Abstract
A base station (105) comprises a notification processor (117) to transmit notification information of calls of a call service to remote terminals. The call service can be a GSM Voice Group Call Service (VGCS). The notification processor (117) comprises a BCCH processor (303) which notifies active calls for the call service to remote terminals in a first set of allocated radio blocks (201, 203) on a broadcast channel. A VGCS processor (307) determines that a new call is initialised, and in response the notification processor (117) replaces a notification for an existing call with a notification for the new call in at least one radio block of the first set of allocated radio blocks (201, 203).
