Abstract

Systems and methods for communicating in a wireless communication system are described. Various processes for reducing the initial link set up time are described. In aspect a method in a wireless communication system is provided. The method includes transmitting two or more network domain identifiers from an access point, each of the network domain identifiers being associated with a respective network service. The method further includes receiving an access request message for establishing the network service associated with at least one of the transmitted network domain identifiers.
