Abstract: Embodiments of this application provide a user plane rerouting method and apparatus. The method includes: a first network element receives user plane rerouting trigger information sent by a second network element, where the user plane rerouting trigger information is sent when the second network element detects a preset service packet that matches a packet detection rule PDR, and the PDR is used to indicate matching information and an execution rule that are corresponding to the preset service packet triggering user plane rerouting. The first network element further performs the user plane rerouting based on the user plane rerouting trigger information.

Abstract: An application server switching method, applied to a scenario in which a handover occurs between user plane network elements corresponding to a terminal device, includes obtaining, based on a user plane network element of the user plane network elements after the handover and a correspondence between the user plane network element and an address of a local application server of one or more application servers deployed on a network, the address of the local application server corresponding to the user plane network element after the handover. The correspondence between the user plane network element and the address of the local application server is used to indicate the address of the local application server. The method also includes sending the address of the local application server corresponding to the user plane network element after the handover.

Abstract: The present invention provides a method and an apparatus for processing a bearer. The method includes performing depth packet inspection DPI processing on a traffic flow of a service according to a preset layer-7 protocol type matching rule. Alternatively, shallow packet inspection SPI processing is performed on a traffic flow of a service according to a preset layer-3 or layer-4 protocol type matching rule so as to obtain a DPI/SPI processing result. According to the DPI/SPI result and the preset matching rule, a service quality attribute parameter of the service is determined. The method further includes determining whether the service quality attribute parameter is the same as a service quality attribute parameter of an existing bearer, and if different, creating a dedicated bearer for the service.
