1. A method operational at a wireless communication device for wireless communication with a network, the method comprising:establishing a radio communication connection with a first radio access node (RAN);
transmitting user plane data to the first RAN using control plane signaling;
determining that the wireless communication device is experiencing radio link failure (RLF) with the first RAN and that the radio communication connection should be reestablished with a second RAN;
obtaining a user equipment message authentication code (MACUE) based at least in part on one or more bits of a non-access stratum (NAS) COUNT value maintained at the wireless communication device;
sending a reestablishment message to the second RAN, wherein the reestablishment message comprises parameters used by a core network node communicatively coupled to the second RAN to authenticate the wireless communication device; and
reestablishing the radio communication connection with the second RAN, wherein the parameters comprise the MACUE.
