Method to improve reestablishment success rate in LTE system-at source ENB during ping pongs

A method to perform successful RRC reestablishment across eNB seams in ping pong scenarios without data loss is described. The method includes, during a handover procedure of a UE from a source AP to a target AP, receiving, at the source AP, a reestablishment request from the UE. The reestablishment...

Zusammenfassung:A method to perform successful RRC reestablishment across eNB seams in ping pong scenarios without data loss is described. The method includes, during a handover procedure of a UE from a source AP to a target AP, receiving, at the source AP, a reestablishment request from the UE. The reestablishment request includes a temporary identity assigned by the target AP for the UE. The method also includes determining a UE context based on the temporary identity assigned by the target AP and performing a reestablishment procedure between the source AP and the UE. Apparatus and computer readable media are also described.
