Abstract:
Methods and systems for re-establishing radio contact include, for example, a method for performing a wireless handoff for user equipment (UE) as the UE performs a handoff from a source extended Node-B (e-NB) to a target e-NB is disclosed. The method includes detecting a radio link failure (RLF) between the UE and the source e-NB by the UE, and maintaining an active communication service at a service layer of the UE after detecting the RLF and as the UE performs the handoff from the source e-NB to the target e-NB such that the communication service remains continuously active during the handoff, the communication service supporting a first communication between the UE and a third party.
