Abstract

Embodiments of the present application disclose a distributed lock scheduling method and apparatus. The method comprises the following steps: when a service process is started, a distributed lock anda session corresponding to the service process are created; if the service process fails and is disconnected from the scheduling process of the service process, and the scheduling process is restartedand a new scheduling process is generated, the new scheduling process obtains the identification information of the service process. The new scheduling process acquires at least one distributed lockassociated with the identification information according to the identification information, and acquires at least one historical session associated with the distributed lock according to the at leastone distributed lock, the at least one historical session including the session. The embodiment of the method and the device can ensure the normal working state of the client and maintain the continuity of the packet data access service of other service clients.
