Detailed Description
The embodiment of the invention provides a method and a device for judging the Internet surfing quality difference of an LTE user, which realize the evaluation of Internet surfing perception and quality difference judgment from a user level.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are for illustration and explanation only, and not for limitation of the present invention, and embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
In this context, it is to be understood that the technical terms referred to in the present invention are:
1. XDR (Expand Data Recording, extended data record) is a concept evolved from CDR (Call Data Recording, call data record), which is a record of network critical information during a call in a conventional communication network. XDR is an extension of the CDR concept and broadly refers to a critical information record, i.e., traffic log, for data traffic in a mobile network, a bearer network, with a session forming an XDR record in units of user sessions.
2. DPI is a deep detection technique based on data packets, which performs deep detection for different network application layer loads (e.g. HTTP, DNS (Domain Name System, domain name system), etc.), and determines the validity of the packet by detecting its payload. DPI is a technology that has been successful in traffic management, security, and network analysis, while enabling content analysis of network packets.
3. The S1 interface is a communication interface between the LTE base station eNodeB and the packet core network (EPC, evolved Packet Core), dividing the LTE system into a radio access network and a core network. The S1 interface inherits the idea of separating bearing and control, and is divided into two interfaces, one for the control plane: S1-MME, one for user plane: S1-U. The S1-U interface establishes a tunnel between a GW (gateway) and an eNodeB device, and conveys user data traffic, i.e., user plane data. Fig. 1 is a schematic diagram of connection between a radio side and a core side of an LTE system. The XDR ticket is collected at the S1-U interface.
As shown in fig. 2, which is a schematic implementation flow chart of a method for determining internet surfing quality difference of an LTE user according to an embodiment of the present invention, the method may include the following steps:
s11, collecting XDR call tickets generated by the LTE user surfing the Internet within a set time period.
In specific implementation, the DPI equipment collects XDR call tickets generated by the LTE user surfing the Internet within a set time period. Specifically, the DPI device collects an XDR ticket generated by the LTE user surfing the Internet in a set time period through an S1-U interface. The setting time may be set according to the needs, for example, 1 hour, which is not limited in the embodiment of the present invention.
And S12, extracting key field contents for each XDR record in the XDR ticket.
In specific implementation, the DPI device extracts key field content for each XDR record in the collected XDR ticket of the LTE user. The key fields comprise data flow, TCP (transmission control protocol) link establishment response time delay, TCP link establishment confirmation time delay, time delay from TCP link establishment success to first transaction request, first HTTP (hyper text transfer protocol) HTTP response packet time delay and time delay of last HTTP content packet. The TCP link establishment response time delay represents time delay between sending SYN information and receiving SYN+ACK information in the TCP three-way handshake process; the TCP link establishment acknowledgement time delay represents the time delay between sending SYN+ACK information and receiving the ACK information in the TCP three-way handshake process; the time delay from the successful TCP link establishment to the first transaction request represents the time delay from the last ACK message in the three-way handshake to the receipt of the first transaction request (such as HTTP get command); the first HTTP response packet delay represents a delay of the first HTTP response packet relative to the first HTTP request packet (e.g., HTTP get command); the last HTTP content packet's latency represents the last HTTP content packet's latency relative to the first HTTP request packet (e.g., HTTP get command).
Specifically, the data traffic is an upstream traffic or a downstream traffic, and whether the XDR record includes the upstream traffic or the downstream traffic can be determined by querying whether the XDR record includes a "Filename" code stream. If the Filename code stream is contained, determining that the XDR record contains downlink traffic; if the 'Filename' code stream is not contained, determining that the XDR record contains uplink traffic.

S22, judging whether the data transmission rate is greater than a second preset threshold value, and if the data transmission rate is less than or equal to the second preset threshold value, executing a step S23; if the data transmission rate is greater than a second preset threshold, step S24 is performed.
In the implementation, the data transmission rate is an uploading rate or a downloading rate, and if the XDR record contains uplink traffic, whether the corresponding uploading rate is greater than a second preset threshold value is judged; and if the XDR records contain downlink flow, judging whether the corresponding downloading rate is greater than a second preset threshold value. The second preset threshold may be, but is not limited to, 500KB.

Specifically, the upload rate (i.e., the uplink rate) may be determined by the following formula:
Upstream traffic (KB) 8/time delay (ms) of last HTTP content packet
The download rate (i.e., downstream rate) may be determined by the following equation:
downstream traffic (KB) 8/time delay (ms) of last HTTP content packet
S23, judging the XDR record as a large packet rate quality difference service ticket record.

In the implementation, determining the wireless side time delay through the TCP link establishment confirmation time delay and the time delay from the successful TCP link establishment to the first transaction request; and determining the core side delay through the TCP link establishment response delay and the first HTTP response packet delay. The wireless side delay is delay of an LTE system base station (eNodeB) side, and the core side delay is delay of a packet core network (EPC) side.
Specifically, the wireless side delay may be determined by the following formula:
wireless side delay = TCP build acknowledgement delay + delay until the first transaction request is successful.
The core side delay may be determined by the following formula:
core side delay = TCP build response delay + first HTTP response packet delay to determine core side delay.
In the embodiment of the invention, the third preset threshold and the fourth preset threshold can be determined according to empirical values, for example, the values of the third preset threshold and the fourth preset threshold can be determined according to distribution statistics of time delays of all sections of the internet surfing service of the LTE user and a 'two-eight principle' obtained when the satisfaction degree investigation data of the LTE internet surfing user of the Beijing company is larger than a set threshold (for example, 79 minutes). For example, as shown in fig. 4 and fig. 5, the statistical core-side delay distribution data schematic diagram and the wireless-side delay distribution data schematic diagram of the user satisfaction degree of the LTE internet surfing of beijing company are 79 time-sharing respectively. As shown in fig. 4, the core side delay of 80% of the users is less than 154ms, and as shown in fig. 5, the radio side delay of 80% of the users is less than 232ms, and then the third preset threshold may be 232ms, and the fourth preset threshold may be 154ms.
