Methods and devices for facilitating access terminal registration with a registration server

Access terminals are adapted to communicate with registration servers to enable a registration server to perform timer-based registrations on behalf of an access terminal. The access terminal can cease performing such timer-based registrations as long as the registration server performs the registrations, and may power down until event data is available for transmission or reception. When a registration server performs timer-based registrations on behalf of an access terminal, the registration server can periodically communicate with a network entity to conduct the timer-based registrations for the access terminal. The network entity can receive a timer-based registration message from a registrations server for registering an access terminal.

Uniquely identifying target femtocell to facilitate femto-assisted active hand-in

Systems, methods, devices, and computer program products are described for supporting macrocell-to-femtocell hand-ins of active macro communications for mobile access terminals. An out-of-band (OOB) link is used to detect that an access terminal is in proximity of a femtocell (e.g., using an OOB radio integrated with the femtocell or in a common subnet with the femtocell). Having detected the access terminal in proximity to the femtocell, an OOB presence indication is communicated to a femto convergence system disposed in a core network in communication with the macro network to effectively pre-register the access terminal with the femto-convergence system. When the femto convergence system receives a handoff request from the macro network implicating the pre-registered access terminal, it is able to reliably determine the appropriate target femtocell to use for the hand-in according to the pre-registration, even where identification of the appropriate target femtocell would otherwise be unreliable.

The horizontal location uncertainty may be given by a radius of a circle centered at the latitude and longitude of the transmitter. The height uncertainty may be given by a deviation from the height of the transmitter. The transmitter may send the message to at least one receiver in a wireless network. The transmitter may be a base station that may broadcast the message to terminals within its coverage.

Message-based exchange of access point pilot signature indicators

An access point is identified based on a plurality of pilot signatures. Here, in addition to transmitting a pilot signal that is encoded (e.g., spread/scrambled) using a particular pilot signature, an access point transmits a message that includes at least one indication of at least one other pilot signature. For example, an access point may use one PN offset to generate a pilot signal and transmit a message that identifies at least one other PN offset. An access terminal that receives the pilot signal and the message may then generate a pilot report that identifies all of these pilot signatures. Upon receiving a handover message including this pilot-related information, a target network entity with knowledge of the pilot signatures assigned to that access point may then accurately identify the access point as a target for handover of the access terminal.

Thus, when a transition from the semi-connected state to the connected state occurs, the base station does not have to re-establish security parameters, nor re-establish logical traffic connections within the network for carrying control plane and user plane data for the UE. Context information for semi-connected state UEs may be shared between neighboring base stations or base stations within a context area. The techniques may be applied to LTE/LTE-A networks.

Message-based exchange of access point pilot signature indicators

An access point is identified based on a plurality of pilot signatures (pseudo-random noise, PN, spreading codes or scrambling codes). Here, in addition to transmitting a pilot signal that is encoded (e.g., spread/scrambled) using a particular pilot signature, an access point transmits a message that includes at least one indication of at least one other pilot signature (e.g. PN offset or PN phase). For example, an access point may use one PN offset to generate and transmit a pilot signal and transmit a different message that identifies (includes) at least another PN offset. An access terminal that receives the pilot signal and the message may then generate a pilot report that identifies all of these pilot signatures. Upon receiving a handover message including this pilot- related information, a target network entity with knowledge of the pilot signatures assigned to that access point may then accurately identify the access point as a target for handover of the access terminal.
