A technique for managing call-routing numbers in a mobile communication network using a distributed switching system is provided. The switching system embodies a cluster configuration, wherein at least one cluster of the switching system comprises a plurality of cluster members, each of which is capable of routing an incoming call based on a call-routing number temporarily associated with the call. A defined series of call-routing numbers is distributed between the plurality of cluster members. The management technique makes use of a common data structure which defines an amount of assignments equal to the length of a given series of call-routing numbers, wherein each assignment uniquely associates a cluster member with one or more least significant digits of the numbers of the number series.

Technique for managing call-routing numbers for mobile communication networks

This invention relates to the field of Telecommunications, in specific to a distribution mechanism for distributing calls within a Mobile Switching Center Server Blade Cluster. In particular, a method and a corresponding distributor entity for providing scalability and redundancy in blade cluster comprising a plurality of server blades of a telecommunication system are disclosed. The method comprises the steps of receiving a message of a subscriber comprising a unique subscriber identifier determining by use of the unique subscriber identifier a first value and determining by said first value a first server blade of said blade cluster, Further, by use of the unique subscriber identifier a second value is determined and by use of said second value a second server blade of said blade cluster, whereby the first server blade is excluded from being determined.
