1. A method for security activation, wherein the method comprises:
selecting based on a context of a terminal device, by a first access network device in a first communication standard, a second access network device that is in a second communication standard and that supports user plane security protection, wherein the first access network device is a master access network device in dual connectivity of the terminal device;
requesting, by the first access network device, the second access network device to allocate a resource for the dual connectivity of the terminal device,
sending, by the first access network device, a user plane security policy to the second access network device;
receiving, by the first access network device, identification information of a bearer and a security activation status from the second access network device; and
sending, by the first access network device, the identification information of the bearer and the security activation status to the terminal device, wherein the security activation status indicates whether to enable at least one of user plane encryption protection or user plane integrity protection of the bearer.
