1. A method for managing tokens for digital rights management (DRM) in a terminal, the method comprising:
- controlling a token management module for acquiring at least one token from a rights issuer (RI); and
controlling the token management module for moving the token to a secure removable media (SRM) through a token installation request message,wherein the token can be shared by several terminals, andwherein the token installation request message includes;
a field for indicating a token issuer;
a field for indicating a service/programs for which the token can be used;
a field for indicating whether the token can be moved to another terminal;
a field for indicating whether the token can be shared among members of a specific domain;
a field for indicating that a token consumption must be reported and defining a uniform resource locator (URL) to which a tokenconsumptionreport message should be sent;
a field for indicating a latest token consumption time;
a field for indicating an earliest reporting time;
a field for indicating a latest reporting time; and
a field for indicating the number of tokens.

2. A method for managing tokens for digital rights management (DRM) in a terminal, the method comprising:
-
coupling the terminal to a secure removable media (SRM), the SRM including at least one token acquired from a rights issuer (RI) by another terminal; and controlling the terminal for acquiring the at least one token from the SRM, wherein the token can be shared by several terminals, wherein the acquiring of the at least one token comprises; sending a request for a token requested by the terminal to the SRM through a token consumption request message; and retrieving the requested token from the SRM through a token consumption response message, and wherein the token consumption response message includes; a field for indicating a token issuer; a field for indicating a service/programs for which the token can be used; a field for indicating whether the token can be moved to another terminal; a field for indicating whether the token can be shared among members of a specific domain; a field for indicating that a token consumption must be reported and defining a uniform resource locator (URL) to which a tokenconsumptionreport message should be sent; a field for indicating a latest token consumption time; a field for indicating an earliest reporting time; a field for indicating a latest reporting time; and a field for indicating the number of tokens. - View Dependent Claims (3, 4, 5, 6, 7)
