Abstract

A wireless access network receives Content Delivery Network (CDN) registration data transferred by a plurality of CDNs. The registration data associates individual wireless communication device identifiers for individual wireless communication devices with individual CDNs. The wireless access network receives CDN signaling from an external data system indicating one of the individual wireless communication device identifiers for an individual one of the wireless communication devices. In response, the wireless access network processes the individual wireless communication device identifier from the external system to identify an associated CDN. The wireless access network then transfers at least a portion of the CDN signaling for delivery to the identified CDN.

Claims

1. A method of operating a wireless communication network to control content delivery to a wireless communication device, the method comprising:

the wireless communication network associating (downstream Content Delivery Networks) dCDNs with dCDN Quality-of-Service (QoS) levels;

responsive to the wireless communication device registering with the dCDNs, the wireless communication network associating the dCDNs with an International Mobile Subscriber Identifier (IMSI) for the wireless communication device;

the wireless communication network receiving CDN signaling transferred by an upstream CDN (uCDN) that indicates the IMSI for the wireless communication device and responsively selecting one of the dCDNs based on the dCDN QoS levels for the dCDNs associated with the IMSI for the wireless communication device; and

the wireless communication network transferring the CDN signaling for delivery to the selected one of the dCDNs.

2. The method of claim 1 further comprising

the wireless communication network associating the dCDNs with CDN Interface (CDNI) capabilities;

and

the wireless communication network selecting the one of the dCDNs comprises the wireless communication network selecting the one of the dCDNs based on the dCDN QoS levels and the CDNI capabilities for the dCDNs associated with the IMSI for the wireless communication device.

3. The method of claim 1 further comprising

the wireless communication network associating the dCDNs with content inventories;

and

the wireless communication network selecting the one of the dCDNs comprises the wireless communication network selecting the one of the dCDNs based on the dCDN QoS levels and the content inventories for the dCDNs associated with the IMSI for the wireless communication device.

4. A method of operating a wireless communication network to control content delivery to a wireless communication device, the method comprising:

the wireless communication network associating (downstream Content Delivery Networks) dCDNs with dCDN Quality-of-Service (QoS) levels;

responsive to the wireless communication device registering with the dCDNs, the wireless communication network associating the dCDNs with an International Mobile Equipment Identifier (IMEI) for the wireless communication device;

the wireless communication network receiving CDN signaling transferred by an upstream CDN (uCDN) that indicates the IMEI for the wireless communication device and responsively selecting one of the dCDNs based on the dCDN QoS levels for the dCDNs associated with the IMEI for the wireless communication device; and

the wireless communication network transferring the CDN signaling for delivery to the selected one of the dCDNs.

5. The method of claim 4 further comprising

the wireless communication network associating the dCDNs with CDN Interface (CDNI) capabilities;

and

the wireless communication network selecting the one of the dCDNs comprises the wireless communication network selecting the one of the dCDNs based on the dCDN QoS levels and the CDNI capabilities for the dCDNs associated with the IMEI for the wireless communication device.

6. The method of claim 4 further comprising

the wireless communication network associating the dCDNs with content inventories;

and

the wireless communication network selecting the one of the dCDNs comprises the wireless communication network selecting the one of the dCDNs based on the dCDN QoS levels and the content inventories for the dCDNs associated with the IMEI for the wireless communication device.
