Embodiment Construction

[0039] As above, the EN dual connection establishment method in the prior art has the problem that the eNB and the gNB are too tightly coupled, which is not conducive to the introduction of new technologies and the maintenance of the eNB and the gNB.

[0040] In order to solve the above problems, the eNB in ​​the embodiment of the present invention receives the NR measurement configuration from the gNB, and transparently transmits it to the user equipment, and then transparently transmits the received NR measurement report to the gNB accordingly, so that the gNB interprets the NR measurement report, Then, when the eNB directly uses the NR measurement report interpreted by the gNB to determine that EN dual connectivity can be established, it transparently transmits the access resource configuration obtained from the gNB to the user equipment, so that the user equipment adopts the access resource configuration Establish a 5G network connection with the gNB to realize the establis...

Abstract

The invention discloses an EN dual connection establishing method, an eNB, and a gNB, and the method includes the steps: establishing a 4G network connection with user equipment; transmitting a request for the NR measurement configuration to the gNB; and transmitting the received NR measurement configuration to the user equipment; transmitting an NR measurement report to the gNB that replies to the NR measurement configuration when receiving the NR measurement report; receiving the interpreted NR measurement report; determining a unique gNB according to the load status of the gNB and the strength of the NR measurement report; transmitting the request for accessing the resource configuration to the unique gNB when the EN dual connection is established; transmitting the access resource configuration to the user equipment, so that the user equipment adopts the access resource configuration and the unique gNB to establish a 5G network connection, thereby achieving the establishment of theEN dual connection. Through the above scheme, the method reduces the degree of coupling between the eNB and the gNB, facilitates the introduction of new technologies and the maintenance of the eNB andthe gNB.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, relate to a method for establishing EN dual connectivity, an eNB, and a gNB. Background technique [0002] The current 5G new radio (New Radio, NR) standard is under discussion, and the goal of the first phase is to deploy a 5G network with the help of a 4G network, that is, a non-independent (None Stand Alone, NSA) networking mode. In this NSA networking mode, user equipment (User Equipment, UE) resides under a base station (eNB) of a 4G network. When data transmission occurs, a connection (4G connection) between the UE and the eNB is established first, and then the eNB decides whether to establish an EN dual connection (LTE NR Dual Connectivitiy, EN DC) for the UE. If so, the UE establishes a 5G network connection with a base station (gNB) of the 5G network with the assistance of the 4G network connection, thereby realizing EN dual connectivity...
