Abstract

The embodiment of the invention discloses a synchronization method and a synchronization device. The synchronization method comprises the steps of reading an adjacency information table preset by a current node, wherein the adjacency information table comprises the address information of an upper node; sending heartbeat request information to the address information of the upper node; if receiving the heartbeat response information based on the heartbeat request information, sending caching information to the upper node, wherein the caching information comprises data information within a preset time slot; sending a user subscription information request to the upper mode; and receiving the user subscription data information which is sent by the upper mode and belongs to the current node, and updating the data according to the user subscription data information of the current node. According to the synchronization method and device, through synchronizing data information between the nodes in time, the accordance of each node data in the network can be ensured, the cross-regional roaming problem in the miniaturized LTE network can be effectively solved, and the network building cost and the network resources can be saved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a synchronization method and device. Background technique [0002] At this stage, with the continuous development of communication technology, in more and more specific regions and industries, a miniaturized LTE (Long Term Evolution, Long Term Evolution) communication network is used for data communication to achieve an end-to-end communication solution. [0003] However, when a large area requires cross-regional network interconnection, it is necessary to ensure that data in different regions are consistent. Due to cost and resource constraints, small LTE networks cannot achieve data consistency by deploying HSS (Home Subscriber Server, Home Subscriber Server) network element entities like traditional operator networks. Therefore, how to achieve data consistency across regions in a small LTE network is an urgent problem to be solved. Contents of the invention ...
