Method and arrangement for optimizing the re-establishment of connections in a cellular radio system supporting real time and non-real time communications

Claimed is a method and device is used to determine of transmission time interval term full time for reconstruction radio carrier of licence. The first determining that term time (206,207) is reflected time interval, is used for providing the first category service (analyses service real-time) consumption the reconstruction radio carrier of licence during the time interval. Additionally, further - comprising an second term full time (208,209) is reflected time interval, is used for providing the second category service (analyses non-real-time service) consumption the reconstruction radio carrier of licence during the time interval.
