  • Patent number: 10439886
    Abstract: A system and method for dynamically (re)configuring a service network based on profile information obtained from a Big Data Analytics platform. Received dynamic situation profiles relative to network states, subscriber states, etc. may be compared against corresponding characteristic situation profiles. If there is a similarity, a dynamic design change action may be effectuated for changing configuration of at least a part of the service network, e.g., a service chaining mechanism, operating to service user data flows of the subscribers.

  • Patent number: 10440768
    Abstract: A first base station includes a controller configured to receive capability information from a user terminal for indicating whether a user terminal supports a first architecture using SCG bearer or an second architecture using a split bearer. The SCG bearer goes via both a serving gate way and the secondary base station without going via the first base station. The split bearer goes via both the serving gate way and the first base station and is split in a PDCP layer of the first base station. One split path of the split bearer goes via the second base station, and another split path of the split bearer goes via the first base station and not via the second base station. The controller configures either the SCG bearer or the split bearer without simultaneously configuring the bearers even if the user terminal indicates it supports both first and second architectures.

  • Patent number: 10433221
    Abstract: A base station according to one embodiment is configured to perform communication with a radio terminal and a wireless wide area network (WWAN) system. The base station comprises a controller configured to transmit first configuration information with which the radio terminal configures a measurement report in the radio terminal. The measurement report is a report of a measurement result about a signal transmitted by a wireless local area network (WLAN) system from an access point. The first configuration information includes a predetermined identifier associated with a group of access points to be measured by the radio terminal. The predetermined identifier is associated with an identifier of each of the access points in the group. The group is a group in which the radio terminal is capable of steering among access points without being dependent on a command from the base station.

  • Patent number: 10425983
    Abstract: A base station in a system supporting WWAN-WLAN aggregation communication in which a radio terminal performs communication using WWAN communication and WLAN communication simultaneously. The base station includes a controller configured to acquire capability information indicating a function of the radio terminal, wherein a first function and a second function are defined. The first function splits a bearer of the radio terminal in a PDCP layer of the WWAN communication, and uses the WWAN communication and the WLAN communication for radio communication of the bearer. The second function uses only the WLAN communication for the radio communication of the bearer without splitting the bearer going through the PDCP layer. The controller is configured to acquire capability information of the second function as information different from capability information of the first function.

  • Publication number: 20190261140
    Abstract: A user equipment supports MBMS (Multimedia Broadcast Multicast Service) transmission using SC-PTM (Single Cell Point-To-Multipoint). The user equipment receives an MBMS service from a base station via SC-MTCH (Single Cell Multicast Traffic Channel). The user equipment receives, from the base station, MAC (Medium Access Control) CE (Control Element) indicating a suspension of transmission of the MBMS service via the SC-MTCH. The user equipment determines that the transmission of the MBMS service via the SC-MTCH is suspended in response to the reception of the MAC CE.

  • Patent number: 10361769
    Abstract: A signal forwarding device forwards signals between a user equipment (UE) device and a base station using a partial decode and forward (PDF) signal forwarding scheme where an incoming signal is demodulated and forwarded to a destination as a forwarded signal without decoding the incoming signal. The signal forwarding device transmits, to the base station, channel information regarding the UE-SFD channel between the UE device and the signal forwarding device. A base station (BS) scheduler determines the coding rate to be used by the UE device at least partially based on the channel information. The base station transmits coding rate information indicative of the coding rate to the signal forwarding device. A signal forwarding device (SFD) scheduler schedules communication resources for use by the UE device at least partially based on the coding rate information.

  • Publication number: 20190223156
    Abstract: A first radio terminal transmits and receives a radio signal by using a limited frequency band limited to a bandwidth of a predetermined number of resource blocks. A second radio terminal transmits and receives a radio signal by using a frequency band wider than the limited frequency band. A base station transmits configuration information of SC-MTCH by SC-MCCH. The base station sets a first period to the first radio terminal and sets a second period shorter than the first period to the second radio terminal as an SC-MCCH change period in which the configuration information of the SC-MTCH can be changed. The base station receives an MBMS interest indication from the first radio terminal, the first radio terminal being in a connected mode, and determines whether or not to shift the first radio terminal to an idle mode based on the MBMS interest indication.
