    Abstract: When a UE is served by a first RAN and engages in signaling via the first RAN with a second RAN for the second RAN serve the UE with a call (e.g., in a circuit-switched fallback process), the second RAN will determine a speed of movement of the UE and will decide based on the speed of movement whether to provide the UE with a second-RAN traffic channel assignment in addition to providing the UE with an indication of second-RAN coverage in which the call will be served. For instance, if the UE is moving at a threshold high rate of speed, then the entity will provide the UE with a second-RAN traffic channel assignment so as to help expedite the start of the call and to help avoid an issue where the UE may move out of the second-RAN coverage in which the call is to be served.

The determination module determines whether the execution time is greater than a first predetermined time and the execution module can inform the function to the sensors or the deputy coordinator, and executes the function. A coordinator control method and a wireless sensing network communication system and method are further provided.

  • Patent number: 10194375
    Abstract: Network signaling loads are controlled in a wireless network by monitoring traffic patterns at an access point and determining that the access point is a high turnover access point. A high turnover access point is determined based on an average time devices spend in a coverage area of the access point being below a threshold level. Beacon and/or probe response messages are generated that identify the access point as a high turnover access point. In addition, a turnover activity value may be generated for the access point and included in the beacon and/or response messages. A mobile device may determine whether to authenticate and associate with the access point based on the turnover activity value.

  • Patent number: 10194359
    Abstract: The present invention is a method and system for station location based neighbor determination and handover probability estimation. A serving access point determines the location and movement measurements of a station (STA). Neighboring access points report coordinates of cell fringes of the neighboring access points. The STA sends a request for system information to the current access point along with current location of the STA. The current access point provides the system information, and the STA utilizes the system information to determine best handover candidate from among neighboring access points and an estimate of the time for handover.

  • Patent number: 10194379
    Abstract: During a communication technique, an access point provides a message that includes one or more public land mobile network identifiers of one or more cellular-telephone networks that are supported by the access point. Then, an electronic device, which received the message, provides a candidate list specifying one or more access points that support communication with a cellular telephone network to a radio node that is associated with this cellular-telephone network. By communicating with a wireless-local-area-network (WLAN) controller, the radio node validates the one or more access points, and selects a target access point based on performance feedback from the WLAN controller. Next, the radio node instructs the electronic device to associate with the target access point. Moreover, the radio node and the target access point establish a secure-communication pathway, which allows the radio node to communicate data to the electronic device via the access point using an LTE Wi-Fi aggregation protocol.

    Abstract: A method is described herein that is performed by a connectivity service platform in a communication network. The platform is enabled to communicate with a radio device via a wireless network connection of a first subscription of the radio device. The method comprises falling back to a second subscription, thereby enabling the connectivity service platform to communicate with the radio device via a wireless network connection of said second subscription of the radio device instead of the first subscription. The method also comprises receiving a request message from the radio device via the network connection of the first subscription. The method also comprises sending a reject message to the radio device, in response to the received request message and in view of the platform having fallen back to the second subscription. The reject message comprises a fall-back indication for instructing the radio device to fall back from the first subscription.

  • Patent number: 10187839
    Abstract: This disclosure provides an apparatus and a method for controlling a soft handover rate. A distribution of cell signal strengths that is received by user equipment is obtained through analysis of measurement reports of the user equipment, a mapping relationship between soft handover parameters and air interface quality is determined, and the soft handover parameters are adjusted according to the mapping relationship. Adjusting soft handover parameters of a cell according to signal quality of the cell can reduce a soft handover rate and increase a capacity on a premise that communication quality is maintained. Further, after the soft handover rate is adjusted according to the air interface quality, monitoring of the air interface quality, and by modifying specific cell handover parameters, communication quality of the user equipment that performs a soft handover is maintained, and a balance between increasing the system capacity and maintaining the communication quality is achieved.

    Abstract: A mobile station is configured to support handover from a source base station to a target base station. The mobile station receives signaling from the target base station that indicates Packet Data Convergence Protocol (PDCP) protocol data units which have been successfully received at the target base station. In response, the mobile station generates further PDCP protocol data units for missing PDCP service data units from corresponding PDCP service data units buffered at the mobile station. The generating comprises using a different header compression state from that which was used for the missing PDCP service data units and ciphering specific to a connection with the target base station. The mobile station transmits the further PDCP protocol data units to the target base station.
