Abstract: Systems and methods for identifying entities sharing a temporal pattern using bipartite graphs are described. In one embodiment, a method includes identifying a temporal pattern in a sequence of bipartite graphs for a sequence of records involving two entity types, where records of the sequence of bipartite graphs vary according to time. An embodiment may color code the edges between entity types in the sequence of bipartite graphs according to the at least one temporal pattern identified (e.g., increasing sales between a business representative and a customer). An embodiment may therefore identify a time-based relationship between at least two entities according to the coded edges. Given the identification of entities having a time-based relationships, groups of these entities may be identified and trends may be derived therefrom (e.g., increasing sales for business units of a particular geographic region).

Abstract: In an Error Correction Code (ECC)-based memory, a Single Error Correction Double Error Detection (SECDED) scheme is used with data aggregation to correct more than one error in a memory word received in a memory burst. By completely utilizing the Hamming distance of the SECDED (128,120) code, 8 ECC bits can potentially correct one error in 120 data bits. Each memory burst is effectively “expanded” from its actual 64 data bits to 120 data bits by “sharing” additional 56 data bits from all of the other related bursts. When a cache line of 512 bits is read, the SECDED (128,120) code is used in conjunction with all the received 64 ECC bits to correct more than one error in the actual 64 bits of data in a memory word. The data mapping of the present disclosure translates to a higher rate of error correction than the existing (72,64) SECDED code.

Abstract: Time division multiplexed input signals (i.e., separated into time slots) are spread in each time slot with a destination code. This spreading is applied for destination identification as opposed to signal information modulation. Each spreading signal is associated with a particular destination for a particular time slot. These spread signals are then combined on a code division bus. Output signals for retransmission to the destinations are recovered from the bus by application of despreading codes. Each despread signal has a destination code which appears in its individual time slot. In a variant code division multiplexed signals are directed to a destination by use of time slot interchanger to achieve time division switching to route the CDMA multiplexed channels.

Abstract: A control station communicates with at least one base station in a wireless network system. The control station includes a storage and a controller. The storage stores reference data for calculating the idle time according to the number of terminals. When an arbitrary one of the base stations undergoes a change in the number of terminals, the controller sets an idle time calculated by the reference data stored in the storage as the idle time of the base station using the changed number of terminals. As a result, the control station resets the idle time of each base station according to the number of terminals communicating with the base station, so that the base station can be relieved of a load of wireless resources, and smoothly accommodate terminals more than before.

With the relocation of the mobile station from the first base station to a second base station having a second higher-level network unit, the transmission-specific information stored in the first higher-level network unit is transmitted to the second higher-level network unit to continue the transmission after the relocation essentially directly from its latest state.

Abstract: A wireless digital communication system includes a base station in communication with a plurality of user equipment mobile terminals (UEs). The system prioritizes the forwarding of blocks of downlink data to designated ones of the UEs. The system employs adaptive modulation and coding (AM&C) to achieve improved radio resource utilization and provides optimum data rates for user services. Blocks of downlink (DL) data are received by the base station which requests downlink (DL) channel quality measurements only from those mobile terminals (UEs) with pending downlink transmissions. The UEs respond to the request by measuring and reporting DL channel quality to the base station, which then allocates resources such that the UEs will make best use of radio resources. The base station notifies the UEs of the physical channel allocation indicating the modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs.

Abstract: A circulating switch comprises switch modules of moderate capacities interconnected by a passive rotator. Data is sent from a one switch module to another switch module either directly, traversing the rotator once, or indirectly through at least one intermediate switch module where the rotator is traversed twice. A higher capacity extended circulating switch is constructed from higher-capacity switch modules, implemented as common memory switches and having multiple ports, interconnected through a multiplicity of rotators preferably arranged in complementary groups of rotators of opposite rotation directions. A polyphase circulating switch having a low switching delay is derived from a multi-rotator circulating switch by providing programmable rotators having adjustable relative rotator-cycle phases. A low delay high-capacity switch may also be constructed from prior-art medium-capacity rotator space switches with mutually phase-shifted rotation cycles.

Abstract: A client (10) transmits a service request signal to a Web server (20). The Web server which has received the service request signal generates an ID for each session, and transmits the ID to the client together with window information.

The voice processing server which has received the voice information and the ID processes the voice information, and transmits the processing result to the Web server together with the ID. The Web server prepares information reflecting the voice processing result obtained by the voice processing server in correspondence with the ID from the voice processing server, and transmits the information to the client.

Abstract: A transit memory assembly of a rotator-based switching node is logically partitioned into two sections, one operated as a common-memory switch fabric and the other as a time-shared space-switch fabric. The composition of data received at input ports of the switching node determines adaptive capacity division between the two sections.

The switching node includes rotators and a bank of transit-memory devices that facilitate the incorporation of any mixture of periodic, aperiodic, contention-free exclusive-access, concurrent-access, and multicast switching.

Abstract: Provided is a system and method for a multicast routing algorithm to work in infrastructure based mesh networks. It chooses access points, fixed infrastructure gateway nodes connected to each other and/or the global internet via a wired/wireless backbone, as a group of local multicast group leaders to form a multicast group leader cloud. Each local multicast group leader is elected on-demand according to the local multicast group member's request. Each local multicast group leader forms a local multicast tree rooted at this leader connecting all multicast group members associated with the AP. The processes of electing and maintaining local multicast trees rooted at APs enable efficient coordination with underlying unicast routing to exploit the advantages of fixed infrastructure nodes. Therefore, routing overhead and multicast tree convergence time are reduced. The method can support large networks with fast topology change due to fast convergence and reduced routing overhead.

Abstract: A high capacity switching node comprises a lattice structure of low-latency switch units and a plurality of balanced connectors interfacing electronic edge nodes to diagonal subsets of said switch units. The edge nodes may be collocated with the switch units or remotely located. The switch units may be bufferless, having optical switch-fabrics for example, thus requiring a compound vacancy-matching process. Using switch units each of dimension 64×64, a fast switching node having a dimension of the order of 10,000×10,000 can be constructed. With a typical wavelength-channel capacity of 10 Gb/s, the fast-switching node would scale to a capacity of 100 terabits per second, which is orders of magnitude higher than the capacity of known fast optical switches. A fast-switching optical switch of such scalability significantly reduces network complexity and cost.
