Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to location based services and more particularly to geolocation for location based services. 
     2. Description of the Related Art 
     Geolocation is the identification of the real-world geographic location of an object, such as a radar, mobile phone or an Internet-connected computer terminal. In the context of mobile computing, geolocation refers to the determination of a geographic location of a computing device. The result of geolocation oftentimes is a set of geographical coordinates, but also can include a translated form of geographical coordinates such as the name of a location, an address of a location, or a location in reference to one or more landmarks. 
     Global positioning technology such as the global positioning system (GPS) in many instances can provide the raw coordinate data necessary to produce a resultant geographical location. However, other methodologies of geolocation can include radio frequency (RF) location such as time difference of arrival (TDOA), direction finding along a bearing, and computer protocol location in which a geographic location is associated with an Internet Protocol (IP) address, a media access control (MAC) address, an radio frequency identifier (RFID), hardware embedded article/production number, an embedded software number, an invoice, a Wi-Fi positioning system, or even user supplied location information. 
     Modern mobile devices may support one or more methodologies of geolocation—especially GPS. Yet, some mobile devices are resource constrained and do not include a GPS receiver limiting those devices to the more granular technique of computer protocol location. Even then, some mobile devices are so resource constrained as to not afford the requisite firmware to perform computer protocol location. Or, as is the case in many circumstances, computer protocol location may not be enabled by the end user, either knowingly, or more commonly unknowingly. In the latter circumstance, the advantage of geolocation and the use thereof in location based services cannot be realized. 
     BRIEF SUMMARY OF THE INVENTION 
     Embodiments of the present invention address deficiencies of the art in respect to geolocation services for mobile devices and provide a novel and non-obvious mobile wireless access point geolocation services proxy for mobile devices. In an embodiment of the invention, a method for mobile wireless access point geolocation services proxying for mobile devices is provided. The method includes providing in a wireless access point, a wireless hotspot for different mobile devices and establishing a cellular communications link between the wireless access point and the Internet. The method also includes routing messages between the mobile devices and the cellular communications link through the wireless hotspot. Finally, the method includes responding to a request from one of the mobile devices for geolocation data by obtaining location data for the wireless access point and transmitting the obtained location data to the one of the mobile devices over the wireless hotspot for use by the one of the mobile devices in acquiring location based services from a remote endpoint server over the Internet. 
     In another embodiment of the invention, a mobile wireless access point is provided. The mobile wireless access point includes at least one processor, memory and a cellular radio disposed within a housing, the cellular radio providing a broadband data connection to the Internet. The mobile wireless access point also includes a wireless router coupled to the processor, memory and cellular radio within the housing and configured to generate and maintain a wireless hotspot within a geographic distance of the housing and to route data from the wireless hotspot to the Internet over the broadband data connection. Finally, the mobile wireless access point can include a geolocation proxy module executing in the memory of the housing. The module includes program code enabled upon execution by the at least one processor in the housing to respond to a request from a computing device communicatively linked to the mobile wireless access point through the wireless hotspot for geolocation data, to obtain location data for the mobile wireless access point and to transmit the obtained location data to the one of the mobile devices over the wireless hotspot for use by the computing device in acquiring location based services from a remote endpoint server over the Internet. 
     Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.

     DETAILED DESCRIPTION OF THE INVENTION 
     Embodiments of the invention provide for mobile wireless access point geolocation services proxying for mobile devices. In accordance with an embodiment of the invention, a mobile wireless access point can establish a cellular data connection with a remote server over both a cellular communications network and the Internet. Also, the mobile wireless access point can establish a wireless hotspot through which different mobile devices can maintain a wireless communications link with respectively different hosts disposed about the Internet. Thereafter, the mobile wireless access point can perform geolocation in respect to the mobile wireless access point and provide a result set of geographic coordinates to requesting ones of the mobile devices within the hotspot so that location based services can be provided by the hosts to the mobile devices utilizing the geographic coordinates provided by the mobile wireless access point. 
     In further illustration,  FIG. 1  pictorially shows a computing architecture configured for mobile wireless access point geolocation services proxying for mobile devices. As shown in  FIG. 1 , a mobile wireless access point  100  can include a housing enclosing at least one processor  110 , memory  120 , a cellular radio  130 A and a wireless networking radio  130 B. The cellular radio  130 A can be configured to establish and maintain a cellular telephonic connection to a cellular network  190 A and to process data communications therethrough from the mobile wireless access point  100  to one or more remote endpoint servers  160  disposed about the Internet  190 B, by way of a network gateway  140 . 
     The wireless networking radio  130 B in turn can be configured to establish and maintain a wireless hotspot  170  within a limited geographic distance of the mobile wireless access point  100 . Within the hotspot  170 , short range wireless data communications can be managed between coupled computing devices  180 , for example laptop computers, personal computers, personal digital assistants, tablet computers, smartphones and the like. Further, within the hotspot  170 , data communications can be managed between individual ones of the computing devices  180  and the remote endpoint servers  160  through the cellular network  190 A and the Internet  190 B. 
     Of note, a geolocation proxy module  200 A can be disposed within the mobile wireless access point  100 , for example within firmware or other persistent memory of the mobile wireless access point  100 . The module  200 A can include program code that when loaded into memory  120  and executed by the processor(s)  110  is enabled to act as a proxy for geolocation of the computing devices  180 . Specifically, the program code can permit a subscription by individual ones of the computing devices  180  requiring geolocation proxying, and to respond to a request by one of the subscribing computing devices  180  for a geographic location by acquiring a geographic location  150  from a GPS receiver  200 B or by utilizing an alternate mechanism for acquiring a geographic location  150  such as RF location or computer protocol location. 
     Thereafter, the program code can provide the geographic location  150  to the requesting one of the computing devices  180 . The requesting one of the computing devices  180  in turn can provide the geographic location  150  to a corresponding one of theremote endpoint servers  160  in order to receive from the corresponding one of the remote endpoint servers  160  location based services. 
     In yet further illustration of the operation of the program code of the geolocation proxy module  200 A,  FIG. 2  is a flow chart depicting a process for mobile wireless access point geolocation services proxying for mobile devices. The process can begin in block  210  with the accessing by a mobile computing device of a remote endpoint server by way of a mobile access point. In block  220 , the remote endpoint server can offer location based services to the mobile computing device. In block  230 , mobile computing device can receive the offer of location based services and in block  240  can request location data, for example GPS coordinates, from the mobile wireless access point. In block  250  the mobile wireless access point can acquire the requested location data, for example through a GPS receiver or by way of RF location or computer protocol location, and in block  260  the location data can be returned to the mobile computing device. 
     In block  270 , the location data received from the mobile wireless access point can be in turn provided to the remote endpoint server by way of the mobile wireless accessing point. In block  280  the remote endpoint server can process the received location data in order to provide location based services to the mobile computing device. Finally, in block  290 , the mobile computing device can receive the location based services provided by the remote endpoint server.
