Abstract

Disclosed is a solution for controlling a routing of data traffic of a roaming ter-minal device with data network, the method includes: detecting if the terminal device is served by a private network, and in accordance with a detection re-sult performing one of: selecting a network node of the private network for managing the routing if the roaming terminal device is served by the private network; or selecting a network node of a mobile communication network for managing the routing if the terminal device is not served by the private net-work, the method further including: generating a control signal to a respective network the selected network node resides for assigning a responsibility for managing the routing.

First claim

What is claimed is:

1 . A method for controlling a routing of data traffic of a roaming terminal device with data network, the method, performed by a control system, comprising:
detecting whether or not the roaming terminal device is served by a private network to obtain a detection result; in accordance with the detection result, one of:
selecting a network node of the private network configured to manage the routing of the data traffic of the roaming terminal device in response to the detection result indicating that the roaming terminal device is served by the private network, and
selecting a network node of a mobile communication network configured to manage the routing of the data traffic of the roaming terminal device in response to the detection result indicating that the roaming terminal device is not served by the private network; and
generating a control signal to a respective network the selected network node resides to assign a responsibility for managing the routing of the data traffic of the roaming terminal device.

2 . The method of claim 1 , wherein the detection that the roaming terminal device is served by the private network is performed based on at least one of the following: an identifier of a serving network received in a communication from the terminal device, and a location of the terminal device.

3 . The method of claim 1 , wherein the selection of the network node of the mobile communication network is performed based on a technical parameter indicative of a communication of the terminal device in the mobile communication network serving the roaming terminal device.

4 . The method of claim 3 , wherein the technical parameter is indicative of a radio technology applied to the communication of the terminal device in the mobile communication network serving the roaming terminal device.

5 . The method of claim 3 , wherein the selection of the network node is performed by selecting the network node of a home communication network in response to a detection that a data rate of the data traffic is below the predefined limit.

6 . The method of claim 1 , wherein the selection of the network node is performed by selecting the network node configured to manage a regional data traffic in response to a detection that both the roaming terminal device and another communicating party reside in a same regional area.

7 . A control system for controlling a routing of data traffic of a roaming terminal device with data network, the control system comprising:
one or more processors configured to:
detect whether or not the roaming terminal device is served by a private network to obtain a detection result,
in accordance with the detection result, one of:
select a network node of the private network configured to manage the routing of the data traffic of the roaming terminal device in response to the detection result indicating that the roaming terminal device is served by the private network, and
select a network node of a mobile communication network configured to manage the routing of the data traffic of the roaming terminal device in response to the detection result indicating that the roaming terminal device is not served by the private network, and

generate a control signal to a respective network the selected network node resides to assign a responsibility for managing the routing of the data traffic of the roaming terminal device.

8 . The control system of claim 7 , wherein the one or more processors is configured to perform the detection that the roaming terminal device is served by the private network based on at least one of the following: an identifier of a serving network received in a communication from the terminal device, and a location of the terminal device.

9 . The control system of claim 7 , wherein the one or more processors is configured to perform the selection of the network node of the mobile communication network based on a technical parameter indicative of a communication of the terminal device in the mobile communication network serving the roaming terminal device.

10 . The control system of claim 9 , wherein the one or more processors is configured to interpret the technical parameter as an indication of a radio technology applied to the communication of the terminal device in the mobile communication network serving the roaming terminal device.

11 . The control system of claim 9 , wherein the one or more processors is configured to perform the selection of the network node by selecting the network node of a home communication network in response to a detection that a data rate of the data traffic is below the predefined limit.

12 . The control system of claim 7 , wherein the one or more processors is configured to perform the selection of the network node by selecting the network node configured to manage a regional data traffic in response to a detection that both the roaming terminal device and another communicating party reside in a same regional area.

13 . The control system of claim 7 , wherein the control system is at least one apparatus arranged in an IP exchange network (IPX).

14 . A communication system comprising:
a plurality of mobile communication networks, a terminal device serving as a roaming terminal device in at least one of the plurality of mobile communication networks; and a control system configured to:
detect whether or not the roaming terminal device is served by a private network to obtain a detection result, and
in accordance with the detection result, one of:
select a network node of the private network configured to manage the routing of the data traffic of the roaming terminal device in response to the detection result indicating that the roaming terminal device is served by the private network, and
select a network node of a mobile communication network configured to manage the routing of the data traffic of the roaming terminal device in response to the detection result indicating that the roaming terminal device is not served by the private network, and

generate a control signal to a respective network the selected network node resides to assign a responsibility for managing the routing of the data traffic of the roaming terminal device.

15 . A non-transitory computer-readable medium on which is stored a computer program comprising instructions which, when the computer program is executed by a computer, cause the computer to perform a method comprising:
detecting whether or not a roaming terminal device is served by a private network to obtain a detection result; in accordance with the detection result, one of:
selecting a network node of the private network configured to manage the routing of the data traffic of the roaming terminal device in response to the detection result indicating that the roaming terminal device is served by the private network, and
selecting a network node of a mobile communication network configured to manage the routing of the data traffic of the roaming terminal device in response to that the detection result indicating that the roaming terminal device is not served by the private network; and
generating a control signal to a respective network the selected network node resides to assign a responsibility for managing the routing of the data traffic of the roaming terminal device.
