Claim of US Patent No. 10,342,063

1. A method, implemented by a mobile device, of changing the discontinuous reception (DRX) configuration for a connection between a mobile device and a base station, the method comprising:receiving, from the base station, a control message indicating updated configuration parameters for the connection with the base station;
sending, by the mobile device, an acknowledgement of the control message;
continuing to use a current DRX configuration for the connection after receipt of the control message until a subsequent on duration of a DRX cycle according to the current DRX configuration has occurred, wherein length of the DRX cycle according to the updated configuration parameters is different from length of the DRX cycle according to the current DRX configuration;
computing a new DRX start offset for the updated DRX configuration as a function of a current DRX start offset for the current DRX configuration;
applying the updated configuration parameters for the connection in the subsequent on duration of the DRX cycle.
