Patent number: 7787444Abstract: A method and mobile terminal are disclosed for use in a wireless communication system in order for the mobile terminal to be able to transition from a dual mode, in which a packet switched connection and circuit switched connection are used together, to a single mode in which packets are transferred. The mobile terminal is for receiving minimum system information necessary to perform the transition in an uninterrupted manner, instead of an interrupted manner. This system information is broadcast to the mobile terminal on a regular basis, and is also sent to the mobile terminal partly or entirely by point-to-point transfer if a piece of the minimum system information is missing due to inadequate broadcast reception or some other reason. This system information is then employed by the mobile terminal to transition from the dual mode to the single mode in the uninterrupted manner.Type: GrantFiled: January 5, 2006Date of Patent: August 31, 2010Assignee: QUALCOMM IncorporatedInventors: Rami Vaittinen, Antti O.

Patent number: 7684357Abstract: A system and method for reducing idle mode power consumption for mobile stations (MS) that have joined a Multimedia Broadcast/Multicast Service (MBMS) session and are waiting for the session to start. The invention is also directed to reducing the power consumption of an MS for which an MBMS session is inactive. In alternative aspects of the invention, the power consumption of mobile stations is reduced in the absence of ongoing MBMS session activity. Reduced power consumption is achieved by eliminating the need to read notification messages from an MBMS specific notification paging group when the notification message is for a different MBMS session than the paging group that the MS has currently joined.Type: GrantFiled: September 14, 2005Date of Patent: March 23, 2010Assignee: Nokia CorporationInventors: Harri Jokinen, Guillaume Sebire, Rami Vaittinen

Patent number: 7623885Abstract: Controlling the output power level of a dual transfer mode (DTM) capable terminal involves generating a network message. The network message may be a circuit-switched (CS) handover command and/or a point-to-point signaling message. A maximum output power level value is associated with the network message. The network message is transferred from the network to the terminal. A packet-switched (PS) output power level of the terminal is determined using the maximum output power level value received via the network message.Type: GrantFiled: September 22, 2004Date of Patent: November 24, 2009Assignee: Nokia CorporationInventors: Rami Vaittinen, Harri Jokinen

Patent number: 7623509Abstract: A method and terminal are disclosed for use in a wireless communication system, in order for the terminal to transition from a dual mode, in which a packet switched connection and circuit switched connection are used, to a single mode in which packets are transferred. The mobile terminal is for receiving minimum system information necessary to perform this transition in an uninterrupted manner. This system information is sent to the mobile terminal automatically or on a regular basis, and is additionally sent to the mobile terminal partly upon request of the mobile terminal. A release indication is sent to the terminal separately from the system information, notifying the terminal that the circuit switched connection will be released, at which point a timer is started. The system information is employed by the mobile terminal to transition from the dual mode in the uninterrupted manner, if the timer has not expired.Type: GrantFiled: June 14, 2004Date of Patent: November 24, 2009Assignee: Nokia CorporationInventors: Rami Vaittinen, Antti O.

Patent number: 7519384Abstract: A system and method for minimizing the gap in service during the reception of an MBMS session due to the reselection of a neighboring cell in which that MBMS session is not ongoing, wherein a mobile station (MS) indicates its target cell and MBMS service id (i.e., BSIC, neighboring cell index, and Temporary MBMS Group Identity (TMGI)) to a network by sending this information to the network in an RLC/MAC message, e.g., a packet downlink ACK/NACK or with a new message. If the network has resources available for allocation, the network is permitted to allocate these resources for the MBMS session indicated by the MS and send corresponding MBMS neighbor cell information to the MS upon receipt of the packet downlink ACK/NACK or the new message. When the MS receives the MBMS neighbor cell information, it will then reselect to the target cell identified by the MBMS neighbor cell information.Type: GrantFiled: August 17, 2005Date of Patent: April 14, 2009Assignee: Nokia CorporationInventors: Rami Vaittinen, Harri Jokinen, Guillaume Sebire
