Electronic Device That Processes Data Received from an External Apparatus

摘要

An electronic device may include a main system that can operate in a normal state and an energy-saving state, a data retaining unit that stores data, and a subsystem that may execute transmission and reception of data to and from an external apparatus. While the main system is in the energy-saving state, if the subsystem receives main dedicated specific data of pieces of main dedicated data required to be processed by the main system, the subsystem may store the main dedicated specific data. While the main system is in the energy-saving state, if the subsystem receives main dedicated data other than the main dedicated specific data from an external apparatus, the subsystem may transition the main system to the normal state and cause the main system to process the main dedicated specific data stored and the main dedicated data other than the main dedicated specific data.

1. An electronic device comprising:
a main system that operates in (i) a normal state or (ii) an energy saving state, and wherein energy consumed by the electronic device in the energy-saving state is less than energy consumed by the electronic device in the normal state; a data retaining unit that stores data; a network communication unit that communicates with an external apparatus; and a subsystem that:
receives, via the network communication unit, a packet from an external apparatus;provides the received packet to the main system to process the received packet;receives a response packet generated by the main system as a result of processing the received packet;upon receiving the response packet, transmits the response packet to the external apparatus via the network communication unit;determines whether the transmitted response packet corresponds to main dedicated specific data;based on determining that the transmitted response packet does not correspond to main dedicated specific data, stores response generation information associated with the transmitted response packet in the data retaining unit;determines whether the transmitted response packet corresponds to a command to transition the main system from the normal state to the energy saving state; andbased on determining that the transmitted response packet corresponds to a command to transition the main system from the normal state to the energy saving state, transitions the main system from the normal state to the energy saving state.
