Method of mobility management, system thereof and device thereof

Abstract

An embodiment of the invention relates to the wireless communication technology field, especially relating to a method of mobility management, a system thereof and a device thereof which are used for enabling a base station to know whether a target cell supports a new characteristic or not in M2M (machine-to-machine) communication. The embodiment of the invention provides the method of mobility management. The method comprises the following steps: a first network side device determines first notification information used for expressing the capability of a cell managed by a first network side device or expressing the capability of the first network side device, and sends the first notification information; a second network side device receives the first notification information and determines the capability of the cell managed by the first network side device according to the first notification information. According to the embodiment, capability of a cell managed by one network side device can be notified to other network side devices, thus the base station can know whether the target cell supports the new characteristic or not in M2M communication.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and in particular to a method, system and equipment for mobility management. Background technique [0002] Mobility management refers to a series of operations for the user equipment to switch the residence or working cell during the movement, including the operations of the network and the user equipment. These operations can ensure that the user equipment is in better wireless signal coverage, ensure business continuity, and enable users to get a better experience. Common mobility management operations include cell reselection and cell handover. The cell that the user equipment resides in in the idle state changes during cell reselection, and the working cell that works in the connected state during cell handover changes. For cell reselection, the network side does not participate, and the user equipment measures neighboring cell signals, and according to certain criteria, ...

AI Technical Summary

Problems solved by technology

According to the current agreement, the base station cannot know whether the cell under the jurisdiction of the adjacent base station supports small bandwidth, so it is impossible to provide this information when configuring the neighbor list

In this way, the low-bandwidth user equipment cannot know which neighboring cells support small-bandwidth cells / cells that do not support small-bandwidth, which may cause blind measurement, power consumption, and even cell reselection failure.

In the scenario of connection status, in the scenario of cross-base station handover, the source base station does not know which cells of the target base station are cells that support small bandwidth / cells that do not support small bandwidth. The possible problem is that the source base station is deciding to switch the target cell Switch the low-bandwidth user equipment to a network that does not support low-bandwidth at the time, causing the user equipment to fail to work

[0008] To sum up, in the current M2M communication, for the neighboring cells under the jurisdiction of different base stations, the base station cannot know whether the cells under the jurisdiction of the neighboring base stations support new features.
