  • Patent number: 8411650
    Abstract: A method for providing a virtual private network by home agent in a mobile IP environment includes providing a home agent operable to receive a registration request from a foreign agent and negotiate conditions of attachment of a mobile node to the foreign agent and further operable to store an IP address of the foreign agent in response to the negotiated conditions. The method also includes receiving, at the home agent, from the foreign agent, a registration request for the mobile node. The method also includes determining, by the home agent, a virtual private network membership of the mobile node based on a characteristic associated with the mobile node. The method further includes mapping the mobile node to an identifier associated with the home agent and transmitting the mapping to the foreign agent. The identifier is indicative of the virtual private network membership of the mobile subscriber.

  • Patent number: 8041819
    Abstract: A method for providing network services includes receiving a mobile station identifier (MSID) from a mobile node at a packet data serving node. The packet data serving node is operable to communicate with the mobile node. The method includes receiving a registration request (RRQ) from the mobile node and appending the MSID to the RRQ. The method includes forwarding the RRQ to a home agent. The home agent is operable to communicate with the packet data serving node. The method also includes receiving an Internet Protocol (IP) address from the home agent. The IP address corresponds to the MSID. The MSID may be included in a normal vendor specific extension (NVSE) constructed by the packet data serving node. Appending the MSID to the RRQ may comprise appending the NVSE to the RRQ.

  • Publication number: 20110138687
    Abstract: An improved beneficiation process to produce low ash clean coal from high ash coals, comprising: preparing a coal slurry from fine coal and water and discharging it to a first reactor; preparing an alkali solution of NaOH and water and discharging it to a first reactor; carrying-out a leaching reaction between the coal and the alkali solution inside the first reactor; transferring the reaction mixture to a second reactor for filtration and washing to produce a filter cake; preparing a diluted acid solution in a second tank and delivering it to a second reactor; preparing a diluted alkali solution in a third tank and delivering it to a second reactor; feeding a coal slurry prepared from the filter cake into the second reactor for washing and transferring to a second filtration unit; transferring the product after filtration to a third reactor; carrying-out different leaching reaction sequences in the first, second, and third reactors; and transferring to a fifth tank the treated coal filter cake for drying.

  • Patent number: 7411927
    Abstract: According to one embodiment of the present invention, a method of optimizing point-to-point sessions is disclosed. A registration request is received from a mobile node. The mobile node communicates with a current packet controller function serviced by a packet data serving node. Whether the registration request comprises a previous access network identifier is determined. The previous access network identifier identifies a previous packet controller function. Whether the mobile node is serviced by a mobile Internet Protocol is determined. Next, whether the mobile node communicated with a previous packet controller function serviced by the packet data serving node is determined. The method concludes by deciding whether to negotiate a point-to-point session for the mobile node in response to on the determinations.

  • Patent number: 7269727
    Abstract: A method for executing authentication in a network environment is provided that includes retrieving a group profile from an authentication, authorization, and accounting (AAA) server in response to receiving a request from a first end user and locally caching the group profile. A service may be provided to the first end user based on information included within the group profile and associated with the first end user. A request may be received from a second end user. It is then determined if the second end user is included within the group profile such that in cases where the second end user is included in the group profile the group profile can be locally cached in order to provide a service to the second end user without having to communicate with the AAA server.
