Abstract

An embodiment of the present invention provides a call connection method, comprising: a CSFB Proxy configuring a correlation table of the location area identifier (LAI) and the visited mobile switch center (VMSC) number; receiving a combined location update request message sent by a mobile management entity (MME), and determining, according to an LAI carried in the request message, a VMSC number corresponding to the LAI; constructing a Provide Roaming Number (PRN) request message, the VMSC number being encapsulated into the PRN request message; and sending the PRN request message to a determined VMSC to trigger the VMSC to initiate a data recovery process to obtain user data, so that upon receiving a call request, the VMSC establishes a call path according to the user data to complete call connection. Accordingly, embodiments of the present invention further provide a CSFB Proxy, a VMSC, and a call connection system, thereby reducing steps of the call process and the call delay and improving the user experience.
