<p>The disclosure discloses a method for switching a circuit switch domain service to a packet switch domain, configuring an HO-Proxy for handover to a PS domain of a target network, the method includes that: a service network base station system sends a CS domain service handover request for a UE to the HO-Proxy when the service network base station system determines to switch a CS domain service of the UE to the PS domain of the target network; and the HO-Proxy requests a target network control entity to switch the CS domain service of the UE to the PS domain of the target network, or switches the CS domain service of the UE to the PS domain of the target network. The disclosure further discloses a system for implementing the method. In the disclosure, when used for switching a CS domain service to a PS network, the HO-Proxy can preserve accurately the PS bearer resource for a corresponding (CS or PS domain) service of the UE, thereby implementing accurate and timely handover.</p> |
