System and method for sending data to a mobile device in a wireless network

Abstract

A device for wirelessly transmitting data under a wireless protocol is contemplated. A remote wireless network device initiates a session with a network. In this manner, information is sent to a gateway associated with the access point that couples the remote wireless network device to the network. When the remote wireless network device moves, data is tunneled between the succeeding gateway and the original gateway, but for those sessions opened at the original gateway. Any sessions associated with the remote wireless network device at the new gateway are processed and maintained by the new gateway without tunneling the data.

1 . A device for sending data to one or more wireless devices in a wireless network, the data being time constant digital data, the device comprising: 
 a first circuit for alerting the wireless devices that the time constant digital data is to be sent;    a second circuit for defining a frame in which the time constant digital data is to be sent; and    a third circuit for sending the digital data to the one or more wireless devices.    
   
   
       2 . A device for sending data to a plurality of wireless devices in a wireless network, the data being time constant digital data, the device comprising: 
 a first circuit for alerting the wireless devices that the time constant digital data is to be sent;    a second circuit for defining a frame in which the time constant digital data is to be sent; and    a third circuit for sending the digital data as a single data block to the plurality of wireless devices within the frame.    
   
   
       3 . A device for receiving data at one of a plurality of wireless devices in a wireless network, the data being time constant digital data, the device comprising: 
 a first circuit for receiving an alert that the time constant digital data is to be sent;    a second circuit for receiving parameters regarding a frame in which the time constant digital data is to be sent;    a third circuit for receiving the digital data as a single data block to the plurality of wireless devices within the frame; and    a fourth circuit for extracting the digital data bound for the one of a plurality of wireless devices from the single block of data.    
   
   
       4 . A device for receiving data from one or more wireless devices in a wireless network, the data being time constant digital data, the device comprising: 
 a first circuit for alerting the wireless devices that the time constant digital data is to be sent;    a second circuit for defining a frame in which the time constant digital data is to be sent;    a third circuit for polling the particular wireless device to initiate the sending of the digital data; and    a fourth circuit for receiving the data sent from each particular polled wireless device.    
   
   
       5 . A method for receiving digital data from a wireless device in a wireless network, the method comprising: 
 alerting the wireless device to send the time constant data;    polling the wireless device to send the time constant data; and    receiving a sent packet of time constant data from the particular wireless device.    
   
   
       6 . A method for sending digital data from a wireless device in a wireless network, the method comprising: 
 awaiting an Alert to send the time constant data;    subsequent to the alert, awaiting a Poll to send the time constant data;    sending a sent packet of time constant data from the particular wireless device.    
   
   
       7 . A method for sending digital data to a plurality of wireless devices in a wireless network, the method comprising: 
 alerting the plurality of wireless devices to receive the time constant data; and    sending one block of data, the one block of data comprising all of the data destined for the plurality of wireless devices.
