MESH-TYPE NETWORK AND BASE STATION FOR IMPROVING TERMINAL INFORMATION MANAGEMENT METHOD AND COMMUNICATION METHOD IN MOBILE COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To easily realize mobile communication through the efficient use of an L3 communication tunnel between each base station in a mesh-type network.

SOLUTION: Communication is performed via a mesh-type network 10 between a mobile terminal 16a and a mobile terminal 16b. For each of the mobile terminals 16a and 16b, an L2VLAN route is chosen to be utilized as an L3 communication tunnel based on the nearest base station 14. In the event that there is a failure in a link, there will be a L2VLAN switch. In this case, the logical L3 communication tunnel does not change. Failure recovery is possible only by switching the L2VLAN using an L2 switch. This improves the performance of a mobile communication system. Thus, this mesh-type network realizes a new mobile information management method and a communication method which are used for mobile communication in a mesh-type network.
