MMTel AS and SCC AS is starting to use the AS generic SIP port instead of using dedicated SIP ports for each session case and registration state.

The use of the AS generic SIP port requires that the Application server trigger in HSS includes the AS name in the trigger. The AS name is added in the Route header in the ‘as=’ parameter.

Example for MMTel AS:

Route:< sip:mtas.operator.net; as=MMTelAS; lr >

and for SCC AS:

Route:< sip:mtas.operator.net; as=SCCAS; lr >

To be able to determine the session case and reg state the P-Served-User header must be included in the SIP request.

The AS generic SIP port is also handling the PSI functionality over the MA interface. In this case the AS name must not be included in the Route header.

The currently used AS choosing algorithm, based on the configured ports, is deprecated now.

Description of cause 1: The outgoing connection setup and bind the eVIP address with any free ephemeral port, which shall be available at the cluster level for processors. If no ports are available in the cluster, the alarm is issued with processor-specific information. When the binding failed in a different processor, the alarm is updated accordingly.The alarm ceases when the ephemeral ports are available again at the cluster level during a new TCP outgoing connection are setup successfully.

• Cause 2: SIP outgoing connections via TCP timed out. Description of cause 2: If there is no response from the peer for the SYN request sent by MTAS when attempting to set up an outgoing SIP connection to the peer, for example, CSCF, then the connection request times out. The alarm ceases when new SIP outgoing connections are set up successfully.

OCB service of MMTel AS can use the PLMN ID from PVNI header in incoming INVITE as additional input to roaming state check.

MTAS Improvements to S8HR roaming

ICB

No impact

ICB service of MMTel AS can use the PLMN ID from stored PVNI as additional input to roaming state check.

MTAS Improvements to S8HR roaming

Charging

No impact

Online charging service of MMTel AS can use the PLMN ID from PVNI as additional input to disable Ro signalling towards charging system if the terminating call ends with UE located in HPLMN

MTAS Improvements to S8HR roaming

Northbound Call Control

No impact

Northbound Call Control service of MMTel AS can use the PLMN ID from PVNI as additional input to disable CAP T-CSI invocation towards SCF system if the terminating user is located in HPLMN.

SSC announcement handling for OCB operations.

SSC

Minor impact

Enhancement to the SSC service which allows playing the detailed announcements on OCB BP activation, deactivation and interrogation alternatively to the existing announcements in the design base.

HV78946

SSC

ISC

No Impact

Six services with SSC codes do not enforce SSC service to be subscribed before allowing use of SSC code. This TR fix introduces six new CM attributes, one for each service, which makes it possible to enable check on SSC Service subscription before allowing use of SSC code. If enabled, use of SSC will be prevented in case SSC is not subscribed. Default is legacy behavior. The following CM attributes are added: mtasSscVmEnforceSscSubscribe, mtasSscCellAnnEnforceSscSubscribe, mtasSscPriorityCallEnforceSscSubscribe , mtasSscAbDialEnforceSscSubscribe , mtasSscCrEnforceSscSubscribe, and mtasSscHotlineEnforceSscSubscribe.

HV74386

FCD

ISC

Minor Impact

Because of an earlier fault FCD service was not adding a mobile terminal selector in the outgoing INVITE for the PRIMARY_MOBILE when configured in mtasFcdAdditionalTermSelectorMobile. Now FCD service will include it.

HV61332

User Location

ISC

Minor Impact

Because of an earlier fault at User Location Service MTAS removed the PIDF+XML (Presence) MIME part within the body included in the received INVITE, if it is not in addr-spec format. Now MTAS will reject such requests with 400 Bad request. In case of response message the session will be terminated.

HV81300

Gateway Model

ISC

Minor Impact

The Gateway Model service removes precondition attributes in SDP of INVITE before forwarding the request when 'precondition' tag is not present in Supported/Require header.

HV91603

CC

Mp, Mr

Minor Impact

The measure of CM attribute “ mtasCcInbandInvocationTimer” is seconds (see: [6]). It is stored in an internal object in milliseconds. The original value was multiplied by 100 by mistake. Now it is corrected. Consequences: - Using the internal interface (Mp): no change in duration and ‘to’ values as they need to be sent in 10 ms granularity, however ‘mrt’ and ‘wit’ values were sent out in miliseconds, now it is corrected and they are sent out in 10 ms granularity as standard says they need to be. - Using the external interface (Mr): operator might experience duration values being 10 times longer than before in CC scenarios. In case the service fills our internal object with “duration” value, we start a timer. Previously it was started with “duration” × 2, it has been changed to “duration” + 2 seconds. (If MRF does not react before this timer expires MTAS will send a BYE towards it.)

HV88319

Communication Barring

ISC

Minor Impact

The Communication Barring service tries to extract MCC from any access-info key-value of PANI header before returning MCC extraction failure result.

HV67706

FIP

Rf

Minor Impact

For specific FCP/FIP service interaction case as described in HV98521, FIP AVP will not be reported anymore in ACR STOP.

HV94744

Northbound Call Control

ISC

Minor Impact

If the call is rejected or released by CAP ReleaseCall (RC) message, the warning text in rejection or BYE will be updated to “Release Call received from CAP”. If the call is released by ACH.ReleaseIfDurationExceed, the warning text in BYE will be updated to “Credit limit reached”.

HV16088

Communication Barring

ISC

No Impact

New CM attribute mtasCbVersion: This attribute defines the version of the Communication Barring service used when set to 0 ( INITIAL_VERSION) legacy behaviour of the service will be active i.e Communication Barring Service is not forced to add a warning header to each rejection case. when set to 1 ( VERSION_1) Communication Barring Service is forced to add a warning header to each rejection case.

HV91894

IdPres

ISC

Minor Impact

from-change options tag re-inserted by user in subsequent in-dialog signaling is removed (that is, EARLY_UPDATE, INVITE_ACCEPT, ReINVITE + UPDATE and ReINVITE_ACCEPT+ UPDATE_ACCEPT).

HV96929

Hold/OCT

ISC

No Impact

Current implementation for SDP offer in INVITE for end-point move was, The MMTel AS shall re-use the last SDP offer from the caller when an initial INVITE is sent to (new) target. MTAS has implemented this requirement. Call flow in the TR shows that the OT is putting User A on hold. So OctService is picking the last SDP (SDP in 200OK from User A for the HOLD Invite) and sending it to USer C. This SDP contains 'recvonly' which will be rejected by User B. The TR was solved by making to use the last SDP from User A in the HOLD sequence and modify the media direction in SDP to sendrecv.

HV59547

FIP

ISC

Minor Impact

Because of an earlier fault, Originating MTAS was not changing FROM/PAI according to FIP provisioning data in Unregistered case as it should. This issue is now fixed

HV62178

Adhoc Conference Service

ISC

Minor Impact

Because of an earlier fault, MTAS was not able to answer messages with ill-formed Tel-Uri in the Refer-To header. Now MTAS is answering with code 416 Unsupported URI Scheme with warning code and "Invalid URI format." warning text.

HV70143

FIP

Counter

Minor Impact

Because of an earlier fault, the MtasIdPresFip counter was not incremented when MsnFip was invoked, only when Fip was invoked. Now MTAS is increasing the counter in MsnFip cases as well, so increased counting is possible, if MsnFip is used.

HV61985

Adhoc Conference

ISC

Minor Impact

Because of an earlier fault, Long duration call supervision was not considered, when moving a call to conference. Now MTAS is restarting the Long duration call supervision when a session is moved to conference. See the Multi Media Telephony in MTAS document.

HV64259

Number Normalization

ISC

Minor Impact

Because of an earlier fault, Number Normalization was not applied for Tel-Uris which contained SSC with #. Now MTAS will apply Number Normalization to those Tel-Uris as well.

HV48535

FCD

ISC

Minor Impact

Because of an earlier fault, FCD Service did not put 100rel into the outgoing REINVITE messages. Now FCD Service is adding 100rel into the outgoing REINVITE messages into the Supported header.

HV51184

DEN

ISC

Minor Impact

Because of an earlier fault, in case of an active DEN subscription, MTAS could not handle calls after the client was not providing Device identity in the DEN related SUBSCRIBE message. Now MTAS tries to get the Device identity from the earlier sent REGISTER message.

HV60636

ST-AS

Rf

Minor Impact

Because of an earlier fault, in case of originating call from an Invalid PBX subscriber, no ACR is triggered from ST-AS. Now MTAS is sending ACR event in this case

HV64418

Emergency State

ISC

Minor Impact

In case of Emergency Callback call, every owned device was ringing. Now based on mtasEsCbTag the attributes specifies the tag of the top-most Route header to identify an emergency callback call. MTAS classify served user as being in emergency state if the top-most Route header of an incoming INVITE includes the configured string.Default value is empty, which means that no search of Route header is performed. See the FS 'Emergency State in MTAS' for more details.

HV57010

Sip Overload Control

ISC

Minor Impact

Because of an earlier fault, responses for Out of Dialog requests ,other than INVITE and REGISTER, did not contain OC information. Now MTAS is sending OC related info in those responses as well.

HV73662

FSFS

ISC

Minor Impact

Because of an earlier fault, FSF header was removed by MMTService independent on CM mtasFsfPatternRemoveFlag. Now MTAS will not remove, if the mtasFsfPatternRemoveFlag is set to 0=DO_NOT_REMOVE

HV76617

GCAC

ISC

Minor Impact

Because of an earlier fault, at GCAC Service rejection we used "User Call Admission Control" phrase in the warning strings. Now GCAC will use "Group Call Admission Control" instead.

HV49809

3pty

ISC

Minor Impact

Because of an earlier not handled case, during 3pty conference creation the re-INVITE with media mode 'inactive' caused not handled problems at the call, resulting call termination. Now MTAS is rejecting it with SIP 480.

HV74522

AoC

ISC

Minor Impact

Because of an earlier fault, AoC Service was not sending AoC information in the 180 Ringing message. Now MTAS is sending this information.

HV77906

CDIV

ISC

Minor Impact

Minor impact Because of an earlier fault, MTAS forwarded the RTTI related message body from the C-Party to A-Party in a Call Forwarding Unconditional scenario, in the provisional response. Now MTAS is not forwarding the RTTI related message body in this case.

HV74386

FCD

ISC

Minor Impact

Because of an earlier fault, FCD Service did not add configured AdditionalTermSelector if target was PRIMARY_MOBILE and has not been registered. Now MTAS is checking if CM mtasFcdAdditionalTermSelectorMobile has a configured value in this case. If configured, it will add it to the AC header.

HV76242

CDIV

ISC

No Impact

When mtasCdivPostOpRulesBehavior parameter is disabled (its value is 0) CDIV can only forward if both operator ruleset and user ruleset are activated.

When mtasCdivPostOpRulesBehavior parameter is enabled (its value is 1) CDIV can only forward if operator ruleset is activated.

mtasCdivPostOpRulesBehavior parameter is disabled by default.

mtasCdivPostOpRulesBehavior replaces SC-90.

HW24580

SSC

ISC

No Impact

When the CM attribute mtasSscRejectInvalidServiceCodeCommand is set to FALSE, calls will not be rejected due to invalid SSC command. Default value is TRUE in which case legacy behavior applies where invalid SSC command will result in call rejection.

HV97812

STAS

ISC

No Impact

The STAS now supports to transfer a SIP NOTIFY (refer event) that is received inside of dialog as a response to a REFER message previously sent transparently through ST AS in the other direction. The NOTIFY is sent transparently through ST AS.

HW31744

CDIV

ISC

No impact

When mtasStCdivPostOpRulesBehavior parameter is disabled (its value is 0) CDIV can only forward if both operator ruleset and user ruleset are activated.

When mtasStCdivPostOpRulesBehavior parameter is enabled (its value is 1) CDIV can only forward if operator ruleset is activated.

mtasStCdivPostOpRulesBehavior parameter is disabled by default.

HW33031

SRVCC

ISC

Minor Impact

SRVCC service is corrected in general to forward the reason header of BYE/CANCEL from UE on CS to the remote UE after SRVCC transfer.

Details about the five covered scenarios:

• Originating ongoing call transfer: After SCC AS receives AT-INVITE, BYE from CS contains a reason header. SCC AS sends the BYE to the remote user containing the same reason header.

• Terminating ongoing call transfer: After SCC AS receives AT-INVITE, BYE from CS contains a reason header. SCC AS sends the BYE to the remote user containing the same reason header.

• Originating alerting transfer: After SCC AS receives AT-INVITE, early BYE/CANCEL from CS contains a reason header. SCC AS sends a CANCEL (or BYE in some corner case) to the remote user containing the same reason header.

• Terminating alerting transfer: After SCC AS receives AT-INVITE, BYE/CANCEL from CS contains a reason header. SCC AS sends an error response to the remote user containing the same reason header.

• Pre-alerting transfer: After SCC AS receives AT-INVITE, BYE/CANCEL from CS contains a reason header. SCC AS sends a CANCEL (or BYE in some corner case) to the remote user containing the same reason header.

HV98094

Ad-hoc Conference Service

ISC

No impact

During an Ad-hoc Conference it is decided whether the user-entity part of conference info XML of the NOTIFY message has to be anonymous or not according not only to the presence/lack of the privacy header of REFER message but also according to the return value of isMovedInCPAnonymous() function of the AdHocConferenceParticipant object.

HV71205

SIPSFW

Counters

No impact

Fix counter MtasMmtTermUnregServiceDuration, now it can count service execution duration correctly.

HW37628

NCC Service / Ad-hoc Conference Service

CAPv2

No impact

NCC Service has been corrected to not terminate session when receiving ReleaseCall (RC) from CSI in case session is a conference session. It is Ad-hoc Conference service that controls when to terminate a conference session.

HW20725

FCD

ISC

No impact

FCD service changed to not remove provisioned feature tag preference for INVITE sent to the primary target.

HW17822

TADS

ISC

No impact

TADS service rejects early UPDATE coming from remote network during early CS-breakout procedures. Previously such request resulted in Capsule Abortion, now it is rejected with 491 Request Pending.

HW29736

NorthboundCallControlService

ISC

Minor impact

After the call has been established, when NCC receives a ReleaseCall from SCP. then SIPSFW will only put Q850 reason in the Reason header in SIP BYE message.

HW23213

Priority Service

ISC

Major impact

MTAS changes the RPH header handling if the Resource Priority service is enabled. The new behavior is for the both SIP responses and requests originating from MTAS will include an RPH header if it was included in the initial INVITE. Otherwise, RPH header contains if and as it was included in the latest received request on this dialog.

TR HW33693

SRVCC

ISC, Ma

Major impact

If Rel12 charging correlation is enabled (mtasSrvccR12Charging = 1), SCC AS will Store P-Charging-Vector's “icid” and “icid-generated-at” parameters on the source access leg and use them in PCV's “related-icid” and “related-icid-generated-at” that's sent in responses to AT-INVITE.

HW29736

NorthboundCallControlService

ISC, Ma

Major impact

After the call has been established, when NCC receives a ReleaseCall from SCP and generates the TERMINATE_SESSION event, it should only set the 'iQ850RejectReason' parameter as empty string, set 'iRejectReason' as zero, set 'warningString' as empty string. In this way SIPSFW will only put Q850 reason in the Reason header when translate TERMINATE_SESSION event to SIP BYE message

HW39603

SSC Service

ISC, Ma

No impact

SDP with port set to “0” will be included in 200 OK from MTAS for INVITE when external MRF does not respond on request for playing announcement and when Gateway Model is unlocked

HW23213

Priority Service

ISC, Ma

Major impact

MTAS changes the RPH header handling if the Resource Priority service is enabled. The new behavior is for the both SIP responses and requests originating from MTAS will include an RPH header if it was included in the initial INVITE. Otherwise, RPH header contains if and as it was included in the latest received request on this dialog

HV97228

Number Normalization

ISC, Ma

Major impact

The behaviour is corrected to use Default Context in case no context is found for profile in Number Normalization. Although it is not recommended, but still if faulty legacy behavior is needed, it can be achieved using the ENV variable.

SIP P-Early-Media Header Support and early delivery of the SDP answer

Gateway Model Service

ISC, Ma

No Impact

New option added to keep P-Early-Media header support capability of served user

SIP P-Early-Media Header Support and early delivery of the SDP answer

PEM Interworking service

ISC, Ma

No Impact

New P-Early-Media Interworking service added

HW44703

CAP

Mp

No Impact

Prior to this version CAP to Megaco mapping of Interruptable announcement was incorrect. Now the Boolean is negated (as it should have been done before)

HW31458

Gateway Model Service

ISC, Ma

Minor Impact

If the MMTel AS is operating in non-transparent mode and initial INVITE is received with Request-Disposition: no-fork, Gateway Model service accept early UPDATE.

HW53307

CDIVService

ISC, Ma

Mino impactr

Initial INVITE can contain multiple feature tags in Contact header.

Perviously during the preparation of the forwarding INVITE CDIVService checked the Contact header feature tag extensions found in the initial INVITE and removed all except for 3 predefined ones (video, audio and isFocus tags). CDIVService doesn’t remove any feature tags.

Example: Contact header in initial INVITE: Contact: <sip:+16692481015@[fc00:0:12:1284:d45e:bc27:2d43:4d4b]:5060>;+g.3gpp.icsi-ref="urn%3Aurn-7%3A3gpp-service.ims.icsi.mmtel";video;+sip.instance="<urn:gsma:imei:99000704-145023-0>"

Contact header in forwarding INVITE : Contact: <sip:p65548t1513024309m979584c101381s1@[2607:f160:0:1152::2000:3]:5060;transport=udp>;video Contac header in forwarding INVITE : Contact: <sip:p65548t1513024309m979584c101381s1@[2607:f160:0:1152::2000:3]:5060;transport=udp>;+g.3gpp.icsi-ref="urn%3Aurn-7%3A3gpp-service.ims.icsi.mmtel";video;+sip.instance="<urn:gsma:imei:99000704-145023-0>"

HW50536

Adhoc Conference

-

Minor impact

When vtas/mtasConfVersion is zero, partial notification to CC is not delayed. This setup could cause race condition between explicit and implicit notifications towards conference creator. If CM parameter is set to 1 (default) partial notify will be delayed with 1 sec.

HW56944

SSC Service

-

No impact

A failed supplementary service code command, when early media is not allowed (mtasSSCodesPlayEarlyMedia == false), will be responded. If mtasSscRejectFailedServiceCodeCommand is false (default value), the INVITE will be responded with 200 OK and a negative announcement will be played. If attribute is true, the INVITE will be responded with 3xx/4xx (REJECT) and no announcement will be played.

HW62511

OIR and FIP

-

Minor impact

Because of an earlier fault, when OIR and FIP services were both invoked for the very same call, the Privacy=history parameter in History-Info headers were duplicated. Now that error is fixed, so in these cases only one will be sent.

HW64049

SSC and DNM services

-

No impact

Previously it might happen, that with special configuration DNM and SSC codes might overlap, and maybe not the wanted behavior was taken place. Since in our service chain SSC Service is before DNM Service, in overlapping cases always SSC was triggered.

Now there is a new possibility to configure a minimum length for the ND part of the SSC calls, which is triggering SSC. If the minimum length is not reached DNM Service will have also a chance to be triggered.

See mtasSscMinLenOfNdNum.

HW12803

CDiv and CPC services

-

Minor impact

Because of an earlier fault, Supplementary-Service-Identity was not included in ACR start for CPC service, if CDiv service was also triggered. Now it is added.

HW63921

NCC

-

Minor impact

When configured to update the number and the display-name, privacy header in the incoming SIP INVITE and Address Presentation Restricted indicator in CAPv2 CON message is checked. Only in case of both privacy settings are “allowed”, updating PAI and FROM headers are performed. The updates are done regardless a new destination number is received in CON or not.

HW66668

TelSessionService

-

No Impact

Because of an earlier fault MtasMmtInit*SessNOkService counter was stepped every time the call has been rejected due to internal reasons. Now with this fault fixed, changed counter measurements might be seen.

HW38622

Charging

UC Mobility

-

2 New AVPs have been introduced for the UC mobility feature in the Charging Subsystem: UC-Mobility-Call-Leg and Subscriber-Type. Both of them are added to the default omit lists.
