Introduction The present document is part of a TS-family covering the 3rd Generation Partnership Project; Technical Specification Grou
21、p Services and System Aspects; Telecommunication management; as identified below: 32.321: “Test management Integration Reference Point (IRP): Requirements“; 32.322: “Test management Integration Reference Point (IRP): Information Service (IS)“; 32.326: “Test management Integration Reference Point (IR
22、P): Solution Set (SS) definitions“. A 3G telecommunication network is composed of a multitude of different network elements (NE). For a successful operation of the network the operator must be provided with mechanisms allowing him to manage the network. These management activities can be grouped int
23、o several areas: configuration management, fault management, performance management, accounting management and security management. A management function assisting in different high level management areas such as fault management and performance management is test management. The purpose of testing
24、is to get information about the functionality and performance of the 3G managed network subject to the test. The present document is part of a set of technical specifications defining the telecommunication management (TM) of 3G systems. The TM principles are described in 3GPP TS 32.101 5. The TM arc
25、hitecture is described in 3GPP TS 32.102 6. The other specifications define the interface (ITf-N) between the managing system (manager), which is in general the network manager (NM) and the managed system (agent), which is either an element manager (EM) or the managed NE itself. The Itf-N is compose
26、d of a number of integration reference points (IRPs) defining the information in the agent that is visible for the manager, the operations that the manager may perform on this information and the notifications that are sent from the agent to the manager. One of these IRPs is the Test Management IRP.
27、 Each IRP is specified by a set of TSs: Requirements, Information Service, CORBA SS, etc. ETSI ETSI TS 132 321 V14.0.0 (2017-04)53GPP TS 32.321 version 14.0.0 Release 141 Scope The present document describes, in addition to the requirements defined in 1 and 2, the requirements for the Test Managemen

34、ose of monitoring and controlling a test invocation Each test invocation has one associated TO. TOs are created and deleted by managed objects with TARR functionality. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: NE Network Element NM Network Managem
35、ent Center TARR Test Action Request Receiver TO Tester Object 4 Purpose The purpose of testing is to get information about the functionality and performance of the 3G managed network subject to the test. This information can be used in other network management areas, for instance in fault management
36、 Testing is an activity that involves the operator, the managing system (the OS) and the managed system (the NE). Generally the operator requests the execution of tests from the OS and the managed NE autonomously executes the tests without any further support from the operator. In case of intrusive
37、 tests it is required that the network resources to be tested are locked prior to test execution. During the test execution the telecommunication service provided by the network resources is interrupted. After completion of the test, depending on the test result, the network resources shall be set t
38、o the most appropriate state. Test management capabilities should be provided over the Itf-N in order to allow the NM operator to perform tests on network resources. This capability is especially important at times when only the NM but not the OMC is attended, which might be the case at night or dur
39、ing weekends. In the context of fault management the NM operator may use the testing capabilities over the Itf-N for numerous purposes: - When a fault has been detected and if the information provided in the alarm report is not sufficient to localise the faulty resource, tests can be executed in ord
40、er to localise the fault. - When a fault has been detected and if the information provided in the alarm report specifies the faulty resource, tests can be executed on that resource in order to determine the required repair action. - During normal operation of the NE, tests can be executed for the pu
41、rpose of discovering undetected faults. - After a faulty resource has been repaired or replaced and before it is restored to service, tests can be executed on that resource in order to make sure that it is fault free. However, regardless of the context where the testing is used, its target is always
42、 the same: verify if a systems physical or functional resource performs properly and, in case it happens to be faulty, provide all the information to help the operator to localise and correct the fault. The requirements for the test management service shall be based on ITU-T Recommendation X.745 3.
43、ETSI ETSI TS 132 321 V14.0.0 (2017-04)73GPP TS 32.321 version 14.0.0 Release 145 Requirements 5.1 Overview The IRPManager (test conductor) must be able to initiate and terminate tests. For this purpose special test initiation and termination requests may be used. The IRPAgent (test performer) must b
44、e able to receive and react upon these requests. Special objects may be created for the purpose of monitoring and control of the test execution. During test execution the IRPManager shall be able to monitor the test. Test results shall be made available to the IRPManager by test result reports (noti
45、fications). It shall be possible to log these test result reports. This gives rise to the following requirements for the test management function to be satisfied: - the ability for the manager to initiate tests; - the ability for the manager to terminate tests; - the ability for the manager to monit
46、or the test execution; - the specification of a mechanism to report the test results to the manager; - the specification of a mechanism to log test results in the agent. These capabilities are outlined in the following sections in more detail. 5.2 Test 5.2.1 Test Initiation The IRPManager shall be a
47、ble to initiate a test in the IRPAgent by sending a test request to the IRPAgent. The IRPAgent must have at least one object instance capable of receiving these test requests. In response to a test request one or more tests shall be initiated. Each test shall be controlled and monitored individually
48、 by special objects instantiated exclusively for this purpose. These objects are called Tester Objects (TOs). Each of the tests initiated in response to a test request shall have a single associated TO. The test request shall include the following information: - The network resources to be tested. -
49、 Information about the managed objects (e.g. TOs) assisting in the test execution. - Any other information useful for the test execution. In response to the test request the IRPAgent shall send a test request response to the IRPManager. For a successful test request this response shall contain the following information: - A unique identifier for each test initiated by the test request. - Information about the managed objects assisting to execute the test. For a failed test request the response shall contain the following information: - Informati
