US 2006/0140177 A1 · Method and device for setting a route for communication connection

Abstract

A method and a device set a route for a communication connection of a communication unit in a mobile network environment. When a communication unit connects to a routing network element it is determined by the routing network element whether the communication unit belongs to the same home network as the routing network element. Then, a selection for an address information to be sent to the communication unit is made. If it is determined that the communication unit belongs to the same home network as the routing network element, a first type of address information is selected. If it is determined that the communication unit belongs not to the same home network as the routing network element, a second type of address information is selected. The selected address information is sent from the routing network element to the communication unit, in which it is used for setting a route for the communication unit.

Dependent claims

A method of setting a route for a communication connection of a communication unit in a mobile network environment, the method comprising steps of:

connecting a communication unit to a routing network element;
determining, in the routing network element, whether the communication unit belongs to a home network of the routing network element;
selecting, if the communication unit belongs to the home network of the routing network element, a first type of address information, or selecting, if the communication unit does not belong to the home network of the routing network element, a second type of address information;
sending the first or second type of address information from the routing network element to the communication unit;
and
using the first or second type of address information received from the routing network element for setting a route for the communication unit.

A communication system usable in a mobile network environment comprising at least one routing network element and at least one communication unit, the system configured to set a route for a communication connection of a communication unit in the mobile network environment, wherein the routing network element is configured to

detect that the communication unit connects to the routing network element,
determine whether the communication unit belongs to a home network of the routing network element,
select, if the communication unit belongs to the home network of the routing network element, a first type of address information, or select, if the communication unit belongs not to the home network of the routing network element, a second type of address information, and
send the first or second type of address information to the communication unit,
wherein the communication unit is configured to
process the first or second type of address information received from the routing network element and
use the address information for setting a route for the communication unit.

4 more elements

A routing device usable in a mobile network environment and employed in a setting of a route for a communication connection of a communication unit in the mobile network environment, wherein the routing device comprises:

detecting means for detecting that a communication unit connects to the routing device;
determining means for determining whether the communication unit belongs to the home network of the routing device,
selecting means for selecting a first type of address information, when the communication unit belongs to the home network of the routing device, or for selecting a second type of address information, when the communication unit belongs not to the home network of the routing device, and
sending means for sending the first or second type of address information to the communication unit.
