Sentinel IP Short Message Gateway 2.5.1 Changelog

The IP-SM-GW now requests a UE Reachability for IP Notification on certain IMS delivery failures. This behaviour is enabled by default, and is configurable via the IP-SM-GW Shared Configuration.

Updated to Sh Cache RA 1.0.2.1. This newer version of Sh Cache RA supports subscription to UE Reachability for IP via Subscribe Notification Request/Push Notification Request (SNR/PNR) with the HSS.

Added IP-SM-GW behaviour when receiving a UE Reachability for IP Notification via Sh Push Notification Request (PNR) (IPSMGW-645).

Third Party Registration Flows for the IP-SM-GW now issue Ready For SM instruction to the HLR. This is enabled by the new Fetch IMSI Registration and Ready For SM Registration features that run in the REGISTER path (IPSMGW-674)

The IP-SM-GW now uses the MAP ReportSMDeliveryStatus operation as part of the MT Delivery Flows. This involves updates to the PS Delivery and CS Delivery features (IPSMGW-698, IPSMGW-668).

Added the Modify SRI Leg feature (IPSMGW-676). This feature runs after the MAP Proxy feature and prevents proxying of outbound Inform Service Centre messages. It also sets SM-RP-PRI=true in outbound SendRoutingInfoForSM requests. Both of these behaviours are configurable via the feature’s configuration profile.

Updated the IP-SM-GW Routing Information Cassandra schema used for MT Correlation storage to store entire SendRoutingInfoForSM Arg in addition to the already existing response (IPSMGW-730). This also involved corresponding updates to the Store Routing Info Cassandra and Fetch Routing Info Cassandra features.

Fixed attempted double-send of MtForwardSMError triggered in MtForwardSMRequest error handling logic (IPSMGW-709).

Improved behavioural consistency between CS Delivery and PS Delivery features (IPSMGW-671).

Both the CS Delivery and PS Delivery use fallback avoidance codes in their configuration. Refer to their respective configuration and behaviour sections for further details (IPSMGW-666)

The MSISDN is now made available in in Session State by the new Determine MSISDN feature (IPSMGW-670).

All features that initiate MAP requests towards the HLR can address the request based on a GT address formed from the subscriber’s MSISDN. This is configured in the Shared Configuration Profile.

Ensured correct RP Message Reference generation during simultaneous SMS delivery to a single IMSI in the Generate Message Reference feature (IPSMGW-719). This uses atomic Compare and Set with configuration regarding number of Compare and Set retries and back-off between retries.

Update the MAP proxy and ATM registration features to optionally address the HLR leg using a GT address formed from the inbound subscriber MSISDN. Controlled using an introduced useMsisdnAsHlrAddress option. (IPSMGW-654, IPSMGW-661)

The SMMA callflow now handles error responses to the SendRoutingInfoForSM request with appropriate responses instead of always responding with NETWORK_OUT_OF_ORDER (IPSMGW-633)

CDRs are now handled solely by features instead of the previously existing mappers. Several new features are available for this: CDRInfo, DiameterV8d0ServiceInfo, IpsmgwLegacyCdr and IpsmgwAvpCdr. The CDRInfo and DiameterV8d0ServiceInfo features populate session state with information consumed by the IpsmgwLegacyCdr feature (to write old 2.4.0 format CDRs) or by the IpsmgwAvpCdr feature (to write new 2.5.0 format AVP CDRs).

Added SM-Delivery-Not-Intended configuration for FetchImsi feature (IPSMGW-619).

Improved SRI error handling (IPSMGW-633).

Fixed potential for incorrect origination address in outbound HLR dialogs (IPSMGW-655).

Added module packs for CDR features.

SM Delivery Reports received from the UE in response to MT SMS-over-IP messages are now used to determine if delivery was successful.

The fallback mode for MT traffic is configurable, allowing PS-to-CS fallback, CS-to-PS fallback, or PS and CS only modes. For details please refer to MT Delivery Flows.

SIP Messages containing an RP-SMMA body are now supported, and will trigger a ReadyForSM notification to the HLR For details please refer to Short Message Memory Available Flows.
