Network service system, computer storage medium for communication, and network service method

A network service system, operably communicating with a remote user terminal and a remote target terminal, the network service system comprising:

• a communication module and a data processor, wherein
• the data processor comprises a storage module, the storage module storing an identification code set by the network service system and at least one target code associated with the target terminal, the at least one target code representing at least one of a phone number of the target terminal, a social network account, and an application account related to the network service system;
• and
• the communication module is configured to receive a communication request from the user terminal, the communication request comprising the identification code;
• and the communication module is further configured to determine, according to the identification code, to establish a communication connection with the target terminal by using one of the at least one target code, so that the target terminal communicates with the user terminal in real-time by using an Internet Protocol (IP) network,
• wherein after establishing the real-time communication between the user terminal and the target terminal, the communication module disconnects respective communication connections between the network service system and the user terminal and the target terminal, so that the real-time communication between the user terminal and the target terminal is performed without using the network service system.
