Abstract

Techniques for minimizing call setup latency are disclosed. In one aspect, a channel assignment message is sent with a flag to direct the use of previously negotiated service parameters. This aspect eliminates the need for service negotiation messages. In another aspect, a channel assignment message is sent with an active set identifier instead of an active set and its parameters. This aspect reduces the transmission time of the channel assignment message. In yet another aspect, call setup without paging is facilitated by a mobile station (106) sending a pilot strength measurement message between active communication sessions, such that a channel assignment message can be used for mobile station terminated call setup without the need for mobile station paging and related messages.

Claims

1. A wireless communication system operably coupled with a network comprising:

a first station for sending a second station an origination message including a short data burst information packet for initiation of call setup and delivery of the short data burst information packet to a network destination, wherein the origination message further comprises a list of pilot signals from neighboring base stations received at the first station.

2. A method for call setup in a wireless communication system, comprising:

sending an origination message to a base station for initiation of call setup, wherein the origination message comprises a short data burst information packet and the origination message is for delivery of the short data burst information packet, wherein the origination message further comprises a list of pilot signals from neighboring base stations received at a first station.

3. A method for call setup in a wireless communication system, comprising:

receiving an origination message, wherein the origination message comprises a short data burst information packet for initiation of call setup and the origination message is for delivery of the short data burst information packet, wherein the origination message further comprises a list of pilot signals from neighboring base stations received at a first station; and

sending the short data burst information packet to a first switching center.

4. A mobile station used to set up a call in a wireless communication system, comprising:

a memory; and

a digital signal processing device communicatively coupled to the memory, the digital signal processing device for executing instructions to;

send an origination message to a base station for initiation of call setup, wherein the origination message comprises a short data burst information packet and the origination message is for delivery of the short data burst information packet, wherein the origination message further comprises a list of pilot signals from neighboring base stations received at the mobile station.

5. A base station used to set up a call in a wireless communication system, comprising:

a memory; and

a digital signal processing device communicatively coupled to the memory, the digital signal processing device for executing instructions to;

receive an origination message, wherein the origination message comprises a short data burst information packet for initiation of call setup and the origination message is for delivery of the short data burst information packet, wherein the origination message further comprises a list of pilot signals from neighboring base stations received at a first station; and

send the short data burst information packet to a first switching center.

6. A mobile station used to set up a call in a wireless communication system, comprising:

means for including a short data burst information packet in an origination message; and

means for sending the origination message to a base station for initiation of call setup, wherein the origination message comprises the short data burst information packet and the origination message is for delivery of the short data burst information packet, wherein the origination message further comprises a list of pilot signals from neighboring base stations received at the mobile station.

7. A base station used to set up a call in a wireless communication system, comprising:

means for receiving an origination message, wherein the origination message comprises a short data burst information packet to be sent to a first switching center, wherein the short data burst information packet is for initiation of call setup and the origination message is for delivery of the short data burst information packet, wherein the origination message further comprises a list of pilot signals from neighboring base stations received at a first station; and

means for sending the short data burst information packet to the first switching center.

8. A non-transitory computer readable medium having computer executable instructions for:

sending an origination message to a base station for initiation of call setup, wherein the origination message comprises a short data burst information packet and the origination message is for delivery of the short data burst information packet, wherein the origination message further comprises a list of pilot signals from neighboring base stations received at a first station.

9. A non-transitory computer readable medium having computer executable instructions for:

receiving an origination message, wherein the origination message comprises a short data burst information packet for initiation of call setup and the origination message is for delivery of the short data burst information packet, wherein the origination message further comprises a list of pilot signals from neighboring base stations received at a first station; and

sending the short data burst information packet to a first switching center.
