This disclosure provides methods, components, devices and systems for multirate audio mixing. Some aspects more specifically relate to mixing audio streams with different sample rates. In some examples, an audio source device may convert audio streams with different sample rates to the frequency domain using a modified discrete cosine transform (MDCT), and the audio source device may mix the audio streams with different sample rates in the frequency domain. The audio source device may apply a pre-emphasis filter after mixing the audio streams in the frequency domain. An audio stream with a higher sample rate may be down-sampled by dropping frequency bins after converting the audio stream to the frequency domain. Additionally, or alternatively, an audio stream with a lower sample rate may be up-sampled by padding frequency bins of the frequency domain-converted audio stream.

The present disclosure relates to a system (108) and a method (600) for barring of SMS The system (108) includes an interface unit (210) to receive the SMS from a user equipment (UE) (102). The system (108) includes an identifier unit (212) to determine a Radio Access Technology (RAT) type of the received SMS. The system (108) includes a retrieval unit (214) to retrieve information pertaining to location of the UE from a Home Subscriber Server (HSS) (420) when the RAT type is determined as a Wireless Local Area Network (WLAN) type. The system (108) includes a comparison unit (216) to compare the retrieved information associated with the UE with a barred list to determine if the retrieved location is present in the barred list. The system (108) includes a transmittal unit (218) to transmit an error code in response to determination of presence of the location in the barred list.

A POTS alternative including an uninterruptible power supply (UPS), a router, a modbus converter for connecting the router to the UPS to monitor conditions of the UPS, a gateway for providing connections to one or more POTS-based customer premises equipment through the modbus converter to the router and directly to the router. The router includes a plurality of SIM cards, each SIM card for connecting to one cellular service provider among a plurality of cellular service providers. The router automatically connecting to a cellular service provider among the plurality of cellular service providers providing the strongest cellular signal and switching from the cellular service provider to a different cellular service providers when the different cellular service provider provides a stronger cellular signal when the cellular service provider no longer provides the strongest cellular signal.

The present disclosure relates to a system and method to facilitate a user device to establish simultaneous communication with plurality of emergency services. The system may include a network device including one or more processors that may cause the system to receive, from an Internet Protocol Multimedia Subsystem (IMS) server, a routed request derived based on an original request from the user device located at a pre-defined location. The network device may enable identification of a pre-defined contact information pertaining to the plurality of emergency services available at the pre-defined location of the user device. Based on the identified pre-defined contact information, the network device may invoke a call leg to initiate communication with the respective plurality of emergency services. Based on the invoked call leg, the IMS server may establish the simultaneous communication of the user device with the plurality of emergency services.

A first computing device may anchor a call between a remote computing device and a second, computing device tethered to the first computing device via. a local wireless tether connection. The first computing device may detect an occurrence of a. tethering termination event of the local wireless tether connection. The first computing device may, in response to detecting the occurrence of the tethering termination event, park the call at a call park server to enable the second computing device to resume the call without being tethered to the first computing device.

The present invention relates to a system (1) which enables a call to be blocked by detecting a change in the caller number, with the aim of preventing phone fraud.

The present invention relates to a system (1) which enables to generate call detail records related to voice and sms voice communications of the said persons upon foreigners -who are roaming- communicate with each other over voice and sms by using VoLTE, and ensures that the data traffic occurring in the network as a result of voice, sms, video-based agreements made with foreigners can be observed by the network.

Systems and methods are provided for voice call optimization. Methods include receiving a request to initiate a voice call from a wireless device configured to connect to a WLAN of a wireless gateway device. In response to receiving the request, the method includes determining an organizationally unique identifier (OUI) of the wireless gateway device and searching a database containing organizationally unique identifiers (OUIs) for the OUI of the wireless gateway device. The method further includes executing the voice call over a cellular network without using the wireless gateway device upon finding the OUI of the wireless gateway device in the database.

Embodiments include systems and methods for wireless device signaling a network regarding customized ringing signal (CRS) capability and use of such information by the network. Various embodiments may receiving from the network an INVITE message notifying the wireless device of an incoming call, determining whether the INVITE message indicates that the network provides CRS service if the wireless device supports a CRS function, and including an indication in a response to the INVITE that the wireless device supports the CRS function in response to determining that the INVITE message includes an alert information header field indicating that the network provides CRS service. Various embodiments include a network computing device receiving such information and performing negotiations for CRS service with the wireless device only if the wireless device indicates CRS functional capability.
