1. A method, comprising:
- establishing a communication link between a host system executing an Always-On-Always-Connected (AOAC) application and a remote application server associated with said AOAC application;
receiving an indication to transition a host system from a first power state to a low-power state;
initiating the generation of a plurality of keep-alive messages associated with said AOAC application;
generating a general keep-alive message and a list of security tokens;
transitioning said host system from said first power state to said low-power state;
assembling said general keep-alive message with a respective one of said security tokens from said list to generate said keep-alive message after said host system transitions to said low-power state; and
periodically transmitting said keep-alive messages from circuitry to said remote application server while said host system is in said low-power state, said keep-alive messages configured to maintain connectivity and presence of said AOAC application with said remote application server while said host system is in said low-power state.

Abstract
A system and method for maintaining connectivity between a host system running an Always-On-Always-Connected (AOAC) application and an associated remote application server. The system further includes circuitry configured to establish a communication link between the host system and the remote application server. The circuitry is configured periodically transmit keep-alive messages to the remote application server after the host system transitions to and remains in a low-power state. The keep-alive messages are configured to maintain connectivity and presence of the AOAC application with the remote application server while the host system is in the low-power state.

4. A system, comprising:
-
a host system configured to operate in a first power state and a low-power state, said host system further configured to execute at least one Always-On-Always-Connected (AOAC) application while in said first power state, said host system further configured to generate at least one partially pre-built keep-alive message; circuitry configured to establish a communication link between said host system and a remote application server associated with said AOAC application, said circuitry further configured to generate one or more keep-alive messages from said at least one partially pre-built keep-alive message and to periodically transmit said one or more keep-alive messages to said remote application server upon said host system transitioning from said first power state to said low-power state, said keep-alive messages configured to maintain connectivity and presence of said AOAC application with said remote application server while said host system is in said low-power state; and memory configured to store said one or more keep-alive messages, said memory configured to be accessible to said circuitry while said host system remains in said low-power state. - View Dependent Claims (5, 6, 7)

8. An apparatus, comprising:
-
circuitry configured to establish a communication link between a host system executing an Always-On-Always-Connected (AOAC) application in a first power state and a remote application server associated with said AOAC application, said circuitry further configured to generate one or more keep-alive messages from at least one partially pre-built keep-alive message and to periodically transmit said one or more keep-alive messages associated with said AOAC application to said remote application server upon said host system transitioning from said first power state to a low-power state, said keep-alive messages configured to maintain connectivity and presence of said AOAC application with said remote application server while said host system is in said low-power state; wherein said keep-alive messages are stored in memory accessible to said circuitry while said host system remains in said low-power state. - View Dependent Claims (9, 10, 11)

12. At least one non-transitory computer accessible medium storing instructions which, when executed by a machine, cause the machine to perform operations, said operations comprising:
-
generating one or more keep-alive messages from at least one partially pre-built keep-alive message after said host system has transitioned from a first power state to a low-power state, said one or more keep-alive messages associated with an Always-On-Always-Connected (AOAC) application having a communication link between a host system and a remote application server associated with said AOAC application; and periodically transmitting said keep-alive messages from circuitry associated with said host system to said remote application server while said host system is in said low-power state, said keep-alive messages configured to maintain connectivity and presence of said AOAC application with said remote application server while said host system is in said low-power state. - View Dependent Claims (13, 14, 15)

16. A method, comprising:
-
establishing a communication link between a host system executing an Always-On-Always-Connected (AOAC) application and a remote application server associated with said AOAC application; receiving an indication to transition a host system from a first power state to a low-power state; initiating the generation of a plurality of keep-alive messages associated with said AOAC application; transitioning said host system from said first power state to said low-power state; periodically transmitting said keep-alive messages from circuitry to said remote application server while said host system is in said low-power state, said keep-alive messages configured to maintain connectivity and presence of said AOAC application with said remote application server while said host system is in said low-power state; transitioning said host system from said low-power state to a second power state when a remaining number of keep-alive messages in said memory reaches a threshold; generating additional keep-alive messages while in said second power state and transitioning back to said low-power state thereafter; and transmitting said additional keep-alive messages while said host system is in said low-power state. - View Dependent Claims (17, 18)
