Document Type and Number:
Japanese Patent JP7028583
Kind Code:
B2
Abstract:
To provide a LTE communication system which makes communication of some terminals, belonging to a disconnected base station device, available even when communication connection between the base station device and a core network is disconnected.SOLUTION: A LTE communication system includes a base station device communicating in accordance with the LTE communication system. The base station device detects abnormality of communication of the base station device and the core network, and when abnormality is detected, transmits connection information for communication connecting, again, a terminal communication connected between the base station device and the base station device to the terminal, disconnects communication connection of the base station device and the terminal to which the connection information is transmitted, receives a connection request for communication connecting the base station device and the terminal again, re-establishes communication connection of the base station device and the terminal on the basis of the connection request, receives call control information for use in call connection of the terminal re-established communication connection, and holds the call control information in a recording device.SELECTED DRAWING: Figure 1
