Abstract: An optical network unit (ONU) interconnected by passive optical network (PON) equipment to an optical line terminal (OLT) is identified using secondary modulation of the optical carrier to impress an identifier of the ONU onto the carrier. This resolves a recurring ONU failure mode detection problem caused by failure of a laser driver that causes the ONU to be stuck in an on state.

Abstract: The present invention provides distributed communication services based on a presence technology platform. Presence messaging and communication techniques allow a variety of communication agents to cooperate with one another to provide distributed services. Essentially, the messaging between the agents is used to facilitate media sessions and update participating devices of state changes bearing on providing the services. In one embodiment, each of the participating devices is associated with a logic entity, referred to as a presentity, which subscribes to notification services for the other participating devices. When a state change occurs on any one of the participating devices, the corresponding presentity notifies the other devices of the state change. As such, each participating device knows the status of the other participating devices via the presentities and can systematically determine when and how to provide services based on its current state and the current state of the other participating devices.

Abstract: The present invention uses a portion of an orthogonal spreading code space in a CDMA spectrum for uplink signaling from a user element to a base station. By assigning the user elements one or more signaling codes, which are orthogonal to those used to spread data, to use for uplink signaling, the present invention significantly reduces interference between signaling channels, and between the data channels and the signaling channels, while supporting additional capacity. The signaling codes may be individually assigned to user elements or assigned to groups of user elements. Further, different length signaling codes may be assigned to the user elements to support different signaling rates depending on Quality of Service (QoS) requirements.

Abstract: The present invention provides a technique for supporting variable bitrate services in an OFDM environment while minimizing the impact of the variations of fading channels and interference. In general, a basic access channel (BACH) is defined by a set number of sub-carriers over multiple OFDM symbols. While the number of sub-carriers remains fixed for the BACH, the sub-carriers for any given BACH will hop from one symbol to another. Thus, the BACH is defined by a hopping pattern for a select number of sub-carriers over a sequence of symbols.

Abstract translation: 本发明提供了一种用于在OFDM环境中支持可变比特率服务的技术，同时最小化衰落信道的变化和干扰的影响。 通常，基本接入信道（BACH）由多个OFDM符号上的设定数量的子载波定义。 虽然子载波的数量对于BACH保持固定，但是对于任何给定的BACH的子载波将从一个符号跳到另一个符号。 因此，BACH由符号序列上的选择数量的子载波的跳频模式定义。

Abstract: Time cycles in the physical layer of a passive optical network may be shared by multiple transmitting network devices (ONUs) to enable transmission of time sensitive traffic in a time sensitive manner. By allocating channels within the cyclic frame structure of the physical layer of the network, transmission of data from the ONUs to the OLT may be smoothed to enhance time dependent characteristics of the network. Where the underlying physical layer is a SONET/SDH based network, each SONET/SDH frame is divided into a given number of channels, such as 125 channels each of which is 1 nullS long. Each ONU is allocated one or more channels on each frame in which to transmit data to the OLT. The total bandwidth allocated to a given ONU is determined based on the number of channels allocated to that ONU.

Abstract: High bandwidth services provided in the core of the network may be extended to the network edge by utilizing one or more underground wireless communications links. The underground communications link may be formed by burying a broadcasting antenna in a first underground location and then burying another underground antenna at a geographic point where services are desired. By transmitting the signals underground, it is possible to reach a large number of remote sites without undertaking the expense associated with providing direct high-speed fiber optic, cable, or wireline connections to those sites. Additionally, since the transmission is underground, the wireless communications may be provided in a portion of the spectrum otherwise licensed for use aboveground. This reuse of spectrum in a different transmission medium results in a large increase in the amount of data that may be transmitted over the existing allocated wireless spectrum.

Abstract: The present invention provides for mapping of plurality of IP flows to a plurality service instances. A plurality of IP flows are received at a PDSN. The header information associated with each IP flow at the PDSN is parsed. Each IP flow is mapped to its corresponding service instance. The mapping criteria are defined by a flow filter. The flow filter can be generated within the PDSN, or outside of the PDSN such as by an MS. Each IP flow is transmitted on its corresponding service instance to its endpoint, such as an MS.

Abstract: A low data rate wireless channel (control channel) is associated with a high speed broadcast mode wireless channel (data channel). The data channel is divided into discrete code or time slots (access slots), that are unassigned to any particular recipient or user until requested. In the event that a particular user requires a particular resource, access slots are requested through the control channel, allocated to the user, and allocation information is passed back to the requesting user through the control channel. By diverting setup and control traffic to a low-bandwidth, always-on quasi real-time control channel, capacity on the data channel can be freed up to enable the high-speed data channel to be dedicated to transmission of high-bandwidth traffic. Thus, scarce high-bandwidth resources can be utilized to the full extent to reduce the probability of time slots not being utilized due to scheduling conflicts and without requiring transmissions to stop to perform housekeeping functions between transmissions.

Abstract translation: 低数据速率无线信道（控制信道）与高速广播模式无线信道（数据信道）相关联。 数据信道被分成离散码或时隙（接入时隙），在被请求之前未分配给任何特定接收者或用户。 在特定用户需要特定资源的情况下，通过分配给用户的控制信道请求接入时隙，并且通过控制信道将分配信息传回给请求用户。 通过将设置和控制流量转移到低带宽，始终在线的准实时控制信道，可以释放数据信道上的容量，以使高速数据信道专用于传输高带宽流量。 因此，可以充分利用稀少的高带宽资源来减少由于调度冲突而不被利用的时隙的概率，并且不需要传输来停止在传输之间执行内务管理功能。

Abstract: A method of allocating bandwidth resources in a telecommunications network to which a plurality of devices are connected, involves the steps of: a) receiving from a first of the devices engaged in a call a suspend signal indicative that outgoing traffic from that device has been temporarily suspended, while the device remains engaged in the call; and b) upon receipt of the signal, allocating additional bandwidth to one or more other of the devices. The allocation of bandwidth can be carried out by one of the devices engaged in a call, or by a network bandwidth allocation device which oversees the bandwidth allocation used by each calling device and adjusts allocations dynamically as devices suspend and recommence their outgoing traffic. The adjustment of bandwidth allocation is preferably achieved by the device(s) switching codecs, and the suspend signals preferably result from the deactivation of transmissions in response to a voice activity detection unit in the first device.

Abstract: An optical core node that includes optical switching planes interfaces, at input, with multi-channel input links and, at output, with multi-channel output links. The number of channels per link can differ significantly among the links, necessitating that the input (output) links have different connection patterns to the switching planes. Such an optical core node requires new methods of assigning an incoming wavelength channel to one of the optical switching planes. The assignment of the channels of input and output links to input and output ports is established in a manner that increases input-output connectivity and, hence, throughput. Additionally, the networks that may be formed with such optical core nodes require new routing methods. A preferred method of selecting a path through the core node favors switching planes connecting to a small number of links. In a time-division-multiplexing (TDM) mode, the method of path selection is complemented by temporal packing of TDM frames.

Abstract translation: 一种光核心节点，其包括光输入平面接口，在输入端具有多通道输入链路，并且在输出端具有多通道输出链路。 每个链路的信道数量可能在链路之间显着不同，因此输入（输出）链路必须具有与交换平面不同的连接模式。 这种光核心节点需要将入射波长信道分配给光交换平面之一的新方法。 将输入和输出链路的通道分配给输入和输出端口以增加输入输出连接性，从而增加吞吐量的方式建立。 此外，可能由这种光核心节点形成的网络需要新的路由方法。 选择通过核心节点的路径的优选方法有利于连接到少量链路的交换平面。 在时分复用（TDM）模式中，路由选择的方法由TDM帧的时间打包补充。
