Abstract
This application provides a communication method, apparatus, and system. The method includes: A first node communicates with a first donor node by using a first key, where the first key includes a key used for communication over an air interface and/or a key 1 used for communication over an F1 interface. After the first node receives first information from the first donor node, the first node maintains the first key and a second key in response to the first information, where the second key includes a key used for communication over an air interface between the first node and a second donor node and/or a key 2 used for communication over the F1 interface.
Claims20
A communication method, comprising:
- communicating, by a first node, with a first donor node by using a first key, wherein the first key comprises at least one of a key used for communication over an air interface or a key 1 used for communication over an F1 interface;
- receiving, by the first node, first information from the first donor node;
- and
- maintaining, by the first node, the first key and a second key in response to the first information, wherein the second key comprises a key used for communication over an air interface between the first node and a second donor node to which the first node hands over and a key 2 used for communication over the F1 interface.
A communication apparatus, wherein the apparatus comprises one or more processors and an interface, wherein the one or more processors are configured to enable the apparatus to:
- communicate with a first donor node by using a first key, wherein the first key comprises at least one of a key used for communication over an air interface or a key 1 used for communication over an F1 interface;
- receive first information from the first donor node;
- and
- maintain the first key and a second key in response to the first information, the second key comprises a key used for communication over an air interface between a first node and a second donor node to which the first node hands over and a key 2 used for communication over the F1 interface.
A non-transitory computer readable medium storing instructions that are executable by a computer to cause a first node to perform operations comprising:
- communicating with a first donor node by using a first key, wherein the first key comprises at least one of a key used for communication over an air interface or a key 1 used for communication over an F1 interface;
- receiving first information from the first donor node;
- and
- maintaining the first key and a second key in response to the first information, wherein the second key comprises a key used for communication over an air interface between the first node and a second donor node to which the first node hands over and a key 2 used for communication over the F1 interface.
