Abstract: A network access node receives an indication of an interval between expected receptions of echo requests that pass through a tunnel that uses an interface between a network element in a core network of the cellular network to the network access node of the cellular network. The network access node determines a threshold time period based on the interval, detects there has been no echo request for a time period greater than the threshold time period, and determines that a failure has occurred of the tunnel that uses the interface. The network access node triggers set up of a new tunnel using the interface due to the failure of the tunnel. Multiple techniques are disclosed for determining that this failure has occurred and recovering from the failure, including setting up a new MBS session or using a new transport address for a current MBS session.

Abstract: According to an example embodiment, a network device is configured to:
generate an indicator based on at least one of an activation status of a multicast session or a data inactivity status; and transmit the indicator to a client device, wherein the indicator indicates to the client device whether the client device should wait for a paging message for the multicast session and stop monitoring data of the multicast session while the client device is in an inactive state.
