RNC Pilot PO Optimization

This document provides several measures to help relieve radio frequency (RF) congestion during special events like large gatherings that last a day or two. These include reducing the quantity and time between RRC setup request retransmissions; increasing timers for location area updates and guaranteed bit rate adjustments; adjusting timers that control RRC connection setup retransmissions; lowering thresholds for uplink access control; enabling downlink power control; and reducing rise-to-waste power through E-DPDCH and HS-DPCCH configuration changes, and RACH parameter optimization. The measures aim to temporarily limit network signaling load through configuration changes tailored to short-term congestion scenarios.

The document discusses HSPA MAC-centric technologies including HSDPA and HSUPA. It provides an overview of 3GPP UMTS evolution from Release 5 to Release 8, which introduced HSDPA and HSUPA to improve peak data rates and reduce latency. It describes key aspects of HSPA such as the location of MAC-hs at the Node B to enable fast scheduling and HARQ, as well as transport and physical channels used in HSDPA and HSUPA like HS-DSCH, E-DCH, HS-SCCH, and HS-DPCCH. It also covers flow control between the Node B and RNC and enhancements introduced in Release 6.

1. The average downlink throughput of R99 PS UL64k/DL64k service should be between 48-56 kbps. 2. The average downlink throughput of R99 PS UL64k/DL128k service needs to meet requirements. 3. Tests are conducted in areas with good radio conditions and low traffic. FTP servers are placed in the core network, and downloading uses 5 threads. Non-RAN problems and UE-related throughput declines are excluded.

This document provides a guide for optimizing W-handover and call drop problems in WCDMA networks. It discusses key performance indexes for handover and call drops. It then outlines optimization flows for DT/CQT analysis and traffic statistics analysis. The document details various SHO, HHO, and inter-RAT handover problems and provides case studies. It also includes definitions of terms and descriptions of signaling flows. The overall aim is to help network operators identify and resolve handover and call drop issues.

The document discusses monitoring resources in a Huawei WCDMA network to avoid congestion and blockages. It describes monitoring resources at the NodeB and cell levels like CE cards, licenses, OVSF codes, power levels, and Iub bandwidth. Counters are presented to monitor traffic, KPIs, resource usage, and rejections due to congestion. The resource consumption of different services is also analyzed to understand network characteristics and identify if resources are sufficient for desired services.

This second webinar discusses LTE Air Interface, the link between a mobile device and the network, and a fundamental driver of the quality of the network.

Admission control guarantees quality of service by controlling the number of users based on interference, capacity, load, and coverage. It selectively denies access requests to limit load. Congestion control resolves overload by delaying packets, removing calls, or moving users between channels. Power control aims to minimize transmit power while maintaining quality by adjusting power levels through inner-loop, outer-loop, and open-loop control. Soft/softer handover combines signals from multiple base stations or sectors to support user mobility and power control.

Dual Carrier HSPA and Carrier Aggregation with a small comparison of the different mobile technologies architecture GSM, UMTS, and LTE.

This document provides an overview of HSDPA (High Speed Downlink Packet Access), which was introduced in 3GPP Release 5 to improve downlink packet data performance in WCDMA networks. Key aspects of HSDPA discussed include fast link adaptation, hybrid ARQ with soft combining, channel-dependent scheduling, higher order modulation, connection handling and mobility support, and capacity management functions. HSDPA utilizes a new high-speed downlink shared channel (HS-DSCH) to deliver packet data to user equipment at higher speeds than previous WCDMA networks.
