METHODS AND SYSTEMS FOR ENSURING CONTINUITY OF SERVICES ON HANDOVER FROM WI-FI TO CELLULAR NETWORKS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17966481 titled 'METHODS AND SYSTEMS FOR ENSURING CONTINUITY OF SERVICES ON HANDOVER FROM WI-FI TO CELLULAR NETWORKS
Simplified Explanation
The patent application describes methods and systems for ensuring uninterrupted services when switching from Wi-Fi to cellular networks. Here are the key points:
- The technology allows a user device (UE) to smoothly transition into a call during a handover process.
- The handover is triggered when the quality of service (QoS) for the call falls below a certain threshold within the Wi-Fi coverage area.
- To ensure continuity, the handover is specifically from Wi-Fi to LTE (Long-Term Evolution) and avoids or minimizes handover to NR (New Radio).
- The UE can use LTE for calling services and NR for data services by enabling Non-Standalone Access (NSA) mode.
- Seamless calling services are achieved by initiating a handover from Wi-Fi to LTE, while seamless data services are achieved by initiating a handover from Wi-Fi to NR.
- The decision to initiate the handover from Wi-Fi to LTE/NR is based on the QoS of the calling or data services being below a threshold within the Wi-Fi coverage area.
Potential applications of this technology:
- Mobile devices and smartphones that frequently switch between Wi-Fi and cellular networks.
- Voice over IP (VoIP) calls that need to maintain high-quality connections during handovers.
- Applications that require uninterrupted data services, such as video streaming or online gaming.
Problems solved by this technology:
- Ensures a smooth transition for users when switching from Wi-Fi to cellular networks, preventing call drops or service interruptions.
- Optimizes the use of LTE and NR networks based on the specific service requirements (calling or data) of the UE.
- Reduces the likelihood of unnecessary handovers to NR, which may not be as readily available or optimized for calling services.
Benefits of this technology:
- Seamless engagement in calls during handovers, providing a better user experience.
- Improved continuity of services by leveraging LTE for calling and NR for data.
- Efficient utilization of network resources by avoiding unnecessary handovers to NR.
Original Abstract Submitted
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.
