Base station initiated proximity service discovery and connection establishment
First Claim
1. A method of establishing a connection between a first device and a second device, comprising:
- operating, by the first device, as an access point for a wireless infrastructure network;
broadcasting, by the first device, an advertisement invitation within a management frame over the wireless infrastructure network, wherein the advertisement invitation requests transmission of advertisements regarding services offered by other devices;
receiving a response to the advertisement invitation from the second device, wherein the response indicates that the second device offers at least a particular type of service, and wherein the second device is a station device on the wireless infrastructure network;
determining, by the first device, that the first device is to access the particular type of service offered by the second device;
in response to the determination, sending, by the first device, a connection invitation within another management frame over the wireless infrastructure network, wherein the connection invitation requests that the second device initiate a connection to the first device via the wireless infrastructure network;
receiving, by the first device, a request from the second device for the second device to connect to the first device via the wireless infrastructure network;
accepting, by the first device, the request from the second device; and
establishing, the connection between the first device and the second device.

Abstract
The normal roles of wireless stations and wireless access points in initiating the establishment of wireless connections may be reversed without the need for changes in the network interfaces for either the station or access point device. This capability may be used to allow wireless devices acting as access points, but on which service clients operate, to initiate the establishment of a connection with a station, on which a wireless service provider operates. Discovery of services between wireless devices can be provided prior to establishing a connection between the devices. A service client device providing access point functionality may broadcast an invitation for service advertisements and then receive service advertisements from relevant service providers acting as wireless stations. An information element may be included as part of periodically broadcast administrative messages to wirelessly convey an invitation for service advertisements. In response to a service advertisement, the access point may send to the wireless station an invitation to connect, prompting the wireless station to begin to establish a connection according to a wireless communication protocol.

10. A system for connecting to an access point of an infrastructure mode wireless network, comprising:
a memory and a processor that are respectively configured to store and execute instructions, including instructions for; receiving, by a second device, a connection invitation within a management frame that was transmitted by a first device over an infrastructure mode wireless network, wherein the connection invitation requests that the second device initiate a connection to the first device, wherein the first device is an access point for the infrastructure mode wireless network, wherein the second device is operable as a station on the infrastructure mode wireless network, and wherein the connection invitation was transmitted by the first device in response to a determination by the first device that the first device is to access a service provided by the second device; and in response to the received connection invitation, establishing, by the second device, a connection to the first device through the infrastructure mode wireless network. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A article of manufacture having instructions stored therein for causing a first device to perform operations including:
-
operating, by the first device, as an access point for a wireless infrastructure network; in response to detection of a service provided by a second device, sending, by the first device, a connection invitation within a management frame over the wireless infrastructure network, wherein the connection invitation requests that the second device initiate a connection to the first device via the wireless infrastructure network while the second device is operating on the wireless infrastructure network as a station device; receiving, by the first device, a request from the second device for the second device to connect to the first device via the wireless infrastructure network; and establishing, the connection between the first device and the second device. - View Dependent Claims (18, 19, 20, 21)
