A method and radio network controller (RNC) in a radio access network (RAN) for controlling access to a cellular telecommunication system. Upon receiving an access request from a given user equipment (UE) through a given radio base station (RBS), the RNC retrieves authorization information from an access control database within the RAN. The authorization information indicates whether the given UE is authorized to access the system through the given RBS. The RNC alternatively grants access or denies access to the UE based on the retrieved authorization information. The RBS is particularly useful for controlling access through small cells with limited capacity.

One embodiment of the present invention provides apparatus and methods for queuing access by large numbers of Internet or other network-based users to networked systems and resources with limited capacity. In one example embodiment, a queuing system provides user access to network resources, such as that of a ticketing system. A ticket queue queues a request received from a client system. A request processing module causes the client system to repeatedly transmit messages to the system during a first period, and in response to determining that the client system has ceased transmitting messages during the first period, the request is remove from the queue and/or cause the request goes unfulfilled.

The method comprises defining a Quality Reduction Factor (700), being a positive integer value, identifying at least one of the L layers corresponding to the Quality Reduction Factor, and discarding (702) said at least one of the L layers in progressive order in accordance with the Quality Reduction Factor, thereby recovering said memory capacity.

The complexity of user designs, the limited capacity of FPGA chips, and the limited number of chip pinouts have resulted in the development of inter-chip communication technology that necessitates the transfer of a large amount of data across a limited number of pins in the shortest amount of time. The inter-chip communication system transfers signals across FPGA chip boundaries only when these signals change values. Thus, no cycles are wasted and every event signal has a fair chance of achieving communication across chip boundaries. The inter-chip communication system includes a series of event detectors that detect changes in signal values and packet schedulers which can then schedule the transfer of these changed signal values to another designated chip. Working with a plurality of signal groups that represents signals at the separated connections, the event detector detects events (or changes in signal values). When an event has been detected, the event detector alerts the packet scheduler. The packet scheduler employs a token ring scheme as follows. When the packet scheduler receives a token and detects an event, the packet scheduler “grabs” the token and schedules the transmission of this packet in the next packet cycle. If, however, the packet scheduler receives the token but does not detect an event, it will pass the token to the next packet scheduler. At the end of each packet cycle, the packet scheduler that grabbed the token will pass the token to the next logic associated with another packet.

The system also comprises at least one allocation agent for dynamically allocating the resource user to at least one of the resources based at least in part on the resource user's power consumption profile.

Disclosed are email server management methods and systems that protect the ability of the infrastructure of the email server to process legitimate emails in the presence of large spam volumes. During a period of server overload, priority classes of emails are identified, and emails are processed according to priority. In a typical embodiment, the server sends emails sequentially in a queue, and the queue has a limited capacity. When the server nears or reaches that capacity, the emails in the queue are analyzed to identify priority emails, and the priority emails are moved to the head of the queue.

In a frequency analysis system, such as a signal detection system or a spectrum analyzer, the frequency domain resolution is enhanced by compression and decompression of the signal samples. The limited capacity of the data storage and/or data transfer resources limit the number of samples that can be stored or transferred. A compressor forms a compressed signal prior to data transfer or storage. A decompressor decompresses the compressed signal prior to transformation to the frequency domain, by a fast Fourier transform or other frequency domain transform. The frequency domain resolution is enhanced because more decompressed samples are available for the frequency domain transform. The compressor and decompressor apply computationally efficient algorithms that can be implemented to operate in real time.

The invention relates to a grouping method in frequency domain distributed video coding, which is improved aiming at a frequency domain Wyner-Ziv video coding scheme provided by a foreign research scholar, Stanford University Professor Bernd Girod, according to the characteristics of a wireless sensor network terminal device, such as low coding complexity, limited storage capacity and capability of transmitting in a network with poor channel quality and the like, and the Wyner-Ziv video coding characteristic. In the method, image frames are divided into three coding modes at a coding end, namely a skip mode, a low frequency mode and a full frequency mode; and combined decoding is performed by respectively selecting a side information estimation method for average interpolation, adaptive search motion estimation interpolation and adaptive search fine motion estimation interpolation according to a corresponding coding mode at a decoding end. The method can realize low bitrate transmission by eliminating a large number of interframe predictions and entropy coding, and also can acquire more accurate side information with low decoding price so as to effectively avoid the reduction of image decoding quality.
