Abstract:
1. A method for adjusting resource management procedures in a mobile device communicating with a node operating in a cell in a heterogeneous communication network, the method comprising: receiving a signal, including a reference signal, transmitted from the node during a predetermined time period; measuring signal reception information at predetermined time intervals during the predetermined time period, wherein said signal reception information includes reference signal power values and one or more of reference signal quality values and signal to interference plus noise ratio values; measuring speeds of movement of the mobile device at said predetermined time intervals; determining a reference signal power variation value based on the variability of the measured reference signal power values; comparing the determined reference signal power variation value with a predetermined power threshold value for a given measured speed; determining cell information based on the comparison; determining an adjustment to a resource management procedure based on the determined cell information; adjusting the resource management procedure based on the determined adjustment; determining one or more of a reference signal quality variation value based on the variability of the measured reference signal quality values and a signal to interference plus noise ratio variation value based on the variability of the measured signal to interference plus noise ratio values; and comparing one or more of the determined reference signal quality variation value with a predetermined quality threshold value for a given speed and the determined signal to interference plus noise ratio variation value with a predetermined signal to interference plus noise ratio threshold value for a given speed; wherein determining the cell information is based on the comparisons for reference signal power and one or more of reference signal quality and signal to interference plus noise ratio variations.
