name: MBMS
full_form: Multimedia Broadcast Multicast Service
context: The block of bits, where , the number of bits transmitted on the physical broadcast channel, equals 1920 for normal cyclic prefix and 1728 for extended cyclic prefix, shall be scrambled with a cell-specific sequence prior to modulation, resulting in a block of scrambled bits according to where the scrambling sequence is given by clause 7.2. The scrambling sequence shall be initialised with in each radio frame fulfilling . For an MBMS-dedicated cell, the scrambling sequence shall be initialised with in each radio frame fulfilling .
description: The Multimedia Broadcast Multicast Service (MBMS) is a service defined by 3GPP for efficiently delivering multimedia content to multiple users over wireless networks. MBMS leverages the capabilities of cellular networks to broadcast and multicast data, reducing the load on the network infrastructure compared to traditional unicast methods. This service is particularly useful for applications such as mobile TV, live event broadcasting, and emergency alerts.
explanation: MBMS is classified as a Service because it refers to a specific telecommunications offering that utilizes cellular networks to deliver multimedia content in a broadcast or multicast manner, aligning with the context provided which discusses its technical implementation details.
