In one embodiment, a mobile communications system has a plurality of radio access network (RAN) nodes communicating wirelessly with a plurality of wireless user devices, a video server transmitting one or more packetized video streams to one or more of the wireless user devices, and a packet core routing packets of video data from the video server to the one or more wireless user devices via the RAN nodes. For each packetized video stream, the video server transmits in-band information related to the packetized video stream, such as relative screen size, relative video activity level, and minimum and maximum video quality levels, and each RAN node extracts and uses the in-band information to schedule transmission of the packets of video data to its one or more corresponding wireless user devices. The system can provide higher-quality video experience without wasting bandwidth on user devices that don't require much communication resources.

A method of operating a first cache device may include receiving, at the first cache device, a request to send a first asset to a second device; determining whether the first asset is stored at the first cache device; and when the determining determines that the first asset is not stored at the first cache device, obtaining, at the first cache device, the first asset, comparing, at the first cache device, a moving average of a marginal value of the first asset with respect to the first cache device and a characteristic marginal value of the first cache device, calculating a cost associated with the first asset, selectively storing the first asset at the first cache device based on the comparison, and sending the obtained first asset and the calculated cost to the second device.

Systems and methods are disclosed for pre-fetching assets from content providers to user equipment (UE). In one embodiment, the UE initiates a pre-fetch operation to download assets from content providers in advance of an end user requesting the assets. The UE accesses a resource profile for the pre-fetch operation that indicates the content providers that have assets for the UE to download in advance for local storage on the UE, and defines a percentage of UE resources allocated to each of the content providers for downloading the assets during the pre-fetch operation. The UE may then download the assets from the content providers based on the resource profile, and store the assets in a local memory.

Pre-fetching of assets to user equipment

Embodiments of the present invention provide a system, apparatus and method for address management in a distributed mobile core network. The apparatus includes a user equipment for managing multiple addresses for connecting at least one application client of the user equipment to a respective application server via at least one network. The user equipment includes a mobile address unit configured to manage a principal address, a local macro network (LMN) address, and a local area network (LAN) address. The principal address is used for data transmissions of a first type, the LMN address is used for data transmissions of a second type, and the LAN address is used for data transmission of a third type.

A method of sending hypertext transfer protocol (HTTP) adaptive streaming (HAS) content from a content source to a client over a transmission control protocol (TCP) connection between the content source and the client may include receiving a request for one or more first HAS data chunks from the client; sending the one or more first HAS data chunks to the client; generating idle delay values indicating an amount of delay in the TCP connection during an idle time period, the idle time period being a time period over which no HAS data chunks are being sent from the content source to the client; receiving a request for a second HAS data chunk from the client; setting the size of a starting TCP congestion window based on the idle delay values; and sending the second HAS chunk to the client using the starting TCP congestion window.

Systems and methods are disclosed for adjusting resource profiles which are used by user equipment (UE) to pre-fetch assets from content providers. In one embodiment, a recommender system receives a resource profile from a UE. The resource profile indicates content providers that have assets for the UE to download in advance during a pre-fetch operation. The resource profile also defines a percentage of UE resources allocated to each of the content providers for downloading the assets during the pre-fetch operation. The recommender system then adjusts the percentages of the UE resources in the resource profile for the end user to generate an updated resource profile for the end user, and transmits the updated resource profile to the UE for use in one or more subsequent pre-fetch operations.
