Abstract: A system, apparatus, and method for performing terminal address translation, and more particularly for identifying addresses of mobile terminals in a mobile network in order to communicate messages with the mobile terminals. Messages are received from a service consumer at a pseudonymity proxy operable within the mobile network, where the message includes an information exchange message including a pseudonym locally identifying a target mobile terminal. The pseudonym is translated into an address of the target mobile terminal unknown to the service consumer. The information exchange message is forwarded from the pseudonymity proxy to the address of the target mobile terminal.

Abstract: A method for communicating a message directed to or concerning a user (in which case the message may be a core service request), from a source entity (11) in a source system to a target entity (17) in a target system, the user having a first user identifier known to the source entity (11), and a second user identifier used by the target entity (17) to identify the user in the target system, with the second user identifier not known to the source entity (11), the method including: a step (71 81 82 83) in which the source entity (11) encapsulates the message in a first message envelope containing an element (52) including the first user identifier and an element (53) containing a user identifier placeholder, and also a link (L12) relating the first user identifier and the user identifier placeholder.

Abstract: A method for communicating a message. such as a core service request, directed to or concerning a user, from a source entity (11) in a source system to a target entity (17) in a target system, which is typically different from the source system, the user having a first user identifier known to the source entity (11), but not necessarily used by the source entity to identify the user for communications in the source system, and a second user identifier used by the target entity (17) to identify the user in the target system, wherein the second user identifier is not known to the source entity (11), the method including: a step (71 81 82 83) in which the source entity (11) encapsulates the message in a first message envelope typically according to an XML-based protocol, the message envelope containing an element (52) including the first user identifier and an element (53) containing a user identifier placeholder, and also a link (L12) relating the first user identifier and the user identifier placeholder.
