US 2013/0210359 A1 · METHOD OF UPDATING INTO SERVICE CATEGORY TABLE IN DEVICE AND DEVICE FOR THE SAME

Abstract

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.

Dependent claims

A method of updating into a latest service category table in a device, the method comprising:

receiving a broadcasting signal, by a first device, the broadcasting signal containing version information of a service category table for detecting a supportable target service based on Device to Device (D2D) direct communication from a second devices located adjacent to the first device;
analyzing the version information of the service category table contained in the broadcast ing signal and a provision intention of the service category table;
determining a counterpart device having a service category table of a higher version than that of the first device from the second devices having the provision intention of the service category table;
establishing a session connection with the determined counterpart device;
and
performing the target service with the counterpart device.

3 more elements

A machine-readable storage medium comprising a plurality of instructions, the plurality of instructions configured to, when executed by a processor, cause the processor to:

receive a broadcasting signal, the broadcasting signal containing version information of a service category table for detecting a supportable target service based on Device to Device (D2D) direct communication from a second devices located adjacent to the first device;
analyze the version information of the service category table contained in the broadcasting signal and a provision intention of the service category table;
determine a counterpart device having a service category table of a higher version than that of the first device from the second devices having the provision intention of the service category table;
establish a session connection with the determined counterpart device;
and
perform the target service with the counterpart device.
