Abstract: Method for managing mobility of a mobile device (MS) within a network using a proxy MIPv6 protocol comprising MAG and LMA logical functions, wherein MAG issues a PBU to bind the mobile device (MS) with the LMA, a LMA-time being initialized and maintained within the LMA and the method comprising a relative time synchronization procedure between LMA and all of the MAG connected to it, said procedure providing that each MAG sends a PBU with specific semantics to request the LMA-time, the PBU acknowledgement (PBU-Ack) sent by the LMA including such LMA-time, said LMA-time being further maintained within each MAG, the method further comprising a binding procedure in which all of the MAG insert in each PBU sent a timestamp including the current maintained LMA-time.

Abstract: A call handover method for an Internet Protocol communication network using hierarchical mobility management comprising a mobility anchor point connected to first and second access routers and to a home agent of a mobile node having first local and regional care-of addresses and communicating with another node consists in, if the mobile node detects the second access router: i) communicating the address prefix of the second access router to the mobile node in order for it to construct a second local care-of address, ii) communicating the second local care-of address, the first regional care-of address and an information bit having a value indicating double temporary addressing to the anchor point in order for it to store the second local care-of address in corresponding relationship to the first regional care-of address and then forward packets addressed to the mobile node to the first and second access routers, and iii) disconnecting the mobile node from the first access node and then deleting the first loca

Abstract: One object of the present invention is an architecture for interworking between WiMAX and 3GPP networks, said architecture comprising: an interworking node IWK which connects with the 3GPP Packet Core Network using 3GPP Gi interface, face, and with the WiMAX Connectivity Service Network CSN using WiMAX R3 interface.

Abstract: A method is dedicated to managing interworking between a WLAN network and a mobile network both connected to a core network comprising at least two GGSN nodes (G1, G2) connected to respective service networks, an SGSN node (NS) connected to the mobile network and to the GGSN nodes, and at least two tunnel termination gateways (T1, T2) connected to the WLAN network and to the GGSN nodes.

Abstract: A method, dedicated to the management of the interworking between a wireless local area network and a mobile network, consists, in case of reception by an SGSN node (S1) of the mobile network of a routing area updating report sent by a mobile station (MS) during a transfer from the wireless local area network to the mobile network of a service session involving that mobile station (MS) and a tunnel termination gateway (TTG) and a GGSN node (NG) of the mobile network, via tunnels, i) to determine the address of a proxy SGSN node (S2) of the mobile network from the routing area identifier contained in the request in order to send that node (S2) a message requesting the transfer SGSN context of the mobile station (MS), ii) to recover from a home location register (HLR) of the mobile network, by means of the proxy SGSN node (S2), the address of the gateway (TTG) to send it a message requesting the transfer SGSN context of the mobile station, and iii) on receipt of the transfer SGSN context by the proxy SGSN node

Abstract: The invention concerns a method of management of interworking between at least one wireless local area network and one mobile network comprising the following steps: in the case of a first handover, from the wireless local area network to the mobile network, of a communication session involving a mobile station, the communication session using, before the first handover, on the one hand an end-to-end tunnel between the mobile station and a TTG gateway and on the other hand a GTP tunnel between the TTG gateway and a GGSN node: replacement of the GTP tunnel between the TTG gateway and the GGSN node by a GTP tunnel between an SGSN node and the GGSN node; clearing down of the end-to-end tunnel between the mobile station and the TTG gateway; in the case of a second handover, from the mobile network to the wireless local area network, of a communication session involving a mobile station, the communication session using, before the second handover, a GTP tunnel between an SGSN node and a GGSN node, the method compr

Abstract: A call handover method for an Internet Protocol (IP) communication network using hierarchical routing comprising first and second mobility anchor points (P1, P2) connected to respective first and second access routers (R1, R2) and a home agent (EA) of a mobile first node (T1) communicating with a second node (T2) consists in, when the mobile first node (T1) detects the second access router (R2): i) determining the address prefix of the second access router (R2) in order to communicate it to the mobile first node (T1) in order for the latter to construct additional local and regional care-of addresses, ii) communicating the additional local care-of address to the first anchor point (P1) in order for it to set up a temporary tunnel (TU) to the second access router (R2) in order to forward packets addressed to the mobile first node (T1) to the second access router (R2), iii) connecting the mobile first node (T1) to the second access router (R2) in order to forward to it the packets received via the temporary tun
