Emsg Architecture
Version 8.1.0 May 2023	< [contents] >
Sending & Receiving Text Messages Emsg aims to make the complexity of computer systems and connectivity with the mobile networks quite transparent to the user. As far as the user is concerned, message submission is as simple as sending an email or creating a message using the web application. In just a few clicks the message is on it's way to the intended recipient, or if Emsg is integrated into business processes, the message might be generated automatically in the background without any user intervention at all. Once created, the message is transported to the Emsg server over the network using SMTP or HTTP and delivered to the message queue in an smtp format text file. Emsg's inbound process extracts the sender, receiver and message details, applies acceptance/rejection rules and stores in the database ready to send. The outbound server process picks up messages from the database queue and initiates communications sessions with each target network to send all waiting messages to the mobile operator's Short Message Service Center (SMSC), which usually responds with a message success status. Normally, it is only a matter of seconds for the message to arrive on the handset, however delays may occur if a network is heavily congested. The recipient reads the message and, if appropriate, sends a reply which will arrive back on the Emsg in similar time, be processed by the inbound server and logged against the original message.

Emsg Architecture
Version 8.1.0 May 2023	< [contents] >
Requesting & Receiving information by Text Message Mobile users can initiate the sending and receiving of messages from an Emsg Server. A mobile handset may initiate a request to the Emsg Server by creating and sending a "keyword" text over the mobile network to one or more numbers or shortcodes allocated to an Emsg Server. The server validates the keyword request, retrieves information matching the request from the database and returns the information in a text to the mobile originator. A mobile handset may also simply create and send messages to an Emsg Server to be updated and stored in the database.. In summary, Emsg is built robust and effective, ideal for use in high volume, high priority messaging environments such as hospitals, emergency services and university campuses. In the corporate sector, Emsg delivers reliable and timely information such as stock levels, currency rates and computer system alerts to staff and customers wherever they are. Key Features Delivery usually less than a minute Replies logged against original message Sender emailed message status and replies if desired Hundreds of recipients may be inclued in a single submission Users only need to know how to use everyday tools such as email or browser No need for users to have in depth understanding of network complexity Standard reply to numbers and shortcodes supported Full message id and message status tracking

Emsg Server
Version 8.1.0 May 2023	< [contents] >
The Emsg Server process continuously polls inbound queues for new messages, which are then validated and added to the database and outbound message queue ready for sending depending on the status of the sender and receiver. All requests and replies are handled by the server process, which performs the keyword lookups for the information in the database or matches replies with the original message sent and generates a return email if configured to do so. The Graphic Use Interface (GUI) shown above gives administrators visibility into the realtime operation of the server process itself. In the background, comprehensive message status and communications logging is being performed with viewing of logs available through the Emsg Control Center. Key Features Long messages split into multiple segments Built-in and configurable rules for acceptance and rejection of senders/receivers Anti-spam validation to eliminate unnecessary sending of unwanted messages Rosters to ensure the right people get sent the right message at the right time Multiple instances of outbound server can be run to increase throughput Separate instance of inbound server can be run to increase throughput Excellent reliability and small memory footprint

Emsg Web Application
Version 8.1.0 May 2023	< [contents] >
The Emsg Web Application gives users and administrators online access, from anywhere on an Intranet or the Internet, to day to day activities such as message sending, review of message logs, and maintenance of staff (recipient) directories, standard messages, rosters and groups. The Emsg web is easy, fast and effective to use, requiring no software to be loaded on a user's workstation and is available in a full featured version for desktops or a smaller, "cut-down" version for mobile devices such as the 3G handsets and PDA devices (see graphic above). Of course, some users like to use the mobile version on their desktop computer. The web application requires the user to login to the system using their ID and password, which is validated against the Emsg database. Users can be allocated different levels of authority to control whether they are able to maintain staff directories or view messages sent by other users. Key Features Login ID and password challenge User authority levels; Administrator, Security and Standard User Individual, multiple and group selection of recipients Visual keys to successful, failed and reply messages in log "Canned Messages" selectable at send time to cut down typing Search facilities by group, name, location and job position Easily modifiable "classic" .ASP web page construction
