Problems solved by technology

The entire process above takes a long time, so when the connection between the user equipment and the master node is abnormal, it will cause a long-term interruption of data transmission and signaling transmission, thus reducing system performance and affecting user experience
In addition, even after cell selection or cell reselection, the user equipment still establishes a connection with the original primary node, and the primary node still needs to reconfigure the secondary node for the user equipment, which increases the signaling load of the network and reduces the efficiency of signaling configuration

Embodiment Construction

[0040] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0041] In the description of the present application, unless otherwise specified, " / " means "or", for example, A / B may mean A or B. The "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" means one or more, and "plurality" means two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

[0042] It should be noted that, in this application, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. ...

Abstract

The invention relates to the technical field of wireless communication, in particular to a communication method, device and system. The communication method comprises: user equipment sends a first message to a secondary base station, the first message being used for indicating that an abnormal condition occurs in connection between the user equipment and a primary base station; and the user equipment receives a second message sent by the secondary base station, wherein the second message is used for indicating whether to recover the connection with the primary base station. The invention is toquickly recover the connection between user equipment and the primary base station through the interaction between the user equipment and the secondary base station, thereby reducing the interruptionof data transmission and / or signaling transmission, and improving the system performance and user perception.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a communication method, device and system. Background technique [0002] The dual connectivity technology in the technical field of wireless communication refers to a technology in which user equipment communicates using radio resources provided by at least two connected network nodes (primary node and secondary node). Using the dual connectivity technology can utilize more radio resources to provide data or signaling transmission for user equipment, thereby improving radio resource utilization, reducing system switching delay, and improving user and system performance. [0003] Due to changes in air interface conditions, abnormal conditions may occur in the connection between the user equipment and the master node or the slave node, so that data or signaling transmission cannot be performed. Since the control plane of the user equipment is usually m...
