The base station according to claim 6, wherein the direct routing information deployed in the access network comprises: deploying second direct routing information at the management control center in the access network, the second direct routing information The information includes: the base station direct topology represented by the base station identifier, and the service type information and user equipment identifier corresponding to each base station identifier; the routing module includes: A sending unit, configured to send a direct routing query request to the management control center, where the direct routing query request includes the source base station identifier, the target user equipment identifier, and the service type information; The receiving unit is configured to receive the direct route query result fed back by the management control center after querying the second direct route information, so as to determine whether to use the data direct route for the communication interaction, specifically including: the management control center Determine the target base station identity corresponding to the target user equipment identity according to the user equipment identity corresponding to each base station identity, and according to the base station direct topology structure and the service type information respectively corresponding to the source base station identity and the target base station identity Determine whether there is a direct data route provided for the service corresponding to the service type information between the source base station and the target base station, and if so, feed back a query result including the identity of the target base station to the source base station, otherwise, Feedback query results without direct routing. 10. The base station according to claim 9, further comprising: An update module, configured to send an update message to the management control center after learning that the local user information list has been updated, the update message including: a source base station identifier and a user equipment identifier to be updated, so that the management control center Updating related information in the second through routing information according to the update message.
