Patent Images
1. A method comprising:
- receiving, at a mobility support function (MSF) logic-enabled first edge router in a network including a plurality of label switch (LS) routers, a discovery signal from a first mobile node;
registering the first mobile node in response to receiving registration information related to the discovery signal, from the first mobile node, wherein the registration information includes first data including at least one networking parameter for the first mobile node;
assigning a mobility label to the first mobile node, including associating the first data with the mobility label;
distributing, in accordance with a multi-protocol border gateway protocol, messages describing the mobility label and the first data to a plurality of edge routers including an MSF logic-enabled second edge router, in the network to create a label switched path; and
routing communication messages to be exchanged between the first mobile node and a second mobile node, along the label switched path in the network.

Abstract
A device may receive a discovery signal from a mobile node, register the mobile node in response to receiving the discovery signal from the mobile node, assign a mobility label to the mobile node after the registration, distribute messages describing the mobility label and the mobile node to edge routers in the network to create a label switched path, and route communication messages from a remote node to the mobile node along the label switched path in the network.

10. A device comprising:
-
a mobility support function (MSF) module to; exchange a plurality of messages with a first mobile node responsive to receiving a discovery signal from the first mobile node, register the first mobile node in response to receiving registration information included in at least one message of the plurality of messages, wherein the registration information includes first data related to at least one networking parameter for the first mobile node, and link the first mobile node to the device via a communication path; and a routing module to; propagate a mobility label, associated with the first data, from the device to a plurality of edge routers including an MSF logic-enabled edge router, in a network, in accordance with an inter-domain signaling protocol that includes a multi-protocol border gateway protocol, and distribute the mobility label to routers that are within a multi-protocol label switching (MPLS) network portion of the network, in accordance with a distribution protocol. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method comprising:
-
receiving, at a mobility support function (MSF) logic-enabled first edge router in a network including a plurality of label switch (LS) routers, a discovery signal from a first mobile node; registering, at the first edge router, the first mobile node, including storing first data identifying the first mobile node; assigning, by the first edge router, a first mobility label to the first mobile node after the registration, wherein the first mobility label identifies the first mobile node; distributing, in a multi-protocol label switching (MPLS) network portion within the network and in accordance with a multi-protocol border gateway protocol, messages describing the first mobility label and the first data, to a plurality of edge routers including an MSF logic-enabled second edge router, in the network, to create a first label switched path (LSP); and routing communication messages from a remote to be exchanged between the first mobile node and a second mobile node attached to the second edge router, along the first LSP in the MPLS network.
