In this embodiment, the measurer inputs the number of the user to be measured, and the server automatically matches the number of the user to be measured with the number of the network user, so as to query the monitoring delay, the TCP confirmation time, the performance measurement delay, and the TCP response time.
Furthermore, a measurer can input a user number to be measured and a time point, and the server can inquire the monitoring time delay, the TCP confirmation time, the performance measurement time delay and the TCP response time of the user number at the time point, so that the measurement efficiency is further improved.
In this embodiment, the transmission delay is a delay between a 5G base station and a core network System Architecture Evolution Gateway (SAEGW), and the IPPM technology is used to implement real-time analysis of the transmission delay. Specifically, the core network SAEGW sends a first message to the 5G base station according to a specified period, where the first message carries the packet number and byte number of the service packet sent by the current statistics and the sending time T1 of the first message; the 5G base station sends a second message to the core network SAEGW after receiving the first message, wherein the second message carries the time T2 when the 5G base station receives the first message, the sending time T1 of the first message and the sending time T3 of the second message; after receiving the second message, the core network SAEGW records and stores the time T4 of receiving the second message, and calculates the transmission delay B according to the formula B (T4-T1) - (T3-T2) based on T1, T2, T3 and T4, that is: the value of the IPPM DELAY field in the 5G General DELAY table. As an alternative, the first message is an FM message and the second message is a BR message.
And step 216, subtracting the monitoring time delay from the TCP confirmation time to generate the wireless time delay.
In this embodiment, the wireless delay is a delay between the ue and the 5G base station. Using a TCP three-way handshake model, calculating a radio delay a according to a formula of (T6-T5) -B, where a is the radio delay, T6 is a time point from the core network SAEGW to the time point when the acknowledgment message is received, T5 is a time point when the request message is sent, (T6-T5) is the TCP acknowledgment time, and B is the transmission delay (monitor delay).
And 217, subtracting the monitoring time delay from the performance measurement time delay to generate the core network time delay.
In this embodiment, the core network latency is a latency between the core network SAEGW and a core network switch (core switch). The 5G base station sends a test message to the core switch through a TWAMP technology, wherein the test message comprises a test message, a first message sequence number S1 and a sending time timestamp T7; the core switch receives the test message sent by the 5G base station, records and stores the receiving time T8, extracts the first message sequence number S1 and the sending time timestamp T7, and simultaneously generates a response message; the core switch sends a response message to the 5G base station, wherein the response message comprises a response message, a second message sequence number S2 and a sending time timestamp T9; and the 5G base station receives the response message, records the receiving time T10 and calculates the number of the received messages. And calculating the core network delay C according to the formulas C [ (T10-T7) - (T9-T8) ] -B from T7, T8, T9 and T10. Wherein [ (T10-T7) - (T9-T8) ] is the value of TWAMP DELAY field in 5G General DELAY table.
In this embodiment, step 218 specifically includes:
step 2181, subtract TWAMP DELAY and IPPM DELAY to generate the delay difference.
And a step 2182 of subtracting the delay difference from the TCP Response Time to generate the Internet delay.
In this embodiment, the internet delay is a delay between the core switch and an internet Server (SP Server). By using a TCP three-way handshake model, an internet time delay D is calculated by a formula D (T12-T11) -C, wherein D is an internet Server time delay, C is a core network time delay, T12 is a time point when a core network SAEGW receives an acknowledgement message sent by an SP Server, T11 is a time point when the core network SAEGW sends a request message to the SP Server, and (T12-T11) is a time delay between the core network SAEGW and the SP Server.
In this embodiment, the total time delay is a time delay when the user terminal accesses the internet service, that is: the time from the user terminal initiating the service request to the user terminal receiving the SP Server response. According to the 5G network architecture, the total time delay comprises four parts of wireless time delay, transmission time delay, core network time delay and internet time delay.
Fig. 3 is a schematic structural diagram of a 5G network architecture according to an embodiment of the present invention, where the network architecture includes a user terminal 1, a base station 2, a core network SAEGW 3, a core switch4, and an SP Server 5. The user terminal 1 is in communication connection with the base station 2, and the time delay consumed by communication is wireless time delay A; the base station 2 is in communication connection with a core network SAEGW 3, and the time delay consumed by communication is transmission time delay B; the core network SAEGW 3 is in communication connection with the core switch4, and the communication time delay is the core network time delay C; the core switch4 is in communication connection with the SP Server 5, and the communication time delay is the Internet time delay D.
