Patent ID: 7746806

Claim:
A method for determining the capacity that is needed on an lub link to fulfill Grade of Service (GoS) requirements in a Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN) for both Dedicated Channel (DCH) traffic and High-Speed Downlink Packet Access (HSDPA) traffic, wherein said lub link comprises a link between a Radio Network Controller (RNC) and a Node-B, said method comprising the steps of: determining the bandwidth demand of said HSDPA traffic (ElasticDim); calculating an average bandwidth of said DCH traffic on said lub interface (BW use.avg ); setting an initial capacity (Capacity) to the capacity need of said DCH traffic (Capacity DCH), wherein at least said initial capacity will be provided for said DCH traffic in the dimensioned system; and, increasing the value of Capacity until a quality requirement of said HSDPA traffic is fulfilled, the maximum value of Capacity reached being the capacity that is needed for DCH and HSDPA traffic for said lub interface.
