Abstract: Information is communicated between access points to cause a recipient access point to invoke an action. In some aspects, a mapping is defined between: 1) sets of physical layer identifiers and/or associated time offsets; and 2) different types of information. The mapping information is provided to access points in a wireless communication system such that an access point can use this scheme to communicate specified types of information to another access point. Based on the mapping, an access point that receives a set of physical layer identifiers from another access point is able to determine the type of information being communicated. The recipient access point may then invoke a specific action based on the type of information that was communicated.

Abstract: A system for optimizing mobility robustness is operable by a network entity that detects handovers or connection failures by served access terminals. The network entity defines classifications based on mobility, route, past serving cell, or location information for the served access terminals and associates each of the handovers or connection failures with a related classification. A system for improving handover performance records a time for which an access terminal is served by the network entity before being served by a neighboring cell. A performance metric is determined based on the recorded time and a handover policy is optimized based on the performance metric.

Abstract: Uplink transmissions by an access terminal are used to communicate information from one access point to another access point. For example, a first access point that is serving an access terminal and wishes to communicate certain information to a second access point configures the access terminal to conduct an uplink transmission using a specified physical layer parameter. The specified physical layer parameter is different from the physical layer parameter normally used by the access terminal for uplink transmissions to the first access point. The second access point monitors for uplink transmissions that are based on the specified physical layer parameter. Detection of an uplink transmission (based on the specified physical layer parameter) by the second access point results in the information being conveyed to the second access point.

Abstract: Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon over an operating frequency of the macrocell base station, and the macrocell base station, and/or one or more network components, can identify the femto node based on one or more parameters reported by the device from receiving the beacon. The beacon can be transmitted at varying powers to ensure active hand-in triggering, mitigate interference and/or can be powered on and off for such purposes. In addition, a macrocell base station can regulate compressed mode periods during which a device can measure the femto node based on receiving information regarding device proximity to the femto node, or a device can generate proximity indication messages base on measuring the beacon signals, etc.

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.

Abstract: A timer parameter used for transitioning between radio protocol states is adapted based on a change of a handover parameter. For example, as a direct result of a change in a handover parameter such as time-to-trigger, offset, or hysteresis, an inactivity timer that is used for switching an access terminal from a connected state to an idle state may be adapted. As another example, as a direct result of a change in a handover parameter, a radio link failure (RLF) timer that is used for switching an access terminal to an RLF state may be adapted.

In some examples described in the present disclosure, a method is provided for updating a paging area identifier, which may include observing one or more parameters of signals received in a wireless network, updating a previously selected paging area identifier to a new paging area identifier based at least in part on the one or more parameters, and transmitting the new paging area identifier. In addition, example methods are provided for paging devices in a wireless network, which may include determining a paging area identifier related to a last known low power base station for a device, determining a plurality of low power base stations using the paging area identifier, and causing the plurality of low power base stations to transmit a paging signal for the device.
