Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 shows a flowchart of a network element fault location method provided in an embodiment of the present invention. The network element fault positioning method is mainly used for processing network element faults of VoLTE Internet Protocol (IP) Multimedia Subsystem (IP Multimedia Subsystem, IMS) domains. As shown in fig. 1, the method for locating a network element fault includes:
step S11: and constructing a simulated public data network gateway and accessing the long-term evolution voice bearer network.
In the embodiment of the invention, the constructed simulated Public Data Network GateWay (PGW) can perform real service Data interaction with a voice over long term evolution (VoLTE) bearer Network, and the simulation has the capability of processing Non-access stratum (NAS) signaling of a VoLTE user.
As shown in fig. 2, the emulated public data network gateway simulates an SGI interface protocol on the PGW through a protocol emulation, and instead of a PGW entity with a complete function, the emulated public data network gateway does not carry existing network users on the emulated PGW, but only carries emulated terminals (UEs), that is, test numbers. Thus, when a simulated public data network gateway is constructed, a Non-access stratum (NAS) interface of the simulated public data network gateway is obtained; acquiring an emulation Gx interface between the emulated public data network gateway and the policy and charging rule function unit; acquiring a simulation S6a interface between the simulated public data network gateway and a policy and Home Subscriber Server (HSS); and acquiring a simulation SGi interface between the simulated public data network gateway and a policy and Proxy Session Border Controller (PSBC). The PSBC is an integrated network element integrating a Session Border Controller (SBC), a Proxy Call Session Control Function (P-CSCF), an Access Transfer Control Function (ATCF) entity, and an Access Transfer Gateway (ATGW).
The simulation public data network gateway realizes the simulation of the NAS layer protocol data of the VoLTE user through a simulation NAS interface, and realizes the functions of authentication and certification of the data. The simulated public data network gateway realizes data interaction with the existing network Policy and Charging control Function (PCRF) through a simulated Gx interface, and completes the default bearer China Mobile Internet (CMNET) creation and default bearer IMS bearer creation processes. As shown in fig. 3, the simulation Gx interface Protocol stack model can implement Protocol simulation on a Diameter Protocol, a Stream Control Transmission Protocol (SCTP), an IP Protocol, a physical layer (L1) Protocol, and a data link layer (L2) Protocol, and construct a Protocol simulation interface between a simulation PGW and a PCRF. The simulated public data network gateway realizes communication with the existing network HSS through a simulation S6a interface, completes a position updating process, and a protocol stack model of the simulated public data network gateway is shown in figure 4, can realize protocol simulation of a Diameter protocol, an SCTP protocol, an IP protocol, a physical layer (L1) protocol and a data link layer (L2) protocol, and constructs a protocol simulation interface between a Mobility Management Entity (MME) and the HSS. The MME is a part which is communicated with the HSS and has the same interface function with the mobile management entity in the simulation PGW. The simulated public data network gateway realizes that the simulated PGW is connected with the PSBC of the existing network through IP through the simulated SGi interface, and is matched with the NAS layer in a simulation way to simulate the VoLTE user, so that various VoLTE voice service test functions are realized. As shown in fig. 5, the SGi Protocol stack model of the simulation PGW can implement Protocol simulation on an IP Protocol, a GPRS tunneling Protocol-User (GTP-U), a User Datagram Protocol (UDP)/IP, a data link layer (L2), and a physical layer (L1) Protocol, and construct a Protocol simulation interface of the simulation PGW.
Taking a VoLTE registration process service test as an example, the working principle of the simulation PGW is shown in fig. 6, the simulation PGW performs simulation S6a interface location update through communication with an HSS, performs simulation Gx interface bearer CMNET creation and IMS creation through communication with a PCRF, and finally performs IMS registration through communication with a P-CSCF/SBC. Wherein, the LSP is a Low level signaling Transfer Point (Low Signal Transfer Point), the Diameter server is a Diameter protocol gateway program; i _ IES _ PS: is middleware that emulates a PGW; diameterStack is a Diameter protocol stack.
After the simulation PGW is constructed, the simulation PGW is accessed to a long-term evolution voice bearer network, and specifically, a logical link between the simulated public data network gateway and the agent session border controller in the long-term evolution voice bearer network is established through local data configuration. The simulation PGW is deployed in a provincial central machine room of an operator, a network cable between the simulation PGW and the current network equipment is laid, and an IP network between the simulation PGW and the opposite terminal PSBC is opened after a switch and a firewall are configured. The simulation PGW deployment adopts a centralized access and full-network coverage mode, and a logical link between the simulation PGW and the existing network PSBC is established through local data configuration. As shown in fig. 7, after the emulated PGW accesses the VoLTE IMS core network, when performing the IMS login test, the emulated PGW goes through the Session Border Controller (SBC) 1 to the Interrogating/serving call Session Control Function entity (I/S-CSCF), and completes the IMS login test. When the VoLTE voice call test is carried out, the simulation PGW is returned from the simulation PGW to the I/S-CSCF through the SBC1 and then through the SBC2, and a voice call is completed. The embodiment of the invention can facilitate subsequent planning of the specified test path by constructing the simulation PGE and directly specify all network elements.
Step S12: and determining the relation between any test number in the test data and the network element.
In the embodiment of the invention, in order to directly locate the fault of the network element in the VoLTE IMS domain through testing, the transparentization of the testing path needs to be realized firstly, namely the network element into which the testing data flow passes needs to be determined in advance, and the relationship between the testing number and the network elements such AS PSBC, I/S-CSCF (proxy/call session control function), application Server (AS) and the like is established. In step S12, a service call session control function entity and an application server are specified for any test number in a capability set manner.
As shown in fig. 8, a logical link is established between a group of PGWs virtualized by a simulation PGW and an existing network PSBC, so as to directly specify the existing network PSBC; and directly appointing the existing network S-CSCF and VoLTE voice AS by adopting a capability set mode. Applying for making capability set data of any test number on a home subscriber server to designate paths S-CSCF and AS; assigning a proxy session border controller through the emulated public data network gateway; randomly assigning, by the proxy Session border controller, the test number to a challenge call Session Control Function (I-CSCF); sending the test number to a designated serving call Session Control Function (S-CSCF) by the interrogating call Session Control Function according to the capability set data; and sending the test number to the appointed application server through the service call session control function entity according to the capability set data. In the whole process, the capability set data is made according to the contract signing data of the test number. The embodiment of the invention realizes the direct designation of S-CSCF and AS on the test path in the VoLTE IMS domain in a mode of capability set, and solves the problem that the network element can not designate and troubleshoot the fault after the current S-CSCF group Pool.
Step S13: and aiming at any test number, deploying a test task and a test path according to the relation between any test number and the network element and the network topology condition of the long-term evolution voice bearer network, and acquiring alarm information.
In the embodiment of the invention, the traversal monitoring and early warning of the VoLTE IMS core network fault are realized in a service test mode. Specifically, aiming at any one test number, a test task is deployed on a test interface, and an agent session boundary controller is configured; planning a test path by the configured agent session boundary controller according to the relation between any test number and a network element and the network topology condition of the long term evolution voice bearer network; and testing the test task according to the test number and the test path corresponding to the test number, and acquiring alarm information. As shown in fig. 9-11, a test number, an S6a interface, a Gx interface, and a P-SBC are configured on a test interface to complete the setting of a test task, specifically, a tester directly selects the test number, the S6a interface, the Gx interface, and the P-SBC. In addition, the PSBC IP is configured to realize the PSBC board level test of the existing network.
In the embodiment of the invention, the testing tasks of a signaling plane and a media plane are deployed according to the testing number and the testing path corresponding to the testing number and the long-term evolution voice bearer network full coverage principle, and a cycle test is carried out according to a preset testing granularity; and acquiring alarm information according to an alarm strategy configured for the test task. Referring to fig. 9, monitoring and early warning on a VoLTE signaling process of a VoLTE IMS domain service is realized by using a PGW VoLTE registration test, and a VoLTE signaling plane fault is actively discovered. For the media surface of VoLTE voice, fault early warning of Key Performance Indicators (KPIs) of the media surface of the VoLTE IMS domain is realized through a simulation PGW VoLTE bearer network test (see fig. 10) and a simulation PGW VoLTE voice call test (see fig. 11).
When test task deployment is carried out, voLTE signaling plane and media plane test tasks are deployed under all P-CSCF (PSBC) of the existing network, the test tasks are deployed according to the principle that the whole network elements and service routing paths of the VoLTE IMS domain are completely covered, and circular test is carried out according to the test granularity of 7 multiplied by 24 hours and 3 minutes/time. Each test task is configured with an alarm strategy, and a static alarm threshold of a test result can be set for each dial test index, for example: success rate is below 99.5%, response delay is below several milliseconds, etc. The dial testing indexes comprise registration success rate, response time delay, packet loss rate, single pass, silence and the like. At the initial stage of the dial testing index degradation, the active report of the alarm information is realized, and specifically, the alarm short message can be pushed to the maintenance personnel, so that the maintenance personnel can find and troubleshoot the problem in time.
Step S14: and positioning a fault network element according to the test path of the test task and the alarm information.
Specifically, the alarm information of at least three failed test tasks passing through different test paths is obtained; and positioning the network element at the intersection point of the test paths of at least three test tasks as the fault network element. In the embodiment of the invention, after at least three test tasks are deployed on the core network element of each VoLTE IMS domain, when the test tasks of different test paths under three different test numbers fail to alarm at the same time, the network element on the cross node of the test task can be directly positioned as a fault network element. For example, as shown in fig. 12, according to the capability set data of the test number, the test path of the test number 1 (test task 1) is: PSBC1- > I-CSCF1- > S-CSCF2- > AS1, and the test path of the test number 2 (test task 2) is: the test path of PSBC2- > I-CSCF2- > S-CSCF2- > AS3 and test number 3 (test task 1) is: PSBC3- > I-CSCF3- > S-CSCF2- > AS2, when all 3 test tasks fail, the S-CSCF2 of the network element through which the test task commonly passes is directly judged according to the task name (test number + path mode naming test task) or the network element IP address in the test detail list, so that the S-CSCF2 of the failed network element can be directly judged. The task name is the name of the test task named according to the test number + path mode.
The embodiment of the invention constructs a simulated public data network gateway and accesses a long-term evolution voice carrying network; determining the relation between any test number in the test data and the network element; aiming at any test number, deploying a test task and a test path according to the relation between any test number and a network element and the network topology condition of the long-term evolution voice bearer network, and acquiring alarm information; and positioning a fault network element according to the test path of the test task and the alarm information, so that the network element fault of the VoLTE IMS domain with hidden fault danger, active early warning and accurate positioning can be quickly found, the occurrence of missed alarm and error alarm is prevented, and the quality of the VoLTE network is improved.
