Mobile Node Mapping Information Update Triggering Method, MS and MN
First Claim
1. A mobile node (MN) mapping information update triggering method, applied to a locator/identifier separation protocol (LISP) network, wherein, said method comprising:
- a mapping server (MS) receiving a mapping registration message sent by a MN attached to said MS for updating mapping information;
said MS acquiring information of a communication peer, and according to the information of said communication peer, sending a mapping update message to a peer mapping cache device corresponding to said MN'"'"'s communication peer node to trigger said peer mapping cache device to update cached mapping information.

Abstract
A mobile node mapping information update triggering method, information reporting method, mapping server and mobile node, applied to a Locator/Identifier Separation Protocol (LISP) network, wherein the mobile node mapping information update triggering method comprises: a mapping server (MS) receiving a mapping registration message for updating mapping information transmitted by a MN attached to the MS; the MS acquiring the information of a communication peer, and according to the information of the communication peer, transmitting a mapping update message to a peer mapping cache device corresponding to the communication peer of the MN, thus triggering the peer mapping cache device to update the cached mapping information. In the abovementioned solution, it overcomes the problem that the mobile node has to bear a large amount of signaling overheads in order to update the peer cache.
