    Abstract: A method is provided for use in a network that includes a plurality of user plane functions that perform processing of user plane traffic sessions from one or more mobile wireless user devices. The method includes periodically monitoring resource utilization of the plurality of user plane functions to estimate a resource utilization level of respective user plane functions. Based on the periodically monitoring, the method further includes storing for the respective user plane functions a resource utilization level indicator for each of the respective user plane functions according a resource utilization level of the respective user plane functions. User plane traffic sessions for a given tracking area are re-assigned (moved) among the plurality of user plane functions based on the resource utilization level indicators for the respective user plane functions to achieve a desired quality of experience for the user plane traffic sessions.

    Abstract: With a controller coupled to a first multicast domain and a second multicast domain having incompatible multicast profiles, source and group (S,G) state information may be extracted from a plurality of nodes of the first multicast domain and the second multicast domain, A first interdomain border node may be within the first multicast domain. A second interdomain border node may be defined within the second multicast domain. The (S,G) state information may be transmitted to the first interdomain border node and the second interdomain border node. The multicast traffic may be transmitted between the first multicast domain and the second multicast domain via the first interdomain border node and the second interdomain border node based at least in part on the (S,G) state information.

    Abstract: The present technology is directed to generating a common Border Gateway Protocol (BGP) attribute, for example, BGP-Slice Identifier (ID) for a specific network slice and stitching the network slice across one or more domains to realize end-to-end slicing. The present technology can generate BGP ID for a specific network slice spanning a plurality of domains and map domain-specific attributes associated with sub-slices of the specific network slice in different domains of the plurality of domains to the BGP ID. The present technology can further facilitate distribution of the mapping of the domain-specific attributes to the BGP ID across the plurality of domains for stitching the sub-slices together from the domain-specific attributes based on the BGP ID to stitch the specific network slice across the plurality of domains. Furthermore, the present technology can identify a configuration error in the mapping of the domain-specific attributes and the BGP ID and transmit a feedback informing the existence of the error for performing remedial measures.

    Abstract: A method for a seamless transfer of a secure multimedia conference session from one endpoint device to another without a need to rekey the session is provided. In this method, a first endpoint device connects a participant to a multimedia conference session to which at least one other participant is connected and based on detecting one or more second endpoint devices within a predetermined location proximity of the first endpoint device, determines whether to transfer the multimedia conference session to a target endpoint device. Based on determining that the session is to be transferred, the first endpoint device establishes a secure pairing connection directly with the target endpoint device and provides, via the secure pairing connection, information about the multimedia conference session based on which the multimedia conference session is transferred to the target endpoint device without rekeying the multimedia conference session.
