Policies to enable serving untrusted services on alternative (non-3GPP) and untrusted access networks in EPS

The popularity of mobile Internet is driving the Mobile world towards untrusted services while increasing Mobile Data volumes encourage adoption of untrusted access network for delivery of MNO services. This paper examines the emerging methods of utilizing untrusted access and facilitating untrusted third party services on either trusted or non-trusted access networks via existing and extended EPS facilities. These methods and policies should be better organized in an effort to manage a multi-access and open service environment, with heterogeneous access technologies and collaboration across business borders. This paper proposes enhancements to managing untrusted access, selection of best available access network and delivering sponsored services utilizing MNO's policies and authentication.
