Abstract: A communication method comprises that if a policy control device does not support setup of an Internet Protocol (IP) multimedia subsystem (IMS) default bearer during setup of an IMS default bearer for a terminal, the control plane gateway sends second indication information to a user plane gateway, where the second indication information indicates the control plane gateway bypasses the policy control device. When the user plane gateway receives an IMS session request from the terminal and determines that the control plane gateway bypasses the policy control device, the user plane gateway sends first indication information to the control plane gateway, and the first indication information indicates the control plane gateway to send, to the policy control device, a first request to request to establish a mapping relationship between the terminal and the control plane gateway such that an IMS session can be set up between terminals.

Abstract: Embodiments of this application provide a communication method and apparatus, and relate to the communications field. The method includes: A user plane network element receives, from a control plane network element, information indicating a first policy, where the first policy indicates to maintain, when the user plane is disconnected from the control plane, continuity of a service of the user plane; and the user plane network element runs the service according to the first policy. In this way, the user plane network element may be indicated in advance to maintain, when the user plane is disconnected from the control plane, the continuity of the service of the user plane network element, to avoid service disconnection and meet an application scenario having a high requirement on service continuity.
