METHODS PROVIDING MBMS SERVICE AND TRAFFIC KEY COORDINATION IN A MULTI BMSC DEPLOYMENT AND RELATED BROADCAST PROVISIONING SYSTEMS AND SERVICE CENTERS

摘要

A method of creating a delivery session for multiple broadcast multicast service centers may include providing a first create delivery session message for a first broadcast multicast service center. A service key identification and a key domain identification may be received from the first broadcast multicast service center, and a second create delivery session message may be provided for a second broadcast multicast service center. The second create delivery session message may include the service key identification and the key domain identification from the first broadcast multicast service center, and the second create delivery session message may include a duplicate indication.
