Abstract

Access control techniques enable an access terminal to obtain service through an access point. In some aspects, access control techniques may be used to enable a user (e.g., an owner) of an access point to control whether an access terminal obtains service through the access point. For example, a user may temporarily disable access control at an access point to enable access points that register with the access point while access control is disabled to thereafter be allowed to obtain service through the access point. As another example, a shared secret may be provided to an access terminal whereby, upon presenting the shared secret to an access point, the access terminal is allowed to obtain service through the access point.

Claims
