摘要： A mobile communication network includes a plurality of access nodes that can serve different roles in support of a communication session with a mobile station. An access node can serve as a connecting node that receives access requests the mobile station, as an anchor node to anchor a radio packet connection with a core network for the communication session; or as a primary node to store session information for the communication session. When the communication session is established, the anchor node for the communication session may select another access node to serve as the primary node. Session information can be stored at both the anchor node and primary node so that data can be delivered to the mobile station if either one of the anchor node and primary node are available.

摘要： A mobile communication network comprises a plurality of access nodes, wherein each access node allocates mobile station identifiers to mobile stations from an assigned group of mobile station identifiers. The mobile station identifiers in each group have a common property that identifies the corresponding access node. The mobile station identifier may be used, for example, to locate session information for a mobile station when a mobile station moves between access nodes.

摘要： In a mobile communication network comprising a plurality of access nodes, session information for a communication session is stored in one access node and may be requested by a peer access node. A requesting access node determines the location of session information based on the mobile station identifier associated with the communication session. If the session information is transferred to the requesting node, the requesting node may allocate a new mobile station identifier to the mobile station for the communication session.

摘要： A cell switching method reduces the time to setup a connection between a target access node and a packet data serving node when a mobile station switches between a source access node and the target access node. A source access node receives sector selection from a mobile station indicating that the mobile station is about to switch to a target access node. The source access node sends a signaling message to a packet data serving node responsive to receipt of said sector selection indication that identifies the target access node selected by the mobile station. The packet data serving node can then begin bi-casting packet data for the mobile station to both the source access node and the target access node for a predetermined period of time, after which the packet data serving node stops sending packet data to the source access node.

摘要： An access node anchoring a connection to, e.g., a PDSN in a core network establishes a session with a mobile station and assigns the mobile station an identifier such as a UATI. The anchor node sends the UATI to the PDSN, such as in a GRE key where the data link is a GRE tunnel. If the anchor node fails and data addressed to the mobile station comes to the PDSN, it may initiate a page for the mobile using the UATI. The anchor node may additionally send the PDSN the session seed and optionally the mobile station's network location. A registration zone may be defined to include access nodes within a predetermined distance of the anchor node, and the mobile station forced to re-register when moving outside of the registration zone. In this case, the PDSN may initiate a page for the mobile station only within the registration zone.

摘要： A method and apparatus for transferring session information from a source access node to a target access node reduces the delay in the delivery of packets for delay intolerant applications such as voice over IP. A protocol data table is stored in the target access node. The source access node sends the target access node a session configuration token that can be used to lookup session information in the protocol data table.

摘要： A carpet and floor vacuum device with an improved suction head is provided comprising a curved, fluorinated molding mounted on a vacuum cleaner head. The suction head is designed to move along the surface of the carpet, rather than penetrating into the carpet itself. The polymer molding defines a plurality of inlet perforations laterally-spaced along the curved surface, and the perforations are connected to an air-fed manifold. Following application of cleaning fluid to the carpet or floor, air is fed from the manifold into the carpet or onto the floor. Material including Ingested air, debris and spent liquid, are then removed from the carpet or from the floor and then returned to the perforations from the manifold. This material is then removed to a conventional vacuum collector, thereby drying out the carpet or floor. Use of a curved, fluorinated surface provides a smooth movement along the carpet surface without severely abrading the carpet fibers. When used either on a carpet or floor surface, an air buffer is formed between the suction head, thereby assisting in movement of the vacuuming device. In addition, use of a curved fluorinated surface further reduces abrasion.
摘要翻译：提供具有改进的吸头的地毯和地板真空装置，其包括安装在真空吸尘器头上的弯曲的氟化模制件。吸头被设计成沿着地毯的表面移动，而不是穿入地毯本身。聚合物模制件限定沿着弯曲表面横向间隔开的多个入口穿孔，并且穿孔连接到供气歧管。在将清洁流体施加到地毯或地板之后，空气从歧管进入地毯或地板上。然后从地毯或地板中取出包括食入的空气，碎屑和废液的材料，然后从歧管返回穿孔。然后将该材料除去到常规的真空收集器，从而干燥地毯或地板。弯曲的氟化表面的使用提供沿着地毯表面的平滑运动，而不会严重磨损地毯纤维。当在地毯或地板表面上使用时，在吸头之间形成空气缓冲器，从而有助于抽真空装置的移动。此外，使用弯曲的氟化表面进一步减少磨损。
