Embodiment Construction

[0048] Some embodiments of methods, apparatus and computer programs may support low power implementations for context sensing. In some embodiments, it may be determined whether the user's device is "in motion" or "stationary" based on identification information (eg, cell id) and accelerometer information associated with an access point of the communication network. When a user is determined to be "in motion," the user may move from one location to another. In other words, the context may be "stationary" first, the context may be detected as "in motion" while the user is moving, and the context may return to "stationary" when the user has reached another place. Also, if the user is determined to be "stationary," it may be determined whether the user was in the same location before. A histogram of the user's environment and activity may be collected for the different "resting locations" visited by the user. After collecting some data for a "resting location", the histogram can...

Abstract

There is disclosed a method comprising receiving identifier data relating to a communication network; examining a set of identifier data to identify number of different identifier data in the set of location data; on the basis of the examining determining a status of an apparatus; and if the examining indicates that the status of the apparatus is a first state, examining context data relating to the first state to determine the current context of the apparatus. There is also disclosed a computer program comprising computer-executable program code portions stored therein, comprising program code instructions for performing the method. There is further disclosed an apparatus comprising a processor and a memory including computer program code, the memory and the computer program code configured to, with the processor, cause the apparatus to performing the method.

Description

technical field [0001] Various embodiments relate generally to electronic communication device technology, and more particularly, to a method and apparatus for context extraction. Background technique [0002] Current and future networking technologies continue to facilitate ease of information transfer and convenience to users by expanding the capabilities of mobile electronic devices. One area where the convenience of information transfer may be increased by demand relates to the delivery of services to users of mobile terminals. The service may be in the form of a specific media or communication application desired by the user, such as music player, game console, electronic book, short message, email, content sharing, web browsing, and the like. These services can also be in the form of interactive applications in which users can respond to network devices in order to perform tasks or achieve goals. Alternatively, the network device may respond to commands or requests m...
