Problems solved by technology

[0003] Among them, when the user terminal is handed over to the target cell, if the signal of the target cell is not good enough, it may lead to premature handover of the user terminal, that is, after the user terminal is handed over from the source cell to the target cell, the wireless link between the user terminal and the target cell Unable to maintain that is RLF (Radio Link Failure, wireless link failure); thus reducing the handover success rate

Embodiment Construction

[0030] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031]One of the core concepts of the embodiments of the present invention is that, after receiving the measurement report from the user terminal, the source cell can delay the handover of the user terminal when it is determined that the user terminal is in a position where premature handover is likely to occur, thereby avoiding the user The terminal is handed over prematurely, thereby improving the handover success rate.

[0032] refer to figure 1 , which shows a flow chart of steps of an embodiment of a handover method in the present invention, which may specifically include the following steps:

[0033] Step 101, the source cell receives the measurement report reported by the user terminal, and determines the location of the u...

Abstract

The embodiment of the invention provides a switching method and device, and the method comprises the steps that a source cell receives a measurement report reported by a user terminal, and determinesa preset region to which the user terminal belongs according to the measurement report; obtaining premature switching information corresponding to the preset area; judging whether the premature switching information meets a premature switching condition or not; if yes, a measurement reconfiguration message is generated and sent to the user terminal, the measurement reconfiguration message is usedfor indicating the user terminal to execute event measurement again, and the triggering duration of the corresponding measurement event is prolonged to the target duration; and a measurement report reported by the user terminal again is received, a switching message is generated and sent to the user terminal, and the measurement report reported again is generated when the triggering duration of the measurement event reaches the target duration in the re-measurement process of the user terminal. According to the embodiment of the invention, when it is determined that the user terminal is in thearea where premature switching is likely to happen, the switching of the user terminal is delayed, and the switching success rate is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a switching method and a switching device. Background technique [0002] With the popularization of mobile Internet technology and mobile terminals, users can use user terminals to perform various services, such as surfing the Internet, video on demand, sending and receiving emails, downloading, etc. Handover is performed to keep the communication of the user terminal uninterrupted. [0003] Among them, when the user terminal is handed over to the target cell, if the signal of the target cell is not good enough, it may lead to premature handover of the user terminal, that is, after the user terminal is handed over from the source cell to the target cell, the wireless link between the user terminal and the target cell Failure to maintain is RLF (Radio Link Failure, wireless link failure); thus reducing the handover success rate.
