Addressing techniques for use in an internet protocol-based multimedia mobile network
First Claim
1. A method for use in an Internet Protocol (IP) based communications system, the method comprising the steps of:
- assigning a temporary location IP address to a mobile user station in the communications system, the address being a combination of an identifier of the mobile user station and an identifier of a network node in the communications system with which the mobile user station is currently associated; and
transferring packets to and from the mobile user station in accordance with the temporary location IP address.

Abstract
In an IP addressing aspect of the invention, a method for use in an Internet Protocol (IP) based communications system, comprises the steps of: (i) assigning a temporary location IP address (e.g., LIPA) to a mobile user station in the communications system, the address being a combination of an identifier of the mobile user station (e.g., MID) and an identifier of a network node in the communications system with which the mobile user station is currently associated (e.g., RID); and transferring packets to and from the mobile user station in accordance with the temporary location IP address. The method may further comprise the step of changing the temporary location IP address assigned to the mobile user station when the station becomes associated with another network node of the communications system, the changed address being a combination of the identifier of the mobile user station and an identifier of the new network node. The method may further comprise the step of assigning a location IP address to a network node in the communications system, the address being a combination of an identifier of the network node and a common identifier of mobile user stations in the communications system.

13. In an Internet Protocol (IP) based communications system including a plurality of network nodes and a plurality of mobile user stations, a method for use in directing packets in the communications system, comprising the steps of:
-
assigning a unique location IP address to each network node in the communications system;
assigning a unique location IP address to each mobile user station in the communications system, the unique location IP address of each mobile user station changing as a function of the network node with which the mobile user station is currently associated; and
transferring packets to and from the network nodes and the mobile user stations in accordance with the unique location IP address. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
