The resource pool canimprove the hardware reliability of (ode%s. There is no impactwhen $A( sharing isintroduced.Softare "icense !ased Resource PoolThe baseband resource is license managed. The resources ofone e#ui$alent %&.& 'bit(s A)R $oice*including +., 'bit(s -CCH* consumed in baseband processing is defined as one channel element license." / -" Channel Element Concept:There are two *inds of Channel &lements C&s! one is uplin* C& for uplin* service and the other is downlin* C& fordownlin* service. The C& calculation is based onthe "# regardless of the typeof radio lin*, sector, and fre)uency.Therefore uplin* C& and downlin* C& form aresource pool based onlicenses.The number of C& licensesconfigured must be within the basebandhardware capacity. If the number of consumedC&s reaches the configured number of C& licenses, an alarm is generated, which indicates the need to epandoperator licenses.The resource pool basedon licenses can fleibly evolve tomeet the re)uirements of $A( sharing.5hen $A( sharing is introduced, C& licenses canbe fleibly partitioned into several C& license groups. Thesummed groups must be within the baseband hardware capacity. &ach group is managed by one license. Thehardware capacity can be shared by all the groups.The baseband processing resources usedby various traffic types are always normali6ed to the 02.2 *bit7s voicechannels. "ince the number of the voice channel is epressed inChannel ElementC&!, capacity of the trafficchannels supported by the (ode% is also epressed in C&s

Consumption of Credit on DCHConsumption of Credit on HSUPA (E-DPDCH)The reason why + credit consumption 8 2 9 + C& consumption for the same data rates andservices is that 0.:C&s are consumed by + ;" 12 *bps. ?.The amount of credit consumedby the &-D;CC' e)uals one.

"ince '"-D"C'resources are controlled by (ode%, the $(C as*s forprovision of necessary transport resources using the #;'"-D"C' capacity re)uest message. In the capacity allocation message (ode% signals what was granted. $C ;D+stransmitted for this specific call are prioriti6ed using a priority indicator that has a value in the range from 3 to0: 0:indicates highest priority!. The credit information element represents the number of $C ;D+s thatthe $(C isallowed to transmit within a certain time interval. The interval is amultiple of the TTI used inthe '"-D"C', a typicalTTI value is 2 ms.5hen performance-related data from (ode % is available together with thedata captured by thelub porbes, it can be proved that there is alinear correlation between CBI sent by +& on radio interface to theserving '"-D"C' cell and the credits sent bythe cells (ode % tothe "$(C. 'ence, evaluation of credits allows toestimate values of CBI although CBI isnot transmitted via lub interface. After all data hasbeen transmitted by the$(C, (ode % will send anther capacity allocation message that starts the net se)uenceof D data transfer andthis procedure will continue in thesame way as longas '"-D"C' is used by a+&.
