Abstract

Method, devices, and computer programs for routing a message to a first network server (MSC1) in a server pool (CNSP) of a mobile communication system are disclosed. The mobile communication system comprises a controller (BSC2) of an access network (AN) connectable to the first network server (MSC1) and at least one further network server (MSC2) in the server pool (CNSP), wherein service points are defined (S100) and one or more of the service points are allocated (S110) uniquely to each of the network servers (MSC1), MSC2) in the server pool (CNSP). At least one of the network servers (MSC1, MSC2) has allocated (S110) at least two of the service points. A temporary identity is assigned (S150) by the first network server (MSC1) to a mobile device (MS). The temporary identity includes a selected service point which is selected (S140) from the one or more service points allocated to the first network server (MSC1). The temporary identity is transmitted (S160) to the mobile device (MS) and a message (S170) from the mobile device (MS) to the first network server (MSC1) is routed (S200) to the first network, server (MSC1) by extracting the selected service point from the temporary identity received by the mobile device (MS) and applying a routing algorithm to the selected service point. The routing algorithm reveals the first network server (MSC1) from an analysis of the selected service point.
