1. New Features

This section lists the features added from the previous release, eCall InBand Modem Library 1.1.1.

Minimum Set of Data binary consolidation: A new API and an AT Command enable end user to benefit from a coder to create the binary format of MSD needed to be sent during eCall process to PSAP.

Note: eCall InBand Modem Library implements the 3GPP InBand Modem feature.

3GPP eCall signaling options for emergency call are available with recent firmware starting from R7.44, including R7.47

A PSAP basic test server has been developed by Sierra Wireless for simple PSAP operation / testing. The PSAP Test server application is available in the package.

4. Interface modifications

This section lists the interfaces that have been modified since eCall InBand Modem Library 1.1.1. For more information about the updated interface, please refer to the documentation provided in the eCall InBand Modem Library package.

API Comment
EncodeMSDMessage This API encodes the MSD data structure to binary MSD coded with ASN1 protocol
eCallMessage_t The eCallMessage_t structure corresponds to the MSD structure provided by CEN [3] with the following implementation.
AT+ASN1MSD This AT Command is used to update MSD parameters fields and generate a binary MSD coded with ASN1 protocol

5. Corrections & Improvements

Id Description (What/When) Impacted Domain Impacted Subdomain Fixed in
61237 INBMPUSH is discarded when previous e-call is released by reception cleardown SAMPLE OTHER 1.1.1
58410 In HR and FR audio coding scheme MSD transfer success rate is very low LIBRARY OTHER 1.1.0

6. Memory requirements

The IVS_Sample application binary size is 112kB for RVDS compiler use.
