Abstract
A particular method includes generating, at a mobile station, a probe request frame and a service discovery request. At least a first portion of the service discovery request may be encapsulated within the probe request frame to form a modified probe request frame. The modified probe request frame may be wirelessly transmitted, for example, to a particular access point or to all access points with range of the mobile station.
Claims40
A method comprising:
- generating, at a mobile station, a probe request frame;
- generating, at the mobile station, a service discovery request;
- determining that the service discovery request exceeds a threshold size;
- parsing the service discovery request into two or more portions;
- encapsulating at least a first portion of the service discovery request within the probe request frame to form a modified probe request frame;
- encapsulating at least one second portion of the service discovery request within a second probe request frame to form a second modified probe request frame;
- and
- wirelessly transmitting both the modified probe request frame and the second modified probe request frame.
5 more elements
An apparatus comprising:
- a transmitter;
- a processor coupled to the transmitter;
- and
- a memory coupled to the processor, wherein the memory stores instructions executable by the processor to:
- generate a probe request frame;
- generate a service discovery request;
- determine that the service discovery request exceeds a threshold size;
- parse the service discovery request into two or more portions;
- encapsulate at least a first portion of the service discovery request within the probe request frame to form a modified probe request frame;
- encapsulate at least one second portion of the service discovery request within a second probe request frame to form a second modified probe request frame;
- and
- cause the transmitter to transmit both the modified probe request frame and the second modified probe request frame.
9 more elements
A non-transitory processor-readable medium comprising instructions that, when executed by a processor, cause the processor to:
- generate a probe request frame;
- generate a service discovery request;
- determine that the service discovery request exceeds a threshold size;
- parse the service discovery request into two or more portions;
- encapsulate at least a first portion of the service discovery request within the probe request frame to form a modified probe request frame;
- encapsulate at least one second portion of the service discovery request within a second probe request frame to form a second modified probe request frame;
- and
- cause a transmitter to transmit both the modified probe request frame and the second modified probe request frame.
