Abstract

Methods and systems for seamless context transfers include receiving a context object from one or more applications, where the context object including updated context information for a user having an associated timestamp; entering the updated context information into a context information database; determining entries of the context information database for the user having a timestamp older than a predetermined threshold using a processor; purging the determined entries from the context information database; and sending an updated context object to one or more applications that reflects a current state of the context information for the user.

Claims

1. A method for seamless context transfers, comprising:

receiving a context object from one or more applications, said context object including updated context information for a user having an associated timestamp;

entering the updated context information into a context information database;

determining entries of the context information database for the user having a timestamp older than a predetermined threshold using a processor;

purging said determined entries from the context information database; and

sending an updated context object to one or more applications that reflects a current state of the context information for the user.

2. The method of claim 1, wherein the predetermined threshold is based on a particular kind of context information that a determined entry belongs to.

3. The method of claim 1, further comprising receiving a request for an updated context application from one or more applications, wherein sending the updated context object is responsive to said request receipt.

4. The method of claim 1, wherein updated context objects are sent according to a predefined schedule.

5. The method of claim 1, wherein updated context objects are sent immediately upon entering updated context information into or purging entries from the context information database.

6. A system for seamless context transfer, comprising:

a receiver configured to receive a context object from one or more applications, said context object including updated context information for a user having an associated timestamp;

a processor configured to enter the updated context information into a context information database, to determine entries of the context information database for the user having a timestamp older than a predefined threshold using a processor, and to purge said determined entries from the context information database; and

a transmitter configured to send an updated context object to one or more applications that reflects a current state of the context information for the user.

7. The system of claim 6, wherein the predetermined threshold is based on a particular kind of context information that a determined entry belongs to.

8. The system of claim 6, wherein the receiver is further configured to receive a request for an updated context application from one or more applications and wherein the transmitter is configured to send the updated context object responsive to said request receipt.

9. The system of claim 6, wherein updated context objects are sent according to a predefined schedule.

10. The system of claim 6, wherein updated context objects are sent immediately upon entering updated context information into or purging entries from the context information database.
