摘要： A switchable transformer architecture is disclosed. The switchable transformer includes a primary winding, a secondary winding, and a tertiary winding, in which either the secondary winding or the tertiary winding establish a signal path to the primary winding, based on the position of switches, enabling transmission to either of two blocks sharing the transformer. The transformer architecture achieves high isolation between sharing blocks and low loss on the signal path.

摘要： The present invention proposes a device and method for detecting the channel state. The detecting device first monitors a channel within a predetermined duration so as to receive a plurality of signals transmitted on the channel, and then determines whether part of the plurality of signals possess periodicity. If part of the plurality of signals possesses periodicity, then the detecting device determines that the channel is interfered. Even if there is no or less data traffic over one or more wireless networks which occupy the channel, the detecting device and method provided by the present invention are capable of detecting the existence of the one or more wireless networks, and determine that the channel is interfered, so as to avoid potential interference. In addition, the cost to detect whether a channel is interfered will be reduced effectively by using the detecting device and the detecting method according to embodiments of the present invention.

摘要： In one embodiment, packet flows are distributed among groups, such as, but not limited to, queues or links. For example in the context of a bundled interface in which multiple links appear as a single logical interface on each of the sender and receiver, packet flows are distributed among these multiple links by the sender. When one or more links become unavailable, packet flows of the affected links are reassigned to other active links, while packet flows assigned to the unaffected links remain associated with the same link in contrast to prior systems which do not attempt to preserve prior associations between packet flows and links. By maintaining these associations, the receiver of the packets does not need to adjust to the different arrival links of packet flows.

摘要： The present invention takes the advantage of the WLAN resources in hotspots for voice and data connections and enables seamless handover between WWAN and WLAN and vice versa. This allows two users in the hotspots to communicate with each other by making a voice over IP (VoIP) or video call, 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 has wireless wide area network (WWAN) and wireless local area network (WLAN) interfaces. The 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.
