Abstract

An inter-working network includes a plurality of interfaces for facilitating communications with a plurality of dispatch networks, a signaling controller, a media gateway and a system for facilitating the monetization of inter-carrier dispatch communications. The signaling controller and media gateway generate dispatch call records for dispatch sessions facilitated through the inter-working network. The system includes a billing accumulator and a settlement entity. The billing accumulator is interfaced with the inter-working network and includes logic to receive and store the dispatch call data records from the inter-working architecture. The settlement entity is interfaced with the billing accumulator, and includes settlement logic for converting each stored dispatch call data record to a billing record for each of at least two of the dispatch networks.

Claims

1. A system for facilitating the monetization of inter-carrier dispatch communications comprising:

an inter-working network facilitating communications between a plurality of different dispatch networks and comprising a plurality of interfaces, wherein the inter-working network includes a plurality of points-of-presence (POPs) configured to generate call detail records and usage data reports;

an originating dispatch network operated by a first carrier and interfaced to at least one of the POPs via a first border gateway associated with the first carrier;

a target dispatch network operated by a second carrier and interfaced to at least one other of the POPs via a second border gateway associated with the second carrier;

a billing accumulator interfaced with the plurality of POPs, the billing accumulator including logic to collect and store dispatch call data records received from the plurality of POPs; and

a settlement entity interfaced with the billing accumulator, the settlement entity including settlement logic for converting each stored dispatch call data record to a billing record for each of the originating and target dispatch networks.

2. The system of claim 1 wherein the inter-working network includes a signaling controller adapted to manage a dispatch session between the originating dispatch network and the target dispatch network, and wherein the billing accumulator receives the dispatch call data records from the signaling controller.

3. The system of claim 2 wherein the inter-working network includes a media gateway adapted to convert real-time media between the originating dispatch network and the target dispatch network, and wherein the billing accumulator receives the dispatch call data records directly from the media gateway.

4. The system of claim 2 wherein the inter-working network includes a media gateway adapted to convert real-time media between the originating dispatch network and the target dispatch network, and wherein the billing accumulator receives the dispatch call data records from the media gateway via the signaling controller.

5. The system of claim 2 further comprising a contract entity interfaced with the settlement entity, the contract entity storing rules for converting the stored dispatch call data records to billing records in accordance with terms associated with the originating and target dispatch networks involved in the session, the stored rules directing the settlement logic.

6. The system of claim 5 further comprising an administrative entity interfaced with the inter-working network, the administrative entity receiving address translations from the inter-working architecture.

7. The system of claim 6 wherein the address translations are used to identify end users and dispatch networks associated with the dispatch session, and corresponding settlement rules to be applied to the received dispatch call data records.

8. The system of claim 1 wherein the billing accumulator is further interfaced with a first of the plurality of dispatch networks, the billing accumulator receiving roaming call data records from the first dispatch network for a roaming subscriber of the second dispatch network, the roaming call data records defining dispatch calls wherein at least one of the dispatch callers is the roaming subscriber of the second dispatch network.

9. An inter-working network for inter-working a plurality of dispatch networks, the network comprising:

a billing clearinghouse storing call detail records and usage data reports relating to dispatch sessions implemented across the plurality of dispatch networks;

a plurality of points-of-presence (POPs) connected to the billing clearinghouse, the POPs generating the call detail records and usage data reports; and

a plurality of border gateways configured to interface one of the POPs to an originating dispatch network operated by a first carrier, and to interface another one of the POPs to a target dispatch network operated by a second carrier, wherein the originating dispatch network and the target dispatch network have incompatible technologies.

10. The network of claim 9 wherein each point-of-presence interfaces with a core inter-working network to locate the target dispatch network associated with a target user, and wherein each point-of-presence is adapted to determine a regional point-of-presence serving the target dispatch network.

11. The network of claim 9 wherein the billing clearinghouse generates billing data for the originating dispatch network and billing data for the target dispatch network in accordance with the call detail records and usage data reports associated with the dispatch session.

12. The network of claim 9 wherein the billing clearinghouse generates an invoice to each of the originating dispatch network and the target dispatch network in accordance with each dispatch network'"'"'s respective billing terms and conditions.

13. A method for monetizing, via an inter-working network, a plurality of disparate dispatch networks, each dispatch network providing dispatch services to a plurality of subscriber units, comprising the steps of:

receiving, by the inter-working network, a dispatch session request from an originating dispatch network operated by a first carrier via a first border gateway associated with the first carrier, the dispatch session request identifying a target user, wherein the inter-working network includes a plurality of points-of-presence (POPs) configured to generate call detail records and usage data reports;

processing, in at least one of the plurality of POPs, the dispatch session request, including allocating signaling and media resources;

forwarding, by the inter-working network using at least one other of the POPs, the dispatch session request to a second border gateway associated with a target dispatch network operated by a second carrier;

facilitating, by the inter-working network, the dispatch session between the originating dispatch network and target dispatch network; and

generating an invoice for each of the originating dispatch network and target dispatch network, including charges for facilitating the dispatch session.

14. The method of claim 13 wherein the signaling resources are allocated in a first point-of-presence and media resources are allocated in a second point-of-presence, each point-of-presence generating dispatch call data for the dispatch session.

15. The method of claim 14 further comprising aggregating the generated dispatch call data and usage data for the dispatch session.

16. The method of claim 15 further comprising applying settlement logic to the aggregated dispatch call data to produce billing data for each of the originating dispatch network and the target dispatch network.

17. The method of claim 16 wherein the settlement logic is associated with the originating dispatch network and the target dispatch network.

18. The method of claim 17 wherein the settlement logic applied to each dispatch call data record is further associated with the point-of-presence that generated the dispatch call data record.

19. The method of claim 18 wherein the settlement logic includes a set of criteria comprising at least one of a number of PTT button pushes requesting a session floor, a number of regions, a size of participating carriers, a group size for the session, a number of carriers involved in the session, a number of bytes transmitted, an identity of transcoding resources allocated, and an identify and duration of inter-working applications used.

20. The method of claim 13 further comprising:

receiving a request for an inter-working application; and

executing the inter-working application during the session,

wherein the invoice includes charges for the use of the inter-working application.
