Abstract

A technique for handling mobile terminating calls in a distributed switch is described. The switch includes at least one cluster wherein the at least one cluster comprises a plurality of cluster members. Each cluster member is associated with a set of roaming numbers and adapted to route a mobile terminating call to either a recipient subscriber served by the cluster member or to another cluster member which serves the recipient subscriber. The at least one cluster further comprises a first data structure having a content that is common to and accessible by all the cluster members of the cluster. The first data structure specifies the plurality of cluster members and the roaming number set associated with each cluster member.

Claims13

Dependent claims

A switch for call routing in a mobile communication network, the switch including a cluster, the cluster comprising:

a plurality of cluster members, each cluster member being arranged to terminate an incoming call to a recipient subscriber service by the cluster member or to route the incoming call to another cluster member, wherein a number is associated with each incoming call, the associated number comprising at least one of a Mobile Subscriber Router Number (MSRN) and a Handover Number (HON), each cluster member having a set of numbers associated therewith, each of the numbers of the set of numbes comprising at least one of an MSRN and HON, and incoming calls associated with a number from the set of numbers being terminated at the associated cluster member;
a component arranged to provide a first data structure common to and accessible by, all the cluster members, wherein the first data structure specifieds each of the cluster members and the number set associated with each of the cluster members;
a component arranged to receive an incoming call by one of the cluster members;
and
a component arranged to determine, by the receiving cluster member, the particular cluster member to terminate the incoming call by consulting the first data structure based on the number associated with the received call.

A call routing method for a mobile communication network comprising a switch including at least one cluster, the cluster comprising;

a plurality of cluster members, each cluster member being arranged to terminate an incoming call to another cluster member, wherein a number is associated with an incoming call to a recipient subscriber served by the cluster member or to route the incoming call to another cluster member, wherein a number is associated with an incoming call, the associated number comprising at least one of a Mobile Subscriber Routing Number (MSRN) and a Handover Number (HON), wherein each cluster member has a set of numbers associated therewith, each of the numbers of the set of numbers comprising at least one of an MSRN and HON, and an incoming call associated with a number from the set of numbers is to be terminated at the associated cluster member;
providing a first data structure common to and accessible by all the cluster members, wherein the first data structure specifies each of the cluster members and the number set associated with each of the cluster members;
receiving an incoming call by one of the cluster members;
and
determining, by the receiving cluster member, the particular cluster member that is to terminate the incoming call by consulting the first data structure based on the number associated with the received call.
