  • Patent number: 9559864
    Abstract: A wireless device includes a self-activation client that allows a user to activate a communication service for that wireless device and for one or more other wireless devices. The communication service may use a long-range type of wireless communication, such as 1×RTT CDMA, EV-DO, GSM, or IEEE 802.16 (WiMAX) communication. During the activation process, the wireless device communicates with a device management server using the long-range type of wireless communication but communicates with the one or more other wireless devices using a short-range type of wireless communication, such as IEEE 802.11 (WiFi), Bluetooth, or infrared communication. After the communication service has been activated, the wireless device may subsequently communicate with the device management server in order to manage the communication service for itself and/or for one or more other wireless devices (e.g., to receive updates or to make changes).

  • Patent number: 9554311
    Abstract: A method and corresponding system to help manage resources in a wireless communication system. When a first access network has allocated a resource for use in serving a UE and the UE has then transitioned from being served by the first access network to being served by a second access network, a determination may be made that (i) the UE has then moved into particular coverage of the second access network and (ii) the first access network does not have a coverage area that corresponds with that particular coverage area of the second access network. In response, the first access network may then release the resource that it had allocated for use in serving the UE. In a scenario where the first access is configured to normally release the resource upon expiration of a resource-release timer, the release in response to the determination may advantageously occur before the timer expires.

  • Patent number: 9544727
    Abstract: When a wireless communication device (WCD) is served by a first base station and not by a distant second base station, the WCD may initially be receiving strong pilot strength from the first base station and weak pilot strength from the second base station. Due to the WCD moving into a position where the first base station coverage is obstructed, however, the WCD may detect a quick drop in first base station pilot strength without a corresponding proportional increase in the second base station pilot strength, to the point that the second base station pilot signal is sufficiently stronger than first base station pilot signal that the WCD hands over to the second base station. In response to detecting that scenario, the WCD may report that the location of coverage of the second base station is an uncertain representation of the WCD's location, to help ensure reliable location-based service.

  • Patent number: 9544875
    Abstract: Disclosed is a method and system to manage paging channels in a wireless communication network. When the network encounters a situation where the network is to transmit an access response message in a coverage area to a mobile station, the network will determine whether the mobile station is in an access handoff state. If not, the network will transmit the message to the mobile station on a paging channel selected based on the mobile station's identifier. Otherwise, the network will transmit the message to the mobile station on both that paging channel and a default paging channel (e.g., primary channel) selected without consideration of the mobile station's identifier. This process can help avoid an access handoff failure. Further, a radio access network may opt to use the default paging channel in response to the wireless coverage area having a different number of paging channels than an adjacent coverage area.

  • Patent number: 9544829
    Abstract: A network node receives from a mobile terminal being served by a first coverage area a measurement report indicating signal level of a second coverage area detected by the mobile terminal. The network node then makes a determination, by considering PLMNs of the mobile terminal and of the coverage areas, of (i) whether the mobile node is a home mobile node of the first coverage area and (ii) whether the mobile node is a home mobile node of the second coverage area. Based on that determination, the network node then selects a handoff threshold. And based on the handoff threshold and the reported signal level, the network node decides whether to trigger handoff of the mobile terminal from the first coverage area to the second coverage area. The network node then triggers the handoff if the decision is to do so.

  • Patent number: 9532334
    Abstract: Disclosed is a system and method for multiple wireless communication devices (WCDs) to share a resource block in an orthogonal frequency division multiplexing communication system by assigning each WCD a different one of multiple different sub-segments of the resource block. A base station can allocate the shared resource block on to the WCDs, and use hash function applied to each WCD to assign a different one of the sub-segments to each WCD. Each of the WCDs can apply the same hash function to determine the same sub-segment assignment made by the base station. For downlink communications, the base station can transmit data to each WCD in the assigned sub-segment, and each WCD can recover its data from its assigned sub-segment. For uplink communications, each WCD can transmit its data to the base station in its assigned sub-segment, and the base station can recover each WCD's data from the assigned sub-segment.
