Patent attributes
A method for conveying e-mail traffic between an e-mail server (108) and a mobile terminal (102) which has an e-mail address (122A) under the e-mail server and permanent terminal identity (122B) and a temporary identity (122D) in an access network (114). A connectivity function (600) is operationally coupled to the e-mail server (108) and the access network (114). The connectivity function (120) encrypts e-mail traffic to the mobile terminal and decrypt e-mail traffic from the mobile terminal, by using encryption information (122C). The mobile terminal generates (2-1) a service activation code which comprises an identifier (124D) of the mobile terminal, encryption information (122C) and checksum information. The service activation code is conveyed (2-3, 2-4) via a secure channel (2-3) to an authenticating terminal (100), from which the identifier (124D) of the mobile terminal and the encryption information (122C) are conveyed to the connectivity function (600).
