Description

  The present invention relates to a presence information utilization system, for example, a presence information utilization system for a dual mobile phone having two functions of an IP phone function in a specific area using a wireless LAN and a mobile phone function using a mobile phone network. It can be applied.

  Conventionally, presence information of an IP phone used in a facility is managed (locally managed) in a presence server owned in the facility, so a call is made to an IP phone in the facility from the outside. When making a call, the communication carrier (communication telephone company) side could not perform call control on the caller side using the presence information of the called party managed in the facility.

Recently, there has been a technology for accessing the facility via the Internet and referring to presence information managed in the facility using a reference tool such as the Web (see Patent Documents 1 and 2). There is no method for performing call control on the telephone network side with reference to presence information in the facility to which the owner of the telephone as the call destination belongs when a call is made from the terminal.

  S601: The control unit 301 of the exchange equipment 300 transfers the received call to the carrier center equipment 500 side unconditionally.

  S602: The call transferred (routed) to the carrier center facility 500 is converted into the SIP protocol by the 3G-SIP gateway 502 and connected to the SIP-AP server 504 via the SIP server 501. Upon receiving the incoming call, the SIP-AP server 504 activates an application “presence confirmation AP” for confirming the presence information of the terminal of the incoming call.

S603: The “presence confirmation AP” activated on the SIP-AP server 504 inquires the dual mobile phone table (see FIG. 2) of the terminal information DB 507 based on the mobile phone number of the destination terminal and receives the incoming call. It confirms whether the previous terminal is a dual mobile phone, and acquires service expiration information. Processing branches as TRUE if the destination terminal is a dual mobile phone and the current date is within the expiration date, and FALSE otherwise. Note that the branch destination at the time of FALSE is step S309, which is different from the first embodiment.

  According to the presence information utilization system of the second embodiment, the same effects as those of the first embodiment can be obtained, and further, the following effects can be obtained.

  In the case of the first embodiment, since it is necessary for the communication carrier to determine whether or not it is a dual mobile phone on the exchange equipment 300 side, which is an in-network equipment, a network for a plurality of exchange equipment installed at each site. Refurbishment is required, and the investment for realization will increase. On the other hand, in the case of the second embodiment, all the determinations as to whether or not the mobile phone is a dual mobile phone are performed on the carrier center facility 500 side. Compared to the embodiment, the same processing as that of the first embodiment can be realized with a small investment.

(C) Other Embodiments In each of the above embodiments, a fixed network, a mobile phone network, and an IP network are given as examples, and a gateway is used to connect different communication networks. If IP implementation is realized, the processing described in each of the above embodiments can be realized without using a gateway.
