摘要： The present invention describes a method for signalling to a mobility anchor point a position of a mobile node in a network using a network-based mobility management scheme for managing the mobility of the mobile node, said method comprising receiving, by a network element, from the mobile node, during or after network authentication of the mobile node, a sequence number used by a process implementing a mobile node-based mobility management scheme for managing the mobility of the mobile node, and transmitting, by the network element, to the mobility anchor point a message on a position of the mobile node in the network, wherein said message comprises the received sequence number. A common sequence number variable for BU and PBU messages is used, so that the HA is able to determine a correct transmission order of PBU/BU messages based on the sequence number in the message.

摘要： The invention relates to a method for reducing the header size of data packets by removing inner headers from the data packets, wherein at least an outer header remains for routing purposes. When removing the inner headers from a data packet, a newly configured address of the receiving and/or the transmitting entity is inserted in the remaining outer header of the data packet. Context information is provided in the receiving entities for reconstructing the removed inner headers, wherein the context information is referred to by the newly configured address that is in the source and/or destination address of the outer header. The reduced data packet is transmitted with only one header, thereby significantly reducing the size of each data packet. The original packet is completely reconstructed at the receiving entity thereby allowing to proceed with the usual processing of each data packet.

摘要： The invention relates to a method for reducing the header size of data packets exchanged between a Mobile Node (MN) and a gateway that is located between the MN and a Corresponding Node (CN). Different sort of headers are utilized between the MN and the gateway, and between the gateway and the CN. The sort of header, obtained by an optimizing procedure, allows to reduce the header size of exchanged packets on said data path section. To achieve this, a modified route optimization (RO) process is performed between the MN and the gateway, wherein the gateway acts on behalf of the CN. After completing the first RO process, the MN initiates and performs a second RO process with the gateway acting as CN. After completing both route optimization processes, data packet transmission is performed between the CN and the gateway after switching from IPsec tunnel mode to IPsec transport mode.

摘要： The invention relates to a method and mobile node capable of detecting whether or not the network to which the mobile node is attached is using a network-based mobility management function for the mobile node or not. In order to enable a mobile node to detect whether the network is using a network-based mobility function for the mobile node, upon establishment of a PDN connection or IP session, the mobile node sends a probe message to the network destined to itself and determines based on the modifications of the probe message returned to the mobile node whether the network is using a network-based mobility function for the mobile node or not.

摘要： A technology is disclosed in which, when a normal mobile node (that does not newly provide a dedicated function) is used, signaling for reconfiguring a tunnel during a mobile node movement is reduced and, furthermore, packet loss is reduced. In the technology, when an MN moves from under the control of an AR2 that is a movement origin to be under the control of an AR3 that is a movement destination, the AR3 receives an NS transmitted from the MN to the AR2. The AR3 that receives the NS destined to the AR2 transmits a “Location Update” to the AR2. The AR2 that receives the “Location Update” uses an MN management table of the relevant MN and creates “Prefix Information” and returns the “Prefix Information” to the AR3. A tunnel is established between access routers of the AR2 and AR3 through use of the “Prefix Information”, and a packet destined to the MN is transferred to the MN via the tunnel.

摘要： The invention relates to a method for informing two access gateways about each other's presence and identity, in order to establish a data path between them, thereby shortening the overall data path of data packets exchanged between two mobile nodes (MN), that are located in different networks. In particular, each access gateway is provided with the other gateway's address and additionally with the other MN's address for forwarding by the access gateway those data packets destined to the other MN to the other access gateway. A combination of Session Initiation Protocol messages (Invite and Ringing) and route optimization messages are used, so as to confer the information on the gateway's ID and MN's address to the gateways.

摘要： A method, mobile node (MN), home agent and system for handover of a MN from a first access network supporting network-based mobility to a second access network not supporting network-based mobility in a packet switched communication network including at least the MN, a mobile access gateway (MAG), a correspondent node and a home agent. The method includes performing proxy route optimization towards the correspondent node by the MAG on behalf of the MN. Handover from the first access network to the second access network is performed when the MN moves out of the first access network. A determination is made as to whether the proxy route optimization is to be maintained after the handover, and if so, information regarding the proxy route optimization is sent to the MN by the home agent.
