OCECAS refers to Oracle Communications Evolved Communications Application Server in the following entries.
The 3rd Generation Partnership Project is a group of telecommunications organizations that cooperates on standards development to provide a reliable environment in which to define their technologies. These technologies include network technologies for cellular telecommunications and encompass radio access, the core transport network, and service capabilities.
An action block that is embodied by an icon that can be dragged and dropped in a control flow. Each activity performs a particular task in a control flow and has one input and a number of outputs, except for the Start and End activities, which have one output and one input respectively.
A stored message that is played to one of the parties in a voice call session. A sample announcement might be something such as: ”The number you have called is no longer in service.”
back to back user agent (B2BUA)
A back-to-back user agent (B2BUA) acts both as a user-agent client and a user-agent server in SIP call processing. It maintains the complete call state and participates in all call requests that are sent on dialogs that it has established. OCECAS acts as a back-to-back user agent when it needs to detect changes, or monitor the progress of an on-going call.
The process of managing and deploying change sets across testing, staging, and production environments in OCECAS.
A set of changes to a session or service that is grouped as a single deployable bundle in the OCECAS change management system. A change set can consist of both control flow and configuration changes.
The function that generates event detail records (EDRs) for offline charging.
The application server feature that triggers a charging event to either the charging data function for offline charging, or the online charging system.
A network that employs legacy Signalling System 7 (SS7) protocols such as CAMEL, which are used by 3G networks.
A logical, flowchart-like structure that consists of linked activities and decisions that specify the management and processing of a voice call or multimedia session. A control flow is created through the OCECAS Session Design Center.
The software-based signalling components of the IP Multimedia System (IMS) core.
The Diameter protocol evolved from the RADIUS protocol and is considered the next generation authentication, authorization, and accounting protocol.
A set of related WebLogic server resources that you manage as a unit. A domain includes an administration server and can include additional managed servers. You use the administration server to configure and manage all resources in the domain. You can define multiple domains based on application requirements, geographic locations and so on. Or you can use a single domain to centralize all WebLogic Server administration activities.
A written record of actions taken by OCEAS; for example, when an activity is processed in a control flow. The format and content of each event detail record is based on the particular action that generated it and any associated data.
IP multimedia subsystem (IMS) is a standardized framework, originally designed by the 3rd Generation Partnership Project for delivering multimedia content (voice, video, etc) over IP packet switched networks.
JavaScript Objejct Notation (JSON) is a text-based data-interchange format that is programming-language independent and is easy for humans to read and write.
The combination of country and language that identifies the originating or terminating location in a voice call or multimedia session.
Network Functions Virtualization (NFV)
A network architecture that virtualizes network node functions to create communication services from discrete building blocks. A virtualized network function allows you to perform a network function in place of a custom hardware appliance.
Stands for not only SQL. Its principal characteristic is its non-conformance to the relational database model. It is a database management and design model that is intended to scale and perform better for very large data storage applications.
Oracle Universal installer (OUI)
Oracle Universal Installer is a Java-based installer application that enables you to install Oracle applications and components using a graphical user interface.
An acronym for representational state transfer, it is a style of network architecture that imposes a set of constraints on components, connections and data in the provision of services in a distributed hypermedia network system. The World Wide Web, for example, is said to represent the REST architectural style. For more information, see the W3C REST web page.
An API used in web services that conform to the REST architectural constraints. Typically, RESTful APIs use JSON or XML for data interchange and standard HTTP methods such as GET, PUT, POST, and DELETE.
Service Centralization and Continuity Application Server (SCCAS)
Provides anchoring of calls in the IMS home network as part of SRVCC.
An organization that uses OCECAS to provide voice call and multimedia session-processing services to its customers.
A device that interacts with OCECAS in Voice over Internet Protocol (VoIP) networks in setting up, processing, and tearing down secure, SIP-based interactive communication sessions.
A service in a telecommunications system that sends short messages of up to 160 characters in length, commonly known as text messages. Messages are typically exchanged between mobile devices.
Single Radio Voice Call Continuity (SRVCC)
Provides for the transfer of a call from a circuit switched network to a packet switched network.
The Session Initiation Protocol (SIP) works with other protocols in the creation and management of real-time multimedia communication sessions between Internet endpoints such as mobile devices. For a complete description, see SIP: Session Initiation Protocol by the Internet Engineering Task Force (ietf).
A set of services that support a VoLTE network by delivering the telephony services that subscribers expect.
A user database repository (UDR) consists of subscriber data, including information about services to which the subscriber has subscribed. The data can reside in multiple data sources that are accessed and presented through a defined view.
A service built and delivered to add additional value to an end subscribers experience.
Voice over Internet Protocol (VoIP) provides voice and multimedia sessions over IP networks rather than the public switched telephone network (PSTN).
Voice over Long Term Evolution provides voice and video calls over an LTE system, which was originally regarded as IP system for carrying data. VoLTE uses IMS to be part of a rich media solution. VoLTE is defined by the GSM Association (GSMA). For more information, see VoLTE Service Description and Implementation Guidelines by GSMA.
VoWiFi provides Wi-Fi based voice over IP service for devices such as personal digital assistants (PDAs) and laptops.
