20110310793 | ON-DEMAND INFORMATION RETRIEVAL USING WIRELESS COMMUNICATION DEVICES - A method, information processing system, and computer program product provide on-demand information captured from wireless devices. An information request is received from an electronic device. At least one wireless communication device is identified from a set of wireless communication devices that is available to satisfy the information request. The information request is sent to the at least one wireless communication device in response to identifying the at least one wireless communication device. A set of information is received from the at least one wireless communication device that satisfies the information request. The set of information that has been received is sent to the electronic device. The information request comprises a request for a set of information of at least one information type and from a given geographical location. | 2011-12-22 |
20110310794 | METHODS OF PROVIDING PAGES INCLUDING CALLING PARTY NUMBER USING A TUNNELING PROTOCOL - A page including a calling party number from a circuit-switched network may be provided to a wireless terminal in wireless communication with a packet-data network. More particularly, a call origination message may be received at the circuit-switched network for the wireless terminal with the call origination message including a calling party number. Responsive to receiving the call origination message at the circuit-switched network, a Generic Circuit Services Notification Application (GCSNA) message may be generated at the circuit-switched network, and the GCSNA message may include a page message and the calling party number. The GCSNA message including the page message and the calling party number may then be transmitted to the wireless terminal through the packet-data network using a GCSNA tunneling protocol. Related methods, terminals and networks are also discussed. | 2011-12-22 |

20110310796 | DISPLAY APPARATUS AND METHOD FOR CONNECTING TO VIDEO CALL THEREOF - Embodiments relates to a display apparatus that can perform a video call and a method of connecting to a video call thereof, in which the method includes: receiving a control signal from an external device where an identification information for a video call is registered when a video call is received; turning on the display apparatus in response to the received control signal; and connecting to the received video call. | 2011-12-22 |
20110310797 | Packet retransmission control apparatus and packet retransmission controlling method - The present invention provides a packet retransmission control technique in which the communication performance can be improved in a state that the load of a network is high. The packet retransmission control apparatus includes a priority determining section configured to set a packet kind to each of transmission packets to indicate a kind of the transmission packet, and determine a priority level based on the packet kind to indicate an transmission order of the transmission packets; a packet buffer comprising a plurality of queues respectively assigned with priority levels, and configure to store the transmission packet in one of the plurality of queues which is determined based on the priority level of the transmission packet; and an arbitrating section configured to output the transmission packets from one assigned with the highest priority level of the plurality of queues to a lower layer in order of higher priority level. | 2011-12-22 |
