    摘要: A re-registration authorization is attached to a registration request or data packet sent from a mobile node roaming on a foreign network. The mobile node requests registration with its home network in order to maintain communication with the Internet and maintain identification of the mobile node by its individual home address. Such registration has a limited lifetime, and the re-registration authorization attached to the registration request or other data packet authorizes an intermediate communication entity in the foreign network to re-register the mobile node, on behalf of the mobile node, with the mobile node's home network, if the communication traffic of the mobile node indicates that the mobile node is still roaming on the foreign network. The rate of error is reduced by significantly reducing the amount of transmissions sent from the mobile node, and power consumption of the typically battery-powered mobile unit is reduced, as well.

    摘要: A method for routing data packets to a mobile node in a communication system which includes at least a first subnetwork of a first type supporting a first IP version and a second subnetwork of a second type supporting a second IP version. The mobile node is provided with a set of protocol stacks for handling data packets at least according to the first and the second IP version and with a home address at least according to the first and the second IP version. The home agent intercepts at least data packets addressed to the mobile node's home address according to the first or the second IP version and for encapsulating a data packet addressed to the mobile node in a packet according to the IP version of the foreign network to which the mobile node is attached, for routing the data packet to the mobile node.

    摘要: An arrangement for providing IP mobility for a mobile station (MS) provides a care-of-address (COA) for routing data packets when the MS is away from home. In one embodiment, the arrangement includes support nodes, called gateway GPRS support nodes (GGSN) or serving GPRS gateway support nodes (SGSN), and a foreign agent (FA) having an IP address. In order to save IP addresses and radio resources, the FA is integrated into one of the support nodes (e.g., the SGSN), and the IP address of, or an IP address provided by the FA is also used as the MS COA.
