Abstract

A system and methods (300, 500) are disclosed for enabling communications between a communication device and a wireless access point. A system that incorporates teachings of the present disclosure may include, for example, a multimode communication device (MCD) (106) having a controller (214) for managing operations of a multimode wireless transceiver (202) supporting communications on a plurality of wireless access technologies (103). The controller can be programmed to transmit (324) to a network management system (NMS) (100) over a first wireless access technology a request for configuration information associated with a wireless access point, receive (326) the configuration information from the NMS, and enable (320) communications with the wireless access point over a second wireless access technology according to the configuration information. Embodiments for the NMS are also disclosed.

communicate with the wireless access point over the first wireless access technology according to the configuration information.

2. The MCD of claim 1, comprising a user interface (UI) for exchanging messages with the end user of the MCD, wherein the controller manages operations of the UI and is programmed to receive from the end user the request for configuration information associated with the wireless access point.

3. The MCD of claim 2, comprising a global positioning system (GPS) receiver, wherein the controller is programmed to:

conserve energy while the MCD is out of a communication range of the wireless access point;

monitor a location of the MCD;

transmit the location of the MCD to a network management system (NMS);

receive an indication from the NMS that the MCD is near the wireless access point according to the location of the MCD;

enable scanning in response to said indication.

4. The MCD of claim 2, wherein the controller is programmed to:

conserve energy while the MCD is out of a communication range of the wireless access point;

receive an indication from an NMS that the MCD is near the wireless access point; and

enable scanning in response to said indication.

5. The MCD of claim 1, wherein the request comprises an identifier associated with the MCD for enabling the NMS to cross-reference the configuration information with said identifier.

6. The MCD of claim 1, wherein the configuration information comprises a service set identifier (SSID), and one or more encryption keys, and wherein the controller is programmed to transmit the SSID and one or more encryption keys to the wireless access point for enabling communications therewith.

7. The MCD of claim 1, wherein the configuration information is received over one among the second wireless access technology and a third wireless access technology, and wherein the second wireless access technology comprises a circuit-switched channel, and wherein the third wireless access technology comprises a packet-switched channel.

8. The MCD of claim 1, wherein the configuration information is received in a short message system (SMS) message, and wherein the controller is programmed to retrieve the configuration information from the SMS message.

9. The MCD of claim 1, comprising a global positioning system (GPS) receiver, wherein the controller is programmed to include a location of the MCD in the request for enabling the NMS to identify the wireless access point and its corresponding configuration information.

10. The MCD of claim 1, wherein the controller is programmed to transmit to the NMS over the second wireless access technology subsequent requests for configuration information associated with other wireless access points, each of the subsequent requests being in response to a prompt by the MCD provided to an end user of the MCD.

11. A network management system (NMS), comprising:

a controller for managing operations of a communications interface for exchanging messages with multimode communication devices (MCDs) capable of accessing a plurality of wireless access technologies, wherein the controller is programmed to;

receive from an MCD over a first wireless access technology a request for configuration information associated with a wireless access point;

monitor a location of the MCD;

transmit a vicinity indication to the MCD when it is near the wireless access point for enabling in the MCD a process for scanning said wireless access point over a second wireless access technology;
