Abstract: The present disclosure relates to the field of mobile communication, and in particular to a mobile terminal communication control method, a control device and a mobile communication system, so as to provide a communication solution in a double connection mode in the case that a radio link failure occurs between a mobile terminal and a macrocell or between a mobile terminal and a small cell. The mobile terminal communication control method includes determining, by a macrocell connected to a mobile terminal, that a radio link failure occurs between the mobile terminal and a small cell connected to the mobile terminal; controlling, by the macrocell, the mobile terminal to reaccess the small cell, or controlling, by the macrocell, the mobile terminal to access randomly a small cell, or cancelling the small cell by the macrocell. The method provides a communication solution in a double connection mode in the case that a radio link failure occurs between a mobile terminal and a macrocell.

Abstract: The present disclosure provides mobile terminal communication control methods, devices and related equipment. An MBS receives from a mobile terminal a RLF message indicative of a RLF occurring at the mobile terminal for an SBS, and transmits to the mobile terminal a first deactivation instruction message for instructing the mobile terminal to be deactivated for the SBS. According to the present disclosure, it is able to effectively control the communication of the mobile terminal in a dual-connection mode when the RLF occurs at the mobile terminal for the SBS.
