METHOD AND APPARATUS FOR CALL SETUP LATENCY REDUCTION
First Claim
1. A method for initiating mobile station terminated call setup without paging, the mobile station being in the idle state, comprising:
- the mobile station entering the system access state to deliver to a base station a pilot strength measurement 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.

5. A wireless communication system for initiating mobile station terminated call setup without paging, comprising:
-
a first station; and
a second station for receiving a pilot strength measurement message from the first station, conditioned on the first station'"'"'s reception of one or more additional pilot signals at a strength exceeding a threshold, and for sending a channel assignment message to the first station with active set information based on the pilot strength measurement message.

6. A wireless communication system for initiating first station terminated call setup without paging, comprising:
-
a second station; and
a first station for receiving a channel assignment message with previously used active set information, and for conditionally sending the second station a pilot strength measurement message when one or more additional pilot signals are received which exceed a threshold.
