Abstract:
1. A method for mitigating local cell identifier collision by a base station, comprising: receiving, at a first base station from a user device, a reconnection message including a user device identifier and a local cell identifier; determining, at the first base station, a potential local cell identifier collision between the first base station and a second base station based on the user device identifier and the local cell identifier; receiving, following the reconnection message, a connection establishment request indicating a presence of a Radio Link Failure (RLF) report; retrieving, in response to determining the potential local cell identifier collision and in response to receiving the connection establishment request, a global cell identifier from the RLF report; confirming the potential local cell identifier collision based on a mismatch between the global cell identifier of the RLF report and a global cell identifier associated with the first base station; and modifying or causing to be modified, by the first base station, one or more communication parameters of the first base station or the second base station in response to the confirmed potential local cell identifier collision.
