A connecting wireless device and an established wireless device both utilize low power transmission at close proximity to exchange wireless connection setting information and/or a password. The connecting wireless device is moved into proximity with the established wireless device and a low power setting is discovered at which the wireless devices may communicate with a sufficiently low error rate. The proximity of the connecting wireless device to the established wireless device is verified and the connecting wireless device is then passed the secret information by the established network device.Type: ApplicationFiled: December 8, 2006Publication date: April 12, 2007Applicant: Microsoft CorporationInventors: Poovanpilli Madhavan, David Roberts, Mohammad Alam, Zhong Deng, Sharad Mittal, Ankur Agiwal

Publication number: 20070081509Abstract: A method and a system for controlling a reverse link rate by using the number of active users who are carrying out communication in a CDMA 1xEV-DO mobile communication system is disclosed. A value of rise-over-thermal (ROT) at each antenna end of a wireless base station is measured and compared with a threshold ROT which defines an allowable limit of the ROT. A reverse activation control bit is set as 0 if the measured ROT value is smaller than or equal to the threshold ROT. The number of the active users is compared with a threshold user number which defines an allowable limit of the active users if the measured ROT value is greater than the threshold ROT. The reverse activation control bit is set as 0 if the number of the active users is smaller than or equal to the threshold user number. The reverse activation control bit is set as 1 if the number of the active users is greater than the threshold user number.Type: ApplicationFiled: July 30, 2004Publication date: April 12, 2007Applicant: SK Telecom Co., Ltd.Inventors: Jongtae Ihm, Jaemoon Lee, Hojin Yang, Jintae Choi, Sungho Jo, Sangjin Han

Publication number: 20070081510Abstract: In a packet-based communication network (10) polling of connected user equipment is performed according to a first type (T1) and a complementary second type (T2). Upon receiving polling according to type one (T1) a user equipment (30) is allowed to transmit user data packets (UP) if any are available, otherwise the user equipment (30) can remain silent. In response to polling according to type two (T2), the user equipment (30) is required to either transmit an available user data packet (UP) or a dummy data packet (DP).Type: ApplicationFiled: October 23, 2003Publication date: April 12, 2007Inventors: David Bladsjo, Erik Westerberg

Publication number: 20070081512Abstract: By assigning a fixed home address to an MN, Mobile IPv6 assures the arrival of each content at the MN 1. In order to allow the user to receive a Mobile IPv6 service, it is necessary to provide the MN 1 with a Mobile IPv6 function for making applications conform to IPv6. However, there are only few such MNs 1. In addition, the MN 1 does not have a function for implementing an IPsec process repeatedly on a packet transmitted to and received from another apparatus. A scenario processing port 23 employed in the MN 1 includes a means, which is used for selecting a process according to a communication method and carrying out the selected process when a response to a Mobile IPv6 location registration message is received. By providing the scenario processing port 23 with a means for selecting a communication method, a function can be added to the MN 1 with ease.Type: ApplicationFiled: July 7, 2004Publication date: April 12, 2007Inventors: Yukiko Takeda, Takehiro Morishige, Hidenori Inouchi, Yusuke Hara

Publication number: 20070081513Abstract: A data communication having at least one data flow is established over a wireless interface between a radio network and a user equipment node (UE). A medium access control (MAC) layer located in a radio network node receives data units from a higher radio link control (RLC) layer located in another radio network node. Some or all of a header of a RLC data units associated with the one data flow is analyzed at the MAC layer. Based on that analysis, the MAC layer determines a priority of the data unit relative to other data units associated with the one data flow. The MAC layer schedules transmission of higher priority data units associated with the one data flow before lower priority data units associated with the one data flow. The priority determination does not require extra priority flags or signaling.Type: ApplicationFiled: October 7, 2004Publication date: April 12, 2007Inventor: Johan Torsner

Publication number: 20070081514Abstract: A timing master device transmits a timing packet for synchronizing time of base stations at each cycle of preset time synchronization adjustment timing. The base stations adjust a local-station standard timer based on the timing packet. The base stations measure a delay time of a network form the timing master device to a local station, and adjust the local-station standard timer based on the measured delay time.Type: ApplicationFiled: June 25, 2004Publication date: April 12, 2007Inventors: Yoshihiko Shirokura, Toshiaki Tomisawa

Publication number: 20070081515Abstract: The invention provides a router which can be deployed in a network on an integrated circuit. The router is capable of processing input data belonging to multiple traffic classes. The router can further guarantee, under admissible traffic, that all input data are processed and output adequately at an acceptable cost. The invention relies on the perception that the problem of contention is constituted by two more specific problems: input contention and output contention. The problem of input contention does not occur anymore, because the switch comprised in the router is designed such that it can serve multiple queues coupled to input ports simultaneously. The problem of starvation, caused by a continuous preference of high priority traffic to low priority traffic, is solved by allowing to serve queues containing data from low priority traffic classes simultaneously with queues containing data from high priority traffic classes.Type: ApplicationFiled: October 20, 2004Publication date: April 12, 2007Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Johannus Theodorus Matheus Dielissen, Edwin Rijpkema
