Abstract: The invention relates to a method for the allocation and release of channels in a communication system. A first session is established associated with the first mobile node via a radio node and a call control node to a conversation state. The establishment of a second session associated with a second mobile node is started in the same cell. The lack of available channels in the cell is determined in association with the second session. The first session is selected for dropping based on information on the session within the cell. The first session is released in response to the selection. Thereupon, the channel thus made available is allocated for the second session in the radio node.

Abstract: The present invention relates to a method and apparatus for controlling a connection transfer in a cellular network having at least two systems, such as a GSM system and a WCDMA system. Based on a load determination, a service-based inter-system or inter-frequency handover of the connection to another system or to another carrier of the same system is initiated if the determined is below a threshold and service priorities are indicating it. If it exceeds the threshold, an additional load-based inter-system or inter-frequency handover can be initiated. If the load of the target cell is not known, a load estimation based on a learning process can be used to derive a probability of success of an interfrequency or inter-system handover, which may be used for deciding on the initiation of the inter-system handover. The learning process may be performed by evaluating preceding interfrequency or inter-system handovers to the target cell or preceding interfrequency or inter-system handovers from the target cell.

Abstract: The present invention relates to a resource allocation method, network controller device and a switching control device allocating resources to a subscriber of a communication network, wherein at least one allowed codec type is selected for the subscriber based on a relative priority information received from the communication network, e.g., from the switching control device (40). The selected at least one allowed codec type is signaled towards a terminal device (10) of the subscriber. Thereby, priority-based user differentiation can be introduced to provide different quality of service based on the allocated relative priority. This allows maintaining high quality services even in high load or low signal strength environments.

Abstract: An inter-frequency handover of a UE connection is performed in which the frequency of the uplink connection from the UE to a base station remains the same and the frequency of the downlink connection from the base station to the UE changes from a first downlink frequency to a second downlink frequency. A request for the handover is transmitted from the base station. The request containing information indicating the second downlink frequency and information indicating that the uplink frequency remains the same. In response to the request, the physical layer of the uplink connection is maintained while changing the downlink frequency from the first downlink frequency to the second downlink frequency.
