  • Publication number: 20240007902
    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.

  • Patent number: 11856652
    Abstract: Systems and methods provide solutions for reliable data transfer in a mobile communication network. A user equipment (UE) may indicate to the mobile communication network a capability of the UE to support a reliable data service protocol. The UE may process non-access stratum (NAS) messages, for both mobile originated (MO) data transfer and mobile terminated (MT) data transfer, using the reliable data service protocol to determine whether protocol data units (PDUs) of the NAS messages require no acknowledgement, require acknowledgment, or include an acknowledgement, and to detect and eliminate duplicate PDUs received at the UE in the NAS messages.

    Abstract: Disclosed embodiments are related to configuring and/or provisioning user equipment (UE) for Multicast-Broadcast Service (MBS). The present disclosure provides embodiments to allow a Fifth Generation System (5GS) to configure the MBS sessions based on Quality of Service (QoS) conditions of the receptions of MBS session of the UEs (subscribers). As such, the 5GS is able to provide differentiated QoS flows in the MBS session to UEs, which may have different service subscription in the 5GS and user subscriptions for MBS applications. Other embodiments may be described and/or claimed.

  • 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.
