20150078359 | ACCESS POINT DETECTION - A wireless communications device has network interfaces for accessing cellular data networks and Wi-Fi wireless local area networks. Wi-Fi offload allows data traffic to be moved away from the cellular network to the Wi-Fi network. To avoid any existing data sessions being broken during offload, Proxy Mobile IP (PMIP) must be supported by a Wi-Fi access point and associated Mobile Access Gateway. After Wi-Fi association and authentication, the wireless communication device probes the access point and MAG to determine whether PMIP is supported. | 2015-03-19 |
20150078360 | Network Access Method And Apparatus - The embodiment of the present invention discloses a network access method and apparatus. The method comprises: a UE receiving WLAN access auxiliary information sent by a 3GPP access network; according to the information, the UE measuring WLAN radio signal quality and performing an access judgment to obtain a judgment result; and the UE accessing to the WLAN according to the judgment result. The present invention can accelerate the access of the UE to the WLAN and enable the UE to acquire subsequent data joint transmission and/or services, thereby improving the user experience. | 2015-03-19 |
20150078361 | RADIO NETWORK FOR SUPPORTING FARMING OPERATIONS - A farm irrigation network includes an irrigation assembly having a radio, a soil moisture sensor assembly having a radio, and a sub-master site having a first radio and a second radio. The first radio and the radios of the irrigation assembly and the soil moisture assembly form a local network and the second radio is configured to communicate with a backhaul medium to establish communications with a server. | 2015-03-19 |
20150078362 | COMMUNICATION SYSTEM AND COMMUNICATION METHOD - In the present invention, a connection controller controls opening/closing of connection between a first communication unit that communicates with a terminal device and a second communication unit that communicates via a network. A connection setting unit instructs opening/closing of the connection to the connection controller in accordance with a user input received by an input unit in accordance with first identification information output from the terminal device displayed on a display unit. | 2015-03-19 |
20150078363 | WIRELESS COMMUNICATOR FOR LAPTOP COMPUTERS - A cellular communicator, including a baseband modem for connecting to the Internet via a cellular network and an Internet gateway, and a wireless modem, for connecting to a computer modem via a short range wireless communication, and for providing the computer modem with Internet access via the baseband modem. | 2015-03-19 |
20150078364 | System and Method for Online Sign Up Provider Selection - A mobile station selects a provider such as an online sign up (OSU) provider by receiving a pre-association message including OSU selection information from a Wi-Fi network component, such as an access point in communication with the OSU provider, and sending a selection of an OSU provider in accordance with the OSU selection information to the network component. The OSU selection information excludes identification of the OSU network provider or resource, but provides other attributes to the user, such as price or service configuration. The pre-association message may be transmitted as a beacon or using ANQP. | 2015-03-19 |
20150078365 | VIRTUAL ACCESS POINT USING SINGLE SERVICE SET IDENTIFIERS - An Access Point (“AP”) apparatus comprising one or more processors containing program code. The program code may be configured to: (i) cause the AP to broadcast a beacon containing a single SSID indentifying the AP; (ii) cause the AP to receive from the STA an query for network information for at least one network operator accessible through the AP; and (iii) cause the AP to send to the STA, for the at least one network operator, a network information description element, in response to the network information query. The AP providing the plural responses broadcasts only a single service set identification (“SSID”). | 2015-03-19 |
20150078366 | MULTI-CARRIER CONFIGURATION, ACTIVATION AND SCHEDULING - Embodiments of block acknowledgements request apparatus, systems, and methods are generally described herein. Other embodiments may be described and claimed. An aggregated block of a plurality of data frames is received from an originator transmission, with each data frame including a medium access control (MAC) header. An acknowledgement policy that is solicited by the originator is identified in a quality of service field in at least one of the MAC headers of the received transmission. A single block acknowledgement is transmitted to the originator acknowledging receipt of one or more of the plurality of data frames in the aggregated block of data frames. | 2015-03-19 |
20150078367 | COMMUNICATIONS DEVICE, COMPUTER PRODUCT, AND COMMUNICATION CONTROL METHOD - A communications device includes a processor configured to detect a wirelessly communicating base station, using a given interval; determine whether identification information of the detected base station matches identification information of a base station detected last time; and set the given interval to a second interval upon determining that the identification information of the detected base station and the identification information of the base station detected last time match. The second interval is longer than a first interval that is set upon determining that the identification information of the detected base station and the identification information of the base station detected last time do not match. | 2015-03-19 |
