4.9.7.3.10 Best BST/AU
An SU that can communicate with more than one AU may become associated with
the first AU it "finds", not necessarily the best choice in terms of quality of
communication. Changes in Base Station deployment and subscriber density can
accumulate to create substantial changes in SU performance. The quest for load
sharing together with the desire to create best throughput conditions for the SU
created the need for the Best AU feature, to enable an SU to connect to the best
AU in its neighborhood.
When the Best BST/AU feature is enabled, the SU scans all AUs in a predefined
range, in all frequencies (according to the frequencies defined in the Frequency
Scanning menu as described in Section 4.9.7.3.11) and in all available antennas
(according to the local definition in the SU, as indicated by the Antenna Selection
parameter in the Show menu of the SU). Each of the AUs with which the SU can
communicate (perform initial phase of network entry) is given a quality mark
based on the quality of the signal at which it is received by the SU. At the end of
the scanning period, the SU reaches a Best AU decision according to the
information gathered. The AU with the highest quality mark is selected as the
Best AU, and the SU will immediately try to associate with it at the relevant
frequency.
The range used for scanning is defined by the Base Station ID parameters of the
SU. The initial range can be limited by defining a preferred range of AUs, and
selecting the best AU in the preferred range. If no AU is found in the preferred
range, the SU will scan the entire range.
The Best BST/AU Parameters menu includes the following options:
