Abstract: A packet core network (PCN) includes a plurality of interconnected routers. An emulator is provided along with at least one of the routers and operates to control transmission of Internet Protocol (IP) datagrams there through in order to simulate the effects of having one of the non-radio inter-router connections fictionally comprise a wireless cellular radio link. The emulator responds to user input specifying wireless cellular radio link conditions to determine a time delay to be applied by the router against the transmission of each datagram. This time delay is set roughly equivalent to the delay introduced, under the user specified wireless cellular radio link conditions, by emulated radio link operation to erase uncorrectable frames to obtain retransmission. The emulator further sets a data rate for router handling of datagrams based on the user input to simulate congestion on the radio link due to the presence of other, competing users.

An emulator is provided along with at least one of the routers and operates to control transmission of internet protocol (IP) datagrams therethrough in order to simulate the effects of having one of the non-radio interrouter connections fictionally comprise a wireless cellular radio link. The emulator responds to user input specifying wireless cellular radio link conditions (such as, for example, number of users, bit error rate, signal to noise ratio, frame erasure rate, mobile platform speed, and mobile to base distance) to determine a time delay to be applied by the router against the transmission of each datagram. This time delay is set roughly equivalent to the delay introduced, under the user specified wireless cellular radio link conditions, by emulated radio link operation to erase uncorrectable frames and obtain retransmission.
