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.

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. During a communication session, a connecting node receiving a connection request from a dormant mobile station may request session information from the primary node. The radio packet connection may also be moved to the connecting node.

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.

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.

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.

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.

Methods, systems, and devices are described for establishing a wireless communications link at an aircraft terminal (AT). An AT may determine a timing offset based on the propagation delay between the AT and a ground station, which in some cases may be more than 100 kilometers away. The AT may then transmit an initial access message to the ground station based on the determined timing offset. In some embodiments, the AT may receive an access response message from the ground station that includes a timing alignment value and adjust the timing offset based on this value. The AT may transmit a connection message to the ground station that includes AT location information. This information may be used by the ground station to facilitate beamforming.
