Faster Switching Of Citizens Broadband Radio Service (Cbrs) Profiles, Shivank Nayak, Sooraj Sasindran, Robert Greenwalt

Defensive Publications Series

Universal Integrated Circuit Card (UICC) and Embedded SIM (eSIM) offer the possibility of supporting multiple subscription profiles within the same card. Only one of these subscriptions can be active at a given time. However, a single active subscription may not work well for acquiring citizens broadband radio service (CBRS), which is highly localized, with a user likely to have subscribed to multiple providers, each with a corresponding subscription. As a result, supporting opportunistic CBRS data connectivity requires the modem to switch CBRS profiles by deactivating the active profile and activating a new profile. Such switching takes a noticeably long time. …

Lightweight Idempotent Operational Transform Inference In A Collaborative Editor, Owen Glofcheski

Defensive Publications Series

Per techniques of this disclosure, clients send opaque blobs of text to a server, rather than full operational transforms. The server uses the revision number received from the client to infer operational transforms by obtaining the shortest edit sequence between the received opaque text and revisions subsequent to the revision number. The techniques are particularly suitable for use in lightweight collaborative editors, such as note-taking software.

An idempotency issue potentially arises when not using full operational transforms in communications between client and server: duplicate requests can sometimes result in duplicate transforms on the server. Therefore, per the disclosed techniques, the …

Optimizing Signaling In 5g Non-Standalone Network Deployments Enabled With Presence Reporting Area, Somaraju Kaki, Anjaneyulu P.V.M.K.P

Defensive Publications Series

Techniques are provided herein for helping to address excessive Gx signaling. A Presence Reporting Area (PRA) feature coupled with Dual Connectivity New Radio (DCNR) / 5G Non-Standalone (NSA) network deployments enable Packet Data Gateways (PGWs) to offer Quality of Service (QoS) upgrade/downgrade of the respective bearer that was switched as part of a path update procedure based on the PRA Identifier (PRA-ID). This avoids upgrading/downgrading all the bearers associated with the Packet Data Network (PDN). Without these techniques, when the Master eNodeB (MeNB) triggers a path update for certain bearers, the Policy and Charging Rules Function (PCRF) would end up …

Data Saving Using Contextual Signals, Victor Carbune, Thierry Coppey

Defensive Publications Series

Mobile device applications and operating systems offer a data-saving option such that online content that is believed to be unchanged since last load is not reloaded. However, this sometimes leads to a situation where online content that has actually changed is not reloaded or that stale content is reloaded. The misdetection of fresh content as stale or vice-versa occurs due to the heuristics that are used by the data-saving algorithms of the application/ OS, due to misconfigured servers, etc.

This disclosure presents machine-learning techniques that determine if a web page or a portion thereof is to be reloaded. The techniques …

Authentication Using Sparse Modeling Of Fingerprint Images, Firas Sammoura, Matthew Robbins

Defensive Publications Series

Fingerprint sensors often have difficulty authenticating users if the user’s fingers are wet or moist, e.g., due to sweat. This disclosure presents robust techniques for fingerprint identification based on the K-SVD algorithm, which is a technique to represent images in a sparse manner. A K-SVD dictionary is created out of enrolled fingerprint images. A fingerprint that is to be authenticated is segmented into blocks, and each block is projected against the dictionary. A heat map of highest projection coefficients is formed, and overall match-score is calculated. The overall match-score is used to authenticate the fingerprint. The dictionary stores the essential …

Method To Dynamically Optimize Mimo Throughput Of Coupled Tunable Antennas, Vivek Bharambe, Matthew Slater

Defensive Publications Series

Many wireless communication standards (4G LTE, 5G NR, Wi-Fi, etc.) can leverage multiple antennas within a device through multiple-input multiple-output (MIMO) communication protocols. Antenna tuners are often used to tune the individual antennas for various transmission and reception characteristics. Traditional means of tuning the antennas, however, do not account for coupling between the antennas. Often, MIMO antennas are packaged within proximity of each other due to tight packaging constraints in modern electronic devices. In these types of coupled MIMO systems, maximum throughput is achieved when the coupling between the antennas is accounted for, even though a single antenna may not …
