1. An information update system comprising:
- a plurality of application server apparatuses to serve a subscriber with respective application services through a corresponding SIP (session initiation protocol) server; and
a home subscriber server apparatus to store information regarding the subscriber and connected to the application server apparatus and to the SIP server, whereineach of the plurality of application server apparatuses comprises a transmitting unit to transmit an update request signal to the home subscriber server apparatus for requesting updating of the information regarding the subscriber, the update request signal including update contents, andthe home subscriber server apparatus comprises;
a selector configured to select, when receiving the update request signal, an updating method corresponding to said update request signal from a plurality of updating methods; and
an updating unit to update the information regarding the subscriber in accordance with the update contents contained in the update request signal through the selected updating method, whereineach of the plurality of application server apparatuses adds an identifier for identifying an updating method to the update request signal to be transmitted to the home subscriber server apparatus, andthe selector selects the updating method identified by the identifier added to the update request signal out of the plurality of updating methods, and further whereinthe updating method is one of a first win scheme and a last win scheme, the information is updated based on an update request signal received first by the home subscriber server when the first win scheme is selected by the selector, and the information is updated based on an update request signal received last by the home subscriber server when the last win scheme is selected by the selector,wherein the plurality of updating methods include;
a first updating method in which information is updated based on an update request signal received by the home subscriber server apparatus, if the update request signal has a same sequence number as a current sequence number which is currently stored in the home subscriber server apparatus and changed every time the home subscriber server apparatus updates information; and
a second updating method in which information is updated based on every update request signal which is received by the home subscriber server apparatus.

Abstract
A system includes a first server apparatus storing information and a plurality of second server apparatuses being connected to the first server apparatus. Each of the plurality of second server apparatuses transmits an update request signal for request to update the information stored in the first server apparatus to the first server apparatus. The first server apparatus selects, when receiving the update request signal, an update scheme corresponding to the update request signal out of a plurality of update schemes. The first server apparatus updates information corresponding to the update request signal with the selected update scheme.
