Abstract

A server based contextual awareness method of communicating in a wireless network includes detecting a signal strength of one or more user equipments (UEs) relative to other user equipment within a same vicinity. The method also includes detecting a pattern of the user equipment(s) and the other user equipment based on the detected signal strength of the user equipment(s) relative to the other user equipment. The method also includes deriving a social context based on the detected pattern. The method further includes initiating an action in response to the derived social context.

Claims

1. A contextual awareness method comprising:

accessing, using a receiver coupled to an antenna, signal strength information of signals received by at least one user equipment from other user equipment within a same vicinity, wherein the at least one user equipment is a mobile device;

determining a location of the at least one user equipment relative to at least two other user equipment based on the signal strength information;

determining a user equipment pattern of the at least one user equipment and the at least two other user equipment based on the determined location of the at least one user equipment relative to the at least two other user equipment;

deriving a social context based on the determined user equipment pattern by comparing the determined user equipment pattern with predetermined patterns associated with different social contexts; and

initiating an action of the at least one user equipment in response to the derived social context.

2. The method of claim 1, further comprising:

dynamically tracking changes in the user equipment pattern; and

deriving the social context based on the tracked changes in the user equipment pattern.

3. The method of claim 1, in which deriving the social context comprises one of determining a driver of a vehicle, determining a speaker of a meeting, and determining a teacher in a classroom.

4. The method of claim 1, in which accessing signal strength information comprises accessing information indicative of signal strength for at least one signal type selected from the group consisting of Bluetooth signal, a Wireless Local Area Network (WLAN) signal, and an ultrasound signal.

5. The method of claim 1, in which initiating the action further comprises one of:

initiating a process to switch the at least one user equipment to a vibrate mode,

initiating transfer of control of a shared application,

computing a length of a queue and determining information about an average wait time of the queue,

initiating launch of an application on the at least one user equipment, and

routing incoming text messages to passengers of a vehicle.

6. An apparatus comprising:

a memory; and

at least one processor coupled to the memory and configured;

to access, using a receiver coupled to an antenna, signal strength information of signals received by at least one user equipment from other user equipment within a same vicinity, wherein the at least one user equipment is a mobile device,

to determine a location of the at least one user equipment relative to at least two other user equipment based on the signal strength information,

to determine a user equipment pattern of the at least one user equipment and the at least two other user equipment based on the determined location of the at least one user equipment relative to the at least two other user equipment,

to derive a social context based on the determined user equipment pattern by comparing the determined user equipment pattern with predetermined patterns associated with different social contexts, and

to initiate an activity of the at least one user equipment in response to the derived social context.

7. The apparatus of claim 6, in which the at least one processor is further configured:

to dynamically track changes in the detected user equipment pattern; and

to derive the social context based on the tracked changes in the user equipment pattern.

8. The apparatus of claim 6, in which the at least one processor is further configured to derive the social context by one of:

determining a driver of a vehicle, determining a speaker of a meeting, and determining a teacher in a classroom.

9. The apparatus of claim 6, in which the accessing the signal strength information comprises accessing information indicative of one or more signal strength types selected from the group consisting of:

Bluetooth signal strength, Wireless Local Area Network (WLAN) signal strength, and ultrasound signal strength.

10. The apparatus of claim 6, in which the at least one processor is further configured to initiate the activity by one of:

initiating a process to switch the at least one user equipment to a vibrate mode,

initiating transfer of control of a shared application,

computing a length of a queue and determining information about an average wait time of the queue,

initiating launch of an application on the at least one user equipment, and

routing incoming text messages to passengers of a vehicle.

11. A computer program product for wireless communications in a wireless network, comprising:

a non-transitory computer-readable storage medium having program code recorded thereon, the program code comprising;

program code to access, using a receiver coupled to an antenna, signal strength information of signals received by at least one user equipment from other user equipment within a same vicinity, wherein the at least one user equipment is a mobile device,

program code to determine a location of the at least one user equipment relative to at least two other user equipment based on the accessed signal strength information,

program code to determine a user equipment pattern of the at least one user equipment and the at least two other user equipment based on the determined location of the at least one user equipment relative to the at least two other user equipment,

program code to derive a social context based on the determined user equipment pattern by comparing the determined user equipment pattern with predetermined patterns associated with different social contexts, and

program code to initiate an activity of the at least one user equipment in response to the derived social context.

12. The computer program product of claim 11, further comprising:

program code to dynamically track changes in the user equipment pattern; and

program code to derive the social context based on the tracked changes in the user equipment pattern.

13. The computer program product of claim 11, in which the program code to derive the social context further comprises one or more program code types selected from the group consisting of:

program code to determine a driver of a vehicle, program code to determine a speaker of a meeting, and program code to determine a teacher in a classroom.

14. The computer program product of claim 11, in which the program code to access signal strength information comprises program code to store one or more signal strength information types selected from the group consisting of:

Bluetooth signal strength information, Wireless Local Area Network (WLAN) signal strength, and ultrasound signal strength.

15. The computer program product of claim 11, in which the program code to initiate the activity further comprises one of:

program code to initiate a process to switch the at least one user equipment to a vibrate mode,

program code to initiate transfer of control of a shared application,

program code to compute a length of a queue and determine information about an average wait time of the queue,

program code to initiate launch of an application on the at least one user equipment, and

program code to route incoming text messages to passengers of a vehicle.
