  • Minimizing disruption to a voice call in a mobile network that includes different network segments having different capabilities for supporting voice calls
    Patent number: 11711732
    Abstract: A transition region can be defined for a first network segment that can provide wireless communication services using a first radio access technology (RAT) and a second RAT and that supports Internet protocol (IP) packet-based voice calls. The transition region can be defined based at least in part on a first coverage area of the first network segment and a second coverage area of a second network segment that does not support IP packet-based voice calls and does not support a first handoff mechanism based on the first RAT. A network node can be notified about an IP packet-based voice call involving a user equipment (UE) that is receiving service from the first network segment using a first RAT. Upon determining that the UE is located within the transition region, the network node can cause the UE to be switched to a second RAT for the IP packet-based voice call.

  • Dynamically adjusting the bandwidth of downlink transmissions based on a radio access technology used by a radio access network
    Patent number: 11653268
    Abstract: A core network can send first data transmissions to a radio access network (RAN) at a first data rate that is based at least in part on a first RAT policy associated with a first RAT used by the RAN for downlink transmissions to user equipment. The core network can obtain information indicating that the RAN is using a second RAT for the downlink transmissions to the user equipment. The core network can cause a RAT policy that is applied to the data transmissions from the core network to the RAN to be changed from the first RAT policy to a second RAT policy that is associated with the second RAT. The core network can send second data transmissions from the core network to the RAN at a second data rate that is based at least in part on the second RAT policy.
