Abstract
Example embodiments presented herein are directed towards determining a Proxy Mobile Internet Protocol version 6 (PMIPv6) control plane used by a network node peer in an Internet Protocol version 4 (IPv4) transport network. The example embodiments provide a mechanism in PMIP protocol stack, to allow a Mobility Access Gateway/Local Mobility Anchor (MAG/LMA) node such as SGW (which may be supporting both PMIP draft and PMIP RFC) to decide which PMIP protocol stack shall be used to communicate to the peer node, i.e. LMA/MAG.
Claims30
A method in a first network peer node for determining a Proxy Mobile Internet Protocol version 6 (PMIPv6) control plane used by a second network peer node, the first and second network peer nodes being in an Internet Protocol version 4 (IPv4) transport network, the method comprising:
- sending, to the second network peer node, at least one communication message in at least one control plane format;
- receiving at least one communication response with respect to the at least one communication message;
- and
- determining a version of the PMIPv6 control plane which is utilized by the second network peer node based on the at least one communication response.
A first network peer node for determining a Proxy Mobile Internet Protocol version 6 (PMIPv6) control plane used by a second network peer node, the first and second network peer nodes being in an Internet Protocol version 4 (IPv4) transport network, the first network peer node comprising:
- transmitting circuitry operable to send, to the second network peer node, at least one communication message in at least one control plane format;
- receiving circuitry operable to receive at least one communication response with respect to the at least one communication message;
- and
- processing circuitry configured to determine a version of the PMIPv6 control plane which is utilized by the second network peer node based on the at least one communication response.
