  • Publication number: 20230032390
    Abstract: Techniques for improving the resiliency of communication networks by providing radio access network data stored in a radio access network database to one or more associated radio access network nodes are provided. A network entity receives a connection request from a user device including at least a radio access network set identifier or radio access network database identifier. The network entity determines whether the radio access network set identifier received in the connection request corresponds to an associated radio access network set identifier. In an instance in which the radio access network set identifier received in the connection request corresponds to the associated radio access network set identifier, radio access network database data are retrieved from the radio access network database associated with the radio access network set identifier. The radio access network database data include at least user device context data for the associated user device.

  • Publication number: 20220361134
    Abstract: A method, apparatus, and computer program product provide for adaptive paging for user equipment (UE) with multiple subscriber identification modules (SIMs). A UE may provide, in a registration message to the network, an indication that the UE supports multiple SIMs. The network may allow repeated paging to let a SIM miss a paging occasion without interpreting that the UE is unavailable. The indication from the UE can specify the number of SIMS supported by the UE. The network can adapt the number of paging repetitions to the UE. If the UE is accepting paging from another network or has a SIM that is already active with the network, the UE sends the network a paging control message. If the UE detects a paging occasion conflict, the UE sends the network a registration message with a replacement ID for paging another SIM, and the UE and the network negotiate appropriate paging.

  • Publication number: 20220321429
    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.
