More Information
Summary:Embodiments herein provide a method for handling a RRC re-establishment procedure in a wireless network by a network apparatus. The method includes detecting a radio link failure at a UE in the wireless network; receiving an RRC re-establishment request message from the UE; sending a downlink RRC re-establishment message and facilitating the allocation of an uplink grant to the UE; receiving a RRC re-establishment complete message from the UE on the allocated uplink grant resource. The method can be used to improve RRC re-establishment procedure completion time by efficient provisions of UL grant allocation to send a RRC Re-EstablishmentComplete. Using the disclosed method, there is drastic signaling reduction/resource wastage during the RRE procedure, thereby resulting in power saving of the UE and the network apparatus.
