Embodiment Construction

[0045] In the prior art, if a cell handover occurs during a terminal call, the base station may directly initiate a redirection, resulting in direct dropped calls of the VOLTE user. In order to solve this problem, the method provided by the embodiment of the present application is: the base station side does not actively initiate a redirection process to the VOLTE user under any conditions, so as to ensure the continuous communication of the VOLTE user. In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0046] The terms "first", "second", "third" and "fourth" in the specification and claims of the present application and the drawings are used to distinguish different objects, rather than to describe a specific orde...

Abstract

The invention discloses a method and a base station for preventing a VOLTE user from call drop, and the method comprises: in the call process of the VOLTE user, if the situation of inter-system switching of a cell occurs, the base station receiving an event reported after a reference signal receiving power value of the VOLTE user exceeds a set threshold value; and if it is determined that a redirection process needs to be executed on the VOLTE user according to the event, stopping triggering the redirection process of the VOLTE user. According to the method provided by the invention, the technical problem that the user perception and the packet loss rate index are influenced due to direct call drop of the VOLTE user caused by cell switching and direct redirection initiated by the base station in the terminal call process in the prior art is solved.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method and a base station for preventing VOLTE users of network voice services from dropping calls. Background technique [0002] With the transformation and upgrading of network construction, because the 4G network is an all-IP data exchange network, the network structure is flat. Based on the characteristics of the 4G network, the long-term evolution (Long Term Evolution, LTE) network voice service (Voice over LongTerm Evolution, VoLTE) service is very different from the previous voice service. Some traditional voice service testing, evaluation and monitoring methods It is no longer applicable, and a comprehensive analysis of multiple network indicators is required to evaluate voice quality and user perception. [0003] During a voice call, if the user keeps moving and the location of the user changes constantly, during this process, if the user’s Refere...
