  • Publication number: 20180139143
    Abstract: A logical interface is used to facilitate the exchange of information between a first radio network and a second network. The logical interface is realized by utilizing the control plane of the core network architecture to transmit information from the first radio network to the second radio network. Once the information is received by the second radio network, the second radio network determines at least one threshold value, which is sent to a user equipment device in communication with the second radio network. Upon receiving the at least one threshold value, the user equipment device can make traffic routing decisions, based on the at least one threshold value and other network-related parameters.

  • Publication number: 20180084529
    Abstract: A cellular communication system and method for delivering information, e.g., data and/or control-signaling, to a user equipment (UE) from a neighboring node are disclosed. The cellular communication system includes a first node configured to transmit information in one or more Multicast Broadcast Single Frequency Network (MBSFN) subframes over a radio frequency (RF) link between the first node and the UE, while the UE is being served by a second node. The first node can use a network-defined, dedicated portion of the MBSFN subframe for this purpose. Instead of only allowing the second node to send data/signaling messages to the UE, the disclosed techniques allow neighboring nodes to also deliver information to the UE. In particular, the neighboring nodes can transmit data and/or control-signaling to the UE using MBSFN subframes in order to minimize signaling overhead and signaling delay.

  • Patent number: 9843972
    Abstract: In a cellular communication system, a coverage area configuration transition includes incrementally expanding a compensation service area to include at least a portion of an area covered by the energy saving service area. For example, the compensation service area can be expanded to cover a first cell edge of an energy saving service area, and any UE devices located within the first cell edge can be handed over to the compensation service area. After the UE devices in the first cell edge are handed over, the energy saving service area can be reduced such that a second cell edge is created. The process of handing over the additional UE devices to the compensation service area and reducing the energy saving service area can be repeated as many times as necessary to handover all of the UE devices being served by the energy saving service area.

  • Publication number: 20170251410
    Abstract: Where a user equipment (UE) device transfers communication from a first radio access network (RAN) device to a second RAN device, the first RAN device receives a traffic offload indicator indicating that resources being used for data traffic for the UE device through the first RAN device are released because the data traffic communication has been transferred to the second RAN device. The first RAN device provides assistance parameters to the UE device that are determined at least partially based on the information that the data traffic communication has been transferred to the second RAN device. The UE device uses the assistance parameters in determining when to transfer data traffic RAN between the first RAN device and the second RAN device.

  • Publication number: 20170223594
    Abstract: Systems and methods for facilitating the mitigation of interference in the uplink of a small cell caused by macrocell user equipment in the case where the macrocell cannot identify the interfering macrocell user equipment because the user equipment cannot detect and report the small cell's downlink due to the small cell's uplink/downlink coverage imbalance. In an embodiment, the small cell provides the macrocell with a notification of the interference, the configuration information about its Physical Random Access Channel (PRACH), and a plurality of unique preambles and transmission times for non-contention-based transmissions on the small cell's PRACH. The macrocell orders each of one or a plurality of macrocell user equipment to transmit one of the unique preambles on the small cell's PRACH. The small cell reports to the macrocell the detected preamble transmissions, which allows the macrocell to identify interfering user equipment and perform corrective actions.

  • Patent number: 9706450
    Abstract: A common group cell identifier is transmitted by adjacent base stations. Handover processing is minimized for mobile relays traveling along a predetermined path that traverses the adjacent base stations. A first base station along the path transmits a group cell identifier and a first single cell identifier within a first service area. An adjacent base station transmits the group cell identifier and a second single cell identifier within a second service area that at least partially overlaps the first service area. The mobile relay monitors the group cell identifier in certain situations and only performs a handover when the group cell identifier changes. As a result, no handovers are initiated as the mobile relay travels down the path since the group cell identifier transmitted by the base stations along the path are the same.

  • Patent number: 9706369
    Abstract: Handovers of mobile wireless communications device from a source base station to a target base station are managed by transmitting handover information over a shared broadcast channel. The handover information required by a mobile wireless communication device for performing a handover may be transmitted within a Multicast Broadcast Multimedia Services (MBfviS) Single Frequency Network (M8SFN) subframe in some circumstances. In one example, the handover information includes Uplink (UL) allocation information, timing advance (TA) information, and a Cell Radio Network Temporary Identifier (C-RNTI), The synchronization between base stations of the MBMS system allows for the elimination of some messaging required in conventional systems for synchronization between the mobile wireless communication service and a target base station. As a result the time for performing a handover is reduced.
