Abstract: A multimedia call is completed to a mobile user, who registered to receive a multimedia call at a multimedia terminal using a portable intelligent device. A mobile user record including a physical address of a multimedia terminal and a user address is stored. In response to a multimedia call addressed to the user address, the physical address is determined and call notification information is transmitted to the multimedia terminal at the physical address. The multimedia call is then completed to the multimedia terminal at the physical address.

Abstract: Interference is reduced with a multiple-input-multiple-output (MIMO) system having a set of basestations including a first basestation and a second basestation is reduced. Signals associated with the first basestation having its own antenna elements are received. The first basestation is associated with its own mobile stations each having their own antenna elements. Each signal associated with the first basestation is uniquely associated with a mobile station associated with the first basestation. Signals associated with the second basestation having its own antenna elements are received. The second basestation is associated with its own mobile stations each having their own antenna elements. Each signal associated with the second basestation is uniquely associated with a mobile station associated with the second basestation. Signals associated with the first basestation are jointly detected in conjunction with the signals associated with the second basestation to produce a set of detected signals.

Abstract: Systems and methods for automatically segmenting speech inventories. A set of Hidden Markov Models (HMMs) are initialized using bootstrap data. The HMMs are next re-estimated and aligned to produce phone labels. The phone boundaries of the phone labels are then corrected using spectral boundary correction. Optionally, this process of using the spectral-boundary-corrected phone labels as input instead of the bootstrap data is performed iteratively in order to further reduce mismatches between manual labels and phone labels assigned by the HMM approach.

Abstract: A staggered startup method and system for a cyclic prioritized multiple access (CPMA) system reduce interference between overlapping first and second wireless LAN cells contending for the same medium. Each cell includes a respective plurality of member stations. A first member station in the first cell coordinates a periodic sequence of first contention-free sessions. Each contention-free session includes multiple bursts with other member stations in the first cell. The first member station retains control of the medium by using interframe spaces sufficiently short between the bursts so that the multiple bursts appear to contending stations to be a single instance of activity in the medium during a session until an end of a session. A second member station in the second cell listens to the activity in the medium and detects an end to one of the first contention-free sessions indicated by an interval longer than a PIFS idle interval following an end to the activity in the medium. The second member station then sets a post-backoff delay to periodically transmit a minimal interval after the first contention-free sessions of the first member station. The second member station coordinates in the second cell a periodic sequence of second contention-free sessions. In this manner, contention-free sessions are interleaved on a periodic basis in the first and second cells.

Abstract translation: 用于循环优先多址（CPMA）系统的交错启动方法和系统降低了竞争相同介质的重叠的第一和第二无线LAN小区之间的干扰。 每个小区包括相应的多个成员站。 第一个小区中的第一个成员站协调第一个无竞争会话的周期性序列。 每个无争用会话包括与第一个小区中的其他成员站的多个突发。 第一成员站通过使用在突发之间足够短的帧间空间来保持对介质的控制，使得多个突发似乎将竞争站看作是在会话期间的介质中的单个活动实例，直到会话结束。 第二小区中的第二成员站监听介质中的活动，并且检测到在介质中的活动结束之后由比PIFS空闲间隔更长的间隔指示的第一无竞争会话之一的结束。 然后，第二成员站设置回退后延迟，以在第一成员站的第一无争用会话之后周期性地发送最小间隔。 第二成员站在第二小区中协调第二无竞争会话的周期性序列。 以这种方式，无竞争会话在第一和第二小区中被周期性地交织。

Abstract: A new type of data transport service which uses a frame relay layer 2 data link connection identifier (DLCI) to select among various service types, feature sets, and/or closed user groups (CUGs) . A layer 3 address may be extracted from a layer 2 frame, and the layer 3 address information may be used to route a data packet over a packet-switched network according to the service classes, feature sets, and/or CUGs selected. At the destination, the layer 3 data packet may again be enclosed in a layer 2 frame with a DLCI indicating the service classes, features sets, and/or CUGs. Because the use of conventional permanent virtual circuits (PVCs) is not required in aspects of the invention, new methods of measuring and managing network traffic are presented.

Abstract: A communication network apparatus and method for routing communication signals from a source device to a receiving device. The apparatus performs only local processing on communication signals to thereby increase the speed of processing the signals. A plurality of the processing nodes are combined into a plurality of sub-networks that comprise the network apparatus. Each processing node of a sub-network need only process address information pertaining to the node's current layer, one layer above it, if any, and one layer below it, if any. Additionally, each processing node has associated communication signal frequencies/wavelengths that identify the processing node as the intended recipient of the communication signal. When a communication signal having a carrier signal with a frequency/wavelength corresponding to the processing node is received, the processing node demodulates the carrier signal and forwards the communication signal data to a processing module used to process address information to determine how to route the communication signal through the network. Communication signals may be assigned nullexpressnull frequencies/wavelengths, in which case, all of the processing nodes, except the destination processing node, of the network pass the communication signal without performing processing on the communication signal.

Abstract translation: 一种用于将来自源设备的通信信号路由到接收设备的通信网络设备和方法。 该装置仅对通信信号执行本地处理，从而提高处理信号的速度。 多个处理节点被组合成包括网络装置的多个子网络。 子网络的每个处理节点仅需要处理与节点当前层有关的地址信息，如果有的话，则在其上方有一层，如果有的话，则需要一层。 另外，每个处理节点具有将通信信号频率/波长识别为通信信号的预期接收者的处理节点。 当接收到具有与处理节点对应的频率/波长的载波信号的通信信号时，处理节点解调载波信号，并将通信信号数据转发到用于处理地址信息的处理模块，以确定如何路由通信 通过网络发出信号。 通信信号可以被分配“快速”频率/波长，在这种情况下，网络的目的地处理节点除外的所有处理节点都通过通信信号，而不对通信信号进行处理。
