Wideband codec negotiation
The invention proposes several methods for codec handling. In specific, methods involving providing a supported codec list of a Call Control Server are described. A node receives information, whether a terminal supports a wideband codec, wherein the information is received in call set up signaling from the terminal of the subscriber. Furthermore, configuration information is retrieved, whether a Radio Access Node supports the wideband codec. Additionally, information is retrieved, whether a media gateway supports the wideband codec, wherein the information is either provided by the operator or retrieved from the media gateway (MGW1, MGW2, MGWx). The information is analyzed and in response to the analysis a supported codec list is provided. Furthermore, alternative embodiments and devices adapted for the methods are disclosed.
Systems, methods, and computer program products for selecting codecs to optimize resource utilization
Embodiments provide systems, methods, apparatus, and computer program products for selecting the codecs that each endpoint will use in a call in order to optimize the utilization of at least one internal resource of a network component. The network component receives a call invite from a first endpoint that identifies available codecs. The network component determines what codecs are available to the second endpoint and determines what codec pairing will have the least impact on at least one identified internal resource of the network component. The network component sends call set-up information to the first endpoint that identifies the selected codec or list of codecs for the first endpoint, and call set-up information to the second endpoint that identifies the selected codec or list of codecs for the second endpoint.
Techniques to rate-adjust data usage with a virtual private network
Techniques to rate-adjust data usage on mobile devices using a virtual private network are described. In one embodiment, an apparatus may include a processor circuit, and an application component operative on the processor circuit to present a link to third party data, receive a control directive to follow the link, and to request to access the third party data. The apparatus may also include a client virtual private network (VPN) component operative on the processor circuit to communicate with a server having a server VPN component, receive the request to access the third party data from the application component, determine whether the accessing is rate-adjusted, and connect to a source of the third party data via the server VPN component. Other embodiments are described and claimed.
Method and apparatus for mitigating network failures
A network may include a method that includes, for example, receiving a communication request responsive to a telephone number mapping query failure, where the communication request is initiated by an originating communication device requesting a communication session with a terminating communication device, foregoing initiating the communication session as a circuit-switched communication session responsive to determining that the originating communication device and the terminating communication device are enabled to use packet-switched communications, and instructing a second network node to initiate the communication session as a packet-switched communication session between the originating communication device and the terminating communication device responsive to the determination. Other embodiments are disclosed.
Method of processing a digital signal for transmission, a method of processing an optical data unit upon reception, and a network element for a telecommunications network
A method of processing a digital signal for transmission is provided comprising digital data frames, by compressing the digital data frames; and generating an optical data unit for transmission comprising multiple of the compressed digital data frames. The optical data unit is configured for transport by an Optical Transport Network, OTN.
GATEWAY APPARATUS AND COMMUNICATIONS SYSTEM
A gateway apparatus including a first inter-device interface configured to communicate with a monitoring apparatus; a second inter-device interface configured to communicate with a plurality of base station apparatuses that are subordinate; and a processor configured to generate second configuration information by a protocol conversion of converting first configuration information to a format compatible with the second inter-device interface, when the first configuration information is received from the monitoring apparatus through the first inter-device interface, the processor further configured to transmit the generated second configuration information to the plurality of base station apparatuses through the second inter-device interface.
Method to take mobile station preference for channel type into consideration when performing codec negotiation
Controlling establishment of a connection between an originating subscriber connected via an originating radio network to a communication network and a terminating subscriber connected via a terminating radio network to the communication network. The connection is established between originating payload node and terminating payload node employing a common coding scheme. Coding scheme negotiation comprises establishing, in originating control node (OCN), a list of supported coding schemes of originating subscriber, originating radio network and originating payload node. Determining, by the OCN, a radio channel property of the originating subscriber, oRCP, relaying the list and the radio channel property between the control nodes controlling the connection towards a terminating control node (TCN). Removing, by the control nodes, non-supported coding schemes from the list. Determining, by the TCN, common coding scheme(s) for the connection by selecting a remaining coding scheme considering the oRCP and a radio channel property of the terminating subscriber, tRCP.
Content-based client side video transcoding
Among other things, embodiments of the present disclosure improve the functionality of electronic messaging and imaging software and systems by automating the client-side transcoding of video data based on content. For example, an appropriate transcoding configuration can be selected for video data having complex motion or textures. Accordingly, video quality can be improve when complex motions or textures are present.

Tone frame detector for digital speech
Tone data embedded in a voice bit stream that includes frames of non-tone bits and frames of tone bits is detected and extracted by selecting a frame of bits, analyzing the selected frame of bits to determine whether it is a frame of tone bits, and, when it is a frame of tone bits, extracting tone data from it. Analyzing the selected frame includes comparing bits of the selected frame to sets of tone data to produce error criteria representative of differences between the selected frame and each of multiple sets of tone data. Based on the error criteria, a set of tone data that most closely corresponds to the bits of the selected frame is selected. When the error criteria corresponding to the selected set of tone data satisfies a set of thresholds, the selected frame is designated as a frame of tone bits.
