Allocation of channels for packet data services
First Claim
1. A telecommunications system comprising a control node and a base station node, wherein the control node maintains a first list of idle radio channels which are available for a first type of telecommunications service, wherein the improvement comprises a second list of idle radio channels which are available for a specialized telecommunications service, the idle radio channels of the second list being radio channels which are unreserved with respect to the specialized telecommunications services but yet activated by having an established transmission path and synchronization.

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).

- 26. A telecommunications system comprising a control node and a base station node, wherein the control node maintains a first list of idle radio channels which are available for a first type of telecommunications service, wherein the improvement comprises a second list of idle radio channels which are available for packet data transfer, the second list being managed whereby, after a channel from the second list is reserved by a mobile station and then de-reserved, the channel from the second list remains activated by retaining an established transmission path and synchronization.

33. A method of operating a telecommunications system comprising a control node and a base station node, the method comprising:
-
maintaining a first list of idle radio channels which are available for a first type of telecommunications service; maintaining a second list of idle radio channels which are available for a packet data transfer service, the idle radio channels of the second list being radio channels which are unreserved with respect to the packet data transfer service but yet having an established transmission path and synchronization; responding to a request for a radio channel for use by the packet data transfer service by choosing a radio channel from the second list and reserving the chosen radio channel; upon de-reservation of the chosen radio channel, keeping the chosen radio channel on the second list and thereby remaining activated by retaining the established transmission path and the synchronization. - View Dependent Claims (34, 35, 36, 37)
