Abstract: A system, method and computer program for dynamic frequency allocation for packet switched services in which radio channels used for packet switched services may be dynamically allocated to meet quality of service (QoS) requirements utilizing a dynamic frequency and channel allocation system. The achievable throughput is estimated in the available channels. Further, the user or application is able to specify the level of service desired and the system, method and computer program will select a channel assignment to meet the desired level of service. When the channels to be assigned have been selected, the system, method and computer program will evaluate if the new channel assignment will cause excessive interference to any other ongoing connection. In such case the ongoing connection will be re-assigned to another suitable radio channel.

Abstract: A communication system covering an area, including a plurality of first units. Each of the first units being configured to control the allocation of channels in a part of the area. At least one of the first units being configured to send information relating to channel allocation in the part of the area associated with the at least one first unit to at least one other of the first units. The at least one other of the first means units being configured to take into account the received information when controlling the allocation of channels in the part of the area associated with the at least one other first units.

Abstract: A method of channel allocation in a cellular communication network wherein a radio channel is to be selected for establishment of a connection in an environment with potentially interfering signals, the method comprising: establishing a radio channel candidate; processing the radio channel candidate with potentially interfering signals and calculating a carrier to interference ratio (CIR) for the selected carrier frequency of the radio channel candidate and the potentially interfering signals; calculating a dominant interference ratio (DIR) being the ratio of the strongest potentially interfering signal with respect to the other potentially interfering signals; and using criteria based on at least one of the dominant interference ratio and the carrier to interference ratio in a selection process for selecting a channel for the connection to be established.

Abstract: A data transmission method in a telecommunication system utilizing frequency hopping and the system having a limit for allowable interference. The method includes performing at least two frequency hopping layers, each layer comprising one or more frequency hopping areas, the frequency hopping layers having frequency hopping parameters divergent from each other, setting the frequency hopping layers one on the other in such a way that the overlapping of the border zones of the frequency hopping areas is minimized, estimating interference in the system or in a predetermined part of the system, and if the interference is too high, transferring one or more users to another frequency hopping layer.
