Abstract: An emergency notification service is described that is delivered using an evolved multimedia broadcast-multicast service (eMBMS). An emergency notification is sent out to user equipment (UE) in affected areas. In response to receiving the emergency notification, the UE searches the appropriate emergency multicast service acquisition information for multiple potential types of available emergency content that is provided by the eMBMS system in the network and tunes to the eMBMS to receive the emergency content. In selected aspects, the transmitted information, including the notifications and content may be scrambled using the same cell ID for each of the cells transmitting the same content. This improves the quality of the transmitted signals allowing for more reliable receipt and decoding by the receiving UEs.
