A method for propagating a movement event message of a network entity, including: step 1) a network device maintaining a historical forwarded information list, wherein a network device capable of receiving a movement event message from an external system or device maintains an uplink port information table; step 2) after receiving the message, the network device performs matching using the table to obtain a forwarding port and forwarding information of the message, and constructs a movement event forwarding message using the information and forwards through the forwarding port; and step 3) after a device receives the message, searching for a matching forwarding port and forwarding information of the message in the information list, modifying the message using the forwarding information, and forwarding the modified message through the forwarding port. The method is able to propagate a movement event message to a network device responsible for related data transmission and forwarding.

Method for propagating movement event message of network entity

A ICN packet forwarding method, including: step 1) maintaining, by a network forwarding device, a network entity ID association state table, which is used for recording a state of the binding relationship between a network entity ID and a network address to which the network entity is associatively bound; after a network address binding relationship of the network entity changes due to location movement thereof, adding or updating, by the network forwarding device, a record of the network entity in the network entity ID association state table according to notification information of the network entity; and step 2) upon receipt of an ICN packet, by the network forwarding device, determining whether the ICN packet needs to be processed, according to information of the current network entity ID association state table; if yes, forwarding after processing the ICN packet; otherwise, directly forwarding the packet.

ICN packet forwarding method

A fast query method for a mobile network entity dynamic location information, using a distributed container hierarchical nested structure to process registration and queries for location information, includes: after a network entity connects to a network attachment point after moving and obtains a new network address assignment, determining a series of a registered container, and then registering new location information corresponding to where the network entity is currently located, the location information containing at least current network address information; when a network forwarding device learns that the network entity is currently un-reachable, querying the new location information of the network entity from the container where the network entity was located before moving; and the container where the network entity was located before moving, after receiving the query request, obtains the new location information of the network entity by searching in the container and in a peer neighboring container set.

Fast query method for dynamic location information of mobile network entity

A mobile signaling management method uses a distributed container with a hierarchical nested structure to process the registration and query of location information of user equipment, including: first user equipment connected to a first network device, to obtain a first network address allocated by the first network device; the first user equipment registering to a first mobility management node binding information between the name of the first user equipment and the first network address, the first mobility management node being a node where the first user equipment is located after movement; the first user equipment updating to a second network device the binding information between the name of the first user equipment and the first network address; and the first user equipment updating to second user equipment at the communication peer end the binding information between the name of the first user equipment and the first network address.
