Abstract: A location update method, and a heterogeneous network communications system and a device are provided herein. The method includes: an information server receives a location update request message from a multimode terminal; the information server searches the pre-stored location area mapping information for the location area information of the second interface; and the information server sends the location update request message of the second interface to a second Paging Coordinator (PC) corresponding to the second interface, where the request message carries the found location area information of the second interface so that the second PC can update existing location area information of the second interface. The system includes an information server, a first PC and a second PC.

Abstract: A method of operating a communication system is disclosed which includes, in a wireless communication device, transferring a wireless beacon signal and responsively receiving a wireless access request from a user device, determining if a user identifier received with the wireless access request has usage credits in a data structure, exchanging wireless signals with the user device and with a wireless communication network based on the usage credits to provide a wireless communication service to the user device, and decrementing the usage credits for the user identifier in the data structure. The method also includes wirelessly transferring usage credit updates for receipt in a master data structure.

Abstract: In one embodiment, a first system receives N data transmissions from a second system. The first system combines N ACK/NACK responses, corresponding to the N data transmissions received, and encodes the combined N ACK/NACK responses by selecting a position of a communication channel over which the first system sends ACK/NACK transmissions to the second system and setting a value for each bit sent during each ACK/NACK transmission based on the combined N ACK/NACK responses. The first system sends the bits at the selected position of the communication channel. The second system, upon receiving the bits sent at the selected position of the communication channel, decodes the N ACK/NACK responses based on the position at which the bits are sent and the bits.

Abstract: A system for receiving data includes a receiver configured to receive a radio frequency communication signal comprising at least one superframe, the at least one superframe having at least a first data stream and a second data stream encoded therein, wherein the receiver decodes at least one of the first data stream and the second data stream.

Abstract: The scheduling of a processing job to be performed by at least a portion of a cluster of processing resources distributed across multiple machines. The processing job is associated with a certain entity having a certain amount of guaranteed processing resources on the cluster. If there are enough processing resources to perform the job, then the job may be initiated. On the other hand, if there are not enough processing resources to perform the job, and there are yet some remaining processing resources that are guaranteed to the certain entity, then one or more other jobs that are associated with other entities are at least partially preempted until there are enough processing resources to perform the processing job.

Abstract: A radio unit and other units communicate with a base station apparatus. The radio unit and other units are capable of performing multiple types of communications. An acquisition unit acquires communication quality and moving speed. A determination unit determines the execution of a handover based on acquired quality and moving speed. The determination unit specifies, from among acquired quality and moving speed, a parameter used to determine the execution of a handover, based on the type of performed communication. An instruction unit instructs the radio unit and other units to perform a handover.

Abstract: A computing device retrieves a set of configuration files of devices associated with a network to be analyzed and extracts from the set of configuration files Internet protocol (IP) address information to form an IP address database. The computing device also extracts from the set of configuration files border gateway protocol (BGP) routing protocols to form a BGP routing database. The computing device analyzes the IP address database and the BGP routing database to generate a database of calculated network connection information for the devices associated with the network. The computing device conducts live network discovery, on the network and based on the IP address database, to generate a database of discovered connection information, and merges the database of calculated network connection information and the database of discovered connection information to form a master database from which output files may be generated.

Abstract: A frequency block allocation apparatus based on a single carrier frequency division multiple access method includes an allocation index computation target selector that selects frequency block groups, each consisting of one or more continuous non-allocated frequency blocks from a set of non-allocated frequency blocks; an allocation index computation unit that computes an allocation index for each target pair of each frequency block group and a terminal; and a frequency block allocation unit that determines one of the target pairs to be a frequency block allocation target, in accordance with priority based on the computed allocation indexes.

Abstract: Bandwidth is allocated by leveraging a bursty characteristic of data transmission signals to efficiently utilize network resources. Network performance is observed over a time period to identify patterns of data transmission rates as different signals are processed. To compensate for the fact that different jobs/tasks peak at different times, the total bandwidth limit may be increased by a scaling factor. The scaling factor is calculated using information obtained by observing network performance during the time period. The scaling factor is used to increase the total bandwidth available for all jobs/tasks executing during the time period without exceeding any bandwidth limits. The data transmission rate of each job/task may then be adjusted to utilize the newly available bandwidth.
