Provided are a method and a system for providing a user tailored service using a social network service. The method includes at a user terminal, receiving a transaction approval message from a credit card company server when a customer uses a credit card, and obtaining purchase information of the customer based on the received transaction approval message, and forming a social network for sharing the purchase information of the customer with predetermined persons having a social relationship, wherein the predetermined persons include friends, family members, and colleagues of the customer.

Disclosed is a composite service control system resolving a conflict. A triggering condition of a new application that requests a registration is determined. When the determined triggering condition overlaps with a triggering condition of an existing registered application, determinations are made whether an intersection between an explicit conflict set of the new application and an explicit conflict set of the existing application exists and whether an intersection between an implicit conflict set of an API of the new application and an implicit conflict set of an API of the existing application exists; and The triggering condition and execution information of the existing application is reported. When either of the intersections exists, a defining of a conflict resolution policy or a changed application triggering condition for the new application is requested; otherwise the triggering condition and the execution information of the new application is stored in an information database.

A voice over packet (VoP) system using a plurality of digital signal processors (DSPs) and a speech processing method are provided. A plurality of first-stage DSPs perform encoding voice signal of calls allocated in advance, among calls from a circuit network, and output packets corresponding to the voice signal. A plurality of first memories are disposed corresponding to the plurality of first-stage DSPs, respectively, and store feature data obtained from calls input by the plurality of first-stage DSPs, respectively. A second memory stores feature data of the number of calls exceeding the processing capacity of first-stage DSPs among the calls input from the circuit network. A second-stage DSP performs encoding voice signal stored in the second memory and outputs packets corresponding to voice signal stored in the second memory. A packet network interface collects processing results of the first-stage DSPs and the second-stage DSP and distributes inputs from a packet network to first-stage DSPs. Based on identification information added to the feature data stored in the second memory, each of the first-stage DSPs moves the feature data to the first memory disposed corresponding to the first-stage DSP.
