An apparatus is provided for use by a network agent element or function to conduct link layer information related processing. The apparatus is caused to receive first link layer related information from a neighboring network element or function, forward second link layer related information to a communication network control element or function, receive third link layer related information from a communication network control element or function, and forward fourth link layer related information to a neighboring network element or function. The second and fourth link layer related information are generated using first and third link layer related information, respectively. The second and third link layer related information is received and forwarded via a wireless connection path of a wireless communication network. The apparatus is connected to or part of the/or communication element or function, a communication network control element or function and a communication network data element or function.

An example method includes: establishing time synchronization within a network comprising a plurality of nodes using a time source; receiving an indication regarding at least one of degradation or failure of the time source for at least one node; receiving an indication regarding at least recovery of the time source for the at least one node; and determining, within the network, an action to be taken to upon failure at the at least one node in response to the at least one of the degradation or the failure of the time source for the at least one node, where the action to be taken comprises instructing the at least one node to leverage either hold over functionality or a backup time source.

Time source health monitoring support for network timing resiliency

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.
