Detailed Description
The following briefly introduces some concepts related to embodiments of the present application.
In the LTE system, compared with the third generation communication technology (3rd-generation,3G), the concept of "always on" is proposed in order to improve user experience and reduce service establishment delay. One bearer that is established when the UE and the network complete the attachment is called the default bearer. When a UE has a specific data flow to transmit and needs to reserve a dedicated radio bearer for transmission, the bearer is established as a dedicated bearer. After the dedicated bearer is established, the original default bearer should actually be a bearer channel with a lower priority.
In a Public Data Network (PDN) link, there is only one default bearer, but there may be multiple dedicated bearers. Generally, a user establishes a maximum of 11 bearers. Whenever the UE requests a new service, the serving gateway (S-GW)/PDN Gateway (PGW) receives policy rules from the policy and charging function (PCRF), which includes the quality of service (QoS) required by the service. If the default bearer cannot provide the required QoS, an additional bearer service, i.e., a dedicated bearer is established to provide the service, is required.
As shown in fig. 1, a method for bearer evaluation provided in this embodiment of the present application is applied to a bearer evaluation system composed of a test client 12, a test server 11, and a network device 13, where the test server 11 and the network device 13 together form an operator network test system. The test server 11 is deployed in an operator network, and the test client 12 and the test server 11 transmit a service flow through an established dedicated bearer, and then evaluate the service performance of the dedicated bearer based on the test client 12 and the test server 11.
The test server 11 includes a communication unit 114, a dedicated bearer calling unit 113, an emulated traffic flow generating unit 112, and a system management unit 111. The communication unit 114 is used for communication with the test client 12, protocol adaptation, transceiving of test data packets, access verification of the test client 12, and the like; the dedicated bearer invoking unit 113 is configured to send a request for establishing a dedicated bearer to an Application Function (AF) according to a test request sent by the test client 12, and process a response of the AF to the dedicated bearer invocation; the simulation service flow generating unit 112 is configured to generate a simulation service flow according to the captured real service flow; the system management unit 111 is used for test server 11 system management and maintenance.
The test client 12 includes a real traffic flow capturing unit 121, a communication unit 123, a test template determining unit 122, a result displaying unit 124, and a system managing unit 125. The real traffic capturing unit 121 is configured to capture a data packet of a real traffic during the terminal runs an application; the communication unit 123 is used for communication with the test server 11, protocol adaptation, transceiving of test data packets, access verification of the test client 12, and the like; the test template determination unit 122 is configured to select a matching test template; the result display unit 124 is used for displaying the test result; the management unit 125 is used for overall test client 12 system management and maintenance, and test template management.
The AF in the network device 13 is responsible for communicating with the PCRF, interacting with information such as dynamic sessions, and is usually deployed in the form of a service platform.
Further, the test server 11 may be set up independently, or may be integrated with other network devices, for example, may be integrated with AF. The test client 12 may be provided integrally with the hardware network device.
As shown in fig. 2, the method specifically includes the following steps:
s101, the test client captures a real service flow and sends the real service flow to a test server.
For example, as shown in fig. 3, a tester logs in a proprietary account password through a third party Application (APP) of a smart phone at a test client to obtain authentication of a test server. Starting a real service capturing process at a test client, determining captured real service flow according to the requirements of testers, selecting an application of the real service flow to be captured according to the captured real service flow, and filtering out a target test service flow through the application. For example, when the delay evaluation of the royal of the client terminal needs to be detected, a tester selects a bag capturing parameter for capturing the royal glory at a test client; when the evaluation of the code stream rate of the panning of the client terminal needs to be detected, a tester selects to capture the code stream rate parameter of the panning at a test client. When the captured real service flow meets the requirements of the tester, the tester manually closes the application for capturing the real service flow, ends the process of capturing the real service flow and stores the information of the captured data packet. And the test client uploads the captured real service packet to the test server.
Furthermore, when the royal is glory to grab the package, the tester grabs the complete service flow of one part, and then edits and clips the complete service flow grab package according to the test requirement to obtain the service flow of the required time period. For example, when a game service flow is obtained, according to the actual situation of the game, a period of time when the game starts is provided, the requirement of the game client on the service quality of the game is low, and a tester can directly jump to the time when the game is opened for 3 minutes to start to catch the game without catching the game; when the team fighting business flow is obtained, the two parties of the royal glory middle red and blue play a team, the game client has high requirement on the service quality of the game, the tester can start to grab the package from a period of time after the team fighting starts, the grabbing stops after the team fighting is finished, and then a small number of packages are grabbed, the service quality required by the whole royal glory game is reflected, the process of respectively testing by using various applications at present is simplified, and the testing efficiency is improved.
S102, the test client sends the real service flow to the test server, and the test server generates at least one simulation service flow according to the real service flow.
The test server acquires a real service flow; the test server determines the service characteristics of the real service flow; and the test server generates at least one simulation service flow according to the service characteristics of the real service flow.
Illustratively, the test client captures a packet of the real service flow, the captured packet is encrypted, and the test server cannot recover the original packet of the real service flow. At this time, the test server can simulate the packet of the original service flow by using the same protocol and the same packet size, and then simulate the packet of the original real service flow by combining the fluctuation condition of the real service flow of the captured packet. The testing server can also generate a predicted simulation service flow according to the trend characteristics of the real service flow, for example, a tester can predict the jitter real service flow characteristics of the next section of royal glory through the trend characteristics of the obtained jitter real service flow of the small section of royal glory by the testing server, and then the testing server generates the simulation service flow according to the predicted jitter real service flow characteristics of the royal glory.
S103, the test client determines a target test template corresponding to the simulation service flow and sends the target test template to the test server.
The template comprises basic test template information, test client matching information, test service flow information, whether to call a special bearer, whether to perform concurrent test on a plurality of clients and the like.
And in order to complete the preparation work before the evaluation, the smooth operation of evaluating the service performance of the special bearer is ensured. Before the test server evaluates the service performance of the special bearer according to the target test template, the test client detects whether the target test template downloaded from the test server is received, and if not, the target test template is downloaded from the test server.
Illustratively, as shown in fig. 4, the basic information of the test template includes: template identification (Identity, ID), name, creation account number, and creation date; the testing of the client matching information comprises: brand, model, and operating system version; testing the client matching information: name, transmission direction and transmission protocol. Specifically, the ID in the basic information of the test template is a Rong Yao battle 1 bale, the name is a Rong Yao bale application simulation service flow, and the creator account is Wangzherongyao; the brand in the matching information of the test client is 11(iphone), the model is 0 (model more than 6S), and the operating system is 0 (all versions); the name in the test service flow information is a test service flow A of the royal glory packet application, the transmission direction is bidirectional transmission, and the transmission Protocol is a User Data Protocol (UDP); calling a special bearer; non-multi-terminal concurrent testing.
Further, the test client stores at least one test template; the method for determining the target test template corresponding to the simulation service flow by the test client comprises the following steps: the test client side matches in the at least one test template according to keywords input by a user; the keyword is used for representing the simulation service flow; if the test template matched with the keyword exists, determining the matched test template as a target test template; and if the test template matched with the keyword does not exist, establishing the target test template according to the real service flow.
For example, as shown in fig. 5, when a tester captures a royal glory packet application test service flow a, a "royal glory packet application test service flow a" is directly input at a test service flow information name of a test client template, a test client matches the "royal glory packet application test service flow a" input by a user in a test template library, and when a test template matching the "royal glory packet application test service flow a" exists, a template with ID of royal glory packet fighting 1 packet is selected as a target test template; when the test template matched with the Wang glory bale plucking application test service flow A does not exist, the tester is prompted to establish a new target template. When a tester needs to repeatedly measure the same real data stream, the matched template can be directly sent to the test server through the test client only by selecting the template matched with the real service stream of the target to be tested, so that the measurement evaluation is carried out, the time is saved, the influence of manual input of test parameters on the accuracy of a test result is reduced, and the test efficiency is improved.
S104, the test server determines a target simulation service flow from at least one simulation service flow according to the target test template.
Specifically, the test server reads the information on the template according to the received target test template, and determines the target simulation service flow to be tested.
S105, the test client sends the simulation service flow to the test server through the special bearing, and the test server evaluates the performance of the special bearing.
The test client downloads a target simulation service stream from a test server and sends the target simulation service stream to the test server through the special bearer; the test server receives the target simulation service flow sent by the test client through the special bearer; and the test server evaluates the service performance of the special bearer according to the target simulation service flow sent by the test client through the special bearer.
The test client initiates a test request to the test server, and the test server determines whether a dedicated bearer needs to be established according to the test request, and sends a dedicated bearer establishment request to the AF604 if the dedicated bearer needs to be established.
As shown in fig. 6, the Policy Control and Charging (PCC) mainly includes a policy and charging function (PCRF) 601, a Subscription Profile Repository (SPR) 603, a Policy and Charging Enforcement Function (PCEF) 602, and an application function AF 404. The PCRF601 is responsible for policy management, user management, subscription management and other functions, and provides network control policies or function indexes such as differential charging, gating, quality of service QoS guarantee and the like; the SPR603 is responsible for storing all subscribers or subscription-related information, including services allowed by the subscribers, priorities of the services, QoS information, and the like; the PCEF602 is responsible for policy enforcement and charging based on flows, and is generally superimposed in a GGSN/PGW network element, and can perform detection of service data flows in a combined manner; the AF604 is responsible for communicating with the PCRF601, interacting with dynamic sessions, and the like, and is typically deployed in the form of a service platform.
Further, as shown in fig. 7, the step of establishing the dedicated bearer is that the test server sends a dedicated bearer establishment request to the test server according to a service requirement, the test server determines whether the dedicated bearer needs to be established according to a rule set by the test server, when the condition for establishing the dedicated bearer is met, the test server sends the dedicated bearer establishment request to the AF, the AF triggers a QoS policy after receiving the dedicated bearer establishment request sent by the test server, the PCRF issues a policy to the PCEF according to the triggered QoS policy, and the PCEF executes the policy to establish the dedicated bearer for the application service flow for acceleration, so as to provide QoS guarantee. The result of the PCEF response strategy execution is fed back to the AF through the PCRF, and the result of whether the special bearing is successfully established or not is fed back to the test server side by the AF.
Specifically, whether the test client downloads the simulation service stream is determined according to the transmission direction of the real service stream in the test template, if the test client needs to send the simulation service stream to the test server, the test client downloads and uses the simulation service stream from the test server, otherwise, the test client does not need to download the simulation service stream from the test server. Optionally, the direction of the real traffic flow may be from the test server to the test client, or from the test client to the test server, or may be bidirectional simultaneous transmission (i.e. from the test server to the test client and from the test client to the test server).
As shown in fig. 8, the test client sends the downloaded target test template to the test server through the dedicated bearer, the test server determines the quality of the dedicated bearer service according to the value of the acquired parameter to be evaluated, the test server periodically generates a temporary test result, and after the test is finished, the whole test result is stored and sent to the test client.
