A method for managing data traffic in a multi-user multiple-simultaneous-access (MUMSA) environment, for example in a code reuse multiple access (CRMA) environment or other physical environment having true random access with more than one transmission present at the same time, the method including estimating channel load for multiple users, then using the estimate of channel load to calculate a congestion threshold on an ongoing basis, at each terminal performing an experiment using that congestion threshold value and a random number generator to determine if a packet is eligible to be transmitted, transferring downstream virtual channel traffic and redistributing user terminals to affiliate with the proper downstream virtual channel.

The number of users and data capacity of wireless systems are increased by employing apparatus and method for increasing the number of spreading codes available in the system by providing a mechanism to reuse the already allocated spreading code or use the codes that may correlate to those already being used within the same sector/cell. This, in return, provides capacity improvement proportional to the number of added base station (BS) antennas for each cell. An antenna null steering technique for code allocation maintains the cross correlation properties of the codes only for the desired user and to obtain a gain in capacity improvement.

The present invention involves a new system and process for automatically controlling whether a displayed web page and associated frames displayed within a window of a web browser are secure or non-secure. For example, whether the displayed web page and associated frames are provided via a secure socket layer (SSL), i.e. a web page from an HTTPS address (secure), or simply via an HTTP address (non-secure), respectively. Specifically, the present invention uses a dynamic “Web Component” to remotely control web page security states. Further, the Web Component according to the present invention uses the same script and HTML for all implementations or instantiations of the Web Component, regardless of which, or how many, unique local clients make use of the Web Component. This code reuse is accomplished by using entry web pages, or “entry points,” as described in further detail below, to set the value of function properties or parameters of the Web Component for dynamically and controlling the security state of a web page having at least two frames. The script and/or HTML source code of the Web Component pages does not change based on each new implementation or instantiation. Consequently, little setup work is required for each implementation, and only a basic verification test pass is needed for each unique automatically customized Internet web page.

An apparatus and method for profiling candidate reuse regions and candidate load instructions aids in the selection of computation reuse regions and computation reuse instructions with good reuse qualities. Registers holding input values for candidate reuse regions are sampled periodically when the candidate reuse region is encountered. The register contents are combined into set-values. When a relatively small number of set-values account for a large percentage of occurrences, the candidate reuse region may be a good computation reuse region. Load instructions are profiled for the location accessed and the value loaded. The location and value are combined into location-values. The relative occurrence frequency of location-values can be used to evaluate load instructions as candidate instructions for reuse.
