Abstract:
A method for a communication unit to shorten call-setup time comprising the steps of:receiving, by the communication unit from a communication infrastructure, an indication that the communication infrastructure will transmit a page addressed to at least one communication unit of a group of communication units in a paging slot but that does not indicate specifically which communication unit will be addressed, wherein the communication unit is a member of the group; transmitting, by the communication unit to the communication infrastructure, a page response message in response to the indication; receiving, by the communication unit from the communication infrastructure, at least one page message in the paging slot addressed to a communication unit in the group after receiving the indication but before the step of transmitting the page response message in response to the indication; and determining, by the communication unit, whether the at least one page message was addressed to the communication unit, wherein the step of transmitting the page response message in response to the indication comprises the step of preventing the transmission of the pace response message in response to the indication, when none of the at least one page message is determined to be addressed to the communication unit.
