Abstract: The document specifies a method for determining field strength which can be used in mobile radio systems, such as Bluetooth. The principle proposed involves alternate transmission and reception in the mobile radio system, with each timeslot comprising at least one time interval for transmitting/receiving a data block (RX, TX). The reception field strength (RSSI) is measured directly before (A, B) or directly after (C, D) transmission or reception of the data block (RX, TX). This allows the number of locking operations required in a PLL to be reduced and still allows adaptive channel adjustment to be performed, for example in a “frequency hopping method”, by measuring all channels without reducing the net data rate.

Abstract: Methods, apparatuses, and systems directed to a wireless node location mechanism that uses a signal strength weighting metric to improve the accuracy of estimating the location of a wireless node based on signals detected among a plurality of radio transceivers. In certain implementations, the wireless node location mechanism further incorporates a differential signal strength metric to reduce the errors caused by variations in wireless node transmit power, errors in signal strength detection, and/or direction-dependent path loss. As opposed to using the absolute signal strength or power of an RF signal transmitted by a wireless node, implementations of the present invention compare the differences between signal strength values detected at various pairs of radio receivers to corresponding differences characterized in a model of the RF environment.

Abstract: An access network controller and a base station controller are formed to define an interface there between that enables the two systems to facilitate and respond to a voice call that is to be set up to a hybrid mobile station even though the hybrid mobile station is presently engaged in a data only call. More specifically, the base station is formed to generate a pseudo-page signal to the access network controller to determine whether the hybrid mobile station is present and available prior to the base station generating paging signals to establish the voice call. According to the response received from the access network controller, the base station either pages the hybrid mobile station to establish the voice call, forwards the call to voice mail, or forwards the call either to an Internet Call Delivery Server or to an Internet Call-Waiting Server.

Abstract: A radio antenna of a radio base station is a directional antenna. The antenna searches for a peripheral radio base station by changing the directivity of the antenna. An operating channel and electric field intensity of the other base station are acquired by the searching and then stored as positional information. The operating channel of the base station, the directivity of the antenna, and a radio wave intensity communication area are set according to the acquired positional information. Further, the positional information is transmitted and received to and from the other base station to set the base station. When the base station was moved or when external noise occurred abruptly, channel change and change of a cell shape of the directional antenna are carried out. Consequently, interference between the base stations can be minimized and optimum setting of the channel and communicatable area can be realized.
