Network operation system and method

A network operation method in a network infrastructure including two or more heterogeneous networks, the network operation method comprising:

• extracting service capability (SC) associated to multiple network capabilities (NCs), units for each application service required;
• matching NCs required for SCs to the SCs;
• and
• generating a transaction unit in which the SCs and the NCs are matched;
• wherein the generating of the transaction unit comprises:
• matching the SCs and the NCs on a one-to-one basis;
• and
• generating transaction information for an NC transaction;
• and
• wherein the generating of the transaction unit further comprises generating a multi-transaction unit which includes links of two or more basic transaction units and in which multiple SCs and multiple NCs are matched.

A network capability (NC) trading control method for terminal-to-terminal group networking, the NC trading control method comprising:

• receiving a connection authorization request of a terminal to form a group;
• requesting matching of a service capability (SC) to be applied to an authorized terminal group and a network capability (NC) corresponding to the SC;
• generating a matching logic table in response to the request and delivering an NC combination and operating conditions to a networking management system;
• and
• switching a trading control link of the matching logic table to an active mode in response to a request for NC trading activation and sending an NC control request to the networking management system;
• wherein the requesting of the matching comprises:
• maintaining an SC combination rule to be provided as a profile;
• determining a charging rule for an owner of a corresponding terminal group;
• and
• requesting matching of an SC to be applied to the terminal group and an NC corresponding to the SC after the charging rule is determined.
