CN Bearer Service Backbone Bearer Service

Some important QoS zTraffic Class：conversational, streaming,interactive,and background. zMaximum Bit Rate（MBR）：The Maximum bitrate is the upper limit a user or application can accept or provide. zGuaranteed Bit Rate (GBR)：Describes the bitrate the UMTS bearer service shall guarantee to the user or application. zTraffic Handling Priority：Within the interactive class, there is a definite need to differentiate between bearer qualities. This is handled by using the traffic handling priority attribute, to allow UMTS to schedule traffic accordingly. zAllocation/Retention Priority：Priority is used for differentiating between bearers when performing allocation and retention of a bearer.

Basic Priority (BP) Mapping z BP is mapped from the Traffic Class, ARP Seg, THP Seg of I services. It is divided into 16 levels (0 - 15, with the 15 the highest level, 0 the lowest) z When the RNC receives the ARP and THP assigned by the core network, it maps the BP based on the Traffic Class, ARP, and THP. z Because the value range (15) of The ARP and THP 、 the classes of Traffic Class is far beyond the value range (15) of BP, the values of the ARP and THP are segmented. z BP is used for Admission Control and HSPA Scheduling Abbreviated name Parameter name

Scheduling Priority Mapping z SP (SchPrio) is mapped from the BasicPrio and BearerType. It can be divided into 16 levels (0 -15, with the 15 the highest level, 0 the lowest). z Compared with BP, the SP takes one more factor – bearer type - into consideration to differentiate the priorities of different bearer types. z The SP is used to schedule the call queue and to select the subscriber to be released in forced release.

QoS Differentiation of Admission Control zDifferent admission thresholds can be set in admission control based on BP and different transmission channels. zOperator can determine the degree of difficulty to be admitted for users/services with different ARPs by setting different admission thresholds for different priorities. For example, when the load is heavy, Operator can admit users with higher priority and refuse those with lower priorities, so as to avoid impact on service quality of higher-priority users caused by lower-priority user admission.

QoS Differentiation of Congestion Control In the event of system congestion, resource preemption can be triggered to reflect superiority of subscribers with higher priorities and improve call successful ratio. Its main policies consist of two aspects as follows: zForced release: The services capable of preemption with higher priorities are allowed to release forcibly those services with lower priorities. That is, the subscribers with higher priorities can implement fast access by preempting the resources of those subscribers who are of lower priorities and subjected to forced release. This is to reflect differentiation of services between subscribers. zDowngrade: This policy is used to improve call successful ratio by decreasing the data bit rate of online subscribers.

13

QoS Differentiation of Congestion Control -Forced release Forced release: selection of users to be released forcibly and priority judgment between users originated forced release and users to be released forcibly are based on the SP. There are three users in the network: UE1, UE2, and UE3. Now UE4 wants to be admitted to the network. However, the network is now congested.

QoS Differentiation of Congestion Control - Rate Decrease Rate Decrease : selection of users whose rate is to be decreased in the rate decrease is based on comparison between APs. And AP reflects ARP. Therefore, ARP differentiation is reflected in the preceding strategy. There are three online users: UE1, UE2, and UE3. Suppose that a new user UE4 requires access to the network, which is now congested due to insufficient downlink power resources in the cell.

Summary of Scenarios Applied for BP\SP\AP Priority

Function

Scenarios

Basic Priority(BP)

Admission Control HSDPA Packet Scheduling HSUPA Packet Scheduling

(1) When RAB is admitted, RNC obtains admission threshold based on BP. (2) For HSDPA, when resources for HSDPA are shared by multiple users, RAN (Node B) will allocate the code and power resources to different HSDPA mobiles according to SPI which is equal to BP. (3) For HSUPA, when resources for HSUPA are shared by multiple users, RAN (Node B) will allocate the grant to different HSUPA mobiles according to SPI which is equal to BP.

SP of RNC(SP)

Congestion Control

(1) When forced release is performed because of resource congestion, RNC will select users to perform forced release based on SP. (2) When queueing and service admission again are performed because of resource congestion, RNC will select users to perform admission based on SP.

Application Priority(AP)

Congestion Control OverLoad Control

When downgrading is performed because of resource congestion, RNC will select users to perform downgrading based on AP. When overload happens, RNC will select users to decrease load based on AP. 18
