Abstract
Abstract To achieve an increased access to subscribers in a mobile cellular network with a plurality of service areas each covered by a related switching center, in each such switching center ( 10 ) there is provided an interface means ( 12 ) to establish a plurality of communication channels between the switching center ( 10 ) and a mobile station (MS) roaming in the service area of switching center ( 10 ). Further, the communication channel assignment at the interface ( 12 ) is changed through an assignment means ( 14 ) processing assignment requests submitted thereto. Further, reservation requests are used to indicate to the switching center ( 10 ) that a specific subscriber wants to reserve communication channel capacity for a specific cell in a mobile cellular network during a specific time period according to a specific bandwidth. If this bandwidth is available at the specified cell during the specified period of time, it will be reserved for the requesting subscriber which then may easily initiate calls-services or receive calls-services by the reserved communication channel capacity at the start time (t s ) of the prespecified period of time.
