Integrated authentication codes for user devices and communication networks
First Claim
1. A method of operating a data communication system to transfer user/network authentication information for a communication session wherein first originating User Equipment (UE) transfers a first communication session request having a first calling party identifier and a first calling party digital signature for the first calling party identifier, the method comprising:
- a first originating communication network receiving the first communication session request from the first originating UE and verifying the first calling party digital signature for the first calling party identifier;
the first originating communication network transferring the first communication session request having the first calling party identifier, a first user code indicating that the first calling party identifier was digitally verified by the first originating communication network, and a first originating network digital signature for the first originating communication network;
a tandem communication network receiving the first communication session request having the first originating network digital signature for the first originating communication network and verifying the first originating network digital signature for the first originating communication network;
the tandem communication network transferring the first communication session request having the first calling party identifier and a first user/network code indicating that the first calling party identifier was digitally verified by the first originating communication network and that the first originating communication network was digitally verified by the tandem communication network; and
the tandem communication network receiving a second communication session request for a second originating UE from a second originating communication network without a second user code and without a second originating network digital signature and transferring the second communication session request with a second user/network code indicating that the second originating communication network was not digitally verified by the tandem communication network.

Abstract
User Equipment (UE) transfers a session request having a calling party identifier and a digital signature for the calling party identifier. An originating network receives the session request and digitally verifies the calling party digital signature for the calling party identifier. The originating network transfers the session request having the calling party identifier, a user code indicating that the calling party identifier was digitally verified by the originating network, and an originating network digital signature for the originating network. A tandem network receives the session request having the originating network digital signature and digitally verifies the originating network digital signature. The tandem network transfers the communication session request having the calling party identifier and a user/network code indicating that the calling party identifier was digitally verified by the originating communication network and that the originating network was digitally verified by the tandem communication network.

10. A data communication system to transfer user/network authentication information for a communication session wherein first originating User Equipment (UE) transfers a first communication session request having a first calling party identifier and a first calling party digital signature for the first calling party identifier, the data communication system comprising:
-
a first originating communication network configured to receive the first communication session request from the first originating UE, verify the first calling party digital signature for the first calling party identifier, and transfer the first communication session request having the first calling party identifier, a first user code indicating that the first calling party identifier was digitally verified by the first originating communication network, and a first originating network digital signature for the first originating communication network; a tandem communication network configured to receive the first communication session request having the first originating network digital signature for the first originating communication network and verify the first originating network digital signature for the first originating communication network, and transfer the first communication session request having the first calling party identifier, and a first user/network code indicating that the first calling party identifier was digitally verified by the first originating communication network and that the first originating communication network was digitally verified by the tandem communication network; and the tandem communication network configured to receive a second communication session request for a second originating UE from a second originating communication network without a second user code and without a second originating network digital signature and transfer the second communication session request having a second user/network code indicating that the second originating UE was not digitally verified by the second originating communication network that the second originating communication network was not digitally verified by the tandem communication network. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
