An external device, to which the electronic device is connected over the Wi-Fi communication network, may be an Access Point (AP), and may include an AP for hotspots. 
     For convenience, a provider of a venue where an AP is installed, and an operator providing an AP-based Wi-Fi communication network will be referred to as a ‘service provider’. 
       FIG. 1  illustrates a system in which an electronic device receives service information provided from an information server of an external device or an AP according to various embodiments of the present disclosure. 
     Referring to  FIG. 1 , if an AP  200  is discovered or found over the Wi-Fi communication network, and determined as a hotspot AP, an electronic device  100  may request an information message for the AP  200  from an information server  300  connected to the AP  200 , via the AP  200 . 
     Upon receiving an information message from the information server  300  via the AP  200 , the electronic device  100  may perform an authentication process with an Authentication, Authorization and Accounting (AAA) server  400  using an authentication method specified in the information message, and automatically access (or connect with) the AP  200 . 
     If an option to display information about the connected AP  200  is selected, the electronic device  100  connected to the AP  200  may extract service information provided by a service provider from the information message, and display the extracted service information. A structure of the electronic device  100  will be described below with reference to  FIG. 5 . 
     The information server  300  may store operator information, venue information, uplink/downlink information, external network (e.g., 3 rd  Generation (3G) or Long Term Evolution (LTE)) information, access method information, authentication method information, and the like, of the AP  200 . 
     Therefore, upon receiving the request for an information message from the electronic device  100  via the AP  200 , the information server  300  may send an information message including the above information to the electronic device  100  via the AP  200 . 
     In various embodiments of the present disclosure, the service information provided by the service provider may be added in a Venue information format and an Operator information format in the information message. In addition, the service information provided by the operator of the AP may be added in a reserved field of the information message. 
       FIGS. 2A and 2B  illustrate a Venue information format, in which service information can be added, in an information message according to various embodiments of the present disclosure. 
     Referring to  FIGS. 2A and 2B , a Venue information format and a format of a Venue Name Duple field in the Venue information format are respectively illustrated. The Venue information format is specified in the Institute of Electrical and Electronics Engineers (IEEE) 802.11U standard, so its description will be omitted. 
     The venue information, which is actual data, may be stored in a Venue Name field of the Venue Name Duple field in  FIG. 2B . Therefore, the service information provided by the service provider may be added in the Venue Name field, together with the venue information or actual data. 
     In the Venue Name field may be stored “actual data+separator+service information”. If the service information is image metadata, “image://actual image data” may be stored, and if the service information is a web Uniform Resource Locator (URL) address, “http://web site url” may be stored. If the service information is a string, “string://additional string” may be stored, and if the service information is a download link, “download://address of file to be downloaded” may be stored. If the service information is a phone number, “phone://phone number” may be stored. 
     For example, if the venue information (or venue name) is “CoffeeA, COEX Center, Samsung-Dong, Seoul”, and the service information to be added is “http://www.coffeeA.com”, then “CoffeeA, COEX Center, Samsung-Dong, Seoul$$$http://www.coffeeA.com” may be stored in the Venue Name field. 
     “$$$” is a separator indicating the storage (or presence) of service information, and various other characters may be used as the separator. 
     In various embodiments of the present disclosure, the information server  300  may be an Access Network Query Protocol (ANQP) server. Therefore, the electronic device  100  may request an information message as an ANQP query from the information server  300 , and receive an information message from the information server  300  as a response to the query request. 
       FIGS. 3A and 3B  illustrate an Operator information format, in which service information can be added, in an information message according to various embodiments of the present disclosure.

The Operator Name element payload format is specified in the IEEE 802.11U standard, so its description will be omitted. 
     The service provider information, which is actual data, may be stored in an Operator Name field in the format of the Operator Name Duple field in  FIG. 3B . Therefore, in the Operator Name field may be added the service information provided by the service provider, together with the service provider information, which is actual data. 
     “Actual data+separator+service information” may be stored in the Operator Name field, like in the Venue Name field. Therefore, if the service information is image metadata, “image://actual image data” may be stored, and if the service information is a web URL address, “http://web site url” may be stored. If the service information is a string, “string://additional string” may be stored, and if the service information is a download link, “download://address of file to be downloaded” may be stored. If the service information is a phone number, “phone://phone number” may be stored. 
     By adding service information to venue information, which is actual data, in the Venue Name field in  FIGS. 2A and 2B , and adding service information provided by the service provider to the service provider information, which is actual data, in the Operator Name field in  FIGS. 3A and 3B , the service provider may provide the advertisements and other information that the service provider desires to additionally provide to users. 
       FIG. 4  illustrates an additional service information format, in which service information is stored, in a reserved field of an information message according to various embodiments of the present disclosure. 
     Referring to  FIG. 4 , in an “Info ID” field may be stored a specific value indicating additional service information for a venue name or additional service information for an operator name, and in a “Length” field may be stored a length value of a new format. Further, in a “Data type” field may be stored the type (e.g., image, web URL, string, download link, phone number, or the like) of the service information stored in a “Data” field, and in the “Data” field may be stored the actual service information. 
     If “Image” is stored in the “Data type” field, “image://actual image data” may be stored in the “Data” field, and if “Web URL” is stored in the “Data type” field, “http://web site url” may be stored in the “Data” field. If “String” is stored in the “Data type” field, “string://additional string” may be stored in the “Data” field, and if “Download link” is stored in the “Data type” field, “download://address of file to be downloaded” may be stored in the “Data” field. If “Phone number” is stored in the “Data type” field, “phone://phone number” may be stored in the “Data” field. 
     By providing an additional service information format, in which service information provided by the service provider is stored, to a reserved field of the information message as illustrated in  FIG. 4 , the service provider may provide the advertisements and other information that the service provider desires to additionally provide to users.
