Aspects of the subject disclosure may include, for example, detecting at a mobile device a communication failure of a data connection between the mobile device and a source core network of a plurality of core networks available to the mobile device, the mobile device communicating with a respective core network of the plurality of core networks through a radio access network, selecting a destination core network of the plurality of core networks, and handing off the data connection from the source core network to the destination core network.

A telecommunication network associated with a wireless telecommunication provider can be configured to dynamically switch the primary cell (PCell) used by user equipment (UE) for carrier aggregation (CA) in 5G cellular networks. Instead of remaining anchored to an initially selected PCell, a different PCell may be dynamically selected based on different network conditions. The network conditions may include network congestion, network capacity, uplink speed, location of the UE, an activity of the UE (e.g., is the UE uploading or planning to upload data), and the like. As an example, the PCell may be selected from an n41 (2.5 GHz) cell and an n71 (600 MHz) cell. When the UE is close to the n41 cell, the n41 cell may be selected. When the UE is moving away from the cell center and toward the cell edge, the PCell may be switched from the n41 cell to the n71 cell.

A method for a user equipment maintaining a first set of configuration parameters includes: measuring strength of signals transmitted by a first base station, measuring strength of signal transmitted by at least one of a set of neighbor base stations operating in unlicensed spectrum, determining a second set of configuration parameters corresponding to the cellular network for a second base station in a set of neighbor base stations, by retrieving said set of configuration parameter from said second base station, considering the second base station for cell re-selection when: the measured signal strength for the second base station is higher than said measured signal strength of first base station, and said determined second set of configuration parameters corresponds to said first set of configuration parameters, and carrying out a cell selection to said second base station when these conditions are met.

Systems and methods for facilitating handover reduction in satellite systems are disclosed. A system may include a processor and a memory storing instructions, which when executed by the processor, may cause the processor to detect a user terminal that is selected for a handover procedure. The handover procedure may facilitate a switch from a source beam to a target beam. Based on input data, the processor may evaluate an ideal time value pertaining to a pre-defined time instance at which a scheduled handover is to be performed. The scheduled handover may correspond to at least one of a scheduled change in operating frequency within same beam or a scheduled feeder link handover due to a change in gateway communicating with the satellite. Based on the evaluation and the input data, the processor may estimate an optimized time value that pertains to an optimized time instance associated with an expected handover reduction.

A method of performing cell reselection by a wireless communications device comprises measuring a signal strength of radio signals received from a serving cell, determining whether the signal strength of the signals received from the serving cell is lower than a first predetermined signal strength threshold, if the signal strength is lower than the first predetermined signal strength threshold measuring a signal strength of a neighbor cell operating on the same frequency as the serving cell to generate signal strength measurements at a first rate, and in accordance with the signal strength measurements of the neighbor cell generated at the first rate determining whether to reselect to the neighbor cell.

Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for a primary secondary cell (PSCell) change failure. In example embodiments, a master network device receives, from a source secondary network device, a first request for a change of a terminal device from the source secondary network device to a target secondary network device. The master network device receives, from the source secondary network device, an identification of a source PSCell operated by the source secondary network device and serving the terminal device prior to the first request. The master network device further receives, from the terminal device, an indication of a radio link failure of the terminal device in a PSCell and transmits the indication of the radio link failure to the source secondary network device along with the identification of the source PSCell.
