Abstract
A method of managing evolved universal mobile telecommunication system terrestrial radio access network (E-UTRAN) capability of a user equipment (UE) is provided that includes switching from a first radio access technology (RAT) to a second RAT if the first RAT fails to provide circuit switched (CS) services to the UE, the first RAT and the second RAT being associated with a first public landline mobile network (PLMN). The UE establishes a CS call session with the second RAT. In the meanwhile, the UE receives a network handover command to move to a second PLMN. The UE may also perform a movement from the first PLMN to the second PLMN and connect with a third RAT associated with the second PLMN to continue the CS call session. The UE enables the E-UTRAN capability after moving to the second PLMN to connect with a fourth RAT available in the second PLMN.
