Patent ID: 8402289

Claim:
A method, comprising: establishing a plurality of communication links between a host system executing a plurality of Always-On-Always-Connected (AOAC) applications and respective remote application servers associated with each of said plurality of AOAC applications; 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 each of said plurality of AOAC applications; comparing a minimum time (Tapp) for each of said plurality of AOAC applications to maintain connectivity and presence with said respective remote server to determine a smallest Tapp (Tmin) for all of said plurality of AOAC applications; transitioning said host system from said first power state to said low-power state; and periodically transmitting said keep-alive messages from circuitry to said remote application servers for each of said plurality AOAC applications at a rate based on Tmin while said host system is in said low-power state, said keep-alive messages configured to maintain connectivity and presence of said AOAC applications with said remote application servers while said host system is in said low-power state.
