uplink opportunities for data transmissions, as well as RANDOM ACCESS procedures. During busy hours, when there are many users already connected to the cell and many more trying to connect to the cell by means of RANDOM ACCESS procedures, it becomes very important for the operator to be able to select the right base station setting for RANDOM ACCESS opportunities in order to balance the distribution of the uplink subframes between RANDOM ACCESS opportunities and user data transfer opportunity. Reduce interference during a RANDOM ACCESS procedure. In a homogeneous network, where there are multiple cells deployed, there is a huge probability of uplink interference that can result in performance drops for the entire network. Care should be taken to ensure that the neighboring cells that are operating at the same frequency avoid using the same root sequence number. Also it is very important to ensure that the PRACH opportunities between the two neighboring cells are different and do not have RACH opportunities at the same time and frequency. Reduce call setup and handover delays. This is extremely important in a deployment where there are users who are traveling at a higher speed. The RACH optimization feature aims at automatically fine tuning the RACH parameters to enhance system performance. One of the targets listed in Table 2-1 should be used. Some of the performance targets that are configured by the operator as per the guidelines from 3GPP specs are outlined in the table. Table 2-1. Performance Targets from 3GPP Specifications Target Name Definition Legal Values Access probability (AP) The probability that the UE has for accessing the network Cumulative Distribution Function after a certain number of random access attempts. (CDF) of access attempts Access delay The probability of the delay that an UE can experience CDF of delays probability (ADP) while accessing the RACH.
