1. A method for updating a roaming list with a communication entity, comprising:
- storing a roaming list of a format among multiple possible formats;
receiving from the communication entity a capability request;
responding to the capability request by indicating support for the roaming list;
receiving from said communication entity a configuration request for identifying said format of said roaming list, wherein the configuration request is separate from the capability request;
sending configuration information of said format to said communication entity, wherein the configuration information is descriptive of at least one characteristic of the roaming list; and
updating said roaming list if said format is supported by said communication entity.

Abstract
Method and apparatus for updating roaming lists. An error handling message is provided when the roaming list protocols within the elements of a system are not compatible. A roaming list format identifier is provided to the remote user identifying the protocol version supported by the network. The roaming list format identifier acts to either request an old version of the protocol or request the current stored format at the remote user. In one embodiment, the old version is the Preferred Roaming List, and the new version is the Extended Preferred Roaming List.
