Abstract: Techniques for supporting location services are disclosed. In an aspect, a generic location session between a terminal and a location server may be established for a particular duration or until the generic location session is terminated by a trigger condition. Parameters related to the generic location session may be exchanged between the terminal and the location server during session establishment. Thereafter, the terminal and the location server may engage in one or more positioning activities at any time during the generic location session. Each positioning activity may be of any type supported by the terminal and the location server. The generic location session can be initiated by either the terminal or the location server. In one design, one entity (e.g., the location server) may initiate the generic location session, and the other entity (e.g., the terminal) may send an end message to terminate the generic location session.

Abstract: Systems and methods for detecting a Line of Sight (LOS) in a cellular communications network are provided. In one embodiment, a network node in the cellular communications network determines whether a wireless device is within LOS of a base station. In order do so, the network node compares a Ricean factor of a wireless communications channel between the base station and the wireless device and a predetermined Ricean factor threshold for LOS detection. In addition, the network node compares a Root Mean Squared Error (RMSE) between a Rayleigh probability density function and samples of received signal strength for radio signals transmitted between the base station and the wireless device and a predetermined RMSE threshold for LOS detection. The network node then determines whether the wireless device is within LOS of the base station based on results of the comparisons.

Abstract: Embodiments describe registration in a wireless communication system. A method includes wirelessly transmitting over a WWAN a first registration message from a mobile device, wirelessly transmitting through the WWAN a second registration message to a WLAN access point and receiving at the mobile device access through the WLAN access point. According to another embodiment is a method for constructing a self-configuring ad-hoc network. The method can include receiving a GPS coordinate from a WWAN channel node at a management system and creating an initial topography based at least in part on the GPS coordinate to achieve a network connectivity with diverse routes between a plurality of nodes.

Abstract: A method of providing a location based service to an access terminal in a mobile communication system is provided. The method includes transmitting one or more access probes, each of the one or more access probes including a preamble having a first specific length and transmitted at a first power level, where the preamble is utilized to determine a position of the access terminal.

Abstract: The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.
