摘要： Techniques are provided for selecting an access point (AP) to communicate with from a plurality of candidate access points (APs) when a wireless communication device (WCD) roams in a wireless local area network (WLAN). The WCD can determine whether a particular link quality metric (e.g., a signal strength indicator value) of a particular preferred access point (that has the highest link quality metric) is greater than an upper threshold. If so, the WCD can then create a preferred candidate list that comprises only preferred access points, and determine whether a current serving access point of the wireless communication device is a preferred access point. If the current serving access point is not a preferred access point, the WCD can initiate a roam to the particular preferred access point that has the strongest link quality metric.

摘要： A network element and method for transferring software content from a radio communication network to a network element includes associating a unique identifier for the element with the content. Content is first transferred to the element. Connectivity between the network and element is then verified. If connectivity is verified after the transfer of content, previous software content within the element is upgraded using the transferred content. Connectivity between the network and element is again verified after the upgrade. If connectivity is not verified after the transfer of the content, the previous software content is restored within the element. The connectivity tests ensure that any upgrade will not leave the network element unable to communicate with the network.
摘要翻译：用于将软件内容从无线电通信网络传送到网络元件的网络元件和方法包括将该元件的唯一标识符与内容相关联。内容首先被转移到元素。然后验证网络和元素之间的连接。如果在传输内容后验证连接性，元素内的先前软件内容将使用传输的内容进行升级。网络和元素之间的连接在升级后再次被验证。如果在传输内容之后没有验证连接性，则在元素内恢复以前的软件内容。连接测试确保任何升级不会使网络元素无法与网络通信。

摘要： Techniques are provided for determining whether a particular Access Point (AP) is to be designated as an Infrastructure Access Point (IAP) or a Backhaul Mesh Access Point (BMAP) based on the connectivity of the particular AP to a network which includes at least one multicast heartbeat message (MCHBM) source. Techniques are provided which can allow an Infrastructure Access Point (IAP) to change its device type to a Backhaul Mesh Access Point (BMAP) device type when the IAP determines that connectivity to the network is lost. Other techniques are provided which can allow a Backhaul Mesh Access Point (BMAP) to change its device type to an Infrastructure Access Point (IAP) device type when the BMAP determines that connectivity to the network is established.

摘要： The disclosure relates to reducing the risk of security breaches in a multi-hop network. A decryption engine can decrypt at least a portion of a first encrypted packet using a first pair-wise transient key (PTK) to generate a first decrypted packet. A processor can then process the first decrypted packet to generate decrypted extracted information (DEI). An Operating System (OS) can receive the DEI from the processor, and then generate a forward message when the first encrypted packet is to be forwarded to the next hop node. The processor can then determine a destination address, a next hop address, and a second PTK associated with the next hop address from a key table. The decryption engine uses the first PTK to decrypt the first encrypted packet, and the encryption engine can use the second PTK to encrypt a first decrypted packet to generate a second encrypted packet.
摘要翻译：本公开涉及降低多跳网络中安全漏洞的风险。解密引擎可以使用第一成对瞬态密钥（PTK）来解密第一加密分组的至少一部分，以生成第一解密分组。处理器然后可以处理第一解密包以产生解密的提取信息（DEI）。操作系统（OS）可以从处理器接收DEI，然后当第一加密分组被转发到下一跳节点时，生成转发消息。然后，处理器可以从密钥表确定目的地址，下一跳地址和与下一跳地址相关联的第二PTK。解密引擎使用第一PTK来解密第一加密分组，并且加密引擎可以使用第二PTK来加密第一解密分组以生成第二加密分组。

摘要： A method and system for secure call Dual-Tone Multi-Frequency (DTMF) signaling includes entering (202) dial string of a telephone number of a destination device, assigning (210, 212) the dial string to a predefined string having a total length that is greater than the dial string such that there will be at least one leading hexadecimal bit in the predefined string length that is not used when the entered dial string is converted to a hexadecimal, converting (214) the dial string to hexadecimal, reversing the order of the hexadecimal, and placing the reversed hexadecimal at the beginning of the predefined string, appending (216) “one” bits to the predefined string length indicating how many nibbles of the predefined string length are unused, if any, and appending the remaining intervening unused bits in the predefined string length to “zero” bits, and sending (226) the encoded string length.

摘要： A method and apparatus for presence state determination at an access point of a station determines whether a station associated with the access point is responsive to the access point to indicate the station is “present” or “not present”. The access point informs a presence server when the station's presence state changes. The presence server does not therefore need to rely on presence handshaking between the presence server and the station.
摘要翻译：用于在站的接入点处的存在状态确定的方法和装置确定与接入点相关联的站是否响应于接入点以指示站“存在”或“不存在”。当站的状态改变时，接入点通知存在服务器。因此，存在服务器不需要依赖于存在服务器和站之间的存在握手。
