Apparatus and method for providing service in wireless communication system
Disclosed is a sensor network, machine type communication (MTC), machine-to-machine (M2M) communication, and technology for Internet of Things (IoT), and is applicable to intelligent services such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. An access point (AP) includes a controller that generates a neighbor AP information message including location information of neighbor APs, and a transmitter that transmits the neighbor AP information message including a field indicating that a type of a currently transmitted message includes location information, a length field indicating a length of fields located after the length field in the currently transmitted message, and a location information field indicating location information of each of the neighbor APs.
1. An access point (AP) in a wireless communication system supporting a vehicle to infrastructure (V2I) scheme, the AP comprising:
a controller configured to generate a neighbor AP information message including location information of each of neighbor APs; and
a transmitter configured to transmit the neighbor AP information message,
wherein the neighbor AP information message includes a location information header field and location information fields indicating location information of the neighbor APs, and
wherein the location information header field includes information related to a number of the location information fields and a length of each of the location information fields.
2. The AP of claim 1 ,
wherein the neighbor AP information message further includes an operating class field indicating a channel band and a bandwidth of each of the neighbor APs and a channel number field indicating a last known primary channel of each of the neighbor APs.
3. The AP of claim 1 ,
wherein each of the location information fields includes a location sub-field including at least one of latitude information and longitude information of one of the neighbor APs.
4. The AP of claim 3 ,
wherein each of the location information fields further includes at least one of a basic service set identifier (BSSID) sub-field indicating a BSSID of one of the neighbor APs, and a short-service set identifier (short-SSID) field indicating a short-SSID of the AP.
5. The AP of claim 1 ,
wherein each of the location information fields includes a location/latitude sub-field indicating latitude information of one of the neighbor APs, and a location/longitude sub-field indicating longitude information of the AP.
6. The AP of claim 5 ,
wherein each of the location information fields further includes at least one of a basic service set identifier (BSSID) sub-field indicating a BSSID of one of the neighbor APs, and a short-service set identifier (short-SSID) field indicating a short-SSID of the AP.
7. The AP of claim 1 ,
wherein the information related to the number of the location information fields indicates a value obtained by subtracting a preset value from the number of the location information fields.
