name: PTP
full_form: Point-to-Point
context: This example shows a UE receiving MBMS service over a PTP bearer in the SRNC moving into DRNC area where the service is available over a PTM bearer. Figure 48: MBMS User mobility from PTP to PTM cell 1. MBMS Service has been activated and is currently ongoing. UE is receiving the MBMS traffic using a PTP bearer. SRNC makes the decision that to add a cell in the DNRC to the active set. The Cell already has PTM bearer for the MBMS service. 2. UE Linking is performed via using RNSAP Radio Link Setup Request message to add the radio link in the new cell. Parameters: MBMS Bearer Service List, 3. MBMS service context in the DRNC is updated. 4. DRNC responds with RNSAP RL set up response message. Parameters: Active MBMS Bearer Service List 5. NBAP RL Set up procedure to set up the RL on the NodeB 6. RRC Active Set Update to the UE to add the PTP radio link on the new cell to the active set. 7. When the cell in the DRNC is good enough to provide MBMS service to UE, the SRNC deletes the PTP
description: A Point-to-Point (PTP) bearer is used for transmitting Multimedia Broadcast Multicast Service (MBMS) traffic from a single point to another. It's utilized by the User Equipment (UE) to receive MBMS service in the Serving Radio Network Controller (SRNC) area before transitioning to a Point-to-Multipoint (PTM) bearer when moving into the Drift Radio Network Controller (DRNC) area.
explanation: The text explicitly refers to 'PTP bearer' as a mechanism for transmitting MBMS traffic, aligning with the definition of a bearer in telecommunications. Bearers establish and manage connections for data transmission.
