Abstract: A system and method for providing wireless Internet protocol access is provided. A network entity may be coupled to both a second generation and a third generation network access node. The network entity may intercept a request from a mobile node and determine whether the mobile node desires services from the second or third generation network. The network entity may then establish the proper communication session based on the type of session requested by the mobile node. By employing the network entity, service providers can effectively migrate from the second generation network architecture to the third generation architecture with minimal or no loss of services for users. Also, employing such a network entity enables users to operate a bi-functional mobile node, such as one that requires both second and third generation network access.

Abstract: A method for storing and managing rekeying information for a secure communication system, as well as for carrying out a rekeying operation. Encryption key variables stored in memory (301) are represented by mnemonics (303) as part of an editable data base (302) that is arranged in the same order as communication unit key storage locations. Each communication unit (305) within the system is assigned to a specific group (304), while each group (304) is assigned to a particular editable data base (302).
