New attribute mtasSipRemoveSupportedHeaderInErrorResponse is added to enable MTAS to remove the supported header in SIP response when its value is set to “ 1”. The SIP error responses include these SIP responses forwarded or triggered by MTAS. The error codes of these SIP error response must be greater or (equal to) 300. When the value of parameter is set to “ 0”, the Supported headers are not removed by MTAS if there in these SIP error response as legacy. After upgrade, the default value(“0”) of the CM attribute will be used, that is,. the legacy behavior will be kept.

ISC

SIP

No Impact

New CM attribute mtasSipChangeRefresherRoleInReinviteAndUpdate is added. This attribute defines the MTAS behaviour of changing the refresher role for reINVITE and normal UPDATE in an exception case. If this attribute is disabled, then when MTAS sends out the reINVITE or normal UPDATE, it will not change the role of refresher parameter which means that it will be same as the previous negotiated result. Enabling the attribute, an exception will occur if the previous negotiated result is the remote side as refresher. In this case, MTAS will change the refresher role to empty, i.e. no refresher parameter in the reINVITE and normal UPDATE. In case that before upgrade, the mtasSystemConstantSC ID 84 is set to 1, then this CM attribute will be set to FALSE and the new behavior will be applied. Otherwise, the default value(TRUE) of this CM attribute will be used after the upgrade, that is, legacy behavior will be performed.

New CM attribute mtasSubsDataRegEventNotifier is added. This attribute defines whether MTAS sends the one-time SUBSCRIBE to SCSCF or ICSCF. The possible values are as follows: - SCSCF: MTAS sends the SUBSCRIBE to SCSCF (default). - ICSCF: MTAS sends the SUBSCRIBE to ICSCF at de-registration and to SCSCF at registration. In parallel, mtasSystemConstantSC ID 83 is deprecated. If MTAS is upgraded from 1.6 or 1.7 and mtasSystemConstantSC is set (presents) then the value of the new CM parameter must be 'ICSCF' on the new MTAS version (4.8/1.8 and above).

ISC

No Impact

CM attribute mtasSubsDataRegEventNotifier has been modified: Before MTAS 1.8, MTAS sends the SUBSCRIBE to ICSCF at de-registration and to SCSCF at registration when mtasSubsDataRegEventNotifier: 1=ICSCF. From MTAS 1.8, MTAS sends the SUBSCRIBE to ICSCF in all cases (at registration, at implicit registration and at de-registration as well) when mtasSubsDataRegEventNotifier: 1=ICSCF.

Description of Changes

HV78946

SSC

No Impact

There are 6 services with SSC codes that doesn’t enforce SSC service to be subscribed before allowing use of SSC code. This TR fix introduces 6 new CM attributes, one for each service, that 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 mtasSscHotlineEnforceSscSubscribe

HV74386

FCD

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

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

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

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

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

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

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

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 and every rejection case. when set to 1 ( VERSION_1) Communication Barring Service is forced to add a warning header to each and every rejection case.

HV91894

IdPres

Minor Impact

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

HV96929

Hold/OCT

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.
