Abstract
A telecommunications network comprises a base station node (28) which provides plural sets of radio transmission resources (52) for communicating with mobile stations (30) in a cell (40). At least one set (521) of radio transmission resources of the cell is a non-hopping set of radio transmission resources including a resource which may carry the BCCH, and other sets (521-52n) of radio transmission resources of the cell are hopping sets of radio transmission resources. A base station controller (26) node schedules calls comprising voice over internet protocol packet flows on the non-hopping sets of radio transmission resources in accordance with capacity of the non-hopping set of radio transmission resources. When the non-hopping set of radio transmission resources lacks capacity for a further call with a mobile station, the base station controller (26) node requests that the call be changed from a voice over internet protocol packet flow to a circuit switched connection.
