eCall Plugtests™


Scope & Technical Details


The event will focus on testing interoperability of the Pan European eCall. An event not to be missed, if you want to be sure your products and implementations are fit for the upcoming eCall market!

Interoperability test process

The goal of interoperability testing is to check that devices resulting from protocol implementations are able to work together and provide the functionalities provided by the protocols. As necessary, one message may be checked during a test, when a successful functional verification may result from an incorrect behaviour for instance. Detailed protocol checks are part of the conformance testing process and are thus avoided during the Interoperability tests.

The test sessions will be mainly executed between 2 devices (IVS and PSAP eCall modem-server) from different vendors.

In addition to the 7 mandatory interoperability tests, 21 other ‘optional’ tests have been spectified, and these may be used to help diagnose basic call set-up problems and high level application protocol (HLAP) timing issues that may be encountered during the interoperability testing phase.
For some of the optional tests it is necessary to use a mobile phone instead of the IVS and in other tests to replace the PSAP eCall modem-server with a telephone.

Testing architecture

The test site architecture comprises a private GSM & 3G mobile network and MSC. A SIP (VoIP) trunk from the MSC gateway connects to a SIP – ISDN media gateway providing 8 VoIP channels and 4 x E1 / ISDN (PRI) interfaces. ISDN BRI could be configured if required.
