  • Publication number: 20100178933
    Abstract: A terminal random access method for a cellular radio communications system and a method for generating a group identifier are provided. The terminal random access method for a cellular radio communications system includes steps of: transmitting random access preamble message by a terminal to a base station in a random access time slot in a radio frame; combining location information of the random access time slot in the radio frame and that in the frequency domain to generate a group identifier and sending a random access response message to the terminal after adding the group identifier and an individual identifier that corresponds to the random access preamble message to the random access response message by the base station; judging whether the random access response message that corresponds to the sent random access preamble message is received, by judging whether the group identifier and the individual identifier within the received random access response message are all expected values.

  • Patent number: 7630320
    Abstract: The present invention provides a method of scheduling packet in a wireless telecommunication system, in which the user packet queues to be transmitted are divided into the user packet queues with packet loss and the user packet queues without packet loss; for the user packet queues with packet loss, if a real time loss ratio of packet for the user exceeds a predetermined loss ratio threshold of packet, terminate a connection to the user; if the real time loss ratio of packet for the user does not exceed the predetermined loss ratio threshold of packet, schedule the user packet queues according to a volume of the loss ratio of packet; for the user packet queues without packet loss, schedule according to packet lengths, channel quality states, time delays and time delay jitters.

  • Publication number: 20090248737
    Abstract: A computing environment typically comprises a large set of diverse objects, such as files, user profiles, executable binaries, configuration information, and data caches, wherein such objects are typically stored and managed by an aggregation of systems, such as a file system, a system registry, and an assembly cache. An alternative representation of the computer system may comprise an object hierarchy configured to store all of the objects of the computing environment according to a simple organizational grammar. Various services (e.g., a synchronization service, a backup service, and a sharing service) may be provided to manage the diverse objects in a similar manner. The representation may also be provided to a variety of devices, which may render the computing environment in a consistent manner but adjusted to reflect the capabilities of the device and the user. The computing environment is thereby represented in a deployable, consistent, and extensible manner.

  • Publication number: 20090240728
    Abstract: A computing environment may be represented as a deployable object hierarchy, which may be organized according to an object hierarchy schema that is commonly shared among the computing environment host and the devices that are configured to render the computing environment. A particular object hierarchy schema is presented in detail for representing a computing environment, wherein many objects of the computing environment are modeled as resources that may be distinctly addressable (e.g., in a RESTful object hierarchy.) Many types of objects and properties thereof are presented in order to elucidate an exemplary object hierarchy schema and to illustrate exemplary objects and object hierarchies organized according thereto. Additional properties of various object hierarchy schemas include extensibility, deployability, and object addressing models with various advantages.

  • Publication number: 20090241104
    Abstract: The management of applications in a computing environment often involves a significant number of computing operations, such as acquiring the application, deploying data objects in various locations, and configuring the application with respect to the deployed device. Conventional computing environments may provide inadequate support throughout a typical application life cycle, especially for a computing environment distributed across many devices. Instead, the computing environment may be represented in a deployable object hierarchy that may be distributed to various devices. An application management service may therefore be provided to install representations of the application in the object hierarchy, and to support many other aspects of the application life cycle, such as application discovery, sharing, updating, and removal.

  • Publication number: 20090178124
    Abstract: Managing via a web portal a remote device from a source device connected to a communication network. A device ID is assigned to the remote device, and a remote management software for remote management of the remote device is not installed on the source device or the remote device. Based on the assigned device ID, a connection is established with the remote device via the communication network. A first instruction is received from a user for authenticating access to the web portal. The user is authenticated in response to the received first instruction. An online status is established for the authenticated user. A second instruction is received from the authenticated user requesting access to the remote device. The device ID of the remote device is validated. The validated device ID is associated with the authenticated user. A connection is established between the remote device and the web portal.

  • Patent number: 7035231
    Abstract: A method for controlling outer loop power in WCDMA system, which includes the following steps of: a) measuring a BER, and calculating an error between measured BER and a target BER and a change of the error; b) determining a degree of the error and a degree of the change of the error; c) calculating a degree of a SNR threshold adjusting step in accordance with the degree of the error and the degree of the change of the error; d) determining an actual SNR threshold adjusting step based on 40 the calculated degree of the SNR threshold adjusting step; and e) adjusting a SNR threshold in accordance with the actual SNR threshold adjusting step. The invention bypasses the determination and implementation of the corresponding function relations between the SNR threshold and the measured BER value by using a fuzzy control method, which is capable of implementing adaptive real-time trace, thereby improves control quality.

  • Patent number: 6540866
    Abstract: The present invention is directed to a method for the lamination of fluoropolymers to the surfaces of metals, and especially to copper, gold, and platinum, and to printed circuit board (PCB) substrate at temperatures substantially below the sintering temperatures or melting temperatures of the fluoropolymers. More specifically, the invention is directed to a method for surface modification of fluoropolymers by thermal graft copolymerization with concurrent lamination of metals in the presence of a functional monomer and an adhesive such as an epoxy resin. The process can be carried out under atmospheric conditions and in the complete absence of an added polymerization initiator. The laminated fluoropolymer-metal or fluoropolymer-PCB substrate interfaces exhibit T-peel strengths of no less than 8 N/cm. This invention can also be applied to substantially improve the adhesion between PCB substrates and metals.
