Attention (AT) command for packet data network connection offload

摘要

Described herein are systems, devices, and processes for obtaining data for a particular PDN connection in a cellular network. The UE executes one or more applications using one or more PDN connections of the cellular network. The TE includes an AT for the MT, including a request for data for a particular PDN connection that can be offloaded from the cellular network to a non-cellular network, a request for assistance data to determine offload of traffic, and a request for cellular signal measurements. Command. The TE receives an AT command response corresponding to the AT command and the AT command response includes data on whether the particular PDN connection can be offloaded, offload support data and / or cellular network measurement data. The TE may receive an undesired result code when the offload capability of the PDN connection is changed, the offload support data is changed, or the cellular signal measurements meet the offload support criteria.
