20、art of a TS-family covering the 3rdGeneration Partnership Project: Technical Specification Group Services and System Aspects; Telecommunication management, as identified below: 32.361: “Entry Point (EP) Integration Reference Point (IRP): Requirements“ 32.362: “Entry Point (EP) Integration Reference
21、Point (IRP): Information Service (IS)“ 32.366: “Entry Point (EP) Integration Reference Point (IRP); Solution Set (SS) definitions“ 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 T
22、S 32.101 1. The TM architecture is described in 3GPP TS 32.102 2. 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
23、. The Itf-N is composed 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. EPIRP is one of these I
24、RPs with special function. It is difficult for an NM to discover all IRPs in the environment where there are several managed systems and/or if there are multiple IRPs related to each managed system. This Entry Point is proposed to provide a convenient mechanism for NM to discover the managed systems
25、 and their related IRPs. ETSI ETSI TS 132 361 V13.0.0 (2016-02)53GPP TS 32.361 version 13.0.0 Release 131 Scope The present document describes the requirements of the EPIRP. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the pr
26、esent document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP docume
27、nt (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TS 32.101: “Telecommunication management; Principles and high level requirements“. 2 3GPP TS 32.102: “Telecommunication management; Arc

30、between NM and the managed systems and provides the way for NM to discover the References of IRPs in the managed systems Reference: defines the IRP network management service access point. The IRPManagers connect to this IRP Reference in order to request and obtain the network management services (p
31、rovided by that IRP). The implementation of IRP Reference is technology dependent. For example, in CMIP, this is the address of the CMIP IRPAgent and application context of the CMIP IRP. In CORBA, this is the IOR of the IRP contained by the IRPAgent. Version negotiation: when the managed system supp
32、orts more than one IRP versions, there is a mechanism for NM to select the needed IRP version, and invoke the most appropriate management operations ETSI ETSI TS 132 361 V13.0.0 (2016-02)63GPP TS 32.361 version 13.0.0 Release 133.2 Abbreviations For the purposes of the present document, the followin

34、work Element NM Network ManagerNRM Network Resource Model PM Performance Management4 Entry Point concept and requirements In the 3GPP Release 5 specifications and earlier Releases, the IRPs (such as the Basic CM IRP Requirements in 3GPP TS 32.601 4, the fault management requirements in 3GPP TS 32.11
35、1-1 3, etc.) are defined for specific management domains and are all published. 3GPP specifications do not provide standard mechanism for NM to discover the References of the IRPs in the managed systems. The discovery is a vendor-specific matter. In a large network, multiple IRPs, providing differen
36、t network management domains services exist. Multiple IRPs providing the same network management services (e.g. fault management) but of different management scope may exist (e.g. one AlarmIRP managing the eastern region while another AlarmIRP manages the western region). Its difficult and fallible
37、for an NM to discover all of them. The matter is further complicated in a multi-vendor environment where each vendor provides different way for NM to discover the References of its IRPAgent and related IRPs. A management service, allowing the NM to discover the References, in a standard way would el
38、iminate the NMs difficulties mentioned above. The Entry Point is the name of such management service. Entry Point provides the following: 1. It allows NM to discover outline information of IRPs, including the DN of IRPs and the supported IRPVersions and their scope of management (e.g. the set of net
39、work resources that it is responsible for) in the managed systems. 2. It supports NM to obtain the References of the IRPs of specific IRPVersion by means of the IRPManager inputting the DN of the IRP which supports the IRPVersion number it needs. Entry Point allows NM to indicate to the managed syst
40、em the References it will not use again. Whether the managed system should release them or not is outside the scope of this specification. A notification shall be supported for keeping IRPManager timely informed about the changes of Entry Point contents, e.g. latest IRPAgent register information or
41、latest IRPAgent deregister information or their scope of management stored in EPIRP at run time. The EPIRP provides the References of various IRPs to the IRPManager at run time. That interaction, to be standardised by this IRP specification, is shown as the arrow from EPIRP to IRPManager in the Figu
42、re 1. Using the provided Reference, say the Reference to PMIRP, the IRPManager invokes operations to access the PM domain specific management services. The context diagram figure 1 does not show the IRPAgent(s) and their containment relations with IRPs. There can be a single or multiple IRPAgents. E
43、ach IRPAgent can contain one or more IRPs. An EPIRP is contained by an IRPAgent. This containing IRPAgent may or may not contain other instances of other IRPs such as AlarmIRP. This is the choice of the vendor producing such product. The IRPAgent containment relation, with respect to other IOCs such
44、 as SubNetwork, is defined by the Generic NRM IRP in 3GPP TS 32.622 5. This containment relation has no relation to the EPIRP knowledge regarding IRP ETSI ETSI TS 132 361 V13.0.0 (2016-02)73GPP TS 32.361 version 13.0.0 Release 13References. To say it in another way, the EPIRP knowledge about IRP Ref
45、erences has no relationship to its Distinguished Name. An EPIRP, named under one IRPAgent instance can have knowledge of IRP References of IRPs named under other IRPAgent instances. An EPIRP, named under one particular SubNetwork instance can have knowledge of IRP References of IRPs under other SubN
46、etwork instances. This is the choice of the vendor producing such product. See annex A for example figures to show EPIRP knowledge. All the IRP References provided by one vendors product should be found in at least in one of the EPIRPs implemented by that vendor, but not necessarily all IRP Referenc
47、es in one EPIRP. Each vendor should minimize the number of EPIRPs for the support of all their IRP References. How EPIRP is made aware of IRP References are outside the scope of standardization.

With the EPIRP, the IRPManager can discover these IRP References using the EPIRP defined protocol. Before the IRPManager can interact with the EPIRP, it must know the EPIRP Reference. How the IRPManager acquire this knowledge is outside the scope of this specification. 5.1.2 Version negotiation The version of IRPs may be updated for some appropriate reasons. Version ne
