Abstract:
Firstly, the invention concerns a method for access control in a femto cell, comprising: assigning at least one femto cell to correspond to a first identifier that identifies valid access to said femto cell; storing a list comprising at least one second identifier and at least one first identifier, wherein a second identifier corresponds to an AT and said list indicates valid first identifier and second identifier pairs; receiving, at a femto cell, a request from an AT for access (1030); sending, by the femto cell, the first identifier to at least one access control component (1035); determining, from said list, whether a second identifier for said AT corresponds to a valid first identifier for a said femto cell (1040); and granting access to said AT at said femto cell in response to said request if said AT is identified. Secondly, the invention concerns a method for paging in femto cells.
Abstract:
A method, comprising: receiving a unique identifier in an uplink message related to an access point; inserting the unique identifier in an application layer downlink message to facilitate determining the access point related to the uplink message; transmitting the application layer downlink message to a network component; receiving a handover request message from the network component related to the access point and a target access point; inserting a unique identifier related to the target access point in the handover request message; and forwarding the handover request message to the network component or one or more disparate network components and a corresponding apparatus.

Secondly, the invention concerns a method for paging in femto cells.
Abstract:
An access terminal may switch to a different mode of wireless network selection as a result of manual selection of a wireless cell set (e.g., a closed subscriber group) associated with one or more wireless cells. For example, if the user of an access terminal selects a closed subscriber group in a wireless network that is different than the current wireless network, the access terminal may enter a manual mode of wireless network selection, select the wireless network corresponding to the closed subscriber group, and register on a closed subscriber group cell in the selected wireless network. In addition, an access terminal may automatically switch to a different mode of wireless network selection (e.g., the prior mode) upon losing coverage of a wireless cell set. An access terminal may also automatically select a cell of a wireless cell set if the access terminal returns to a cell of the cell set within a defined period of time after losing coverage of the cell set. Furthermore, an access terminal may return to a prior wireless network upon losing coverage of a wireless cell set.
Abstract:
Systems and methodologies are described that facilitate multiplexing communications from multiple downstream access points to one or more mobility management entities (MME). In particular, a concentrator component is provided that can establish a single transport layer connection with an MME along with multiple application layer connections over the single transport layer connection for each of multiple downstream access points and/or related mobile devices. The downstream access points and/or mobile devices can provide identifiers, such as tracking identifiers, to the concentrator component, which can utilize the identifiers to track communications with the MME. In this regard, the MME can send paging messages, and the concentrator component can determine downstream access points related to the paging messages based on a stored association with a tracking identifier in the paging message.

Abstract:
Local IP access paging schemes facilitate paging of an access terminal when packets destined for the access terminal are received via local IP access. In some implementations, a local entity acquires information that enables local paging of the access terminal by sniffing messages passing through the local entity. In some implementations, a local entity sends a packet or message to cause the core network to page an access terminal when a local IP access packet destined for the access terminal arrives at the local entity.
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.
