## Title
Tailoring content to be delivered to mobile device based upon features of mobile device

## Abstract

A system and computer program product for delivering tailored specific content to a mobile device. A shim application is provided to the mobile device by a content server after the mobile device visits the content server for the first time. The shim application detects the capabilities of the mobile device, such as the screen size, screen resolution, memory size, browser capabilities, etc. The shim application then includes such information in the header of the requests, such as a request for content, sent from the mobile device to the content server. The content server then generates the requested content in the appropriate format based on the information provided in the header. In this manner, the content server will now be able to ensure that the content provided by the content server for a particular mobile device will be appropriately displayed on the mobile device.

## Background
TECHNICAL FIELD
The present invention relates to mobile communications, and more particularly to tailoring the content delivered to a mobile device based upon the features of the mobile device.
BACKGROUND
In the marketplace, there are currently numerous different types of mobile devices. Mobile devices include mobile or cellular phones, smart phones, personal digital assistants (“PDAs”), palmtop computers, laptop computers and the like. These mobile devices function as wireless communication devices via a wireless communication link (GSM, GRPS, 3G, CSMA and the like) and access content over a wireless network infrastructure.
Each of these mobile devices may include different variations and features, such as web browser(s), as part of their platform. As a result, there may be difficulty in delivering content in an appropriate format to a great number of these mobile devices due to their varying features, such as varying mobile web browsers. For example, the content may not be able to be rendered appropriately on some of these mobile devices since the content provider may not be transmitting content in a format compliant with their web browsers.
The World Wide Web Consortium (“W3C”) has attempted to address this problem by adopting the Composite Capabilities/Preference Profile (“CC/PP”). The CC/PP is a specification for defining capabilities and preferences of user agents, where a user agent may refer to a client application implementing a network protocol used in communications within a client-server distributed computing system. With the CC/PP, a repository is created that maps the user agent to a set of features that are supported for that mobile device. However, the repository must be constantly updated in order to ensure that the mapping is up-to-date.
An additional attempt to address the difficulty in delivering content in an appropriate format to a great number of mobile devices with varying features is to have the mobile devices contain all of the possible libraries for the various mobile browser vendors thereby ensuring that the content is rendered on the mobile device appropriately. However, requiring the mobile devices to contain all of the possible libraries for the various mobile browser vendors is burdensome. Furthermore, the libraries would constantly need to be updated to ensure they are up-to-date.
Hence, there has not been an effective solution to delivering content in an appropriate format to a great number of mobile devices due to their varying features, such as varying mobile web browsers.

As stated in the Background section, mobile devices may include different variations and features, such as web browser(s), as part of their platform. As a result, there may be difficulty in delivering content in an appropriate format to a great number of these mobile devices due to their varying features, such as varying mobile web browsers. For example, the content may not be able to be rendered appropriately on some of these mobile devices since the content provider may not be transmitting content in a format compliant with their web browsers. Currently, there has not been an effective solution to delivering content in an appropriate format to a great number of mobile devices due to their varying features, such as varying mobile web browsers.
The principles of the present invention provide an improved technique for delivering content in an appropriate format to various mobile devices with varying platforms by having the content server deliver specifically tailored content to each mobile device as discussed below in connection with FIG. 4. FIG. 4 is a flowchart of a method for delivering tailored specific content to a mobile device.
As stated above, FIG. 4 is flowchart of a method for delivering tailored specific content to a mobile device 101 (FIGS. 1 and 2) in accordance with an embodiment of the present invention.
Referring to FIG. 4, in conjunction with FIGS. 1-3, in step 401, content server 102 detects a visit to server 102 by mobile device 101.
In step 402, a determination is made by server 102 as to whether the visit by mobile device 101 is a first time visit. If the visit is not a first time visit, then content sever 102 continues to monitor a visit by a subsequent mobile device 101 in step 401.
If, however, content server 102 detects a first time visit by mobile device 101, then, in step 403, content server 102 provides a shim application to mobile device 101. A shim application refers to a small library which transparently intercepts an application programming interface of mobile device 101, changes the parameters passed, handles the operation itself or redirects the operation elsewhere. “Providing the shim application,” as used herein, includes any means for the shim application to be provided to mobile device 101, including having content server 102 directly transmit the shim application to mobile device 101 as well as having content server 102 transmit a link to a website to download the shim application. In one embodiment, the shim application will be specific to mobile device 101 and will act as a client side proxy application. In one embodiment, the shim application will be configured as part of the installation.
In step 404, the user of mobile device 101 installs the shim application on mobile device 101. Once installed, in step 405, the shim application will detect the capabilities of mobile device 101. For example, the shim application can detect one or more of the following capabilities: screen size, screen resolution, memory size, browser capabilities, and the like. This list is not intended to be limiting but to provide examples of information that may be used to determine the capabilities of mobile device 101 so that content server 102 appropriately formats the content to be appropriately displayed on mobile device 101. Embodiments of the present invention cover any such information regarding the capabilities of mobile device 101 that may be used by content server 102 to appropriately format the content to be appropriately displayed on mobile device 101.
In step 406, the information regarding the capabilities of mobile device 101 detected by the shim application is stored in a cache (not shown in FIG. 2) of mobile device 101. The cache may be located internal within processor 201 or located external to processor 201. The cache may be any type of cache (e.g., physically indexed, physically tagged; virtually indexed, virtually tagged; virtually indexed, physically tagged).
In step 407, content server 102 receives a request for content from mobile device 101, where the request includes header information that provides content server 102 with the features or capabilities mobile device 101 supports, such as the capabilities detected in step 405. In one embodiment, the shim application adds the header information to the beginning of the data (i.e., request) being transmitted to content server 102, where the header information is obtained from the cache of mobile device 101.
In step 408, content server 102 processes the request. In step 409, content server 102 generates specific content to be delivered to mobile device 101 based on the received header information thereby ensuring that the content is formatted in a manner so that it will be appropriately displayed on mobile device 101. By content server 102 receiving information regarding the capabilities of mobile device 101 via the header information, content server 102 will now be able to ensure that the content provided by content server 102 for a particular mobile device 101 will be appropriately displayed on mobile device 101.
In step 410, content server 102 transmits the content generated in step 409 to mobile device 101.
In some implementations, method 400 may include other and/or additional steps that, for clarity, are not depicted. Further, in some implementations, method 400 may be executed in a different order presented and that the order presented in the discussion of FIG. 4 is illustrative. Additionally, in some implementations, certain steps in method 400 may be executed in a substantially simultaneous manner or may be omitted.
An example of a program using the principles of the present invention includes a program for generating charts and gauges which can be generated either on the client-side or on the server-side. The determination as to whether the program generates the charts and gauges on either the client-side or on the server-side can be determined based on the memory capabilities of mobile device 101, which is obtained from the shim application.
The descriptions of the various embodiments of the present invention have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
