osmocom.gsup

GSUP protocol (Osmocom TCAP/MAP alternative)

This is an encoder/decoder implementation for the Osmocom GSUP protocol, built upon the osmocom.tlv and osmocom.construct infrastructure.

class osmocom.gsup.message.GSUP_TLV_IE(**kwargs)

Class representing the TLV format as used in Osmocom GSUP. It’s a simple ‘8-bit tag / 8-bit length / value’ variant.

class osmocom.gsup.message.GsupMessage(msg_type: MsgType | int)

Represents a single message within the GSUP protocol.

classmethod from_bytes(encoded: bytes) → GsupMessage

Create a GsupMessage instance from the decode of the given bytes.

classmethod from_dict(decoded: dict) → GsupMessage

Create a GsupMessage instance from the decoded dict.

to_bytes()

Encode a GsupMessage instance into bytes.

to_dict()

Encode a GsupMessage instance into a json-serializable dict.

class osmocom.gsup.message.MsgType(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)

GSUP protocol message type. Keep this in sync with https://gitea.osmocom.org/osmocom/libosmocore/src/branch/master/include/osmocom/gsm/gsup.h

class osmocom.gsup.message.tlv

TLV definitions for the GSUP IEs, utilizing the osmocom.tlv code. Keep this in sync with https://gitea.osmocom.org/osmocom/libosmocore/src/branch/master/include/osmocom/gsm/gsup.h
