摘要： The idea of the invention is the allocation of transmission resources in several separate steps. In the first step, the available transmission resources are dynamically divided between the different networks. In the second step, the networks divide the resources that have been allocated for their use among their users by their own channel allocation methods. In one embodiment, a given minimum capacity wherewith the network achieves a predetermined minimum quality of service is permanently allocated to some or all of the networks. As the capacity requirement increases, the necessary amount of additional capacity is allocated to the operator in excess of this minimum capacity. The additional capacity is then allocated either from resources separately reserved for this purpose that are common to the networks, or by borrowing it from capacity that is allocated to another network but falls outside the minimum capacity of said network. In accordance with one embodiment, an upper limit is set for the transmission capacity allocated to a network, in excess of which no capacity can be allocated to the network. The dynamic distribution of capacity between networks can be realized either in a centralized or in a distributed manner. If the division is performed in a distributed manner for example in such a way that each network independently allocates a band to itself, the algorithms used in the different networks must be compatible.

摘要： A method for controlling transmission power of a radio transmitter in a cellular communications system, such as in a CDMA-system, which includes determining a reference value (SIR.sub.m) indicating the quality of the signals received from the radiotransmitter, determining a reference value (P.sub.m, SIR.sub.pm) indicating the current traffic load in the radiocell, and commanding the radio transmitter to adjust transmission power. In order to improve speed and reliability during any traffic conditions the method includes comparing both the reference value (SIR.sub.m) for the quality of the received signals, and the reference value (P.sub.m, SIR.sub.pm) for the traffic load with predetermined target values (SIR.sub.t, P.sub.t, SIR.sub.pt), and practicing the commanding of the radio transmitter to adjust its transmission power depending on the result of the comparison.

摘要： The present invention relates to a connection establishment method and a radio system. When a base station (11) detects a preamble (20) from a subscriber terminal equipment (13), the power adjustment of a closed loop is started for controlling the transmission power of the subscriber terminal equipment (13). Signals (15) of the base station (11) and the subscriber terminal equipment (13) are synchronized and the subscriber terminal equipment (13) sends a randomly selected identifier. The identifier determines a transit channel to which the subscriber terminal equipment (13) suggests to move. The base station (11) may change the suggested transit channel and echo the identifier back to the subscriber terminal equipment (13), and the base station (11) and the subscriber terminal equipment (13) communicate on the transit channel from which they move to a traffic channel. The inventive method accelerates connection establishment.

摘要： When starting a radio transmitter, a transmission frequency is generated by a phase/frequency-locked loop which includes a phase/frequency comparator, a loop filter and a voltage-controlled oscillator. The start-up is performed by switching on an operating voltage to the voltage-controlled oscillator. To minimize the frequency error of the transmitter at start-up, measuring data about relationship between the control voltage of the oscillator and the output frequency of the oscillator at a specified calibration temperature are pre-stored in connection with the oscillator, and immediately before switching on the operating voltage, the control voltage needed for locking onto the selected output frequency at the prevailing temperature is estimated and the estimated control voltage is set as the control voltage of the oscillator.

摘要： The invention relates to a method for improving the reliability of a handover and call establishment in a cellular radio system which comprises at least one base station in each cell, and a group of subscriber terminal equipments which communicate with one or more base stations. The base stations measure the total interference level of signals they have received from the terminal equipments, and transmit a pilot signal with a known transmit power. The terminal equipments measure the power levels of pilot signals received from different base stations. In the system at least some transceivers comprise circuitry for estimating, by means of the pilot signals, the path loss between the terminal equipment and the base stations. To improve the reliability of the handover and call establishment, at least some transceivers in the system of the invention estimate the signal to noise ratio between the terminal equipment and the base station in the uplink transmission direction on the basis of the total interference measured at the base station, the path loss, and the terminal equipment transmit power.
