A mobile content delivery system that optimizes the delivery of especially bandwidth-consuming content (or the flow of any peak-hour data traffic) in a way that best utilizes the free capacity in the radio network, thus enabling considerably more efficient usage of the radio capacity. It also allows new services and pricing structures to be used in the cellular network, that otherwise would not be possible. The class of delivery of message content can be selected by the user on a transaction basis, or subscription-based and pre-defined in a user profile. By choosing a scheduled delivery the user can receive the content at a fraction of the price compared to instant delivery, since the content is sent at a time when the network is least utilized.

System(s) and method(s) for compensation of propagation delay offsets of wireless signals. Compensation is accomplished through determination of an effective wireless signal propagation delay that accounts for signal path delay and propagation delay over the air. Such determination is based at least in part on statistical analysis of accurate location estimates of reference positions throughout a coverage sector or cell, and location estimates of the reference positions generated through time-of-flight (TOF) measurements of wireless signals. Determination of propagation or signal path delay offset also is attained iteratively based at least in part on reference location estimates and TOF location estimates. High-accuracy location estimates such as those obtained through global navigation satellite systems are employed as reference location estimates. Position of probes or wireless beacons, deployed throughout a sector or cell, also are employed as reference locations. Compensation of propagation delay offset improves accuracy of conventional TOF location estimates and radio network performance.

Conversely, when the load condition is relieved, the second RAN node can request that the first RAN node increase the transmission rate of information. The rate control may be applied in both downlink and uplink directions.

The present invention relates to prioritizing special cells in cell selection in a cellular radio network. In a cellular radio network one or more cells provide a subscriber with special services or tariffs not offered to all subscribers. These cells are called subscriber's special cells. The mobile station measures an average reception level and calculates by means of them cell selection parameters on the basis of which the best cell is selected. In accordance with the invention, when the mobile station detects that the cell is one of cells of a special cell list stored in a memory, it checks first if the cell fulfils a minimum requirement of cell selection on the basis of the measured signal level. If the minimum requirement is fulfilled, the mobile station manipulates the calculation of the cell selection parameter of a special cell to the effect that the selection probability of a special cell is improved with respect to a normal cell. In a preferred embodiment of the invention, the manipulation of the calculation comprises a step of adding a predetermined margin to the measured signal level of a special cell before the cell selection parameter is calculated. This will minimize the possibility that the mobile station would accidentally be camped on a normal cell when it is within the area of a special cell.
