Abstract: A charging system switching method and an apparatus such that an online charging system or a customer relationship management system may initiate charging system switching of a specific service, and may switch any service from an original charging system to a new charging system in real time, without switching all users on the original charging system onto the new charging system. Therefore, a smooth switching between multiple charging systems is supported, and in addition, multiple charging systems may perform charging for different services of a same user, thereby implementing coexistence of different charging systems.

Abstract: Embodiments of the present invention disclose a method for providing a service, a service broker, and a policy and charging rules function apparatus. The method includes: receiving a service request; determining, according to the service request, at least one AF associated with the service; determining QoS requirement information of each AF; sending a QoS authorization request to a PCRF, where the QoS authorization request carries the QoS requirement information of each AF; receiving an authorization success answer sent by the PCRF so as to provide the service through the at least one AF, where the authorization success answer carries authorization to the QoS requirement information of each AF. According to the method and the apparatus in the embodiments of the present invention, QoS requests are controlled by using an SB in centralized mode so that the development and operation costs can be reduced.
