Abstract
A telecommunications system (18) comprises a control node (24) and a base station node (22). The control node (24) maintains a first list (42) of idle radio channels which is consulted in order to obtain channels for a first type of telecommunications service. A second list (56) of idle radio channels is maintained for a specialized telecommunications service, the idle radio channels of the second list being radio channels which are unallocated with respect to the specialized telecommunications service but yet activated (e.g., having an established transmission path and synchronization). The second list of idle radio channels is initially consulted in order to obtain channels for the specialized telecommunications service. If no channels are available for the specialized telecommunications service on the second list, idle channels from the first list are adapted and utilized for the specialized telecommunications service. The specialized telecommunications service preferably involves packet data transfer (e.g., GPRS). As one aspect of the invention, any potential capacity problem is addressed by providing timers for channels on the second list. There is one timer corresponding to e…
