Embodiments provide a core network selection method, an apparatus, and a system. The method includes the following steps: obtaining first dedicated core network (DCN) information from an access network device, where the first DCN information includes information about at least one DCN that can be accessed by the access network device. The method also includes selecting a to-be-accessed DCN from the at least one DCN according to the first DCN information, and sending information about the to-be-accessed DCN to the access network device, so that the access network device determines a core network device according to the information about the to-be-accessed DCN.

A neighboring cell determines that uplink interference from an unmanned aerial vehicle (UAV) exceeds a first threshold at the neighboring cell. The neighboring cell transmits an uplink interference indicator to the UAV. In some examples, the UAV informs its serving cell of the uplink interference experienced by the neighboring cell. The serving cell can utilize information received from the UAV to make handover decisions or scheduling decisions for the UAV that caused the uplink interference. In other examples, the UAV can temporarily refrain from transmitting on at least some of its uplink resources or utilize different uplink resources for uplink data transmissions. In still other examples, the UAV can utilize downlink measurements to select which neighboring base station System Information Block messages should be monitored for an uplink interference indicator.

Apparatuses, methods, and systems are disclosed for indicating data status to a target base unit. One apparatus includes a transceiver that communicates with a remote unit and a processor that determines to perform a conditional handover of the remote unit to a target base unit. The processor sends a conditional handover command to the remote unit, the conditional handover command including at least one condition the remote unit is to monitor for fulfillment prior to handing over to the target base unit. The processor receives uplink data from the remote unit after sending the conditional handover command and forwards the uplink data to the target base unit. The processor also sends an end marker to the target base unit in response to completing the forwarding of the uplink data.

Novel techniques are described for generation, distribution, and management of route connectivity optimization (RCO) mapping. For example, as mobile devices traverse travel routes serviced by one or more mobile networks, they can experience periods of different levels of connectivity with the mobile network(s). Embodiments can collect route segment connectivity data as experienced by consumer devices during traversal through mobile networks (e.g., indicating, for each route segment, which carriers are providing service to a mobile device, the level of service being provided, etc.). A RCO can be computed and stored for the set of route segments as a function of the route segment connectivity data. The RCO can be requested by consumers, and a corresponding link can be generated. Selecting the link can provide the consumers with remote access to the RCO, with which the consumers can generate connectivity-optimized route guidance maps.

A network environment includes a first station, a second station, and a communication manager. The communication manager monitors a backhaul between the first station and the second station. In one arrangement, the first station is a wireless access point providing wireless connectivity to multiple mobile communication devices. During operation, the backhaul conveys communications between the first station and the second station. Based on the monitoring, the communication manager produces a metric indicating an ability of the backhaul to convey communications. Based on the metric, the communication manager determines a split of multiple processing layers in a wireless protocol stack. To accommodate the split, the communication manager assigns a first portion of multiple network communication layers to the first station for processing and a second portion of the multiple network communication layers to the second station for processing.

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for a media device operating on a first network that can detect and switch media service to a second network to maintain access of a desired service quality. The media device can cause a presentation of the recommended second network, and receive a selection (e.g., user input) of the second network before the switch. The recommendation can be user-initiated or occur while accessing service without user initiation. The recommendation of the second network can be based on: a signal quality of the second network and/or the capabilities of the device providing the second network; a correlation of characteristics that indicate that stored credentials of a first network can be reused in another network; a security level of the first network; and/or platform capabilities of the media device.

Systems and methods for Orthogonal Frequency-Division Multiple Access (OFDMA) optimized steering in Wi-Fi networks (10, 10A, 32). The present disclosure contemplates operation in a multiple access point network (14, 36) utilizing OFDMA technology, e.g., IEEE 802.11ax, where clients are connected to the access points considering the effect on OFDMA operation depending on where the clients are connected. That is, the present disclosure considers OFDMA operation in the context of optimization in a distributed or multiple access point network (14, 36). The optimization decision is based on capabilities of client devices and/or the access points, including OFDMA capability, MIMO capability, channel capability, etc. The optimization decision is used to select where client devices should connect, and optimization factors may include individual device throughput, joint load throughput (system capacity), fairness, etc.

Described herein are techniques for performing cell reselection in a wireless transmit/receive unit (WTRU). The method includes receiving a radio network terminal identifier (RNTI) from a first cell, transitioning from a connected state, performing cell reselection and to select a second cell different than the first cell, initiating resumption of communication by transmitting the RNTI to the second cell and resuming communications based on the transmitted RNTI.

A method performed by a connectivity-related network entity is provided. The method includes: receiving, from a Packet Data Network (PDN) gateway and a Serving Gateway (SGW), a Short Message Service (SMS) message to be sent in a downlink; determining to use a control plane only, out of the control plane and a user plane, for transferring the SMS message; transmitting a trigger message to a user equipment to initiate establishment of connectivity with the user equipment via the control plane only and not via the user plane, wherein the user equipment starts a timer when the establishment of the control plane connectivity is initiated; receiving a response message from the user equipment; encapsulating the SMS message in a security protected Non-Access Stratum (NAS) message; and transmitting the security protected NAS message to the user equipment, in receipt of which the user equipment stops the timer.

The present disclosure relates to service packet transmission methods. In one example method, a target user plane network element receives a first uplink service packet from a source user plane, where the first uplink service packet is an uplink service packet received by the source user plane after receiving a second uplink service packet, and the second uplink service packet is the last uplink service packet from the source user plane to a source application server. The target user plane network element receives first indication information, used to indicate that sending of the first uplink service packet by the source user plane network element ends, from the source user plane network element. The target user plane network element sends, to a target AS after the first uplink service packet is sent, an uplink service packet that is from an access network device to the target user plane network element.
