| 1. A power saving method for a multimode wireless terminal which includes at least two modems for processing information for
different communication networks, said method comprising the steps of:
registering connection information of the multimode wireless terminal with a terminal information management equipment through
a first communication network from a first modem of the multimode wireless terminal when a main power of the multimode wireless
terminal is turned on;
determining whether a second modem of the multimode wireless terminal receives a turn-on signal from a main controller of
the multimode wireless terminal when a call-processing is not existing;
maintaining the second modem in a power-off state when the turn-on signal is not received by the second modem, and placing
the second modem in a power-on state for establishing a connection to a second communication network when the turn-on signal
is received by the second modem; and
selecting one of the first and second communication networks to be accessible when the call-processing is existing;
wherein the connection information includes a unique terminal number of the multimode wireless terminal and a location and
identification information of the multimode wireless terminal.
