Abstract: Systems and methods reduce latency associated with establishing communication on a wireless network. In one aspect, an access point determines interface identifiers for associated stations. Because the access point can ensure interface identifiers are not duplicated across associated stations, the need for duplicate address detection by the stations is reduced. In another aspect, an access point provides domain name system server network address information to a station. By providing the network address information of the DNS server, the need for the station to perform separate signaling to obtain the information is reduced. In another aspect, an access point transmits a mapping of a first station's network address to the first station's medium access control address to one or more associated stations. This may reduce the need for an associated station to perform address resolution signaling when attempting to communicate with the first station.

Abstract translation: 系统和方法减少了在无线网络上建立通信的延迟。 在一个方面，接入点确定关联站的接口标识符。 由于接入点可以确保接口标识符在相关站之间不重复，所以减少了站点重复地址检测的需要。 另一方面，接入点向站点提供域名系统服务器网络地址信息。 通过提供DNS服务器的网络地址信息，减少了站点执行单独信令以获得信息的需要。 在另一方面，接入点将第一台站的网络地址映射到第一台的介质访问控制地址到一个或多个相关站。 当尝试与第一站通信时，这可能减少对相关站执行地址解析信令的需要。

Abstract: Methods, devices, and computer program products for hierarchical time source usage in near-me area network discovery and synchronization are described herein. In one aspect, a method for determining a discovery period using a hierarchy of external timing sources is provided. The method includes receiving an external timing signal from one or more external timing sources, and then using a hierarchy of external timing sources to determine which external timing source to use. The method further provides determining an offset from that external timing source, and using the external timing source and the offset to determine a discovery interval, in which to attempt to locate a near-me area network (NAN), such as a Social-WiFi network.
