INITIATING RANDOM ACCESS IN A TARGET CELL IN A NON-TERRESTRIAL NETWORK - A simplified explanation of the abstract
This abstract first appeared for US patent application 17443154 titled 'INITIATING RANDOM ACCESS IN A TARGET CELL IN A NON-TERRESTRIAL NETWORK
Simplified Explanation
The patent application describes a method for dynamically controlling the initiation of random access in a non-terrestrial network. Here are the key points:
- When a user equipment (UE) detects an event that triggers a random access procedure in a target cell, it first monitors a control channel from the target cell during a specific time window.
- The UE waits for a control signal from the target cell during this monitoring window before initiating random access.
- The control signal contains a dynamic indication that identifies which UEs are allowed to initiate random access.
- UEs are not permitted to start contention-based random access in the target cell during the monitoring window unless they have received the control signal.
- This approach helps the target cell regulate the rate at which UEs initiate the random access procedure, which helps manage congestion in the target cell.
Potential applications of this technology:
- Non-terrestrial networks, such as satellite networks, can benefit from this method to manage congestion and control the rate of random access initiation.
- It can be applied in various communication systems where random access procedures are used, such as cellular networks, IoT networks, and wireless sensor networks.
Problems solved by this technology:
- Congestion management: By controlling the rate at which UEs initiate random access, the target cell can prevent congestion and ensure efficient network operation.
- Unregulated random access: Without the dynamic indication in the control signal, UEs may autonomously start random access, leading to increased contention and potential network issues.
Benefits of this technology:
- Improved network performance: By managing congestion, the target cell can provide better service quality to UEs and avoid network overload.
- Efficient resource utilization: Regulating the rate of random access initiation helps optimize the utilization of network resources.
- Enhanced user experience: By avoiding congestion, UEs can experience faster and more reliable connections in the target cell.
Original Abstract Submitted
Various aspects described herein relate to dynamically controlling a time when random access initiated in a target cell of a non-terrestrial network. For example, when a user equipment (UE) detects an event that triggers a random access procedure in the target cell, the UE may monitor a control channel from the target cell for a control signal during a target cell monitoring window prior to initiating random access in the target cell. For example, the control signal may include a dynamic indication to identify UEs allowed to initiate random access, whereby a UE is not permitted to autonomously start contention-based random access in the target cell during the target cell monitoring window unless the UE has received the control signal. In this way, the target cell may regulate a rate at which UEs initiate the RACH procedure in order to manage congestion in the target cell.
