1. A service data transmission method, comprising:
a terminal device receiving a multimedia broadcast multicast service (MBMS) service data of a first cell and an MBMS service data of a second cell before a cell change; and
the terminal device stopping receiving the MBMS service data of the first cell after the cell change;
wherein the first cell is a cell before the cell change, and the second cell is a cell after the cell change,
wherein the method further comprises:
the terminal device receiving a first MBMS service data and a second MBMS service data of the first cell, wherein the second MBMS service data is same as the first MBMS service data, and a transmission start time of the second MBMS service data is later than a transmission start time of the first MBMS service data; and
the terminal device receiving and processing the first MBMS service data, and when the terminal device detects that the first MBMS service data fails to be received, the terminal device receives and processes the second MBMS service data.
