Abstract: Techniques are described for dynamically determining the flow of screens to be presented in a user interface (UI) of an application executing on a computing device, based at least partly on a detected presence of a user device (e.g., a portable computing device) in a particular geographic area. Area designation data is transmitted to, and stored on, a user device. The area designation data can describe a geofenced area and/or beacon signals. In response to determining that the user device is in the geographic area indicated by the area designation data, the user device may transmit an alert signal that causes an interface flow to be dynamically determined and executed for an application executing on the computing device that is separate from the user device.

Abstract: Locations of cells of a communication network can be estimated, determined, and validated. Cell location component (CLC) can analyze timing advance (TA) measurement data and/or location data associated with devices associated with a base station associated with one or more cells. CLC can estimate a first location of the base station, based on the TA measurement data and/or location data, to facilitate estimating the location of an associated cell. CLC can validate the estimated cell location or recorded cell location of the cell (recorded in a cell location pool) based on analysis of estimated cell location, recorded cell location, TA measurement data, and/or location data, and, based on the validation, can tag the cell location determination as accurate, acceptable, bad, or uncertain. CLC can request additional monitoring of a cell location determination tagged as uncertain, or investigation of a cell location determination tagged as bad.

Abstract: A method for a re-authentication of user equipment (UE), by at least a portion of a core network (CN), for steering of roaming (SoR) data delivery, includes receiving, through next generation radio access network (NG-RAN) and/or 5G system (5GS), a subscriber data management (SDM) data request for a UE. The method includes determining that re-authentication of the UE be requested. The method includes encoding a response for transmission to the UE responsive to the SDM data request. Determining that re-authentication be requested can include determining that SoR data is being sent to the UE.

Abstract: A method and system for providing a cooperative spectrum sharing model that jointly optimizes primary user equipment parameters for improved frequency agility and performance while mitigating mutual interference between the primary user equipment and secondary user equipment. Spectrum sensing is implemented to form a power spectral estimate of the electromagnetic environment (EME) and apply multi-objective optimization to adjust the operational parameters of the primary user equipment to mitigate interference.

Abstract: A system and method may improve latency for user equipment (UE) registration in cellular networks. UE registration may retrieve the UE's configuration and subscription data locally rather than from a network or cloud-based unified data management (UDM) entity that manages a unified data repository (UDR). For example, the UE may send a unique identification (e.g., a UE ID) for the UE to a registering entity of a cellular network system. The UE ID may then be used to identify a UE Group Identification for the UE at the UDM. The UE Group Identification may be a pointer to the locally-stored configuration and subscription data for the UE. The entity requesting registration may then use the pointer to retrieve the configuration and subscription data locally rather than a remote entity such as the UDM.

Abstract: Systems and methods of signaling RDS and PS Data Off in a UE and to a network are described. A UE includes TE and a MT. The TE determines whether RDS and PSDO are to be used for a PDN connection, and generates an AT command for communication to the MT to indicate an RDS status and a PSDO status of the PDN connection. The MT indicates to the network, based on the AT command, the RDS status and PSDO status of the PDN connection at the ME. The AT command enables the TE and allows the ME to communicate support for, and the status of RDS and PSDO, to the MT and enables usage, testing and status reporting of the features.

Abstract: A method and system for content filtering. A network repository function unit registers a session management function unit. The session management function unit initiates a session in response to a session request from a user equipment. The session management function unit accesses a subscriber profile stored by a data management unit, and the subscriber profile includes one or more content filtering settings. In response to the session being established, the session management function unit is configured to determine data packets for the user equipment to be filtered based on the one or more content filtering settings. Absent triggering an instruction to be sent via a Gx interface, an access and mobility management function (AMF) unit is configured to select the session management function unit in compliance with the one or more content filtering settings for filtering the data packets for the user equipment.

Abstract: An information verification method and a related device. The method includes: receiving, by a first profile server, a remote profile management request sent by a remote profile management server, where the remote profile management request includes a first profile owner identifier; obtaining a second profile owner identifier in profile information; determining whether the first profile owner identifier is the same as the second profile owner identifier; and sending a remote profile management command to user equipment when the first profile owner identifier is the same as the second profile owner identifier. In this way, a loss caused to an operator or a profile owner due to a user's access to an invalid network or random profile unlocking is avoided, network security is improved, and waste of network resources is reduced.

At a user equipment side, the method includes: receiving a group identifier and a paging indicator monitoring occasion transmitted from a base station; monitoring a paging indicator at the paging indicator monitoring occasion; starting to monitor paging control information, when it is monitored that the paging indicator contains the group identifier.

Abstract: A RAN location server function (e.g. for 5G New Radio), referred to as Location Management Component (LMC), may be included in a gNB and connected to a gNB Central Unit (gNB-CU). The gNB-CU may receive a location request for a UE (e.g. from an AMF) and may initiate a location session for the UE, including selecting an LMC for the location session. The gNB-CU may handover the UE to a new serving gNB during the location session. The LMC for the location session may then remain unchanged after the handover or may be changed to a new LMC to suit the new serving gNB. The location session may then continue using the original LMC if not changed or the new LMC if changed.

The method includes receiving a signal from a tracking device in an environment of the first computing device, the signal including an identifier for the tracking device in the environment of the first computing device. The method includes determining that the tracking device in the environment of the first computing device is the tracking device of the request to locate the tracking device by comparing the identifier for the tracking device received from the tracking system server and the identifier for the tracking device in the environment of the first computing device. The method includes providing, to the tracking system server, the location associated with the tracking device and the identifier for the tracking device.

Abstract: A system for providing locations of emergency callers receives call data related to emergency calls received at a public safety answering point (PSAP) and a supplemental data signal that includes a location of an emergency. A signal correlation engine determines whether the supplemental data signal corresponds to one of the emergency calls received at the PSAP. A web server provides a user interface that includes a map and a supplemental signal indicator corresponding to the supplemental data signal. The supplemental signal indicator is positioned on the map at the location of the emergency, and the supplemental signal indicator has a visual characteristic indicating whether or not the supplemental data signal corresponds to an emergency call received at the PSAP.
