    • The present invention takes the advantage of the wireless local area network (WLAN) resources in hotspots for voice and data connections and enables seamless handover between wireless wide area network (WWAN) and WLAN and vice versa, thus achieving cost savings for the end users and WWAN resources savings for the wireless operators. According to one embodiment of the invention, a mobile terminal having WWAN and WLAN interfaces establishes a WWAN call with a called mobile terminal via a WWAN. If a WLAN is present, the mobile terminal sends a handover request together with its network address to the called mobile terminal, using a short message service (SMS) technique or a watermarking technique, for initiating a WLAN call with the called mobile terminal via a WLAN. After the WLAN call is established with the called mobile terminal, the mobile terminal releases the WWAN call.
    • 本发明利用无线局域网(WLAN)资源在热点进行语音和数据连接,并实现无线广域网(WWAN)与WLAN之间的无缝切换,反之亦然,从而实现最终用户的成本节约, WWAN资源节省无线运营商。 根据本发明的一个实施例,具有WWAN和WLAN接口的移动终端通过WWAN与被叫移动终端建立WWAN呼叫。 如果存在WLAN,则移动终端使用短消息服务(SMS)技术或水印技术将与其网络地址一起的切换请求发送到被叫移动终端,以通过经由呼叫的移动终端发起WLAN呼叫 WLAN。 在与被叫移动终端建立WLAN呼叫之后,移动终端释放WWAN呼叫。

    • Apparatus and methods for managing communication system resources are disclosed. Based on status information received from a resource itself or from other sources, an operational status of a maintenance resource to perform a predetermined maintenance operation on a target communication system resource, for example, may be determined. Access to use resources in performing operations may also be controlled. Resource access is granted or denied based on an availability status of a resource. Other parameters such as relative priorities of a new request to use a resource and a current operation for which access to use the resource was previously granted may also be used in determining whether to grant access to use a resource. A resource may be reclaimed for a higher priority operation for instance. Redundant or alternate resources may also be identified where a resource is not operational or otherwise not available.
    • 公开了用于管理通信系统资源的装置和方法。 基于从资源本身或其他来源接收到的状态信息,可以确定例如对目标通信系统资源执行预定维护操作的维护资源的操作状态。 还可以控制在执行操作中使用资源的访问。 基于资源的可用性状态授予或拒绝资源访问。 先前已经授权的其他参数,例如使用资源的新请求的相对优先级以及先前被授权访问资源的当前操作也可用于确定是否授予访问以使用资源。 例如,可以为较高优先级的操作回收资源。 冗余或备用资源也可以在资源不可操作或不可用的情况下被识别。

    • A LVDS and TMDS dualfunction transmitter for both LVDS and TMDS output channels is disclosed, including an encoder and a serializer. The encoder encodes twenty eight bits of LVDS signals to thirty bits of TMDS signals. The serializer includes four serializer channels for converting the LVDS signals to a serial signal when a LVDS mode is enabled, or converting the TMDS signals to the serial signal when a TMDS mode is enabled. Wherein a first serializer channel is coupled to seven bits of the LVDS signals and outputting a first pair of differential signals. Second, third and fourth serializer channel are coupled to seven bits of the LVDS signals and ten bits of TMDS signals, and outputting a second, third and fourth pair of differential signals, respectively.

    • A combined transmission unit for TMDS signals and LVDS signals. A first (LVDS) transmission unit includes a set of first input terminals to receive first data, and a second (TMDS) transmission unit includes a set of second input terminals to receive second data. A phase locked loop (PLL) generates a first set of output clock signals to the first transmission unit in a first mode and a second set of output clock signals to the second transmission unit in a second mode according to a mode selection signal. The first and second transmission units are able to transmit the first data to the first and second external input units in the first and second modes respectively, according to the mode selection signal and the first and second sets of output clock signals.
