CONNECTION RESUME PROCEDURE FOR UE IN EDRX AND RRC INACTIVE STATE FOR MT DATA

Abstract:

Techniques, systems, and devices to support user equipment (UE) in an extended discontinuous reception mode are described. A described technique performed by a radio access network (RAN) includes managing UE that is in an extended discontinuous reception mode and in an inactive state; sending a notification message to an access and mobility management function (AMF), the message comprising buffer support information for a user plane function (UPF) to buffer data; receiving a notification request message from the AMF, the notification request message comprising a request to obtain information regarding reachability of the UE; sending a notification response message to control when the UPF provides downlink data to the RAN for transmission to the UE; performing a connection resume procedure with the UE to cause the UE to switch to a connected state from the inactive state; receiving the downlink data; and transmitting the downlink data to the UE.
