context: Figure 6.1.1.2-1 Example of Solution 1 Figure 6.1.1.2-1 shows an exemplary illustration of how solution 1 works. - UE receives ANDSF policies from the ANDSF server (ANDSF client is implemented in this case), or has pre-provisioned ANDSF policies. - The ANDSF policies include RAN/WLAN parameters to be added to WLANSP node (for WLAN AP selection) and/or ISRP node (for traffic routing) in TS 24.312 [4] of Rel-12 by receiving inputs from this RAN2 SI/WI. Details are FFS. Some RAN/WLAN parameters are listed below for illustration: - RSRP/RSRQ threshold: in unit of dBm/dB - Offload Preference threshold: would be the form of, for instance, - One bit (e.g. true/false) - Two bits (e.g. 0, 1, 2, 3 to indicate the level of offload preference threshold) - Offload percentage value (similar to ac-BarringFactor to prevent massive toggling) - Figure 6.1.1.2-2 shows an example of enhanced ANDSF MO based on the above descriptions. In this example, the above example parameter(s) are added as e.g. the
description: The Bit Error Ratio (BER) is a measure of the number of bit errors that occur in a transmission system. It is used to evaluate the performance and reliability of data transmission over a communication link. In this context, BER refers specifically to the error rate of bits transmitted over a transport channel or physical channel, which is utilized by the DRNS for Quality of Experience (QE) evaluation.
explanation: BER is classified as a Measurement because it represents a quantifiable metric used in assessing the performance and reliability of data transmission. The context explicitly states its use in evaluating error rates over transport channels, further solidifying its categorization under Measurement.
