Abstract
Systems and methods are described for exchanging network protocol configuration option (PCO) parameters for a mobile device in a communications network (IP) address to enable communication with the mobile device with untrusted WLAN access. In one embodiment, the PCO is passed in a first interface from mobile device to first gateway and passed as is over a second interface to a packet gateway. In a second embodiment, the first interface carries information used in PCO in configuration options/Information elements, such as configuration option in IKE in case of ePDG. The serving gateway, such as an ePDG, creates PCO and extracts the information from first interface and then sends PCO over the second interface. In the response path the PCO response is used to fill in information that is sent in the first interface.
