The invention discloses an SGW (Service Gate Way) equipment selection method and an SGW equipment selection device, which are applied to an MME (Mobility Management Entity). The method comprises the following steps: acquiring and storing multiple configurations containing SGW equipment addresses, selecting a corresponding SGW equipment address from the current highest-priority or lowest-priority configuration according to the priority order of the SGW equipment addresses, and sending the SGW equipment address to an eNode B; receiving error information fed back by the eNode B and indicating that link connection between the eNode B and SGW equipment using the current SGW equipment address fails, recording the error, and updating the number of errors of the current SGW equipment address and the total number of errors of all the SGW equipment addresses in the current configuration; when the number of errors of the current SGW equipment address reaches a preset threshold and the total number of errors does not reach a preset threshold, selecting a next-priority SGW equipment address from the current configuration and sending the SGW equipment address to the eNode B; and when the total number of errors reaches a preset threshold, determining that the current configuration is not credible, and selecting an SGW equipment address according to the priority from a next-priority configuration and sending the SGW equipment address to the eNode B.
