    摘要: Systems, methods, and devices can be utilized for policy control function (PCF) fallback during the set up of a session utilizing a 5th Generation (5G) core network. An example method includes receiving, from a session management function (SMF), a request for a policy corresponding to a session. The request includes a first policy identifier corresponding to a first policy control function (PCF). The example method further includes determining that the first PCF is unavailable, generating a modified request by replacing the first policy identifier with a second policy identifier in the request. The second policy identifier corresponds to a second PCF. The example method also includes transmitting, to the second PCF, the modified second request.

    摘要: An audio and/or video content delivery system (100) is deployed on top of a mobile network, and comprises plural cache servers (132) arranged using a layer-based hierarchical tree topology. A breakout function of aggregation nodes (130) of the mobile network enables routing to the cache servers (132) packets addressed to an anycast addressing associated with the cache servers (132), wherein each layer of the layer-based hierarchical tree topology is associated with an anycast addressing. Traffic steering is configured so that the breakout function in each layer routes traffic addressed to the anycast addressing associated with said layer to the cache server (132) of said layer as well as of any and all downstream layers, in order to ensure service continuity for delivering an audio and/or video content to a mobile terminal (150).
