Telecommunication switching system having distributed dialing plan hierarchy
First Claim
1. A method for administering a dialing plan of a telecommunication switching system having a plurality of switching nodes, comprising the steps of:
- informing each switching node of blocks of telephone numbers that each switching node is to own;
arranging the switching nodes in hierarchical groups with a highest hierarchical group comprising only one switching node that owns all of the telephone numbers upon initialization;
requesting by each switching node in hierarchical groups other than the highest hierarchical group permission to own a subset of the blocks of a set of telephone numbers from the switching node in a higher hierarchical group and presently owning the set of the blocks of telephone numbers; and
giving permission by each switching node upon receiving a request from a switching node in a lower hierarchical group to own the subset of the set of blocks of telephone numbers owned by each owning switching node to the requesting switching node.

Abstract
A system for distributing a numbering plan to switching nodes which are organized in a dialing plan hierarchy and for allowing an individual switching node to redistribute blocks of numbers to other switching nodes upon requests from those switching nodes to own the requested blocks of numbers. Further, the dialing plan hierarchy is automatically established upon system initialization with each switching node determining its position in that hierarchy. In addition, a switching node that needs to use only one number of a block owned by another switching node can request permission from the other switching node to use that telephone number for a telephone connected to the switching node. Such a use is referred to as hosting the telephone number. Hosting allows a telephone connected to one switching node to have a telephone number owned by another switching node and eliminates the constraint of requiring every telephone connected to a switching node to use a number from the block of numbers own by that switching node.

-
informing each switching node of blocks of telephone numbers that each switching node is to own; arranging the switching nodes in hierarchical groups with a highest hierarchical group comprising only one switching node that owns all of the telephone numbers upon initialization; requesting by a first switching node in a hierarchical group other than the highest hierarchical group permission to own a subset a set of the blocks of telephone numbers from a second switching node in a higher hierarchical group and presently owning the set of the blocks of telephone numbers; and giving permission to the first switching node by the second switching node upon receiving the request from the first switching node. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An apparatus for administering a dialing plan of a telecommunication switching system having a plurality of switching nodes, comprising:
-
means for informing each switching node of blocks of telephone numbers to be owned by each switching node; the switching nodes arranged in hierarchical groups with a highest hierarchical group comprising only one switching node that owns all of the telephone numbers upon initialization; means in a first switching node in a hierarchical group other than the highest hierarchical group for requesting permission to own a subset of a set of the blocks of telephone numbers from a second switching node in a higher hierarchical group and presently owning the set of the blocks of telephone numbers; and means in the second switching node for giving permission to the first switching node upon receiving the request from the first switching node. - View Dependent Claims (18, 19, 20, 21)
