摘要： A signal comprises a sequence of fields, each field having a synchronization portion and a data portion, a transmitter inserts a pseudonoise (PN) sequence into the synchronization portion of a field for use in identifying a presence of mobile data in the data portion of that field; and transmits the signal. In complementary fashion, a receiver receives the signal and upon detecting the PN sequence in the synchronization portion of the received signal determines whether or not mobile data is in the data portion of that field of the received signal.

摘要： One method involves the steps of causing a message to be sent to a relay network for delivery to a mobile device through one of a plurality of wireless networks coupled to the relay network; receiving, from the relay network, a result message when the mobile device is unavailable to receive the message, the result message comprising a message identifier; maintaining storage of the message in memory accessible by a host server after the result message is received; receiving, from the relay network, a status message which indicates that the mobile device is available to receive the message when the mobile device is available to receive the message; and causing the message to be sent again to the relay network for delivery to the mobile device in response to receiving the status message. During the unavailability, the relay network refrains from maintaining storage of the message.

摘要： An implementation provides a transmitter that separates sequential portions of data in a first set of data by time intervals allowing a power saving mode (1005). The transmitter transmits the sequential portions of data separated by respective time intervals having lengths configured to allow a receiver to enter and exit a power saving mode between receiving sequentially transmitted portions of data from the first set of data (1010). The transmitter separates sequential portions of data in a second set by time intervals that are not of sufficient length to allow a receiver to enter and exit a power saving mode during the time intervals (1015). The second set of data is then transmitted (1020).

摘要： A communications system includes a wireless telephony network and a wireless Local Area Network (LAN), both accessible by a mobile communications device (16). To facilitate transitioning of the mobile communications device to the wireless LAN from the wireless telephony network, the wireless LAN includes a beacon transmitter, which generates a synchronization channel having a pattern unique to the wireless LAN. The Wireless LAN synchronization channel is received at a first receiver in the mobile communications device together with a synchronization channel from the wireless telephony. The wireless LAN synchronization channel enables the mobile communication device to synchronize with, for transitioning to, the wireless LAN.

摘要： The present invention provides an encoding method for skipped macroblocks in a video image comprising the steps of: adding one indication bit into a picture header for indicating a coding mode for skipped macroblocks in a current image; selecting the coding mode for a macroblock type in the current image according to the number of skipped macroblocks, if it is a run_length coding, then setting the indication bit of the picture header as a status indicating a run_length coding, and encoding the macroblock type in the image by the run_length coding mode; if it is a joint coding of the number of skipped macroblocks and the macroblock type, then setting the indication bit of the picture header as status indicating a joint coding and encoding the macroblock type in the image by the joint coding mode of the number of skipped macroblocks and the macroblock type; finally, encoding other data in the current macroblock and writing data into a code stream. The present invention selects the coding mode for skipped macroblocks in video image adaptively, which improves the image encoding efficiency, reduces the cost for transmission and storage, therefore it is a simple and practical technical solution. The present invention can be used validly in both frame encoding and field encoding.

摘要： The present invention discloses a method for obtaining image reference block in a code mode of fixed reference frame number, comprising the steps of: performing motion estimation for each block of a current B frame and obtaining a motion vector MV of a corresponding block of a backward reference frame; discriminating whether the motion vector is beyond a maximum forward reference frame which is possibly pointed by the B frame, if not, then calculating the forward and backward motion vectors in a normal way; if yes, then using the motion vector of the forward reference frame that the B frame can obtain in the same direction to replace the motion vector of the corresponding block in the backward reference, and calculating the forward and the backward motion vectors of the B frame; finally, two image blocks pointed by the final obtained forward and backward motion vectors as the image reference blocks corresponding to the macro block. The present invention solves the possibly appeared problem of un-matching motion vectors, and can guarantee the coding efficiency to the largest extent.
