摘要： Methods and apparatus are described of changing the discontinuous reception (DRX) configuration for a connection between a mobile device (50) and a base station (20) that reduces the likelihood of a dropped connection. A mobile device (50) receives updated configuration parameters for the connection from a base station. A mobile device (50) receives updated configuration parameters for the connection from a base station (20). The mobile device (50) postpones the adoption of the new configuration parameters and continues using previous configuration parameters for the connection after receipt of the new configuration parameters until a subsequent on duration of a DRX cycle has occurred according to the previous configuration. The mobile device (50) applies the updated configuration parameters for the connection in the subsequent on duration. Thereafter, the mobile device (50) turns its receiver on and off in DRX mode according to the new DRX configuration.

摘要： A node and method for extending a wake up time of a wireless user equipment (UE) are provided. The node includes a memory. The memory is configured to store data to be transmitted to the UE. The node includes a processor configured to determine if the memory is storing data to be transmitted to the UE, determine if the wake up time of the UE coincides with a periodic subframe, the periodic subframe occurring with a periodicity and cause transmission of a message for a grant to the UE if the determination is made that the memory is storing data to be transmitted to the UE and the wake up time of the UE coincides with the periodic subframe.
