摘要： A split architecture eMBMS with distributed BMSCs providing the same eMBMS service allows for a centralized key service where each BMSC is able to derive a set of MTKs from the MSK using the MTK-IDs as the differentiating input. This avoids the need to send MTKs to the BMSCs.
摘要翻译：具有提供相同eMBMS服务的分布式BMSC的分离架构eMBMS允许集中式密钥服务，其中每个BMSC能够使用MTK-ID作为区分输入从MSK导出一组MTK。这样可以避免将MTK发送给骨髓基质干细胞。
