Attention (AT) command for offloading packet data network connections

摘要

Systems, apparatus, and processes for obtaining data for a particular PDN connection in a cellular network are described herein. The UE executes one or more applications that utilize one or more PDN connections of the cellular network. The TE generates an AT command for the MT, the AT command is data for a specific PDN connection that can be offloaded from the cellular network to the non-cellular network, assistance data for determining traffic offload, and cellular signal measurements Including requests. The TE receives an AT command response that includes data about whether a particular PDN connection can be offloaded, offload assistance data, and / or cellular network measurement data corresponding to the AT command. The TE may receive an unsolicited result code if the PDN connection's offload capability changes, offload assistance data changes, or if the cellular signal measurement meets the offload assistance criteria.
