Abstract

A wireless communication network serves media content to a wireless communication device. The wireless communication network receives registration notices for the wireless communication device from Downstream Content Delivery Networks (dCDNs) when the wireless communication device registers with the dCDNs. The wireless communication network receives CDN signaling from an Upstream Content Delivery Network (uCDN) for one of the multiple dCDNs when the wireless communication device registers with the uCDN. The wireless communication network selects one of the dCDNs for the wireless communication device. The wireless communication network transfers the CDN signaling to the selected one of the dCDNs. The uCDN transfers media content to the dCDN and the dCDN transfers the media content to the wireless communication device.

the wireless communication network selecting one of the multiple dCDNs for the wireless communication device based on dCDN quality-of-service levels and transferring the CDN signaling from the uCDN for delivery to the selected one of the multiple dCDNs, wherein the uCDN transfers media content to the dCDN and the dCDN transfers the media content to the wireless communication device.

2. The method of claim 1 wherein the wireless communication network selecting the one of the multiple dCDNs based on the dCDN quality-of-service levels further comprises the wireless communication network selecting the one of the multiple dCDNs based on dCDN Content Delivery Network Interface (CDNI) capabilities.

3. The method of claim 1 wherein the wireless communication network receiving the registration notices for the wireless communication device from the multiple dCDNs comprises the wireless communication network wirelessly receiving at least some of the registration notices over a Local Area Network (LAN) that hosts at least some of the multiple dCDNs.

4. The method of claim 1 wherein:

the wireless communication network comprises the selected one of the multiple dCDNs; and

the selected one of the multiple dCDNs transferring the media content to the wireless communication device comprises the wireless communication network wirelessly transferring the media content to the wireless communication device.

5. The method of claim 1 wherein the selected one of the multiple dCDNs resides in the wireless communication device.

6. A wireless communication network to serve media content to a wireless communication device, the wireless communication network comprising:

transceiver circuitry configured to receive registration notices for the wireless communication device from multiple Downstream Content Delivery Networks (dCDNs) responsive to the wireless communication device registering with the multiple dCDNs;
