Abstract
For a network server () communicating with a wireless unit () via a Session Initiation Protocol, a retransmission method () first sets a timer based upon a time likely for a mobile unit to respond (). Then the network server waits for a response (). When the timer set for the kind of mobile unit being used expires (), a retransmit of the original SIP request takes place (). Optionally, modes for waiting may include a linear mode () and an exponential mode ().
