Introduction The present document is part of a TS-family covering the 3rdGeneration Partnership Project: Technical Specification Group Services
22、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 Point (IRP): Information Service (IS)“. 32.366: “Entry Point (EP) Integration Reference Point (IRP); Solu
23、tion 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 TS 32.101 1. The TM architecture is described in 3GPP TS 32.102 2. The other specifications define the i
24、nterface (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 composed of a number of Integration Reference Points (IRPs) defining the information in
25、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 IRPs with special function. It is difficult for an NM to discover all IRPs in the environment where ther
26、e 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 and their related IRPs.

32、 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 (provided by that IRP). The implementation of IRP Reference is technology dependent. For example, i
33、n 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 supports more than one IRP versions, there is a mechanism for NM to select the needed IRP version, an

36、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 32.111-1 3, etc.) are defined for specific management domains and are all published. 3GPP specificatio
37、ns 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 different network management domains services exist. Multiple IRPs providing the same network management
38、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 for an NM to discover all of them. The matter is further complicated in a multi-vendor environmen
39、t 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 eliminate the NMs difficulties mentioned above. The Entry Point is the name of such management serv
40、ice. 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 network resources that it is responsible for) in the managed systems. 2) It supports NM to obtain th
41、e 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 system the References it will not use again. Whether the managed system should release them or not is
42、 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 latest IRPAgent deregister information or their scope of management stored in EPIRP at run time.
43、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 Figure 1. Using the provided Reference, say the Reference to PMIRP, the IRPManager invokes operations
44、 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. Each IRPAgent can contain one or more IRPs. An EPIRP is contained by an IRPAgent. This containing
45、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 as SubNetwork, is defined by the Generic NRM IRP in 3GPP TS 32.622 5. This containment relation
46、has no relation to the EPIRP knowledge regarding IRP ETSI ETSI TS 132 361 V15.0.0 (2018-07)73GPP TS 32.361 version 15.0.0 Release 15References. 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 instanc
47、e 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 SubNetwork instances. This is the choice of the vendor producing such product. See annex A for exampl
48、e 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 References in one EPIRP. Each vendor should minimize the number of EPIRPs for the support of all their IR
49、P References. How EPIRP is made aware of IRP References are outside the scope of standardization. NOTE: The * depicts the IRP Reference returned by EPIRP. See Reference definition.
