			<text>

				a technique used in charging;

				for pre-paid subscribers the standard way to charge services is online

				– subscriber's balance is checked in the billing system and if sufficient, the service (e.g. sending a SMS) is provided, otherwise the service is denied;

				if the billing system is not currently available (so we can't say if the subscriber's balance is high enough), we can provide the service anyway and try to charge it later;

				this feature requires saving state (transactions which weren't charged yet) in some persitent storage (CDR files, SQL database etc.)

				and can be done at the billing gateway or directly at system like SMSC

		<explanation language="en">

			<text>

				a kind of electronic communication between two persons or a group chat;

				compared to e-mail, IM messages are short (few words, sentence) and the other side is expected (depending on his/her online status) to read and respond it immediately;

				compared to SMS, IM messages are cheap – typically free of charge;

				important IM feature is presence – the sender knows current status of the recipient: online, offline, away, busy etc.;

				IM is rooted in the computer world but nowadays it is often used also on mobile phones as an alternative to (expensive) SMS – in such case it is called OTT and requires mobile Internet connectivity;

				IM messages are usually transferred over an TCP/IP protocol – good example is Jabber/XMPP which is free and open protocol for IM and presence based on XML

				filters are executed on the server where MDA resides,

				so they are independent of the MUA currently used by the user
