table 1

In the specific implementation process, for complex networking or complex scenarios where a relay server appears in the shared network, the specific value TTL corresponding to the time-to-live value by the back-end device may appear in the process of sharing traffic terminal identification minus n (where n is Integer greater than 1), it will inevitably lead to confusion in identification. 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 (wherein, 1≤n≤TTL). In the specific implementation process, if the time-to-live value of a certain user number in the corresponding relationship table includes the characteristic value TTL and at least one of {TTL-1, TTL-2, ..., TTL-n}, the The terminal to be detected corresponding to the user number is identified as a shared traffic terminal. For example, if the characteristic value corresponding to the time-to-live value of user number a in the correspondence table includes TTL and TTL-1, the terminal under test corresponding to the user number a is a shared traffic terminal; for another example, if user number b is in The characteristic values corresponding to the time-to-live values in the correspondence table include TTL, TTL-2, and TTL-3, and the terminal to be tested corresponding to the user number b is a shared traffic terminal. In the specific implementation process, when n is TTL, it indicates that before the IP data packet reaches the destination IP, the TTL is reduced to 0, and the router will discard the received IP data packet with TTL=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 : parse the original signaling packet, and generate a message including each terminal to be tested among the M terminals to be tested. The correspondence table of the correspondence between the user number of the terminal and the time-to-live value, including:

S201: Parse the original signaling message to obtain a user number of each terminal to be tested in the M terminals to be tested and a time-to-live value in a corresponding IP header;

S202: Generate a correspondence table including a correspondence between the subscriber number of each terminal to be tested and the time-to-live value.

In the specific implementation process, the specific implementation process of step S201 to step S202 is as follows:

First, the original signaling message is parsed to obtain the user number of each of the M terminals to be tested and the time-to-live value in the corresponding IP header. For example, the original signaling packet within 1 hour is parsed to obtain the user number of each terminal to be tested among the 100 terminals and the time-to-live value in the corresponding IP header. Then, a correspondence table including the correspondence between the subscriber number of each terminal to be tested and the time-to-live value is generated. For example, a correspondence table including 120 subscriber numbers and corresponding time-to-live values in the IP header among the 100 terminals is generated. For example, the correspondence table includes the user number a and the characteristic value set {TTL, TTL-1} of the corresponding time-to-live values, the user number b and the characteristic value set {TTL, TTL- 1. TTL-2, TTL-3}, the user number c and the characteristic value set {TTL, TTL-2, TTL-3, TTL-5} of the corresponding time-to-live value. Of course, in the specific implementation process, the corresponding relationship table is specifically changed in real time according to the specific situation of the user number and the corresponding survival time value in a specific time period, and details are not described here.

In this embodiment of the present invention, in order to achieve precise control of the shared traffic terminals, please refer to FIG. 3 , in step S103 : according to the corresponding relationship table, the N terminals to be tested that meet the conditions of the M terminals to be tested are sorted After being identified as a shared traffic terminal, the method further includes:

S301: Determine target user numbers corresponding to the N terminals to be tested;

S302: Generate a shared event information relationship table, wherein the shared event information relationship table includes at least the target user number, the specific time period, and a parsed data from the original signaling message for characterizing the The quality of service class identifier QCI value of the service level of the target subscriber number in the network;

S303: report the shared event information relationship table to the packet domain data core network policy and control server PCRF through the PGW;

S304: Receive a control policy generated by the PCRF based on the shared event information relationship table;

S305: Control the traffic sharing behavior of the N terminals to be tested according to the control policy.

In the specific implementation process, the specific implementation process of step S301 to step S305 is as follows:

First, after identifying N qualified terminals to be tested among the M terminals to be tested as shared traffic terminals, determine the target user numbers corresponding to the N terminals to be tested; then, generate a shared event information relationship table, wherein the The shared event information relationship table includes at least the target subscriber number, a specific time period, and a Quality of Service Class Identifier (Quality of ServiceClass Identifier) parsed from the original signaling message and used to characterize the service level of the target subscriber number in the network. ) QCI value. Generally, the smaller the QCI value, the higher the level, and vice versa. For example, set the QCI value of the target user number corresponding to VIP users to a higher level "QCI=1", and set the QCI value of the target user number corresponding to ordinary users to a lower level "QCI=6"; 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 of "QCI=5". Of course, those skilled in the art can set the specific value of the QCI value of the target subscriber number according to the actual usage habits of the user, which will not be repeated here.

Then, the shared event information relationship table is reported to the packet domain data core network policy and control server (Policy and Charging Rules Function) PCRF through the PGW. Then, the PCRF will generate a control strategy for the differentiated flow control of the shared traffic terminal under the shared traffic terminal based on the relevant parameters in the shared information relationship table; then, the PCRF will deliver the control strategy to the PGW, and the PGW will according to the The control policy performs differential control on the traffic sharing behavior of the shared traffic terminal under the shared traffic terminal.

In the embodiment of the present invention, step S305: controlling the traffic sharing behavior of the N terminals to be tested according to the control policy, including:

At least according to the specific time period and the QCI value, block, limit or release the shared traffic terminals of the target user number or a specific number of terminals.

In the specific implementation process, the PGW blocks, restricts or releases the shared traffic terminals of the target user number or a specific number of terminals according to at least the specific time period and the QCI value in the shared information relationship table. For example, the PGW assigns the shared traffic terminal corresponding to the target user number under each shared traffic terminal in the 10 shared traffic terminals in the afternoon from 13:00 to 14:00, or the shared traffic terminal of a specific number of terminals. Blocking, that is, the shared traffic terminals corresponding to these target user numbers, or the shared traffic terminals with a specific terminal data volume will not be able to access the Internet. More specifically, for example, the traffic of the shared traffic terminal corresponding to the user numbers b, c, and d of the shared traffic terminal A within this time period is blocked. For another example, the rate of traffic of any 5 shared traffic terminals under the shared traffic terminal B within this time period is limited. Of course, those skilled in the art can set the specific control method of the PGW for the traffic sharing behavior of the traffic sharing terminal according to the actual usage habits of the user, which will not be repeated here. In the embodiment of the present invention, based on the accurate identification of the shared traffic terminal based on the spectral detection on the PGW side, the PGW reports the shared event information relationship table to the PCRF, and then the PGW receives the PCRF and generates it based on the relevant parameters in the shared event information relationship table. It can block, limit or release the shared traffic terminals of the target user number or a specific number of terminals, so as to realize the differentiated control of hotspot sharing behavior and protect the network resources of the operator.

Based on the same inventive concept, an embodiment of the present invention provides a shared traffic terminal identification device. Since the principle of the above device for solving the problem is similar to the shared traffic terminal identification method, the implementation of the above device can refer to the implementation of the method, and the repetition is not repeated. Repeat.

FIG. 4 is a schematic diagram of the entire process of identifying and controlling shared traffic terminals in an embodiment of the present invention. Specifically, the shared traffic terminal user sends an Internet access request to the PGW; the PGW sends a Credit Control Request-Initial (CCR-I) message to the PCRF; the PCRF sends a Credit Control Answer-Initial (CCA-I) message to the PCRF. 1) message to the PGW; the shared traffic terminal user is activated successfully after the PCRF confirms that the response is normal, and can access the Internet; the shared traffic terminal user shares the traffic to the shared traffic terminal user; the shared traffic terminal user uses the shared traffic terminal user's Traffic Internet access; in the specific implementation process, the PGW detects and judges the sharing behavior of the end user based on the corresponding relationship table between the user number and the time-to-live value; Answer-Update, CCA-U) message reports the shared event information relationship table to PCRF; then, PCRF delivers differentiated control actions (that is, control policies) to the shared traffic terminal through the CCA-U message; Differentiated controls such as blocking, speed limiting or releasing are performed on shared traffic terminals. Then, the shared traffic terminal generates Internet traffic. Since each step in the figure has been described in detail in the above content, it will not be repeated here.
