Abstract: Briefly, in accordance with one or more embodiments, a method to implement an extended service request procedure for a circuit-switched fallback, comprises communicating with a packet-switched network, and initiating an extended service request procedure for a circuit-switched fallback to handle a voice call. If the voice call is terminated prior to completion of the extended service request procedure, the extended service request procedure may be aborted, and the user may remain in communication with the packet-switched network. Otherwise, the user completes the connection to the circuit-switched network and communicates with a circuit-switched network to handle the voice call.

Abstract: Systems and methods of enabling access for non-emergency voice calls are described. A UE operates in a network supporting voice services via a multitude of RATs. The UE attempts to access the network via a first RAT offering voice services and data services. If the UE does not receive a response from the network within a first time period, the UE re-attempts the access to the network via the first RAT. If the number of access attempts for which the UE does not receive a response is at least a threshold value, the UE refrains during a second time period from further access attempts via the first RAT for the purpose of receiving data services, and continues to attempt access via the first or second RAT for the purpose of receiving voice services.

Abstract: A central trajectory controller including a cell interface configured to establish signaling connections with one or more backhaul moving cells and to establish signaling connections with one or more outer moving cells, an input data repository configured to obtain input data related to a radio environment of the one or more outer moving cells and the one or more backhaul moving cells, and a trajectory processor configured to determine, based on the input data, first coarse trajectories for the one or more backhaul moving cells and second coarse trajectories for the one or more outer moving cells, the cell interface further configured to send the first coarse trajectories to the one or more backhaul moving cells and to send the second coarse trajectories to the one or more outer moving cells.
