Managing mobility events in simultaneous rat mode user equipment

摘要

Mobility management is described for simultaneous, multiple radio access technology (RAT) user equipments (UEs). When the UE detects a mobility event that would trigger transfer of a communication service from a first RAT to a second RAT, the UE determines whether there is an existing connection to a base station of the second RAT and uses cached measurement information related to this base station to influence or weight how the transfer is performed/handled/managed.

主权项

1. A method of wireless communication, comprising:
detecting, at a user equipment (UE), a mobility event triggering transfer of first communication services at the UE from a first radio access technology (RAT) to a second RAT, wherein the UE is configured for simultaneous communication with the first and second RATs; receiving, by the UE, mobility transfer information from a second base station of the first RAT related to the transfer, wherein the mobility transfer information includes information for measurement of a plurality of neighboring second RAT base stations; and receiving, by the UE, second communication services from a first base station of the second RAT when the UE is in an idle state with the second base station of the first RAT related to the first communication services; and modifying, by the UE, evaluation of reselection criteria for the selection of the first base station of the second RAT for the first communication services that are originally handled by the second base station of the first RAT without interruption of the receiving the second communication services from the first base station of the second RAT, wherein the modifying comprises evaluating the reselection criteria based at least in part on cached measurement information for the first base station.
