A method is provided for use with a packet data terminal (24) of a wireless communications system (10), the method being intended to respond to a receipt of a broadcast control channel message (BCCH) when camped on a digital control channel (DCCH). The method includes a first step of determining if the received BCCH contains a message that pertains to acquiring a packet control channel (PCCH). As presently specified, this message is a Beacon PCCH Parameters message. If it does, a next step initiates a PCCH event only if certain criteria are fulfilled. In a presently preferred embodiment of the invention, the certain criteria are selected from a set of criteria including a Queued Originate indicator not being set; packet data service being enabled and a determination that the packet data service of an acceptable Network Type is supported by the current DCCH; and packet data service being enabled and a determination that PCCH parameters found in the message are acceptable. Upon initiating the PCCH event, a next step of the method performs a PCCH selection operation with a PCCH that was specified in the message and, if the PCCH selection operation is successful, a further step transitions from the DCCH to the PCCH. |
