Problems solved by technology

[0003] However, heterogeneous networks also bring many problems
For example, the handover efficiency of the mobile terminal from the source cell to the target cell is greatly affected, and the handover failure probability of the mobile terminal also increases
At present, in order to improve the handover efficiency of the mobile terminal from the source cell to the target cell and reduce the handover failure probability of the mobile terminal, various techniques have been adopted, but this often leads to a higher ping-pong handover probability of the mobile terminal

Embodiment Construction

[0072] Embodiments of the present invention will be described below with reference to the drawings. It should be noted that representation and description of components and processes that are not related to the present invention and known to those of ordinary skill in the art are omitted from the drawings and descriptions for the purpose of clarity.

[0073] Combine below figure 1 To describe the handover process of the mobile terminal from the source cell to the target cell. figure 1 It is a schematic diagram showing a handover process of a mobile terminal from a source cell to a target cell.

[0074] Before time t1, the mobile terminal is in state 1 and detects, for example, whether the conditions for entering event A3 are fulfilled. At time t1, the mobile terminal detects, for example, that the conditions of the entry event A3 are fulfilled. Those skilled in the art should understand that the above-mentioned detection by the mobile terminal of whether the conditions of e...

Abstract

Disclosed are a device and method in a radio communication system. The device comprises: an acquisition unit for use in acquiring a signal quality of a mobile terminal relative to a source cell; an assessment unit for use in assessing the degree of change in the signal quality of the mobile terminal relative to the source cell on the basis of multiple signal qualities of the mobile terminal relative to the source cell acquired at every predetermined time interval; and, a triggering unit for use in triggering, on the basis of the degree of change in the signal quality of the mobile terminal relative to the source cell, the mobile terminal to submit a measurement result.

Description

technical field [0001] The present invention generally relates to the field of wireless communication, and more particularly relates to devices and methods in Universal Mobile Telecommunications System (UMTS) Long Term Evolution (LTE) and its subsequent evolution (LTE-A). Background technique [0002] The concept of heterogeneous networks (Heterogeneous Networks) was first proposed in 3GPP Rel-10. The heterogeneous network introduces low-power access points in the macro cell to shorten the distance between the user's mobile terminal and improve the user's service quality, thereby increasing the capacity of the entire network. Therefore, in a heterogeneous network, macro cells will mainly provide network coverage, while low-power access points located in hot spots will mainly provide high-speed, high-quality service bearing. [0003] However, heterogeneous networks also bring many problems. For example, the handover efficiency of the mobile terminal from the source cell to ...
