Measurement of PS RAB assignment failure per cell(RAB.EstFailPs.Cell)

Overview

The CN in PS domain initiates the radio access bearer setup procedure by sending a RAB ASSIGNMENT REQUEST message to the RNC.After receiving the RAB ASSIGNMENT REQUEST message, the RNC selects an appropriate cell, allocates resources, and performs admission control based on the information in the message (such as service type, QoS, and priority), the traffic load of the system, and the networking strategy (such as DRD). Therequirements of high-priority users are met preferentially(That is, when the resources are insufficient and the UEs with low-priority cannot set up the RAB, the RNC sends to the CN a RAB ASSGNMENT RESPONSE message if the queuing algorithm is enabled, indicating that the RAB is in the queue to wait forresources). If the admission of the RAB succeeds, the RNC starts the Iu transport connection setup procedure, the Iub radio bearer setup procedure, and the Uu radio bearer setup procedure. At last, the RNC sends to the CN a RAB ASSNMENT RESPONSE, indicating whether the RAB setup is successful. If DRD is enabled during the RAB setup, the RAB setup measurement is performed on the DRD target cell. Otherwise, the RAB setup measurement is performed on the DRD source cell.The RAB setup procedure is as follows.
