摘要： Apparatuses and methods are disclosed herein for implementing dormant mode with paging in a WLAN. Power savings in the computing device and reduction in traffic across the network are achieved by requiring a computing device to inform the WLAN of its location only when it crosses a paging area boundary or is to receive IP traffic. Dormant mode with paging is implemented in a protocol that supports dormant functionality and paging functionality but does not itself provide methods or standards for implementing such functionality, such as the IEEE 802.11. The methods and apparatuses disclosed herein provide the methods needed to implement dormant mode with paging in such a protocol. Generally, the methods and apparatuses for implementing dormant mode with paging basically include (1) establishing paging areas; (2) communicating access group information to a computing device; and (3) locating a computing device.

摘要： A method and communication system for supporting dormant mode are described. In one embodiment, the communication system comprises a wireless station operable in a power savings mode and group of access points. Each group of access points comprises one or more access points with at least one group of access points having at least two access points. Ranges for the one or more access points in each of the groups define a paging area for each group, wherein one access point uses a paging channel for paging the wireless station when the wireless station is in the power savings mode and is in the paging area associated with the one access point. The wireless station performs a handoff procedure when the one access point is not in the same group of access points as the access point associated with the wireless station prior to the wireless station entering the power savings mode and does not perform a handoff procedure when the one access point is in the same group of access points as the access point associated with the wireless station prior to the wireless station entering the power savings mode.

摘要： A method and a system discover a wireless LAN network for a multi-mode handset in a power-efficient way. The method extends stand-by time for the cellular and wireless LAN multi-mode handset, taking advantage of that fact that the cellular interface demands less energy from the battery than the wireless LAN (WLAN)-based interface in such a handset. The method therefore uses the cellular interface as an always-on proxy for the wireless LAN interface to receive the initial packets of a communication session, and uses the initial packet or packets to activate the handset's interface with the wireless LAN.

摘要： A method of coordinating the handoff of a mobile carrier between a first access network and a second access network. The method including establishing a contract between a user of a mobile carrier and a hyper operator and attempting a hand off from a first access network that the mobile carrier is currently operating within to a second access network, wherein the attempting includes authenticating at the hyper operator only that the user may have access to the second access network via the contract. Handing off to the second access network if the authenticating is successful.

摘要： Active scanning method in a wireless network for fast determining available access points (106, 806) using inter-AP (Access Point) communication is described. In the scanning method, a mobile station (102, 802) sends Probe Request for Proxy frame to the current AP (104, 804) serving the mobile station (102, 802). In response to the Probe Request for Proxy frame, the current AP (104, 804) send Proxy Probe Request packet to the appropriate APs (106, 806). In response to the Proxy Probe Request packet, the neighbor APs (106, 806) send Probe Response frame to the mobile station (102, 802) on its operating channel. Since the mobile station (102, 802) moves to the channel being examined after sending the Probe Request for Proxy frame, it receives the Probe Response frame if it is in the coverage area of the neighbor AP (106, 806). The content of Probe Response frame provides the mobile station (102, 802) with the information to be used in handoff decision and network join procedures. Thus, the mobile station (102, 802) neither has to move to the channel to be examined nor send Probe Request frame on that channel. This enables active scan to be initiated even when the neighbor AP (106, 806) is operating in PCF (Point Coordination Function) and the network is in CFP (Contention Free Period), during which unassociated mobile stations (including the scanning mobile station) cannot send packets.

摘要翻译： 描述了使用AP（接入点）通信来快速确定可用接入点（106,806）的无线网络中的主动扫描方法。 在扫描方法中，移动站（102,802）向服务于移动站（102,802）的当前AP（104,804）发送用于代理帧的探测请求。 响应于针对代理帧的探测请求，当前AP（104,804）向适当的AP发送代理探测请求分组（106,806）。 响应于代理探测请求分组，相邻AP（106,806）在其操作信道上向移动台（102,802）发送探测响应帧。 由于移动站（102,802）在发送代理探测请求帧之后移动到被检查的信道，所以如果它在邻居AP（106,806）的覆盖区域内，它接收探测响应帧。 探测响应帧的内容为移动台（102,802）提供要用于切换决策和网络连接过程的信息。 因此，移动台（102,802）既不必移动到要检查的信道，也不在该信道上发送探测请求帧。 即使当相邻AP（106,806）在PCF（点协调功能）中操作并且网络处于CFP（无争用周期））时，也可以启动主动扫描，在此期间，未关联的移动站（包括扫描移动站） 无法发送数据包。

摘要： A method and a communication system including femtocells within a macrocell efficiently manage interference between the different femtocells, and between each femtocell and a macrocell. An efficient frequency assignment scheme for the femtocells minimizes interference between a femtocell and a macrocell and among different femtocells using a spectrum-sensing technique carried out by the femtocells. The frequency assignment scheme selects a suitable channel from a set of candidate channels and ensures that the femtocell has an acceptable coverage area even when it is close to the macrocell base station (BS). The frequency assignment scheme favors a co-channel implementation to take advantage of the hand-off and cell search characteristics of the co-channel implementation. In one embodiment, a joint power control and frequency band assignment technique is used, which partitions the coverage area of the macrocell into an inner region, a power control region, and an outer region. Depending on a femtocell's location, it is assigned a certain power level and a frequency band. Power control may be used within the power-control region while, in the other regions, a fixed transmission power may be used.
