Tcl Parameter : UeRegStart

Tcl Parameter : Ve911UeRegStart

Select to enable the Multimedia Priority Service (MPS).  In order for initiating a priority call, an originating UE needs to include a SIP Resource-Priority header with its outgoing INVITE requests; and, a core network will decide whether such calls are allowed based on current resources. Originating UE could include multiple priority levels for a same or different namespaces (Per RFC 4412).  A priority level is text string consisting of a namespace and a level separated by a dot such as “wps.4”.  Multiple levels are allowed and they are separated by a comma and a space such as “wps.4, wps.3”.  

By default, this input text box is set to “wps.4” for indicating priority level 4 of the “Wireless Priority Service” namespace.

The WPS namespace derives its name from the "Wireless Priority Service:, defined in GSM and other wireless technologies. The  WPS namespace defines the following resource values, listed from lowest priority to highest priority:

(lowest)  wps.4

               wps.3

               wps.2

               wps.1

(highest) wps.0

RFC 4412 specification defines five unique namespaces : DSN, DRSN, Q735, ETS, and WPS, constituting their registration with IANA. Refer to RFC for additional details.

Tcl Parameter : UeMpsMandatoryEn

Tcl Parameter : Ve911UeMpsMandatoryEn

Available in SGW Nodal and Wifi Offload Gateway Nodal test cases. Enables the OTT Access Auth Tab under the Gm Interface.

The difference between native VOLTE Client and RTT OTT Client can be summarized as following:

• RTT OTT Client and native VOLTE Client use different APNs
• Native VOLTE Client’s Public and Private Identities are provisioned on LS GUI (Phone Book). RTT OTT Client receives its Public and Private Identities from the network during user authentication process.
• RTT OTT has to initiate user authentication against API GW using HTTP/HTTPS protocol prior to IMS registration. This authentication is based on OAuth authorization framework defined by RFC 6749.
• As a result of OAuth RTT OTT Client receives
  • IMPU (Public User ID) that will be used instead of the one that is configured on GUI;
  • IMPI (Private User ID) that will be used instead of the one that is configured on GUI;
  • SBC FQDN: usually SBC FQDN has to be resolved by DNS and used as SBC/P-CSCF IP address. To simplify it Landslide VOLTE solution has P-CSCF IP address configured on GUI.

Tcl Parameter : UeOttAuthEn

Tcl Parameter : Ve911UeOttAuthEn

Available in AMF Nodal, IP Application Node and MME Nodal test cases. Enabled when Supplementary Mode is turned on. Select for Government Emergency Telecommunications Service (GETS) KPIs to be reported to the TEST.PROCS file. 

This is a licensed feature. The GETS Feature requires POLQA to be enabled and UE Info Level set to 10 for the Test Server assigned for AMF Nodal and MME Nodal (MO and MT).

The TAS has been enhanced to record the announcements which are compressed to tar.gz and become a part of the "Test Results" when Enable GETS Analysis is enabled. Storing the announcement for GETS core call aids in the assessment of call failure conditions. 

1. Once a test is completed, all the .wav files belonging to that particular test session can be found at /home/spcoast/sNNNN/tsNNN where NNNN is the RID number . 
2. ALL the .wav files from /home/spcoast/sNNNN/tsNNN are compressed to tcIndex_announcement.tar.gz. and saved at /home/spcoast/sNNNN/tsNNN where TAS can retrieve based on the file extension. 
3. The wave file is compressed to tcIndex_announcement.tar.gz. The TAS adds the STARTTIME_RID_tsN_ prefix.   (Example:  21-01-21_22_24.27_RID-281_tc0_announcewav.tar.gz). 
4. The wave file itself is named tsN_tcN_ueN_subN_stream_N.wav, tsN where N is the test server number, where N is the test case index, ueN where N is the UE Index, subN where N is the subcriber index, streamN where N is the RTP stream number.
5. Limitation / Caveat : Test Server must be configured with Legacy mode and POLQA resources, Fireball not supported, No UE specific index for this release, Turn on "Do not delete temp files", Turn on Per Session results. 

The user can open the compressed file to get their .wav file from test results.

The GETS KPIS are :

GETS VOICE_TONE_RECEIVE_FAILURE - Voice tone was not received

UE_VOLTE_GETS_PIN_FAILURE - GETs PIN error message was not recognized

UE_VOLTE_GETS_DEST_ NUM_PLAY_FAILURE - Playback failure “Please enter your destination number now"

UE_VOLTE_GETS_PLAYBACK_ FAILURE - Playback failure “You are using GETS xxxxx”

Tcl Parameter : GetsAnalysisEn

Available in AMF and MME Nodal test cases when Enable Registration and Calls Start After = " When All Users Registered".

When Enable Registration Failed Threshold is enabled, even if all Sessions are not established, if the PDN Failed Threshold (%) percentage on MME Nodal or Registration Failed Threshold (%) on AMF Nodal or PDU Failed Threshold (%) percentage on SMF Nodal, is within this limit, SIP Registration will be initiated for rest of the established PDUs. Otherwise when not enabled, if the Traffic Start pattern chosen is "When All Session Established", only when all the PDU are established VOLTE will start Registration. 

Similarly in case of Volte Call, if the Call Start pattern chosen is "When All User Registered", however even if all Sessions are not Registered, if the Registration Failed Threshold percentage is within the limit, SIP Call will be initiated for rest of the registered UEs. 

On AMF/MME/SMF Nodal VOLTE tab to support Registration Failed Threshold percentage, there are 2 layers of thresholds :

• a threshold for the SIP registers (Enable Registration Failed Threshold (%) and  percentage based on the pdu established UEs (PDN Failed Threshold (%) percentage on MME Nodal or Registration Failed Threshold (%) on AMF Nodal or PDU Failed Threshold (%) percentage on SMF Nodal) 

Example :
1000 UEs are configured 
50 failed to establish a pdu (or PDN for MME nodal)
your threshold is 10% , threshold not exceeded 
thus 950 will continue to register

Example : a threshold for the SIP invite, percentage based on the SIP registered UEs 
1000 UEs are configured 
50 failed to SIP register  
your threshold is 10% , threshold not exceeded 
thus 950 will continue to send invite 

Range : 0 to 100

Default : 10

Tcl Parameter: UeRegFailThreshPctEn

Tcl Parameter: UeRegFailThreshPct

Available in IP Application Node, MME Nodal, PGW Nodal, SGW Nodal and Network Host (server DMF only) test cases when Enable Supplementary is selected. Enables the OIDC User Auth Tab under the Gm Interface.

Select for UE authentication for Mission Critical Push-to-Talk (MCPTT) as specified in the 3GPP TS 23.280, 22.179, 23.179, 24.379, 24.380, 33.179, 24.382, 24.384 specifications, OpenID Connect 1.0, and IETF RFC 6749 (OAuth 2.0).

Mission Critical Push-to-Talk (MCPTT) is one of important technologies that helps to enable the public safety broadband network proposed by First Responder Network Authority (FirstNet).

MCPTT is one of the services under the 3GPP Mission Critical Services (MCS) framework. All of the MCS utilize the MC core provided by 3GPP networks to enable MCS subscribers to communicate with fast setup times, strong security and priority handling. MC services include MCPTT, as well as MC Data, MC Video, etc. These services are provided in two modes, On-network, which is using E-UTRAN and EPS bearers, and Off-network, which is using public safety Proximity Services (ProSe).   

MCPTT client is authenticated and authorized for MCPTT service through interfaces between identity management, key management, group management clients (reside in MCPTT client) and identity management, key management, group management servers in Common Service Core (CSC). This feature focuses on the interface CSC-1, which is between identify management client and identity management server. Please see the following diagram from 3GPP TS 23.280.

Landslide is emulating MCPTT clients, SIP core, and MC service domain. Identity management client is part of MCPTT UE. However, Identity management server is part of CSC and a logic function outside of MCPTT server. Identity management server (or the HTTP proxy in the same domain as the IdM server) can be emulated by a separate Network Host test case with Landslide DMF:

OAuth is a widely-used authorization framework based on HTTP. It allows applications to access resources on other servers in a secure and efficient way, without passing credentials from the resource owner to the third-party applications directly. Instead, it obtains tokens from the resource owner, and using the tokens to access the protected resource for a specific scope, lifetime, and with other access restrictions.

OpenId Connect ((http://openid.net/connect/faq)) is a thin layer built upon OAuth 2.0 to enhance the flows to perform authentication properly.

Tcl Parameter : UeOidcAuthEn

Floor control is used to determine which subscriber has the authority to talk at a certain time during an MCPTT call. Please refer to 3GPP TS 23.179 for floor control commands and procedures, and 3GPP TS 24.380 Clause 8 for floor control protocol over RTCP. We will support the following commands : Floor Request, Floor Granted, Floor Idle, Floor Release and Floor Taken and procedure "Floor Request, Floor Granted and Floor Taken during an MCPTT Session".  several new SIP Built-in Actions and two new SIP Built-in Scripts are available for Floor Control.  

Landslide test cases are acting as MCPTT UE, SIP Core and Application Services layer.

An MCPTT private call is between two users. An MCPTT group call is between several users, where each user has the ability to gain access to the permission to talk in an arbitrated manner. TS 24.379 Landslide will provide means to emulate both types of the calls. Two new SIP Built-in Scripts are provided for the following two types of flows. One is private call with floor control (MCPTT Private Call with Floor Control) and the other is prearranged group call (MCPTT Group Call with Floor Control). In addition, several new SIP Built-in Actions are provided :

Tcl Parameter : SipDeregRate

Available on IMS Nodal when ISC Interface is enabled. Enable for support of third party registration. 3rd Party registration involves encapsulating the SIP REGISTER and 200 OK messages exchanged between P-CSCF and I/S-CSCF as message body in the SIP REGISTER sent from S-CSCF to SCC-AS. This is a licensed feature.

Third-party REGISTER request and 200 OK will be embedded as a message body.  

Tcl Parameter : Sip3rdPartyRegEn

If enabled, REGISTER message will be sent continuously on a timed basis. After first successful REGISTER, timer will start and subsequent Register messages will be sent based on timer value. Timer value is calculated by:

Example to calculate the time value:

Registration Rate = 50/sec

Number of Mobile nodes = 100

Case 1: Sip subscriber per UE=1

TimeValue in milli secs = (Number of Mobile Nodes X Sip subscriber per UE X 1000) / Reg Rate

                                     = 100 X 1 X 1000/50

                              = 2000 ms = 2secs

Case 2: Sip Subscriber per UE=2

TimeValue in milli secs = (Number of Mobile Nodes X Sip subscriber per UE X 1000) / Reg Rate

                                     = 100 X 4 X 1000/50

                              = 4000 ms = 4secs

Tcl Parameter : Ve911UeSessionExpires

Available when Session Expires is enabled on VoLTE - Call Info Panel and on IMS Node Emulator Cnfg.

Select to initiate the SIP UPDATE message from a MT VoLTE SIM Server at the expiration of the Session-Expires timer.

Refer to RFC 4028 - The Session Expiry Timer is a SIP Session specific mechanism for Call parties and optionally Proxies to be sure that opposite side of the Call is alive. During a Call Session one of the side, Caller (UAC) or Callee (UAS), sends re-INVITE or UPDATE message and other side of the Call confirms it by sending 200 OK. An example of the SIP Session expiry flow diagram is shown below:

The SIP Session Timer Expiry negotiation is accomplishing during initial Call Setup.

MO (User A for the given example) sends INVITE that conveys:

1. Header Supported: with value "timer", that means the side does support the Session Timer Expiry
2. Header Session-Expires: with the Expiry interval value (120 seconds for the given case) and optionally refresher with two optional values: UAC or UAS. The fact, that it is missed in the given example means that it is to User B to decided who will be doing the periodic refreshing updates: UAS or UAC.

MT (User B) in 200 OK to INVITE provides the result of the negotiation it is willing to take:

1. Header Supported: with value "timer" means that User B is also supports the Session Timer Expiry.
2. Header Session-Expires: refresher = UAS and Timer Expiry interval of 90 means that UAS side (User B for the given example) will be in charge of sending periodic expiry updates. User B haven't accepted the expiry interval of 120 seconds and changed it to it's own setting: a lower value of 90 seconds.  

SIP sides should negotiate who is making SIP session refreshing: MO or MT, during Call Setup:

• INVITE ' Session-Expire header suggests UAC, UAS, or none
• 200 OK'  Session-Expire header contains who is actually is the refresher: UAC or UAS.

Originator Mode - Select NONE, UAC or UAS.

Terminator Mode - Select NONE, UAC or UAS.

Tcl Parameter : ImsNodeRefresherOrigMode

Tcl Parameter : ImsNodeRefresherTermMode

Tcl Parameter : UeRefresherOrigMode

Tcl Parameter : UeRefresherTermMode

If enabled, re-send the INVITE message through TCL events. The TCL events will be generated for a range of subscribers (calculated based on the desired call rate), and INVITEs will be sent for these subscribers. In the next iteration, a new range of subscribers will be generated and the INVITEs will be sent accordingly. This process of continuous and looped TCL triggers will be started only after the test case has gone through the expected initial registrations and INVITEs. Once the regular INVITE's have been triggered at the TCL level for all subscribers, only then will the constant call traffic be triggered at the TCL level.

Set Call Starts After to "When All Users Registered".

Fully controlled through events generated at TCL.

Not supported for Supplementary Services and SIP Endpoint Mode.

Registration retransmission mechanism shown below , leverage this feature for UDP. The retransmission interval is calculated as:

T([n+1]th-interval) = MIN(2^n * T1, T2)

For example, 1st retransmission interval will be MIN(T1, T2), 2nd retransmission interval will be MIN(2*T1, T2), 3rd retransmission interval will be MIN(4*T1, T2), and so on.

Retransmission will be exhausted in the case of either

• Number of retransmission reaches max number of retransmission, or
• Total retransmission time, which is T(1st-interval) + T(2nd-interval) + T(3rd-interval) + ... exceeds max request transaction time

• Allow Events :  Specify a list of supported/allowed events.  Currently, Registration event as specified in RFC 3668 is supported.  When IMS-Node receives subscribe request for an event included in this allowed list (i.e. reg), it will handle the request and generate notification as specified in the listed specification. (i.e. send notification when there is a change in registration state, aor, contact, etc.).   Tcl Parameter: SipSubEventRegEn
• Unknown Events : IMS-Node considers a received event is unknown/unsupported if the event value in a request is not in the list of allowed event and will respond to the request based on the following choice
  • Reject : default option. If the reject option is selected, IMS-Node will reject a request with a configured response-code. Enter Response Code : Range 200 to 999. A default response-code is 489 (bad event). Tcl Parameter: SipSubUnkEventAction , Tcl Parameter: SipSubUnkEventRspCode
  • Accept - if the accept option is selected, IMS-Node will accept a request and respond with a 2xx response-code.  NOTE: this option is added for development/interop testing purpose; it should be used with extra care because each subscribed event has its own specification/syntax/procedure.  For example:  dialogue (RFC 4235),  present (RFC 3856,5263), conference(RFC 4575), etc. This option should be used with manual notification.
• Notification - specify how IMS-Node generate notification for subscribed events.
  • Auto - default option. When selected, IMS-Node will generate notification based on change of state/status of resource such as registration state etc. Tcl Parameter: SipSubUnkEventNtfy
  • Manual - When selected, IMS-Node will generate notification message based on a specified interval and count regardless whether there is any change in state/status of subscribed event. This option was added for development/interop testing puropse and it should be used with extra care. For unknown/unsupported subscribed event, IMS-NODE will generate a notify request with empty message-body; users should use the SIP message editor to modify and add correct content to notify requests.
    • Notification Interval (s) - Enter the time in seconds between generated notification. Range : 1 to 65535. Default : 5. Tcl Parameter: SipSubUnkEventNtfyPeriod
    • Notification Count - Enter the number of generated notifications. Range : 0 to 255. Default : 1. Zero (0) is valid and used for not generating any notification. Tcl Parameter: SipSubUnkEventNtfyCount
