  • Patent number: 12010559
    Abstract: Techniques for dynamically negotiating a service legal agreement (SLA) between a roaming device and a visited network (VN) in an identity federation. An identity profile provided to a user device by an identity provider (IDP) is accessed by the user device. The identity profile includes a first SLA criteria. An advertisement from the VN indicating one or more SLAs supported by the VN is received at the user device. The advertisement is received before the user device has associated with the VN. The IDP and the VN are part of a same identity federation. It is determined that the SLA supported by the VN satisfies the first SLA criteria. Upon that determination, an acceptance is transmitted by the user device to the VN, and the user device is associated with the VN.
