Abstract: Apparatus and methods for prioritizing spectrum and controlling data traffic steering within a wireless network. In one embodiment, the apparatus and methods provide enhanced wireless services which allow network operators to prioritize utilization of spectrum for their subscribers. In one variant, an enhanced 3GPP UE Route Selection Policy (URSP) framework is provided for a UE connected to 5G wireless network, which allows the UE to use one or more prioritized 3GPP spectrum Band Class(es) based on one or more selection criterion or preconditions. In another variant, UE location information is used to dynamically update a data traffic steering mode or other functionality of an enhanced ATSSS (Access Traffic Steering, Switching, and Splitting) rule framework is described for dynamic control of steering or routing functionality, including between 3GPP- and non-3GPP network accesses for the data traffic.

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.

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.

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.

Abstract: Apparatus and methods for interworking a user device in one or more wireless networks. In one embodiment, the apparatus and methods provide enhanced wireless services which enable operation of a given user device (e.g., a mobile 3GPP-compliant UE) within two or more mobile networks (e.g., PLMNs), such as a macro network and micro network. In one implementation, the UE contains multiple SIM cards to enable connection to different networks simultaneously. Accordingly, the UE can roam between two different networks seamlessly, regardless of whether the operators of each are independent or the same operator. Enhanced network capability as described herein advantageously allows for interworking between the macro and micro (e.g., small-cell) layers of the system without complicated network configuration requirements between the two operating networks as required under the prior art.

Abstract: Methods and apparatus for providing bandwidth which can be used to support network connectivity and to obtain services from elements in a network, e.g., 5G network, are described. In various embodiments a DOCSIS link is connects a residential gateway at a customer premises to devices outside the customer premises, e.g., to devices in a 5G network or another network. Devices which support EAP authentication are provided with their dedicated bandwidth over the DOCSIS link. Devices which do not support EAP authentication, e,g, WiFi devices, share bandwidth to which a subscriber residing at the customer premise subscribes. Devices which support EAP authentication are provided reserved resources corresponding to a subscription associated with the individual device thereby allowing a user of a device which supports EAP authentication to obtain more bandwidth than is normally provided to a visited premises based on the service subscription associated with the visiting device.

Abstract: In various embodiments an explicit congestion feedback capabilities indication, e.g., information indicating a UE's support or lack of support for low latency, low loss and scalable throughput services (L4S), is communicated in a message sent from a UE to device in a network core. In some embodiments the communicated UE capability information provides information about the capability of the UE sending the message to support the use of feedback (e.g., congestion feedback) for scalable throughput services (e.g., (L4S services) or other explicit congestion notification (ECN) services which use congestion feedback for encoding and/or data rate control). In some embodiments the message or messages communicating the UE capability information include a PDU Session Establishment Request message, a PDU Session Modification Request message, and/or a Registration Request message.
