Common EAS announcement procedure enables an EES to exchange selected common EAS information with other EES(s).
Step 1.
The announcing EES sends Announce common EAS request message to the receiving EES. The request message includes the requestor identifier [EESID], the security credentials, the selected common EAS information, the announcing EES endpoint, and the Application group ID.
Step 2.
Upon receiving the request from the announcing EES, the receiving EES checks if the announcing EES is authorized to provide the selected common EAS. The receiving EES stores the received selected EAS information and announcing EES endpoint along with the Application group ID.
Step 3.
If the processing of the request was successful, the receiving EES sends Announce common EAS response to the announcing EES indicating a successful status; otherwise, the receiving EES shall indicate a failure status and include appropriate reasons.
