Dynamic generation of CSI for outbound roamers

A system for providing Customized Applications for Mobile network Enhanced Logic (CAMEL) Subscription Information (CSI) of an outbound roamer of an Home Public Mobile Network (HPMN), wherein the outbound roamer is roaming in a Visited Public Mobile Network (VPMN), the system comprising:

• a roamers database storing an outbound roamer record of at least one outbound roamer, wherein the outbound roamer record comprises at least the International Mobile Subscriber Identity (IMSI) of the outbound roamer
• a detection block to detect whether provisioning of the CSI is required for the outbound roamer;
• a CSI generation block to dynamically generate the CSI of the outbound roamer based on at least the IMSI in the outbound roamer record, if the provisioning of the CSI is required;
• and
• a provisioning block to provision the generated CSI of the outbound roamer to at least one CSI storing node.

A method of providing Customized Applications for Mobile network Enhanced Logic (CAMEL) Subscription Information (CSI) of an outbound roamer of an Home Public Mobile Network (HPMN), wherein the outbound roamer is roaming in a Visited Public Mobile Network (VPMN), the method comprising:

• storing an outbound roamer record of at least one outbound roamer, wherein the outbound roamer record comprises at least the International Mobile Subscriber Identity (IMSI) of the outbound roamer;
• detecting whether provisioning of the CSI is required for the outbound roamer;
• dynamically generating the CSI of the outbound roamer based on at least the IMSI in the outbound roamer record of the outbound roamer, if the provisioning of the CSI is required;
• and
• providing the generated CSI of the outbound roamer to at least one CSI storing node.

A system for providing Mobile Terminated CAMEL Subscription Information (MT-CSI) of an outbound roamer of a Home Public Mobile Network (HPMN), wherein the outbound roamer is roaming in a Visited Public Mobile Network (VPMN), the system comprising:

• a monitoring block to monitor Mobile Application Part (MAP) transaction messages between a VPMN VLR/Visited Mobile Switch Center (VMSC) and a Home Location Register (HLR) of the HPMN;
• a roamers database storing an outbound roamer record of at least one outbound roamer, wherein the outbound roamer record comprises at least the International Mobile Subscriber Identity (IMSI) of the outbound roamer
• a detection block to detect whether provisioning of the MT-CSI is required for the outbound roamer;
• a CSI generation block to dynamically generate the MT-CSI of the outbound roamer based on at least the IMSI in the outbound roamer record, if the provisioning of the MT-CSI is required;
• and
• a provisioning block to provision the generated MT-CSI of the outbound roamer to at least one of the Home Location Register (HLR) of the HPMN and a HPMN Gateway Mobile Switch Center (GMSC).

A method for providing Mobile Originated CAMEL Subscription Information (MO-CSI) of an outbound roamer of a Home Public Mobile Network (HPMN) to a Visited Public Mobile Network (VPMN) Visited Location Register (VLR), wherein the outbound roamer is roaming in a VPMN, the method comprising:

• monitoring Mobile Application Part (MAP) transaction messages between the VPMN VLR/VMSC and a Home Location Register (HLR) of the HPMN for storing an outbound roamer record, wherein the outbound roamer record comprises at least the International Mobile Subscriber Identity (IMSI) of the outbound roamer;
• detecting whether provisioning of the MO-CSI is required for the outbound roamer;
• identifying the phase of CAMEL supported by the VPMN;
• dynamically generating the MO-CSI of the outbound roamer based on at least one of the IMSI in the outbound roamer record of the outbound roamer and the phase of CAMEL supported by the VPMN, if the provisioning of the MO-CSI is required;
• and
• providing the generated MO-CSI of the outbound roamer to at least one CSI storing node.

A method for providing Mobile Terminated CAMEL Subscription Information (MT-CSI) of an outbound roamer of a Home Public Mobile Network (HPMN), wherein the outbound roamer is roaming in a Visited Public Mobile Network (VPMN), the method comprising:

• monitoring Mobile Application Part (MAP) transaction messages between a VPMN VLR/VMSC and a Home Location Register (HLR) of the HPMN for storing an outbound roamer record;
• storing an outbound roamer record of at least one outbound roamer, wherein the outbound roamer record comprises at least the International Mobile Subscriber Identity (IMSI) of the outbound roamer;
• detecting whether provisioning of the MT-CSI is required for the outbound roamer;
• dynamically generating the MT-CSI of the outbound roamer based on the IMSI in the outbound roamer record of the outbound roamer, if the provisioning of the MT-CSI is required;
• and
• providing the generated MT-CSI of the outbound roamer to at least one of HPMN HLR and HPMN Gateway Mobile Switch Center (GMSC).
