Mobile device
Dedicated telephone number
Voice Mail without Unified messaging
Location aware
Early attempts at FMC
• PBX control – trombone trunked
• SS7 gateways (Tango networks)
• Carrier provided
Cellular networks working
through the generations
• 1G – Analog Voice only
• 2G – GSM, CDMA, up to 20 Kbps Voice and
Data
• 2.5G CDMA2000, EDGE, GPRS up to 384
Kbps. Web browsing, MMDS, location services
• 3.0G CDMA 2000 and 3000, UMTS up to 3.1
Mbps. Full motion video, streamed video, 3D
gaming
4G networking
WiMax – Sprint Limited markets now
LTE – AT&Tand Verizon Wireless begin 2010
Bandwidth 100+ Mpbs
Applications - All of the above Plus:
High quality video streaming
High quality video conferencing
High quality Voice Over IP
4G is built upon IMS architecture
IP Multimedia Subsystem
• Developed by 3GPPP
• Uses SIP signaling
• FMC is based upon concept of Home and
Visiting networks
IMS Advantages
• Application Integration
• QoS
• Authentication sharing
IMS Architecture
IMS Nodes
• SIP Proxies
– S-CSCF – Network Controlling Proxy
– P-CSCF – Border SIP Proxy
– I-CSCF - Interrogating SIP Proxy
• Location nodes
– HSS Function of HLR and VLR
– SLF – Maps current IP address to
User/Application.
IMS nodes continued
• Gateway nodes
– BGCF – Border Gateway Control Function
– MGCF – Media Gateway Control Function
– MGW – Media Gateway
– SGW – Signaling Gateway
• Media Control
– MRFC – Media Control
– MRFP – Media Proxy
IMS nodes continued
• Application Servers (can either be home or
visiting network
– SIP AS
– OSA-CSC
– IM-SSF
Examples of Applications
• Carrier
– GPS Directions
– On line games
– Video on Demand
• University
– Blackboard access
– Emergency Notification
– Library and other controlled access systems
– VoIP over campus WiFi
Integration of Systems
• Campus Presence Server with HSS
• Campus VoIP Proxy with Wireless network
– One number dialing
– Integration of Voice Mail Systems
• Direct campus access to billing systems
• Negotiating QoS
Preparing your campus for IMS
• Consider DAS system (if appropriate)
• Student/Faculty discount programs with
carriers
• Understand the architecture and ready
applications for access
The future of Emergency
Communications
• FCC Initiatives
– CSRIC - Traffic Prioritization, CAP and other working
groups
– ERIC – Public private integration of 700 MhZ LTE
services
• ESI Net initiatives– It’s more than 911
– Campuses will connect
– It will probably be IPV6 only
