In LTE (Long-Term Evolution) and mobile communications in general, Mo stands for Mobile Originating.
Understanding Mobile Originating (MO)
Mobile Originating refers to any communication, data transmission, or action that is initiated by the mobile device (User Equipment or UE). It signifies that the message, call, or data flow is starting from the user's handset or cellphone.
According to the provided reference:
Mobile Originating refers to a message being sent from a mobile handset. The message is ORIGINATED at the mobile/cellphone end.
This means when your phone sends data to the network or another party, it's performing a Mobile Originating action.
MO vs. MT
To fully understand MO, it's helpful to contrast it with its counterpart: Mobile Terminating (MT).
- Mobile Originating (MO): Communication starts from the mobile device.
- Mobile Terminating (MT): Communication is being sent to the mobile device.
The reference also clarifies this:
Mobile Terminating (MT) refers to a message being sent to a mobile handset.
Think of it like a conversation:
- MO: You speaking (initiating the sound from your mouth).
- MT: Someone else speaking to you (sound terminating at your ears).
| Feature | Mobile Originating (MO) | Mobile Terminating (MT) |
|---|---|---|
| Initiator | Mobile Device (Handset/UE) | Network or another party |
| Direction | From Mobile Device -> To Network | From Network -> To Mobile Device |
| Action | Sending, Uploading, Initiating | Receiving, Downloading |
Practical Examples of Mobile Originating Actions in LTE
Many everyday actions on your smartphone involve Mobile Originating processes. Some common examples include:

- Uploading a photo or video: Sending data from your gallery to a social media platform or cloud service.
