Abstract: Embodiments of the invention provide an improved major release negotiation mechanism between an initiating node and a receiving node during Diameter session establishment in a 3GPP network.

Abstract: Embodiments are disclosed that enable a device such as a policy and charging rules function (PCRF) node to operate with other nodes in a long term evolution (LTE) network that are operating at different respective major-minor release combinations of the 3rd Generation Partnership Project (3GPP) standards. Some embodiments enable such a device to operate with another node at a given major-minor release combination of the 3GPP standards with respect to an existing session being managed by the device and at another major-minor release combination of the 3GPP standards when a new session is established by the device. Advantageously, such embodiments mitigate the risk of adversely affecting the existing session after a minor release upgrade of the node associated with the session is performed.
