摘要:
A method for adaptive Bluetooth low power wake up and discovery is provided whereby wake-up triggers are uploaded to Media Access Control (MAC) firmware. A data stream representing a trigger arrives as either an interpretable binary stream of instructions, or as a concatenation of events listed in a preset table. Various parameters allowing flexible wake-up triggering, such as Service Set Identifiers (SSIDs) to scan for probability likelihoods, are also uploaded. Both table-based and interpretable instructions are designed to ensure the security of the trigger by limiting the functionality of the trigger to only trigger-related events (e.g., scanning, pre-reserved memory). Both the table and the instruction set are designed in a minimalistic fashion to allow a slim and fast firmware-side implementation. Insignificant modifications to existing computer or Operating System (OS) architecture take advantage of the already existing MAC processor in many 802.11 interfaces, offering enormous flexibility.

A network can send cell reselection criteria to a mobile terminal. The mobile terminal measures or otherwise obtains radio condition measurements (such as received power, interference, mobile transmit power and the like) and/or geographical location measurements. The mobile can maintain a history of the cell selection criteria and/or measurements. The radio condition measurements are compared against historical data and/or cell reselection criteria and, based on the comparison; the mobile terminal can initiate cell reselection.

Processes to achieve low power discovery and wake-up in the presence of desired 802.11 coverage are disclosed. In one aspect, probabilistic scanning for 802.11 SSID triggers is provided. In another aspect, the 802.11 Access Point (AP) is equipped with a Bluetooth inquiring device, which initiates the wake-up process with a special inquiry access code (IAC). The special IAC can comprise the AP's 802.11 channel. Additional optional sensors (GPS, Gyroscope, odometer, etc) are provided such that probabilistic scanning reduces power consumption and improves the likelihood that an 802.11 channel scan will find a desired SSID. A Bluetooth inquiry allows a discovery process to either wake-up immediately, or ascertain the need for host wake-up by exchanging further information with the AP. Probabilistic scanning allows the use of sensors and historical or pre-loaded information to improve the probability that 802.11 scanning is not required on individual channels, further driving down power needs.

Methods, devices, processors and computer program products for mobile terminal-based Radio Resource Management (RRM) and network optimization. The mobile terminal measures or otherwise obtains radio condition measurements (such as received power, interference, mobile transmit power and the like) and/or geographical location measurements. The radio condition measurements and/or location measurements are compared against historical data and/or target Key Performance Indicators (KPI) and, based on the comparison, a determination can be made as to whether adjustment of RRM parameters is warranted. By providing for RRM management at the mobile terminal level, as opposed to a cell or Radio Network Controller (RNC) level, better granularity of management is realized in the overall radio network. Further, individual mobile terminals can better tailor their radio resource needs to meet their conditions of use and, as such, better overall service can be realized by the individual mobile terminals in the network.
摘要:
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.
摘要:
Aspects are disclosed for facilitating a hand-in to a femto cell. An identifier is assigned to a femto cell in which the identifier is based on a scrambling parameter and a timing parameter. A relationship between the identifier and the femto cell is then communicated. In another embodiment, a user equipment report is received, which includes attributes related to a signal broadcast by a femto cell. An identifier associated with the femto cell is ascertained from an attribute included in the report. The femto cell is then identified based on the identifier. In a further embodiment, a timing parameter is received, and a scrambling parameter is set. A signal including the scrambling parameter is then broadcast according to an offset related to the timing parameter. In yet another embodiment, a femto cell is detected during an active call. An identifier associated with the femto cell is then ascertained and reported.

A method of low power discovery (LPD) that extends the battery life of a portable Wi Fi device or portable media player (PMP) using IEEE 802.11 interface by ensuring that PMP host processor is only on when in designated 802.11 coverage or when needed by a user, by employing probabilistic channel scanning-comprising: A) bringing an AT host equipped with an 802.11 interface to an advanced configuration and power interface (ACPI) state S3 or equivalent sleep state, and prior to said device or media player going to sleep; and B) programming the 802.11 WLAN to wake up based on a predetermined trigger logic.
