Abstract

No. 8,045,990 on Oct. 25, 2011, which is a continuation of U.S. patent application Ser. No. 09/288,229, filed Apr. 8, 1999, which issued as U.S. Pat.

- The present invention relates to a wireless communication system. In particular, the present invention relates to systems and methods for providing wireless connections between a wireless access device and a network.
- Wireless access for computing networks is known in the art. Typically such systems are implemented by a layered wireless communication system. Layered communication systems are characterized by levels of processing that are performed for transmission and reception of a data signal. For example, a “physical layer” typically refers to processing that is performed to package a signal for radio transmission; it may include error coding, data interleaving digital code modulation, and other conventional processing. The physical layer can he contrasted with, for example, a “data layer” that performs processing to format a signal into a format appropriate for delivery for the wireless device to the subscriber terminal.
- Prior-art systems are disadvantageous because the wireless access device maintains a channel on a physical layer when the subscriber terminal needs to maintain an active channel, even if there is no payload data being transferred over the physical channel. This system is bandwidth inefficient because data transmissions in computer networks are “bursty,” characterized by a short transfer of high-rate data, followed by a relatively long period in which no data are transferred. This inefficiency reduces the number of subscribers that can be working on a system,
- Thus a need exists for a system in which a subscriber and a wireless-access device can communicate along a layer of the connection, without activating the physical layer until payload data is intended to be sent.
- To alleviate the problems inherent in the prior art, systems and methods are introduced to provide wireless communication to a network.
- In ODE embodiment of the present invention, a wireless access device determines whether payload data has been received from a subscriber's terminal. If so, a first set of traffic channels is requested, and the payload data is transmitted via the first set of traffic channels. A release message can then be sent, thereby freeing the traffic channels from use.

Wireless access device 103 can receive payload data fromsubscriber terminal 104, and transmit both payload and other types of data overcommunication system 100. Wireless access device can communicate withnetwork 101 through a wireless connection withbase station 102.Wireless access device 103 can contain a buffer, or any kind of practicable storage device, to store data received fromsubscriber terminal 104, and can contain a processor that is capable of determining whether data is present in the buffer, and how much data is in the buffer. The processor can also transmit as request for traffic channels to carry payload data. -
Base station 102 can send and receive data to and from bothwireless access device 103 andnetwork 101.Base station 102 can receive and process requests for channel assignment, and can assign traffic channels for payload data transmission betweenbase station 102 andwireless access device 103,Base station 102 can also send and receive a release message, thereby deconstructing the assigned traffic channels after the data is sent or received, respectively. - In one embodiment, of the present invention, there are at least two distinct network-communication modes.

The network connection has now returned to idle mode. If there is more data to be sent from wireless access device to base station, or from base station to wireless access device, then an active mode is entered in which traffic channels are gain assigned and payload data is again transmitted. Once this data is transmitted, the traffic channels are released, and the system again enters an idle mode. Thus, traffic channels are not assigned until some amount of data is present. In one embodiment of the present invention, channels are allocated on a per-subscriber basis. Thus, once traffic channels are requested, all of the allocated traffic channels can be assigned to carry transmitted data.

This can be done by sendingwireless access device 103 an explicit message over a forward control or non traffic channel, thereby creating or constructing the traffic channels. Alternatively, although not shown,base station 102 can simply create or construct the traffic channels based on the request without sending an explicit grant. - Once the traffic channels are constructed,
wireless access device 103 can transmit payload data to the base station atstep 203, the payload data ultimately intended for to network. Once the payload data is sent, then atstep 204,wireless access device 103 can send a release, prompting the base station to release the traffic channels. The system is now in idle mode. - If
base station 102 has data to transmit towireless access device 103, for example, a web page in response to a URL received from the wireless access device, then in one embodiment of the present invention,base station 102 can send a message over a forward control or non-traffic channel towireless access device 103 that a number of traffic channels has been assigned atstep 205. Payload data can be sent over the traffic channels atstep 206, and the channels are released at step 207, placing the system back in idle mode. - In another embodiment of the present invention,
step 205 does not include a message towireless access device 104 that a number of traffic channels has been assigned. Rather, in this step, traffic channels are simply assigned, and then payload data is transmitted over the assigned channels atstep 206. - As discussed above, the system can include a heartbeat mode in which low-bandwidth timing data is transmitted over an control or non-traffic channel. This heartbeat mode can take the place of the idle mode.

FIG. 3 is a flow chart depicting a method of practicing an embodiment of the present invention. At step 301, the system is in idle mode. Although not shown, the system can instead be in a heartbeat mode. Atstep 302, it is determined whether payload data is present. If payload data is present, then atstep 303, a number of traffic channels are requested from a base station, Once the traffic channels are assigned, the payload data is transmitted over the requested channels atstep 304. The channels are then released, and the system returns to idle mode. In one embodiment of the present inventions a release message can be sent after the payload data is transmitted. - The constructed traffic channels can be one or many radio frequency channels, and the payload-data transmission can be code division multiple access (CDMA) transmission
