P2P
Person-to-person SMS is traffic one person sends another. It has no sender registration or template approval, so it is not for application messages.
Definitions only — a term explained here is not a service we sell.
Person-to-person (P2P) messaging is traffic that starts on one person's handset and ends on another person's handset. It has no application bind, no sender registration and no template approval.
The difference from A2P is commercial and regulatory as much as technical: A2P runs under a commercial agreement and, in many markets, a registered sender, while P2P has neither. What is A2P SMS sets out the registered route that P2P lacks. Both use the same store-and-forward core.
Where a P2P message goes
- Application
- SMPP gateway
- SMSC
- HLR / HSS
- MSC / MME
- Handset
- Delivery receipt
Text description
The figure shows the application path: application to SMPP gateway, SMSC, HLR/HSS, MSC/MME, handset and delivery receipt. On a P2P message the sender's handset submits to the SMSC of its own network, which stores the message and forwards it to the recipient's network. No application or registered sender sits on the path.
