Abstract: A method of obtaining communication party identity information in a mobile terminal is disclosed. According to the method, an attempt from a remote communication party to establish communication over a mobile telecommunications network is detected. First identity information about the remote communication party is determined from the detected attempt. A memory in the mobile terminal is searched for certain additional identity information associated with the first identity information. In the absence of such additional identity information, an additional identity information request is transmitted from the mobile terminal to a remote server using the mobile telecommunications network, said request including said first identity information as a search key. An additional identity information reply is received over the mobile telecommunications network. Additional identity information contained in the additional identity information reply is processed to render it available to a user of the mobile terminal.
