Patent ID: 7877787

Claim:
An apparatus, comprising: a bootstrapping server function configured to transmit a first message to a home subscriber server, wherein the first message includes a timestamp parameter corresponding to a generic bootstrapping architecture user security settings stored in the bootstrapping server function and wherein the timestamp parameter corresponding to the generic bootstrapping architecture user security settings stored in the bootstrapping server function is compared with a timestamp parameter corresponding to a generic bootstrapping architecture user security settings stored in the home subscriber server wherein the bootstrapping server function is further configured to: receive from a home subscriber server, a second message excluding the generic bootstrapping architecture user security settings when the timestamp parameters of the generic bootstrapping architecture user security settings of the bootstrapping server function and the home subscriber server are equal, and receive, from the home subscriber server, the second message including the generic bootstrapping architecture user security settings and the corresponding timestamp parameter, and update the bootstrapping server function using the generic bootstrapping architecture user security settings and the timestamp, when the timestamp parameters of the generic bootstrapping architecture user security settings of the bootstrapping sever function and the home subscriber server are not equal, wherein the bootstrapping server function and the home subscriber server provide authentication for a wireless mobile network.
