| 摘要 |
A subscriber unit (127), operating within a first communication system (120) receives emergency alarm support from a second, operationally independent, communication system (140), that provides support through a guest access mode. The subscriber unit (127) transmits a message to the second system (570), the message including the emergency alarm call and supplementary information that identifies the source of the emergency alarm call. The second system (140) receives the message (610), determines source identification information for the emergency alarm call (620), and communicates the emergency alarm call to the first system based on the source identification information (630). Preferably, the subscriber unit (127) maintains an emergency resource list (322) for selecting recipients for handling emergency alarm calls.
