1. A method comprising:
- receiving from a first device a short request via a network, the short request associated with one or more predetermined information elements;
in response to receiving the short request, sending a generic wrapper information element that includes the one or more predetermined information elements;
receiving from the first device a standard-length request, the standard-length request including;
a plurality of identifiers identifying a plurality of information elements not included in the generic wrapper information element, anda plurality of indicators, each indicator indicating whether a corresponding identified information element is to be sent to the first device if the corresponding identified information element is unchanged since previously sent to the first device; and
in response to receiving the standard-length request, sending a non-generic wrapper information element that conditionally includes each of the identified information elements based at least in part on its corresponding indicator.

Abstract
A method includes detecting, by a first device, a beacon sent from a second device. The beacon is associated with an ad-hoc wireless network. In response to detecting the beacon, the first device sends to the second device a request for management information associated with the ad-hoc wireless network. The request identifies at least a first information element associated with at least a first portion of the management information and a second information element associated with at least a second portion of the management information. The method further includes receiving from the second device a first wrapper information element that includes at least the first information element.
