METHOD AND APPARATUS FOR MANAGING CONNECTION IDENTIFICATION IN PAIRING

摘要

An embodiment of the present invention relates to a method for enabling a transmission terminal to execute a pairing process in device to device communications makes a feature of comprising: a step of classifying a plurality of link ID for dividing data transceiving channel into a part group of one or more link IDs; a step of selecting an available candidate link ID part group among the part groups of the link IDs; a step of selecting the available candidate link ID part group among the part group of the link ID; a step of transmitting the pairing request message including the candidate link ID part group information; and a step of receiving a pairing response message corresponding to the pairing request message. According to the embodiment, the method has a good point which does not have large overhead for searching the connection ID when the number of the terminals is small at the assignment of the connection ID in the device to device communication environment. Therefore, the overlapping probability of the connection ID between the terminals is reduced even if the number of the terminals is increased in a specific range. The method has an effect capable of providing the smooth communication between the device and the device.
