The invention relates to a method and a system for limiting concurrency before the turn, the method comprises the following steps: MSC launch position application message to HLR; HLR application received position information, access to the called number the turn count and preset before the turn count threshold, Dangdang before the turn count is greater than or equal to a preset threshold before the turn count HLR, refused to return response message to the MSC, disable the called number before the turn. The standard home location register (HLR) and the mobile switching center (MSC) with the control of the user before the turn number, so as to effectively reduce the flood to malicious; for some suspicious number of alarm reporting, which can effectively prevent the occurrence of fraud behavior of users, improve user security, achieve for the purpose of consumer protection.
