name: BSC
full_form: Base Station Controller
context: does not wait for a too long time before transmission. Besides, [9] has not specified any value for CU_Timer. Due to the CU_Timer_ effects, the number of selected VCs to carry AAL2 user data also affects with a direct dependence the AAL2 performance. By distributing AAL2 traffic over several VCs, each ATM connection load decreases (and consequently, probability of Timer_CU expiration increases). Consequently, the PTD and PDV tend to increase. Moreover, PTD and PDV are impacted by ATM cell queueing at the network switches: The data-rate of the physical link and the physical protocol (IMA upon PDH, SDH, â¦), Included in the QoS, the CTD and the CDV of the corresponding ATM connection also affect AAL2 performance. The ATM link load obviously impacts AAL2 performance by increasing the delay component.
description: The Base Station Controller (BSC) manages radio resources and controls multiple base transceiver stations in a GERAN Iu-mode network. It handles RAB Assignment procedure requests from the CS domain and provides GERAN-specific information for successful operation.
explanation: The BSC is classified as a Network Function because it performs crucial control and management functions within the GERAN Iu-mode network, as described in the text. Its role in the RAB Assignment procedure and provision of GERAN-specific information highlights its functional importance.
