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.illustrates exemplary messaging for moving bindings to a new connection for a Private User ID between UE () and P-CSCF () when the UE () is in a visited IP-CAN, that is, visited network (). The UE () invokes the unprotected global seamless re-registration of the embodiments via an unprotected initial registration procedure wherein the UE () includes a 'seamless-ims' parameter in the Require and Proxy-Require headers of the REGISTER request (). The S-CSCF () provides the capability to subsequently re-register bindings over new or existing connections.
