The roaming enablement service can identify preferred services of the wireless station and mediate automated negotiations between the access point and a service provider to determine whether the access point may provide a service from the service provider. Upon successful negotiations, the brokerage service can enable the access point to provide access to the preferred services. ## Claims ### Claim 1 A process including: a mobile wireless station encoding in a service set identifier (SSID) field of a probe request a unique user identifier that an enablement service assigned to the mobile wireless station; operating an access point of a wireless network to: receive the probe request from the mobile wireless station in an area of the access point; in response to the probe request, communicate to the enablement service a service request containing information extracted from the probe request and identifying the mobile wireless station; receive in response to the service request service information identifying a service associated with the mobile wireless station; and use the service information to enable the mobile wireless station to contact the service through the access point, and the enablement service brokering between an operator of the wireless network and a service provider providing the service an agreement that controls terms under which the wireless network provides access to the service, where the brokering occurs before the mobile wireless station completes connection to the access point. ### Claim 2 (depends on 1) The process of claim 1, further comprising the enablement service identifying the service by querying a database of services that are associated with mobile wireless stations. ### Claim 3 (depends on 2) The process of claim 2, further comprising the enablement service using a MAC address provided in the service request in identifying the service. ### Claim 4 (depends on 2) The process of claim 2, further comprising the enablement service using an identifier provided in the service request in identifying the service, wherein the identifier is in the probe request that the access point received, and the access point included the identifier in the service request. ### Claim 5 (depends on 1) The process of claim 1, wherein the access point comprises a Passpoint device. ### Claim 6 (depends on 5) The process of claim 5, wherein the mobile wireless station is a second Passpoint device. ### Claim 7 A process comprising: registering a mobile wireless station at a roaming enablement service, wherein registration associates the wireless station with a service; configuring the mobile wireless station to encode a user identifier in a service set identifier (SSID) field of initial probe requests sent upon encountering wireless networks, wherein the enablement service associated the user identifier with the wireless station during the registering of the mobile wireless station; the enablement service receiving the user identifier of the mobile wireless station from an access point that determined the user identifier from an initial probe request from the mobile wireless station; the enablement service using the user identifier to identify the service associated with the wireless station; the enablement service brokering between an operator of a wireless network including the access point and a service provider providing the service an agreement that controls terms under which the wireless network provides access to the service, where the brokering occurs before the mobile wireless station completes connection to the access point; and the access point receiving from the enablement service information that enables the access point to respond to the initial probe request and provide the mobile wireless station with a connection to the service. ### Claim 8 (depends on 7) The process of claim 7, wherein the mobile wireless station is a Passpoint device. ### Claim 9 A wireless access point comprising: a transceiver to receive probe requests from wireless stations; and a hardware executing bootstrap module that upon receipt of an initial probe request from a wireless station, determines a unique user identifier that was encoded in a service set identifier (SSID) field of the probe request and generates a service request to a roaming enablement service, wherein: the service request includes information that is determined from the initial probe request and identifies the wireless station; the bootstrap module uses a response from the roaming enablement service to identify a service associated with the wireless station and to seek enablement of the service for connection of the wireless station; and the roaming enablement service brokers an agreement between an operator of the wireless access point and a service provider providing the service, the agreement controlling terms under which the operator provides access to the service, where brokering the agreement occurs before the mobile wireless station completes connection to the wireless access point. ### Claim 10 (depends on 9) The wireless access point of claim 9, wherein the information that the bootstrap module includes in the service request comprises a MAC address extracted from the initial probe request. ### Claim 11 (depends on 9) The wireless access point of claim 9, wherein the access point is a Passpoint device.
