Assignment Matrix
Assignment Matrix
Entry denote the cost of using a particular
device to serve the given media component.

• Computed using
• Cost Matrix (CC)
• Enabled Matrix (E)

Cost Matrix
Enabled Matrix
12
Cost Matrix
Cost Matrix

• Stores the cost associated with each media
  component and device pair
• Cost may depends on
• Users Preferences among devices
• Operational cost
• Other factors
• In general some relation of Preference ,
  Operational Cost etc

Preference Matrix
Operational cost matrix
13
Enabled Matrix

• Cell entries either 0 or 1
• Denotes which devices can be used to serve
  particular media component
• Depends on
• Capability of the device
• Location of the user
• Availability of the device

POSSIBLE USES

• Find-Me-Follow-Me
• Automatic Personal Assistant
• Filtering you Presence information for others.
• Slight Modifications can have interesting uses
• 3PCC
• Skill Based routing

15
SBR at a Call center

• Single Number, Multiple Operators
• Different Capabilities (e.g. Language)
• Administrative ratings
• Clients priority and operator clearance level
• data safety
• client protection

IMPLEMENTATIONS
17
Session Initiation Protocol

• Originally used to establish, modify and
  terminate multimedia sessions in the internet.
• Has evolved to be able to set-up a broad range of
  sessions
• Multimedia (e.g., voice, video, etc)
• Gaming
• Presence and Instant Messaging
• SIP provides the following functionality
• User location (not geographical location)
• User availability
• User capabilities
• Session set-up
• Session management

1. Find Me Follow Me

• With Group and Personal Preferences!!

23
Find Me Follow Me

• Several Users
• Can be contacted at different locations
• Users Move around
• Route call to the correct device as per users
  preferences and current location

24
Find Me Follow Me

• Several Options for users
• Change Location
• Individual preference per location
• Group preference per location

25

26
2. Multi Language Call Center
27
Multi Language Call Center

• One Number, Multiple Operators
• Each operator can put in his capabilities
• Administrator rates each operator on his/her
  speaking and writing skills
• Call routed to the highest rated operator who is
  capable of attending that call

3. Co-location
30
Co-location

• An interesting Application
• Users agree on sharing resources
• A simple implementation done to demonstrate
  concept

31
Co-location... a clever hack!!!
32
Future Work

• Large scale, web Based system
• Automatic Location gathering
• New fields of application, extensions
• Extend to mobile and PSTN

33
Conclusion and Discussion

• Feature rich, powerful framework
• Efficient algorithmic way to manage user
  preferences and Presence information
• Simple, easy to understand
• Can make use of existing technologies to do
  exciting stuff
• Full power still not realized
