Abstract: The invention concerns a network element (4) for a telecommunication network (1) and a method of mapping address information according to a network numbering plan of the telecommunication network (1) to service access codes or network element addresses. The network element (4) receives address information according to the network numbering plan of the telecommunication network (1) and extracts a search key from the received address information. It provides a memory (42) with a data structure for representing, retrieving and modifying translation information mapping address information according to the network numbering plan to service access codes or network element addresses. The data structure has a tree structure with nodes and leaves operatively chained together wherein at least one of the nodes holds information nominating which part of the search key will be used to determine the branching of the respective node.

Abstract: The invention concerns a method of synchronizing a distributed system comprising a server (2) having a master data base (21) and a set of clients (31 to 35) having respective client data bases (41 to 45), as well as a server and a computer program product for executing this method. The client data bases (41 to 45) are incrementally updated from the master-data base (21) of the server (2). A trace of transaction (22) is maintained at the server (2) for recovery. The server (2) synchronizes the client data bases (41 to 45) in case of a failure by coordinated rollback transactions from the trace (22).

Abstract: The invention relates to a method for updating a remote data base with sets of data of a master data base system. The sets of data are forwarded to an intermediate data base, and the intermediate data base and the remote data base system are coupled by means of a synchronisation protocol. The protocol ensures, that the remote data base is reliably updated, wherein said master data base and said intermediate data base are logically independent data bases each part of a unique data base system controlled by a unique data base management, and also to master data base system therefore.

Abstract: The invention concerns a method of providing service data towards a set of two or more network elements (31 to 35) of a telecommunication network (1), as well as a service provisioning system (2) and a computer program product for executing this method. The service provisioning system (2) receives a plurality of change requests for said service data, the change request concerning one or more of the network elements of the telecommunication network (1). The service provisioning system (2) analyzes the dependencies of two or more received change requests and/or corresponding network elements specific update requests with respect to service data. Then, it aggregates independent change requests and/or update requests and transmits one or more concurrent update commands that force a parallel execution of the aggregated change requests and/or update requests to one or more network elements of the telecommunication network (1).
