1. A method of operating a cellular mobile telecommunications network having mobile radio network cells and a network register in which identifiers of mobile terminals and network-related user data of the terminals are stored, wherein
the network register is formed from a peer-to-peer network having a multiplicity of decentralized register nodes networked with one another and each associated with and responsible for a respective geographic region formed by one or more of the mobile radio network cells; hash tables held in the register nodes hold the identifiers of the terminals as hash values and the user data associated with these hash values; and the peer-to-peer network has at least
a first register node associated with and responsible for a first geographic region formed of one or more of the mobile radio network cells and at which a mobile terminal temporarily registers for communication via the telecommunications network, anda second register node permanently assigned to the terminal and associated with and responsible for a second geographic region formed of one or more of the mobile radio network cells,the method comprising the steps of:
holding in the second register node a hash table in which the identifier associated with the terminal is stored as a hash value determined by a predetermined hash function, the terminal directly registering at the first register node by transmitting the identifier when it is located in the first geographic region, the first register node determining network-related user data of the mobile terminal on registration, and determining the hash value from the identifier by the predetermined hash function, the first register node using the hash value to determine the second register node, and transmitting the network-related user data to the determined second register node, storing the network-related user data associated with the hash value in the hash table of the second register node, and when a system requests the current network-related user data of the terminal at a third register node by transmitting the identifier associated with the terminal, the third register node
determines the hash value of the identifier by means of the hash function,uses the determined hash value to determine the second register node, andrequests the network-related user data associated with the determined hash value in the hash table of the second register node and then transmits it back to the requesting system. |
