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

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?

CBC Conformance Testing and Interoperability Issues

• Interface 3

• Standardisation of CBE interface

• Has Great advantages

• Priority of this is questionable

• Sharing of XML technology ?

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
