Adaptive Configuration of Typical HSPA Rate Feature

With High Speed Packet Access (HSPA), mobile operators can provide services with diversified traffic rates. This is beneficial to mobile operators in many cases, such as in competing with fixed-line operators and in justifying service fees. The typical traffic rates configured at the Radio Network Controller (RNC), however, are fixed and separated, and may be inconsistent with the maximum bit rates (MBRs) configured at the core network (CN).

If an inconsistency occurs, the RNC selects a typical traffic rate closest to the MBR assigned by the CN. This rate, not the MBR, is then used for calculating the actual maximum traffic rate of the UE. As a result, the rate used by the UE is inconsistent with the MBR configured at the CN, and user experience may be affected.
