Techniques of preserving UE and network resources while performing a paging procedure during cell congestion includes a network node informing a UE if the cell to which the UE is attempting to access is too congested to serve the UE. When a gNB, serving a cell, receives a paging request for the gNB to serve a UE, the gNB first performs a pro-active admission control operation to determine whether there are sufficient resources to serve the UE. When there is too much congestion, the gNB may not admit the UE to the cell and sends RAN raging with a paging flag indicating that the gNB will not serve the UE. The UE in response does not trigger a service request, but rather sends an ACK paging over RRC to the gNB, which in turn notifies the AMF of non-service and that the UE is present.

Energy-efficient and RRC state aware radio resource allocation

Example embodiments of the invention provide at least apparatus for performing novel methods including receiving, by user device of a communication network, from a network node of the communication network at least one message including an access control indication, wherein the user device is in a radio resource control inactive state; and based on the user device meeting at least one requirement for use of the access control indication, performing operations comprising starting a random access procedure to enable at least one of an uplink or downlink data transmission between the user device and the communication network. In addition, at least apparatus for performing determining, by a network node of a communication network, at least one message comprising an access control indication for at least one user device, wherein the at least one user device is in a radio resource control inactive state; and communicating the at least one message with the at least one user equipment, wherein the at least one message is for causing operations comprising a random access procedure to enable communication with the communication network for use of the access control indication in response to the at least one user device meeting at least one requirement.
