Overview

The Qualcomm Structure Iteration Language Toolkit (QSILK^TM ) software is a static library that provides Over the Air (OTA) message parsing functionality. The parsing functionality includes unpacking (converting a raw byte stream to a message memory image) and printing messages in text format.

QSILK is intended for users who want to use the QSILK OTA message parser as a static library to parse CDMA, GPS IS-801, or 1xEV-DO messages. Some of the CDMA messages, i.e., SMS transport user data, are defined in the GSM standard. QSILK library is able to parse those CDMA messages based on the GSM standard. It enables tool vendors to save time and resources developing parsers by leveraging Qualcomm for the decoding of CDMA layer 2 and layer 3 standards, and 1xEV-DO signaling standards as well as OTA messages defined in GSM and Bluetooth® standards. For GSM family, we support 3GPP TS 24.008, TS 44.018 and TS 44.060. For Bluetooth, we support LMP, L2CAP and RFCOMM signaling.

Alternatively, if you are developing a tool and do not wish to use QSILK to parse these messages for you, you can use the standards to do this work. The Qualcomm ICDs provide the message capsules containing the raw payloads, but it refers to external standards for payload details for each technology. With WCDMA, a 3rd party ASN.1 decoder can be used, as the payload for WCDMA layer 3 is ASN.1 encoded text.
