Exploring CBC Conformance Testing and Interoperability Challenges in Mobile Networks

This document addresses critical issues related to CBC conformance testing and interoperability in mobile networks. It discusses team members from various telecom companies and outlines the challenges faced with Base Station Controllers (BSC), handsets, and SIM configurations. Key points include the need for standardization in CBC download support, storage of CBC profiles, and unintrusive message reception. The document emphasizes the importance of collaboration among manufacturers and better access to standards and testing facilities for improved performance and quality in mobile services.

Presentation Transcript

  1. CBC Conformance Testing and Interoperability Issues • Team Members • Neil Mcgrath – Logica Mobile Networks • Paul Curren – Logica Mobile Networks • Walter Kokert – DT-T-Mobile • Stephane Lecherq – France Telecom • Fuad Yatim – Celcom • Ronen Daniel – Celltick • Alan de Vires - CMG

  2. CBC Conformance Testing and Interoperability Issues Handset / SIM 1b 1 2 UE CBC BSC 4 3 SMSC Web Page CBE 4

  3. CBC Conformance Testing and Interoperability Issues • Interface 1 – Base Station Standards • Communication with BSC manufacturers is required • Conformance Testing normally occurs using BSC simulators, or Test BSCs or at the Customer Site • Cost of BSC activation for CBC is questionable, as is the quality of some BSC configurations. • There are some performance issues with BSCs • We need buy in from the manufacturers to CBC. • We need better access to standards and testing facilities

  4. CBC Conformance Testing and Interoperability Issues • Interface 2 – Handset / SIM issues • Need for CBC download support to be standardised • Storage of CBC profiles of the SIM made standard (channels etc) • Un-Intrusive Receipt of Class 2 Messages as standard • The need for a published list of CBC compliant handset / SIM combinations • Question to Handset manufacturers : what sort of resources are they willing to commit to standardisation of CBC? Will it be a ride along?

  5. CBC Conformance Testing and Interoperability Issues • Interface 3 • Standardisation of CBE interface • Has Great advantages • Priority of this is questionable • Sharing of XML technology ?

  6. CBC Conformance Testing and Interoperability Issues • Interface 4 – OTA standard Behaviour • Again – a handset / sim issue • Very important for premium channel distribution • More Testing / Test Results required
