US 2025/0097790 A1 · COMMUNICATION SYSTEM

Abstract

A communication system includes: a master base station operating as a master node of dual connectivity in which a communication terminal simultaneously connects to two base stations; and a secondary base station operating as a secondary node of the dual connectivity, and in a case where a second connection destination change process is required while executing a first connection destination change process in which a communication terminal changes a master node as a connection destination or a process in which a communication terminal changes a secondary node as a connection destination, the second connection destination change process being a process not falling under the first connection destination change process out of a process in which the master node is changed and a process in which the secondary node is changed, the second connection destination change process is started and the first connection destination change process is canceled.

Dependent claims

A communication system comprising:

a master base station that is a base station that operates as a master node of dual connectivity in which a communication terminal simultaneously connects to two base stations;
and
a secondary base station that is a base station that operates as a secondary node of the dual connectivity, wherein
in a case where a second connection destination change process is required while executing a first connection destination change process that is a process in which a communication terminal changes a master node as a connection destination or a process in which a communication terminal changes a secondary node as a connection destination, the second connection destination change process being a process not falling under the first connection destination change process out of a process in which the master node is changed and a process in which the secondary node is changed, the second connection destination change process is started and the first connection destination change process is canceled.

A communication system comprising:

a master base station that is a base station that operates as a master node of dual connectivity in which a communication terminal simultaneously connects to two base stations;
a secondary base station that is a base station that operates as a secondary node of the dual connectivity;
and
a communication terminal capable of simultaneously connecting to the master base station and the secondary base station, wherein
in a case where both a process in which the communication terminal changes a master node as a connection destination and a process in which the communication terminal changes a secondary node as a connection destination are required in a state where the communication terminal is connected to the master base station and the secondary base station,
in a case where the communication terminal selects a new master node as a connection destination prior to a new secondary node as a connection destination, the communication terminal selects the new secondary node as a connection destination on a basis of a selection result of the new master node as a connection destination and a predetermined condition, and in a case where the communication terminal selects a new secondary node as a connection destination prior to a new master node as a connection destination, the communication terminal selects the new master node as a connection destination on a basis of a selection result of the new secondary node as a connection destination and a predetermined condition.
