  • Patent number: 9609555
    Abstract: According to some wireless network standards the size of a neighbor cell list is restricted to a maximum size. The limited size of a neighbor cell list may not reflect the realities of a wireless network deployment, especially for deployments including numerous femto cells clustered in close proximity. Accordingly, as the concentration of macro cells and/or femto cells in an area increases, there lies a challenge to identify and communicate neighbor lists to user devices that reflect the arrangement of a particular portion of the deployment and the needs of the user devices. Various systems, methods and apparatus described herein are configured to provide a user device or a group of user devices a neighbor cell list that includes neighbor cell identifiers chosen from a candidate list.

  • Patent number: 9521584
    Abstract: Traffic streams through mesh points in a mesh network are managed. Data arriving at the mesh point are aggregated in packet queues. The packet queues segregate arriving data by the data's Quality of Service (QoS) requirement. An appropriate communication channel is selected. The communication channel is accessed through a contention access schema. An M-Request-To-Send (MRTS) message is sent to potential receiving mesh points with receiving mesh points responding with an M-Clear-to-Send (MCTS) message. Data from the packet queues is transmitted to the next mesh point. A mesh point power save mode allows battery operated mesh points to sleep preserving power.

  • Patent number: 9491722
    Abstract: Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a minimum coupling loss from a transmitting node to a receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may autonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference. Transmit power may be defined based on channel quality. Transmit power may be defined based on a signal-to-noise ratio at an access terminal. The transmit power of neighboring access nodes also may be controlled by inter-access node signaling.

  • Patent number: 9445356
    Abstract: Providing for distributed access point management for access to a mobile network is described herein. By way of example, an interface application maintained at a Femto cell base station (BS) can facilitate initial power up and/or acquisition for a Femto user terminal (UT). Upon start-up, a bootstrap process is utilized by the Femto cell to provision the UT with an SDL establishing at least one BS as high priority within a particular geographic area (GEO). Thus, when the Femto UT is within the GEO, the UT is more likely to acquire, camp on and/or handoff to the preferred BS. When outside the GEO, a serving access point can provision the Femto UT OTA with a custom SDL suited to another GEO having a different high priority access point. By implementing access point management at distributed access points, expensive network equipment can be mitigated or avoided.

  • Patent number: 9432805
    Abstract: One or more mobile devices make measurements while moving along a path. Each measurement may comprise a specific group of identifiers of wireless transmitters, and strengths of corresponding wireless signals. A set of measurements are made in a sequence along a path, and the subsets of the measurements are identified for satisfying a test on a value of a measure of similarity of measurements included in the subset. A new place of relevance is identified, by comparing the just-described subsets of the measurements with similar subsets of additional measurements (e.g. by clustering). Alternatively, a known place of relevance (e.g. having a label) is identified, by comparing the just-described subsets of the measurements with pre-computed model of measurements. Also, the just-described subsets of the measurements may be compared with corresponding subsets of measurements of another path, e.g. to identify common portions therein.

  • Patent number: 9386431
    Abstract: Mobile user equipment (MUE) can be enabled to search for and camp on a preferred node, such as a home base node (HBN), in a battery-efficient manner even when currently camped on another node, such as a macro base node (MBN). When the MBN provides good channel quality, slow rate background intra- and inter-frequency searches can discover the preferred HBN that would otherwise not be discovered or would consume excessive power with continual searching. When channel quality is fair, slow rate background inter-frequency searches can result in timely switching to the preferred HBN. Location hints that indicate proximity of the preferred HBN can be used to trigger slow rate background searches. Neighboring cell searching of neighbor cell listing (NCL) when in channel quality is fair or poor are maintained to prepare for call reselections to available node.

  • Patent number: 9386541
    Abstract: Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a total received signal strength from transmitting nodes at the receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may autonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference and perform a self-calibration process.
