Offloadability of PDN connection for LTE-WLAN interworking control and management

Methods for LTE-WLAN interworking control and management are proposed. In one novel aspect, terminal equipment (TE) can use an AT command to query the WLAN offloadability of a packet data network (PDN) connection. A mobile termination (MT) can store the WLAN offloadability indication in its memory and return the value to TE upon receiving the AT command. In one example, a new field can be added to an existing AT command.
