Embodiment Construction

[0020] For a better understanding of the present invention, a wireless local area network (WLAN) according to an exemplary embodiment of the present invention is provided. Then, call setup is described in connection with an example WLAN, and then a handover procedure is performed within the example WLAN.

[0021] Wireless Local Area Network (WLAN) System

[0022] As mentioned in the Background section, each AP in a conventional WLAN transmits on one of multiple channels, where neighboring APs typically transmit on different channels to reduce out-of-cell interference, or from neighboring cells at the local AP Interference received (eg, from neighboring APs and / or mobile devices served by neighboring APs). APs within a conventional WLAN also typically have different Machine Access Code (MAC) addresses and different Basic Service Set Identifiers (BSSID). As detailed below, a WLAN according to an example embodiment of the present invention includes APs that communicate via the ...

Abstract

A method which generates a polling scheduling according to a plurality of access points and a plurality of mobile devices in a wireless local area network which is operated by the wireless communication protocol, comprising: first, a first polling scheduling is generated, which polls one of the device of a plurality of mobile devices in a first quantity of slot, and the first polling scheduling is configured to facilitate each polling of a plurality of mobile devices not to disturb each other; based on the first polling scheduling, for the first time whether each of a plurality of mobile devices can get polled in the slot which is less than the first quantity of slot and at the same time not disturb each other is guaranteed; if the guaranteeing steps guarantee that each of a plurality of mobile devices can get polled in the slot which is shorter than the first quantity of slot, the second polling scheduling is generated, and the second polling scheduling polls each of a plurality of mobile devices in the second quantity of slot, and the second polling scheduling is the compressed edition of the first polling scheduling which leads the second quantity of slot less than the first quantity of slot.

Description

technical field [0001] Embodiments of the present invention generally relate to a method for generating a polling schedule for a wireless local area network (WLAN), and in particular to a method for generating a polling schedule for polling a mobile device in a WLAN. Background technique [0002] Within a WLAN, mobile devices use an access point (AP), such as a wireless router, to connect to a wired network and communicate with other hosts. APs are typically equipped with an interface to connect to a wired network (eg, via an Ethernet connection), and a wireless interface (eg, IEEE 802.11(b / g), 802.16(d / e), Bluetooth, etc.) to communicate with mobile devices. [0003] The coverage area of ​​an AP operating indoors according to 802.11 is limited to approximately 200 to 300 feet. Additional APs can be used to extend the coverage area. When a mobile device moves from the coverage area of ​​a first AP to a second AP, processing of communications for the mobile device has been ...
