Claim Text:
1. A method of employing an encoding scheme for media independent handover of a mobile node that is connected to a first access network during handover to a second heterogeneous access network, comprising: a node receiving media independent handover protocol messages transmitted between a mobile node connected to the first access network and a media independent handover entity within a network node in said second heterogeneous network, wherein said first access network is one of an I.E.E.E. 802 network and a non-I.E.E.E. 802 network and said heterogeneous second access network is the other of an I.E.E.E. 802 network and a non-I.E.E.E. 802 network, said media independent handover protocol messages having a field identifying a variable-length data type without a length value being included within said field identifying said variable-length data type, said node determining length based on said variable-length data type identified in said field by selecting an encoding rule that corresponds to said identified variable-length data type from a set of a plurality of different encoding rules that each correspond to different variable-length data types, and wherein said set of encoding rules that each correspond to different variable-length data types include encoding rules that correspond to data type categories, including general data types that are not derived from other data types and derived data types that are derived from said general data types, wherein an encoding rule corresponding to a derived data type is the same as the encoding rule corresponding to the basic data type from which the derived data type is derived.
