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

摘要

A method for relaying a call message requiring a particular service from an MSC to a service logic unit, involves the steps of receiving a service request trigger to provide a particular service at the MSC from a subscriber. The call message requiring a particular service is transmitted from the MSC to an HLR. The HLR determines the service logic unit to provide the particular service responsive to at least one of the call message requiring a particular service, a trigger indication and a subscriber profile associated with the subscriber. The call message requiring a particular service is transmitted from the HLR to the determined service logic unit.

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.
