MECHANISM TO AVOID PING PONG DURING INTER RADIO ACCESS TECHNOLOGY REDIRECTION FAILURE

摘要

The present disclosure provides a method, apparatus, and computer-readable medium that is able to avoid ping pong mobility when a redirection procedure fails. The apparatus may attempt to perform a redirection procedure from a first RAT to a target frequency of a second RAT. The apparatus may receive a redirection failure notification indicating that the target frequency of the second RAT is unavailable. The apparatus may refrain from initiating a reselection procedure to the target frequency of the second RAT for a predetermined time period. The apparatus may deprioritize the target frequency of the second RAT for the predetermined time period when the target frequency of the second RAT is unavailable and is present in an SIB received from the neighbor cell. The apparatus may generate a list of banned frequencies that includes the target frequency of the second RAT when the target frequency of the second RAT is unavailable.
