Abstract: The routing information is extracted from a received message at a border between a first network and a second network, and at least one invalid entry is added to first-network entries of the routing information which relate to a routing path of the message within the first network. The at least one invalid entry and the first-network entries are encrypted by using an own token at least for each of the first-network entries. As an alternative, a tokenized second-network entry extracted from the routing information and relating to the routing path of the message within the second network is decrypted, and its content is reversed. In both cases, the routing information is replaced by the processed routing information and the message is forwarded to the second network. This allows to preserve the order of routing entries and to hide the amount of switches that have been traversed in the home network.

Abstract: The present invention concerns a method for depositing a credit on an account associated to a terminal subscribed to a communication network, the method comprising the steps of: interacting (1) between the terminal and a network entity, wherein said interacting yields an indication of at least whether a credit is to be deposited on said account associated to said terminal, an amount of credit to be deposited and a source of the deposit, requesting (2) from said network entity to said source of the deposit, to deposit said amount of credit on an account associated to said terminal, wherein said requesting is based on the DIAMETER protocol.

Abstract: The present invention relates to a method and network device for processing a routing information in a packet data network. The routing information is extracted from a received message at a border between a first network and a second network, and at least one invalid entry is added to first-network entries of the routing information. The first-network entries relate to a routing path of the message within the first network. The at least one invalid entry and the first-network entries are encrypted by using an own token at least for each of the first-network entries. As an alternative, a tokenized second-network entry extracted from said routing information and relating to the routing path of the message within the second network is decrypted, and its content is reversed. In both cases, the routing information is replaced by the processed routing information and the message is forwarded to the second network.
