Abstract
A wireless communication network serves data content to a wireless user device. An access wireless relay wirelessly receives a user request for the data content from the wireless user device. The access wireless relay wirelessly transfers the data content to the wireless user device when it stores the data content. When the access wireless relay does not store the data content, it transfers content requests having a Time-To-Live (TTL). Serving wireless relays receive the content requests during the TTL. The serving wireless relays transfer the data content to the access wireless relay if they store the data content. The serving wireless relays forward the content requests with the TTL when they do not store the data content. Terminating wireless relays receive the content requests after the TTL. The terminating wireless relays stop forwarding the content requests.
