Abstract: A method for selecting radio access system in a multi access system handling packet data services where a terminal can communicate with at least two different types of access systems. According to the invention the method comprises the steps of:—determining (S23) packet characteristics of each packet to be transmitted;—selecting (S31) one of the available accesses for the transmission of each packet, the selection being based on the determined packet characteristic for this specific packet; and—transmitting (S37) the packet through the selected access.

Abstract: Users of a given service in a wireless communication system that includes a plurality of multi-service subsystems are allocated to one of the subsystems in accordance with a combined capacity region of the wireless communication system. The combined capacity region is determined based upon capacity regions of each of the plurality of multi-service subsystems. The capacity regions of the plurality of multi-service subsystems are determined using a relative decrease in users of a first service as a function of an increase in users of a second service.

Abstract: ABSTRACTA method in a system using a contention based multiple access protocol for controlling a transmission time a transmitting station may transmit data to a receiving station over a medium.According to the invention the method comprises the steps of:- selecting (S35) a transmission rate for the data to be transmitted to the receiving station;- controlling the expected waiting time per transmitted bit given to the transmitting station based on the selected transmission rate and stations transmitting data with a comparatively low transmission rate are given an increased expected waiting time per transmitted bit in relation to stations transmitting data with a higher transmission rate.(Fig. 3)

Abstract: The present invention relates to a method in a wireless communication system and in particular better usage of available radio resources in such systems by controlling the party effects using user based scheduling back-off. The scheduling back-off according to the invention is based on providing and controlling the number of channels/frequencies/codes/timeslots or fractions of channel use to a terminal depending on information regarding radio channel quality obtained from the system.

Abstract: The present invention pertains to the field of methods and apparatuses relating to radio communication; and in particular to the part of this field that concerns cellular radio communication. The present invention addresses mainly the problem of improving reliability and communication quality in a cellular radio communication system (1). According to the invention, it is determined whether one of an uplink (25) or a downlink (25) of a radio channel (23) is subject to a Rayleigh fading dip. If it is determined that one of the uplink (25) or the downlink (27) is subject to a Rayleigh fading dip, it is then determined whether it is necessary to execute a countermeasure in order to avoid the negative influences of Rayleigh fading on the channel (23). The invention is not limited to improving conditions on one channel but may be employed to any number of channels used for communications in the cellular radio communication system (1).

Abstract: Each base station (14) in a cellular telephone system includes a signal strength measurement device (30, 32) operable to tune to and make signal strength measurements on not only the frequencies allocated to other cells, but also on its own allocated frequencies. Measurements (104) are made by the device on those of its own frequencies having idle traffic channels to obtain an indication of injected uplink interference. An interference penalty is then assessed (114) against the measured uplink interference for those frequencies having more than a threshold number (110) of idle traffic channels. The adjusted measurements for the frequencies allocated to the cell are then sorted (118) in relative order of idle traffic channel (adjusted) measured uplink interference from a least (adjusted) interfered frequency to a most (adjusted) interfered frequency. An idle traffic channel is then selected for assignment (120) at either call set-up or hand-off from the least (adjusted) interfered frequency.
