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.
Claims20
A method of negotiating a release version, performed by a network node, the method comprising steps of:
- receiving from an initiating node, a session request comprising identification of a plurality of releases supported by said initiating node;
- determining which of said plurality of releases are also supported by said network node;
- selecting a preferred release from said also supported releases;
- and
- transmitting to said initiating node, identification of said selected release.

A method of negotiating a release version, performed by an initiating network node, the method comprising steps of:
- sending a session request comprising identification of a plurality of releases supported by said initiating node, to a receiving node;
- and
- receiving from said receiving node, identification of a release selected by said receiving node, also supported by said receiving node from said plurality of releases.
A tangible and non-transitory machine-readable storage medium encoded with instructions for execution by a network node, the tangible and non-transitory machine-readable storage medium comprising:
- instructions for receiving at said network node, from an initiating node, a session request comprising identification of a plurality of releases supported by said initiating node;
- instructions for determining which of said plurality of releases are also supported by said network node;
- instructions for selecting a preferred release from said also supported releases;
- and
- instructions for transmitting to said initiating node, said selected release.
