A method and device for saving the state of the buffer queue, and a method and device for merging bill, the said method for saving the state of the buffer queue comprises: distributing a bill identifier (ID) in advance for each bill which needs to wait in bill group of the buffer queue, saving the bill ID of the bill added recently into the buffer queue in the bill ID queue; saving the bill information of the bill added recently in the buffer queue as a temporary bill file, saving the bill ID queue as an ID queue file. When saving the state of the buffer queue by using the present invention, only the bill ID queue is updated and the bill added recently in the buffer queue is saved, the buffer queue doesn't need to be saved entirely, so the time for processing the bill is reduced, and the processing rate for merging the bill is quickened. |
