Claim:
1. A method for scheduling downlink in a radio access network based on a Quality of Service (QoS), the method comprising: performing a packet scheduling for a plurality of user equipments (UEs) based on information regarding QoS classes, the information regarding the QoS classes being included in QoS class identifiers received from an Evolved Packet Core (EPC) providing communication services to the UEs, wherein the QoS class identifiers comprise at least two of a resource type, including Guaranteed Bit Rate (GBR) and Non-GBR bearer, a priority, a Packet Delay Budget, and a Packet Error Loss Rate, and wherein the packet scheduling maximizes a number of the UEs fulfilling QoS parameters in the radio access network, by performing steps comprising: defining a quality performance indicator Q defining a metric Q including a factor in a priority of a UE mapped onto a QoS class supporting a delay-dependent traffic, the factor comprising and the factor being multiplied by wherein the priority of the UE is defined by a product of the above two factors, and where: offset stands for a minimum priority, priorityAtTarget is a priority achieved considering the offset when the Q W TQ a is a constant, R r modifying the priority of the UE by multiplying the priority by a factor F combining scheduling strategies for the number of UEs of the QoS classes supporting the delay-dependent traffic and an elastic traffic by fulfilling: where: P i QCIm is a modified priority, and u(k) represents a resource block k that should be assigned to a bearer u.
