摘要： Requests for location fix for a mobile device are received from one or more Location Based Service (LBS) applications. The received requests are queued in a First In First Out (FIFO) queue in the mobile device. Based on information in a first request out of the FIFO queue, the mobile device runs a location engine in a first fix mode to obtain a fix on the location of the mobile device for a response to the first request. While the location engine is running to obtain the fix for the response to the first request, the mobile device analyzes information in a second request in the FIFO queue, to determine a second fix mode for response to the second request. Based on a comparison of the second fix mode to the first fix mode, the mobile device may change the information in the second request to correspond to the first fix mode, before output of the second request from the FIFO queue to the location engine.
摘要翻译：从一个或多个基于位置的服务（LBS）应用程序接收针对移动设备的位置修复请求。接收的请求在移动设备中的先进先出（FIFO）队列中排队。基于来自FIFO队列的第一请求中的信息，移动设备以第一修复模式运行位置引擎，以获得针对第一请求的响应的移动设备的位置的修正。当位置引擎正在运行以获得对第一请求的响应的修复时，移动设备在FIFO队列中的第二请求中分析信息，以确定用于响应于第二请求的第二修复模式。基于第二固定模式与第一固定模式的比较，在从FIFO队列输出到位置引擎之前，移动设备可以将第二请求中的信息改变为对应于第一固定模式。

摘要： A system for determining position of a mobile station is provided. The mobile station is equipped with a GPS receiver for receiving satellite signals from satellites. The system comprises a wireless wide area network (WWAN) configured to provide an acquisition assistance data for use in acquiring the satellite signals by the GPS receiver to the mobile station that is operable in the WWAN. A position determination entity (PDE) is provided to determine position of the mobile station based on the satellite signals received sent from the mobile station and the acquisition assistance data from the WWAN. A wireless local area network (WLAN) provides RF signals to the mobile station when the mobile station enters into a WLAN area. The mobile station determines the position of the mobile station using the WWAN transceiver and the GPS receiver at the time when the mobile station enters into the WLAN area. The MS then uses this position when it is operating in the WLAN and it is requested to provide location by a LBS application or by the emergency 911 calling service.

摘要： Methods and systems for addressing threshold voltage shifts of memory cells. A method includes reading a pattern of data from a first plurality of memory cells, comparing the read of the pattern of data with a known pattern of data using a reference, and if the read of the pattern of data and the known pattern of data do not match, adjusting the reference to find a reference level that results in a matching of a read of the pattern of data and the known pattern of data. Thereafter, trim sector data is read into a second plurality of memory cells using the adjusted reference level.

摘要： When a mobile device receives an incoming call from a telephone number: it identifies a number of digits associated with the telephone number and determines whether the number of digits exceeds a threshold. Upon determining that the number of digits exceeds the threshold, the incoming call is identified as an international call and the telephone number is identified as an international telephone number. The mobile device identifies a reference country from which the international call is originated and stores the international telephone number in association with the reference country in its memory.

摘要： Disclosed examples of secure communications involve generating, by a mobile communication network device, a shared secret data having a length of M units. A first operation on groups of one of N units of a randomly generated base shared secret data and one of a plurality of secret values thereby generates a plurality of first operation results. A second operation on a select plurality of the first operation results generates a plurality of second operation results. The randomly generated base shared secret data can have a length of N units, where N is less than M. The shared secret data is constructed from at least one of the first operation results and the plurality of second operation results.

摘要： To support authentication of a mobile device, an application server obtains an application identifier and password and creates an encrypted value by encrypting a combination of the password and a time-based value. The application server transmits the application identifier and encrypted value over a communication network to the mobile device as a credential, and the mobile device sends the credential over the network to a secure server providing an application assistance service. The secure server independently computes an encrypted value by encrypting the combination of the password and the time-based value. If the encrypted value from the received credential matches the encrypted value computed by the secure server, that server grants access to the assistance service for the mobile device.
摘要翻译：为了支持移动设备的认证，应用服务器获得应用标识符和密码，并通过加密密码和基于时间的值的组合来创建加密值。应用服务器通过通信网络将应用标识符和加密值作为凭证发送到移动设备，并且移动设备通过网络将证书发送到提供应用辅助服务的安全服务器。安全服务器通过加密密码和基于时间的值的组合来独立地计算加密值。如果来自接收到的凭证的加密值与由安全服务器计算的加密值相匹配，则该服务器授予对移动设备的辅助服务的访问权限。

摘要： Automating emergency calls globally involves receiving, from a user and at a mobile device, a number associated with an outgoing call; identifying, at the mobile device, the received number is a first emergency number; and identifying, at the mobile device, a country associated with the first emergency number. The mobile device also identifies a country of operation of the mobile device at a time of receiving the first emergency number. The device then determines whether the country of operation corresponds to the country associated with the first emergency number. Upon determining that the country of operation does not correspond to the country associated with the first emergency number, a second emergency number associated with the country of operation is determined. The mobile device transmits the second emergency number to a wireless network servicing the mobile device, instead of the first emergency number, to initiate the emergency call.
