  • Patent number: 12369054
    Abstract: Embodiments include methods for failure reporting by a user equipment (UE) operating in a cell of a first network. Such methods include sending, to a network node serving the cell, a message that includes a first indication of availability of one or more failure reports. Each available failure report corresponds to a failure that occurred while the UE was operating in the first network, a network different than the first network, or a network of a different type than the first network. Such methods also include receiving, from the network node, a request for at least a portion of the failure reports indicated as available by the first indication; and sending at least one of the available failure reports to the network node in accordance with the request. Other embodiments include complementary methods for a network node as well as UEs and network nodes configured to perform such methods.
