  • Publication number: 20110176505
    Abstract: A method, a system, and a Network Element (NE) for access control are disclosed. The access control method includes: receiving an access request sent by a User Equipment (UE), wherein the access request carries a temporary identifier allocated by a network node to the UE, and the temporary identifier comprises a user's service policy information; and performing access control over the UE according to the service policy information in the temporary identifier. The temporary identifier allocated by the network node to the UE carries the user's service policy information. Therefore, when the UE sends an access request, the UE lets the access request carry the user's service policy information, the access control NE can exercise access control over the UE according to the service policy information, and the access control is exercised over the user when the user sends the access request.

  • Publication number: 20100234019
    Abstract: A mobility management entity (MME) information deleting method includes: receiving a message sent by a first MME; and if needed, determining whether it is necessary to delete information about the first MME according to version information about the first MME. The method further includes: receiving a message sent by a target MME, in which the message carries version information about a source MME acquired by the target MME or an indication of deleting information about the source MME added by the target MME; and deleting the information about the source MME according to the message. A network device for deleting MME information is also provided. According to the present invention, a network device, such as a home subscriber server (HSS), is capable of acquiring version information about a source MME or receiving an indication of deleting information about the source MME, so as to determine whether it is necessary to delete the information about the MME.

  • Publication number: 20100220689
    Abstract: A resource release control method, a communication system, and a device are configured to delete a bearer context on an original-side heterogeneous-system management network element (NE) even if a target-side management NE does not support interaction with a serving gateway (S-GW) and does not support an idle mode signaling reduction (ISR) mechanism. The resource release control method includes: acquiring version information of a target-side management NE, when a user equipment (UE) activating an ISR mechanism is handed over from an original-side network to a target-side network; and deleting a bearer of an original-side heterogeneous-system management NE, if the version information indicates that the target-side management NE does not interact with an S-GW and does not support the ISR mechanism. Meanwhile, a communication system and a relevant device are also provided.

  • Publication number: 20100056147
    Abstract: A bearer suspension method, a bearer resumption method, and a gateway agent are provided. The bearer suspension method includes the following steps. A gateway agent receives a Bearer Suspend Request sent by a mobility management entity (MME) when a user equipment (UE) is handed over from an evolved universal mobile telecommunications system (UMTS) terrestrial radio access network (EUTRAN) to a global system for mobile communications (GSM)/enhanced data rates for GSM evolution (EDGE) radio access network (GERAN). A bearer that needs to be suspended is suspended according to the request. The bearer resumption method includes the following steps. In a process of handover of a UE from a GERAN to an EUTRAN or tracking area update (TAU) or Service Request, the gateway agent receives a Bearer Resume Request sent by an MME. A bearer that needs to be resumed is resumed according to the request.

  • Patent number: 6454987
    Abstract: A laminated substrate is prepared, the laminated substrate having two layers including a first film and a second film in tight contact with the first film, the second film being made of a material capable of being etched with synchrotron radiation light. A mask member with a pattern is disposed in tight contact with the surface of the second film of the laminated structure or at a distance from the surface of the second film, the pattern of the mask member being made of a material not transmitting the synchrotron radiation light. The synchrotron radiation light is applied on a partial surface area of the second film via the mask member to etch the second film where the synchrotron radiation light is applied and to expose a partial surface area of the first film on the bottom of an etched area.

  • Patent number: 5966967
    Abstract: The present invention relates to a process for the cryogenic distillation of air in a distillation column system that contains at least one distillation column wherein the boil-up at the bottom of the distillation column producing the oxygen product is provided by condensing a stream whose nitrogen concentration is equal to or greater than that in the feed air stream. The process of the present invention comprises the steps of: (a) generating work energy which is at least ten percent (10%) of the overall refrigeration demand of the distillation column system; (b) work expanding a process stream to produce additional work energy such that the total work generated along with step (a) exceeds the total refrigeration demand of the cryogenic plant; and (c) using the work which is generated in excess of the refrigeration need of the distillation column system to cold compress a process stream at a temperature lower than the ambient temperature.
