Abstract: A serving network receives a first message to select, and indicate to, a target network to prepare a connection to a mobile base station relay (MBSR) before a determination is made transitioning the MBSR to handover a connection from the serving network to the target network. The first message includes a first set of parameters essential to maintain service connectivity for several UEs connected to the serving network through the MBSR. The serving network sends, to the target network, a request that includes the first set of parameters to reserve sufficient resources to service the connection to the MBSR. The serving network receives a status report indicating a level of resources the target network is able to allocate in support of the connection of the MBSR. The serving network is one of a TN and an NTN and the target network is another one of the TN and the NTN.

Abstract: A mobile base station relay (MBSR) receives, from an MBSR operator, through a serving network, a first message enabling the MBSR to determine whether the MBSR has an imminent need to transition to a target network. The first message includes one or more conditions for the transition, and a first set of parameters essential to maintain service connectivity for several UEs connected to the serving network through the MBSR. The MBSR determines the conditions are satisfied and sends, to the serving network, a second message, including the first set of parameters, to select the target network and indicate to the target network to prepare a connection to the MBSR before a determination is made transitioning the MBSR to handover from the serving network to the target network. The serving network is either a TN or an NTN and the target network is another one of the TN and the NTN.

Abstract: A process for a mobile base station relay (MBSR) operator is provided. The process determines that a connection of an MBSR to a serving network has an imminent need to transition to a target network. The serving network is either a terrestrial network (TN) and a non-terrestrial network (NTN) and the target network is another one of the TN and the NTN. The process sends, to the serving network, a message to select the target network and to indicate to the target network to prepare a connection between the MBSR and the target network before a determination is made for the MBSR to handover from the serving network to the target network. The message includes a first set of one or more parameters essential to maintain service connectivity for several UEs that are connected to the serving network through the MBSR.
