    摘要: A method performed by a system (120) for determining a position of a device (140) connected to a communication network (100) is disclosed. The method comprises obtaining a geographical area for the device based on a first position-estimation service, obtaining information on luminosity on the device over a time period, and determining a second position estimation for the device (140) based on the geographical area and on the information on luminosity, by comparing the information on luminosity over the time period to a 3D model of the geographical area, the 3D model comprising models of 3D objects of the geographical area and a model of sunlight shining onto the models of the 3D objects over the time period. Disclosed is further a corresponding system and a position-determining method performed by a communication device.

    摘要: A wireless device and a method for providing an improved cell reselection procedure. The wireless device is served in a serving cell. At a first point in time, the wireless device determines a first signal quality of a first signal received from the serving cell. At a second point in time, it determines a second signal quality of a second signal received from a neighbour cell. Based on the determined first and second signal qualities, the wireless device determines a first trigger condition for performing measurements for cell reselection. At a third point in time, the wireless device determines a third signal quality of a third signal received from the serving cell. When a difference between the third and first signal qualities has passed the trigger condition, the wireless device performs at least one measurement for cell reselection on at least one of the cells.

    摘要: A wireless device 204 and a method for providing an improved cell reselection procedure. The wireless device is served in a serving cell 212-1. At a first point in time, the wireless device determines a first signal quality of a first signal received from the serving cell. At a second point in time, it determines a second signal quality of a second signal received from a neighbour cell 212-2, 222, 232. Based on the determined first and second signal qualities, the wireless device determines a first trigger condition for performing measurements for cell reselection. At a third point in time, the wireless device determines a third signal quality of a third signal received from the serving cell. When a difference between the third and first signal qualities has passed the trigger condition, the wireless device performs at least one measurement for cell reselection on at least one of the cells.
