Embodiment Construction

[0084] The application will be described in further detail below in conjunction with the accompanying drawings. The specific operation methods in the method embodiments can also be applied to the device embodiments or system embodiments. Wherein, in the description of the present application, unless otherwise specified, "at least one" means one or more, and "multiple" means two or more. " / " means or, for example, A / B can mean A or B; "and / or" in this article is just a description of the relationship between associated objects, which means that there can be three relationships, for example, A and / Or B, can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, and c can represent: a, b, c, a and b, a and c, b and c, or a, b and c, wher...

Abstract

The embodiment of the invention provides a safety protection method and device and access network equipment, relates to the technical field of communication, and is used for solving the problem that the safety protection of a user plane cannot be started as required in the prior art. The method comprises the following steps: the first access network device receives a first message from a second access network device, wherein the first message carries a user plane security policy; the user plane security policy is used for indicating user plane security protection type to be started of the first access network device, and the first access network device determines a user plane security algorithm and a user plane key corresponding to the user plane security algorithm according to the user plane security strategy if the first access network device can identify the user plane security protection type to be started; or, if the first access network device cannot identify the user plane security protection type to be started, the first access network device selects a default user plane security algorithm and determines a user plane key corresponding to the default user plane security algorithm.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a security protection method, device and access network equipment. Background technique [0002] In the dual connection architecture, the terminal can access the master station and the slave station at the same time. In a long term evolution (long termevolution, LTE) dual connectivity architecture, both the master station and the slave station are evolved NodeBs (evolved NodeB, eNB or eNodeB) in a fourth generation (4th generation, 4G) network. In this architecture, the master station can be represented as master eNodeB or MeNB, and the slave station can be represented as secondary eNodeB or SeNB. Similar to LTE, a fifth generation (5th generation, 5G) network may also support dual connectivity technology. In the dual connection architecture of the 5G network, both the master station and the slave station can be the next generation node basestation (gNB) of...
