System and method for cross-carrier mobile device capability discovery

Abstract

A system and method for cross-carrier mobile device capability discovery. According to an embodiment, a content delivery platform receives an identifier associated with a mobile computing device of a user, identifies a wireless carrier associated with the mobile computing device based on the received identifier, and detects one or more media capabilities supported by the user's mobile computing device for delivering content to the user's mobile computing device based at least in part on media capabilities supported by the identified carrier.

Description

BACKGROUND OF THE INVENTION

Media capabilities supported by mobile computing devices, such as those that receive wireless service and display content delivered via that service, and the wireless carriers that provide their service, are becoming increasingly diverse and rich. For example, the following media delivery methods and types are generally available:

• • MMS (Multimedia Messaging Service)—video+txt
  • MMS (Multimedia Messaging Service)—image+txt
  • WAP (Wireless Application Protocol)—video+txt/image+txt
  • SMS (Short Message Service )—txt alerts only

However, different wireless carriers support different media delivery methods, and different mobile devices support different types of displayable media. Thus, it is quite difficult for content providers, especially those not affiliated with carriers, to know whether the content they provide can even be displayed by users' mobile devices, much less in a format appropriate to the device's capabilities.

Accordingly, there is a need in the art for a system and method to provide displayable content to users' mobile devices with more certainty.

DETAILED DESCRIPTION

The present invention addresses the uncertainty of providing displayable content to a user's mobile device by using knowledge of media capabilities supported by the device's carrier to detect the devices' media capabilities.

A carrier specific sequence of events enables a content delivery platform to determine the most rich media type (e.g., SMS/MMS/Video) and delivery method (e.g., SMS/WAP Push/MMS) for each mobile device user based upon applicable carrier policies and network capabilities, as well as the mobile device's make and model. Once captured, this information is saved to a participating customer capabilities database, which can be updated automatically if the platform detects a newer mobile device model.

FIG. 1 depicts a content distribution system in accordance with an embodiment of the present invention. The delivery platform (120) upon which the content distribution system is based includes a discovery engine 130, database (140), and delivery engine (150). FIG. 2 describes a process associated with the discovery phase (100) of the content distribution system, and FIGS. 3-4 describe carrier specific processes for detecting the media capability of a mobile device.

In the discovery phase (100), the delivery platform (120) receives (step 200) an identifier (112) associated with a mobile computing device of a user (110) across a network (115), such as a telephone number, and issues a carrier request (162) across the network (115) to a look-up engine (160) to identify (210) the wireless carrier associated with the mobile computing device based on the received identifier.

Upon receiving the carrier response (164) with the carrier information, the discovery engine (130) detects (220) one or more media capabilities supported by the user's mobile computing device for delivering content to the user's mobile computing device based at least in part on media capabilities supported by the identified carrier, as described in carrier-specific embodiments in FIGS. 3-4 discussed below.

The discovery engine (130) may then generate a descriptor (135) associated with one of the detected media capabilities and store it in the database (140). The stored descriptor (135) may be associated with the richest of the detected media capabilities, for example.

In the delivery phase (105), the delivery engine (150) may retrieve the stored descriptor, and deliver content to the user's mobile computing device in accordance with the media capability associated with the stored descriptor (135). In an embodiment of the invention, the delivery engine (150) may retrieve content (145) stored in a format native to the delivery platform (120), and transform it to a favorable delivery format (165) tailored to the user's device based upon the information in the descriptor (135).

FIG. 3 is a flow chart that depicts a carrier specific process for detecting media capability of a mobile device in accordance with an embodiment of the present invention. For example, carrier “A” may be known to include only MMS support including images and txt, and not “out-of-garden” WAP pushes. In this situation, a richer media technology message, such as an MMS message, may be sent (step 300) to the user's mobile device. If an automated response (step 310) from the device is “Retrieved” (e.g., via an MMS delivery report), the discovery engine (130) may log (step 320) the device as “MMS Capable” in the database (140). If the MMS cannot be received by the device, a status message of “Indeterminate” would be received automatically by the engine (130), which would log (step 330) a status of indeterminate and indicate that the user (110) receive only poorer media technology content (e.g., SMS alert messages).

FIG. 4 is a flow chart that depicts another carrier specific process for detecting media capability of a mobile device in accordance with an embodiment of the present invention. For example, carrier “B” may be known to not support MMS, but to support “out-of-garden” WAP pushes. For users of carrier “B”, WAP can be considered the media richest format for alert reception. The user (110) may be sent (step 400) a WAP Push message as well as a clickable SMS WAP link, for example. This is to obtain the highest response rate for those users that may be unfamiliar with their device's WAP deck. If the user (110) clicks (step 410) on either link (WAP Push or SMS) within an allotted timeframe (e.g., five minutes), the discovery engine (130) may use (step 420) this information to obtain device information (e.g., via HTTP header information, such as the “user-agent” field) and log the information into the database (140). If the user (110) does not respond to either WAP link within the allotted time, the database (140) may be updated (step 430) to reflect that they will receive only poorer media technology (e.g., SMS messages).

Preceding steps 300 and 400 in embodiments of the present invention in which the user (110) desires to subscribe to a content service provided by the platform (120), the discovery engine (130) may receive the mobile device identifier (112) from the user (110) via a web site, at which time the engine (130) may send a poorer technology message (e.g., SMS message) to the user's mobile device containing a PIN for verification purposes. When the user (110) provides verification by entering the PIN via the web site, steps 300 and 400 may follow. This also verifies to the platform that the user (110) understands how to use the poorer technology features of the mobile device.

In other embodiments, the process of the user (110) subscribing to a content service may originate from the user (110) entering a keyword and specific short code in the device and sending it to the device's carrier, which can operate in conjunction with the platform (120) to cause the further subscription steps described above to be carried out.

FIG. 5 illustrates the components of a basic computing device in accordance with an embodiment of the present invention, which may include a server running the discovery engine (130) or delivery engine (150), for example. The computing device may be a personal computer, workstation, server, or any other type of microprocessor-based device.

The storage (540) may include volatile and nonvolatile data storage, including one or more electrical, magnetic or optical memories such as a RAM, cache, hard drive, CD-ROM drive, tape drive or removable storage disk. The communication device (560) may include a modem, network interface card, or any other device capable of transmitting and receiving signals over a network. The components of the computing device may be connected in any manner, such as via electrical bus or wirelessly.
