The invention discloses a modulator, a demodulator and a wireless communication system. The wireless communication system comprises a modulator and a demodulator. The modulator is suitable for generating a target linear frequency modulation signal, wherein the target linear frequency modulation signal is a signal of which the frequency is varied linearly over time, wherein the phase of the target linear frequency modulation signal is determined by an initial frequency and a frequency stepping of the target linear frequency modulation signal, and the frequency stepping is determined by the bandwidth of the target linear frequency modulation signal and the spreading factor of the target linear frequency modulation signal. The demodulator is suitable for demodulating the target linear frequency modulation signal. According to the scheme, power consumption can be reduced while long-distance signal transmission is realized.

Techniques for hybrid videoconferencing are described. A method of hybrid videoconferencing may comprise receiving, by a call routing service, a request to initiate a call with a provider from a user device, providing, by the call routing service, first endpoint data associated with a first connection between the user device and an agent device associated with the provider, establishing the first connection between the agent device and the user device via the call routing service, providing, by the call routing service, second endpoint data associated with a second connection between the user device and the agent device, and establishing, by a peer-to-peer (P2P) contact service, the second connection between the agent device and the user device.

An IP telephony system allows a user to register a telephony device that receives its native telephony service from a different telephony service provider as an extension telephone. The user can then place calls through the IP telephony system using the extension telephone. Such calls may or may not be established using the extension telephone's native telephony service provider.

A processing device receives a request from a client for a specific service. Responsive to determining that the specific service is not running, the processing device converts a previously instantiated generic service into the specific service. To perform the conversion, the processing device assigns the generic service from a service pool for the specific service and renames the generic service based on a name of the specific service. The processing device additionally queries a directory service for specific service logic associated with the specific service. The processing device receives at least one of the specific service logic or a reference to the specific service logic from the directory service, and updates the generic service to include at least one of the specific service logic or the reference to the specific service logic.

Aspects are directed toward use of data communications server(s) and a Platform as a Service (PaaS) interface to provide remote services for endpoint devices of a plurality disparate client entities. In one example, an apparatus includes a computing server to provide data communications for a plurality of endpoint devices respectively associated with a plurality of disparate client entities according to and responsive to client-specific sets of control data. The apparatus also includes a processing circuit configured to adjust routing of the communications by the computing server, in response to call event data generated by the computing server, by generating the client-specific sets of control data for each client entity according to a respective set of directives.

A wireless communication network delivers a video-conferencing service from a video-conferencing system to wireless User Equipment (UEs) over a wireless network core and a Radio Access Network (RAN). The wireless network core monitors performance of video-conferencing functions in the video-conferencing system and prioritizes the video-conferencing functions based on their performance. The wireless network core transfers a video-conferencing function list to the RAN that prioritizes the video-conferencing functions by their performance. The RAN wirelessly transfers the video-conferencing function list to the wireless UEs. The RAN wirelessly exchanges video-conference signaling between the wireless UEs and the wireless network core. The wireless network core exchanges the video-conference signaling between the RAN and the video-conferencing functions. Individual wireless UEs select their individual video-conferencing functions based on the video-conferencing function list that prioritizes the video-conferencing functions by their performance.

Systems and methods for improving quality of a call over network (CON) are provided. Modules may be distributed over the network at nodes. The modules monitor data quantity through the node, and data quality from one node to another. This fidelity and usage data is provided to a server where the data may be utilized to decide on how to route a call over network. The selected pathway may be decided based upon avoidance of “problem” legs where packets have historically been lost, or based upon the desire to load level data transmissions. A signal indicator for the signal quality of the networks “last mile” may be provided to the user. The last mile is the portion of the data pathway dependent upon the telephone service provider's infrastructure that cannot be rerouted around.
