Method of updating into service category table in device and device for the same

摘要

A method for acquiring a service category table required for finding a service includes acquiring information on a latest service category table by identifying version information of a service category table from a broadcasting signal received from adjacent devices during a process of searching for a device supporting a service desired among devices, and acquiring a service category table of a latest version by establishing a session connection with a device supporting the service category table of the latest version based on the information. By acquiring the information on the latest service category table, a session connection with only the device providing the desired service is established so that an optimized session connection establishing process can be performed and a total network capacity can be efficiently managed. Also, the latest service category table can be acquired from the session-connected device, and thus a new service can be easily identified.

1. A method of updating into a latest service category table in a device, the method comprising:
receiving a broadcasting signal, by the device, the broadcasting signal comprising version information of a service category table for detecting a supportable target service based on Device to Device (D2D) direct communication from one or more adjacent devices located adjacent to the device; identifying in a subset of the one or more adjacent devices having a newer version of a service category table than a version of a service category table of the device, a counterpart device having the newer version of the service category table configured for use by another device; establishing a session connection with the counterpart device; and performing the target service with the counterpart device.
