Announcing a communication session within a wireless communications system

An access network configured to announce a communication session from within a wireless communications system operating in accordance with a given wireless communications protocol, comprising:

• means for receiving a call announcement message at the access network for transmission to an access terminal;
• means for initiating, in response to receipt of the call announcement message, a physical-layer synchronization procedure for at least one channel between the access network and the access terminal, the physical-layer synchronization procedure associated with a transition of the access terminal to a dedicated channel state;
• and
• means for transmitting the call announcement message on a downlink channel to the access terminal before the physical-layer synchronization procedure is complete.

An access network configured to announce a communication session from within a wireless communications system operating in accordance with a given wireless communications protocol, comprising:

• a processor coupled to a communications interface and configured to:
• receive a call announcement message at the access network for transmission to an access terminal;
• initiate, in response to receipt of the call announcement message, a physical-layer synchronization procedure for at least one channel between the access network and the access terminal, the physical-layer synchronization procedure associated with a transition of the access terminal to a dedicated channel state;
• and
• transmit the call announcement message on a downlink channel to the access terminal before the physical-layer synchronization procedure is complete.

A non-transitory computer-readable storage medium containing instructions which, when executed by an access network configured to announce a communication session from within a wireless communications system operating in accordance with a given wireless communications protocol, cause the access network to perform operations, the instructions comprising:

• program code to receive a call announcement message at the access network for transmission to an access terminal;
• program code to initiate, in response to receipt of the announcement message, a physical-layer synchronization procedure for at least one channel between the access network and the access terminal, the physical-layer synchronization procedure associated with a transition of the access terminal to a dedicated channel state;
• and
• program code to transmit the call announcement message on a downlink channel to the access terminal before the physical-layer synchronization procedure is complete.

A method of announcing a communication session from an access network within a wireless communications system operating in accordance with a given wireless communications protocol, comprising:

• receiving a call announcement message at the access network for transmission to an access terminal;
• transmitting, in response to receipt of the call announcement message, a reconfiguration message to the access terminal to facilitate a transition of the access terminal to a dedicated channel state;
• and
• transmitting the call announcement message on a downlink channel to the access terminal before a reconfiguration confirm message is received from the access terminal, the reconfiguration confirm message indicating that the access terminal has successfully transitioned to the dedicated channel state.
