Methods and apparatus allow a communications network and a mobile terminal to dynamically negotiate for a preferred location area registration scheme, a preferred communications protocol and/or a preferred communications standard. As a result, differently configured equipment can coexist within a single network, and advanced schemes, protocols and/or standards can be gradually introduced into implemented systems. According to an exemplary embodiment, a mobile terminal and a network negotiate, upon an initial registration of the terminal with the network, for a location area registration scheme to be used for tracking terminal movement. In the embodiment, available location area registration schemes are numbered according to complexity level, and numbers corresponding to schemes which the terminal and the network can implement are used to negotiate a preferred, mutually acceptable scheme. When the terminal enters an area in which the prevailing scheme is no longer supported, or where the prevailing scheme is no longer the best available scheme, the terminal and the network renegotiate for a new best, mutually agreeable scheme.
