Connectivity plane routing
First Claim
1. A method in a communication network, having a network control plane and a connectivity plane, of routing a connectivity plane message via the connectivity plane in a call to a mobile terminal which can be reached at a same radio access via two or more Media Gateways (MGWs) of a radio access network, the method comprising the steps of:
- routing the connectivity plane message separately from an associated network control plane message;
determining positional information, that indicates a geographical location of the mobile terminal, by a Mobile Switching Center Server (MSC Server) to which the mobile terminal is attached, and routing information, the routing information being associated with the MSC Server;
based on the positional information, selecting one of the two or more MGWs of the connectivity plane via which the connectivity plane message is to be routed to the mobile terminal; and
routing the connectivity plane message to the mobile terminal via the selected MGW of the connectivity plane.

Abstract
A method and device for routing a connectivity plane message to a mobile terminal that can be reached via two or more network nodes of a first type are described. The method includes receiving positional information indicating the geographical location of the mobile terminal, receiving routing information being associated with a network node of a second type to which the mobile terminal is attached, determining, based on the positional information, the network node of the first type via which the connectivity plane message is to be routed to the mobile terminal, and routing the connectivity plane message to the mobile terminal via the selected network node of the first type.

12. A method of controlling the routing of a connectivity plane message in a call to a mobile terminal via a connectivity plane which can be reached at a same radio access system via two or more Media Gateways (MGWs) of a radio access network and which is attached to a Mobile Switching Center Server (MSC Server), the method comprising the steps of:
-
receiving a request for routing information; generating positional information, by the MSC Server to which the mobile terminal is attached, indicating the geographical location of the mobile terminal and routing information associated with the MSC Server to which the mobile terminal is attached; transmitting a preferred routing using the positional information; and choosing one of the two or more MGWs through which the connectivity plane message is routed to the mobile terminal.

13. A network component, in a communication network comprising a network control plane and a connectivity plane, for routing a connectivity plane message via the connectivity plane in a call to a mobile terminal attached to the network component and which can be reached at a same radio access system via two or more Media Gateways (MGWs) of a radio access network, the network component comprising:
-
a first interface for receiving a request for routing information, the routing information being associated with a Mobile Switching Center Server (MSC Server) of the network control plane to which the mobile terminal is attached; a processing component for generating positional information indicating the geographical location of the mobile terminal, for routing the connectivity plane message to the mobile terminal; and
providing routing information associated with the network component; anda second interface for transmitting positional information and the routing information for a receiving network switch to select one of the two or more MGWs via which the connectivity plane message is to be routed to the mobile terminal. - View Dependent Claims (14)

15. A method, in a communication network employing a network control plane and a connectivity plane, of routing a connectivity plane message via the connectivity plane in a call to a mobile terminal that can be reached at a same radio access system via two or more MGWs of a radio access network, the connectivity plane message being routed separately from an associated network control plane message, the method comprising the steps of:
-
determining a geographic location of the mobile terminal, with respect to the two or more MGWs of the connectivity plane; receiving routing information associated with a Mobile Switching Center Server (MSCS) of the network control plane to which the mobile terminal is attached; using positional information of the mobile terminal to choose one of the MGWs of the connectivity plane via which the connectivity plane message is routed to the mobile terminal; and routing the connectivity plane message to the mobile terminal via the chosen MGW of the connectivity plane.
