Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts.
Internet-Drafts are drafts documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet- Drafts as reference material or to cite them other than as "work in progress."


MEGACO package for Push To Talk over Cellular (PoC) Networks

Push To Talk over cellular (PoC) networks is supported through centralized Push To Talk Servers, which handles both SIP signaling, and the media (RTP) relay part. This document defines a distributed architecture for PoC Server implementation with PoC signaling server handling the SIP signaling and group management, whereas Media Server Handles the RTP relay part and the communication between these two servers is over MEGACO protocol using the package defined in this document.

M2UA Test Specifications document

This document presents the test specifications for M2UA (MTP2 User Adaptation) protocol (RFC 3331), which can be used to test M2UA implementations for conformance to the protocol definition. The list of test is exhaustive and covers almost all the categories of test. This draft can also be used in conjunction with M2UA specification by implementers of protocol as implementers guide, as the pictorial representation of various scenarios help easy understanding of the protocol. Next revision of the draft will cover the additions done to the protocol revision and any subsequent RFC published by IETF.

M3UA Conformance Test Plan

This document presents the test specification for M3UA (MTP3 User Adaptation) protocol (RFC 3332), which can be used to test M3UA implementations for conformance to the protocol definition. The list of test is exhaustive and covers almost all the categories of test. This draft can also be used in conjunction with M3UA specification by implementers of protocol as implementers guide, as the pictorial representation of various scenarios help easy understanding of the protocol.

SCTP Conformance Test Specification

This document presents the conformance test specification for SCTP prototcol (RFC2960), which can be used to test SCTP implementations for conformance to the protocol definition. The list of test is exhaustive and covers almost all the categories of test, except few test for timer calculation and congestion) which will be added in the next revision of the draft. This draft can also be used in conjunction with SCTP specification by implementor of protocol as implementors guide, as the pictorial representation of various scenarios help understand the protocol.

SUA Conformance Test Specifcation

The SUA is a protocol for the transport of any SS7 SCCP user Signaling (e.g. TCAP, RANAP or RNSAP messages) over IP. Between two signaling endpoints. This protocol can also support Transport of SCCP-user messages between two endpoints wholly contained within an IP network. Depending upon the upper layer Protocol supported, the SUA will need to support SCCP Connectionless service, SCCP connect-oriented service or Both services.

M3UA Congestion procedures

This Internet-Draft describes congestion procedures applicable for both M3UA [2] ASP and SG nodes. This draft explains all the procedures needed by M3UA [2] ASP and SG to handle local and network congestion communicated between M3UA [2] SG and ASP through SSNM messages. Congestion procedures proposed are in line with MTP3 Q.704 with some alteration to suit sigtran architecture.

Legal Intercept Package for Megaco/H.248

This document proposes a mechanism for MEGACO controlled legal intercept without the use of topology descriptor. Only call content duplication is addressed in this draft. The generation of call data information is outside the scope of this draft.

MEGACO Control Association State Machine

This draft is intended for people involved in designing and developing Media Gateways and Media Gateway Controllers. The document captures the description and interpretation of all the functional procedures and the related procedural parameters pertaining to the MG-MGC control association, as described in the MEGACO protocol.

It suggests the various states that the MG and MGC state machines go through during the life cycle of an association. It goes on to describe the various inputs each association state of an MG/MGC may deal with and how the MG/MGC may react towards them.

Requirement for Analysis of SIP Paths

This document is an Internet-Draft and is in full conformance with all provisions of Section 10 of RFC2026. This draft describes the requirements that need to be met for introducing a scheme that allows SIP based entities to record path related information.

This document is an Internet-Draft and is in full conformance with all provisions of Section 10 of RFC2026. Comments should be submitted to the appliances@research.telcordia.com mailing list.

This document proposes the use of SIP for network-capable appliances. It leverages the standard SIP capabilities to directly communicate with appliances even when they are behind firewalls, NATs or other entities that prevent direct end-to-end communication. When combined with a new method type and the SIP event extensions these techniques become even more powerful.

A variety of technologies are available to network appliances and provide home automation and control. However, these do not support wide-area access control and interworking of these Networked Appliances (NA). This document describes a new SIP method, DO, that allows a SIP UA to communicate with NAs.

Today, there are a variety of technologies available to network appliances and provide degrees of home automation and control. However, there is a lack of support for wide-area access control and interworking of these Networked Appliances (NA). The ability to provide such support will radically enhance people.

This document defines a R2 package in association with the MEGACO Protocol that can be used to control a Media Gateway (MG) from an external controller, called a Media Gateway controller (MGC).

The document describes the application of Resource Pool Control protocol, followed by requirements from this Protocol and then defines the Protocol Architecture with basic protocol definition. The annexure of the document gives few examples on RPCP usage.

This paper tries to explore the idea of modifying existing SS7 network protocol and network architecture to support packet voice services on it. It can also provide an easy transition path from circuit voice network to pure packet voice network
