2.1 Please describe the proposed Specification:This JSR aims to elaborate a JAINTM API that leverages the Session Initiation Protocol (SIP) to provide instant messaging. The Session Initiation Protocol (SIP) is an IETF standard signaling protocol that can be used to establish, modify and terminate sessions in IP networks. SIMPLE is an IETF working group that advanced a set of extensions to SIP to support presence and instant messaging. This JSR aims to create a JAINTM specification to the SIP extensions for instant messaging. 2.2 What is the target Java platform? (i.e., desktop, server, personal, embedded, card, etc.)The target platform for JAINTM SIMPLE Instant Messaging is the JavaTM 2 micro and standard editions. The micro edition is meant to be the platform for client devices (primarily handsets). The standard edition is meant to be the platform for desktop-based clients.
2.3 What need of the Java community will be addressed by the proposed specification?The proposed specification will spur the development of JAINTM-compliant combined services and applications (web, mail, chat, messaging, presence, etc.) that leverage the flexibility of SIMPLE. It will provide Java developers with a standard API to SIMPLE protocol stack providers and allow them to use a multitude of SIP and SIMPLE-enabled applications. As for carriers, it will remove their dependence on a specific SIP/SIMPLE vendor and allow them to integrate with other JAINTM solutions. 2.4 Why isn't this need met by existing specifications?There are no existing Java specifications of an API that support instant messaging on top of the SIP protocol. It is well established that SIP offers tremendous advantages with the SIMPLE extensions to support presence and instant messaging: unification of major communication services, sharing of databases, sharing of proxies, sharing of servers, reduction of management costs, enabling of new combined services, etc. Moreover, JAINTM SIMPLE Instant Messaging comes as a natural extension to the JAINTM SIP and JAINTM SIP Lite APIs. As JAINTM SIP is a standard API to the SIP protocol, and JAINTM SIP Lite is a lightweight definition of SIP for user agents (including J2ME devices), in a similar vein, the JAINTM SIMPLE Instant Messaging API is intended to be a standard API to the SIMPLE protocol (i.e. SIP augmented with instant messaging capabilities for server and client devices). 2.5 Please give a short description of the underlying technology or technologies:? ? SIP is an IETF standard protocol for IP-communication, enabling IP-telephony gateways, client endpoints, PBXs and other communication systems or devices to communicate with each other. SIP primarily addresses the call setup and tear down mechanisms of sessions and is independent of the transmission of media streams between caller and callee. ? SIMPLE is a set of extensions made to the SIP protocol to support presence and instant messaging. ? JAINTM SIP API fully supports the SIP protocol, and is dedicated to Java session control in the telecommunications and Internet industry. ? JAINTM SIP Lite is an abstract JAINTM API to the SIP protocol that is dedicated to user agents running on both the J2SE and J2ME platforms. 2.6 Is there a proposed package name for the API Specification? (i.e., javapi.something, org.something, etc.)The package names being considered are: ? javax.jain.ip.simple.security: This package contains security mechanisms that enforce the authorization property. It is primarily to support access control lists. ? javax.jain.ip.simple.im: This package contains instant messaging capabilities (sending messages, receiving messages, opening and closing messaging sessions, resuming messaging sessions, etc.). 2.7 Does the proposed specification have any dependencies on specific operating systems, CPUs, or I/O devices that you know of?No 2.8 Are there any security issues that cannot be addressed by the current security model?The proposed API needs to enforce the following security properties: authentication, secrecy and authorization. Authentication and secrecy are fully addressed by the JavaTM security model. However, the API must implement a mechanism to enforce authorization. In particular, an ACL (Access Control Lists) model to manage authorizations for subscription requests at the level of the presence servers is required. 2.9 Are there any internationalization or localization issues?The expert group developing this specification will research the internationalization and localization requirements. 2.10 Are there any existing specifications that might be rendered obsolete, deprecated, or in need of revision as a result of this work?No 2.11 Please describe the anticipated schedule for the development of this specification.The anticipated schedule is:
? Requirements: T0 + 4 weeks. where T0 is the time at which the expert group starts working on the elaboration of this proposal. 2.12 Please describe the anticipated working model for the Expert Group working on developing this specification.The anticipated working model will use:
? A dedicated mailing list. Section 3: Contributions
3.1 Please list any existing documents, specifications, or implementations that describe the technology. Please include links to the documents if they are publicly available.? ? Panasonic JAINTM-SIMPLE API is being elaborated as a joint research and development initiative between Columbia University (Dr. Henning Schulzrinne) and Panasonic Information and Networking Technologies Laboratory (Dr. Alexander Gelman and Dr. Mourad Debbabi). ? Panasonic JAINTM SIP Lite implementation has been architected, designed and implemented by Panasonic Information and Networking Technologies Laboratory. ? Panasonic Information and Networking Technologies Laboratory and Laval University in Canada are working on a joint research and development initiative that aims to accelerate and secure the J2ME/CLDC platform. ?

3.2 Explanation of how these items might be used as a starting point for the work.Our strong starting point in this initiative is twofold:
? A well-defined protocol produced by the IETF SIMPLE working group. This definition comes as a set of extensions to the SIP signaling protocol to support presence and instant messaging. Moreover, we plan to leverage our expertise in SIP, JAINTM SIP, JAINTM SIP Lite and J2ME to elaborate the proposed API. Section 4: Additional Information (Optional)
