Terms and definitions in messaging

Multichannel messaging service is based on a variety of telecommunication and Internet technologies. In the description of services, we often use abbreviations that may not always be known to you. Here we have compiled a glossary of terms and definitions used in the industry.

Hub

An SMS Hub usually implies P2P messaging, and is used by Mobile Operators to send message to operators they do not have reach to via SS7. The advantage of using a hub is it reduces the number of commercial agreements a mobile operator needs to maintain, but it is not the highest quality route since the Hub is another Hop in the delivery chain and may not report back actual Delivery Notifications. Sending A2P messages via a SMS Hub is usually frowned upon and not permitted by most mobile operators.
