Abstract

A system, an apparatus, a method and a computer program product for transmission of data packets using wireless data priority services in wireless communications system. A priority level for a user equipment is determined. Based on the determined priority level for the user equipment, an admission control procedure to reserve transmission capacity for the user equipment is executed. Based on the determined priority level for the user equipment and the reserved transmission capacity, at least one data packet for transmission to and/or from the user equipment is scheduled. Based on the scheduling, the data packet is transmitted.
