Abstract: An improved method and system for transmitting a stream of data bytes through a channel (506A, 506b) whose capacity may change during transmission. By utilization of selective regions of sequence number space, the enhanced radio link protocol (RLP) (140, 142, 144) provides the benefits of large byte sequence numbers while transmitting a fraction of the sequence number bits in the majority of over-the-air frames. Frame header sequence numbers are shortened by dividing the byte sequence number by a page size, and by performing a modulo function on the byte sequence number.

Abstract: This disclosure describes audio decoding techniques for decoding audio information that needs to be properly clocked. In accordance with this disclosure, the number of audio samples in decoded audio output can be adjusted to compensate for an estimated error the in decoder clock. That is to say, rather than adjust the decoder clock to synchronize the decoder clock to the encoder clock, this disclosure proposes adding or removing audio samples from the decoded audio output in order to ensure that the decoded audio output is properly timed. In this way, the techniques of this disclosure can eliminate the need for an adjustable or controllable clock at the decoding device, which can save cost and/or allow legacy devices that do not include an adjustable or controllable clock to decode and output audio information that needs to be properly clocked.

Abstract: A method for selectively maintaining compression state and applying a compression technique after a PPP renegotiation on a Um interface of a wireless communicaiton network. A communication device (104) receives packetized data transmitted from a terminal device (102), which is coupled to the communication device via an Rm interface. The communciaiton device determines (S315) whether the received packetized data comprises compressed or uncompressed data. Upon determining that the received packetized data comprises compressed data, the communicaiton device determines (S340) whether connection information exceeds a highest-numbered decompression slot from a plurality of decompression slots on said Um interface. The communciation device sets up (S330) a local decompression slot, int he communicaiton device, which corresponds to the connection information in order to maintain said compressionsate, wherein the local decompression slot is set up in response to determining (S325) that the connection information exceeds the highest-numbered decompression slot. The communication device decompresses (S350) the compressed packetized data when it receives compressed packetized data containing said connection information.

Abstract: A method and system that detects protocol and configuration messages in a PPP packet without having to unframe the entire packet. The method includes a communication device (MT2) that receives a plurality data frames (S306), wherein the communication device is capable of ascertaining the beginning of an information portion (S305) within the received frames. The communications device detects whether the information portion contains configuration information, such as protocol and configuration messages of a predetermined type. In a first embodiment, the detection is achieved by the communication device unescaping (S315) the contents of a plurality of bytes and determining (S325, S330, S335) whether the escaped bytes contains the desired configuration information. In a second embodiment, the communication device determines whether the contents of a particular byte contain the desired configuration information, in escaped or unescaped form, and the communication device continues to sequentially process the bytes within the information portion until the bytes typically containing the desired configuration information are processed.

Abstract: An apparatus (102, 104) for transmitting a stream of information bytes, the apparatus (102, 104) includes a mechanism (604, 618, 638) for receiving/transmitting a message specifying a radio link protocol, RLP, round-trip time, RTT, estimate, and a mechanism (604) for conducting an RLP communication session using said RTT estimate to determine negative acknowledgment, NAK, message timing. A first RLP RTT estimate can be established during service negotiation, and is used to determine NAK message timing in a subsequent RLP communication session. Alternatively, a 3-way handshake is performed for generating a first RTT estimate associated with the first RLP communication session, a second RTT estimate, based on the first RTT estimate, associated with a second RLP communication session is established during service negotiation. The second RLP RTT estimate is used to determine NAK message timing in a subsequent RLP communication session.

Abstract: An improved method and system for determining round-trip time (RTT) during a radio link protocol (RLP) wireless communication link. The RTT estimate is negotiated by both sides of the RLP communication link without the need for the 3-way handshake generally required for RLP synchronization. The method includes techniques used by both sides of the RLP communication link to dynamically update and refine their initial, negotiated RTT estimates.

Abstract: A method for selectively maintaining a compression state and applying a compression technique after a PPP renegotiation on a U m interface of a wireless communication network. A communication device (104) receives packetized data transmitted from a terminal device (102) which is coupled to the communication device via an R m interface. The communication device determines (S315) whether the received packetized data comprises compressed or uncompressed data. Upon determining that the received packetized data comprises compressed data, the communication device determines (S340) whether connection information exceeds a highest numbered decompression slot from a plurality of decompression slots on said U m interface. The communication device sets up (S330) a local decompression slot, in the communication device, which corresponds to the connection information in order to maintain said compressionsate, wherein the local decompression slot is set up in response to determining (S325) that the connection information exceeds the highest-numbered decompression slot. The communication device decompresses (S350) the compressed packetized data when it receives compressed packetized data containing said connection information.
