Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN); H.248 Non-Call Related Procedures and Management System Interaction (V2.2.0)
The purpose of the 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 procedures between Media GatewayControllers (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.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 profiles to produce detailed noncall 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 requirements and Use Cases related to the management system shall be discussed. 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 facilitate 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 itself to define which procedures are mandatory/optional ot applicable. The present document assumes an IP-based transport for H.248 signalling. The IP transport may be provided by either UDP or SCTP. Relation to H.248 Standards The present document is considered to be complementary to H.248 standards 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 in the present document.
