Service processing state information query method and apparatus thereof

The invention discloses a service processing state information query method and an apparatus thereof. The method comprises the following steps of receiving a query reference message sent by a service server, wherein the query reference message carries time needed by each processing node which completes an assigned service respectively; determining next information query time as the time after current processing node completion time and next node processing time ; when the next information query time arrives, sending an information query request to the service server, wherein the information query request carries a service identification of the assigned service; and receiving a information query response which is sent by the service server according to the information query request, wherein the information query request carries current service processing state information of the assigned service. By using schemes provided by embodiments of the invention, processing resource consumption during carrying out a service processing state information query.
