A mobile terminal device that facilitates location services (LCS) in a cellular network. The system, as embodied in a mobile terminal device, comprises a mobile communications component that communicates wireless signals, and a location services component embodied in the mobile communication component to provide positioning information. A location request is received by the mobile terminal device and processed using the LCS server to activate trigger events. A location-tracking report is autonomously generated for each event and transmitted to the requesting client via MLP or the wireless network signaling protocol.

A TDMA wireless communication system adjusts the power control target and transmission power based upon link quality to enhance voice capacity. The power can be adjusted in response to the average SNIR and number of decoding errors in a link quality reporting period. The power control target can be increased and decreased in discrete intervals after evaluating the number of decoding errors in the reporting period. The transmission power can be adjusted towards the new power control target based upon the average SNIR.
