  • Patent number: 11638316
    Abstract: Systems and methods to support coexistence of multi-connectivity functions in 3GPP network and non-3GPP networks for UEs and to provide traffic routing policies and coordinate with ATSSS operation in 5GS are described. The AF subscribes to a registration-state notification event. A report is sent to the AF from the PCF or NEF. The report indicates a current registration state of a UE and is triggered when the registration state of the UE changes. The report may be sent with or without PDU session information, the former of which may be based on a determination by the AMF or the SMF. Traffic steering is enforced by the MAMS among multiple IP sessions coordinated via a single or a multiple PDU sessions in the 3GPP network.

  • Patent number: 11601869
    Abstract: In one embodiment, an apparatus of a User Equipment (UE) device includes memory storing non-public network (NPN) configuration information, a radio frequency (RF) interface, and processing circuitry coupled to the memory and the RF interface. The RF interface receives information broadcast by a radio access network (RAN) node of the particular NPN, where the information includes a NPN indicator indicating that the RAN node supports a NPN and NPN service information indicating services supported by the particular NPN. The processing circuitry establishes, in response to detecting the NPN indicator in the information received from the RAN node, a connection to the particular NPN based on the NPN configuration information and the NPN service information received from the RAN node.

  • Publication number: 20220394552
    Abstract: Methods, apparatus circuitry, and storage media are described for mobile-terminated packet transmissions. In one embodiment, an apparatus of a control plane device configured to operate within an evolved packet network core identifies a first service flow event trigger associated with a first packet data unit (PDU) session and processes a path reselection for a first PDU session in response to the first service flow event trigger, wherein the path reselection determines a new gateway for the first PDU session resulting from the path reselection. Transmission of a change notification to an application server controller associated with the first PDU session is initiated in response to the path reselection. Transmission of a routing update to the new gateway in response to the path reselection is also initiated. In various embodiments, the trigger may be a mobility event, a load balancing event, or operations in association with an application server controller.

  • Publication number: 20220159616
    Abstract: In an example method, a user equipment (UE) determines a first identifier assigned to the UE for use on a first wireless communications network and one or more first time slots for monitoring the first wireless communication networks. The UE determines a second identifier assigned to the UE for use on a second wireless communications network and one or more second time slots for monitoring the second wireless communication networks. The UE determines that the one or more first time slots at least partially overlap the one or more second time slots, and in response, transmits to the second wireless communications network, a request for a third identifier to be assigned to the UE for use on the second wireless communications network and/or a request that the one or more second time slots be offset by an interval of time.
