DETAILED DESCRIPTION
FIG. 1 is a system diagram illustrating communication system 100. Communication system 100 includes wireless communication system 110, wireless communication device 120, primary content provider 130, and supplemental content provider 140. Wireless communication system 110 and wireless communication device 120 communicate over wireless link 150. Wireless communication system 110 and primary content provider 130 communicate over link 151. Wireless communication system 110 and supplemental content provider 140 communicate over link 152. In FIG. 1, wireless communication system 110 includes control system 111 and access system 113, which are communicatively coupled to each other in this example. Control system 111 includes data structure 112 in this example.
FIG. 2 is a flow diagram illustrating a method of operation of wireless communication system 110. The operations of FIG. 2 are referenced herein parenthetically. In FIG. 2, wireless communication system 110 receives (201) a registration request from wireless communication device 120. The registration request could include a request to initiate a communication session with wireless communication system 110, handoff messaging for transferring service from a coverage area of wireless communication system 110 to another coverage area of wireless communication system 110, an initial registration of wireless communication device 120 with wireless communication system 110 after a device power-on, or other registration requests. In this example, access system 113 includes equipment and systems to provide wireless access to communication services for wireless communication devices, such as wireless communication device 120 over wireless link 150. Wireless communication device 120 could communicate with systems or equipment of access system 113 to transfer the registration request.
In response to the registration request, wireless communication system 110 monitors (202) device status and updates a data structure with device status data for wireless communication device 120. In this example, control system 111 monitors the device status in response to access system 113 receiving a registration request from wireless communication device 120. Control system 111 updates data structure 112 with the device status data for wireless communication device 120, although in other examples, access system 113 or data structure 112 could include equipment and systems to monitor the device status and update data structure 112 with the device status data. In this example, the device status is associated with a present location of wireless communication device 120, and the device status data includes a representation of the present location. As wireless communication device 120 moves, the present location is monitored by wireless communication system 110 and the device status data is updated in data structure 112. In other examples, the device status data could include a present time, an identifier of a wireless access node associated with wireless communication device 120, a sector location of wireless communication device 120, a velocity of wireless communication device 120, a device type of wireless communication device 120, a present RF signal quality associated with wireless communication device 120, or information associated with wireless link 150, including combinations thereof.
Wireless communication system 110 receives (203) a content request from wireless communication device 120 for primary content from a primary content provider. The content request could include a request by wireless communication device 120 for user content from a content provider, such as a data request, voice call, voice over Internet protocol (VoIP) call, web page, video stream, audio stream, or other content or communication session request. Access system 113 could receive the content request, and transfer the content request to control system 111 in some examples. In further examples, wireless communication system 110 transfers the content request for delivery to primary content provider 130 over link 151. Primary content provider 130 receives the content request transferred over link 151 in this example, however, it should be understood that link 151 could include intermediary links, such as the Internet, or other networks, links, or systems. The content request could include a content request unrelated to the registration request from wireless communication device 120 in operation 201. For example, a voice call or handoff could initiate the registration request, while a data session could initiate a content request unrelated to the voice call, although from the same wireless communication device.
In response to the content request, wireless communication system 110 determines (204) an anonymous key associated with wireless communication device 120 and transfers the anonymous key for delivery to supplemental content provider 140. In this example, the anonymous key is determined to be associated with wireless communication device 120, while maintaining anonymity of wireless communication device 120 or a user of wireless communication device 120. The anonymous key could be determined by hashing, encrypting, obfuscating, randomizing, or otherwise rendering anonymous or quasi-anonymous an identifier associated with wireless communication device 120, including combinations thereof. In other examples, the anonymous key could be generated by wireless communication system 110 and subsequently assigned as an anonymous key associated with wireless communication device 120. Supplemental content provider 140 receives the anonymous key transferred over link 152 in this example, however, it should be understood that link 152 could include intermediary links, such as the Internet, or other networks, links, or systems.
Wireless communication system 110 receives (205) a device status request comprising the anonymous key transferred by supplemental content provider 140, and in response, transfers the device status data from data structure 112 for delivery to supplemental content provider 140. In this example, the device status request, transferred by supplemental content provider 140, is received over link 152 by control system 111 or other systems associated with data structure 112. The device status data is responsively transferred for delivery to supplemental content provider 140 over link 152. As discussed above, the device status data is data associated with a present location of wireless communication device 120, and could include other information associated with wireless communication device 120. In typical examples, the device status data does not reveal an identity of the user of wireless communication device 120, or an identity of wireless communication device 120, through the anonymous key associated with wireless communication device 120. This anonymous key allows supplemental content provider 140 to obtain information about wireless communication device 120 without obtaining an identity of wireless communication device 120. An identity of wireless communication device 120 or user of wireless communication device 120 could include a phone number, network access identifier (NAI), electronic serial number (ESN), mobile equipment identifier (MEID), personal name, or billing address, among other information identifying a person or actual physical device.
Wireless communication system 110 receives (206) supplemental content transferred by supplemental content provider 140 responsive to the transferred device status data. The supplemental content, as transferred for delivery to wireless communication system 110 by supplemental content provider 140, is received over link 152, although other configurations could be employed. The supplemental content could include emergency notifications, advertising content, weather alerts, or network alerts, among other supplemental content. In some examples, the supplemental content is of a similar format or data type as the primary content requested from primary content provider, such as web pages, streaming content, audio information, video content, among other content types. In typical examples, the supplemental content is selected by supplemental content provider 140 responsive to the device status data, such as location-based supplemental content, device-type based supplemental content, or supplemental content related to both a present time and location of wireless communication device 120, among other selections responsive to the device status data.
Wireless communication system 110 receives (207) the primary content transferred by primary content provider 130. In this example, the primary content is received over link 151, although other configurations could be employed. The primary content includes the content requested by wireless communication device 120 or a user of wireless communication device 120 as described in operation 203. It should be understood that the primary content could be received at a varying time with respect to the supplemental content.
Wireless communication system 110 transfers (208) the primary content and the supplemental content to wireless communication device 120. In this example, the primary content and the supplemental content are transferred over wireless link 150. The primary content includes content responsive to the primary content request, while the supplemental content includes content responsive to the device status data. Wireless communication system 110 could combine the primary content with the supplemental content for transfer to wireless communication device 120. For example, if a web page was requested in the primary content request, the supplemental content could include advertising content and wireless communication system 110 could transfer the requested web page along with advertising content to wireless communication device 120 responsive to the primary content request. In further examples, the supplemental content is integrated into streaming content, such as streaming video content, animations, or streaming audio content for playback on wireless communication device 120. In yet further examples, the supplemental content can supercede or interrupt the primary content, such as when the supplemental content includes weather or emergency alerts.
FIG. 3 is a system diagram illustrating communication system 300. Communication system 300 includes control system 310, packet data switching node/home agent (PDSN/HA) 312, content server 313, base station 320, wireless communication device (WCD) 330, Internet 340, advertisement provider 350, and web content provider 360. Wireless communication device 330 and base station 320 communicate over wireless link 370. In this example, wireless access is provided by base station 320 to wireless communication device 330 using the Evolution Data Optimized (EV-DO) wireless protocol over wireless link 370, although other wireless communication protocols could be employed. PDSN/HA 312 communicates with base station 320 over link 371, a T1 backhaul link capable of carrying Internet protocol (IP) packets. Content server 313 and PDSN/HA 312 communicate over link 372, a local-area Ethernet network link. Control system 310 and PDSN/HA 312 communicate over link 373, a local-area Ethernet network link. Content server 313 and advertisement provider 350 communicate over Internet 340 and IP links 374 and 377. Content server 313 and web content provider 360 communicate over Internet 340 and IP links 374 and 376. Control system 310 and advertisement provider 350 communicate over Internet 340 and IP links 375 and 377 in this example.
PDSN/HA 312 includes equipment and systems for routing communications between base station 320 serving wireless communication devices and other systems, such as Internet 340 and content server 313. PDSN/HA 312 also includes equipment for monitoring and transferring device status data to control system 310. Although PDSN/HA 312 is shown as a packet data switching node/home agent in this example, PDSN/HA 312 could also comprise equipment such as base station controllers, packet routers, bridges, network gateways, or mobile switching centers, among other equipment and systems. Content server 313 includes computer systems, routers, processing equipment, and computer-readable storage media, to provide primary and supplemental content received from advertisement provider 350 and web content provider 360 to wireless communication devices. Control system 310 includes computer systems in this example, comprising processing equipment and computer-readable storage media, to receive device status data from PDSN/HA 312 as well as store, retrieve, and transfer the device status data in database 311 associated with a wireless communication device or anonymous key. Communication system 300 could also comprise a radio access network (RAN), wireless access system, or further base stations, control systems, servers, and databases to provide wireless access to communication services for wireless communication devices over a geographic area.
FIG. 4 is a sequence diagram illustrating a method of operation of communication system 300. In FIG. 4, wireless communication device (WCD) 330 transfers a registration request to base station (BS) 320. In this example, the registration request is transferred by wireless communication device 330 over wireless link 370 in order to receive wireless access through base station 320, such as due to a device power-on or handoff from another base station. In other examples, the registration request includes a request to initiate a communication session with base station 320, such as a voice call, data session, email transfer, text message, video stream, audio stream, or other communication session. Base station 320 transfers this registration request to PDSN/HA 312. Responsive to the registration request, base station 320 and PDSN/HA 312 can coordinate with wireless communication device 330 to establish a communication session over wireless link 370, such as completing a registration or authentication process, assigning communication channels, frequencies, timeslots, or spreading codes for a communication session.
Also responsive to the registration request, PDSN/HA 312 monitors device status for wireless communication device 330 and transfers device status data related to the device status to control system 310 for storage in database 311. Although FIG. 4 shows the device status data being transferred to control system 310 during one instance, it should be understood that PDSN/HA 312 continues to monitor the device status of wireless communication device 330 and transfer associated device status data to control system 310. Control system 310 then stores the device status data in database 311 for later retrieval in a computer-readable storage medium, such as a hard drive, server, solid-state storage device, random-access memory, or memory cache, among other equipment. The device status data for wireless communication device 330 could be stored in database 311 according to an identifier associated with wireless communication device 330. In some examples, the identifier associated with wireless communication device 330 in database 311 reveals an identity of wireless communication device, such as a user name, phone number, network access identifier (NAI), electronic serial number (ESN), mobile equipment identifier (MEID), or other identifier associated with a person or physical device. In other examples, a pseudorandom identifier or an anonymous identifier is generated and used to associate the device status data with wireless communication device 330 in database 311 to protect an identity of a user or physical device.
The device status data could include information as discussed in FIG. 2 above, among other information. For example, the device status data could be associated with a present location of wireless communication device 330, and include a digital representation of the present location. A present location of wireless communication device 330 could include a present sector, present wireless coverage area, serving base station, geographic coordinates, or other location information. In other examples, the device status data could include a present time, a time in a present wireless coverage area, a time of entry into a present wireless coverage area, a velocity of wireless communication device 330, a device type of wireless communication device 330, a present RF signal quality associated with wireless communication device 330, or information associated with wireless link 370, including combinations thereof.
Base station 320 receives a content request from wireless communication device 330, and transfers the content request to PDSN/HA 312. PDSN/HA 312 transfers the content request to content server 313. In other examples, base station 320 transfers the content request to content server 313. In response to the content request, PDSN/HA 312 transfers a content notice to control system 310. The content notice indicates a content request is pending and could include information found in the content request, information about wireless communication device 330, or comprise the content request. The content request could be related or unrelated to the registration request transferred by wireless communication device 330. In this example, the content request includes a website address, such as an IP address, of a desired web page. In other examples, the content request could include a network address, streaming media channel identifier, telephone number, user identifier, user credentials, among other content or user identifiers. The content request indicates wireless communication device 330 desires content from a primary content provider, such as web content provider (web provider) 360 in this example. Content server 313 transfers the content request for delivery to web content provider 360, over Internet 340, although other systems may be involved in transferring the content request. In response to the content request, web content provider 360 determines web content for delivery to wireless communication device 330, and transfers the web content. Although FIG. 4 shows the web content being transferred shortly after the web content is determined by web content provider 360, it should be understood that the web content could be transferred at other times, as in examples when the web content requires additional time to be determined and transferred.
In response to the content notice, control system 310 determines an anonymous key to be associated with wireless communication device 330. In this example, the anonymous key is determined by applying a hashing process to the electronic serial number (ESN) of wireless communication device 330. The hashing process determines an identifier unrelated to the ESN to represent the ESN in an anonymous manner, such as generating a random or pseudorandom number based upon the ESN or other data, and then associating the hashed ESN with wireless communication device 330. The anonymous key allows wireless communication device 330 to be identified in an anonymous manner without revealing an actual identity of wireless communication device 330 or a user of wireless communication device 330. In some examples, the key is predetermined and assigned to wireless communication device 330 upon receipt of the content notice, while in other examples, the key is calculated in response to the content notice.
Once the key has been determined, control system 310 transfers the key for delivery to advertisement provider (ad provider) 350 over links 375 and 377 through Internet 340. Control system 310 associates the key with the device status data stored in database 311 for wireless communication device 330. In some examples, the key is added to database entries or referenced to database entries for the device status data for wireless communication device 330. In other examples, control system 310 determines the key when the device status data is begun to be stored in database 311, and transfers the key to ad provider 350 in response to the content notice. Ad provider 350 receives the key transferred by control system 310, over Internet 340 in this example. In response to the key transferred by control system 310, ad provider 350 transfers a device status request for delivery to control system 310. The device status request indicates a request for device status data for a wireless communication device, and includes a key as transferred to ad provider 350. In some examples, other systems in communication system 300 receive the device status request and transfer the device status request to control system 310, such as content server 313.
In response to the device status request transferred by ad provider 350, control system 310 transfers the device status data for the wireless communication device indicated by the key accompanying the device status request. Control system 310 transfers the device status data for delivery to ad provider 350 over Internet 340. In some examples, the key accompanies the device status data transferred for delivery to ad provider 350, to differentiate the device status data as being associated with the requested wireless communication device status data, such as wireless communication device 330, instead of a different wireless communication device. In examples with multiple wireless communication devices, ad provider 350 could concurrently transfer multiple device status requests for the multiple wireless communication devices as well as receive responses to the multiple requests. As discussed above, the device status data could include location or time-based information for wireless communication device 330, among other information. In this example, the device status data does not reveal an actual identity of wireless communication device 330, such as an identity of a user or actual physical device, and thus the identity of wireless communication device 330 is kept relatively anonymous from ad provider 350. However, the device status data does reveal information about wireless communication device 330 which allows ad provider 350 to make intelligent ad content choices based on the device status data.
Ad provider 350 then determines ad content based on the device status data for wireless communication device 330. This ad content could include ad content based on a present location, a time in a present location, a device type, brand, or model, or other information in the device status data for wireless communication device 330. The present location could indicate a present sector, base station, geographical coordinates, velocity or speed, among other location-based information for wireless communication device 330. A device type, model, or brand could be used to determine the ad content, such as determining a first ad content for users of a first model of wireless communication device, and a different ad content for users of other models of wireless communication devices. Time-based information in the device status data could also be used to determine the ad content. In examples of time-based information, the device status data could include a time of a wireless communication device is present in a sector of wireless coverage. Ad provider 350 could determine a first ad content for a wireless communication device which has recently entered into a new sector of wireless coverage, as indicated by the device status data transferred to ad provider 350 for that wireless communication device. A second ad content could be determined for a wireless communication device which has lingered in a sector of wireless coverage for a period of time greater than the recent wireless communication device. Different ad content could also be delivered to a single wireless communication device at different times while present in a single sector of wireless coverage, such as a first ad content when the wireless communication device makes a content request when newly entering the sector, and a second ad content when the wireless communication device makes a content request after remaining in the sector for a predetermined time. Ad provider 350 could pay different prices for ad content served to wireless communication devices based on the device status data, such as paying more for ads served to new wireless communication devices in a sector of wireless coverage, and paying less for ads served to wireless communication devices which linger in a sector of wireless coverage. Other examples of ad cost differentials could be determined, such as based on device model, past device status data, or other considerations. Other ad content determinations based on the device status data could be provided, including combinations thereof.
Additionally, the key transferred by control system 310 could be associated with wireless communication device 330 for only the present content request, such as a dynamic key which is re-determined for each content request. In other examples, the key transferred by wireless communication device 330 could be associated with wireless communication device 330 for a longer duration than the dynamic key, such as a static key for multiple content requests. In examples where a static key is employed, control system 310 or ad provider 350 could retain long-term device status data for wireless communication device 330, and ad provider 350 could determine ad content in response to present device status data as well as upon past transferred device status data from previous content requests. For example, long term device status data which indicates frequent visits within a particular wireless coverage area could trigger ad content based upon the long term visitation to that particular wireless coverage area by ad provider 350.
Once the ad content is determined by ad provider 350, the ad content is transferred by ad provider 350 for delivery to content server 313. The ad content is transferred over Internet 340 in this example. The key could accompany the ad content to associate the ad content with wireless communication device 330, or other identifiers could be used to associate the ad content with the device status data, such as a transaction identifier or network identifier. Control system 310 could also transfer the key to content server 313, among other information.
After receiving both the supplemental content, namely the ad content, and the primary content, namely the web content, content server 313 transfers the ad content and web content for delivery to wireless communication device 330 through base station 320. In this example, the primary content includes content responsive to the primary content request, while the supplemental content includes content responsive to the device status data. In some examples, the ad content and web content are merged into the content type of the primary content, such as when a banner advertisement from ad provider 350 accompanies a web page from web provider 360. In other examples, a separate ad content type than the primary content type is provided, such as when a streaming video content is received from web content provider 360 and a static overlay ad is provided by ad provider 350. A type of the primary content, as originally requested in the content request, could also be provided to ad provider 350 to allow ad provider 350 to select an ad content type based upon the primary content type. It should be understood that the ad content and the web content could be transferred at different times by content server 313 for delivery to wireless communication device 330. Web browser, rendering software, or media player applications of wireless communication device 330 could then merge the primary content with the supplemental content after receiving the web content and ad content from base station 320.
