Abstract: The present disclosure relates to a network management system node for re-configuring a set of data network nodes in a data network in response to a change management request requesting a creation of a network service to be performed in the data network. The network management system node is characterized in that it includes a processing unit configured to store each change of network service information in created, added and/or updated data network nodes in the resulting set of data network nodes established by the re-configuration of the set of data network nodes based on the change management request requesting the creation of the network service as a change-set of network service information, and associate the change-set of network service information with a network service instance indicating the moment of the creation of the network service.

Abstract: A network hub interconnects a public access cellular telephone network transceiving signals according to a SS7 protocol with a wireless office environment transceiving signals according to a TCP/fP protocol. The wireless office environment comprises a TCP/IP network interconnecting a plurality of private wireless networks. A processor within the hub converts received signals between being carried by the SS7 and TCP/IP protocols. The conversions are assisted by a translation table including active mobile identification numbers and IP addresses within the wireless office environment and a second table listing all signal point codes for nodes within the public access cellular telephone network.

Abstract: A call routing number for a mobile station operating in a wireless telecommunication system is obtained by first requesting a temporary routing number for use in routing a call to the mobile station. Provided in response to the request is a routing number that had already been assigned to the mobile station when the request was received.
