For more information, see XER.


Customized Applications for Mobile Networks Enhanced Logic. CAMEL is an ETSI standard that defines a set of standards designed to work on either a GSM core network or a UMTS network. CAMEL provides various mechanisms to support operators' services that are not covered by standard GSM services, even when roaming outside the HPLMN (Home Public Land Mobile Network).

High Availability. HA is a system design protocol and associated implementation that ensures a certain degree of operational continuity during a given measurement period.


Home Subscriber Server. In the IMS architecture, HSS contains subscription-related information, performs authentication and authorization of the user, and can provide information about a subscriber's location and IP information.


Initial Filter Criteria. In the IMS architecture, the iFC is an XML-based format used for describing an orchestration logic.


IP Multimedia Subsystem. The IMS is an architectural framework for delivering multimedia services over the Internet Protocol (IP).

For more information, see IP.


Intelligent Network. The IN architecture enables operators of both fixed and mobile networks to provide advanced services, including prepaid calling, toll free calls, and voice mail.


Intelligent Network Application Part. INAP is a signaling protocol in the IN architecture.

Intelligent Peripheral

In the IN architecture, an Intelligent Peripheral is responsible for playing announcements to, and collecting information from callers, as required by the service logic, and as directed by the service control point.


Internet Protocol. IP is used for communicating data across a packet switched internet using TCP/IP.


Interface between the CSCF and Service Broker or between Service Broker and AS.


Java Database Connectivity. JDBC provides database-independent methods for querying and updating data in a database.


Java Management Extensions. JMX provides tools for managing and monitoring applications, system objects, devices, and service oriented networks.

For more information, see MBean.


MTP Level 3 User Adaptation Layer. M3UA enables the SS7 protocol User Parts to run over IP instead of telephony equipment, such as ISDN and PSTN.

For more information, see SS7.


Mobile Application Part. MAP is an SS7 protocol that provides an application layer for various nodes in GSM and UMTS mobile core networks and GPRS core networks. The MAP enables these networks to communicate with each other and provide services to mobile phone users.

For more information, see SS7.


Managed Bean. An MBean represents a resource that must be managed and runs in the Java virtual machine. Mbeans can be used for getting and setting application configuration, collecting statistics, and notifying events.

For more information, see JMX.


Media Resource Function. In the IMS architecture, the MRF provides media-related functions, such as media manipulation and playing tones and announcements.


Mobile Switching Center. An MSC connects the landline public switched telephone network (PSTN) system to the wireless communication system. An MSC is typically split into:

An MSC incorporates the bearer-independent call control (BICC).


Message Transfer Part. The MTP is a part of the SS7. MTP provides reliable, unduplicated, and in-sequence transport of SS7 messages between communication partners.


Next Generation Network. An NGN describes key architectural evolutions in telecommunication core and access networks that will be deployed over the next five to ten years.


Point Code. In SS7 architecture, a PC acts like an IP address in an IP network. A PC is a unique address for a signaling point. A PC is used in MTP layer 3 to identify the destination of a message signal unit (MSU).


Pulse Code Modulation. PCM is a digital representation of an analog signal. In this representation, signal magnitude is sampled regularly at uniform intervals and then quantized to a series of symbols in a binary code.


Public Land Mobile Network.


Public Switched Telephone Network.


Service Broker. SB is a network element that efficiently manages service interaction and composition. SB resides between the service layer and the converging network. An SB is traditionally decoupled from the core switch and the service execution or service creation environment.


Service Capability Interaction Manager. The SCIM orchestrates service delivery among application server platforms within the IP Multimedia Subsystem (IMS) architecture.


Service Control Point. An SCP is a component of an intelligent network telephone system that is used to control the service. An SCP queries the service data point (SDP) that holds the database and directory. Then the SCP identifies the geographical number to which the call is to be routed based in information SDP database.

The SSP implements the Basic Call State Machine (BCSM) which is a Finite state machine that represents an abstract view of a call from beginning to end. As each state is traversed, the switch may invoke a query to the SCP to wait for further instructions on how to proceed.

For more information, see SCP.


Signal Transfer Point. An STP is a router that relays SS7 messages between signaling end-points (SEPs) and other signaling transfer points (STPs).

For more information, see SS7.
