3 Feature Descriptions
This chapter describes the features for the 9.2.0.0.0 release.
3.1 Release 9.2.0.0.0
This chapter introduces the new features or feature enhancements for DSR, vSTP, and VNFM.
3.1.1 DSR Features
The following DSR features are implemented in release 9.2.0.0.0:
- Diameter End-To-End Security: The Diameter protocol plays a crucial role in modern telecommunications networks for Authentication, Authorization, and Accounting (AAA) functions. To enhance the security of Diameter messages, oracle introduces Diameter End-to-End Security (DESS) feature, allowing the signing and verification of messages exchanged between network nodes. For more information, see Oracle Communications Diameter Security Application User Guide with UDR.
- Enhanced Address Resolution: Enhanced Address Resolution is an advanced networking protocol designed to improve the efficiency and reliability of address resolution processes in modern networks. For more information, see Oracle Communications Diameter Signaling Router Range Based Address Resolution User Guide.
- DSR Routing list changes: Routing rules and rule actions are used to implement the routing behavior required by the operator. Routing rules are defined using combinations of the following data elements Destination-Realm, Destination-Host, Origin-Host, and Origin-Realm. For more information, see Oracle Communications Diameter Signaling Router Feature Guide.
- LDAP Authentication: This enhancement allows operators to connect to their centralized user management systems for SSH users through LDAP, there by avoiding the need to create explicit users on DSR and simplifying the operations at customer. For more information, see Oracle Communications Diameter Signaling Router Operations, Administration, and Maintenance Guide.
- DSR Traffic Throttle Points and Groups Table Size Increase: The capacity for traffic management is enhanced by increasing the maximum number of Traffic Throttle Points and Traffic Throttle Groups per network element from 500 to 1500, and raising the maximum number of Shared Traffic Throttle Groups that can be marked as shared under the control of a single NOAM from 1000 to 3000. For more information, see Oracle Communications Diameter Signaling Router Diameter User Guide.
3.1.2 vSTP Features
The following vSTP features are implemented in release 9.2.0.0.0:
- Cluster Routing Support: The Cluster Routing feature eliminates the need for a FPC (Full Point Code) entry in the routing table to route to every signaling point in every network. The Cluster Routing feature allows the vSTP to configure one routeset to a entire cluster of destinations. This feature also allows the vSTP to manage and switch traffic to more end nodes. For more information, see Oracle Communications Diameter Signaling Router Virtual Signaling Transfer Point User Guide.
- Nested Cluster Routing: The Nested Cluster Routing feature provides a mechanism that allows both cluster and member routes to be provisioned in the same cluster. For more information, see Oracle Communications Diameter Signaling Router Virtual Signaling Transfer Point User Guide.
- Network Routing : Network Routing allows the user to provision a single routeset which can be used for all MSUs destined to members of that specific network. For more information, see Oracle Communications Diameter Signaling Router Virtual Signaling Transfer Point User Guide.
- Calling Name Conversion Facility (CNCF) : The CNCF (Calling Name Conversion Feature) simplifies the way calling name information is delivered in telecommunications. It converts ISUP IAM messages (used in traditional telephony) between using a proprietary PIP (Party Information Parameter) and standard GN (Generic Name Parameter). For more information, see Oracle Communications Diameter Signaling Router Virtual Signaling Transfer Point User Guide.
- Support for Applying GTT Action from intermediate GTT Sets : The Intermediate GTT Action Application feature enhances the flexibility of Global Title Translation (GTT) actions in your network. Previously, certain actions were restricted to the last GTT set only. With this feature, user can apply GTT actions from intermediate GTT sets for all actions. For more information, see Oracle Communications Diameter Signaling Router Virtual Signaling Transfer Point SS7 Security Guide.
- SFAPP ATIGTT Set : The SFAPP ATIGttset feature is designed to optimize the routing of ATI (Any Time Interrogation) messages in the network. When enabled, it ensures that ATI messages are directly routed to their corresponding destinations without the need for a selector lookup. This feature is useful only when the GTT Action (Global Title Translation Action) is set to SFAPP (Specific Forwarding Application). For more information, see Oracle Communications Diameter Signaling Router Virtual Signaling Transfer Point SS7 Security Guide.
- G-Port SRI Query for Prepaid: The G-Port SRI Prepaid Feature enhances standard G-Port functionality by ensuring that all Send Routing Information (SRI) queries from the Prepaid Service Control Point (SCP) receive a direct response with portability routing information. This feature simplifies tariff determination and routing for prepaid subscribers, whether they are ported or not, by providing a meaningful G-Port response for every query. For more information, see Oracle Communications Diameter Signaling Router Mobile Number Portability User Guide.
- Gateway Screening Enhancement: vSTP now supports screening of SCMG (SCCP Management) messages on the basis of scmg message type, affected Point code and affected SSN (subsystem number) by configuring required MTP Screening rule and Screen Groups. For more information, see Oracle Communications Diameter Signaling Router Virtual Signaling Transfer Point User Guide and Oracle Communications Diameter Signaling Router Virtual Signaling Transfer Point SS7 Security Guide.
- Group Code is extended to ITU-International Linksets: The Group Code concept, traditionally applied within national signaling networks, can be extended to ITU–International Linksets to provide a structured and efficient method for managing international signaling connections. This feature will allow vSTP to route traffic for two or more destinations or countries that may have overlapping point code values. For more information, see Oracle Communications Diameter Signaling Router Virtual Signaling Transfer Point User Guide.
- vSTP Measurement Reports must contain only the servers or links being used: The measurement (indexed by link or connection) must be pegged only on the MP server hosting that link or connection. Previously, measurement reports showed pegging of measurements on other servers, in addition to the MP server hosting the link or connection. For more information, see Oracle Communications Diameter Signaling Router Measurement Reference Guide
3.1.3 VNFM Features
The following VNFM features and enhancements are implemented in release 9.2.0.0.0:
- MTU Support in Scale: MTU Support in Scale allows users to specify Maximum Transmission Unit (MTU) values for all networks within additional parameters in (V1) or within configurable properties in (V2). if an MTU value is provided for the Signaling network, MTU values must also be provided for all other networks. For more information, see Oracle Communications Virtual Network Functions Manager Installation and User Guide.
- MTU Support for Signaling : MTU Support in Scale allows users to specify Maximum Transmission Unit (MTU) values for all networks within additional parameters in (V1) or within configurable properties in (V2). If an MTU value is provided for the Signaling network, MTU values must also be provided for all other networks. For more information, see Oracle Communications Virtual Network Functions Manager Installation and User Guide.
- MTU Support for NOAM: MTU Support in Scale allows users to specify Maximum Transmission Unit (MTU) values for all networks within additional parameters in (V1) or within configurable properties in (V2). If MTU is provided for NOAM, both xmiNetwork and imiNetwork values must be included. For more information, see Oracle Communications Virtual Network Functions Manager Installation and User Guide.
- MTU Support for DR NOAM : MTU Support in Scale allows users to specify Maximum Transmission Unit (MTU) values for all networks within additional parameters in (V1) or within configurable properties in (V2). if MTU is provided for DR NOAM, both xmiNetwork and imiNetwork values must be included. For more information, see Oracle Communications Virtual Network Functions Manager Installation and User Guide.
- Multiple NTP Server Ip support in DSR and SDS VNFs : VNFM supports multiple NTP server IP addresses, which can be specified during the instantiation of DSR and SDS VNFs. This supports both IPv4 and IPv6 NTP server IP addresses. For more information, see Oracle Communications Virtual Network Functions Manager Installation and User Guide.
