The present invention relates to the field of communications, and particularly, to a method and device for fixing resource leakage. The method for fixing resource leakage comprises: a resource providing device receiving a resource acknowledgment request message from a resource request device, the resource acknowledgment request message carrying a first piece of indication information, and the first piece of indication information being used for indicating resources that have been obtained by the resource request device from the resource providing device; the resource providing device searching, according to the first piece of indication information, for resources that have been allocated by the resource providing device to the resource request device but have not been obtained by the resource request device; the resource providing device initializing the found resources to an unallocated state. The present invention is advantageous in that leaked resources can obtain a chance of being re-allocated so as to fix resource leakage.
