1. A mobile station configured for providing information about a roaming list, comprising:
- means for storing the roaming list, wherein a format of the roaming list is selected from among multiple possible formats, and wherein the multiple possible formats comprise an older format and a newer format;
means for receiving a configuration request message from a network infrastructure element, wherein the configuration request message comprises either a request for configuration information for the older format of the roaming list or a request for configuration information for whichever format of the roaming list is stored by the mobile station; and
means for sending a configuration response message to the network infrastructure element.

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.
