Abstract

Multiple-configuration communication apparatus includes: a communication device (130) simultaneously maintaining at least a first and a second channel; a storage device (114, 116, 118) storing a plurality of communication configurations; and a configuration controller (120) determining a first time frame and during the first time frame, selecting a first communication configuration of the plurality of communication configurations and controlling the communication device to configure itself to the first communication configuration to at least one of transmit and receive information over the first channel, and determining a second time frame that is different from the first time frame and during the second time frame, selecting a second communication configuration of the plurality of communication configurations, and controlling the communication device to configure itself to the second communication configuration to at least one of transmit and receive information over the second channel.

Claims

1. Multiple-configuration communication apparatus comprising:

a communication device comprising a single transceiver configured for simultaneously maintaining at least a first channel within a first wireless network and a second channel within a second different wireless network;

a storage device coupled to the communication device for storing a plurality of communication configurations; and

a configuration controller coupled to the communication device, the communication controller configured for;

while simultaneously maintaining the first and second channels, also;

determining a first time frame and during the first time frame, selecting a first communication configuration of the plurality of communication configurations and controlling the communication device to configure itself to the first communication configuration to at least one of transmit and receive information over the first channel; and

determining a second time frame that is different from the first time frame and during the second time frame, selecting a second communication configuration of the plurality of communication configurations, and controlling the communication device to configure itself to the second communication configuration to at least one of transmit and receive information over the second channel.

2. The communication apparatus of claim 1, wherein the communication apparatus comprises one of a subscriber unit and a base station.

3. The communication apparatus of claim 1 further comprising a first information path coupled to communication device and at least a second information path coupled to the communication device, wherein the configuration controller comprises:

a first portion that selects the first information path during the first time frame and that selects the second information path during the second time frame; and

a second portion comprising a single hardware abstraction layer that determines the first time frame based on at least a first parameter associated with the first channel and determines the second time frame based on at least a second parameter associated with the second channel to enable the first and second channels to be simultaneously maintained.

4. The communication apparatus of claim 3, wherein the first parameter is a first inactive mode associated with the first channel and the second parameter is a second inactive mode associated with the second channel.

5. The communication apparatus of claim 1, wherein the first and second communication configurations are in accordance with a wireless protocol.

6. The communication apparatus of claim 5, wherein the wireless protocol is an 802.11 wireless protocol.

7. The communication apparatus of claim 6 further comprising a first Medium Access Control (MAC) engine coupled to the communication device and associated with the first communication configuration and a second MAC engine coupled to the communication device and associated with the second communication configuration.

8. The communication apparatus of claim 7, wherein the first and second MAC engines each comprise an upper MAC portion implemented in software and a lower MAC portion implemented in hardware and coupled between the upper MAC portion and the communication device.

9. The communication apparatus of claim 1, wherein the communication device further comprises an antenna operatively coupled to the transceiver.

10. A method for use in multiple-configuration communication apparatus, the method comprising the steps of:

establishing and simultaneously maintaining a first channel within a first wireless network and at least a second channel within a second different wireless network, using a communication device comprising a single transceiver; and

while simultaneously maintaining the first and second channels, also;

determining a first time frame and during the first time frame, selecting a first communication configuration of a plurality of communication configurations stored in the communication apparatus, controlling the communication apparatus to configure itself to the first communication configuration and at least one of transmitting and receiving information over the first channel; and

determining a second time frame that is different from the first time frame and during the second time frame, selecting a second communication configuration of the plurality of communication configurations, controlling the communication apparatus to configure itself to the second communication configuration and at least one of transmitting and receiving information over the second channel.

11. The method of claim 10, wherein the first and second time frames are determined using a scheduling algorithm based on at least a first parameter associated with the first channel and a second parameter associated with the second channel.

12. The method of claim 11, wherein the first parameter is a first inactive mode associated with the first channel and the second parameter is a second inactive mode associated with the second channel.

13. The method of claim 10, wherein selecting a first communication configuration comprises selecting a first Medium Access Control (MAC) engine, and selecting a second communication configuration comprises selecting a second MAC engine.

14. The method of claim 10, wherein selecting a first communication configuration comprises selecting a first information path, and selecting a second communication configuration comprises selecting a second information path.

15. The method of claim 10, wherein the first communication configuration is associated with a first wireless protocol and the second communication configuration is associated with a second wireless protocol.

17. The method of claim 10 further comprising the step of queuing information transmitted from and received to the communication apparatus over the first and second channels independent of determining the first and second time frames.

18. A processor readable storage medium containing processor readable code for programming a processor to perform a method for use in multi-configuration communication apparatus, the method comprising the steps of:

establishing and simultaneously maintaining a first channel within a first wireless network and at least a second channel within a second different wireless network, using a communication device comprising a single transceiver; and

while simultaneously maintaining the first and second channels, also;

determining a first time frame and during the first time frame, selecting a first communication configuration of a plurality of communication configurations stored in the communication apparatus and controlling the communication apparatus to configure itself to the first communication configuration to at least one of transmit and receive information over the first channel; and

determining a second time frame that is different from the first time frame and during the second time frame, selecting a second communication configuration of the plurality of communication configurations, and controlling the communication apparatus to configure itself to the second communication configuration to at least one of transmit and receive information over the second channel.
