This complete source features a designated method for assessing, examining and optimizing End-to-End provider functionality less than diversified mobile applied sciences (GPRS, side, WCDMA and CDMA2000). It comprises directions for interpreting a variety of various providers, together with FTP, net streaming and POC, together with examples of research and troubleshooting from a consumer point-of-view.

  • Focuses at the end-user viewpoint, with a close research of the most assets of provider functionality degradation and a complete description of cellular information providers
  • Includes an in depth presentation of wide-spread key functionality symptoms (KPIs) which are re-defined to conform with each one specific community
  • Provides provider functionality benchmarking for various applied sciences from genuine networks
  • Explores a brand new method of carrier administration referred to as buyer event administration, together with the explanations why it really is overcoming conventional carrier administration and its impression on sales and buyer pride
  • Illustrates all issues all through utilizing genuine international examples gleaned from state-of-the-art learn

This publication attracts jointly findings from authoritative resources that might attract mobile community operators and owners. The theory-based, useful technique should be of curiosity to postgraduate scholars and telecommunication and consulting businesses operating within the box of mobile technologies.Content:

Example text

Longer RLC transmission windows, which reduces the probability of stalling. 4 (E)GPRS Performance The performance of the (E)GPRS connections is very much dependent on the radio conditions (C/I) and on the available resources for data calls (PDCH). The radio conditions will determine what coding scheme shall be used, as well as the number of retransmissions that will be caused due to bad radio reception. In addition, dimensioning of the network may also force users to share the same TSLs, and the available bandwidth, when traffic load grows.

Four different classes are defined in the standard: conversational, streaming, interactive and background (see Chapter 4 for further details). • Mobility management: During an active data transfer, the serving cell may change without an interruption on the TBF. A cell change can be triggered at the mobile station (autonomous cell reselection) or at the network side, based on measurements sent from the terminal (network controlled cell reselection). Unlike GSM voice service, the cell reselection is a blind procedure, meaning that the mobile releases the resources in the serving cell before being allocated new resources in the target cell.

HC – is needed in order to provide mobility across the network, supporting robust transitions between cells. HC decides the set of Node-Bs the UE should be connected to. Such decision can be based on coverage and/or load reasons, and is normally aided by pilot quality measurements conducted at the UE. In UMTS, a UE can be connected to several Node-Bs at the same time via SHO, which provides macro and micro diversity protection and guarantees a smooth transition between cells. AC – is responsible for controlling the load of the system so that the available capacity can be exploited without compromising the system stability.
