Abstract: A method and an apparatus for allocating channels to multislot connections in a mobile telecommunication network are disclosed. The method includes the steps of sorting all available channels into Multislot Resource Groups (RGs), then selecting one of the RGs fulfilling the following requirements: at least the requested number of idle channels are identified, fulfilling the requirements of the mobile class of the mobile terminal concerned, as few idle channels as possible above the requested number of channels, belonging to the least adaptable TCH capabilities group, following the selected strategy for the non-hopping TCHs on the BCCH frequency, having the lowest interference, and if frequency hopping is used, hopping over as many frequencies as possible.
