Abstract
A method, translating apparatus, apparatus comprising a computer readable medium, and system for establishing and terminating an end-to-end connection in a mixed protocol communication network includes a translation function that communicates with a first device using a first communication protocol and a second device using a second communication protocol. In order to establish an end-to-end connection, the translation function receives a first control message from the second device initiating a connection between the second device and the translation function, completes a connection establishment procedure with the second device, receives a first data message from the second device, and transmits a second data message to the first device. In order to terminate an end-to-end connection, the translation function receives a first control message from the second device terminating the connection between the second device and the translation function, completes a link reset procedure with the first device, and then completes a connection termination procedure with the second device.
