Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of

19、 release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance,

20、i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction The Itf-N partitions two groups of interacting entities called IRPManager(s) and IRPAgent(s). The interactions between an IRPManag

21、er and IRPAgent are specified by the set of IRP specifications the IRPAgent supports, and which the IRPManager uses. Each YyyIRP (where “Yyy“ stands for Alarm, BasicCM, etc.) permits a manager to, via getIRPVersion, inspect its supported IRPVersion(s). Each such IRPVersion uniquely identifies one su

22、pported Interface IRP SS. Each YyyIRP may also permit an IRPManager to, via getNRMIRPVersions, inspect its supported NRM IRPVersion(s). Each such IRPVersion uniquely identifies one supported NRM IRP SS. The 3GPP IRP specifications are expected to evolve. For example, 3GPP Release 6 specifications in

23、clude more or modified features compared to the corresponding set in Release 5. An IRPManager and IRPAgent, with implementations conformant to the same IRP specification (at the same IRPVersion(s) will be able to communicate. However, an upgrade of the IRPVersion, if not performed by both IRPAgent a

24、nd IRPManager, can result in inter-working failure if Backward Compatibility (BC) issues are not addressed. The present document is applicable/relevant to a system context of a group of interacting IRPManagers and IRPAgents where some members are using one IRPVersion while others are using an upgrad

25、ed IRPVersion. ETSI ETSI TS 132 154 V13.0.0 (2016-02)53GPP TS 32.154 version 13.0.0 Release 131 Scope The present document gives recommendations to develop future IRP specifications in a Backward Compatible (BC) way so that the group of IRPManager(s) and IRPAgent(s) are not forced to be upgraded in

26、lock step. The business case for supporting such group, as described above, is complex. It may not relate to the functions of the supported IRPs alone. Rather, it can relate to the cost of coordination of IRPVersion upgrades, the cost of maintaining an old IRPVersion and the cost of using single-ven

27、dor or multi-vendor IRPAgents. These considerations are operator deployment scenarios specific. Clause 4 specifies the Recommendations and clause 5 describes the system context where the Recommendations are applicable. Editors Note: The forward compatability part is FFS. 2 References The following d

35、IRPVersion of the same kind, e.g. Alarm IRP. They also refer to NRM IRPVersion of the same kind, e.g. Core NRM. The new refers to a later release compared to the old. The words old and new, when qualifying an IRPManager, refer to an entity that is using the old or the new (Interface or NRM) IRPVersi

36、on. The words old and new, when qualifying an IRPAgent, refer to an entity that contains an IRP that is supporting the old or the new (Interface or NRM) IRPVersion. In majority cases, an IRPAgent instance contains multiple IRPs, each of which is using a particular Interface IRPVersion. In these case

37、s, each Recommendation statement should be repeated to cover all IRPs involved. The Recommendations do not imply that equipment vendors shall always supply their new IRPAgents in compliance to the solutions satisfying the Recommendations. The Recommendations simply identify the expected behaviours o

38、f a new system when it, claiming BC, interacts with an old system. Whether or not an IRPAgent should satisfy the Recommendations is a decision of the equipment vendor/supplier. The Recommendations do not imply that the next release of 3GPP Interface IRP or NRM IRP specification must be BC (to the ol

39、der one). Whether or not a new release of an Interface IRP or NRM IRP should be BC to its older version is a decision of the 3GPP specification author, on a case-by-case basis. ETSI ETSI TS 132 154 V13.0.0 (2016-02)73GPP TS 32.154 version 13.0.0 Release 134.2 Rules REC-1 An old IRPManager inter-oper

40、ates with an old IRPAgent-A and a new IRPAgent-B. The interaction shall be successful in that the IRPManager can obtain the network management services (capabilities and features) defined by the old IRPVersion from both IRPAgents. The IRPManager needs not have knowledge of new network management ser

41、vices defined by the new IRPVersion. REC-2 A new IRPManager inter-operates with a new IRPAgent-A and an old IRPAgent-B. The interaction shall be successful in that the IRPManager can obtain the network management services defined by (a) the new IRPVersion from IRPAgent-A and (b) the old IRPVersion f

42、rom IRPAgent-B. NOTE: If the next minor and/or major release of 3GPP Interface IRP or NRM IRP specification is BC (to the older one), one could reduce or eliminate the difficult coordination task to introduce IRPVersion upgrades in a large management domain containing multiple IRPManagers and IRPAge

43、nts. It can be more cost-effective if IRPVersion upgrades to individual entity (i.e. IRPManager and IRPAgent) are done at different times. ETSI ETSI TS 132 154 V13.0.0 (2016-02)83GPP TS 32.154 version 13.0.0 Release 135 BC context 5.1 General This clause defines the context under which the requireme

44、nts specified in the present document are applicable. The word old qualifies the related entity (i.e. the AlarmIRP of an IRPAgent instance or Alarm IRPManager) that is using an older 3GPP IRPVersion (called old version). The word new qualifies the related entity that is using a newer (upgraded) 3GPP

45、 IRPVersion. EXAMPLE: A hypothetical 3GPP TS 32.123 V6.0.0 is considered the old version with reference to 3GPP TS 32.123 V6.1.0. The two versions in question can belong to the same or different major releases (e.g. Rel-5 or Rel-6). The box labelled EM in figure 5.1 conveys the same idea as the box

46、of the same label in the System Context-A of other IRP specifications such as Alarm IRP IS 3GPP TS 32.111-2 3. One or all EM-labelled boxes of figure 5.1 can be interchanged with the NE-labelled box (see System Context-B of other IRP specifications such as Alarm IRP IS 3GPP TS 32.111-2 3). The NE en

47、tities are not shown in order to make the figure easier to read. NewIRPAgentItf-NEMOldIRPManagerNMNewIRPManagerNMOldIRPAgentEMFigure 5.1: Overall BC System Context In general, an IRPAgent instance may contain several Interface YyyIRP instances and associated supporting Yyy NRM IRPs (where one IRP ca

48、n be for example Alarm IRP, Test Management IRP, or “Notification IRP“, etc and where the other IRP can be for example Generic IRP). The Interface and NRM YyyIRP specifications of particular IRPVersion(s) together specify the behaviour of an Interface IRP and the supporting NRM IRP (s). NOTE: The IR

49、PVersion concept is related to the IRP. The IRPVersion concept is not related to the IRPAgent as this may contain multiple IRPs. Given this background, the BC issues are addressed at two separate but related levels as described in clauses 5.2 and 5.3.
