  • Patent number: 10154527
    Abstract: A method includes, at a user equipment, combining a message requesting the radio resource connection and a message requesting at least one service into a single message. The single message is transmitted from the user equipment to a network element in a wireless network. Another method includes receiving, from a user equipment, a single message including both a message requesting a radio resource connection and a message requesting at least one service. In response to the message requesting radio resource connection, performing radio resource control connection establishment for the user equipment in order to establish the radio resource control connection between the user equipment and at least one of a plurality of network elements of a wireless network.

  • Patent number: 9007982
    Abstract: A method to control cell selection and/or re-selection in a communication system comprising a plurality of cells with which terminal devices may communicate, the method including the steps of: determining that a terminal device is to start a session for a certain service, the service using a reception frequency; based on that determination, changing at least one cell selection and/or re-selection parameter in respect of the terminal device with the effect that a subsequent cell selection and/or re-selection performed by the device would favor cells that use the reception frequency used in the service session over other cells.

  • Patent number: 8442000
    Abstract: A new protocol data unit is used in communications in a radio access network. When a user equipment requests a radio resource controller connection, the UE includes its identity in the request message. In establishing the connection to UE, a serving radio network controller allocates a logical channel to the UE for communications and identifies the logical channel in the header of the protocol data unit so as to allow a receiver of the PDU to know the UE identity in an out-of-band signaling fashion, depending upon a state of the transmitter of the PDU. When the transmitter changes its state, the receiver can change state accordingly. The new PDU structure allows continuous reception of the HS-DSCH downlink channel during state transition form CELL_FACH or CELL_PCH or URA_PCH to CELL_DCH and vice versa. This new PDU structure also allows continuous HS_DSCH retransmissions.

  • Patent number: 6696065
    Abstract: A multi-component vaccine composition is described comprising acellular pertussis vaccine components, diphtheria toxoid, tetanus toxoid and inactivated poliovirus. The composition also may contain a conjugate of a capsular polysaccharide on Haemophilus influenzae type b and tetanus toxoid or diphtheria toxoid, which may be reconstituted from a lyophilized state by the other component. The administration of the multiple component vaccine resulted in no diminution of the immunogenicity of any component as a result of interference by other components of the vaccine.

  • Patent number: 6399076
    Abstract: Acellular pertussis vaccines comprise purified toxin or toxoid thereof, filamentous haemagglutinin, pertactin and fimbrial agglutinogens formulated to confer protection to at least 70% of members of an at-risk population. The fimbrial agglutinogens may be prepared from a Bordetella strain, particularly a B. pertussis strain, by a multiple step procedure involving extraction of the fimbrial agglutinogens from cell paste and concentrating and purifying the extracted material.

  • Patent number: 3935244
    Abstract: A deactivated hydrocarbon conversion catalyst, which is a combination of a platinum group component, a rhenium component, a halogen component, and a sulfur component with a porous carrier material and which has been deactivated by deposition of carbonaceous material thereon during a previous contacting with a hydrocarbon charge stock at hydrocarbon conversion conditions, is regenerated by the sequential steps of: (1) stripping the sulfur therefrom by contacting with a first gaseous mixture comprising hydrogen, H.sub.2 O, and HCl; (2) purging hydrogen from contact with the catalyst with an inert gas stream; (3) burning carbon from the resulting catalyst at a relatively low temperature and a relatively high pressure with a substantially sulfur-free second gaseous mixture containing relatively small amounts of oxygen, H.sub.
