Title:
COMMUNICATION SYSTEM, COMMUNICATION TERMINAL, AND NETWORK
Document Type and Number:
WIPO Patent Application WO/2021/024948
Kind Code:
A1
Abstract:
The present invention provides technology that enables the robustness of a communication system to be improved. The communication system comprises a communication terminal, a first network constructed to be wirelessly communicatable with the communication terminal, and at least one second network constructed to be communicatable with the first network. When, while the communication terminal is connected to the first network and is connected to the at least one second network via the first network, the first network determines that the connection between the first network and the communication terminal be released (ST1401), the communication terminal or the first network indicates to the at least one second network that the connection with the communication terminal be released (ST1405).
