Context-Based Services
Subscriber Context
CONTEXT DRIVES NEW SERVICES
Context can be determined at one time and reused by multiple applications. The innovative CBS platform makes it possible to develop a new class of wireless services. The platform extends the existing capabilities of location-based infrastructure to add subscriber contextual intelligence to the network. Context allows a mobile subscriber to specify how they want the outside world to communicate with them based on what they are doing, where they are, and when.
NEW SERVICE POSSIBILITIES
Driving-Related
Automatic map creation based on a mobile subscriber’s calendared event combined with their driving state. Notification to a parent that a teenager has either arrived at or departed from school. Traffic conditions or transit schedules for commuters.
Advertising
Subscriber opt-in to receive coupons or advertising from selected retailers. Location-based marketing apps – nearest retailer, current promotions, etc.
Geo-Social Networking
Presence and proximity of groups of friends, family, etc. Automatic updates to the subscriber’s selected social networking sites.
Productivity
Mediation of voice and text as a function of time of day, location, calendared events, etc. School zones to restrict a child’s use of the phone during school hours.
Mobile Entertainment
Games based on presence awareness. Sports information and entertainment.
WHAT IS CONTEXT?
Context is unique to each individual – what they are doing, where they are, and when. It is currently not known in any one network node.
For DriveAssist, four context states are used:
- Driving
- Stationary
- Emergency
- Passenger
The Aegis Control Server communicates the mobile device state to the wireless network for mediation. The types of services that can be developed using context are diverse. DriveAssist is just the start.
CBS DEVELOPMENT
At the onset of development, various technological solutions for providing DriveAssist were evaluated. Aegis Mobility’s Context-Based Services (CBS) platform was designed and developed to deliver DriveAssist via a client-server architecture that integrates with the wireless network.
This design allows for:
- A much thinner client (vs. a handset-only solution)
- Simple integration with diverse mobile devices
The platform also provides the wireless operator with a host of technological advantages including network efficiency and control over the voice, text, and data sessions for each mobile subscriber.
