UMTS/3G RAN Capacity Management Guideline Part-02 (Sectorization))Md Mustafizur Rahman
UMTS RAN capacity management is one of the Key activities to maintain the good QoS & stability of the 3G system. A relatively high load can affect the accessibility, coverage and QoS of established services. The capacity, coverage and QoS of the WCDMA system are mutually affected. Hence, for a stable & good quality 3G network, UMTS capacity need to be monitored, expanded & manage regularly.
In the first part of document (Part-1) UMTS soft capacity management along with the correlation between capacity vs accessibility, UMTS expansion threshold, counters & effective mechanism of UMTS Soft capacity management have been depicted. This part of the Document is focused on UMTS Hard Expansion Methodology. 3G Capacity management by Sectorization has been explained thoroughly.
After completing this, you will be able to gain knowledge on 3G Expansion Parameters, 3G Expansion Threshold, Capacity Gain, Cost vs Capacity Gain by Sectorization. Moreover, you will be familiar with Planning, Optimization & Post Performance activities of Sectorization.

The GSM network is comprised of the following components:
Network Elements
The GSM network incorporates a number of network elements to support mobile equipment. They are listed and described in the GSM network elements section of this chapter.
GSM subsystems
In addition, the network includes subsystems that are not formally recognized as network elements but are necessary for network operation. These are described in the GSM subsystems (non-network elements) section of this chapter.
Standardized Interfaces
GSM specifies standards for interfaces between network elements, which ensure the connectivity of GSM equipment from different manufacturers. These are listed in the Standardized interfaces section of this chapter.
Network Protocols
For most of the network communications on these interfaces, internationally recognized communications protocols have been used
These are identified in the Network protocols section of this chapter.
GSM Frequencies
The frequency allocations for GSM 900, Extended GSM and Digital Communications Systems are identified in the GSM frequencies section of this chapter.
GSM networks are digital and can cater for high system capacities. They are consistent with the world wide digitization of the telephone network, and are an extension of the Integrated Services Digital Network (ISDN), using a digital radio interface between the cellular network and the mobile subscriber equipment
The GSM system provides a greater subscriber capacity than analogue systems. GSM allows 25 kHz. Per user, that is, eight conversations per 200kHz. Channel pair (a pair comprising one transmit channel and one receive channel). Digital channel coding and the modulation used makes the signal resistant to interference from the cells where the same frequencies are re-used (co-channel interference); a Carrier to Interference Ratio (C/I) level of 9 dB is achieved, as opposed to the 18 dB typical with analogue cellular. This allows increased geographic reuse by permitting a reduction in the number of cells in the reuse pattern. Since this number is directly controlled by the amount of interference, the radio transmission design can deliver acceptable performance.

Enhancing Network Visibility Based On Open Converged Network ApplianceOpen Networking Summit
Dr. Dongheon Lee' and Dr. Junho Suh's presentation from the 2017 Open Networking Summit.
As the mobile traffic carried by cellular networks has been growing rapidly and the networks gets bigger and more complex, network operators have been forced to search for solutions to substantially enhance network visibility. This talk introduces SKT integrated Network Analyzer (TiNA) and Converged Appliance Platform (T-CAP) which help us improving the efficiency of network operation, troubleshooting, and analyzing traffic. TiNA is composed of virtual network packet broker, flow analyzer, high speed packet dump system, connection performance analyzer, and 3D-based network management system. T-CAP is an open architecture of a server-switch type hardware. We will review how to implement those TiNA functions based on open source (e.g., DPDK, Spark Streaming) and T-CAP. Finally, we will also discuss about the use-cases of TiNA and T-CAP for the private cloud & telco network infrastructure.
Performance Evaluation of GTP-U and SRv6 Stateless TranslationChunghan Lee
The GPRS Tunneling Protocol User Plane (GTP-U) has long been deployed for GSM, UMTS and 4G LTE. Now for 5G, IPv6 Segment Routing (SRv6) has been proposed as an alternative user plane protocol to GTP-U in both 3GPP and IETF. SRv6 based on source routing has many advantages: stateless traffic steering, network programming and so on. Despite the advantages, it is hard to expect to replace GTP-U by SRv6 all at once, even in a 5G deployment because of a lot of dependencies between 3GPP nodes. Therefore, stateless translation and co- existence with GTP-U have been proposed in IETF. However there are no suitable measurement platform and performance evaluation results between GTP-U and SRv6. In particular, it is hard to measure latency on commercial traffic generators when a receiving packet type is different from a sending packet type. In this paper, we focus on the performance evaluation between GTP-U and SRv6 stateless translation. We designed an SRv6 measurement platform using a programmable switch, and measured GTP-U and SRv6 functions with pre-defined scenarios on a local environment. Well-known performance metrics, such as throughput and packets per second (PPS), are measured by the traffic generator while the latency at the functions was measured using telemetry on our SRv6 platform. In our evaluation, we cannot find the abrupt performance drop of well-known metrics at SRv6 stateless translation. Moreover, the latency of SRv6 stateless translation is similar to GTP-U and their performance degradation is negligible. Through the evaluation results, it is obvious that the SRv6 stateless translation is acceptable to the 5G user plane.

There is a pressing need to distribute accurate timing, i.e., frequency and/or Time of Day (ToD), across Packet Switched Networks (PSNs) for applications such as cellular backhaul. This paper reviews the main issues involved in timing over packet (ToP) demarcation and provides best practices for ToP demarcation and performance monitoring.
Teleprotection signals from protective relays are among the most critical data transmitted across utility networks, as they help manage the power grid load, as well as to protect equipment within the power network from severe damages resulting from faulty HV lines. By enabling load-sharing, grid adjustments and immediate fault clearance, Teleprotection has a decisive role in ensuring uninterrupted power supply and therefore requires special attention with regards to network performance and reliability. Specifically, protection commands must be assured immediate delivery when problems are detected, so that faulty equipment can be disconnected before causing a system-wide damage.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
