ANSI 41 dialed number validation
First Claim
1. Apparatus for dialed number validation in an ANSI 41 cellular radio telecommunications system comprising:
- a first network element responsive to an ANSI 41 feature request from a second network element by sending a dialed number validation request to a third network element, the third network element responsive to the dialed number validation request by validating the dialed number and sending a dialed number validation return result to the first network element, the first network element responsive to a reception of the dialed number validation return result by sending an ANSI 41 feature request return result reflective of the dialed number return result to the second network element.

Abstract
A cellular system in accordance with the principles of the present invention permits one node, or network element, within a cellular system to request dialed number validation from another network element in the cellular system. The invoking and responding nodes may be any of the following: a mobile switching center, a home location register, a service control point, or a service node. Upon reaching a state in call processing where further dialed number analysis may be required, the invoking node will send an ANSI-41 compliant dialed number validation request message to the node performing validation. The validating node will determine whether the dialed number is allowed under the subscriber'"'"'s dialing plan. After making the determination, the validating node will return a message to the invoking node indicating whether the specified digits are allowed according to the subscriber'"'"'s dialing plan.
