  • Publication number: 20100062485
    Abstract: The present invention relates to a process for producing a human-type glycoprotein having reduced glycosylation by genetically manipulating an enzyme involved in glycosylation using a Hansenula polymorpha system. In detail, the present invention relates to a process for producing a human-type glycoprotein by identifying a dolichyl-phosphate-mannose dependent ¥á-1,3-mannosyltransferase gene from H. polymorpha, constructing a H. polymorpha mutant strain producing a glycoprotein exhibiting reduced glycosylation by disrupting the identified gene, and subjecting the mutant strain to various genetic manipulations for the synthesis of human-type glycan.

  • Patent number: 7565138
    Abstract: A method for managing information on user equipments (UEs) in a mobile communication system supporting an MBMS (Multimedia Broadcast/Multicast Service) service. A radio network controller (RNC) provides a packet switched (PS) service and a circuit switched (CS) service to the UEs. A UE that is in a Packet Mobility Management-Idle (PMM-Idle) mode after joining at least one MBMS service, transmits MBMS service-related information thereof to the RNC, and the RNC stores the MBMS service-related information in a first service context for the MBMS service held in the RNC, together with information on the UE.

  • Publication number: 20090093243
    Abstract: A radio link (RL) parameter updating method of a high speed downlink packet access (HSDPA) system in a mobile communication system is disclosed. According to a radio channel situation of a terminal, an RL parameter applied to transmission and reception of control information between the terminal and a base station is dynamically controlled. For this purpose, the RL parameter updating method includes: a step in which the base station determines whether to update an HSDPA related parameter and transmits the parameter update information to the RNC to trigger updating of the RL parameter; and a step in which the RNC updates the HSDPA related parameter and transmits it to the terminal. The parameter update information is delivered through an RL parameter update response message, and the RNC is a serving RNC.

  • Patent number: 7447515
    Abstract: An apparatus and method for transmitting a control signal using a symbol or bit pattern of an existing pilot channel, instead of using the time multiplexing method in the separate code channel or the existing physical channel, and reducing an error rate while a reception side detects the control signal are provided. For that purpose, a transmission side allocates transmission power corresponding to a pilot pattern determined according to the control information. A corresponding reception side detects control information based on a pilot pattern of pilot bits inserted in a dedicated physical channel (DPCH) and generates transmit power control (TPC) bits referring to a target reception power which is set based on the control information.

  • Patent number: 7315509
    Abstract: A method for enabling a user equipment (UE) to recover from a multimedia broadcast/multicast service (MBMS) data error in a mobile communication system. The mobile communication system includes a radio network controller (RNC) and at least one cell for transmitting MBMS data to at least one UE according to a control operation of the RNC. The RNC transmits first control information to UEs located in each cell. Each of the UEs receives the first control information and the MBMS data. When an error in the received MBMS data is detected, the RNC is notified that an MBMS data reception error has occurred. Response information associated with the MBMS data reception error is transmitted from the UE to the RNC. The UE determines whether control information contained in the response information matches the first control information. The MBMS data reception error is recovered from, according to a result of the determination.

  • Patent number: 7162241
    Abstract: A multicast service of a 3GPP Universal Mobile Telecommunications System (UMTS) is disclosed. By allowing an RNC to manage multicast group member information by multicast services on multicast areas, when a user terminal being currently provided with an MBMS service moves, the RNC sends information on the movement of the terminal to a core network. Since the RNC notifies the core network of the terminal's movement selectively on the basis of the multicast group member information by multicast services on the multicast area, the network resource can be effectively used, and especially, unnecessary transmission of terminal's movement information from the RNC to the multicast group managing entity of the core network can be prevented.

  • Publication number: 20050282569
    Abstract: An apparatus in a mobile communication system for providing a multimedia broadcast/multicast service (MBMS) and a method for giving notification of an MBMS service while considering transmission mode are provided. A controlling radio network controller (CRNC) sends, to a serving radio network controller (SRNC), transmission mode information indicating point-to-point (PTP), point-to-multipoint (PTM), or “Not provide” cell by cell. The SRNC determines service notification on the basis of the transmission mode information. The CRNC minimizes a signaling load on an Iur interface when sending, to the SRNC, the transmission mode information suitable for each cell.
