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.

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: A communication management resource receives notification of a registration request associated with user equipment present in a wireless network environment. In response to receiving the registration request, the communication management resource executes a roaming management function on behalf of the user equipment. Via the roaming management function, the communication management resource manages roaming of the user equipment in the wireless network environment. Using an SoR type mechanism as described herein allows a PLMN/SNPN operator to control their subscribers to what roaming SNPN network that they should select/reselect during wireless registration and at any time after registration based on the type of wireless services.

Abstract: A communication management resource receives notification of a request from user equipment to establish a wireless communication link with a remote communication device through a first private wireless network. The communication management resource resides in a second private wireless network to which the user of the user equipment is a member. The request requests use of services provided by the second private wireless network to connect the user equipment to a remote communication device. In response to receiving the request, the second private wireless network retrieves a unique network identifier value assigned to the first private network. Via the unique network identifier value, the communication management resource detects that the first private wireless network is associated with the second wireless network. Based on the association, the communication management resource support communications between the user equipment and the remote communication device.

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: Apparatus and methods for registration of e.g., mobile devices in one or more wireless networks. In one embodiment, the apparatus and methods provide enhanced wireless services which enable operation of a given mobile device (e.g., a 3GPP-compliant UE) within two or more mobile networks (e.g., PLMNs) of respective different operators. In one implementation, the UE operates in dual-registration mode or DRM to allow different interworking between the two networks, and includes independent registration capability to 5GC and EPC infrastructure simultaneously. Accordingly, the UE is provided umbrella 4G/4.5G coverage over one or more small-cell 5G networks, with respective independent operators of each. Enhanced DRM-UEe capability as described herein advantageously allows for service provision (e.g., voice service) and interworking between the macro and small-cell layers of the system without complicated network configuration requirements between the two operating networks.

Abstract: Efficient paging in a communications system including macro and small cell base stations is described. A macro cell base station receives, from a network node, a request to page a UE and determines a set of base stations including one or more small cell base stations, which are to attempt to page the UE. The macro cell base station communicates the paging request to the selected one or more small cell base stations. A small cell base station, using unlicensed spectrum, may fail in its paging attempt due to current unavailibity of the unlicensed spectrum (LBT fails to clear) resulting in no paging signal transmitted; the reason for failure is communicated from the small cell base station to the macro cell base station via a paging response message. The macro cell base station in turn communicates a paging response message to the network node communicating the reason for failure.

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.

Abstract: Data packet congestion marking is supported in devices which may form part of a communications path. The devices which can perform marking can, and in some embodiments do, include non-gNB devices and non-anchor point UPFs, e.g., devices other than gNBs and PSA UPFs such as intermediate UPFs, N3IWFs, TNGFs, and W-AGFs, in addition to gNBs and anchor UPFs. Intermediate UPFs corresponding to a communications session will set the congestion indicator value in a data packet's IP header, of a data packet passing through the UPF, to indicate congestion, if it is not already set to indicate congestion when congestion is detected at the intermediate UPF. A session management function in some embodiments controls which devices perform congestion marking and enables/disables congestion marking, e.g., on a per communications session basis while the session is ongoing and/or at various times during a session establishment or device registration process.
