The invention discloses a rapid query method for dynamic position information of a mobile network entity. According to the method, a distributed container with a hierarchical nested structure is adopted to process registration and query of network entity position information; The method comprises the following steps: 1) after a network entity moves and is connected to a network attachment point and obtains new network address distribution, the number of stages of a registration container is determined according to the mobile service attribute parameters of the network entity, and then the newposition information of the network entity is registered to the container of the corresponding stage where the network entity is located at present; Wherein the position information at least comprisesthe current network address information of the network entity; 2) when the network forwarding equipment knows that the network entity is currently unreachable, new position information of the networkentity is inquired from a container where the network entity is located before movement; And after receiving the query request, the container where the network entity is located obtains new positioninformation of the network entity by searching in the container of the container and the same-level neighbor container set.
