Abstract:
1. A multiple-protocol home location register comprising: a receiver for receiving, from a first standard HLR of a requesting network of at least two networks and without a requirement for any modification to the first standard HLR, a network request according to one of at least two network protocols; a processor, within the multiple-protocol home location register, wherein the processor is arranged and constructed to generate network messages according to the at least two network protocols and to process the network request to obtain information requested by the network request; a transmitter, operably coupled to the processor, for relaying the requested information to at least one of the requesting network and a destination network; a mediation device; wherein the requesting network comprises the first standard HLR and a first mobile switching center that communicate through employment of a first network protocol of the at least two network protocols; wherein the destination network comprises a second standard HLR and a second mobile switching center that communicate through employment of a second network protocol of the at least two network protocols; wherein the multiple-protocol home location register performs a call delivery of a call that originates at a communication device in the requesting network and terminates in the destination network; wherein the first mobile switching center receives an initial address message from the communication device through employment of the first network protocol, wherein the initial address message comprises a called party number; wherein the first mobile switching center sends routing information to the first standard HLR in response to the initial address message through employment of the first network protocol; wherein the first standard HLR determines that the destination network employs the second network protocol; wherein the first standard HLR sends a provide roaming number message with a first mobile switching center address and first network protocol type to the mediation device; wherein the mediation device stores the first mobile switching center address and the first network protocol type; wherein the mediation device converts the provide roaming number message to a location request message in the second network protocol, wherein the location request message comprises a mobile switching center identification that identifies the mediation device; wherein the mediation devices sends the location request message to the second standard HLR; wherein the second standard HLR sends a route request message to the second mobile switching center through employment of the second network protocol, wherein the route request message comprises the mobile switching center identification that identifies the mediation device; wherein the second mobile switching center sends an acknowledgement message to the second standard HLR in response to the route request message through employment of the second network protocol, wherein the acknowledgement message comprises a temporary location directory number; wherein the second standard HLR relays the acknowledgement message to the mediation device through employment of the second network protocol; wherein the mediation device sends a provide roaming number acknowledgement with a mobile subscribing roaming number to the first standard HLR through employment of the first network protocol; wherein the first standard HLR sends a send routing information acknowledgement to the first mobile switching center through employment of the first network protocol, wherein the send routing information acknowledgement comprises the mobile subscribing roaming number; wherein the first mobile switching center sends the initial address message with the mobile subscribing roaming number to the second mobile switching center; wherein the second mobile switching canter completes the call to the destination network.
