Abstract:
A mobile telecommunications system is described in which a base station allocates each mobile telephone a plurality of physical resource blocks by signalling data identifying a virtual resource block. The virtual resource block is mapped onto the plurality of physical resource blocks using stored mapping data. The mapping data is such that the mapped physical resource blocks are spaced over the operating bandwidth and all belong to the same resource block group subset.
Abstract:
There is described a method and apparatus for managing security for a connection between a user device and a communications network comprising at least one base station and a core network. In one embodiment, the method includes receiving at the core network security capability information for the user device connecting to the communications network. Security capability information for the base station is then obtained from memory or from the base station itself. The security capability information for the user device and the security capability information for the base station is then processed in the core network to select a security policy for a connection between the user device and the base station and the selected security policy is transmitted to the base station.
Abstract:
A system, method and computer program product creates an index based on accounting based data, as well as a portfolio of financial objects based on the index where the portfolio is weighted according to accounting based data. A passive investment system may be based on indices created from various metrics. The indexes may be built with metrics other than market capitalization weighting, price weighting or equal weighting. Non-financial metrics may also be used to build indexes to create passive investment systems. Additionally, a combination of financial non-market capitalization metrics may be used along with non-financial metrics to create passive investment systems. Once the index is built, it may be used as a basis to purchase securities for a portfolio. Specifically excluded are widely-used capitalization-weighted indexes and price-weighted indexes, in which the price of a security contributes in a substantial way to the calculation of the weight of that security in the index or the portfolio, and equal weighting weighted indexes. Valuation indifferent indexes avoid overexposure to overvalued securities and underexposure to undervalued securities, as compared with conventional capitalization-weighted and price-weighted.
Abstract:
A method and apparatus system for managing virtual mutual funds. A plurality of investment managers manage a plurality of accounts for a plurality of investors. The investors directly hold assets in the accounts so that the investors may take advantage of any tax benefits generated by transactions using the assets in the accounts. An investor may have one or more accounts and thus one or more managers. A manager may have one or more investors and thus one or more accounts to manage. A virtual mutual fund manager uses a holdings matrix and a lot matrix to track the asset lots in the accounts. When a manager wishes to make a trade affecting an investor, the virtual mutual fund manager determines which asset lots held by the investor should be used to execute the trade. Optionally, each investor may be associated with a tax-managed account. The tax-managed account is used by the virtual fund manager to make deferred “paper” trades thereby avoiding certain adverse tax consequences that may be created when an investor has multiple managers. Optionally, each investor may allow loss-harvesting trades to be executed on his or her behalf in circumstances where such trades may reduce the investor's tax obligations.
