摘要： Power saving operation of user equipment in a cellular communication system. Mobile User Equipment UE is operated in a first mode in which radio functions are enabled. In response to a predetermined condition, the UE is operated in a power saving mode involving disabling all radio functionality for a first period of time during which no connection is maintained with a cellular communication system serving node. After the first period of time, the UE ascertains (305) whether any attempts were made to contact it during the first period of time and if so (307) whether any of the attempted contacts is characterized by an attribute that matches a predefined attribute. If any of the attempted contacts is characterized by the attribute that matches the predefined attribute, then a user alarm is activated (309). If the response to the user alarm has been made (311), then the UE is again operated in the first mode (313); otherwise, the UE is again operated in the power saving mode (315).

摘要： The automatic frequency correction value applied by a receiver is altered to minimize long-term drift of a path delay profile. In one embodiment, the phase or timing error resulting from constant frequency corrections is accumulated, and an estimated frequency correction value is selectively quantized into an actual frequency correction value in response to the accumulated phase/timing error. The quantized value above or below the estimate is selected to minimize the accumulated phase/timing error that gives rise to path delay profile drift. In another embodiment, a timing circuit measures the instantaneous path delay profile drift incurred with each frequency correction, and integrates the instantaneous drift measurements over time to yield a path delay profile drift. The drift (or its rate of change) is then used to adjust a frequency correction value so as to minimize the drift.

The wireless communication system (100) comprises one or more Long-Term Evolution, LTE, networks (120) and one or more 2nd or 3rd Generation, 2G/3G, networks (130). When the communication device (110) is camping in an LTE network (120) and starts a Circuit Switched, CS, service, the wireless communication device (110) sends a CSFB request to a Mobility Management entity, MME (122), via an access node (124) in the LTE network (120) and starts a first timer and/or a first counter upon sending the CSFB request. When the first timer and/or the first counter is expired and no response to the CSFB request has been received from the LTE networks, it starts a cell search procedure in the 2G/3G networks (130 and starts the CS service via a target cell selected by the cell search procedure in the 2G/3G networks.

摘要： A method in a communication device (110) for providing a location information of the communication device (110) to a Minimization of Driving Tests, MDT, server (125) is disclosed. The communication device operates in a wireless communication environment (100) which comprises multiple networks comprising at least one cellular network (120) and at least one satellite positioning system (130). The communication device (110) starts an MDT measurement and determines a signal strength received from a satellite (132) in the satellite positioning system (130) by measuring the signal strength at a positioning antenna. When the signal strength received from the satellite (132) is above a threshold, the communication device 110 determines a feasibility of an Assisted Global Position System, AGPS. When the AGPS is feasible, the communication device 110 initiates an AGPS session for obtaining the location information using an acquisition assistance data and sends the location information together with other MDT data to the MDT server.
