Method and apparatus for call setup latency reduction
First Claim
1. A method for call setup in a wireless communication system comprising:
- sending a channel assignment message from a first station to a second station to direct the use of previously negotiated service parameters, wherein the channel assignment message includes previously used active set information; and
the second station sending an authentication message to the first station on a traffic channel set up in response to the channel assignment message.

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.

12. An apparatus used to set up a call in a wireless commumcation system, comprising:
-
memory; and a digital signal processing device communicatively coupled to the memory, the digital signal processing device capable of executing instructions to send channel assignment message from a first station to a second station to direct the use of previously negotiated service parameters, wherein the channel assignment message includes previously used active set information, the digital signal processing device further capable of receiving an authentication message on a traffic channel set up in response to the channel assignment message.
