Method and apparatus for radio link failure recovery in a wireless communications network
In a wireless network, for example, an LTE network, the context information relating to a mobile terminal UE is transmitted to a plurality of network nodes eNB 2, 3 and 4 from a source network node, eNB 1. One of the eNB 2 is a handover target node and also reserves resources for the UE in anticipation of receiving it after handover. The other eNBs 3 and 4 do not reserve resources. In the event of radio link failure, the UE may attach to one of the designated eNBs 3 and 4 that have not reserved resources, but that do recognize the UE because they have received its context. The method reduces the likelihood of the UE needing to go via the time consuming IDLE state while only reserving resources at a handover target eNB. |
