The present invention relates to an apparatus and method of providing a content push service, a mobile terminal, and a method of operating a mobile terminal. According to an exemplary embodiment of the present invention, a user datagram protocol (UDP) port is set between the mobile terminal and a content push service providing server. In addition, the mobile terminal drives an application that receives the content push service through the set user datagram protocol (UDP) port, by the request of the content push service providing server. The mobile terminal receives the content push service from the content push service providing server through the driven application. Accordingly, it is not necessary to select a specific identifier for each of existing applications and recognize a specific identifier for each node of the mobile communication network.
