The present invention discloses a service data scrambling method, a service data descrambling method, an apparatus, and a system, and relates to the communications field. The service data scrambling method includes: receiving service data; using a service characteristic corresponding to the service data as a part of a scrambling parameter; generating a scrambling sequence according to the scrambling parameter; scrambling the service data according to the scrambling sequence; and sending the service data. According to the present invention, a service characteristic, an MBSFN area identity, a radio timeslot number, and the like are used as scrambling parameters to generate a scrambling sequence, and the service data is scrambled according to the generated scrambling sequence, thereby resolving a problem that relatively great interference is generated when multiple pieces of different service data are simultaneously transmitted in a same service area, and achieving an effect that interference between different service data sent simultaneously in the same service area can be reduced to a great extent. |
