Abstract:
A method for dynamic division of radio capacity between packet radio service and circuit switched service in a TDMA system in which two-way traffic between base station systems and mobile stations takes place in time slots on predetermined channels, characterized in that:in a basic mode a base station system reserves a first predetermined number of time slots for packet radio service and a second predetermined number of time slots for circuit-switched service on said predetermined channels, and thaton the basis of a predetermined criterion, said base station system allocates at least one additional time slot to one of the packet radio service and circuit switched service, said predetermined criterion being selected from the group consisting of:a new packet radio connection is set up;an existing packet radio connection is terminated;a new packet radio session is set up:an existing packet radio session is terminated;a handover concerning a certain mobile station is performed; anda certain threshold value is reached in a traffic measurement performed at said base station system.
