Abstract
Methods, media, and systems are provided for continuity of a telecommunications network service in an IP Multimedia Subsystem (IMS) layer providing telecommunications network services to devices located on an island. The IMS layer may comprise a Call Session Control Function (CSCF) or an application server. A diameter routing agent (DRA) or other diameter traffic controller associated with the CSCF transmits a request to a Home Subscriber Server (HSS) (e.g., that is located on a mainland). The CSCF, application server, or both have a skip HSS flag comprising instructions for connectivity loss with the HSS. Based on determining a loss of connectivity with the HSS, a Serving CSCF associated with the island is automatically selected or the Serving CSCF automatically transmits a response indicating the request was successful registering a user device, such that the user device continues working remotely on the island.
