IMAP Idle
A part of the IMAP mail protocol. This provides a mechanism for push email over IMAP by allowing a constant IMAP connection to be maintained between the email server and the email client.
IMEI
International Mobile Equipment Identity. Each GSM mobile phone has a unique IMEI. It is used to identify the mobile phone (not the GSM subscriber using the phone). A definition of the IMEI can be found at the UMTSlink web site.
IMSI
International Mobile Subscriber Identity. A number uniquely identifying a GSM subscriber. The number contains two parts. The first part identifies the GSM network operator with whom the subscriber has an account. The second part of the number is allocated by the network operator to identify uniquely the subscriber. IMSI = MCC + MNC + MSIN (HLR + SN).
J2EE
Java 2 Platform Enterprise Edition. J2EE is a platform-independent, Java-centric environment from Sun for developing, building, and deploying web-based enterprise applications online. The J2EE platform consists of a set of services, APIs, and protocols that provide the functionality for developing multi-tiered, web-based applications.
JNDI
Java Naming and Directory Interface (JNDI). A part of the Java platform providing applications based on Java technology with a unified interface to multiple naming and directory services, such as LDAP.
JSF
Java Server Faces. A user interface framework designed to aid in building Java-based web applications. These applications will run on the server side of the process and will render the user interface side back to the client.
JSP
Java Server Pages. A scripting language based on Java for developing dynamic web pages and sites. It is typically used on Solaris and Linux platforms.
LDAP
Lightweight Directory Access Protocol. A set of protocols for accessing information directories. LDAP is based on the standards contained within the X.500 standard, but is significantly simpler.
MCC
Mobile Country Code. A number identifying a country with a GSM mobile network. A list of MCC and MNC codes can be found at the UMTSlink web site.
MD5
A one-way hash algorithm used to create a message digest for digital signatures. MD5 is used with 32-bit machines and can be used when large messages have to be compressed in a secure format before a private key is used.
MMS
Multimedia Message Service. A store-and-forward method of transmitting graphics, video clips, sound files, and short text messages over wireless networks using the WAP protocol. Carriers deploy special servers, dubbed MMS Centers (MMSCs) to implement the offerings on their systems. MMS also supports email addressing, so the device can send emails directly to an email address. The most common use of MMS is for communication between mobile phones.
MNC
Mobile Network Code. A number identifying a mobile network operator in a specific mobile country. The combination of MMC and MNC provides a unique identifier for every GSM mobile network operator worldwide.
MSIN
Mobile Subscriber Identification Number
OMA
Open Mobile Alliance. Standardization organization focused on definition of industry standards for the mobile industry.
OSS
Operational Support System - a generic term for a suite of programs that enable an enterprise to monitor, analyze and manage a network system.
OSS/J
The OSS through Java Initiative produces a standard set of Java technology based APIs to jump-start the implementation of end-to-end services on next-generation wireless networks and leverage the convergence of telecommunication and internet-based solutions.
RAM
Random Access Memory
RDBMS
Relational Database Management System. Organizes data into related rows and columns as specified by the relational model. Microsoft SQL Server and Oracle are examples of relational database management systems. A Microsoft Access database is an example of a relational database.
SMS

SMTP
Simple Mail Transport Protocol. The main internet protocol used to send email.
SN
Subscriber Number
SOAP

SOAP messages are independent of any operating system or protocol and may be transported using a variety of internet protocols.
SQL
Structured Query Language. A standardized query language for requesting information from a database.
SSL
Secure Sockets Layer. A protocol that transmits a user's communications over the internet in an encrypted form. SSL ensures that the information is sent unchanged to the server the user intended to send it to. Online shopping sites frequently use SSL technology to safeguard credit card information.
