    Abstract: PROBLEM TO BE SOLVED: To provide a method and system for hard handoff in a broadcast communication system. SOLUTION: When a subscriber station performs the hard handoff between two cells (base stations) where a broadcast stream is not synchronized, a subscriber station receiving a broadcast session in a former broadcast stream acquires a broadcast session in a new broadcast stream and identifies service option information. The subscriber station decodes the identified service option information, acquires a parameter necessary for processing the new broadcast stream and ends the handoff by decoding and outputting the former broadcast stream. The subscriber station uses a latest parameter to decode and output the received broadcast stream. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a method and system for handoff in a broadcast communication system.
    SOLUTION: A subscriber-assisted handoff is impractical in a broadcast communication system due to e.g., a high signaling load or a difficulty to synchronize the broadcast transmission. At the same time, a small number of broadcast channels enable the subscriber station to perform the handoff autonomously. While performing a handoff between broadcast transmissions, a disruption of service occurs due to lack of synchronization between the broadcast transmissions. To reduce the service disruption, upon detecting a need for handoff, the lower layers inform the application layer of the forthcoming handoff. The application layer thus may take measures to reduce or prevent the disruption.

    Abstract: PROBLEM TO BE SOLVED: To provide an interface for a digital wireless telephone system compatible with standard analog wire line FAX machines.
    SOLUTION: In order to establish a source fax interface at a proper rate, a source interface 24a selects an initial data rate from a set of standard fax transmission rates. The source interface 24a sends a message of an unacceptable rate to a source fax machine 18a until the surface fax transmission rate is less than or equal to a data channel rate and a destination fax transmission rate. During fax processing, a destination interface 24b inserts non-printing data (fill bits) if the destination fax transmission rate is larger than the source fax transmission rate.

    Abstract: PROBLEM TO BE SOLVED: To provide an efficient method for detecting delayed data frames in a transport function. SOLUTION: A method for detecting delayed data frames in a transport function includes the steps of comparing a frame sequence counter with a predetermined threshold value (304), detecting a delayed frame if the sequence counter exceeds the threshold value, and processing the detected delayed frame accordingly (306). In an RLP data transport protocol, the delayed frame may be processed as a retransmitted frame. The threshold value may be proportional to the maximum number of frames sent in a given bundle, times the maximum delay, in units of frame intervals, between frames sent simultaneously over the air in the same frame interval.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for reducing transmission delay in a wireless communication system that sends packetized voice and data information. SOLUTION: Interruptions in traffic channels cause loss of synchronization between a header compressor and a header decompressor. Rather than transmitting resynchronization information on a traffic channel, the information dropped by an interruption is retransmitted on a non-traffic channel in parallel with the traffic channel. At a remote station, information from the traffic channel and the non-traffic channel is reassembled before input into the decompressor. Alternatively, the non-traffic channel can be used to send overflow information, so that a higher average data rate is achieved than the average data rate of the traffic channel alone.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for data packet transport in a wireless communication system using an Internet protocol (IP).
    SOLUTION: The method and apparatus are provided for data packet transport in a wireless transmission system supporting broadcast transmissions. A multicast tree is built between nodes through neighboring routers. The multicast tree forms a tunnel through which the broadcast content is transmitted. The broadcast message is encapsulated in an Internet Protocol packet for transmission through the multicast tree. At least one multicast tree is formed between the Internet portion of the system and the wireless portion of the system, such as the Access Network. In one embodiment, an external multicast tree is formed between a content source and a packet data service node, and an internal multicast tree is formed between the packet data service node and a packet control function node.
