Patent ID: 8239698

Claim:
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; circuitry configured to establish a communication link between said host system and an associated remote application server, said circuitry further configured to periodically transmit keep-alive messages to said remote application server while said host remains 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; and memory configured to store said keep-alive messages, said memory configured to be accessible to said circuitry while said host system remains in said low-power state; wherein said circuitry is further configured to transition 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; wherein said host system is further configured to generate additional keep-alive messages while in said second power state and transition back to said low-power state thereafter, and wherein said circuitry is further configured to transmit said additional keep-alive messages while said host system is in said low-power state, thereby maintaining connectivity and presence of said AOAC application with said remote application server while said host system is in said low-power state.
