  • Publication number: 20070066326
    Abstract: Methods, systems, and computer program products for facilitating delivery of messaging service messages between domains of different type are disclosed. According to one method, a messaging service message including a messaging service address parameter storing a first address value is received. It is determined whether the messaging service message is being sent from a domain of the first domain type to a second domain of the second domain type, where the first domain type is different from the second domain type. It is also determined whether the message is of a type used to communicate an MS delivery address at which a mobile station can receive MS messages.

  • Patent number: 5042001
    Abstract: A method for approximating mathematical functions using polynomial expansions is implemented in a numeric processing system (10) which comprises a control and timing circuit (18), a microprogram store (20) and a multiplier circuit (34). The multiplier circuit (34) may comprise a rectangular aspect ratio multiplier circuit (40) having an additional ADDER INPUT to enable the repeated evaluation of first order polynomials to evaluate polynomial expansions associated with each mathematical function. A constant store (28) is used to store predetermined coefficients for the polynomial expansion associated with each mathematical functions. The microprogram store (20) is used to store argument transformation routines, polynomial expansions and result transformation routines associated with each mathematical function.
