Systems, devices, and configurations to implement trusted connections within wireless networks and associated devices and systems are generally disclosed herein. In some examples, a wireless local area network (WLAN) may be attached to a 3GPP evolved packet core (EPC) as a trusted access network, without use of an evolved packet data gateway (ePDG) and overhead from related tunneling and encryption. Information to create the trusted attachment between a mobile device and a WLAN may be exchanged using Access Network Query Protocol (ANQP) extensions defined by IEEE standard 802.11u-2011, or using other protocols or standards such as DHCP or EAP. A trusted WLAN container with defined data structure fields may be transferred in the ANQP elements to exchange information used in the establishment and operation of the trusted attachment.
