Service control method and apparatus

摘要

In the field of mobile communications, embodiments of the present invention disclose a service control method and apparatus. A user equipment has established a circuit switched bearer, and the user equipment initiates a session with a third party. The method includes: receiving, by a service centralization and continuity application server SCC AS, early session media information and sending the early session media information to a circuit switched network in a form of regular session media, so that the circuit switched bearer is used for an early session; and receiving, by the SCC AS, an off-hook signal of the third party and sending regular session media information of the third party to the circuit switched network, so that the circuit switched bearer is used for a regular session.

1. A service control method, comprising:
receiving by a service centralization and continuity application server (SCC AS) in an IP multimedia subsystem (IMS) network, from a first user equipment a first session initiation protocol (SIP) message for establishing an IMS centralized service (ICS) session with a second user equipment; receiving, by the SCC AS in the IMS network, early session media information; sending, by the SCC AS in the IMS network, a second SIP message carrying the early session media information to a media gateway control device, wherein the early session media information is carried in the second SIP message in a form of regular session media information to indicate the media gateway control device to use an existing circuit switched bearer to transmit early session media corresponding to the early session media information to the first user equipment, wherein the existing circuit switched bearer is established between the first user equipment and the media gateway control device for a session between the first user equipment and a third user equipment; receiving, by the SCC AS in the IMS network, an off-hook signal from the second user equipment; and after receiving the off-hook signal, sending by the SCC AS in the IMS network the regular session media information of the second user equipment to the media gateway control device.
