Method of Controlling Operation of a Communication Device, Transceiver Operating Accordingly, and Computer Program

摘要

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 is disclosed. The communication device is arranged for three main communication states: detached state where the communication device is not registered to the cellular communication network; idle state where the communication device is registered to the cellular communication network, and receives paging signals through discontinuous reception; and active state where the communication device is registered to the cellular communication network and performs communication with the cellular communication network essentially continuously. The method comprises: i) connecting to the cellular communication network such that a transition from the detached state to any of idle state or active state is made; ii) performing scheduled operations in the active state or idle state; iii) determining, when a transition from the active state to the idle state occurs, time instant for next operation in the active state; iv) disconnecting from the cellular communication network such that a transition to the detached state is made; and v) when the time for next operation in the active state is approaching, returning the procedure to step i). A transceiver and a computer program are also disclosed.
