Embodiment Construction

[0051] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0052] The small cell handover method provided by the first embodiment of the present invention, such as image 3 shown, including:

[0053] Step S1, the macro base station judges whether the user equipment UE needs to perform small cell handover;

[0054] Step S2, if it is determined that the UE needs to perform small cell handover, the macro base station controls the UE to connect to the target small cell;

[0055] In step S3, after the UE is successfully connected to the target small cell, the macro base station instructs the camping small cell to release the connection to the UE.

[0056] The small cell handover method provided by the present invention maintains ...

Abstract

The invention relates to the communication technology field and particularly relates to a small cell switching method and system. The method comprises steps that whether user equipment needs small cell switching is determined by a macro base station; if the UE is determined to need small cell switching, the UE is controlled by the macro base station to connect with a target small cell; after the UE is successfully connected with the target small cell, a resident small cell is indicated by the macro base station to release connection with the UE. Through the method, seamless soft switching of the UE from the resident small cell to the target small cell can be realized, continuity of user surface data transmission in a switching process is guaranteed, and user mobility demands in the super dense network are satisfied, and user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a small cell handover method and system. Background technique [0002] Ultra-dense networking will be the main technical means to meet the demand for mobile data traffic in 2020 and in the future. Ultra-dense networking can achieve higher spectrum reuse efficiency through more "intensive" wireless network infrastructure deployment, and at the same time, through the expansion of high-band spectrum resources, the system capacity can be increased by hundreds of times in local hotspot areas . However, as the deployment density of small cells increases, the number of handovers between mobile users between cells will increase significantly, which will lead to excessive signaling overhead and degradation of service quality (due to link interruption during the handover process leading to TCP performance deterioration), and more cases of low SINR to avoid the "ping-...
