Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a readable storage medium for identifying a shared traffic terminal.
Background
With the rapid development of mobile network speed and intelligent terminals, the user traffic demand is increasing. To meet the traffic demands of users, various high-traffic packages are introduced by various operators. In the use process, the user ordering the traffic package can share traffic to other terminal users by opening the terminal hot spot.
In the prior art, a method of identifying a shared traffic terminal through terminal information is often adopted, specifically, by collecting internet surfing signaling list data of a target user number in a specific time period, extracting terminal information from the internet surfing signaling list data, and judging the terminal information to determine whether the shared traffic terminal is the shared traffic terminal. Wherein the terminal information includes a terminal model or an operating system version. More specifically, the terminal information is determined to determine whether it is a shared traffic terminal by determining the number of terminals that are surfing the internet using the target user number within a specific time period. And determining the terminals meeting the terminal number of more than or equal to 2 as shared flow terminals.
However, in the process of adopting the above-mentioned shared traffic terminal identification method, for the scenario of sharing to the same terminal model or the same operating system version terminal, the shared traffic terminal to be tested is misjudged as a non-shared traffic terminal because the terminal of the same terminal model or the same operating system version is identified as the same terminal; for another example, the user changes the terminal to be tested into a non-shared traffic terminal by himself, but because different terminal signals or different operating system versions correspond to different terminals, the terminal to be tested is misjudged as a shared traffic terminal; for another example, for a one-number multi-terminal service scenario, misjudgment may occur in identifying a shared traffic terminal, because the one-number multi-terminal service does not belong to the traffic sharing scenario.

Detailed Description
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the invention. The appearances of such phrases 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. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
In order to better understand the above technical solutions, the following detailed description of the technical solutions of the present invention is made by using the accompanying drawings and specific embodiments, and it should be understood that the specific features of the embodiments and the embodiments of the present invention are detailed descriptions of the technical solutions of the present invention, and not limiting the technical solutions of the present invention, and the embodiments and the technical features of the embodiments of the present invention may be combined with each other without conflict.
In the embodiment of the invention, aiming at the application scenario that a shared flow terminal opens a hot spot to a shared flow terminal, the method specifically can convert the signals of 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, 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 received by the terminal into wifi signals to be sent out, so that other terminals outside the terminal can use the flows corresponding to the wifi signals, and the shared flow terminal can share the flows to the shared flow terminal. In order to improve the identification accuracy of the shared flow terminal, the identification of the shared flow terminal is performed based on a corresponding relation table between the user number and the survival time value. In the implementation process, the survival time value can represent the sharing behavior of the terminal, so that the identification accuracy of the shared flow terminal can be improved.
Referring to fig. 1, an embodiment of the present invention provides a flow chart of a method for identifying a shared traffic terminal, where the method specifically includes:
s101: in a specific time period, splitting original signaling messages from M terminals to be tested at the 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 the corresponding relation between the user number of each to-be-tested terminal in the M to-be-tested terminals and a survival time value, wherein the survival time value is used for limiting the maximum hop count of the Internet Protocol (IP) data packet in the original signaling message forwarded in a network;
s103: and identifying N terminals to be detected meeting the conditions in the M terminals to be detected as shared flow terminals according to the corresponding relation table, wherein N is a positive integer not greater than M.
In the specific implementation process, when M terminals to be tested surf the internet in a specific time period, original signaling messages from the M terminals to be tested are split through a packet domain data core network gateway (Packet Data Network Gateway, PGW) side. Each terminal to be tested may be a terminal device such as 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, a notebook, a mobile phone, or the like, or may be a computer with a mobile terminal, for example, a portable, pocket, hand-held, built-in or vehicle-mounted mobile device of the computer, or other terminal devices that use data traffic to access the internet. In the implementation process, the specific time period may be specifically 5min, 1 hour, or one or more days, and of course, those skilled in the art may set the specific time period according to the actual usage habits of the user, which will not be described herein. In a specific implementation process, after the PGW performs beam splitting processing on original signaling messages from M terminals to be tested, the original signaling messages are stored locally. It is obvious to those skilled in the art that the PGW performs a beam splitting process on the original signaling message, that is, the PGW performs a copying process on the original signaling message.
And then, analyzing the original signaling message to generate a corresponding relation table comprising the corresponding relation between the user number of each to-be-tested terminal in the M to-be-tested terminals and a Time to live value (Time to live), wherein the Time to live value is used for limiting the maximum hop count of the internet protocol (Internet Protocol, IP) data packet forwarded in the network in the original signaling message. For a specific example, when the time period is 5min and the 5 terminals to be tested correspond to a to f and total 6 user numbers, the generated corresponding relation table includes the corresponding relation between the user number a and at least one survival time value in the time period, the corresponding relation between the user number b and at least one survival time value in the time period, … …, and the corresponding relation between the user number f and at least one survival time value in the time period.
And then, according to the corresponding relation table, identifying the N terminals to be detected meeting the conditions in the M terminals to be detected as shared traffic terminals, namely, identifying the shared traffic terminals from the M terminals to be detected by taking the corresponding relation table as a judgment condition. In the implementation process, the lifetime value is set to prevent the IP data packet from being forwarded infinitely in the network, and the characteristic value is used to tell the network how many times the IP data packet can be forwarded in the network, and the router subtracts 1 from the value corresponding to the lifetime value of the IP data packet once for each forwarding of the IP data packet. In the embodiment of the invention, the shared flow terminal is identified according to the survival time value capable of representing the sharing behavior of the terminal, so that the identification accuracy of the shared flow terminal can be effectively improved.
In the embodiment of the present invention, in order to realize accurate identification of the shared traffic terminal, step S103: according to the corresponding relation table, identifying the N terminals to be detected meeting the conditions in the M terminals to be detected as shared flow terminals, including: and if the survival time value of each user number in the N terminals to be detected in the corresponding relation table at least comprises TTL and (TTL-N), identifying the N terminals to be detected as shared flow terminals, wherein N is more than or equal to 1 and less than or equal to TTL, and the TTL and (TTL-N) are used for representing specific characteristic values of the survival time value in the specific time period.
In the implementation process, when the terminal serving as the hot spot supports forwarding the IP data packet of the back-end equipment, the specific numerical value TTL corresponding to the survival time value is reduced by 1. For example, the characteristic value of the lifetime value of the IP header of the user of the terminal a is 64, and the characteristic value of the lifetime value of the IP header after one-time sharing of the traffic is 63. Table 1 shows one of the characteristic values of the lifetime values of the shared traffic terminals and the shared traffic terminals under different operating systems (Android, IOS, WP, windows). Specifically, the characteristic value of the lifetime value obtained by sharing the flow once by the shared flow terminal is subtracted by 1 from the original characteristic value.
TABLE 1
In the specific implementation process, for complex scenes of networking complexity or a relay server in the middle of a shared network, the situation that the specific numerical value TTL corresponding to the survival time value of the back-end equipment is subtracted by n (where n is an integer greater than 1) may occur in the process of identifying the shared flow terminal, so that confusion in identification is unavoidable. Therefore, in the implementation process, the shared flow terminal is identified by identifying the characteristic value (TTL-n) corresponding to the time-to-live value (wherein, 1 is less than or equal to n is less than or equal to TTL). In the implementation process, if the survival time value of a user number in the corresponding relation table includes a feature value TTL and at least one of { TTL-1, TTL-2, … …, TTL-n }, identifying the terminal to be detected corresponding to the user number as a shared flow terminal. For example, if the characteristic value corresponding to the survival time value of the user number a in the corresponding relation table includes TTL and TTL-1, the terminal to be tested corresponding to the user number a is a shared flow terminal; for another example, if the characteristic value corresponding to the survival time value of the user number b in the corresponding relation table includes TTL, TTL-2 and TTL-3, the terminal to be tested corresponding to the user number b is a shared traffic terminal. In the 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 will discard the received IP 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: 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 of 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 survival time value in the corresponding 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 implementation process, the specific implementation process of 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 head. For example, the original signaling message within 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 including 120 user numbers and corresponding lifetime values in the IP header is generated in the 100 terminals. For example, the correspondence table includes a user number a and a feature value set { TTL, TTL-1} of the corresponding time-to-live values, a user number b and a feature value set { TTL, TTL-1, TTL-2, TTL-3} of the corresponding time-to-live values, and a user number c and a feature value set { TTL, TTL-2, TTL-3, TTL-5} of the corresponding time-to-live values. Of course, in the implementation process, the corresponding relation table specifically changes in real time according to the specific situation of the user number and the corresponding survival time value in the specific time period, which is not described herein again.
In the embodiment of the present invention, in order to realize accurate control of the shared traffic terminal, please refer to fig. 3, in step S103: after identifying the N terminals to be detected, which meet the conditions, of the M terminals to be detected as 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 used for representing the service level of the target user number in a network;
s303: reporting the shared event information relation table to a policy and control server PCRF of a packet domain data core network through the PGW;
s304: receiving a control policy generated by the PCRF based on the shared 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 implementation process, the implementation process of step S301 to step S305 is as follows:
firstly, after N terminals to be detected meeting the conditions in M terminals to be detected are identified as shared flow terminals, determining target user numbers corresponding to the N terminals to be detected; a shared event information relationship table is then generated, wherein the shared event information relationship table includes at least the target user number, a specific time period, and a quality of service class identifier (Quality of Service Class Identifier) QCI value parsed from the original signaling message to characterize the service class of the target user number in the network. Generally, the smaller the QCI value, the higher the corresponding level, and vice versa. For example, the QCI value of the target user number corresponding to the VIP user is set to a higher level "qci=1", and the QCI value of the target user number corresponding to the normal user is set to a lower level "qci=6"; for another example, the QCI value of the internet service of the target user number is set to a higher level "qci=3", and the QCI value of the telephone service of the target user number is set to a lower level "qci=5". Of course, the specific value of the QCI value of the target subscriber number can be set by those skilled in the art according to the actual usage habit of the subscriber, and will not be described herein.
The shared event information relationship table is then reported by the PGW to a packet domain data core network policy and control server (Policy and Charging Rules Function) PCRF. Then, the PCRF generates a control strategy for differentiated flow control of the shared flow terminal under the shared flow terminal based on the related parameters in the shared information relation table; and then, the PCRF issues the control strategy to the PGW, and the PGW performs differential control on the flow sharing behavior of the shared flow terminal under the shared flow terminal according to the control strategy.
In the embodiment of the present invention, step S305: controlling flow sharing behaviors of the N terminals to be tested according to the control strategy, wherein the flow sharing behaviors comprise:
and blocking, limiting or releasing the shared flow terminals of the target user number or the specific terminal number at least according to the specific time period and the QCI value.
In the implementation process, the PGW blocks, limits speed or puts through the shared flow terminals of the target user number or the specific terminal number according to at least the specific time period and QCI value in the shared information relation table. For example, the PGW blocks the shared traffic terminals corresponding to the target user numbers or the shared traffic terminals of the specific number of terminals in each of the 10 shared traffic terminals in the period of 13:00-14:00 pm, that is, the shared traffic terminals corresponding to the target user numbers or the shared traffic terminals of the specific terminal data amount will not be networked. More specifically, for example, the traffic of the shared traffic terminal corresponding to the user numbers b, c, and d in the shared traffic terminal a in the period of time is blocked. For another example, the traffic of any 5 shared traffic terminals B in the shared traffic terminal B in this period is limited. Of course, a specific control method of the PGW on the flow sharing behavior of the shared flow terminal may be set by a person skilled in the art according to the actual usage habit of the user, which is not described herein. In the embodiment of the invention, the shared flow terminals are accurately identified based on the spectroscopic detection at the PGW side, the PGW reports the shared event information relation table to the PCRF, and then the PGW receives the control strategy generated by the PCRF based on the related parameters in the shared event information relation table, and blocks, limits the speed or puts through the shared flow terminals with the target user numbers or the specific terminal numbers, thereby realizing the differential control of hot spot sharing behaviors 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 device, and because the principle of the device for solving the problem is similar to that of the shared traffic terminal identification method, the implementation of the device can refer to the implementation of the method, and the repetition is omitted.
Fig. 4 is a schematic diagram illustrating the overall process of identifying and controlling the shared traffic terminals according to an embodiment of the present invention. Specifically, the shared flow end user sends a surfing request to the PGW; the PGW sends a credit control request initiation (Credit Control Request-Initial, CCR-I) message to the PCRF; the PCRF transmits a control response Initial (Credit Control Answer-Initial, CCA-I) message to the PGW; the shared flow terminal user is activated successfully after the PCRF confirms that the response is normal, and can surf the internet; the shared flow end user shares the flow to the shared flow end user; the shared flow end user uses the flow of the shared flow end user to surf the internet; in the 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 the shared flow end user is identified, reporting a shared event information relation table to the PCRF through a credit control response Update (Credit Control Answer-Update, CCA-U) message; then, the PCRF issues differentiated control actions (namely control strategies) to the shared flow terminal through the CCA-U message; thus, the PGW performs differential control such as blocking, speed limiting or releasing on the shared flow terminal. The shared traffic terminal then generates the internet traffic. Since each step in the figure is already described in detail in the foregoing, a detailed description is omitted here.
