Then, the calling terminal 112 transmits the called terminal information and session description protocol (SDP) to the session establishing server 140. Invite message including the transmits (S315, S320, S325).

The session establishment server 140 transmits the packet service connection request message in the form of a short message to the destination terminal 114 through an SMS center (not shown) (S330). Here, the packet service connection request message is a message requesting the destination terminal 114 to execute a SIP registration and packet service application and to respond to an invitation message.

The called terminal 114 transmits the called party path activation request message to the communication network 130 to request the establishment of the called party packet session, and the communication network 130 sends the called party path activation response message to the called terminal 114. In step S335 and S340, the destination packet session is established.

The called terminal 114 transmits the called SIP registration message to the session establishment server 140 and executes a packet service application, and then responds to the invitation message received from the session establishment server 140 (200 OK). Respond by forwarding the message (S345, S350, S355, S360).

The session establishment server 140 receiving the response message from the called terminal 114 transmits it to the calling terminal 112, and the calling terminal 112 transmits the message through the Real-time Transport Protocol / RTP Control Protocol (RTP / RTCP). Packet service with the destination terminal 114 is performed (S365 and S370).

The communication network 130 integrates an account request message including intranet charging information, outgoing service region identification information, and incoming service region identification information, which is billing information on in-network resources used between the calling terminal 112 and the called terminal 114. It transmits to the billing server 150, and receives an account response message that is a response from the integrated billing server 150 (S375, S380).

The integrated billing server 150 receiving the account request message from the communication network 130 compares the outgoing service area identification information with the incoming service area identification information (S385). Here, the integrated billing server 150 indicates that the small base station ID included in the small base station ID database is included in the outgoing service area identification information and the incoming service area identification information before comparing the outgoing service area identification information with the incoming service area identification information. Check it.

The integrated billing server 150 processes the usage fee of the packet service for free or a discount depending on whether the originating service area identification information and the destination service area identification information match each other, and transmits the fee to one or more of the calling terminal 112 and the called terminal 114. Charge or the charge of the packet service is treated as a general charge and charged to one or more of the calling terminal 112 and the called terminal 114 (S390).

In other words, when the calling service area identification information and the called service area identification information match, the integrated billing server 150 processes the usage fee of the packet service performed between the calling terminal 112 and the called terminal 114 as free or discount. If a charge is imposed on at least one of the calling terminal 112 and the called terminal 114, and the calling service area identification information and the called service area identification information are inconsistent, the packet service performed between the calling terminal 112 and the called terminal 114 may be used. The charge is treated as a general charge and charged to one or more of the calling terminal 112 and the called terminal 114.

Here, the integrated billing server 150 may receive the calling terminal information and the called terminal information from the calling terminal 112 and the called terminal 114 or from the communication network 130.
