A media-independent handover (MIH) environment supports a MIH function that uses a mapping table to communicate with other MIH functions using a MIH transport protocol. The MIH function updates the mapping table upon receipt of a message having fields to invoke an operation. The operation can update an existing mapping or delete a mapping. The operation also can update a lifetime value for a mapping for a particular address. The mapping table includes mappings. A mapping includes a MIH function identifier, a list of transport addresses, and a lifetime value.
