UE Wake-up Ahead of Paging Occasions to Retrieve Paging Configuration Information when in (Long) DRX
First Claim
1. A method for transmission of paging information from a mobile network to a terminal device, the method comprising:
- according to a discontinuous reception cycle, the terminal device entering a sleep mode in which the terminal device is not monitoring a downlink control channel transmitted by the mobile network;
the terminal device determining an advance wakeup time for leaving the sleep mode, said advance wakeup time being advanced by an advancement time interval with respect to a start of an active time of the discontinuous reception cycle;
at the determined advance wakeup time, the terminal device leaving the sleep mode and starting monitoring the downlink control channel with respect to paging configuration information from the mobile network, the paging configuration information defining a paging occasion for the transmission of the paging information; and
on the basis of the paging configuration information, the terminal device monitoring the paging occasion to receive the paging information from the mobile network.

Abstract
In transmission of paging information from a mobile network to a terminal device (200), the terminal device applies a discontinuous reception cycle to enter a sleep mode. Further, the terminal device determines an advance wakeup time (AW) for leaving the sleep mode. The advance wakeup time (AW) is advanced by an advancement time interval (ΔA) with respect to a start of an active time of the discontinuous reception cycle. At the determined advance wakeup time (AW), the terminal device leaves the sleep mode and starts monitoring the downlink control channel with respect to paging configuration information transmitted by the mobile network. The paging configuration information defines a paging occasion for transmission of the paging information. On the basis of the paging configuration information, the terminal device monitors the paging occasion to receive the paging information from the mobile network.
