Abstract:
A control plane (CP) entity is to adaptively reroute user plane traffic of a mobile node (MN) with use of a segment routing (SR) for IPv6. A message indicating an attachment of the MN to the mobile network is received selecting a first user plane (UP) anchor node. A first set of home network prefixes (HNPs) are allocated to the MN. An IP traffic flow using a first HNP prefix is established between the MN and a correspondent node (CN) along a first network path—defined at least in part by the first UP anchor node and an anchor node of the CN. In response to a handover of the MN, a message indicating a subsequent attachment of the MN is received selecting a second UP anchor node. The second UP anchor node is instructed to host the first HNP prefix previously allocated by the first UP anchor node.

Claim (Index 20):
A computer program product, comprising:\n a non-transitory computer readable medium; program instructions stored on the non-transitory computer readable medium; the program instructions being executed by one or more controllers of a control plane (CP) entity for adaptively rerouting user plane traffic with use of a segment routing (SR) for IPv6 (SRv6) protocol, by:\n receiving a message indicating an attachment of a mobile node (MN) to a mobile network, wherein a first user plane (UP) anchor node and a first set of home network prefixes (HNPs) are selected for the MN, and wherein an IP traffic flow to and/or from a first HNP prefix is established between the MN and a correspondent node (CN) along a first network path defined by a first plurality of nodes, the first plurality of nodes including the first UP anchor node of the MN and an anchor node of the CP entity; \n receiving a message indicating a subsequent attachment of the MN to the mobile network in response to a handover of the MN, wherein a second UP anchor node is selected for the MN; and \n after receiving the message indicating the subsequent attachment of the MN to the mobile network:\n provisioning the second UP anchor node with one or more rules, for instructing the second UP anchor node to host the first set of HNP prefixes previously allocated to the MN; and \n provisioning at least one of the first UP anchor node, the second UP anchor node, and the anchor node of the CN with one or more rules to perform SRv6 routing of IP traffic flow to and/or from the first HNP prefix along a second network path defined by a second plurality of nodes, for optimizing the IP traffic flow.
