Abstract:
1. A method of operating a telecommunications network comprising: configuring at least one set of radio transmission resources of a cell as a non-hopping set of radio transmission resources; configuring other sets of radio transmission resources of the cell as hopping sets of radio transmission resources; scheduling calls comprising voice over internet protocol packet flows on the non-hopping set of radio transmission resources in accordance with capacity of the non-hopping set of radio transmission resources; determining whether the non-hopping set of radio transmission resources lacks capacity for a further call with a mobile station by determining whether any non-hopping resource is currently available for allocation to the new call; and when the non-hopping set of radio transmission resources lacks capacity for the further call with a mobile station, requesting that the further call be changed from a voice over internet protocol packet flow to a circuit switched connection hopping resource of the cell.
