A method, system, and device provide for establishing IP level connectivity between an L-2 dormant mobile node (MN) and an IP cellular network, such as a Mobile IPv4, IPv6, of hybrid Mobile IPv4/IPv6 cellular network. An L-2 dormant mobile node detects a condition requiring enablement of IP level connection to execute the IP level procedures. The L-2 dormant mobile node, in response to detecting the condition, sends an initiation signal to the radio access network. The radio access network, in response to the initiation signal, initiates a radio bearer setup to facilitate executing of the IP level procedures. The radio bearer, in one approach, is a default radio bearer associated with the mobile node.
