Abstract: Conventionally, applications are updated to the current version and the previous version is removed, eliminating backward compatibility. The disclosed technology provides XR runtimes that can dynamically execute a runtime version due to the runtimes being executed as a collection of selectable data bundles. Thus, implementations can ship multiple versions of an XR runtime to allow old versions of the XR runtime to remain when updates occur. Implementations can maintain backward compatibility and allow old experiences to run in an application. Implementations can access metadata associated with an experience to determine what runtime version (or set of runtime versions) under which the experience can execute, and can dynamically run the latest runtime version that can support that experience. When multiple users in a group are joining an experience, implementations can select and run a common server-supported runtime and push any necessary data bundles for the experience to the client devices.

Abstract: Aspects of the subject disclosure may include, for example, a method in which a processing system authenticates a communication device roaming from a home network that does not support Voice over Long Term Evolution (VoLTE) roaming, and in which the processing system communicates with a packet gateway (PGW) of an evolved packet core (EPC) separate from the processing system, to facilitate communication between the communication device and a subsystem of the EPC; the subsystem emulates the home network to provide a VoLTE roaming service to the communication device. The communication device also engages in a session initiation protocol (SIP) with the subsystem to initiate a communication session with the subsystem; in accordance with the communication session, the subsystem provides the VoLTE roaming service to the communication device. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, obtaining roaming agreement data related to roaming agreements that are between a wireless provider and a respective one of a plurality of wireless roaming providers; obtaining, for each wireless subscriber of the wireless provider, respective roaming usage data, all of the respective roaming usage data comprising collective roaming usage data; training, based upon the collective roaming usage data, a set of one or more models, the one or more models comprising one or more statistical models, one or more machine learning models, or any combination thereof, the one or more models being trained with multiple iterations of feedback loops, and the training resulting in one or more trained models; estimating for each wireless subscriber, based upon the one or more trained models, respective projected location information for a future time, all of the respective projected location information comprising collective projected location information; obtaining,
