METHODS AND SYSTEMS FOR ENSURING CONTINUITY OF SERVICES ON HANDOVER FROM WI-FI TO CELLULAR NETWORKS

Methods and systems for ensuring continuity of services on handover from Wi-Fi to cellular networks are disclosed. Embodiments of the disclosure allow a UE to seamlessly engage in a call during a handover, which is triggered on detecting that QoS of the call is less than a threshold within a coverage area of the Wi-Fi. The continuity of the call is ensured by triggering a handover from Wi-Fi to LTE and preventing/reducing handover from Wi-Fi to NR. The UE avails calling services using LTE and data services using NR, by enabling NSA mode. The UE is allowed to avail calling services seamlessly by initiating a handover of the calling services from Wi-Fi to LTE and avail data services seamlessly by initiating a handover of the data services from Wi-Fi to NR. The handover from Wi-Fi to LTE/NR is initiated if QoS of the calling/data services is less than a threshold in Wi-Fi coverage area.

COMMUNICATION METHOD AND APPARATUS
20230092054 · 2023-03-23 · ·

A communication method and apparatus are provided. The method includes: A source network device generates and sends a first message, where the first message is for handing over a terminal device from the source network device to a target network device, the first message includes first indication information, and the first indication information indicates to perform a random access-free process and/or a handover complete message-free process in a handover process. In this way, if cell jump occurs in a source cell, the terminal device may not perform a random access process and/or not send a handover complete message in a process of handover from the source cell to a target cell. This avoids uplink congestion of the target cell caused by simultaneous handover of a plurality of UEs to the target cell, effectively reduces signaling overheads, and improves network performance of a target base station.

BEAM-SPECIFIC KEY PERFORMANCE INDICATOR INDICATION FOR SERVING NODE SELECTION

Methods, systems, and devices for wireless communications are described. For example, a communication device may receive control signaling (e.g., a broadcasted control signal) from another communication device. The control signaling may indicate beam information for one or more beams of a set of beams. The one or more beams may correspond to the serving cell or one or more neighboring cells. The beam information may include one or more metrics associated with each of the one or more beams. As such, the communication device may determine that a metric associated with each of the one or more beams satisfies a threshold, select the beam, and communicate using the selected beam. In some other examples, the beam-specific information may include beam measurement offsets for one or more beams. In such examples, the communication device may select a beam based on the beam measurement offsets and perform communications using the selected beam.
