2 Terms
2.1 A-E
| Access Point (AP) | A device that allows Wi-Fi capable devices to connect to a wired network using Wi-Fi technology. | |
| Action | An executable operation triggered by setting attributes on an MO. Each action is defined in the related MOC description. | |
| Active node | SAPC node that is processing traffic and provisioning operations. | |
| Alarm |
Raised by the system to indicate an unexpected
behavior of malfunction requiring corrective action by the user. An
alarm has at least states raised (initial detection of the fault)
or cleared (when the fault no longer exists). An alarm can also change
state regarding perceived severity. Alarms are also called "stateful" alarms to emphasize that they have a state. An active
alarm is an alarm that has been raised but not cleared. All alarm state changes including cleared state are recorded in the Alarm Log. Each alarm has an alarm Operating Instructions document. It describes the possible fault reasons, fault locations, and the potential service impact. It also describes the procedure to execute to eliminate the problem and eventually clear the alarm. | |
| Alert | A stateless alarm, that is, an alarm that can only have the raised state. As an alarm, an alert has an associated Operating Instructions document and is reported in real time as an SNMP notification. Alerts are recorded in the Alert Log but are not exposed in any list over the NBI. | |
| Alias Role | Identity of a role, which has meaning to the user. An alias role is an alias for one or more real roles. The definition of alias role allows the user to use names of roles that the user is used to. Also, the same alias can be used for several real roles. The latter can be useful when different types of MEs have defined real roles with different names, but which requires the same (or similar) authority. | |
| Application | A service enabler deployed by service providers, manufacturers, or users. Individual applications are often enablers for a wide range of services. | |
| Application detection filter | A logic used to detect packets generated by an application based on extended inspection of these packets, such as header and/or payload information, and dynamics of packet flows. The logic is entirely internal to a PCEF enhanced with ADC. | |
| Application Function (AF) | A logical element that enables applications to control IP-CAN bearer resources. The AF shall use the Rx reference point to provide session information to the SAPC. In the context of this document, the AF can be the Proxy Call Session Control Function (P-CSCF), a DPI node (such as SASN), or a third-party service provider. | |
| Application identifier | An identifier, referring to a specific application detection filter. | |
| Asynchronous replication | The data is committed in the active node and then it is replicated to the mated peer. Therefore, the standby node lags behind the active until the data is replicated. | |
| Attribute | Represents the configuration. The read-only attributes in the MOs describe configuration state and operational values. The writable attributes control the operation and configuration for the particular network resource. Each attribute is defined in the related MOC description. | |
| Authentication | The process of verifying the identity of an entity. | |
| Authorization | The granting of permission based on authenticated identification. | |

| Data Model | A mapping of the contents of an Information Model into a form that is specific to a particular type of data store or repository. A data model is basically the rendering of an information model according to a specific set of mechanisms for representing, organizing, storing, and handling data. In contrast to an Information Model, a Data Model includes implementation (and protocol-) specific details. That is, rules that explain how to map MOs onto lower-level protocol constructs. | |
| Data Product/Data Plan | A Data Product or a Data Plan is a component of the operator Service Offering. It may be simple (for example, Mobile Data at Flat Rate Data Plan), but also complex (bundling different data services and assigning to each one specific usage condition, for example time, volume, or monetary). Data Products/Data Plans are configured in the SAPC using Subscriber Groups. | |
| Derived Data Type | Data type enhanced with extra restrictions and properties. Derived string data types contain, for example, length and content constraints. Derived integer data types contain extra range constraints. Each derived data type is defined in the related MOC description. | |
| Destination | It is either an end user or an external system that receives notification messages. | |
| Distinguished Name | The Distinguished Name (DN) is the name that uniquely identifies an entry in the directory. | |
| Directory Information Tree | Tree structure where a set of Lightweight Directory Access Protocol (LDAP) entries are hierarchically organized. | |
| DN | Distinguished Name. The name of an object tree that is shared between the system and the Management System. The DN is in 3GPP format (from root to leave). The DN is used to identify an MO uniquely in the system. It gives the path of the MO in the tree of objects. The system uses 3GPP formatted DNs where each relative DN part consists of the MOC name equal the MO identity. If the key attribute name is not equal to the MOC name plus ID, then the key attribute name is also appended to the MOC name separated by a dot. | |
| Dynamic PCC rules | Dynamic PCC rules are dynamically generated or modified by the SAPC based on information received from the AF and dynamically provisioned towards the PCEF. The PCC rule definition includes the 5-tuple filter along with charging and QoS Information. | |
| ECIM | Ericsson Common Information Model. Controls the MOM structure. The ECIM is based on the CIM standard. | |
| ECLI | Ericsson Command-Line Interface. A terminal-based Command-Line Interface that is used to monitor and manage the ME. The ECLI is based on industry de facto standard patterns. | |
| EF |

| Heartbeats | Used by a Management System to monitor the interface over which the alarms or alerts are to be sent. Heartbeats are needed because a management system cannot assume that a "silent" ME behaves properly. The Heartbeat event is reported as an SNMP notification at regular intervals. | |
| Information Model | An abstraction and representation of the entities (or MOs) in a managed environment, their properties, attributes, and operations, as well as the way that they relate to each other. It is independent of any specific repository, software use, protocol, or platform. | |
| IP-CAN bearer | IP transmission path of defined capacity, delay, bit error rate, and so on. | |
| IP-CAN session | Session identified by the IP address assigned to an UE attached to the Operator network. The UE can be reached using such IP address and the session lifetime should match with the period the UE is available through such IP address. | |
| IPoE | IP over Ethernet. IPoE encapsulation extends several LAN-based protocols, including DHCP, to allow use on a broadband network. | |
| IP Flow | A unidirectional flow of IP packets with the same source IP address and port number, the same destination IP address and port number, and the same transport protocol. Port numbers are only applicable if used by the transport protocol. | |

| MIB | Management Information Base. The collection of MOs, which control the configuration of an ME and its functionality. | |
| MIM | Management Information Model. A view of the MOM, where certain parts of the MOM can be hidden from the user, depending on the use case. The MOM is traditionally stored offline, while a MIM is traditionally stored online for use by tools. Often the MIM is represented in a different language to the MOM, for example, XML. There is normally one file, in whatever modeling format, per MIM. The cardinality between a MOM and a MIM is one to one. | |
| MO | Managed Object. A software object encapsulating the manageable characteristics and behavior of a particular hardware or software resource. An MO is an instance of a MOC. An MO normally has attributes providing information used to characterize the MOs belonging to the MOC. An MO can also have actions allowing the user to perform operations on the underlying implementation. | |

| Online Charging System | The entity that performs real-time credit control. Its functionality includes transaction handling, rating, online correlation, and management of subscriber accounts/balances. | |
| Operator Network Policies | Operator Network Policies are the different operator decisions that need to be added to the subscriber data stored in the operator nodes. They may not be visible in the contract between the service provider and the subscriber. Their purpose may be to comply with the operator strategy for network optimization, for up-sell, or with the existing regulation. They may result on more data assigned to the subscriber. The relation between the operator network policies and the Data Products can be any. | |
| Original Distinguished Name | It is the comma-separated list of the object Relative Distinguished Name (RDN) and its parents RDNs all the way up to the top of the object hierarchy, exactly as they were provisioned. | |
| Origin State Id | It is a monotonically increasing value that is advanced whenever a Diameter entity restarts with loss of previous state, for example upon reboot. It is used to allow rapid detection of Diameter terminated sessions. | |
| Overload Protection | Function that protects the system against load peaks. Prevents a processor or the system from crash at overload. Overload protection is needed to handle sudden load bursts even if there is an overload regulation. | |
| PCC deployment | Policy and Charging Control architecture that encompasses 3GPP accesses (E-UTRAN, UTRAN, GERAN), non-3GPP accesses, and fixed broadband access in the convergent scenario. In this deployment, the Ericsson Service-Aware Policy Controller (SAPC) interworks with the PCEF by Gx interface. | |

| Rule | It contains a condition formula that is evaluated to permit or deny the authorization to a resource or to return an output attribute. | |
| SDP | Software Delivery Package. An archive file (TAR file) with RPM® software packages and a file describing the Ericsson product data. A software item can be an SDP. A software item represents any kind of Ericsson software product that is present on the ME. | |
| SDN Domain | An SDN domain is a network domain that complies with the SDN architecture supporting one SDN Controller (SDN-C) and one or more Evolved Flow Switches (EFSs). The SDN domain can span multiple geographically separate sites. | |
| Seamless Handover | A method that ensures mobility of the user equipment in the network without affecting a call session, previously established. To secure continuity of the call connection during the handover, the “make before break” principle is applied. According to that principle, the UE attaches to new radio access point establishing a new connection. Once the traffic starts being conveyed through the new connection, the old one is released. | |
| Secured Operator SSID | Is a Service Set Identifier (SSID) that allows a user to connect to the Wi-Fi network using EAP method during Wi-Fi connection setup and grants access to Operator services and the internet. | |
| Service | It identifies a set of aggregated IP flows in the Enforcement function. The SAPC performs policy control over the services using PCC Rules. | |
| Service Chain | A service chain is a logical concept and an object type in the BBSC that determines a chain of service functions which a user’s data flow passes in a well-defined sequence. A service chain can replicate the data flow at specific points in the sequence and forward the replicas to specific service functions. | |
| Service Data Flow | An aggregate set of IP flows. If GPRS or WCDMA is used, it is possible that a service data flow is more granular than a PDP context. | |
| Service Data Flow Filter | A set of filter parameters used to identify one or more of the IP flows constituting a service data flow. At least the following means for the IP flow identification are supported: source and destination IP address+port, protocol. | |
| Service Function | A service function is a network node, or a cluster of network nodes, that analyzes or modifies individual user data packets or complete data flows. Some examples of service functions are deep packet inspection, Content Filter, and header enrichment devices. | |
| Services offering | The set of common Policy and Charging Control data offered by an operator to the end users, including, for example, allowed services, bandwidth limit, and Fair Usage data. Services offerings are managed in the SAPC by configuring subscriber groups. | |
| SF | System Functions. Common system functions and resources for the management entity such as Fault Management (Fm), Performance Management (Pm), and Security Management (SecM). SystemFunctions is one of the first-level branches in the MOM. | |

| Slice | The maximum allowed quota for a Reporting Group. | |
| SPID | Subscriber Profile ID. The Subscriber Profile ID for RAT/Frequency Selection Priority (SPID/RFSP) used to define camp priorities in Idle mode and to control inter-RAT/inter-frequency handover in Active mode. This index is mapped by the eNodeB (E-UTRAN), RNC (UTRAN), or BSC (GERAN) to locally defined configuration. For more information, refer to General Packet Radio Service (GPRS); Service Description; Stage 2, 3GPP TS 23.060 and General Packet Radio Service (GPRS) enhancements for Evolved Universal Terrestrial Radio Access Network (E-UTRAN) access, 3GPP TS 23.401. | |
| System Controller | There are always two System controllers (SCs) in the SAPC cluster. They provide the OAM and provisioning services. | |

| Struct | Handles structured attributes that can contain an arbitrary number of elements of the same or different type. Each struct is defined in the related MOC description. | |
| Subscription | The subscriber data stored in the operator nodes to guarantee fulfillment of the contract to a particular Service Offering, between the Service Provider (operator) and the subscriber. The part of the subscription stored in the SAPC consists of the set of Policy and Charging Control data that correspond to the contracted Service Offering, for example, allowed data services and bandwidth limit. | |
| SysM | System Management. Represents the system-level functions such as time handling and version handling. SysM is a system function. | |
| Tethering | A method of using a mobile device (such as a cell phone or smartphone) as a modem to connect another device (such as a laptop) to the Internet. The term gets its name from how a phone is attached to the computer using a USB cable, although wireless technologies such as Bluetooth can also be used. | |
| Transaction | Configuration changes are applied through atomic transactions. Thus, it is ensured that all or none of the operations are executed. | |
| Transparent VASs | Service functions that process the user traffic and add value. | |
| Transport Management | Transport-related functions and resources, for example, load sharing between all configured and available blades in the cluster, and distribution of incoming traffic to the system. Transport is one of the first-level branches in the MOM. | |
| Trap | An unacknowledged SNMP message carrying a notification or heartbeat. | |
2.5 U-Z
| Unknown session | A session that is not stored in SAPC. | |
| Untrusted Wi-Fi | A Wi-Fi access network that is not managed by the operator or does not provide sufficient security mechanisms. For example, a public open hotspot, a private Wi-Fi AP at home or any other Wi-Fi AP that does not fulfill security mechanism such as authentication and encryption. | |
| Upgrade | A product or product version that is created to provide an increased level of functionality or performance to a user. Upgrade is also the operation to replace a previous product or product version with a new product or product version that provides an increased level of functionality. | |
| Usage accumulator | The counter that accumulates the number of seconds or bytes that have been consumed by a subscriber or a group of subscribers sharing usage quota. | |
| Usage limit | The threshold of accumulated usage (volume or time) for a Reporting Group or a particular usage accumulator. | |
| Validity time | The maximum time period before a session reauthorization is required for fair usage control. | |
| Virtual IP | It is the regular method to connect a telecommunication node to an external Data Communication Network. Virtual IP (VIP) is the concept for collective addressing. With VIP, a shared IP address can be used to address distributed functions in a telecommunication node, which is a multi-processing cluster. | |
| XML Attribute | Attributes are used to specify additional information about the element. It may help to think of attributes as a means of specializing generic elements to fit your needs. An attribute for an element is displayed within the opening tag. The syntax for including an attribute in an element is: <element attributeName=value>. | |
| XML Element | Elements are used to classify data in an Extensible Markup Language (XML) document so that the data becomes "self-explanatory”. Opening (<element>) and closing tags (</element>) represent the start and end of an element. | |
