Quality of service (QoS) acquisition and provisioning within a wireless communications system

A method of setting up a group communication session requiring Quality of Service (QoS) resources at an application server configured to arbitrate the group communication session within a wireless communications system, comprising:

• configuring a message that is related to an access terminal's attempt to originate the group communication session to include a flag configured to prompt an access network to conditionally allocate QoS resources to the access terminal based on whether the QoS resources have already been allocated to the access terminal;
• and
• forwarding the configured message to the access network for transmission to the access terminal.

An application server configured to arbitrate a group communication session requiring Quality of Service (QoS) resources within a wireless communications system, comprising:

• means for configuring a message that is related to an access terminal's attempt to originate the group communication session to include a flag configured to prompt an access network to conditionally allocate QoS resources to the access terminal based on whether the QoS resources have already been allocated to the access terminal;
• and
• means for forwarding the configured message to the access network for transmission to the access terminal.

An application server configured to arbitrate a group communication session requiring Quality of Service (QoS) resources within a wireless communications system, comprising:

• logic configured to configure a message that is related to an access terminal's attempt to originate the group communication session to include a flag configured to prompt an access network to conditionally allocate QoS resources to the access terminal based on whether the QoS resources have already been allocated to the access terminal;
• and
• logic configured to forward the configured message to the access network for transmission to the access terminal.

A non-transitory computer-readable storage medium including instructions stored thereon, which, when executed by an application server configured to arbitrate a group communication session requiring Quality of Service (QoS) resources within a wireless communications system, causes the application server to perform operations, the instructions comprising:

• program code to configure a message that is related to an access terminal's attempt to originate the group communication session to include a flag configured to prompt an access network to conditionally allocate QoS resources to the access terminal based on whether the QoS resources have already been allocated to the access terminal;
• and
• program code to forward the configured message to the access network for transmission to the access terminal.
