Switching command sending method and base station

Abstract

The invention discloses a transmit method for switching a command, which is applied in a long-term evolutionary system, and the method comprises that: a source base station transmits a first switching message to a terminal, and the first switching message refers to a target base station message with a variation period larger than a preset value; when affirming the terminal needing to initiate switching, the source base station transmits a switching command to the target base station; and the source base station receives switching response returned by the target base station and transmits a second switching message to the terminal according to the switching response of the target base station, and the second switching message refers to the target base station message with a variation period smaller than the preset value. The embodiment of the invention also provides a base station. By adopting the technical proposal of the embodiment of the invention, the contents of the first switching message and the second switching message are made clear, and the method for sending the switching message by two steps in an LTE system is led to become an operable technical proposal, thus perfecting the method, and guaranteeing the switching message to be timely, reliably and completely transmitted to the terminal.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for sending a handover command and a base station. Background technique [0002] With the development of communication technology, the requirements for network quality are increasing day by day, one of which is to realize the smooth handover of terminals (User Equipment, UE) between different cells [0003] In wireless networks such as Global System For Mobile Communication (GSM), UE switching between different cells is controlled by Radio Network Controller (RNC), and in Long Term Evolution (LTE) networks There is no RNC in the network, and the handover control is completed by the base station (Base Station, BS or NodeB). [0004] The source base station manages the source cell, and the target base station manages the target cell. The UE is currently in the source cell. When the source base station decides to handover the UE to the target cell according to the measurement rep...

Problems solved by technology

The above scheme of sending the handover command in two steps does not propose the specific content of the handover information sent in the first step, nor does it point out how to obtain this information. Therefore, according to the current way for LTE base stations to obtain handover information, the above technical solution is not an operable one. Technical solutions
