Detailed Description
The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. The technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the embodiments described are only some embodiments of the present disclosure, rather than all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The terms "first", "second", and the like are used hereinafter only for descriptive distinction and not for other specific meanings.
Fig. 1 is a flowchart illustrating a backward QoS securing method according to an embodiment of the present disclosure, as shown in fig. 1:
And 102, the AF generates a QoS setting request based on the QoS guarantee application, and sends the QoS setting request to a base station to which the terminal belongs through a core network.
And 103, after determining that the base station sets the QoS guarantee for the terminal according to the QoS setting request, the AF acquires QoS detection equipment corresponding to the terminal and controls the QoS detection equipment to initiate QoS active detection. The QoS guarantee set for the terminal comprises a special bearer guarantee and the like.
And step 104, the AF acquires a detection result and performs related operation on the set QoS guarantee based on the detection result. The relevant operations performed on the set QoS guarantee can be QoS tracking, analysis, charging, planning, business analysis, pricing and the like.
The backward QoS guarantee method in the embodiment can more accurately perform product charging, operation analysis, pricing and the like by actively detecting and tracking the guaranteed user QoS when the user QoS is guaranteed; meanwhile, the detection result can be used for wireless optimization of high-value users by an operator wireless network optimization department, and can also be used for base station capacity expansion, point selection, optimization and the like based on the high-value users by an operator wireless planning department.
In one embodiment, the AF records the corresponding user ID of the terminal, and determines the home area of the user ID. And the AF initiates polling call to the PCRF in the home region and sends a QoS setting request. The PCRF (Policy and Charging Rules Function) is a Policy and Charging control Policy decision point for traffic data flow and IP bearer resources.
The AF subscribes to the position information of the PCRF. And when receiving a return message of the PCRF to the QoS setting request, recording QoS guarantee information reported by the PCRF. The QoS guarantee information reported by the PCRF includes: PCRF information to which the terminal belongs, PGW information to which the terminal belongs, location information of the terminal, and the like. After establishing QoS guarantee for a user successfully, the AF records information of a user such as an attribution PGW, a private network IP and the like and position information of the user.
And the home PCRF of the user ID identifies the QoS setting request and sends the QoS setting request to the PDN gateway PGW. A PGW (PDN GateWay) is an important network element in the EPC of a mobile communication network. And the PGW determines an evolved node B eNB to which the terminal belongs based on the user online information, and generates a QoS instruction according to the QoS setting request and sends the QoS instruction to the eNB. The QoS guarantee application comprises the following steps: qoS acceleration application or deceleration application, etc. And the eNB establishes or stops the special bearing guarantee for the terminal based on the QoS instruction.
In one embodiment, the QoS probing devices are mounted under each PGW device in the existing network. The QoS detection equipment can acquire a private network IP in the PGW, can reach 4G equipment in the PGW jurisdiction, and can also communicate with the acceleration platform AF through a VPN or a DCN network.
The QoS detection equipment can be mounted under each PGW of each province, when the SP initiates QoS speed-up application/speed-down application to the AF, the AF records the user Id, calls the Id and calculates the province to which the user belongs, initiates polling speed-up call to all PCRFs of the province, subscribes position information, and records the information of the PCRF to which the information belongs when the information returns. Only the PCRF to which the user terminal belongs can successfully identify the message, and the speed-up request is continuously transmitted through the PGW. And the PGW finds the ENB of the user according to the user online information and issues a QoS instruction.
Fig. 2 is a schematic flowchart of tracking in an embodiment of a backward QoS securing method according to the present disclosure, as shown in fig. 2:
in step 201, the af obtains the QoS detection device mounted under the PGW to which the terminal belongs, and controls the QoS detection device to send a test message to the terminal and receive a test response message.
The test message may be various, such as a Ping message. The Ping message is one of ICMP messages, and is used to check whether the network is smooth or the network connection speed. And the Ping message sent by the QoS detection equipment reaches the terminal, and the terminal returns a response message for the Ping message to the QoS detection equipment.
In step 202, the af receives the detection result information periodically sent by the QoS detection device.
And the AF acquires the detection result information calculated by the QoS detection equipment according to the test message and the test response message. The detection result information includes: time delay Tr avg Packet loss plr, jitter avg Bandwidth BW avg 。
In an embodiment, the AF acquires a QoS detection device mounted under a PGW to which the user belongs, and controls the QoS detection device to initiate ping detection for the user terminal. The ping detection message finally reaches the user terminal through the PCRF, the PGW and the MME, and the user terminal returns a response message. After receiving the response message returned by the terminal device, the QoS detection device may calculate an air interface uplink and downlink Round Trip Time TR (Round Trip Time) from the base station to the terminal device:
Tr＝T arrive -T send (1－1)；
wherein, T send Indicating the ping packetTime of transmission, T arrive And the time of the QoS detection equipment receiving the response packet of the data packet returned by the terminal equipment is represented.
The QoS detection equipment sends n data packets to the terminal equipment and receives a response data packet returned by the terminal equipment. Receiving m response packets within a specified time, at this time, calculating a packet loss ratio plr from the probe device to the terminal device as follows:
plr＝(n-m)/n (1－2)；
from the size s of each packet and Tr of the packet, the transmission rate of the packet can be calculated:
br(i)＝s/Tr (1－3)；
for m received packets, the average bandwidth of the current link can be calculated:
the jitter value jitter (i) of the arrival time of the adjacent packet can be calculated according to the Tr time of the adjacent packet, and the calculation of the specific jitter can adopt various existing methods.
The average round trip time Tr and the packet loss rate plr are the main evaluation dimensions of the QoS of the user. When Tr is large, the user will feel a noticeable delay; a larger plr will result in a significant stuck. jitter avg Large jitter can create a time-and-time-out irregular experience for the network. Average bandwidth BW avg The guarantee requirement is not met, and the user feels periodic unsmooth.
And step 203, the AF associates the detection result information with the ticket, the user ID and the position information and carries out related operation. The related operations include: and tracking, charging, analyzing and the like are carried out on the set QoS guarantee. And the QoS detection equipment records the detection result information and periodically sends the detection result information to the AF. The AF can associate the detection result information with the user and the ticket through the message ID and the user ID, thereby realizing charging, analysis and the like based on the guarantee effect. And the AF correlates the detection result information with the geographical position of the base station, counts the QoS quality data of the terminal under the base station and is used for optimizing the wireless network and planning the site selection of the base station. The detection result information (QoS guarantee information) is associated with the geographical position of the base station, so that the QoS condition of a user under the base station can be counted.
When the QoS provisioning set for the terminal is ended and a preset time period (e.g., 10 minutes or the like) elapses, the AF sends an end probe instruction to the QoS probe device. And the AF acquires first detection result information before the QoS guarantee is finished and acquires second detection result information in a period from the QoS guarantee to the detection finish. And the AF performs QoS quality comparison before and after guarantee based on the first detection result information and the second detection result information, and evaluates the QoS quality.
The backward QoS guarantee method, the acceleration platform and the communication system in the embodiment utilize the accessibility characteristics of the IP and the port of the equipment in the same private network, actively carry out QoS tracking in real time through the QoS detection equipment, prevent data cheating of a third party and improve the accuracy and the effectiveness of data; dynamic interaction among the acceleration platform AF, the downstream equipment PCRF and the quality detection equipment is utilized, so that users are dynamically monitored and guaranteed as required, and the scale, difficulty and cost of deployment are reduced; the mode of server detection is adopted, and the implementation is easier compared with the mode of client detection; more valuable information can be detected through the comprehensive association with the user data and the position data, and the method can be used for the charging and the analysis of QoS products, network optimization, base station planning and the like.

And the PGW determines an evolved node B eNB to which the terminal belongs based on the user online information, and generates a QoS instruction according to the QoS setting request and sends the QoS instruction to the eNB.
