Introduction The present document is part 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): Requirement
21、s“. 32.362: “Entry Point (EP) Integration Reference 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
22、 3G systems. The TM principles are described in 3GPP TS 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 e
23、ither an Element Manager (EM) or the managed NE itself. 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
24、from the agent to the manager. EPIRP is one of these IRPs 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 conve
25、nient mechanism for NM to discover the managed systems and their related IRPs. ETSI ETSI TS 132 361 V14.0.0 (2017-04)53GPP TS 32.361 version 14.0.0 Release 141 Scope The present document describes the requirements of the EPIRP. 2 References The following documents contain provisions which, through r
26、eference in this text, constitute provisions of the present 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
27、version applies. In the case of a reference to a 3GPP document (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 require
28、ments“. 2 3GPP TS 32.102: “Telecommunication management; Architecture“. 3 3GPP TS 32.111-1: “Telecommunication management; Fault management; Part 1: 3G fault management requirements“. 4 3GPP TS 32.601: “ Telecommunication management; Configuration Management (CM); Basic CM Integration Reference Poin
29、t (IRP): Requirements“. 5 3GPP TS 32.622: “Telecommunication management; Configuration Management (CM); Generic network resources Integration Reference Point (IRP): Network Resource Model (NRM)“. 3 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the following
30、terms and definitions apply: Entry Point (EP): access point 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 or
31、der to request and obtain the network management services (provided 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
32、 IRPAgent. Version negotiation: when the managed system supports 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 V14.0.0 (2017-04)63GPP TS 32.361 version 14.0.0 Release 143.2 Abbrevia
33、tions For the purposes of the present document, the following abbreviations apply: CM Configuration Management CORBA Common Object Request Broker Architecture DN Distinguished Name EP Entry PointEPIRP Entry Point IRP EM Element ManagerEP Entry Point IOC Information Object Class IOR (CORBA) Interoper
34、able Object Reference IRP Integration Reference Point NE Network 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
35、32.601 4, the fault management requirements in 3GPP TS 32.111-1 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 m
36、atter. In a large network, multiple IRPs, providing different 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 Alarm
37、IRP manages the western region). Its difficult and fallible 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 t
38、he NM to discover the References, in a standard way would eliminate 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 IR
39、PVersions and their scope of management (e.g. the set of network 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
40、needs. Entry Point allows NM to indicate to the managed system 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 P
41、oint contents, e.g. latest IRPAgent register information or 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
42、, is shown as the arrow from EPIRP to IRPManager in the Figure 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 relatio
43、ns with IRPs. There can be a single or multiple IRPAgents. Each 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 IR
44、PAgent containment relation, with respect to other IOCs such 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 V14.0.0 (2017-04)73GPP TS 32.361 version 14.0.0 Release 14References.
45、 To say it in another way, the EPIRP knowledge about IRP References 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 c
46、an have knowledge of IRP References of IRPs under other SubNetwork 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 impl
47、emented by that vendor, but not necessarily all IRP References 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. NOTE: The * depicts the IRP Reference returne
48、d by EPIRP. See Reference definition.

49、 Before IRPManager can interact with an IRP to obtain network management services, say AlarmIRP, it must know the IRPs Reference. Without the EPIRP, the IRPManager shall get information about these IRP References in a vendor-specific way. 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 m
