Abstract

A method and apparatus are provided for performing multiple service discovery in a wireless environment. The method includes generating a probe request containing a class information and a sub class information of a plurality of advertiser devices by a seeker device, transmitting the probe request for service discovery to at least one advertiser device of the plurality of advertiser devices and receiving a probe response from the at least one advertiser device. The probe response comprises at least one of the class information and the sub-class information associated with the at least one advertiser device.

First claim

1 - 10 . (canceled)

11 . A method for providing multiple service discovery in a wireless environment, the method comprising the steps of:
generating, by a seeker device, a probe request including class information and sub class information of a plurality of advertiser devices; transmitting the probe request for service discovery to at least one of the plurality of advertiser devices; and receiving a probe response from the at least one of the plurality of advertiser devices, wherein the probe response includes at least one of the class information and the sub-class information associated with the at least one of the plurality of advertiser devices.

12 . The method of claim 11 , further comprising:
identifying an advertiser device type of the at least one of the plurality of advertiser devices, based on the class information and the sub class information associated with the at least one of the plurality of advertiser devices; and displaying the identified advertiser device type on a display screen of the seeker device.

13 . The method of claim 11 , wherein generating the probe request comprises of:
defining a set of service names corresponding to a plurality of services available at the plurality of advertiser devices; generating a hash set for each of the defined set of service names, wherein the hash set includes at least one of the defined service name, a class code, and a sub class code corresponding to the plurality of advertiser devices; and appending the generated hash set in the probe request.

14 . The method of claim 13 , wherein generating the hash set for each of the defined set of service names comprises:
generating a bit map of a predefined hash set for each class and sub class of the plurality of advertiser devices; inputting the generated bit map of the predefined hash sets to a bloom filter; performing a logic function between each of the generated bit maps corresponding to the plurality of advertiser devices; and receiving, from the bloom filter, a resultant bit map that is an aggregated hash value corresponding to a second hash value.

15 . The method of claim 14 , wherein the second hash value corresponds to a sequence of hash values of a service name and a class and sub class associated with each of the plurality of advertiser devices.

16 . The method of claim 13 , wherein generating the hash set for each of the defined set of service names comprises creating a list of a specific sequence of hash sets for the defined service names and class and sub class codes of the plurality of advertiser devices.

17 . The method of claim 13 , wherein generating the hash set for each of the defined set of service names comprises creating a hash set including a reverse domain name system (DNS) service name with a device role, a class code and a sub class code as a string of information.

18 . The method of claim 11 , wherein the probe response comprises:
a service name with an advertiser device role; a class information string including a class code and a sub class code, and an advertise service attribute element providing information for the service offered by the at least one of the plurality of advertiser devices.

19 . A system for providing multiple service discovery in a wireless environment, the system comprising:
a seeker device in communication with a plurality of advertiser devices, wherein the seeker device is configured to:
generate a probe request including class information and sub class information of at least one of the plurality of advertiser devices;
transmit the probe request for service discovery to the at least one of the plurality of advertiser devices; and
receive a probe response from the at least one of the plurality of advertiser devices, where the probe response includes at least one of the class information and the sub-class information associated with the at least one of the plurality of advertiser devices.

20 . The system of claim 19 , wherein the seeker device is further configured to:
identify an advertiser device type of the at least one of the plurality of advertiser devices, based on the class information and the sub class information associated with the at least one advertiser device; and display the identified advertiser device type on a display screen of the seeker device.

21 . An apparatus for performing multiple service discovery in a wireless environment, the apparatus comprising:
a controller; and a service discovery module, which under the control of the controller, is configured to:
generate a probe request including class information and sub class information of at least one of a plurality of advertiser devices;
transmit the probe request for service discovery to the at least one of the plurality of advertiser devices; and
receive a probe response from the at least one of the plurality of advertiser devices, where the probe response includes at least one of the class information and the sub-class information associated with the at least one of the plurality of advertiser devices.

22 . The apparatus of claim 21 , wherein the service discovery module is further configured to:
identify an advertiser device type of the at least one of the plurality of advertiser devices, based on the class information and the sub class information associated with the at least one advertiser device.

23 . The apparatus of claim 22 , further comprising a display configured to display the identified advertiser device type of the seeker device.
