Abstract
Examples pertaining to a mobility registration update (MRU) required after rejection in another radio access technology (RAT) in mobile communications are described. A user equipment (UE), after being registered in a first network, switches from the first network to camp on a second network different from the first network. The UE then switches back to camp on the first network. Next, the UE performs a mobility registration type of procedure in the first network to restore at least one parameter which was initially stored in the UE when registered in the first network before switching to the second network and later discarded during connection to the second network.
