Method and system for low power internetwork communication with machine devices
A wireless mobile device in a public communication network receives network-initiated signaling or messaging, while operating in a battery-conserving mode, or modes that, keep(s) minimal baseband processing functions awake. The baseband processing functions process incoming signaling or data in a received message to determine whether to act further on information in the incoming message by enabling additional processing capability in the mobile device. The mobile device may have permanent template criteria values, either coded in firmware or implemented in hardware, or temporary template criteria values, stored in RAM or processor registers, that are compared to values of an incoming message or datagram from the mobile network to determine whether to perform additional actions, such as awakening an application processor. Multiple templates may co-exist to allow different incoming datagrams to cause the device to take some additional action, respond, or even ignore information in an incoming datagram or message.
1. A system, comprising:
a first processor portion of a wireless user equipment device, wherein the first processor portion:
evaluates a received message to determine whether to provide an instruction to transition from a low power state by comparing at least one aspect of the received message to at least one transition from low power state criterion;
generates a transition from low power state instruction if the at least one aspect of the received message satisfies the at least one transition from low power state criterion; and
provides the transition from low power state instruction; and
wherein the wireless user equipment device uses a shared value, received by the wireless user equipment device before the wireless user equipment device received the received message, as an input to an algorithm to derive the at least one transition from low power state criterion.
2. The system of claim 1 further comprising a second processor portion wherein the instruction to transition from a low power state is provided to the second processor portion to cause the second processor portion to transition from a low power state, wherein the second processor portion generated the at least one transition from low power state criterion before the second processor entered the low power state.
3. The system of claim 1 further comprising a SIM card, wherein the algorithm is a cryptographic algorithm stored in the SIM card.
4. The system of claim 1 further comprising a memory that is accessible by the first processor portion, wherein the wireless user equipment device uses as an input to the algorithm the secret value stored in the memory to derive the at least one transition from low power state criterion, wherein the secret value is not included in the received message.
5. A method, comprising:
with a first processor portion of a wireless user equipment device:
evaluating a received message to determine whether to provide an instruction to transition from a low power state by comparing at least one aspect of the received message to at least one transition from low power state criterion;
generating a transition from low power state instruction if the at least one aspect of the received message satisfies the at least one transition from low power state criterion; and
providing the transition from low power state instruction; and
wherein the wireless user equipment device uses a shared value, received by the wireless user equipment device before the wireless user equipment device received the received message, as an input to an algorithm to derive the at least one transition from low power state criterion.
6. The method of claim 5 further comprising, with a second processor portion of the wireless user equipment device, generating the at least one transition from low power state criterion before the second processor enters the low power state.
7. The method of claim 5 further comprising, with the first processor portion, using as an input to a cryptographic algorithm a secret value stored in a memory of the wireless user equipment device to derive the at least one transition from low power state criterion, wherein the secret value is not included in the received message.
