Methods and systems for wireless number portability without WNP query

A switching component of a wireless communications network, the switching component comprising:

• means for receiving an incoming call to a called number;
• means for obtaining profile information associated with the called number, the profile information including a location routing number, wherein the profile information includes the location routing number in a forward-to field, and wherein the profile information includes a call type indicating that the forward-to field includes location routing information for a ported number;
• and
• means for determining whether the called number is a ported number based on the location routing number of the profile information.

A system for implementing wireless number portability in a wireless communications network, the system comprising:

• an originating switching component operatively coupled with the network to receive an incoming call to a called number;
• and
• a home location register operatively coupled with the originating switching component and storing profile information associated with the called number, the profile information including a location routing number associated with the called number, wherein the profile information includes the location routing number in a forward-to field, and wherein the profile information includes a call type indicating that the forward-to field includes location routing information for a ported number;
• wherein the originating switching component is operative to obtain the profile information associated with the called number from the home location register and to determine whether the called number is a ported number based on the profile information;
• and
• wherein the originating switching component routes the incoming call to the receipt switching component according to the location routing number.

A method for implementing number portability at an originating switching component of a wireless communications network, the method comprising:

• an originating switching component receiving an incoming call to a called number;
• the originating switching component obtaining profile information associated with the called number, the profile information including a location routing number;
• the originating switching component determining whether the called number is a ported number based on the profile information;
• and
• the originating switching component routing the incoming call to a receipt switching component according to the location routing number of the profile information;
• wherein the originating switching component determines whether the called number is a ported number and routes the incoming call without a number portability database query.
