A method and apparatus for delivering network operator advertisements to a mobile terminal in association with providing content from a content delivery network (CDN) are disclosed. A network node resides within a wireless communication network supporting the mobile terminal. The network node receives a content request directed to locally-cached content from the CDN, and determines that the requested content includes or is associated with an advertisement placeholder. In response to this determination, the network node sends an advertisement ID request that includes a network operator ID to an external advertisement server. An advertisement ID is received from the advertisement server responsive to the advertisement ID request. The network node maps the advertisement ID to a network operator advertisement associated with the advertisement ID, and dynamically links the network operator advertisement to the requested content. The network node delivers the requested content, including the network operator advertisement, to the mobile terminal.
