摘要： 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.

摘要： For Mobile IP supporting inter-technology handoffs, a logical interface is provided at an abstraction layer, which resides between a network layer and a link layer. The logical interface performs processing to provide an interface between the network layer and the link layer, but communicates with physical interfaces instead of directly with the link layer. One physical interface is provided for each communication network (e.g., each radio network of a different wireless technology). Each physical interface performs technology-dependent processing for the associated communication network and communicates with a respective link layer module. Each link layer module performs link layer processing for the associated communication network. The logical interface is associated with one physical interface at any given moment. The logical interface is also associated with an IP address that does not change and is used by IP in the network layer for communication with the multiple communication networks.

摘要： Techniques for minimizing dormant reactivations to receive IPv6 Router Advertisements are described. In a first scheme, a timer is used to trigger a wireless terminal to solicit a Router Advertisement. The timer is set to a threshold time period computed based on the current prefix lifetime. When the timer expires, a Router Solicitation is sent. In a second scheme, after the timer expires, a Router Solicitation is sent whenever the terminal is active. In a third scheme, a Router Solicitation is sent when the timer expires if solicitation is triggered and at any time thereafter whenever the terminal is active. In a fourth scheme, two timers are set to two threshold time periods. After the first timer expires, a Router Solicitation is sent whenever the terminal is active. When the second timer expires, a Router Solicitation is sent if solicitation is triggered by a predefined event or condition regardless of the terminals state.

摘要： A wireless network assigns a single IP address to the wireless device, which assigns this IP address over to a TE2 device coupled to the wireless device. The wireless device derives a private IP address for communication with the TE2 device. The wireless device forwards packets exchanged between the TE2 device and the wireless network using the single IP address. The wireless device exchanges packets with the TE2 device by (1) using the private IP address for outbound packets sent to the TE2 device and (2) performing either address-based routing or packet filtering on inbound packets received from the TE2 device. The wireless device exchanges packets with the wireless network by (1) using the single IP address for outbound packets sent to the wireless network and (2) performing packet filtering on inbound packets received from the wireless network.

摘要： A majority of the IP packets sent from an IP network over a wireless network to a mobile station which is tethered to an electronic device, such as a laptop computer, are destined for applications running on the electronic device. The embodiments are for snooping and filtering incoming IP packets to delineate only those packets destined for mobile station applications, which greatly improves the processing efficiency of the mobile station. In particular, the CID fields of TCP/IP packets utilizing Van Jacobson compression techniques are snooped and filtered.

摘要： Techniques for avoiding data loss and reducing registration overhead in a wireless packet data communication system are disclosed. In one embodiment, a mobile station (170) adds each connection to a connection list (430) following registration with the PCF (130). The mobile station need not reregister a connection included in the connection list when it again enters the PCF's coverage area. In another embodiment, a PDSN (110) maintains a connection table (330), with one or more connections for each mobile station. The PDSN transmits data to the mobile station along one of the connections. In yet another embodiment, a PDSN transmits on an active connection, if one exists. In yet another embodiment, connections in a connection list or connection table are removed when a corresponding inactivity timer (320) expires. Various other embodiments are also presented. Benefits include allowing mobile stations to travel between PCFs without re-registering, which reduces registration overhead and increases system capacity, and avoidance of data loss from network initiated data directed to a mobile station, resulting in timely delivery of the data and reduction of system resources allocated to retransmission of data.
摘要翻译：公开了一种用于在无线分组数据通信系统中避免数据丢失和减少注册开销的技术。在一个实施例中，移动站（170）在与PCF（130）对齐之后，将每个连接添加到连接列表（430）。当移动台再次进入PCF的覆盖区域时，不需要重新注册包括在连接列表中的连接。在另一个实施例中，PDSN（110）维护连接表（330），其中每个移动站具有一个或多个连接。 PDSN沿着连接之一向移动台发送数据。在另一个实施例中，PDSN在活动连接上发送，如果存在的话。在另一个实施例中，当相应的不活动定时器（320）到期时，连接列表或连接表中的连接被去除。还提出了各种其它实施例。优点包括允许移动台在PCF之间行进而无需重新注册，从而减少注册开销并增加系统容量，并避免从指向移动台的网络启动数据丢失数据，从而及时传送数据并减少系统资源分配给数据重传。

摘要： For quick call setup, terminal A sends to terminal B stuffing sequences for the highest H.223 multiplexer level supported by terminal A and at least one proprietary sequence. The proprietary sequence indicates support for quick call setup and contains video and audio codecs supported by terminal A. Terminal A monitors for stuffing and proprietary sequences sent by terminal B. If terminal A receives a proprietary sequence from terminal B, then terminal A sends an H.245 NonStandard request message containing the information in the proprietary sequence sent to terminal B, video and/or audio capabilities supported by terminal A, and entries for a multiplex table used by terminal A. Terminal A monitors for a NonStandard request message from terminal B, which contains video and audio capabilities and multiplex table entries for terminal B. Terminals A and B are ready to communicate upon each terminal receiving an acknowledgment from the other terminal.

摘要： Communication methods, buffer management methods, communication systems, and communication devices for mobile communications using acknowledgement-based protocols, such as TCP. Communication buffer memory includes free and committed memory, with copies of transmitted messages awaiting acknowledgement stored in committed memory of transmit buffer. Memory controller monitors communication buffer state and, if free memory is less than a memory threshold, controller extracts TCP ACKNUM from a received host message. The TCP ACKNUM acknowledges transmitted message copies having ACKNUMs of lesser ordinality, and memory controller identifies and denominates the committed memory storing acknowledged messages as free memory, potentially avoiding deadlock.
