Reserve Bandwidth for Users with Different Priorities to Obtain Higher QoS

[adewijaya]

In Huawei system, For PS services, concerning the QoS, there will be four kinds, conversational, streaming, interactive and background. Generally speaking,
service priorities are decreased as the above sequence. The conversational service has the highest priority and background has the lowest.
It is the same situation to the terminal user feelings. For services with higher priorities, including conversational and steaming, to ensure
their QoS, RNC will use the subscribed GBR as their final GBR. Because more resources will be occupied by such kind of services,
operators only subscribe a few users with these kinds of services. Most users are using interactive or background services. But how to
reserve bandwidth for INT and BE users? From the signal message flow, for every subscriber, there is a parameter named ARP.
The range of ARP is from 1 to 14, normally. It is used to identify the user priority. This parameter will be transfer to RNC by SGSN in RAB
Assignment Request message. When receiving this message, RNC will try to find out the corresponding priority level, like Gold, Silver or
Copper, according to its configuration. And for Gold, Silver and Copper users, different GBR have been configured in the RNC system.
In this case, the services of these terminal users have been ensured.

How to do this :

1.Make a plan about ARP, generally for RNC setting, 1 to 5 are Gold, 6 to 10 are Silver and 11 to 15 are copper.
2. Set the ARP parameter as 1 on HLR.
3. Use command SET USERPRIORITY, to set ARP1 as Gold user.
4. Use command SET USERGBR, to set GBR for Gold user.
