System and method for relaying an origination request from a home location register to a service specific service control point

1. A method for relaying an ORREQ (origination request) message from an MSC (mobile switching center) to a service specific SCP (service control point), comprising the steps of:

receiving at the MSC from a subscriber a service trigger indication to provide a particular service;

transmitting the ORREQ message having the service trigger indication included therein from the MSC to an HLR (home location register), wherein the HLR does not know the service specific SCP required to provide the particular service;

determining at the HLR the service specific SCP to provide the particular service associated with the service trigger indication of a plurality of available service specific SCPs responsive to at least one of the ORREQ message, the service trigger indication within the ORREQ message and a subscriber profile identified by the ORREQ message associated with the subscriber within the HLR, wherein the step of determining further comprises the steps of:

determining the service trigger and an identifier for the subscriber from the ORREQ;

accessing the subscriber profile responsive to the determined identifier to identify active services for the subscriber;

determining the service specific SCP to provide the particular service responsive to the service trigger and the active services for the subscriber;

determining an address of the specific SCP by accessing mapping logic; and

transmitting the ORREQ message from the HLR to the determined service specific SCP of the plurality of available service specific SCPs to enable the determined service specific SCP to provide the particular service to the MSC.

2. The method of claim 1 further including the step of transmitting an ORREQ reply response message from the service specific SCP to the MSC through the HLR.

3. The method of claim 1 , wherein the particular service comprises a WIN (wireless intelligent network) service provided by the service specific SCP.

4. The method of claim 1 , wherein the MSC comprises a pre-WIN (wireless intelligent network) MSC.

5. A method for relaying a call message requiring a particular service from an MSC (mobile switching center) to a service logic unit, comprising the steps of:

receiving at the MSC from a subscriber a service request to provide a particular service;

transmitting a call message including a service trigger indication requiring the particular service from the MSC to an HLR (home location register), wherein the HLR does not know the service logic unit required to provide the particular service;

determining at the HLR the service logic unit to provide the particular service associated with the service trigger indication of a plurality of available service logic units responsive to at least one of the call message requiring a particular service, the service trigger indication within the call message and a subscriber profile identified by the call message associated with the subscriber within the HLR, wherein the step of determining further comprises:

determining the service trigger and an identifier for the subscriber from the call message;

accessing the subscriber profile responsive to the determined identifier to identify active services for the subscriber;

determining the service logic unit to provide the particular service responsive to the service trigger and the active services for the subscriber;

determining an address of the service logic unit by accessing mapping logic; and

transmitting the call message requiring the particular service from the HLR to the determined service logic unit of the plurality of available service logic units to enable the determined service logic units to provide the particular service to the MSC.

6. The method of claim 5 , wherein the particular service comprises a WIN (wireless intelligent network) service provided by the service logic unit.

7. The method of claim 5 , wherein the MSC comprises a pre-WIN (wireless intelligent network) MSC.

8. A wireless network, comprising:

a mobile switching center (MSC) for controlling access to the wireless network by at least one subscriber;

a service specific service control point (SCP) for providing a particular service to the at least one subscriber responsive to an origination request (ORREQ) message;

a home location register (HLR) including a subscriber database for storing subscriber profiles for the at least one subscriber and mapping logic for determining a service control point responsive to at least one of the ORREQ message and a trigger indication within the ORREQ message, wherein the HLR does not know the service control point for providing the particular service;

wherein the MSC receives a service trigger to provide the particular service at the MSC from a subscriber and transmits the ORREQ message from the MSC to the HLR responsive to receipt of the service trigger; and

wherein the HLR determines the service specific SCP to provide the particular service of a plurality of available service specific SCPs responsive to at least one of the ORREQ message and the trigger indication within the ORREQ message and a subscriber profile associated with the subscriber within the HLR by accessing the subscriber profile and the mapping logic at the HLR and transmits the ORREQ message from the HLR to the determined service specific SCP of the plurality of available service specific SCPs to enable the determined service specific SCP to provide the particular service to the MSC.

9. The wireless network of claim 8 , wherein the HLR further determines the service trigger and an identifier for the subscriber from the ORREQ and accesses the subscriber profile in the subscriber database responsive to the determined identifier to identify active services for the subscriber to determine the service specific SCP providing the particular service responsive to the service trigger and the active services for the subscriber.

10. The wireless network of claim 9 , wherein the HLR further determines an address of the service specific SCP.

11. The wireless network of claim 10 wherein the HLR accesses a trigger address list to determine the address of the service specific SCP.

12. The wireless network of claim 8 service specific SCP transmits an ORREQ reply response message from the service specific SCP to the MSC through the HLR.

13. The wireless network of claim 8 , wherein the particular service comprises a WIN (wireless intelligent network) service provided by the service specific SCP.

14. The wireless network of claim 8 , wherein the MSC comprises a pre-WIN (wireless intelligent network) MSC.

15. A method for relaying an ORREQ (origination request) message from an MSC (mobile switching center) to a service specific SCP (service control point), comprising the steps of:

receiving at the MSC from a subscriber a service trigger to provide a particular service;

transmitting the ORREQ message from the MSC to an HLR (home location register), wherein the HLR does not know the service specific SCP required to provide the particular service;

determining at the HLR the service specific SCP to provide the particular service of a plurality of available service specific SCPs responsive to a user profile identified by the ORREQ message, wherein the step of determining further comprises:

determining the service trigger and an identifier for the subscriber from the ORREQ;

accessing the subscriber profile responsive to the determined identifier to identify active services for the subscriber;

determining the service specific SCP to provide the particular service responsive to the service trigger and the active services for the subscriber;

determining an address of the service specific SCP by accessing mapping logic; and

transmitting the ORREQ message from the HLR to the determined service specific SCP of the plurality of available service specific SCPs to enable the determined service specific SCP to provide the particular service to the MSC.
