摘要:
The present disclosure provides systems and methods for dynamically signaling encoder capabilities of vocoders of corresponding communication nodes. In one embodiment, during a call between a first communication node and a second communication node, a control node (e.g., base station controller or mobile switching center) for the first communication node sends capability information for a voice encoder of a vocoder of the first communication node to a control node for the second communication node. As a result, the second communication node is enabled to select and request a preferred encoder mode for the voice encoder of the vocoder of the first communication node based on the capabilities of the voice encoder of the vocoder of the first communication node.

This disclosure describes systems, methods, and devices related to disconnecting Wi-Fi radios due to operation of collocated wireless technology on a same device. A device may identify a first beacon received from an access point (AP), the first beacon indicating a beacon interval and received using a Wi-Fi radio. The device may determine an expected time to receive a second beacon. The device may identify a first signal received from a non-Wi-Fi radio collocated with the Wi-Fi radio. The device may determine, based on the first signal, an indication of a transmission or a reception of a second signal by the second radio during a time which overlaps the beacon interval. The device may determine a failure to identify a second beacon during the beacon interval. The device may determine a counter and may determine, based on the counter, a connection status of the first radio with the AP.
摘要:
A terminal and a method are described herein for offering termination-side services to a user. In one embodiment, the terminal (e.g., cellular terminal, enterprise or residential wireline device, mobile device) is configured to provide one or more termination-side services (e.g., color ring back tone, voice mail, call diversion, hold before answer) to the user. The terminal is further configured to enable the user to directly setup and manage the one or more termination-side services without interacting with the telecommunication network.
摘要:
A system and method for selecting MPLS network transport entities between a first endpoint and a second endpoint are presented. Working and protection entities are selected from a set of available entities based upon minimizing the probability of simultaneous failure and/or minimizing a cost function base upon one or more metrics.
摘要:
A method is presented for supporting SNCP over a packet network connecting to two SDH sub-networks and transporting one or more SDH paths that are SNCP-protected in both SDH sub-networks. The packet network connects to each of two sub-network interconnection points by a working path and a protection path. The packet sub-network may provide the same type of path protection as an SDH sub-network using SNCP, while avoiding bandwidth duplication.
摘要:
The present invention provides a method for manufacturing polymeric nano-structures (nano-shells), wherein the nano-structures are hollow and respond to a temperature change by reversibly changing their volume, and the method comprises the steps of providing a polymer forming supramolecular structures when dispersed in a liquid environment, dispersing the polymer in a liquid environment to form the supramolecular structures and crosslinking the supramolecular structures, where the crosslinking occurs with the structures, whereby the nano-shells are obtained. The nano-structures manufactured according to the present invention are useful in sequestering, transporting, or scavenging hydrophobic or hydrophilic materials.

The invention provides a responsive polymeric system, comprising: a polymeric responsive component capable of undergoing a transition that results in a sharp increase in viscosity in response to a change in temperature at a predetermined body site; wherein the polymeric component comprises hydrophilic and hydrophobic segments covalently bound within the polymer component, by at least one chain extender or coupling agent, having at least 2 functional groups; wherein the hydrophilic and hydrophobic segments do not display Reverse Thermal Gelation behavior of their own at clinically relevant temperatures and; wherein the viscosity of the polymeric component increases by at least about 2 times upon exposure to a predetermined trigger.
摘要:
Ion mobility spectrometer. The spectrometer includes an enclosure for receiving a sample therewithin and an electron beam window admits an electron beam into the enclosure to ionize the sample in an ionization region. A shutter grid is spaced apart from the ionization region and means are provided for sample ion preconcentration upstream of the shutter grid. The ion preconcentration is effective to reduce space charge resulting in a lowered threshold detection level.
