  • Patent number: 8144650
    Abstract: A method of services request in a packet switched telecommunications network comprising a Gateway GPRS Support Node (GGSN) arranged for communication with a Serving GPRS Support Node (SGSN). During activation of a subscriber session, receiving by the GGSN, from the SGSN in an Update PDP Context Request message, data comprising both 1) an Internet Protocol (IP) address and user plane tunnelling endpoint identifier (TEID) for a Radio Network Controller (RNC) and 2) an IP address and user plane TEID of the SGSN; the GGSN nominally utilizes the IP address and TEID of the RNC for the subscriber session. If an error indication is received by the GGSN indicating that the RNC has restarted, it discards the IP address and TEID corresponding to the RNC and utilizes the IP address and TEID corresponding to the SGSN, whereby the GGSN and SGSN can maintain the subscriber session in the event of an RNC restart.

  • Patent number: 8144661
    Abstract: The present invention relates to a packet data support node (10A) in a core network and connectable to at least one radio access network over a radio network control node. The packet data support node (10A) comprises duplicating means (12A) for duplicating original downlink data packets intended for a mobile station for which a hand-over is performed from the packet data support node acting as source node to a packet data support node acting as target node, control means (HA) for activating sending of the duplicated data packets to the packet data support node acting as a target node for forwarding to the mobile station such that the original downlink data packets are sent to the mobile station over a source radio access node from the source packet data node (10A). The duplicated data packets are sent to the mobile station over a target radio access node from the packet data source node acting as target node.

  • Patent number: 8144573
    Abstract: A method and apparatus that utilizes the synchronization channel (SCH) by the user equipment (UE) to obtain time synchronization information and to perform cell search. In order to perform the SCH detection, only a correlation between the known SCH signal and the received sequence is needed, hence the FFT is not involved in the synchronization step. Typically the SCH and pilot symbols are transmitted with a constant power which is the same for all base stations. Hence, based on the serving cell (SC) SCH and pilot symbols, the power relation between these signals is estimated and the ratio applied when performing time synchronization to other cells (i.e. correlation the received sequence with the SCH from that particular NC) to estimate the pilot signal strength for the NB cell.

  • Patent number: 8142951
    Abstract: The invention concerns a monopolar fuel cell endplate (4) of the type with proton exchanging membrane consisting of a cathode or anode monopolar half-plate (41) attached to a closure plate (42).

  • Publication number: 20120067211
    Abstract: A dense hydrogen-permeable layer, such as palladium or palladium alloy, is deposited on a porous hollow fiber. A porous hollow fiber is defined as having an inner diameter of approximately 30 microns to approximately 1500 microns and an outer diameter of approximately 100 microns to approximately 2000 microns. This allows an order-of-magnitude increase in the surface per volume ratio in a hydrogen separation or purification module, or a membrane reformer or reactor.

  • Publication number: 20120069888
    Abstract: An objective quality assessment method for obtaining an improved estimate of a perceptual quality degradation of a processed signal, and an arrangement for executing such a method, is provided, which is executed on a processed signal and an associate reference signal. Both signals are split up into associated frame-pairs after into frames which either all or selected frame-pairs are processed further, by creating a reference residual signal and a processed residual signal for each frame-pair, calculating separate ratios of p-norms on both residual signals, and by calculating and storing a per-frame frame-pair quality estimate on the basis of the ratios of p-norms for each selected frame-pair. An objective per-signal quality estimate that is proportional to the perceptual quality Create degradation is then provided by aggregating the calculated per-frame-pair quality estimates.
