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.
