A presenting information providing apparatus and method for obtaining.

In general, the open presence service refers to a service in which a subscriber registers and updates his presence information, and provides a presence information of a registered subscriber when a presence information request is requested. Here, the presence information of the subscriber includes information on the activity, location, privacy, communication means, etc. of the subscriber. Such presence information can be classified into two types, static information and dynamic information. Static information refers to information that is provided as it is registered by the subscriber, and dynamic information refers to information provided by obtaining status information of the subscriber directly from the network based on the information registered by the subscriber. For example, information about communication means (eg, regular telephones) connected to a network that does not provide subscriber activity, location, privacy information or status information is static information. This static information is provided as the information registered in advance by the subscriber. As a result, the subscriber's activity, location, and privacy information suddenly changes, or a situation in which the user cannot receive a general telephone, but if the subscriber does not update the presence information, may be incorrect presence information.

In this general presence open service, information on communication means of a network that does not have a mechanism for providing the subscriber's activity, location, privacy, and presence information, that is, static presence information, is provided with the presence information provided without the subscriber's active renewal. There is no guarantee that it is up to date and correct.
