3GPP/IMS CompactSIP Source Code Protocol SIP Stack

SIP Overview

3GPP/IMS CompactSIP addresses the needs of manufacturers developing 3G handsets, 3G datacards, 3G mobile platforms and 3G chipsets by providing a 3GPP/IMS compliant software stack that supports the key 3GPP authentication and security standards plus the required IETF SIP RFCs. The 3GPP/IMS CompactSIP stack was jointly developed between TeleSoft International and the world's #1 mobile service provider in order to make available the smallest, most efficient SIP protocol software solution for the 3GPP/IMS market. 3GPP/IMS CompactSIP is tested to be standards compliant and network interoperable using in-house 3GPP/IMS handset emulators and network simulators plus private access to live 3GPP networks.

3GPP/IMS CompactSIP is ideal for all applications where compact memory space and fast code execution are important such as 3G SmartPhones, 3G Datacards, 3G Chipsets and 3G PDAs.

3GPP/IMS CompactSIP is also available pre-ported and tested with the Wind River TCP/IP networking stack.

Features

3GPP/IMS CompactSIP provides a small memory footprint, high performance SIP module:

3GPP/IMS CompactSIP is tight and fast:

• Support for methods, headers, and message processing is configurable to save memory.
• Smallest configuration fits in less than 100KB.
• Just-in-time parser avoids parsing headers not used by SIP stack or application.
• Optimized handling of timers avoids high start/stop overhead.
• Crafted parser eliminates typical parser-generator bloat.

3GPP/IMS CompactSIP is easy to use:

• Low-level API provides complete control over all SIP functions and message content.
• API supports multiple independent services including multi-homing.
• User can easily add special method and header processing.
• SDP parser is separate from SIP parser for use in other SDP applications.

3GPP/IMS CompactSIP is easily ported to any environment:

• Portable to any memory model, including flat, heap, pool-based, and mbuf or zbuf.
• Follows coding conventions used by other TeleSoft software stacks.
• Object-oriented API supports direct function-call interface, inter-task and inter-cpu messaging.
• Highly scalable – no built-in limits other than those required by the system itself.

3GPP/IMS CompactSIP provides a broad development and debugging environment:

• Sample applications to demonstrate use of the APIs.
• Initial ports include Linux, uCLinux, VxWorks, Nucleus, Windows and TsRITE OSes.
• Sample make files and imake scripts.
• Debugging & auditing features allow compile-time & run-time details for logging of messages & events.

Compliance Testing:

• Exclusive in-house 3GPP Handset emulator and Network Simulator test platforms.
• Private access to 3GPP networks allow extensive live testing.
• Rigorously tested against IETF RFC 4497 & PROTOS torture test suites and 3rd party equipment.
• Successful SIPit Interoperability testing against multiple vendors equipment.

Documentation:

• Comprehensive documentation.  Available in a searchable soft format.
