ABSTRACT:
Active sessions and dialogs may be moved between connections and P-CSCFs. For example, in some embodiments either new bindings may be created with a different connection for a Public User ID or the UE may re-register one or more specific bindings for a Public User ID from one connection to another. The capabilities improve service continuity when handing over between IP-CANs. FIG.13illustrates exemplary messaging for moving bindings to a new connection for a Private User ID between UE (1305) and P-CSCF (1307) when the UE (1305) is in a visited IP-CAN, that is, visited network (1303). The UE (1305) invokes the unprotected global seamless re-registration of the embodiments via an unprotected initial registration procedure wherein the UE (1305) includes a “seamless-ims” parameter in the Require and Proxy-Require headers of the REGISTER request (1313). The S-CSCF (1311) provides the capability to subsequently re-register bindings over new or existing connections.
