Abstract

An approach for immediate channel assignment in a wireless communications system involves receiving a channel request message from a wireless transceiver, the channel request message including a dialed party number; forming an immediate assignment message including a channel assignment; transmitting the immediate assignment message to the wireless transceiver; and establishing a communications channel between the wireless transceiver and a called party by establishing a channel between the wireless transceiver and the called party.

Claims

1. A method for immediate channel assignment in a wireless communications system comprising:

receiving a channel request message over a contention channel from a wireless transceiver at a gateway, wherein the channel request message includes at least a portion of a called party number, wherein the receiving occurs prior to the establishment of a signaling channel for the wireless transceiver;

forming an immediate assignment message including a channel assignment;

transmitting the immediate assignment message to the wireless transceiver prior to the establishment of a signaling channel for the wireless transceiver;

establishing the signaling channel for the wireless transceiver;

determining whether said at least a portion is a complete called party number;

transmitting to the wireless transceiver an immediate assignment message with an indication to initiate extended assignment procedures; and

receiving from the wireless transceiver an extended channel request message comprising a complete called party number.

2. A system for immediate channel assignment comprising:

a wireless communications system comprising;

a gateway receiving a channel request message over a contention channel from a wireless transceiver, the channel request message including at least a portion of a called party number and wherein the receiving occurs prior to the establishment of a signaling channel for the wireless transceiver, forming an immediate assignment message including a channel assignment, transmitting the immediate assignment message to the wireless transceiver prior to the establishment of a signaling channel for the wireless transceiver, and establishing the signaling channel for the wireless transceiver;

the wireless transceiver transmitting to the gateway, the channel request message including the called party number, and receiving the immediate assignment message from the gateway; and

a satellite link passing communications between the gateway and the wireless transceiver through a satellite,

wherein said gateway includes;

means for determining whether said at least a portion is a complete called party number;

means for transmitting to the wireless transceiver an immediate assignment message with an indication to initiate extended assignment procedures; and

means for receiving from the wireless transceiver an extended channel request message comprising a complete called party number.

3. A method for immediate channel assignment in a wireless communications system comprising:

receiving a channel request message over a contention channel from a wireless transceiver at a gateway, wherein the channel request message includes at least a portion of a called party number, wherein the receiving occurs prior to the establishment of a signaling channel for the wireless transceiver;

forming an immediate assignment message including a channel assignment;

transmitting the immediate assignment message to the wireless transceiver;

establishing the signaling channel for the wireless transceiver;

determining whether said at least a portion is a complete called party number;

transmitting to the wireless transceiver an immediate assignment message with an indication to initiate extended assignment procedures; and

receiving from the wireless transceiver an extended channel request message comprising a complete called party number.

4. A system for immediate channel assignment comprising:

a wireless communications system comprising;

a gateway receiving a channel request message over a contention channel from a wireless transceiver, the channel request message including at least a portion of a called party number and wherein the receiving occurs prior to the establishment of a signaling channel for the wireless transceiver, forming an immediate assignment message including a channel assignment, transmitting the immediate assignment message to the wireless transceiver, and establishing the signaling channel for the wireless transceiver;

the wireless transceiver transmitting to the gateway, the channel request message including the called party number, and receiving the immediate assignment message from the gateway; and

a satellite link passing communications between the gateway and the wireless transceiver through a satellite;

wherein said gateway includes;

means for determining whether said at least a portion is a complete called party number;

means for transmitting to the wireless transceiver an immediate assignment message with an indication to initiate extended assignment procedures; and

means for receiving from the wireless transceiver an extended channel request message comprising a complete called party number.
