Claim:
1. A method for optimized always-on wireless service, comprising: monitoring requests for always-on service from one or more applications or services on a user equipment (UE) that does not currently have always-on service from a network; transmitting, to the network, a message that requests a bearer dedicated to always-on service in response to receiving a request to register for the always-on service from at least one of the one or more applications or services on the UE; receiving, at the UE, an availability time that indicates a period during which the bearer dedicated to the always-on service will be held in an active state; and transmitting a keep-alive message from the UE to the network before the availability time expires, wherein the keep-alive message comprises information instructing the network to reset the availability time during which the dedicated bearer will be held in the active state without generating a reply message to the UE such that the UE does not receive keep-alive traffic from the network, and wherein the UE maintains the active state associated with the dedicated bearer and notifies the one or more applications or services that have registered for the always-on service to suppress application-layer keep-alive messages.
