Method of Enhanced Connection Recovery and Loss-less DATA Recovery |
摘要 |
An enhanced connection recovery upon lost RRC connection due to radio link failure (RLF) or handover failure (HOF) is proposed. A UE first establishes an RRC connection in a source cell in a mobile communication network. Later on, the UE detects a failure event and starts an RRC reestablishment procedure in a target cell to restore the RRC connection. In a first novel aspect, a fast NAS recovery process is applied to reduce the outage time in the target cell. In a second novel aspect, context fetching is used to reduce the outage time in the target cell. In a third novel aspect, a loss-less reestablishment procedure is proposed to reduce data loss during the connection recovery.
