Abstract

The invention provides a call completing rate improving method and a base station. The method comprises the following steps: after receiving a VoLTE voice call request initiated by a terminal, receiving an eSRVCC A2 measurement report reported by the terminal; wherein the eSRVCC A2 measurement report comprises a serving cell reference signal receiving power threshold measured by a terminal; underthe condition that an SIP 180 message sent by a called terminal corresponding to the VoLTE voice call request is not received, comparing the reference signal receiving power threshold of the serving cell with a preset A2 threshold; when the reference signal receiving power threshold of the serving cell is smaller than the preset A2 threshold, comparing the reference signal receiving power threshold of the serving cell with a weak field calling judgment threshold; and switching a network connected with the terminal to a 2G network when the reference signal receiving power threshold of the serving cell is smaller than the weak field calling judgment threshold. Through adoption of the method, the call of the user in a black hole coverage scene can be put through, and the perception of networkcommon users can be enhanced effectively.

Description

technical field [0001] The invention relates to the technical field of voice calls, in particular to a method for improving call completion rate and a base station. Background technique [0002] There is a coverage difference of about 8 dB between data services and VoLTE (Voice over Long Term Evolution, long-term evolution voice bearer) voice services. [0003] For users in LTE (Long Term Evolution, long-term evolution) network weak field scenarios, each time a VoLTE call is initiated, there is a high probability that bSRVCC (Single Radio Voice Call Continuity) will occur before ringing. Since both the terminal and the network do not support bSRVCC, the call will fail, affecting the connection of the user's voice call under the network, and it is easy to cause complaints due to poor user perception. [0004] TD-LTE (Time Division Long Term Evolution, Time Division Long Term Evolution) 4G (the 4thGeneration mobile communication technology, the fourth generation mobile commun...
