Method of controlling operation of a communication device, transceiver operating accordingly, and computer program

摘要

A communication device is arranged for three main communication states: a detached state, an idle state, and an active state. The communication device connects to the cellular communication network such that a transition from the detached state to any of idle state or active state is made, performs scheduled operations in the active state or idle state, determines, when a transition from the active state to the idle state occurs, a time instant for a next operation in the active state, disconnects from the cellular communication network such that a transition to the detached state is made, and, when the time for next operation in the active state is approaching, connects to the cellular communication network again. A transceiver and a computer program are also disclosed.

1. A method of controlling operation of a communication device arranged to operate in a cellular communication network employing a paging signal to allow discontinuous reception for communication devices, wherein the communication device is arranged for three main communication states:
a detached state where the communication device is not registered to the cellular communication network; an idle state where the communication device is registered to the cellular communication network, and receives paging signals through discontinuous reception; and an active state where the communication device is registered to the cellular communication network and performs communication with the cellular communication network essentially continuously,wherein the communication device is arranged for the power save mode of the detached state and the method comprises
performing scheduled operations; and entering the power saving mode when activities in the active state are not imminent,
wherein the entering of the power saving mode comprises disconnecting from thecellular communication network,and wherein the method further comprises, when disconnected, reconnecting to the cellular communication network when a time for next operation in the active state or scheduled operations in the idle state is approaching.
