HSS Tools

A set of useful tools to generate requests towards EPC or IMS HSS.
Copyright (c) 2015-2017 Denis Gudtsov Project page: https://github.com/dgudtsov/hsstools

Uses part of Python Protocol Simulator project (c) Sergej Srepfler code - https://sourceforge.net/projects/pyprotosim/

The following interfaces and commands are supported:

• Sh: UDR, SNR, PUR
• Cx: LIR, UAR, MAR, SAR
• Zh: MAR

Install

1. download archive
2. unzip in
3. ensure the following directory structure:

./hsstools
|-- conf
|-- lib
|-- log
|-- pyprotosim

conf - where config file is stored
lib - program libraries
log - where log files are generated
pyprotosim - external Python Protocol Simulator tool
4. chmod a+x *.py

Prerequisite

Python 2 version >= 2.6.6
Python 3 is not supported

Configure

Edit file conf/config_diam.py :

1. setup hosts, ports, realms for HSS diameter connection
2. define IMPI and IMPU domains, check IMPU and IMPI formats
3. point out pyprotosim_lib_path to directory where pyprotosim project files are located
   Please note, i already included pyprotosim files into package.

Usage

Sh

Format: ./Sh.py COMMAND MSISDN DATA  
COMMAND: one of UDR, PUR, SNR  
MSISDN: msisdn of the subscriber, without +  
DATA: Data-reference name OR Service-Indicator name of repository data  

DATA possible values are: ['STN-SR', 'MSISDN', 'TADS', 'SRVCC', 'Location', 'IMSUserState', 'LocationAct', 'CSRN', 'CSCF', 'UserState', 'RepositoryData']  
Service-Indicator any that's present in HSS,e.g: MMTEL-Services, IMS-ODB-Information, IMS-CAMEL-Services
OR special value 'ALL' can be used (see below)

Examples:

• to read RepositoryData
  example: ./Sh.py UDR 79999999999 MMTEL-Services
  example: ./Sh.py UDR 79999999999 MMTEL-Services,IMS-CAMEL-Services
  example: ./Sh.py UDR 79999999999 ALL
  ALL means: MMTEL-Services,IMS-ODB-Information,IMS-CAMEL-Services,MMTEL-Custom-Services,CM_SUBPROFILE,RMS_DYNAMIC_DATA

• to request specific data:
  example: ./Sh.py UDR 79999999999 Location

<Sh-Data>
  <CSLocationInformation>
    <LocationNumber>
      xxx=
    </LocationNumber>
    <LocationAreaId>
      xxx=
    </LocationAreaId>
    <VLRNumber>
      <Address>
        xxx==
      </Address>
    </VLRNumber>
    <MSCNumber>
      <Address>
        xxx==
      </Address>
    </MSCNumber>
    <AgeOfLocationInformation>
      52
    </AgeOfLocationInformation>
  </CSLocationInformation>
</Sh-Data>

and then decoded values follows:

decoding LocationAreaId
result (MCC|MNC_LAI_CGI): 250f00_6004_
LocationAreaId xxx= 250f006004
decoding LocationNumber
result (MCC|MNC_LAI_CGI): 400004_5002_
LocationNumber xxx= 4000045002
decoding VLRNumber
result: 1xxxf
VLRNumber xxx== 1970000000001f
decoding MSCNumber
result: 1xxxf
MSCNumber xxx== 1970000000001f

example: ./Sh.py UDR 79999999999 TADS

<Sh-Data>
  <Extension>
    <Extension>
      <Extension>
        <TADSinformation>
          <IMSVoiceOverPSSessionSupport>
            1
          </IMSVoiceOverPSSessionSupport>
          <RATtype>
            1004
          </RATtype>
        </TADSinformation>
      </Extension>
    </Extension>
  </Extension>
</Sh-Data>

• to update data
  example: ./Sh.py PUR 79999999999 MMTEL-Services

• How to update user-data with blank value?

1. prepare xml profile without ServiceData element, like:

<?xml version="1.0" encoding="UTF-8"?>
<Sh-Data>
  <RepositoryData>
    <ServiceIndication>YOUR_Service_Indicator</ServiceIndication>
    <SequenceNumber>2</SequenceNumber>
  </RepositoryData>
</Sh-Data>

and save it into file named "YOUR_Service_Indicator". You may don't care about SequenceNumber value, cause it is calculating automatically during update

2. run PUR command:
   ./Sh.py PUR 79999999999 YOUR_Service_Indicator

• How to manage xml profiles?

1. run UDR request, e.g.:
   ./Sh.py PUR 79999999999 MMTEL-Services

new file MMTEL-Services will be created with MMTel xml profile

2. use xmllint tool to pretty format xml and save result into MMTEL-Services.xml:
   xmllint --format MMTEL-Services >MMTEL-Services.xml

3. make changes:
   vim MMTEL-Services.xml

4. convert pretty formated xml into simplified version, back from MMTEL-Services.xml :
   xmllint --noblanks MMTEL-Services.xml >MMTEL-Services

5. run PUR, it will read MMTEL-Services as input data :
   ./Sh.py PUR 79999999999 MMTEL-Services

Cx

Format: ./Cx.py COMMAND IMSI MSISDN [AUTH]
COMMAND: MAR, UAR, SAR, LIR
IMSI: imsi of the subscriber
MSISDN: msisdn of the subscriber
AUTH (optional, only for MAR is required): SIP, AKA, NONE, Unknown

IMPI and IMPU are constructed from IMSI/MSISDN

Examples:

• to request SIP-Digest auth scheme
  example: ./Cx.py MAR 250009999999999 1234567 SIP

• to request Digest-AKA auth scheme
  example: ./Cx.py MAR 250009999999999 1234567 AKA

• to allow HSS select default auth scheme
  example: ./Cx.py MAR 250009999999999 1234567 Unknown

• to request Cx user profile
  example: ./Cx.py SAR 250009999999999 1234567 profile will be displayed on screen and stored into ./data/SAR_UD file

• to request CSCF where subscriber is registered or unreg service for subscriber
  example: ./Cx.py LIR 250009999999999 1234567 server-name or server-capabilities will be displayed on screen

• to request PSI service number
  to request PSI you need to uncomment "Public-Identity" : "{TEL}" in Cx config and comment out "Public-Identity" : "{IMPU}" and User-Name
  example: ./Cx.py LIR 0 1234567
  imsi is not required for PSI

Zh

Format: ./Zh COMMAND IMSI MSISDN [AUTH]
COMMAND: MAR
IMSI: imsi of the subscriber
MSISDN: msisdn of the subscriber
AUTH (optional, only for MAR is required): SIP, AKA, NONE, Unknown

IMPI and IMPU are constructed from IMSI/MSISDN

Examples:

• to request SIP-Digest auth scheme example: ./Zh MAR 250009999999999 1234567 SIP

• to request Digest-AKA auth scheme
  example: ./Zh MAR 250009999999999 1234567 AKA

• to allow HSS select default auth scheme
  example: ./Zh MAR 250009999999999 1234567 Unknown

• The syntax of Zh request are fully equivalent to Cx MAR
  example: ./Cx.py MAR 250009999999999 1234567 AKA
