  • Patent number: 11956671
    Abstract: A 5G network having a multi-path transport protocol (MPTP) proxy external to the user plane function (UPF). The session management function (SMF) provides address information of the external MPTP proxy to user equipment (UE) and distributes access traffic steering, switching, and splitting (ATSSS)-related rules to the UE, the UPF, and the external MPTP proxy. The external MPTP proxy receives, from the UPF, (i) 3GPP uplink data transmitted by the UE via a 3GPP radio access network (RAN) and (ii) non-3GPP uplink data transmitted by the UE via a non-3GPP RAN, combines the 3GPP and non-3GPP uplink data to form network uplink data for a data network. The external MPTP proxy also divides received network downlink data into 3GPP downlink data and non-3GPP downlink data, and provides the 3GPP and non-3GPP downlink data to the UPF for transmission to the UE via the 3GPP RAN and the non-3GPP RAN, respectively.

  • Publication number: 20230397046
    Abstract: Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for managing UE migration or offloading from mobile network operators (MNO) cells to mobile virtual network operators (MVNO) cells (optionally access points) in a dual-network deployment use case by identifying and communicating one or more dynamic traffic offload policies to UE(s) based information provided by MVNO subscriber UEs and/or information generated by the network itself. In this manner, the MVNO network operator may control an amount of traffic in the MVNO small cell network while avoiding or at least reducing negative end-user experience. In various embodiments, the UE offloaded from the MNO to the MVNO may be roaming UE associated with a different MVNO.

  • Publication number: 20230354242
    Abstract: Methods and apparatus for supporting efficient switching of data paths corresponding to a communications session between different non-3GPP access networks, e.g., networks including WiFi access points, using network core functionality are described. A novel registration process in which UE and AMF capability information is exchanged at an early stage in the registration process is described. An initial registration request message from a UE, via a 3GPP or N3GPP access network, includes an indicator as to whether or not the UE supports path switching for MA PDU sessions between N3GPP access paths. This allows, for a UE which supports the path switching, a AMF to be selected and assigned to the UE, which also supports the path switching, thus matching capabilities and eliminating the need for interrupting communications to change AMFs at a later point.

  • Publication number: 20230308971
    Abstract: Methods and apparatus for supporting switching of data paths corresponding to a communications session between different non-3GPP access networks, e.g., networks including WiFi access points, using network core functionality are described. This allows a communications session in which a UE is involved as an end point to be switched between two different WiFi access networks and/or a WiFi access network and a 3GPP access network, e.g., cellular access network, without the communications session being terminated while service is provided to the UE by a Public Land Mobile Network (PLMN) with which it is registered. A UE can switch between multiple WiFi networks while maintaining a communications session supported by network core functionality even though the session may be switched between different non-3GPP networks while the session is ongoing.

  • Publication number: 20230262650
    Abstract: Apparatus and methods for managed or “intelligent” paging of a user device in one or more wireless networks. In one embodiment, the apparatus and methods provide enhanced wireless services which enable prioritized paging operations of a given user device (e.g., a mobile 3GPP-compliant UE) within two or more mobile networks (e.g., PLMNs) when the UE is operating in a “dual” mode such as 3GPP 5G NR dual-SIM, dual standby (DSDS) mode. In one implementation, the UE contains multiple SIM cards to enable connection to different PLMNs simultaneously, such that paging associated with one network can be managed and prioritized as needed when the UE is actively utilizing another network.

  • Patent number: 11606743
    Abstract: A radio access network (RAN) for a wireless communication network transmits, to user equipment (UE), information about NPN services provided by a non-public network (NPN) supported by the wireless network, where the UE is not subscribed to the NPN. In some embodiments, the NPN service information is periodically broadcasted to the UE; in other embodiments, the information is transmitted in response to receiving a request from the UE. In response to receiving the NPN service information, the UE transmits and the RAN receives an on-boarding request from the UE to on-board the UE to the NPN, which the RAN forwards to an on-boarding network (OBN) of the wireless network. In response, the RAN receives NPN credentials for the UE from the OBN, which the RAN forwards to the UE, which uses the NPN credentials to register to the NPN, thereby enabling the non-subscribing UE to subscribe to the NPN.

  • Patent number: 11343795
    Abstract: Methods and apparatus for efficient paging in a communications system using unlicensed spectrum are described. A base station, which uses unlicensed spectrum, receives a paging request message from a network node and performs paging operations attempting to page the UE. The paging attempt may fail due to the base station being unable to transmit a paging signal to the UE because the unlicensed spectrum is currently unavailable or because the UE did not respond to a transmitted page. The base station generates and transmits a paging failure response message including a failure cause code indicating the reason that the paging attempt failed. The network node receives the paging failure response message, recovers the failure cause code, and implements a paging escalation strategy as a function of the recovered failure cause code.
