20150023180 | METHOD AND APPARATUS FOR OBTAINING TERMINAL MINIMIZATION OF DRIVE-TESTS DATA - The present invention discloses a method and an apparatus for obtaining terminal minimization of drive-tests data, relates to the field of communication technologies, and solves a problem that when determining, according to minimization of drive-tests (MDT) data, that a current operating status of a network is abnormal, an operation, maintenance and administration (OAM) cannot accurately determine whether the abnormality of the network is caused by a terminal or the network itself since the MDT data received by the OAM does not include an identity of the terminal. The method includes: obtaining MDT data measured by a terminal and an identity of the terminal; and reporting the MDT data measured by the terminal and the identity of the terminal to an OAM. Embodiments of the present invention are mainly applied to a process of obtaining terminal minimization of drive-tests data. | 2015-01-22 |
20150023181 | WIRELESS COMMUNICATION DEVICE THAT IS CAPABLE OF IMPROVING DATA TRANSMISSION EFFICIENCY, ASSOCIATED NETWORK, AND METHOD - A wireless communication device includes a data transmission and reception section that wirelessly transmits a plurality of test packets; a signal sensing section that senses a power of a spatial radio wave signal on a frequency channel that is the same as the plurality of test packets and outputs sample data of the sensed spatial radio wave signal; a calculation processing section that converts the sample data into time series sample data; a collision detection section that calculates a packet collision rate based on the number of packet collisions and the number of the plurality of test packets if there is a packet collision due to interference of the plurality of test packets with another communication; and a control section that adjusts a parameter that the data transmission and reception section uses based on a calculation result of the collision detection section. | 2015-01-22 |
20150023182 | Communication System, Transmission Apparatus, Line Control Apparatus, Line State Monitoring Method and Non-transitory Computer Readable Medium Storing Program - A communication system includes a radio transmission apparatus that terminates a radio communication line, a radio transmission apparatus that terminates a radio communication line, and a line control apparatus that performs data communication with the radio transmission apparatuses. The radio transmission apparatuses and monitor the line states of the radio communication lines and notify the line control apparatus of the line states. The line control apparatus controls data to be output to the radio transmission apparatuses and according to the line states. | 2015-01-22 |
20150023183 | USING DISCOVERABLE PEER-TO-PEER SERVICES TO ALLOW REMOTE ONBOARDING OF HEADLESS DEVICES OVER A WI-FI NETWORK - The disclosure relates to using discoverable peer-to-peer (P2P) services to remotely “onboard” headless devices over a Wi-Fi network. In particular, an onboardee device may enter an onboarding mode in which the onboardee device becomes a Wi-Fi access point (AP) and an onboarder device connected to a private Wi-Fi network may discover the onboardee device and establish a secured session to engage with the P2P services running thereon. The first time that the onboarder device and the onboardee device engage with one another, the secured session may be established based on a key exchange that uses a well-known secret (e.g., a default passphrase), which may be immediately changed to a shared secret. The onboarder device may then transfer an onboarding configuration to the onboardee device, which may be instructed to validate the onboarding configuration and connect to the Wi-Fi network prior to entering the connected mode. | 2015-01-22 |
