Methods, devices, and system related to wireless communications are disclosed. In one example aspect, a method for wireless communication includes receiving, by a first access node in a first type of communication network, a request from a wireless device to establish a voice session with an Internet Protocol Multimedia System (IMS); initiating, by the first access node, an IMS voice session establishment for the wireless device; configuring, by the first access node, a Quality of Service (QoS) for the IMS voice session using a Protocol Data Unit (PDU) session modification request; and determining, in part based on one or more capabilities of the wireless device, to refrain from triggering a fallback to a second type of communication network for the IMS voice session establishment.

Aspects of the disclosure relate to application mapping and alerting based on data dependencies in business and technology logic. In some embodiments, a computing platform may receive a request to map enterprise technology resources. Then, the computing platform may generate a business capability model. Next, the computing platform may cause a user computing device to display a graphical user interface comprising selectable graphical representations of applications associated with the enterprise technology resources. Then, the computing platform may receive a user input identifying an occurrence of a technology incident by selecting one of the graphical representations. In response to the selection, the computing platform may trace, using the generated business capability model, upstream or downstream impacts of the technology incident. Then, the computing platform may cause a visual representation of data dependencies indicating upstream or downstream impacts of the technology incident to be displayed on the user computing device.

This technology enables prioritization of Multiple Stream Reservation Protocol (“MSRP”) transmissions in Audio Video Bridging (“AVB”) virtual local area networks (“VLANs”). An AVB switch receives a status from listener devices, associates a state with each of the statuses indicating whether each listener device is active or in-active, and stores each state in a database. For each listener device, a queue of MSRP protocol data unit (“PDU”) packets exists to be transmitted to the listener device. The AVB switch searches the database for listener devices with an active state, searches the queue for each active listener device for packets associated with an active state, and transmits the packets associated with the active state to each active listener device. Subsequently, the AVB switch searches each listener device's queue for packets associated with an in-active state and transmits the packets associated with an in-active state to each listener device.

The present invention relates to communications methods, apparatus and systems for providing media micro-services in a scalable and efficient manner. In an exemplary method embodiment, a packet plane control service entity performs the following operations: (i) receives a request from a Signaling-Session Border Controller to implement one or more micro-services on a media packet stream, the request including information about the media packet stream including stream identification information; generates instructions for one or more entities under the control of the packet plane control service entity to implement the requested one or more micro-services on the media packet stream; and communicates the generated instructions to the one or more entities under the control of the packet plane control service entity for implementation on the media packet stream.

A meeting control method includes: displaying one or more meeting presentation portals in a shared content selection page of a meeting application; determining, in response to a trigger operation on the one or more meeting presentation portals, a meeting presentation portal triggered by the trigger operation as a target meeting presentation portal, and determining an application corresponding to the target meeting presentation portal as a target application; and sharing and projecting, in the meeting application, only a target interface content in the target application based on protocol parameters of the meeting application and the target application in response to receipt success information transmitted by the target application, the target interface content being content that the meeting application has a permission of sharing and projection.
