The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found in ETSI SR 000 314: “In

Latest updates are available on the ETSI Web server (http:/webapp.etsi.org/IPR/home.asp). Pursuant to the ETSI IPR Policy, no inv

No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This Technical Spec
27、ification (TS) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). This technical specification was previously published as a Technical Report. ETSI ETSI TS 183 025 V2.5.1 (2009-04)71 Scope The purpose of th
28、e present document is to define guidelines with regard to the interaction of non-call related H.248 procedures and generic network management use cases and vice versa. More specifically, the interaction between the following is considered: Control procedures at the H.248 interface. These are the pro
29、cedures between Media Gateway Controllers (primary and secondary) and their associated Media Gateways (primary, and secondary if available). These procedures primarily utilize the H.248 ServiceChange and H.248 Audit procedures. Management procedures at the management interface(s) of H.248 systems (i
30、.e. both Media Gateway Controller and Media Gateway) to perform non call related tasks such as configuration management (start-up, capability change, maintenance locking) and fault management (failure handling). It is intended that these guidelines are then subsequently used in corresponding H.248 p
31、rofiles to produce detailed non-call related procedures. At the current time, the existing set of ETSI H.248 profiles ( i.1, i.2, i.3 and i.4) lack any such detailed procedures. Specific management systems, architectures and protocols are outside the scope of the present document; only the general r
32、equirements and Use Cases related to the management system shall be discussed. 1.1 Applicability The present document is applicable to any network element that exhibits a H.248 interface and a management interface (e.g. SNMP). The intent of the present document is to provide guidelines so as to faci
33、litate a consistent set of behaviour for non-call related procedures in the related H.248 profile specifications. Due to the general nature of the present document, it is possible that some of the procedures herein will not be applicable to certain H.248 profiles - it is for a specific profile itsel
34、f to define which procedures are mandatory/optional/not applicable. The present document assumes an IP-based transport for H.248 signalling. The IP transport may be provided by either UDP or SCTP. 1.2 Relation to H.248 Standards The present document is considered to be complementary to H.248 standar
35、ds where there are discrepancies between the present document and the correspondent ITU-T Recommendation H.248 series Recommendations, the procedures of these ITU-T Recommendations (in particular ITU-T Recommendation H.248.1 i.5 and its annex F on ServiceChange), take precedence over those described

49、ntity NOTE 1: An H.248 entity relates to a Functional Entity (FE), any implementation of an H.248 entity is mapping the functional entity on a Physical Entity (PE). NOTE 2: E.g. a virtual MG (VMG) is a H.248 FE. Multiple VMGs are realized in a single physical MG, which relates to an H.248 PE. NOTE 3: Physical entities are sometimes also denoted as “platform“ or “processor“. primary Media Gateway (MG): no explicit definition in H.248 NOTE: The primary MG is rather implicitly defined.
