Abstract: In a communication system, a service centralization and continuity application server (SCC AS): receives a first SIP message for establishing an IMS centralized service session; receives early session media information; and sends a second SIP message carrying the early session media information to a media gateway control device. The early session media information is carried in the second SIP message in a form of regular session media information, thus the media gateway control device uses an existing circuit switched bearer to transmit early session media to a first user equipment. The existing circuit switched bearer is established under control of the media gateway control device for a session between the first user equipment and a third user equipment. The SCC AS receives an off-hook signal from the second user equipment, and sends the regular session media information to the media gateway control device.

Abstract: In the embodiments of the invention, a user equipment sends an I1 Invite message to a service centralization and continuity application server. The I1 Invite message includes a service control switching request indication and a Session Initiation Protocol (SIP) dialog identifier of an Internet Protocol multimedia subsystem (IMS) session. The service centralization and continuity application server searches for the IMS session according to the SIP dialog identifier, and sends a message indicating that a service control is switched to the user equipment.

Abstract: Embodiments of the present invention disclose a method for a single card dual standby user equipment to camp on a network and a user equipment, so as to reduce power consumption of a user equipment. The method in the embodiment of the present invention includes: when a circuit switched domain CS domain of a UE camps on a second-generation mobile communications technology 2G/third-generation mobile communications technology 3G network and a packet switched domain PS domain camps on a long term evolution LTE network, executing, by the UE, a routing area update process of the PS domain of the 2G/3G network if the UE meets a preset first condition, so as to make the PS domain of the UE camp on the 2G/3G network; and after the PS domain of the UE camps on the 2G/3G network, turning off an LTE radio frequency unit.
