ABSTRACT:
A method of re-using authentication triplets on inter-VLR location updates in a wireless communication network. The method reduces the amount of work on the MSC and HLR, and thus significantly increases the capacity of a high mobility MSC and the HLR to increase the number of mobile subscribers each node in the wireless communication network can support. The number of times the MSC must request new authentication triplets from the HLR, and thus the number of authentication triplets the HLR must return, is reduced to increase the capacity on the MSC and HLR, particularly in a GSM network.
