Abstract

The invention discloses a method used for establishing double-connection in a communication system. The method is characterized in that a second base station is used to receive a switching request from a first base station connected with the user equipment; the second base station is used to respond to the switching request, and is used to establish the connection with the user equipment; the second base station can be used to determine a third base station according to the received measurement results, and the establishing of the connection between the third base station and the user equipment can be facilitated, and therefore the double-connection can be provided for the user equipment. The switching trigger condition of the switching request comprises the mobility enhancement or the establishing of the double-connection request. The invention also provides the corresponding base stations and the user equipment.

Description

Technical field [0001] The embodiments of the present invention generally relate to the field of wireless communication, and more specifically, to a handover method, user equipment, and base station for dual connectivity. Background technique [0002] Handover technology is a common and important technology in the field of mobile communications. There are multiple conditions that trigger the switch. According to the current specification (3GPPTS36.423), there are the following handover trigger conditions: [0003] [0004] These four trigger conditions can be divided into two categories: one is triggering handover due to load balancing; the other is triggering handover due to wireless link conditions (usually when the wireless link conditions become worse). In Release12, dual connectivity was introduced. The purpose of introducing dual connectivity is at least to enhance mobility. Therefore, in addition to load balancing or poor wireless link conditions, there are situations wh...
