QUALCOMM Incorporated - San Diego CA

International Classification:

G06F 15/16

US Classification:

709217, 709218, 709219, 709230, 709231, 709232, 709239, 707 10

Abstract:

A communication transaction or use case is broken down into constituent parts, one of which can be provided, at the direction of a master service node, from the master service node or primary service path and the other of which can be provided from a support service node or secondary service path that the client station might happen to be able to communicate with. For instance, the base layer of a multimedia stream might be provided from the master node, but if its bandwidth becomes full, an enhancement layer of the stream can be provided by the support node, as directed by the master node.

International Classification:

H04Q 1/00

US Classification:

455411, 455410

Abstract:

A system device and method are provided which determine authorization for access to one or more services grouped together as a package of services without direct intervention of a wireless network provider or wired network access provider. This offers business proprietors, contractors for telecommunication services, service resellers, OEMs and service providers the ability to authorize users, particularly users of mobile communication terminals, hereafter referred to as the “Owner,” access to package services. In this way a large package of features and applications can be available to a mobile device, but access to those features and applications can be controlled by the Owner thus providing the Owner with control over expenses related to accessing those features and applications. It also provides the Owner the ability to secure and prevent unauthorized access to features and applications which could allow an unauthorized user access to sensitive data and equipment.

Abstract:

Embodiments describe a system and/or method for multiple party digital signatures. According to a first aspect a method comprises establishing a first validity range for a first key, establishing a first validity range for at least a second key, and determining if the validity range of the first key overlaps the first validity range of the at least a second key. A certificate is signed with the first validity range of the first key and the first validity range of the at least a second key if the validity ranges overlap. According to another embodiment, signage of the certificate is refused if the first validity range of the first key does not overlap with the first validity range of the at least a second key.

International Classification:

H03M013/00

US Classification:

714/758000

Abstract:

A broadcast multimedia data stream is partitioned into two or more parts based on importance, e.g., a first part might represent more significant bits in groups of bits representing pixel colors in a video frame, while a second part might represent the less significant bits in the groups. The more important part of the stream is error correction coded at a lower rate or using a more powerful coding technique (i.e., with more error correction coding) than is the less important part of the stream.

Abstract:

A multimedia data stream is partitioned into two or more parts based on importance, e.g., a first part might represent more significant bits in groups of bits representing pixel colors in a video frame, while a second part might represent the less significant bits in the groups. The more important part of the stream is amplified more than the less important part of the stream.
