Signaling Protocols and Architecture In
addition to the emerging physical network technologies being deployed,
RespondComm is looking into ways of leveraging emerging signaling
protocols and architectures to enhance public safety and emergency
communications.
As the cellular
networks continue to evolve and incorporate more multimedia content,
the signaling protocols have evolved to keep pace. Now that higher
bandwidth third generation (3G) networks are being deployed and
carriers are looking toward 4G networks, the core signaling protocol
that has gained a strong foothold is Session Initiation Protocol (SIP).
While SIP meets the needs of the cellular multimedia industry, it can
also provide a light-weight, robust signaling protocol for development
of enhanced public safety and emergency communications applications.
As
4G networks roll out over the next few years, the IP Multimedia
Subsystem (IMS) will be used as the architecture to enable rich
IP-based applications. The capabilities of IMS can be leveraged to
deliver enhanced applications for public safety and emergency response
as well.
Both SIP and IMS will be incorporated in the RespondComm applications development efforts.
