¿µ¹®³»¿ë¿ä¾à This document focuses on defining independent or integrated service areas for each PLMN ID to ensure seamless content delivery during handovers. Additionally, it addresses efficient resource allocation between eMBMS and Unicast services, with priority adjustments based on operational needs, such as disaster response or normal operations. The document also establishes system interconnections between the controlling network (Public network A) and the resource-sharing network (Public network B), including interface definitions, parameter settings, and IP tunneling mechanisms. Furthermore, it emphasizes QoS management by ensuring guaranteed bit rates (GBR) for eMBMS services using QCI 2, tailored to the latency-sensitive and fixed-bandwidth requirements of multimedia broadcasts. Overall, the document provides a comprehensive framework for implementing eMBMS services in a shared RAN environment, addressing technical challenges such as resource allocation, service continuity, and interoperability across diverse public safety networks.
