10. The Session Initiation Protocol Objective
Session Control Management interactive agent for Application Protocols
Service Connect Interaction Management
Improved Scope for Better Performance and Increased Message Flow
Advanced Protocol enabling Architectures of IMS,AIMS, GPS and AGPS
Perfect fit for Mission Critical Applications and fact finding operations
UAC and UAS could be first and second parties, third party will be a fork or a
database such as DNS Registrar or HSS(USDS)
Conference Control and Call Session Control Functionality will be handled by
proxy interrogating or serving CSCFs (LCP/LSM)
MGCP, MEGACO and SIP-I and SIP-T are complimentary protocols

11. The SIP for Context Awareness Objective
Bridging Applications across multi-platoform, multi-network leashing.
Service Connect Interaction Management for Context of time, location.
Improved Scope for Better Performance and Increased Message Flow.
A5350 AS/SCR is feature rich to serve context awareness requirements
Also A5020 AGCF for Gateway Control Function

12. SIP is a layered protocol and is made of 4 layers
• The lowest layer addresses the syntax and encoding
• The second layer is the transport layer; defines how requests and responses
are sent and received.
• The third layer is the transaction layer ; handles all the requests and the
responses for the same.
• The fourth layer is the transaction user layer.
• What MESSAGE, where IS UAC,UAS, how TO REACH, when TO SUBSCRIBE &
NOTIFY, how long DURATION, and with whom( USER PROFILE) or about whom
(USER PROFILE)

13. SIP- Because the world is always ON
High ratio of Mobile Internet
SIP active to adapt new technologies
and services
- 3G-UMTS, EV-DO, HSDPA,
WiMAX, WiFi and Blue tooth
- Camera Phone, Contact less IC Card,
- RF ID, GPS,
- Ring tone &
- Terrestrial Digital Broadcasting to be
extended to VoIP

15. The Representational State Transfer Objective
an approach for getting information content from a web site by reading a
designated Web page that contains an XML that has data (description as well
as content)
Can be useful for dynamically managed context aware data updation
Subscribers would only need to know the XML file that has delta and reform
data
REST uses RSS(RDF Site Summary). RSS uses the RDF (Resource Description
Framework) a standard way to describe a Web site or other internet resource
REST goes well with http and xml

17. Electron-Cardiogram Using SIP Registrar to Update a Communication Server/Service-ECP Data Provider
SIP
Step 1: User’s ECG is fed to a
Visualizer for expert Doctor at a
Remote End.
Step 2: The ECG Content Notifier Will
Alert SIP Registrar
Step 3:Based on the Database in SIP
Registrar, if there is a change, the
same will be flashed to CCN
Step 4:CCN in turn passes the Data to
ECG Data Provider
Step 5:Multiple SIP proxy Registrars
Could be involved in a case of Mobile
Environments/Location Changes

Mr. David
Your phone is aware of who is calling and it informs you custom message
regarding it
You have a call from your

20. Application Call Flow Example
1. User downloads file to AT
2. BM/PFO detects download start.
3. AM handles new and incoming call to user
Service
4. AM makes resource request to PM Broker 3

5. PM answers AM with an AB Mesg that
indicates that a file download is in
progress utilizing BW required for call 6
6. AM forwards session with AB Mesg to SB Application 4 Policy
for feature interaction processing Media Manager
Server Manager
7. SB interacts with User to determine (AM) (PM)

preference to download file and play
“canned” reply to calling party or delay 5

8. Based on User response, SB redirects
incoming call to media server and
instructs media server to plan Bearer 2
