Abstract
A method, network device, and network system for implementing the Voice Call Continuity (VCC) service are provided. The method includes: receiving an Initial Detection Point (IDP) message from a Mobile Switching Center (MSC); querying whether an address of a Service Control Point (SCP) of a user is null; if the address of the SCP is not null, sending the IDP message to the SCP and interacting with the SCP; and detecting whether a subsequent message from the SCP is a Connect or Continue message; if the subsequent message from the SCP is the Connect or Continue message, copying the Connect or Continue message to a new Connect message and sending the new Connect message to the MSC for implementing the VCC service. According to the present invention, a new SCPvcc is used to support the VCC service, thus implementing the VCC service for all mobile users.
