Generalization of quality class indices in a wireless network

摘要

A PCEF (400) for a cellular system, arranged (405, 410) to receive data packets from at least one other node via a certain Radio Access Technology, RAT, the PCEF (400) also being arranged to communicate with a PCRF via a PCC interface. The PCEF (400) is further arranged (425, 430) to set up Service Data flows, SDFs, which SDFs are defined for the PCEF (400) by the PCRF over the PCC interface and which comprise filters for received data packets. Said filters define a Quality Class Index, a QCI, for each received data packet, and the PCEF (400) is arranged (415, 420) to interpret QCIs for received data packets up to and including a predefined value in a first predefined manner for all RATs, and to interpret (415, 420) QCIs over said predefined value in a second predefined manner.

主权项

1. A network node including a Policy and Charging Enforcement Function, PCEF, for a cellular system, the network node configured to, via the PCEF:
receive data packets from at least another node in the cellular system via a certain Radio Access Technology, RAT; communicate with a Policy and Charging Rules Function, PCRF, via a Policy and Charging Control, PCC, interface; set up one or more Service Data flows, SDFs, which one or more SDFs are defined for the PCEF by the PCRF over the PCC interface and which comprise filters for the received data packets, said filters defining a Quality Class Index, a QCI, for each received data packet; for each received data packet, in response to determining that a corresponding QCI value is less than or equal to a predefined value, interpret the corresponding QCI in accordance with a first predefined manner for all RATs; and for each received data packet, in response to determining that a corresponding QCI value is greater than the predefined value, interpret the corresponding QCI in accordance with a second predefined manner.
