摘要:
In a method for radio link failure (RLF) recovery in a wireless communications network, a timer T sets a predetermined time period from a command to a mobile terminal UE to hand over to a new eNB. Resources are reserved at a target eNB 2. If the time period expires without the UE attaching to the target eNB 2, the source eNB requests other candidate eNBs 3 and 4 to reserve resources. Once the UE associates with the target eNB 2, the resources reserved at candidate eNBs 3 and 4 are released. If the UE associates with the target eNB 2 prior to expiry of the time period T, resources are not unnecessarily reserved at the candidate eNBs 3 and 4. If the UE associates with one of the candidate eNB 3 instead of the target eNB 2, resources have already been reserved, enabling RLF recovery to be implemented without the UE going via LTE_IDLE, in an LTE arrangement.
