  • Patent number: 11368375
    Abstract: A method, apparatus and computer program product are provided herein to receive, from a source, performance requirements, and cause transmission, to a network, of a request to influence time sensitive communications (TSC) configuration parameters. For example, a method is provided to in response to the request to influence TSC configuration, receive, from the network, network configuration and radio access network (RAN) resource constraints and determine a quality of service (QoS) and the TSC configuration parameters to support a TSC data stream based on the performance requirements received from the source, the network configuration, and the RAN resource constraints. The method is further configured to cause transmission of the determined QoS and the TSC configuration parameters to the network and the source and in an instance the network accepts the determined QoS and the TSC configuration parameters, configure resources for the TSC data stream and continuously support service continuity.

  • Publication number: 20220174640
    Abstract: A determination is made that a registration attempt by a UE with a cell of a wireless network has failed when the UE is in a current tracking area. The UE updates a first list with indications(s) corresponding to the cell and an indication of the current tracking area, and the UE uses the first list for additional registration attempts. A network node sends, toward the UE, a request for the UE to store information, the storing to be in response to registration attempts by the UE with cells of the wireless network having failed while in corresponding tracking areas. The information is to include indication(s) corresponding to the cells and corresponding indication(s) of the tracking areas for the cells. The network node receives, in response to a successful secure connection having been performed between the wireless network and the UE, the information from the user equipment.
