Abstract

A channel scanning method and system at an MP within a mesh network associated with a local network are provided. A MAP sends a local management frame including information about a mesh network on an allocated local channel and sends a mesh management frame on a mesh channel indicated by the mesh network information. An MP scans a plurality of channels including the local channel and the mesh channel in an order of channels numbers, receives the local management frame by scanning the local channel, and receives the mesh management frame by scanning the mesh channel based on the mesh network information of the local management frame.

Claims

1. A channel scanning method at a mesh point (MP) within a mesh network associated with a local network, comprising:

receiving a local management frame used in a local network;

detecting information about a mesh network from the local management frame; and

receiving a mesh management frame used in the mesh network by scanning a mesh channel indicated by the information about the mesh network.

2. The channel scanning method of claim 1, further comprising upon receiving the mesh management frame, discontinuing scanning of other channels.

3. The channel scanning method of claim 1, wherein the local management frame comprises a Local Probe Response message in response to a Probe Request message broadcast by the MP, and the mesh management frame comprises a Mesh Probe Response message in response to the Probe Request message.

4. The channel scanning method of claim 1, wherein the mesh network information comprises an indication of a number of a mesh channel carrying a mesh management frame from a neighbor MP in the mesh network.

5. A channel scanning method in a mobile access network, comprising:

sending a local management frame comprising information about a mesh network on an allocated local channel by a mesh access point (MAP);

sending a mesh management frame on a mesh channel indicated by the mesh network information by the MAP;

scanning a plurality of channels comprising at least one of the local channel and the mesh channel in an order of channel numbers by a mesh point (MP);

receiving the local management frame by scanning the local channel by the MP; and

receiving the mesh management frame by scanning the mesh channel based on the mesh network information of the local management frame by the MP.

6. The channel scanning method of claim 5, further comprising upon receiving the mesh management frame, discontinuing scanning of the other channels by the MP.

7. The channel scanning method of claim 5, wherein the local management frame comprises a Local Probe Response message that the MAP sends in response to a Probe Request message broadcast by the MP.

8. The channel scanning method of claim 7, wherein the mesh management frame comprises a Mesh Probe Response message that the MAP sends in response to the Probe Request message.

9. A channel scanning system in a mobile access network, comprising:

a mesh access point (MAP) for sending a local management frame comprising information about a mesh network on an allocated local channel and sending a mesh management frame on a mesh channel indicated by the mesh network information; and

a mesh point (MP) for scanning a plurality of channels comprising the local channel and the mesh channel in an order of channel numbers, receiving the local management frame by scanning the local channel, and receiving the mesh management frame by scanning the mesh channel based on the mesh network information of the local management frame.

10. The channel scanning system of claim 9, wherein upon receiving the mesh management frame, the MP discontinues scanning of the other channels.

11. The channel scanning system of claim 9, wherein the local management frame comprises a Local Probe Response message that the MAP sends in response to a Probe Request message broadcast by the MP.

12. The channel scanning system of claim 11, wherein the mesh management frame comprises a Mesh Probe Response message sent by the MAP in response to the Probe Request message.
