Abstract
Calls in the satellite radiotelephone system are conducted as single or dual hop calls under the control of a satellite radiotelephone that initiates the call. In particular, a first satellite radiotelephone calling a second satellite radiotelephone can configure the call as a dual hop call by transmitting a suspension code to a switching center, thereby possibly avoiding a default action by the switching center to conduct the call a single hop call. The switching center recognizes the suspension code and conducts the call in the active state to the second satellite radiotelephone as a dual hop call. In other words, the suspension code transmitted by the first satellite radiotelephone instructs the switching center to avoid conducting the call as a single hop call which may be the default action performed by the switching center.
