20090099374 | METHOD FOR PRODUCING FLAVAN DERIVATIVE - The present invention provides a method for producing flavan derivatives having various substituent groups with controlling the stereochemistry. The method of the present invention includes the steps of: hydratively condensing a phenol compound expressed by formula (I) and an alcohol compound expressed by formula (II) to from an epoxide compound of formula (III); opening the epoxy ring of the epoxide compound of formula (III) to form an iodine-containing compound of formula (IV); and cyclizing the iodine-containing compound to form the flavan derivative of formula (V). | 04-16-2009 |
20110124355 | COMMUNICATION METHOD, MOBILE TERMINAL, SWITCHING DEVICE, AND RADIO CONTROL DEVICE - A communication method according to the present invention includes: transmitting, at a radio base station device (b), broadcast information for notifying a first area and a second area; transmitting, from a first mobile terminal to a radio control device (c), a first location registration request signal for the first area included in the broadcast information, when the first area is not identical to a first area stored as a current location registration area; and transmitting, from a second mobile terminal to the radio control device (c), a second location registration request signal for the second area included in the broadcast information, when the second area is not included in a second area group stored as a current location registration area. | 05-26-2011 |
20110176413 | MOBILE COMMUNICATION METHOD, NETWORK DEVICE, AND EXCHANGE - Provided is a mobile communication method which includes: a step in which a first exchange station MME#a allocates a temporary identifier TMSI for identifying a mobile station UE# | 07-21-2011 |
20110177812 | MOBILE COMMUNICATION METHOD AND MOBILE STATION - In a mobile communication method, when a mobile station UE has moved from an area inside UTRAN to an area inside E-UTRAN, a connection process with “Default APN” is executed if no connection with the “Default APN” is established even if it is determined that no position registration process need to be executed for the E-UTRAN. | 07-21-2011 |
20130012243 | MOBILE COMMUNICATION METHOD, CALL CONTROL NODE, PRIORITY CONTROL NODE AND MOBILITY MANAGEMENT NODE - The present invention provides the steps of: at a priority control node (PCRF), when reception of an invite signal including priority call information is notified from a call control node (P-CSCF), determining whether it is required to change the ARP of a call control signal bearer for sending the invite signal from a gateway (P-GW) to a mobile terminal (UE) to a higher ARP than the priority set in the call control signal bearer; when change of the ARP is determined to be required, changing the ARP of the call control signal bearer to a higher ARP than the ARP set in the call control signal bearer; and performing a paging for the mobile terminal (UE) according to the priority of the call control signal bearer. | 01-10-2013 |
20130170438 | PAGING METHOD, CORE NETWORK APPARATUS, RADIO ACCESS NETWORK APPARATUS AND GATEWAY APPARATUS - A paging method of the present invention is a paging method for paging a UE ( | 07-04-2013 |
20130343325 | MOBILE COMMUNICATION METHOD - A mobile communication method according to an embodiment of the invention includes: a step A of causing a S-GW# | 12-26-2013 |
20140254363 | MOBILE COMMUNICATION METHOD, MOBILITY MANAGEMENT NODE, PACKET SWITCH, AND MOBILE STATION - Even if a failure has occurred in core network equipment in a state in which bearers are established between a large number of UEs and a packet data network, congestion in the network is avoided. A mobile communication method according to the present invention includes steps of transmitting, by an MME, to transmit a “PDN Disconnection Request/Detach Request” including barring time to a UE when the MME disconnects a bearer between the UE and the packet data network due to a predetermined reason such as a failure in a S-GW/P-GW or the MME in a state in which the bearer is established, and barring, by the UE, a mobile originating call directed to the packet data network for the barring time. | 09-11-2014 |
