1. A method for establishing a tunnel direct link setup (TDLS) session between a first TDLS device and a second TDLS device, the method comprising:

  • sending, from the first TDLS device to the second TDLS device, a TDLS discovery request;

    in response to receiving, at the first TDLS device from the second TDLS device, a response to the TDLS discovery request, sending a TDLS setup request from the first TDLS device to the second TDLS device;

    in response to receiving, at the first TDLS device from the second TDLS device a response to the TDLS setup request;

    (i) sending a TDLS setup confirmation from the first TDLS device to the second TDLS device;

    (ii) establishing the TDLS session between the first TDLS device and the second TDLS device; and

    (iii) persistently storing, at the first TDLS device, information associated with the second TDLS device, wherein the information is persistently stored at the first TDLS subsequent to establishment of the TDLS session between the first TDLS device and the second TDLS device; and

    providing the persistently stored information to a third TDLS device sufficient to enable the third TDLS device to establish a TDLS session with the second TDLS device without performing TDLS discovery.
