摘要
Disclosed is a call admission controlling device and method for providing QoS (quality of service) in the portable Internet. When a mobile terminal requests a guarantee of the corresponding QoS and a call admission, a packet access router calculates a bandwidth available for resource reservation according to mobility characteristics of a cell to which the mobile terminal belongs, and determines resource reserved states according to the mobility characteristics with adjacent cells based on the calculated bandwidth to thus control call admission in order to satisfy a handoff dropping probability of the corresponding cell and prevent disconnected calls when a handoff toward the adjacent cells occurs. As a result, the handoff dropping probability of cells is guaranteed, and the resources are utilized effectively.
