摘要：Embodiments of the present invention disclose a method, an apparatus, and asystem for service control via an I1 interface. The method includes: sending a SessionInitiation Protocol Invite message to a user equipment through a Gm interface; if

receiving a response message returned by the user equipment, where the responsemessage indicates that the user equipment chooses to use a circuit switched bearer anduse an I1 interface for control, sending an I1 Invite message to the user equipmentthrough the I1 interface, where I1 Invite message carries information indicating that Gminterface control falls back to the I1 interface control and information used to associatethe Session Initiation Protocol Invite message. With the technical solution, a replaceheader field of the I1 Invite message is used to carry information indicating that Gminterface control falls back to the I1 interface control and information used to associatethe Session Initiation Protocol Invite message, so the calling and called user identifiersmay be omitted, which reduces the overheads of the I1 protocol message.
