1. A mobile management entity (MME) of a telecommunication network comprising:
- a receiver;
a transmitter; and
a processor coupled to the receiver and the transmitter, the processor being configured to;
receive, via the receiver, a downlink data notification message from a gateway;
determine from the downlink data notification message that there is downlink data for user equipment (UE), the downlink data not being deliverable to the UE due to the UE being in a power saving mode;
receive, via the receiver, a tracking area update (TAU) request from the UE; and
send to a base station, via the transmitter upon receiving the TAU request, an initial UE context setup request message to request the base station to set up a data bearer with the UE and to notify the UE that there is the downlink data for the UE, the initial UE context setup request message being sent without sending a paging message to the UE.

Abstract
A method for saving power of UE and a device. The method includes, when determining that downlink data to be sent to UE exists and that the UE is in a power saving mode, recording an event that the downlink data to be sent to the UE exists when the user equipment (UE) is in a power saving mode; and sending, when receiving a tracking area update (TAU) request initiated by the UE, an indication message to the UE, where the indication message is used to indicate that the downlink data to be sent to the UE exists when the UE is in a power saving mode so that the UE obtains the downlink data after setting up a data bearer.

4. A method performed by a mobility management entity (MME) of a telecommunication network for communicating with user equipment (UE), the method comprising:
-
receiving a downlink data notification message from a gateway; determining from the downlink data notification message that there is downlink data for the UE, the downlink data not being deliverable to the UE due to the UE being in a power saving mode; receiving a tracking area update (TAU) request from the UE; and sending to a base station, upon receiving the TAU request, an initial UE context setup request message to request the base station to set up a data bearer with the UE and to notify the UE that there is the downlink data for the UE, the initial UE context setup request message being sent without sending a paging message to the UE. - View Dependent Claims (5, 6)

7. A non-transitory computer-readable storage medium comprising instructions which, when executed by a processor of a mobility management entity (MME) of a telecommunication network, cause the MME to perform operations comprising:
-
receiving a downlink data notification message from a gateway; determining from the downlink data notification message that there is downlink data for user equipment (UE), the downlink data not being deliverable to the UE due to the UE being in a power saving mode; receiving a tracking area update (TAU) request from the UE; and sending to a base station, upon receiving the TAU request, an initial UE context setup request message to request the base station to set up a data bearer with the UE and to notify the UE that there is the downlink data for the UE, the initial UE context setup request message being sent without sending a paging message to the UE. - View Dependent Claims (8, 9)
