SRVCC switching failure punishment processing method and device

Abstract

The embodiment of the invention discloses an SRVCC switching failure punishment processing method and device. The method comprises the following steps: if a switching failure punishment switch is in an on state and the number of preparation failures of switching all cells of a base station to an external neighbor cell within a switching failure statistical duration is greater than a switching failure number threshold, setting the state of a current neighbor cell to be a state in which the current neighbor cell is not allowed to be switched; and after the current neighbor cell is set to be a state in which the current neighbor cell is not allowed to be switched for the switching failure punishment duration, taking the current neighbor cell as the candidate cell of the SRVCC switching again.By setting the SRVCC switching failure punishment switch, the switching failure statistical duration, a switching failure frequency threshold value and a switching failure punishment duration, when the number of preparation failures is larger than the threshold value of the number of switching failures, the cell is set to be a cell not allowed to be switched, the cell is recovered to be the candidate cell after the punishment duration of the switching failures ends, SRVCC switching to a problematic cell can be stopped in time, switching to the problematic cell cannot be forbidden, the switching success rate can be effectively improved, and meanwhile the KPI of the network is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for punishing SRVCC handover failure. Background technique [0002] Under the LTE (Long Term Evolution, Long Term Evolution) system, when the signal in the 4G cell becomes poor, voice users can interoperate with different systems in the 2G cell through the SRVCC strategy. Using the handover algorithm, when the measurement report of b1 or b2 carries a known GERAN (GSM EDGE Radio Access Network, GSM / EDGE radio access network) neighboring cell, the handover process to the GERAN neighboring cell can be performed. However, in current field applications, it is found that for some reasons, for example, the signal of a certain GERAN cell deteriorates; or the LAC (Location Area Code, location area code) or RAC (Routing Area Code, routing area code) of the GERAN neighbor cell configured on the base station side and other parameter...

Problems solved by technology

If any one of the conditions is not met, the SRVCC switchover will fail

[0008] The existing SRVCC handover implementation is designed according to the SRVCC protocol, without considering the abnormal scenarios in the actual application environment, such as resource allocation failure after the target cell receives the handover preparation, and the target cell cannot recognize the relevant information in the handover request, etc.

For these scenarios, the existing technology cannot intelligently handle them, which can only lead to an increase in the failure rate of SRVCC handover and deterioration of indicators
