DETAILED DESCRIPTION OF THE INVENTION

P-0020[0020] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that these specific details need not be used to practice the present invention. In other instances, well-known structures, interfaces, and processes have not been shown in detail in order not to unnecessarily obscure the present invention.

P-0021[0021]FIG. 1 illustrates a smart area system according to an embodiment of the invention. Static nodes <b>110</b><i>a . . . . n </i>and mobile nodes <b>110</b><i>a . . . n </i>define one or more smart areas <b>105</b>. The smart areas <b>105</b> may overlap. The smart areas <b>105</b> are areas where electronic services that can be personalized and localized are provided. The electronic services may be provided to users using mobile nodes <b>120</b><i>a . . . m</i>. The static nodes <b>110</b><i>a . . . n </i>and the mobile nodes <b>120</b><i>a . . . m </i>may be connected via a wireless network <b>130</b>.

P-0022[0022] Also connected to the wireless network <b>130</b> is a smart area manager <b>140</b>, a database <b>150</b>, and one or more other systems <b>155</b>. Alternatively, the smart area manager <b>140</b> may be connected to the wireless network <b>130</b> via another network, such as a local area network and/or wide area network (e.g., the Internet). The database <b>150</b> may provide information in response to a user request from, for example, the mobile node <b>120</b><i>a </i>in one of the smart areas <b>105</b>. It will be apparent to one of ordinary skill in the art that the database <b>150</b> or any other data source (e.g., web page, etc.) may be operable to provide information in response to a user request in the system <b>100</b>. Also, information regarding a user in one of the smart areas <b>105</b> may be provided to one or more external systems <b>155</b> that utilize the information. An external system <b>155</b>, for example, may include an advertising system that provides localized advertising to the relevant smart area. The advertising can be personalized, such as advertisements for products or services that the user is interested in. Alternatively, an external system <b>155</b> may provide-information regarding products or services in a smart area. These and other external systems may be used in the system <b>100</b>.

P-0023[0023] The static nodes <b>110</b><i>a . . . n </i>provide location information for defining the borders of the smart areas <b>105</b>. In one embodiment, the static nodes <b>110</b><i>a . . . n </i>may be computer-based nodes executing location software for defining borders for the smart areas <b>105</b>. The static nodes <b>110</b><i>a . . . n </i>may communicate with each other to generate a coordinate system, such as X and Y borders that may be used to create the smart areas <b>105</b> therein. The coordinate system may have greater than two dimensions (e.g., latitude, longitude, and altitude). When a mobile node (e.g., one of the mobile nodes <b>120</b><i>a . . . m </i>or trusted mobile node <b>170</b>) enters the coordinate system, the mobile node communicates with one or more of the static nodes <b>110</b><i>a . . . n </i>to get its location (i.e., location information) within the coordinate system. This location information may be transmitted to the smart area manager <b>140</b> to create a smart area or to invoke smart area services. In other embodiments, location information for a user may be determined using known algorithms executed by the static nodes <b>110</b><i>a . . . n</i>. Each static node may be placed at a location for an extended period of time.

P-0024[0024] The mobile nodes <b>120</b><i>a . . . m </i>and the trusted mobile node <b>170</b> may include conventional portable wireless devices (e.g., cellular phones, personal digital assistants, laptops, etc.). The mobile nodes <b>120</b><i>a . . . m </i>are operable to transmit information (e.g., location information of the mobile node), information related to the user of the mobile node, and/or a request for information related to one of the smart areas <b>105</b> being occupied by the user.

P-0025[0025] The smart area manager <b>140</b> may include one or more servers or the like operable to be connected to the wireless network <b>130</b>, the database <b>150</b>, the system(s) <b>155</b>. The smart area manager <b>140</b> also includes an interface <b>145</b> for a system administrator <b>160</b>. In one embodiment, the interface <b>145</b> may include an interface that allows the system administrator to select nodes for defining a smart area. The system administrator <b>160</b> may use the trusted mobile node <b>170</b> to define a smart area, such as described in detail below. The trusted mobile node <b>170</b> is a mobile node known by the smart area manager <b>140</b> to be used for defining smart areas. For example, a secured connection may be established between the trusted mobile node <b>170</b> and the smart area manager <b>140</b>. The system administrator <b>160</b> may use the trusted mobile node <b>170</b> to provide location information for defining borders for a smart area.

P-0026[0026]FIG. 2A illustrates a data flow diagram <b>200</b> for the flow of data in the smart area system <b>100</b>, according to an embodiment of the invention. FIG. 2A is described with respect to an example, such as a user inquiring about products in one more of the smart areas <b>105</b>, for purposes of providing a clear understanding of the system <b>100</b>. It will be apparent to one of ordinary skill in the art that the system <b>100</b> may be used to request information about anything related to a smart area within the system <b>100</b>. Furthermore, information transmitted from a mobile device may not include a request and may simply include information about the user, such as for use with the systems <b>155</b>.

P-0027[0027] A user using the mobile node <b>120</b><i>a </i>scans a barcode of a wine bottle in one or more of the smart areas <b>105</b>. For example, the user may be in overlapping smart areas or a single smart area. User information and location information of the mobile node <b>120</b><i>a </i>(e.g., determined by one or more of the static nodes <b>120</b><i>a . . . n</i>) is transmitted to the smart area manager <b>140</b>. The user information includes, for example, a request <b>210</b> for information about the wine bottle. The user information may also include information about the user which can be used by an advertisement system (e.g., one of the systems <b>155</b>) for generating advertisements within the smart space currently occupied by the user and targeted at products of interest to the user.

P-0028[0028] The smart area manager <b>140</b> determines the smart area(s) <b>105</b> that the user is occupying based on the location information (<b>220</b>). For example, the smart area manager <b>140</b> stores the borders of the smart areas <b>105</b> and identifies which of the smart areas <b>105</b>, such as with overlapping smart areas, that the user is occupying based on the location information. If the user is in overlapping smart areas, a tree of the smart areas <b>230</b> may be used to identify policies associated with the overlapping smart areas.

P-0029[0029]FIG. 2B illustrates a user <b>205</b> (e.g., a user making the request <b>210</b> of FIG. 2A) in overlapping smart areas <b>105</b><i>a . . . d</i>. The smart area <b>105</b><i>a </i>is the largest and completely encompasses the smart areas <b>105</b><i>b . . . d</i>. The smart area <b>105</b><i>b </i>completely encompasses the smart areas <b>105</b><i>c </i>and <b>105</b><i>d</i>. The smart areas <b>105</b><i>c </i>and <b>105</b><i>d </i>have some overlap with each other. FIG. 2C illustrates a tree <b>215</b>, which is exemplary representation of the overlap of the smart areas <b>105</b><i>a . . . d </i>that the user <b>205</b> is occupying.

P-0030[0030] In the data flow diagram of FIG. 2A, the smart area manager <b>140</b> identifies one or more policies <b>250</b> for the tree of smart areas <b>230</b> and adds the policies <b>250</b> to the request. For example, the smart area manager <b>140</b> selects one or more of the policies <b>240</b> associated with the smart areas the user is occupying. In one embodiment, the policies <b>240</b> may be stored in a database (not shown) connected to the smart area manager <b>140</b>, and the smart area manager <b>140</b> retrieves relevant policies from the database.

P-0031[0031] A policy of the policies <b>240</b> may include a condition associated with a smart area. For example, the condition may be associated with one or more particular users or one or more available services/applications associated with the smart area. For example, the user requesting information about the wine bottle may be a preferred customer having access to print services that can be used to print pricing information. Thus, one of the identified policies <b>250</b> may include access to print services in the occupied smart area. Another example may include a security policy, where a particular user has security clearance within particular smart areas.

P-0032[0032] As described with respect to FIGS. 2B and 2C, a user may be occupying overlapping smart areas. Overlap policy information may be included in the policies <b>240</b> and identified by the smart area manager <b>140</b>. Overlap policy information may identify which policy has precedence when policies for overlapping smart areas conflict. For example, referring to FIG. 2B, the smart area <b>105</b><i>c </i>may have a policy giving the user <b>160</b> security clearance within the smart area <b>105</b><i>c</i>. The user may not have security clearance in the smart area <b>105</b><i>d </i>based on a policy associated with the smart area <b>105</b><i>d</i>. Overlap policy information for the smart area <b>105</b><i>d </i>may include not giving security clearance for any area overlapping smart area <b>105</b><i>d. </i>

P-0033[0033] In FIG. 2A, the user request and identified polices <b>260</b> are used to perform an action <b>270</b>, which may include providing requested information, providing an action on the environment, etc. For example, the action <b>270</b> may include retrieving information pertaining to the request (e.g., wine bottle price) from a data source (e.g., the database <b>150</b>) and transmitting the information to the user. The action <b>270</b> may also include providing one or more services through the systems <b>155</b>.

P-0034[0034] As described above, one or more smart areas <b>105</b> may be defined using the static nodes <b>120</b><i>a . . . n </i>in the system <b>100</b>. FIGS. <b>3</b>A-D illustrate defining smart areas according to an embodiment of the invention. In FIG. 3A, a plurality of static nodes <b>110</b><i>a . . . j </i>are placed for defining smart areas. The static nodes <b>110</b><i>a . . . j </i>may be placed at corners of smart areas being defined, or the static node <b>10</b><i>a . . . j </i>may be generally placed, such that the system administrator can select groups of the static nodes <b>110</b><i>a . . . j </i>for defining a smart area The static nodes <b>110</b><i>a . . . j </i>may communicate with each other to determine a coordinate system and provide location information within the coordinate system for each of the static nodes <b>110</b><i>a . . . j </i>to the smart area manager <b>140</b>.

P-0035[0035] In FIG. 3B, the system administrator <b>160</b> of FIG. 1 selects static nodes for defining a smart area. For example, as shown in FIG. 1, the smart area manager <b>140</b> includes the user interface <b>145</b>. The user interface <b>145</b> may include an interface allowing the administrator <b>160</b> to select static nodes for defining a smart area. Static nodes <b>110</b><i>a</i>, <b>110</b><i>b</i>, <b>110</b><i>e</i>, and <b>110</b><i>d </i>may be selected, for example, by the administrator <b>160</b> for defining a smart area <b>105</b><i>a</i>, shown in FIG. 3C. In one embodiment, the static nodes are selected in a particular order. For example, the first static node selected (e.g., the static node <b>110</b><i>a</i>) is a beginning point of a geometric figure approximately defining the border of the smart area being defined. The next static node selected (e.g., the static node <b>110</b><i>b</i>) is the next consecutive point on an outline or border of the geometric figure. Each point on the border may be a corner of the geometric figure approximately defining the border of the smart area being defined. The static nodes may be selected until the starting point (e.g., the static node <b>110</b><i>a</i>) is approximately reached. If the last static node selected is not approximately the starting point, then the smart area manager <b>140</b> may interpolate the remaining portion of the border.

P-0036[0036] In FIG. 3C, the smart area manager <b>140</b> defines the smart area <b>105</b><i>a </i>based on the selected static nodes. For example, the smart area manager <b>140</b> determines and stores the borders of the smart area <b>105</b><i>a</i>, such that the smart area manager <b>140</b> can determine when a mobile node enters the smart area <b>105</b><i>a</i>. Border information may include the location information of the static nodes <b>110</b><i>a</i>, <b>110</b><i>b</i>, <b>110</b><i>d</i>, and <b>110</b><i>e </i>and location information for a border of a corresponding geometric figure. FIG. 3D illustrates multiple smart areas <b>105</b><i>a . . . d </i>defined using the static nodes <b>110</b><i>a . . . j </i>shown in FIG. 3A.

P-0037[0037]FIG. 4 illustrates a method <b>400</b> for defining a smart area, according to the embodiment of the invention shown in FIGS. <b>3</b>A-D. In step <b>410</b>, static nodes (e.g., the static nodes <b>110</b><i>a . . . j</i>) are placed. The static nodes may be placed at the corners of smart areas being defined or generally placed. In step <b>420</b>, location information is determined for each static node. In step <b>430</b>, the location information is transmitted to the smart area manager <b>140</b>. In step <b>440</b>, static nodes (e.g., the static nodes <b>110</b><i>a</i>, <b>110</b><i>b</i>, <b>110</b><i>d</i>, and <b>110</b><i>e</i>) are selected for defining a smart area. In step <b>450</b>, the smart area (e.g., the smart area <b>105</b><i>a</i>) is defined based on the location of the selected static nodes. For example, a border of the smart area is determined based on the location information, such that electronic services may be provided to a user crossing the border and entering the smart area. In step <b>460</b>, one or more policies are linked to the defined smart area. Some or all of the steps in the method <b>400</b> may be repeated for defining multiple smart areas. For example, steps <b>420</b>-<b>460</b> may be repeated for each smart area being defined.

P-0038[0038] FIGS. <b>5</b>A-D illustrate defining a smart area according to another embodiment of the invention. FIG. 5A illustrates static nodes <b>110</b><i>a . . . e </i>placed, for example, by the administrator <b>160</b> of FIG. 1. The static nodes <b>110</b><i>a . . . j </i>may communicate with each other to determine a coordinate system and provide location information within the coordinate system for each of the static nodes <b>110</b><i>a . . . e </i>to the smart area manager <b>140</b>. The administrator <b>160</b> uses the trusted mobile node <b>170</b> to communicate with the smart area manager <b>140</b>.

P-0039[0039] As shown in FIG. 5B, the administrator <b>160</b> moves to a first corner <b>510</b> of a smart area being defined. At the first corner <b>510</b>, the administrator <b>160</b> transmits location information to the smart area manager <b>140</b>. Transmission of location information is repeated at each corner of the smart area being defined. FIG. 5C illustrates establishing location information for corners <b>520</b> and <b>530</b> of the smart area being defined. The administrator <b>160</b> sends a request to the smart area manager <b>140</b> to close the smart area being defined after sending location information for each corner <b>510</b>-<b>530</b>. Then, the smart area manager <b>140</b> defines a smart area <b>105</b><i>a</i>, shown in FIG. 5D, based on the location information for each corner. The border of the smart area <b>105</b><i>a </i>may represent geometric figures other than a triangle.

P-0040[0040]FIG. 6 illustrates a method <b>600</b> for defining a smart area, according to the embodiment of the invention shown in FIGS. <b>5</b>A-D. In step <b>610</b>, static nodes (e.g., the static nodes <b>110</b><i>a . . . e</i>) are placed. In step <b>620</b>, location information is determined for each static node.

P-0041[0041] In step <b>630</b>, the administrator <b>160</b> moves to a corner (e.g., the corner <b>510</b>) of the smart area being defined with the trusted mobile node <b>170</b> of FIG. 1. In step <b>640</b>, location information is determined for that corner. For example, the trusted mobile node <b>170</b> positioned at the corner obtains its location information from static nodes. In step <b>650</b>, the location information is transmitted to the smart area manager <b>140</b>.

P-0042[0042] In step <b>660</b>, the administrator <b>160</b> determines whether location information is needed for anymore corners of the smart area being defined. If more location information is needed, steps <b>630</b>-<b>660</b> are repeated. If no more location information is needed, the administrator <b>160</b> sends a request to the smart area manger <b>140</b> to close the smart area being defined (step <b>670</b>). In step <b>680</b>, the smart area is defined by the smart area manager <b>140</b>. For example, a border of the smart area is determined based on the location information, such that electronic services may be provided to a user crossing the border and entering the smart area. In step <b>690</b>, one or more policies are linked to the defined smart area. Some or all of the steps in the method <b>600</b> may be repeated for defining multiple smart areas. For example, steps <b>630</b>-<b>690</b> may be repeated for each smart area being defined.

P-0043[0043] FIGS. <b>7</b>A-D illustrate defining smart areas according to another embodiment of the invention. FIG. 7A illustrates static nodes <b>110</b><i>a . . . e </i>placed, for example, by the administrator <b>160</b>. The static nodes <b>110</b><i>a . . . e </i>may communicate with each other to determine a coordinate system and provide location information within the coordinate system for each of the static nodes <b>110</b><i>a . . . e </i>to the smart area manager <b>140</b>. The administrator <b>160</b> uses the trusted mobile node <b>170</b> to communicate with the smart area manager <b>140</b>.

P-0044[0044] As shown in FIG. 7B, the administrator <b>160</b> moves to a location <b>710</b> on a border of the smart area being defined. At the location <b>710</b>, the administrator <b>160</b> transmits location information to the smart area manager <b>140</b>. As shown in FIG. 7B, the administrator <b>160</b> walks along a path <b>720</b> corresponding to the border of the smart area being defined. As the administrator walks along the path <b>720</b>, the mobile node is periodically sending location information to the smart manager <b>140</b>. As shown in FIG. 7C, the administrator <b>160</b> continues to transmit location information along the path <b>720</b> until a location <b>730</b> is reached. The location <b>730</b> may be the same or approximately the same as the location of the location <b>720</b>. Alternatively, the location <b>730</b> may be distanced from the location <b>720</b>. An interpolation process, such as computing a closest geometric figure, may be used to complete the path <b>720</b>. The administrator <b>520</b> sends a request to the smart area manager <b>140</b> to close the smart area being defined after sending location information at the location <b>730</b>. Then, the smart area manager <b>140</b> defines the smart area <b>105</b><i>a</i>, shown in FIG. 7D, by computing the closest geometric figure matching the path <b>720</b>. Algorithms known in the art may be used for computing the closest geometric figure.

P-0045[0045]FIG. 8 illustrates a method <b>800</b> for defining smart areas, according to the embodiment of the invention shown in FIGS. <b>7</b>A-D. In step <b>810</b>, static nodes (e.g., the static nodes <b>110</b><i>a . . . e</i>) are placed. In step <b>820</b>, location information is determined for each static node.

P-0046[0046] In step <b>830</b>, the administrator <b>160</b> moves to a location on a border of the smart area being defined with the trusted mobile node <b>170</b> of FIG. 1. In step <b>840</b>, location information is determined for that location on the border. For example, the trusted mobile node <b>170</b> positioned at the location on the border obtains its location information from static nodes. In step <b>850</b>, the location information is transmitted to the smart area manager <b>140</b>.

P-0047[0047] In step <b>860</b>, the administrator <b>160</b> moves along a path corresponding to the border of the smart area being defined and simultaneously transmits location information for the border to the smart area manager <b>140</b>. In step <b>870</b>, the administrator <b>160</b> determines whether the path is completed. If the path is not complete, the administrator <b>160</b> keeps moving until the path is complete. If the path is completed, the administrator <b>160</b> sends a request to the smart area manger <b>140</b> to close the smart area being defined (step <b>880</b>). In step <b>890</b>, the smart area is defined by the smart area manager <b>140</b>. For example, the smart area manager <b>140</b> defines the smart area by computing the closest geometric figure substantially resembling the path. For example, a border of the smart area is determined based on the geometric figure, such that electronic services may be provided to a user crossing the border and entering the smart area. In step <b>895</b>, one or more policies are linked to the defined smart area. Some or all of the steps in the method <b>800</b> may be repeated for defining multiple smart areas. For example, steps <b>830</b>-<b>895</b> may be repeated for each smart area being defined.

P-0048[0048] FIGS. <b>9</b>A-D illustrate defining smart areas according to another embodiment of the invention. FIG. 9A illustrates static nodes <b>110</b><i>a . . . e </i>placed, for example, by the administrator <b>160</b>. The static nodes <b>110</b><i>a . . . e </i>may communicate with each other to determine a coordinate system and provide location information within the coordinate system for each of the static nodes <b>110</b><i>a . . . e </i>to the smart area manager <b>140</b>. The administrator <b>160</b> uses the trusted mobile node <b>170</b> to communicate with the smart area manager <b>140</b>.

P-0049[0049] As shown in FIG. 9B, the administrator <b>160</b> moves to a location <b>910</b>, substantially in a center of the smart area being defined. At the location <b>910</b>, the administrator <b>160</b> transmits location information to the smart area manager <b>140</b>. In FIG. 9C, the administrator <b>160</b> moves a distance <b>930</b> from the location <b>910</b>. The distance <b>930</b> may include a distance from the location <b>910</b> to a location <b>920</b>, which may be a location on the border being defined. The geometric figure is selected, and the border of the smart are being defined is determined based on the selected geometric figure and the distance. For example, the geometric figure selected is a circle. The area of the circle is calculated based on the distance <b>930</b>, and the border of the smart area <b>105</b> being defined is the border of the circle, whereby the center of the circle is the location <b>910</b>. Other geometric figures may be selected. For example, a square may be used similarly to a circle. A rectangle may be used and the administrator may define two distances related to a length and a width of the rectangle for defining the border of a smart area.

P-0050[0050]FIG. 10 illustrates a method <b>1000</b> for defining smart areas, according to the embodiment of the invention shown in FIGS. <b>8</b>A-D. In step <b>1010</b>, static nodes (e.g., the static nodes <b>110</b><i>a . . . e</i>) are placed. In step <b>1020</b>, location information is determined for each static node.

P-0051[0051] In step <b>1030</b>, the administrator <b>160</b> moves to a location substantially at a center of the smart area being defined with the trusted mobile node <b>170</b> of FIG. 1. In step <b>1040</b>, location information is determined for that location substantially at the center of the smart area being defined. For example, the trusted mobile node <b>170</b> obtains its location information from static nodes. In step <b>1050</b>, the location information is transmitted to the smart area manager <b>140</b>.

P-0052[0052] In step <b>1060</b>, the administrator <b>160</b> selects at least one distance from the location substantially at the center. For example, the administrator <b>160</b> moves to another location. This location may be on a border of the smart area being defined. The administrator <b>160</b> determines location information for this location using the trusted mobile node <b>170</b> and transmits the location information to the smart area manager <b>140</b>. The distance is from the location substantially at the center of the smart area being defined to the location on a border of a smart area being defined.

P-0053[0053] In step <b>1070</b>, the administrator <b>160</b> selects a geometric figure, for example, using the interface <b>145</b> of FIG. 1. In step <b>1080</b>, an area of the geometric figure is calculated using the distance. In step <b>1090</b>, the smart area is defined based on the geometric figure. For example, the geometric figure substantially becomes the smart area. Thus, the area of the geometric figure is the area of the smart area, and the center of the geometric figure is the center of the smart area, such as determined at step <b>1040</b>. Also, the border of the geometric figure is the border of the smart area. In step <b>1095</b>, one or more policies are linked to the defined smart area.

P-0054[0054] In step <b>1060</b> more than one distance may be selected if more than one distance is needed to calculate the area of the selected geometric figure. Also, certain steps of the method <b>1000</b> may be performed in an order different than described above. For example, the geometric figure may be selected before determining the distance. Also, some or all of the steps in the method <b>1000</b> may be repeated for defining multiple smart areas. For example, steps <b>1030</b>-<b>1095</b> may be repeated for each smart area being defined.

P-0055[0055] While this invention has been described in conjunction with the specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. There are changes that may be made without departing from the spirit and scope of the invention.
