摘要:
In a system (100) that includes at least one mobility server (40, 50), at least one edge mobility agent (60) and a plurality of mobile nodes (20, 30), a method for local routing between two mobile nodes that includes the steps of: receiving a first care-of address for a first mobile node; detecting an edge mobility agent having knowledge of the first care-of address; determining, based upon at least one condition, that the edge mobility agent can perform local routing of at least one datagram for the first mobile node; and instructing the edge mobility agent to perform local routing of at least one datagram between the first mobile node and a second mobile node that has a second care-of address that is known to the edge mobility agent.

A first device (104) receives a first message from a second device (100). Upon receipt of the first message, the first device transmits a registration request to the second device for pre-registration with a third device (102). If the second device does not receive the registration request from the first device within a predetermined time period, the second device re-transmits the first message to the first device if a communication link with the first device is still operational. If the first device receives the first message again from the second device prior to attaching to the third device, the first device re-transmits the registration request to the second device. If registration with the third device is not pending when the first device attaches to the third device, the third device transmits a second message to the first device to solicit a registration request from the first device.
摘要:
A method and apparatus for multicast communication, wherein the apparatus is configured for performing the method that includes the steps of: communicating (210) a request to a server to join a first multicast group, the first multicast group associated with a first multicast address; determining (220) a second multicast group corresponding to the first multicast group, the second multicast group having a second multicast address; joining (230) the second multicast group to create a corresponding multicast tunnel; receiving (240) a first multicast packet from the server using the multicast tunnel, the first multicast packet comprising the first and second multicast addresses; removing (250) the second multicast address from the first multicast packet; and forwarding (260) the first multicast packet comprising the first multicast address to an entity.
摘要:
A method for is disclosed in which a first message is received from a first device. Upon receipt of the first message, a registration request is transmitted via the first device to a home agent for pre-registration of a co-located care-of address associated with a second device. The registration request includes the co-located care-of address associated with the second device. If the first message is received again from the first device prior to attaching to the second device, the registration request is re-transmitted via the first device.
摘要:
A method for improving the reliability of a low latency handoff is disclosed. The method comprises receiving a first message from a first device. Upon receipt of the first message, transmitting a registration request via the first device to a home agent for pre-registration of a co-located care-of address associated with a second device, wherein the registration request comprises the co-located care-of address associated with the second device. If the first message is received again from the first device prior to attaching to the second device, re-transmitting the registration request via the first device.
摘要:
A registration method in a system having a hierarchical structure (100) that includes a mobile node (20), at least one FA (42), at least one GFA (40) and an HA (30). The method includes the steps of: intercepting (210) a registration request (300) from a mobile node to its HA, the registration request including a first care of address (360) for the mobile node; determining (220) whether there is an existing entry in a visitor list for the mobile node; if the entry exists, updating (230) the entry; if no entry exists, creating an entry (250) in the list for the mobile node, adding (260) a second care of address as an extension to the registration request, and sending (270) the registration request with the address extension to the HA; and sending (240) a registration reply to the mobile node.
摘要:
The present invention relates to methods of authenticating an electronic device in a mobile network. A method of authenticating an electronic device comprises a first mobile network controller receiving an authentication request from the electronic device in a mobile network 105; searching for an authentication credential 110 at a first mobile network controller by searching in a local database of the first mobile network controller; and, searching for an alternate authentication server to fulfill the authentication request 115, if the authentication credential is not found in the local database of the first mobile network controller.
摘要:
A method for use by middleware in a communication system (100) that includes the steps of: enabling a group of behavior sets (220) for use by the middleware; operating (330) in accordance with a first behavior set from the group (220); receiving at least one trigger (342, 346); selecting (350) a second behavior set from the group (220) based upon the at least one trigger (342, 346); and operating in accordance with the second behavior set (330).
摘要:
System and method are provided for establishing internet protocol (IP) communication between a mobile node (MN) and one or more mobile networks. The method includes receiving (100) a request from a MN when the MN joins a first mobile network, creating (105) routing information indicating a home address of the MN, and announcing (110) the home address to the nodes of the mobile network(s). The request indicates the home address of the MN.
