System and method for sending IP packets to a mobile station transitioning from dormant state to active state
First Claim
1. A method for sending IP packets from a base station to a mobile station during transition of the mobile station from a dormant state to an active state, the method comprising the steps of:
- receiving a lagging feature request from the mobile station;
establishing a physical layer of a traffic channel between the base station and the mobile station;
establishing a network layer of the traffic channel between the base station and the mobile station; and
after establishing the physical layer of the traffic channel and while establishing the network layer of the traffic channel, packaging the IP packets in a first message format and sending the IP packets in the first message format to the mobile station, wherein the IP packets comprise a flow grant message, and wherein the flow grant message is buffered at the base station until the physical layer of the traffic channel between the mobile station and the base station is established.

Abstract
A method for sending IP packets from a base station to a mobile station during transition of the mobile station from a dormant state to an active state is provided. The method includes receiving a lagging feature request from the mobile station. A physical layer of a traffic channel is established between the base station and the mobile station. A network layer of the traffic channel is established between the base station and the mobile station. After the physical layer of the traffic channel is established and while the network layer of the traffic channel is being established, the IP packets are packaged and sent to the mobile station in a particular format.

8. A method for establishing a push-to-talk (PTT) event for an originating mobile station and a target mobile station, the method comprising the steps of:
-
sending a PTT event message from the originating mobile station to a first base station; receiving a flow grant message from the first base station at the originating mobile station before a network layer of a traffic channel between the originating mobile station and the first base station is established; and providing notification to a user of the originating mobile station that the flow grant message has been received, wherein the flow grant message is buffered at the first base station until a physical layer of the traffic channel between the originating mobile station and the first base station is established. - View Dependent Claims (9, 10, 11, 12, 13, 14)

- 15. A wireless network comprising a plurality of base stations capable of providing Push-to-Talk (PTT) service between a plurality of mobile stations, wherein said wireless network is capable of receiving from a first one of said plurality of mobile stations a request to send a PTT message to a second one of said plurality of mobile stations, and wherein said wireless network, in response to said request, is further capable of establishing a physical layer of a traffic channel between said first mobile station and a first one of said plurality of base stations and transmitting an authorization message from said first base station to said first mobile station in data frames of said physical layer of said traffic channel, wherein said authorization message comprises a flow grant message, and wherein the flow grant message is buffered at said first base station until the physical layer of the traffic channel between said first mobile station and the first base station is established.
