摘要:
A system and methodology that facilitates triggering device scanning and efficient femtocell detection in areas dominated by macro cells is provided. In particular, the system can includes a jamming component that generates a small and measured amount of interference to user equipment or user equipments (UEs) camping on nearby macro carriers. Moreover, the power utilized to introduce the interference can be enough to cause macro signal quality around the femtocell access point (AP) to fall below a scan trigger level. The UE(s) can detect the macro signal quality decline below the scan trigger level and scan other frequency bands, including the femtocell, on which to camp. Additionally, the system can perform femto pilot gating, such that the jamming component can scan the radio environment surrounding the femto AP during an off state, to determine information that facilitates jamming of a macro pilot.

Efficient utilization and management of integrated mobile base station carrier trees is provided herein. Such trees provide an organizational structure for allocating calls in a code division, tone division, time division and/or like mobile infrastructure. Calls can be allocated to portions of the carrier tree as a function of characteristic(s) associated with the call. Accordingly, like calls are grouped within the carrier tree with like calls. In addition, portions of the carrier tree can be re-allocated to different types of traffic to meet fluctuations in traffic demand. Further, calls can be re-packed from existing segments of the carrier tree to other segments to maintain calls having common characteristics in contiguous groups, and to maintain idle segments another contiguous group(s). Accordingly, the wireless carrier tree can be packed and managed more efficiently, providing greater throughput and reduced contention for resources.

A system and methodology that can utilize measurement data collected by a set of femto access points (FAPs), during a network listen procedure, to detect one or more areas with weak macro network coverage and/or high interference. Moreover, an automatic cell planning (ACP) component can be employed to analyze the measurement data and update a transmission parameter(s) associated with a macro access point. After the update is implemented, the ACP component can trigger another network listen procedure at the set of FAPs and receive new measurement data. The ACP component can evaluate the new measurement data to dynamically verify that the implementation of the update resulted in an improvement of macro network coverage and/or interference within the one or more areas.

System(s) and method(s) are provided for managing network capacity in a wireless network that serves various traffic flows with disparate quality of service requirements. Management can be based on multi-stage scheduling in frequency-time domain. A first scheduling stage can generate an allocation of radio resources that minimizes inter-cell interference amongst a plurality of base stations. Based on the first-stage allocation of radio resources, a second scheduling stage can compute flow capacity for a set of radio resources specific to a base station, and acquire guaranteed-bit-rate (GBR) and non-guaranteed GBR traffic flows. GBR traffic flows can be matched to computed flow capacity to generate an allocation of frequency-time resources. In second scheduling stage, GBR traffic flows can be scheduled based at least in part on allocated resources and priority queuing. Based on allocation(s) in first and second scheduling stages, a third scheduling stage can schedule non-GBR traffic flows based at least in part on fair scheduling.

Systems and techniques for motion adaptive wireless user equipment (UE) in a wireless network are disclosed. These techniques can leverage kinetic information to select a preferred radio (or radio technology) or adapt a reselection scanning interval. This can serve to improve the performance of a UE by reducing the amount of power expended in maintaining an adequate level of connectedness to the wireless network components in the face of UE movement. In a further aspect, kinetic power generators can be employed as a source of UE transit data. Kinetic fingerprints can be compared to UE transit data, e.g., that acquired from a kinetic generator of the UE, to facilitate selection of preferred radios and reselection intervals. In this aspect, radio selection schema and reselection scanning schema can effectively be selected with little to no drain on a UE power source.

A system and methodology that facilitates efficient utilization of bandwidth on a transmission link between a base station and a core mobility network, during content delivery is provided. Moreover, the system includes a data storage device, adjunct to, or integrated within, the base station for storing content locally. Typically, the data storage device is updated by downloading content from the core network at an optimal time. For example, content can be downloaded to the data storage device when the core network-to-base station link is idle, under utilized and/or has sufficient bandwidth for the download. On receiving a request for content from a user equipment (UE), the base station can directly deliver the content to the UE from the data storage device, over an air interface, when the requested content is locally available.

A system and methodology that facilitates efficiently and accurately defining operating parameters for a femto access point (FAP) is provided. In particular, during provisioning of the FAP, the system obtains operating parameters utilized by a nearby FAP expected to have a substantially similar radio environment as the provisioning FAP. Moreover, weighting is applied to the nearby FAP to determine which set of operating parameters to utilize at the provisioning FAP. Accordingly, pre-existing operating parameters, optimized by the nearby FAP are employed to augment initial network listen measurements performed at the provisioning FAP, and thus improve speed and accuracy of initial FAP parameter provisioning.

A system and methodology that resolves complex mobility handling issues in Long Term evolution (LTE) networks, overlaid with Universal Mobile Telecommunications System (UMTS) macro and UMTS femtocells that share a common UMTS Absolute Radio Frequency Number (UARFCN), is provided. Moreover, an LTE user equipment (UE) includes a femto identification component that differentiates between the UMTS macro and UMTS femtocells by employing Location Area Code (LAC) data. In an aspect, the femto identification component ensures that the LTE UE connects to the UMTS femtocell as soon as the LTE UE enters the UMTS femtocell coverage area, even when the LTE radio frequency (RF) signal is deemed sufficient for communication. Further, the femto identification component ensures that the LTE UE stays connected to the LTE network, as long as possible, while outside of the UMTS femtocell coverage area.

System(s), method(s), and device(s) that facilitate managing resources associated with communication devices are presented. A mobile device(s) at cell edge identifies its in-use resource blocks (RBs) to a neighbor base station, or in-use RBs of a neighbor base station to the serving base station. In the former instance, the neighbor base station sorts RBs in ascending order based on signal strengths respectively associated with the RBs and mobile devices; in the latter instance, the serving base station ranks RBs in ascending order based on signal strengths respectively associated with the RBs and neighbor base stations. RBs having weakest signal strength are reused first for mobile devices at cell edge. Base station establishes a direct wireless radio path with another base station facilitated by employing a sequence of subframes where all subframes but a specified subframe are blanked, and data is transmitted between base stations during the specified subframe.
