Abstract:
1. A non-transitory computer-readable medium having stored thereon an executable agent component that directs a mobile electronic device to communicate with a monitoring center according to a protocol in which: during a first time period, the mobile device attempts to establish a communication session with the monitoring center over a computer network without use of a cellular network; if the attempt to establish the communication session over the computer network is unsuccessful, a call is placed over the cellular network between the mobile device and the monitoring center during a scheduled call time by connecting from a telephone number that is time-shared by multiple mobile devices, said scheduled call time falling after expiration of a time lag following the first time period; if the attempt to establish the communication session over the computer network is successful, the scheduled call time is made available to another mobile electronic device; and when a communication session is established between the mobile device and the monitoring center over the computer network or the cellular network, information is conveyed between the mobile device and the monitoring center to enable the monitoring center to track the mobile device; whereby the protocol conserves cellular network resources by attempting to convey said information to the monitoring center without use of the cellular network.
