Method and system for providing CAMEL services to a home network's outbound roamer without need for CAMEL support or agreement

A method for enabling support of Intelligent Network (IN) services for an outbound roamer of a Home Public Mobile Network (HPMN) in a Visited Public Mobile Network (VPMN), the outbound roamer having a mobile device, the HPMN having an associated gateway, a service node and a Signaling Control Point (SCP), the method comprising:

• at the gateway, upon detecting a successful location update of the outbound roamer, receiving encapsulated IN messages over one or more bearers wherein the HPMN is unable to support at least one selected from a group consisting of exchange of IN messages and an IN agreement;
• facilitating, via the gateway, communication with the service node and the SCP, wherein the gateway translates the received encapsulated IN messages into a protocol that is compatible with at least one selected from a group consisting of the service node and the SCP;
• and
• managing the outbound roamer's IN services via the gateway and one of the service node and the SCP, by updating one or more traffic control conditions of the outbound roamer based on recognition of the received encapsulated IN messages.

A method for enabling support of Intelligent Network (IN) services for an outbound roamer of a Home Public Mobile Network (HPMN) in a Visited Public Mobile Network (VPMN), the outbound roamer having a mobile device and being coupled to a client, the HPMN having an associated gateway, a service node and a Signaling Control Point (SCP), the method comprising:

• sending, via the client, encapsulated IN messages over one or more bearers, after a successful location update of the outbound roamer, wherein the HPMN is unable to support exchange of IN messages and an IN agreement;
• facilitating communication between the client and one of the service node and the SCP, wherein the exchanged encapsulated IN messages are translated in a protocol compatible with one selected from a group consisting of the service node and the SCP;
• and
• managing the outbound roamer's IN services via one of the service node and the SCP by updating, at the client, one or more traffic control conditions of the outbound roamer based on recognition of the exchanged encapsulated IN messages.

A system for enabling support of Intelligent Network (IN) services for an outbound roamer of a Home Public Mobile Network (HPMN) in a Visited Public Mobile Network (VPMN), the outbound roamer having a mobile device, the HPMN having an associated gateway, a service node and a Signaling Control Point (SCP), the system comprising:

• a client coupled to the outbound roamer's mobile device;
• and
• a gateway in the HPMN for enabling the client based on observation of exchange of one or more parameters with the client, upon detecting a successful location update of the outbound roamer in a VPMN;
• wherein the gateway enables the client by exchanging encapsulated IN messages with the client over one or more bearers when at least one of the HPMN and the VPMN is unable to support at least one selected from a group consisting of exchange of IN messages and an IN agreement;
• wherein the gateway facilitates communication between the client and one selected from a group consisting of the service node and the SCP, by translating the encapsulated IN messages in a protocol compatible with the selected one of the service node and the SCP;
• and
• wherein the gateway and the selected one of the service node and the SCP manage the outbound roamer's IN based services from the HPMN by updating, at the client, one or more traffic control conditions of the outbound roamer, based on recognition of the exchanged encapsulated IN messages.
