Paging messages are transmitted by a wireless communications network to mobile terminals, which have been in an idle state or dormant mode and which have waiting calls/data from their associated peer entities, in accordance with the qualities of service (QoS) associated with the waiting calls/data, where the QoS associated each waiting call/data includes a type of the call/data. To make paging of mobile terminal QoS aware, a QoS field is included in the Paging Announce requests sent from an RNC to another RNC, or from an RNC to a BTS. The QoS field includes: a QoS class of service of the waiting call/data indicating the type of the waiting call; a grade of service of the waiting call/data to which the mobile terminal is subscribed; and, optionally, other QoS service flow parameters whose presence depends on the type of wireless technology being used in the network.
1. In a wireless communication network in which a paging message is transmitted to wakeup an idle or dormant mobile terminal and reestablish a connection of the mobile terminal to the wireless network when a call/data for the idle or dormant mobile terminal is waiting in the network and further wherein a control node in the wireless network maintains an active call session state for a call associated with a given dormant mobile terminal, a method comprising:
providing at the control node a Quality of Service (QoS) parameter associated with a transmission priority for the active call session, the QoS parameter including at least a service class including an indication of a type of a waiting call/data for the active call session, wherein the type of the waiting call/data is used to determine bandwidth that is needed for the waiting call/data;
attaching the QoS parameter to a Paging Announce message transmitted from the control node to a base transceiver station (BTS) associated with a paging area for the given dormant mobile terminal; and
if a plurality of paging messages are waiting to be broadcast from the BTS receiving the Paging Announce message, prioritizing the order in which the plurality of paging messages are transmitted in accordance with the QoS parameter, wherein at least one of plurality of paging messages includes a reserve parameter for reserving network resources for the given dormant mobile terminal to reestablish the connection to the wireless network.
