International Classification:

US Classification:

711141, 711147, 711154, 707201, 707203, 707200

Abstract:

A system and method for efficiently performing memory intensive computations including a bidirectional synchronization mechanism for maintaining consistency of data on which computations will be performed. This can be used to solve various problems such as those in a business context. Synchronization occurs in a near-real-time fashion between data in a database and data stored in memory. The synchronization is accomplished by periodically scanning the database to see if any data has changed. If any data has changed, the changes are copied over to memory so that the data in memory is current. This update is accomplished without copying the entire database into memory each time data in the database changes.

Jin Yang - Castro Valley CA, US

Assignee:

Oracle International Corporation - Redwood City CA

International Classification:

G06F 9/44

US Classification:

717108

Abstract:

A high level language for Mathematical Programming modeling is provided within a low level general purpose object oriented programming language. Libraries can be provided with a standard low level language enabling the use of the high level programming semantics in the low level programming environment. Using the libraries, the user can easily build complex Mathematical Programming models by using high level constructs while still taking advantage of the runtime efficiency and general purpose computing offered by the low level language. In an embodiment, operator overloading of a low level language is used to build semantics of a high level language.

International Classification:

H04B 7/216
H04L 12/56

US Classification:

370331, 370401, 370466

Abstract:

A communications system for providing a user's mobile station (MS) with an Internet Protocol (IP) connectivity, has an IP network gateway for allocating an IP address to the MS to enable it to access an IP network. First and second base stations are respectively configured to support communications of the MS over first and second radio access networks using different radio access technologies. A first access gateway provides an interface between the IP network gateway and the first radio access network, whereas a second access gateway provides an interface between the IP network gateway and the second radio access network. A handover interface is provided between the first access gateway and the second access gateway for enabling the MS to switch between the first and second radio access networks with minimum latency.

Assignee:

Cellco Partnership - Basking Ridge NJ

International Classification:

H04W 36/00

US Classification:

455436, 455440, 370331

Abstract:

A communications system provides a robust and fast inter-base station handoff mechanism, e. g. for networks using Enhanced Base Stations (EBS) equipment. A method for connecting a mobile device to a destination base station in the wireless communications system, may include steps of receiving a mobile device measurement report, transferring context information from a serving base station to possible target base stations, and receiving admission control information from possible target base stations. A priority list of the possible target base stations is calculated and sent to the mobile device. The mobile device connects to one or more of possible target base stations according to the priority list. The method may also entail receiving a release message from one of the possible target base stations to which the mobile device has successfully established a wireless connection, to allow release of resources of the prior serving base station.

Abstract:

A method for measuring a call capacity of a cellular network which includes a plurality of sectors including a test sector and neighboring sectors defined by a number of base stations. A plurality of voice communication generators and a plurality of best effort generators are located both in the test sector and the neighboring sectors. Interference level from activated test units located within the neighboring sectors and the test sector represents total radio resources of the test sector. Throughput of best effort generators is measured while activating a predetermined number of voice communication generators within the test sector. An approximate relationship between the throughput of best effort generators and the number of activated voice communication generators is obtained. The call capacity within the test sector is determined from the approximate relationship between the throughput of best effort generators and the number of the activated voice communication generators. The call capacity within the test sector is adjusted to a real commercial communication environment based on real interference levels from the neighboring sectors.
