An implementing method for terminal communication, which is used for realizing communication between terminals based on a terminal real name system, wherein the method comprises: a first visitor location register judging, according to an identifier of a first terminal which initiates a communication, whether the first terminal has registered first real name system information in a network, wherein the first visitor location register is a location register which is currently visited by the first terminal, the communication is initiated by the first terminal to a second terminal, the first real name system information comprises the identifier of the first terminal and subscriber identity information of the first terminal, and the subscriber identity information corresponds to the identifier of the first terminal; in a case when the first visitor location register determines that the first terminal has not registered the first real name system information in the network, terminating the communication initiated by the first terminal; the method further characterized in that: in a case when the first visitor location register determines that the first terminal has registered the first real name system information, the method further comprises: a second home location register to which the second terminal belongs judging, according to an identifier of the second terminal, whether the second terminal has registered second real name system information in the network, and allowing, when a judging result is "yes", the second terminal to accept the communication initiated by the first terminal, otherwise, prohibiting the second terminal from accepting the communication initiated by the first terminal, wherein the second real name system information comprises the identifier of the second terminal and subscriber identity information of the second terminal. a first visitor location register judging, according to an identifier of a first terminal which initiates a communication, whether the first terminal has registered first real name system information in a network, wherein the first visitor location register is a location register which is currently visited by the first terminal, the communication is initiated by the first terminal to a second terminal, the first real name system information comprises the identifier of the first terminal and subscriber identity information of the first terminal, and the subscriber identity information corresponds to the identifier of the first terminal; in a case when the first visitor location register determines that the first terminal has not registered the first real name system information in the network, terminating the communication initiated by the first terminal; the method further characterized in that: in a case when the first visitor location register determines that the first terminal has registered the first real name system information, the method further comprises: a second home location register to which the second terminal belongs judging, according to an identifier of the second terminal, whether the second terminal has registered second real name system information in the network, and allowing, when a judging result is "yes", the second terminal to accept the communication initiated by the first terminal, otherwise, prohibiting the second terminal from accepting the communication initiated by the first terminal, wherein the second real name system information comprises the identifier of the second terminal and subscriber identity information of the second terminal. in a case when the first visitor location register determines that the first terminal has registered the first real name system information, the method further comprises: a second home location register to which the second terminal belongs judging, according to an identifier of the second terminal, whether the second terminal has registered second real name system information in the network, and allowing, when a judging result is "yes", the second terminal to accept the communication initiated by the first terminal, otherwise, prohibiting the second terminal from accepting the communication initiated by the first terminal, wherein the second real name system information comprises the identifier of the second terminal and subscriber identity information of the second terminal. a second home location register to which the second terminal belongs judging, according to an identifier of the second terminal, whether the second terminal has registered second real name system information in the network, and allowing, when a judging result is "yes", the second terminal to accept the communication initiated by the first terminal, otherwise, prohibiting the second terminal from accepting the communication initiated by the first terminal, wherein the second real name system information comprises the identifier of the second terminal and subscriber identity information of the second terminal.
