SELECTIVELY PROVISIONING CALL SETUP QUALITY OF SERVICE (QoS) RESOURCE RESERVATIONS DURING A COMMUNICATION SESSION WITHIN A WIRELESS COMMUNICATIONS SYSTEM

摘要

dormant AT AT and the at least one target communication session start request to the receiving The. At this point, the AT does not have the QoS reservation for the IP flow associated with the call setup for a communication session that is associated with the active TCH or at least started. The AT transmits the configuration message requesting for an IP flow QoS resource reservation associated with the call set-up for the access network (AN), at least a communication session is initiated. AN gives a request for the QoS resource reservation for the IP flow. In one embodiment, AN may be granted QoS resource request by sending the AT on a TCH assigned a QoS resource reservation assignment message. Target AT''s session is also active TCH and received by the AN. At this point, the AT does not have the QoS reservation for the IP flow associated with the call setup for a communication session that is associated with the active TCH or at least started. The AT transmits the configuration message requesting for an IP flow QoS resource reservation associated with the call set-up for the access network (AN), at least a communication session is initiated. AN gives a request for the QoS resource reservation for the IP flow. In an embodiment, the AN assigns the QoS reservation by sending re-IP- flow QoS resources to the AT on the allocated QoS resources reserved allocation message TCH.
