Cell Selection Optimization During RRC Reestablishment - A simplified explanation of the abstract

This abstract first appeared for US patent application 17448788 titled 'Cell Selection Optimization During RRC Reestablishment

Simplified Explanation

The abstract describes a patent application for a user equipment (UE) that can receive a mobility configuration from a source cell of a network. If a radio link failure (RLF) event occurs on the source cell, the UE will search for a primary cell (PCell) only on frequencies associated with the mobility measurement object to reestablish a radio resource control (RRC) connection.

  • The patent application is for a technology that allows a UE to reestablish an RRC connection after a radio link failure event.
  • The UE receives a mobility configuration from a source cell, which includes at least one mobility measurement object.
  • If an RLF event occurs on the source cell, the UE will search for a PCell only on frequencies associated with the mobility measurement object.
  • The UE will then reestablish the RRC connection with the PCell.

Potential Applications

  • This technology can be applied in cellular networks to improve the reliability and stability of connections between user equipment and network cells.
  • It can be used in various industries that rely on mobile communication, such as telecommunications, transportation, and public safety.

Problems Solved

  • The technology solves the problem of radio link failures, which can lead to dropped calls or interrupted data connections.
  • By searching for a PCell only on frequencies associated with the mobility measurement object, the technology reduces the time and resources required to reestablish the RRC connection.

Benefits

  • The technology improves the user experience by minimizing the impact of radio link failures and reducing connection downtime.
  • It optimizes network resources by efficiently searching for a PCell on specific frequencies, rather than scanning all available frequencies.
  • The technology enhances the overall reliability and stability of cellular networks, leading to improved communication services.


Original Abstract Submitted

A user equipment (UE) is configured to receive a mobility configuration from a source cell of a network, wherein the mobility configuration includes at least one mobility measurement object, determine that a radio link failure (RLF) event has occurred on the source cell, searching for a primary cell (PCell) only on frequencies associated with the at least one mobility measurement object to reestablish a radio resource control (RRC) connection and reestablish the RRC connection with the PCell.
