摘要： A method 900 of and apparatus for effecting a handoff from a first Internet Protocol (IP) connection 221 to a second IP connection 331 is disclosed. The method includes: communicating a packet data communication between a first station and a gateway (either acting as an application level gateway or as and endpoint for an SCTP tunnel) using the first IP connection and a first IP address for the first station, the gateway relaying the packet data communication with a second station; setting up the second IP connection with a second IP address for the first station, the first IP connection being a primary connection and the second IP connection being a secondary connection between the first station and the gateway, the first and the second IP connection existing concurrently; determining that the second IP connection should be the primary connection between the first station and the gateway; and changing the second IP connection to the primary connection by informing the gateway that the second IP address is the primary address using stream control transmission protocol (SCTP) messages, wherein the packet data communication is immediately switched over to the second IP connection.

摘要： A method 900 of and wireless communications unit 800 for effecting a handoff from a first Internet Protocol (IP) connection 221 to a second IP connection 331 for a time critical communication is disclosed. The method includes communicating 905 between a first wireless station 219 and a second station 331 using the first IP connection and a first IP address 223 for the first wireless station; setting up 907 the second IP connection with a second IP address for the first wireless station, the first IP connection being a primary connection and the second IP connection being a secondary connection, both existing concurrently; determining 915 that the second IP connection should be the primary connection; and changing 917 the second IP connection to the primary connection by informing the second station that the second IP address is the primary address using stream control transmission protocol (SCTP) messages, wherein the time critical communication is immediately switched over to the second IP connection.

摘要： A method and system are disclosed for changing the structure of one or more policies and/or the order of application of one or more policies to resolve conflicts among a set of policies using graph-theoretic techniques. Policies are used to govern the states of managed entities (e.g., resources and services). The set of states of the set of managed entities are represented as nodes of a graph. The output of the set of applicable policies governing all or part of the nodes is then used to control the transition between some or all nodes in the graph.
