Section 2 presents a generic IPTV architecture, while section 3 describes standardization efforts such as TISPAN
, OIPF, ITU-T and ATIS specifications for the next generation IPTV.
Spectra2's legacy of success with PSTN and VoIP networks provides a solid foundation for extending the solution to provide test coverage in next-generation IMS and TISPAN
networks," said Richard Kenedi, General Manager of Function and Load Diagnostics, Tektronix Communications.
The Alcatel-Lucent 5750 SSC also allows Brazoria Telephone to evolve its network to include innovative IP multimedia subsystem (IMS) service and TISPAN
(Telecoms & Internet converged Services & Protocols for Advanced Networks) functions that reduce the cost of introducing IMS applications.
This strategy is supported by a strong commitment to new network architectures such as IMS (IP Multimedia Subsystem) and TISPAN
(Telecoms & Internet converged Services & Protocols for Advanced Networks).
Because of its flexibility, security and reliability, Diameter is the AAA protocol mandated for use by many IMS and TISPAN
interface specifications, including several of those supported on Acme Packet's family of SBCs, multiservice security gateways (MSGs) and session routing proxies (SRPs).
New network architectures such as IMS (IP Multimedia Subsystem) and TISPAN
(Telecoms & Internet converged Services & Protocols for Advanced Networks) specify an elaborate network access layer for solving these issues, opening up a new market for network access control devices.
The G2 is compatible with IMS, TISPAN
NGN, MSF, and PacketCable networks, and interoperable with the world's leading softswitches, circuit switches, SIP application servers, GENBAND border gateways, IP and TDM access equipment, and CPE.
The RADVISION IMS Express is compliant with the latest IMS 3GPP, TISPAN
, and Packet Cable 2.
Standards bodies that drive IMS: including ITU, IMT-2000, 3GPP/3GPP2, R5/R6, IETF, CableLabs, ETSI, TISPAN
, ATIS, SIPPINGS, OMA -- Fundamentals of SIP: Elements and session flow, message format -- IMS Basics: IMS network groundwork, examples of IMS call flows -- SIP Clients for IMS: SIP extensions, security, signaling compression, ENUM, NAT traversal, IPv6 support
In part 1, more information on TISPAN
, I-WLAN, Cable is included and chapters are added on subjects such as 'IMS transit', 'Communication Continuity (VCC / PS-2-PS Handover)' and 'IMS interconnection'.
Introduces the reader to the current cellular telephony architecture and to voice over IP architectures such as SIP, IMS and TISPAN
Information about the role of Acme Packet's session border controllers in IMS architectures, including 3GPP, ETSI TISPAN
, Multiservice Switching Forum and PacketCable, is available on Acme Packet's website.
