Cell handover method, equipment and system for monitor terminal

Abstract

The invention provides a cell handover method, cell handover equipment and a cell handover system for a monitor terminal. The cell handover method comprises the steps as follows: an idle monitor terminal in the current cell monitors a paging message transmitted from core network equipment via a source base station; the monitor terminal measures the current cell and an adjacent cell according to measurement configuration information contained in the paging message; when the results of cell measurement shows that measurement report is carried out, an RRC (Connection Reconfiguration) connection between the monitor terminal and the resource base station is established; based on the RRC connection, the monitor terminal submits a measurement report containing a mark of the adjacent cell determined as a target cell and another mark of a group determined as a target group for the core network equipment via the resource base station; and when the monitor terminal receives a handover instruction transmitted from the core network equipment according to the measurement report determining to carry out cell handover for the monitor terminal, the monitor terminal is switched to the target group of the target cell. According to the invention, the idle monitor terminal also can achieve cell handover.

Description

technical field [0001] The present invention relates to a cell switching method, device and system for monitoring terminals, and belongs to the technical field of long term evolution (Long Term Evolution, LTE for short) trunking communication. Background technique [0002] Trunking communication technology is a single-to-multipoint half-duplex wireless communication technology; LTE trunking communication technology is a trunking communication technology based on LTE technology. [0003] According to the existing LTE technical standards, when a terminal establishes a wireless link with a cell, the base station generally performs RRC connection reconfiguration for the user through Layer 3 Radio Resource Control (RRC) signaling, specifically in the RRC The connection reconfiguration message (RRC Connection Reconfiguration) carries measurement configuration information, so that the terminal can perform neighbor cell measurement according to the measurement configuration informat...

Since the RRC connection is established between the speaker terminal and the network side, the above method can still be used, and the speaker terminal sends a special RRC connection reconfiguration message for handover, measurement, and other configurations to achieve handover and other processes; however, monitoring There are a large number of terminals, and some monitoring terminals have established RRC connections with the network side, so they are in the connected state, while some monitoring terminals have not established RRC connections w
