Wireless network service transaction protocol

摘要

A mobile device may retrieve service information about a network prior to associating with the network. Utilizing an advertisement protocol to transmit service query messages, a mobile device may receive service query responses from a network that identify the services available prior to establishing network capability. In other words, the messaging is prior to the exchange of any authentication parameters between the device and the network as well prior to the establishment of a recognized session between the device and the network.
