    摘要： Aspects of the present disclosure provide apparatus and methods to reduce the time taken to perform multiple packet data network (PDN) context transfers during inter-radio access technology (IRAT) scenarios. Certain aspects provide methods and apparatus for wireless communication by a device capable of communicating in at least a first and second RAT networks. The device may have multiple PDN contexts established in the first RAT network. As part of a transition to the second RAT network, the mobile device may transmit a single signaling message that indicates at least two of the PDN contexts to be transferred. In some aspects, the single signaling message may also indicate a new PDN context to be established as part of the transition.
