The present invention discloses a service processing method and device, including: determining, by a serving gateway SGW, that an exception occurs in a packet data gateway PGW; obtaining a policy for deleting a packet data network PDN connection established between the SGW and the PGW; deleting a PDN connection between the SGW and the PGW according to the policy for deleting a PDN connection; and sending a deletion request message to a mobility management entity MME, where the deletion request message includes identity information of the deleted PDN connection and is used for notifying the MME to delete a PDN connection corresponding to the identity information. In this way, when determining that an exception occurs in the PGW, the SGW no longer needs to send the fact that an exception occurs in the PGW to the MME, thereby reducing a signaling transmission amount in a system, and simplifying a service processing procedure. Moreover, because different deletion policies are used, service processing is accelerated, service processing efficiency of the system is further improved, and user experience is improved.
