An electronic device according to various embodiments may include: a communication circuit; a display; a memory; and at least one processor operably connected to the communication circuit, the display, and the memory. The at least one processor may be configured to control the electronic device to: identify a first network connection between the electronic device and a first external electronic device using the communication circuit. In response to the identification of the first network connection, the electronic device may identify a second external electronic device. In response to the identification of the second external electronic device, the at least one processor may display a UI for connecting the first external electronic device and the second external electronic device on the display. In response to an identification of an input on the UI, the at least electronic device may transmit, to the second external electronic device, information at least partially based on the first network connection and usable for establishing a second network connection between the first external electronic device and the second external electronic device.

A relay device for call processing according to an embodiment may include: a database; a protocol relay unit; a call processing unit for checking whether a sender and recipient of a call are subscribers stored in the database, on the basis of an income SIP signal through the protocol relay unit, and providing the income SIP signal to an external call routing server when the sender of the call is the subscriber and the recipient of the call is not the subscriber; and a packet processing unit for rearranging incoming call packets of the call according to the sequence of the call packets and adjusting transmission speed of the rearranged call packets according to the situation in which the call packets are incoming.

A streaming orchestrator may monitor the quality of video being delivered to a home or other building. If the streaming orchestrator determines that additional performance is needed, it may create an additional User Plane Gateway in the virtual “white box” environment residing in the customer premises. The streaming orchestrator may instruct gNodeBs to continue to route traffic back to the central core functions or to route traffic to local user plane gateways which transmit video streams to the Internet via localized high-speed connections.

A user equipment (UE) can determine when to send an initial request for a voice communication to an Internet Protocol (IP) Multimedia Subsystem (IMS) core of a telecommunication network. For instance, the UE can identify when a call setup instruction should be sent to the IMS to cause a communication channel to be established. The UE can determine whether the UE will experience a change to another radio frequency band or radio technology based on test data, and delay sending the call setup instruction for a time period during which the test data can be analyzed.

Systems and methods for delivering content to user equipment are described. The content may be delivered using Internet Protocol (IP) delivery, Quadrature Amplitude Modulation (QAM) delivery, or another delivery format. For example, the system may receive content including a plurality of segments. The system may use manifest data to identify each of the plurality of segments. The system may also use the manifest data to generate index data for the plurality of segments, and the index data may be delivered to user devices with the plurality of segments. In some aspects, the system may use location information (e.g., timestamps, such as program clock references) for one or more data packet of the one of the plurality of segments to generate location information for other data packets.

A system is presented that includes secure push-to-talk voice functionality. Using encryption, authentication, user filtering, and integration with new and existing LMR systems, a secure voice platform ensures malicious software, unauthorized access and brute force security attacks will not compromise the voice communications of the system. The VoIP system is engineered to ensure graceful system degradation in the event of maintenance activities, natural disasters and failure modes. The hardened VoIP system offers the functions a LMR trunking system while utilizing broadband connections. Private calls, group calls, Emergency Alarms with covert monitoring capability, scanning and priority scanning may be incorporated into the system. The system includes a VoIP-controller that serves as a trunking controller, manages available VoIP-based conference bridges, and assigns them as needed to the parties involved in each voice call. The system includes multiple fallback methods that may be prioritized based on pre-failure analytics.

A method for communication by an electronic device is provided. The method comprises determining establishment of a data channel during an ongoing call with another electronic device; determining at least one application displayed on the electronic device and the another electronic device over the data channel during the ongoing call; determining a disconnection of the ongoing call between the electronic device and the another electronic device; and storing (508) a state of the at least one application in a memory of the electronic device based on determining the disconnection of the ongoing call, wherein the stored state of the at least one application is used for execution of the at least one application during another call.

A mobile application gateway for connecting devices on a cellular network with individual networks, such as enterprise voice and data networks and/or residential networks. The effects of the present invention are far reaching in terms of transferring effective call control from the cellular network into the control of the individual network such as the enterprise, and enabling new business models for the purchase of cellular service from a public cellular carrier by an enterprise. The invention may consist of a primarily of core network and services components based on the IMS network architecture, and is backward compatible to support legacy systems in place in current telecom and data networks.
