Patent ID: 7961756

Claim:
A system of communicating a data set between a battery powered, wireless mobile device and a remote device, the system incorporating a wireless communications link between the wireless mobile device and a wireless communications network, the wireless mobile device comprising: a wireless communication module; an input/output unit effectively connected to the wireless communication module; a microprocessor effectively connected to the input/output unit, wherein the microprocessor includes memory, a real time clock, a communications processor including (i) a first upper layer module configured to execute one or more upper layer protocols and (ii) a data link layer configured to execute a data link layer protocol, and a host processor operable by a control program, the host processor configured to (i) process a first data set to packetize the first data set for transmission to the remote device, or ii) process packets of a second data set received from the remote device to produce the second data set, wherein the communications processor is configured to execute only the data link layer protocol and none of the one or more upper layer protocols when the communications processor operates in a first state, and execute the data link layer protocol and the one or more upper layer protocols when the communications processor operates in a second state, and wherein the host processor includes a second upper layer module configured to execute the one or more upper layer protocols; a switching module configured to cause the communications processor to operate in the first state or the second state; and a power saving module configured to prevent the host processor from executing the one or more upper layer protocols executed by the communications processor when the communications processor operates in the second state.
