31、Based on SPI weight,Benefits,This feature is mainly applicable to HSPA channels.It provides userswith differentiated services according to user priority or service type,This feature supports differentiated tariff policies,for example,high-tariff users are provided with better services,Description,If
32、 this feature is not enabled,the resource scheduling algorithmsmainly ensure the fairness between BE services.That is,the resourcescheduling algorithms fairly allocate resources between users basedon the guaranteed bit rate(GBR)and maximum bit rate(MBR)required,After this feature is enabled,SPI weig
33、hts can be set for user priorities(gold,silver,and copper).Resources are allocated according to theset SPI weights.The quality of services with high SPI weight ispreferentially ensured.For example,if Uu interface resources areinsufficient,higher data rate or shorter transmission delay is achievedpre
34、ferentially for services with high SPI weight,25,Feature Introduction WRFD-010505 Queuing&Pre-emption,Benefits,This feature provides a method to differentiate users via their priority.High priority users can obtain system resources with high priority incase of resource limitation,Description,Queuing
35、 and Pre-emption are two functions related to access controland are methods to differentiate services.It enables operators toprovide different services by setting different priorities,which will affectthe user call setup success rate during the call setup procedureIf there are not enough resources a
36、nd a new call is not admitted toaccess to the network,high priority user will have more chances toaccess to the network than low priority users by queuing or pre-empting other low priority users,26,Feature Introduction WRFD-050424,Traffic Priority Mapping onto Transmission Resources,Benefits,This fe
37、ature implements the mapping from traffic priorities to,transmission resources and provides flexible configuration means fordifferentiated services and for guarantee of QoS,Description,This feature dynamically maps the services onto the transport bearers,according to the TC(Traffic Class),ARP(Alloca
38、tion/Retention Priority),and THP(Traffic Handling Priority for interactive service)of the user.The operator can flexibly configure the mapping of service types ontotransmission resources.According to different combinations ofTC+ARP+THP,the operator can choose the transmission resourceswith different
39、 QoS requirements to fulfill differentiated services(eg:Gold,Silver,Bronze),while guaranteeing the QoS,27,Feature Introduction WRFD-021103 Access ClassRestriction,Benefits,This feature reduces signaling overload(call attempts)to increasenetwork accessibility.Therefore,CN load is also reduced,Descrip
40、tion,The PRACH resources(i.e.access slots and preamble signatures forFDD)and timeslot may be divided between different Access ServiceClasses in order to provide different priorities of RACH usage,Access Service Classes shall be numbered in the range 0 i NumASC 7.The ASC 0 has the highest priority,an
41、d the ASC 7 has,the lowest priority.The ASC 0 shall be used in case of EmergencyCall or for reasons with equivalent priority,When the cell or system is overloaded,this feature can restrict useraccess based on the service class allowed by System informationblock(SIB),thus controlling potential load r
42、equirements of the system,28,Feature Introduction WRFD-010637 HSUPA Iub FlowControl in Case of Iub Congestion,Benefits,This feature can improve the transport resource usage efficiencygreatly and reduce the throughput fluctuation in the case of the Iubcongestion,Description,This feature enables the m
43、onitoring of Iub transmission resources todynamically adjust the uplink Uu throughput,thus greatly improvingthe resource utilization,The UL Uu throughput is controlled by the scheduler according to theUL load resource and the Iub bandwidth resource simultaneously.Theschedule algorithm estimates the
44、influence on the load resource andthe Iub resource of the change of the serving grant(SG)and decideswhether to assign the absolute grant(AG)or relative grant(RG)toUEs,29,Huawei HSPA Differentiated Service,HSPA Differentiated SolutionDifferent subscriber will have different perception.VIP users perce
