The pictograms can featured content represent and trigger the display of the content if they are pressed. additionally can pictograms are provided to the user the option to request, Consideration to give to ignore and to store content, such as this in more detail below explained is.

As mentioned this was the mobile terminal <figref>10</figref> so configured to specific content or the availability of content to the wireless communication network cells <figref>12</figref> assigns. Preferably leads the control Panel <figref>46</figref> the mobile terminal <figref>10</figref> a table for a Number of cells and associated Content indexes. The content indexes can simply be a flag, the availability, the of content and an address for the displaying content, or they can of actual Content made.

On on the Control Panel <figref>46</figref> process running, the here hereinafter referred to as device-resident program (DRP) is referred to, can be configured so that it has a performs access to other processes, on the Control Panel <figref>46</figref> proceed to the cell to identify, currently the mobile terminal <figref>10</figref> with services provided. The DRP may continue to identify changes in the supply cells. Dependent on on the configuration, the DRP is a service-providing Cell or a change the service-providing cells identify and then the Use table to determine if the cell content associated is. In particular, the DRP may be a cell using identifications for the the service-providing base station <figref>14</figref> or similar identify.

at one embodiment of the present invention are cells generally known localities assigned and are used for their definition. By defining of localities can by cells User and content provider identify more effectively generally designated locations or assign without having an understanding of the Cell Design have and ID.

&lt;?page 7?&gt;

The Cells and available Content that assigns table can be based on the position of the mobile terminal <figref>10</figref> updated are, in order to avoid that the mobile terminal <figref>10</figref> all available cells Track and notice must indicate whether content is available for the cells. The number of cells or locations, which are shown in the table, depending of the available Memory and the desired Change processing speed. For the The purpose of describing the cells and available content that assigns table as Örtlichkeits table designated. An example of a process, of which the operation control Panel <figref>46</figref> in connection with the DRP, or its control outlines, is in the <figref idrefs="S26">4A</figref> and <figref idrefs="S27">4B</figref> shown.

will initially a Örtlichkeits table to the mobile terminal <figref>10</figref> downloaded (Step <figref>100</figref>), Wherein the system controller <figref>46</figref> among the control of the DRP processes Control <figref>46</figref> monitors, identifying the services-providing or serving cell (Step <figref>102</figref>). The DRP performs monitoring for a change the serving cell (step <figref>104</figref>). If there is no Cell change are monitored the DRP continue the serving cell (step <figref>102</figref>).

If there is a change the serving cell are (step <figref>104</figref>), Then the new Cell identifies (step <figref>106</figref>) And the Örtlichkeits table is searched to determine whether the new serving cell appears in the table (step <figref>108</figref>). If no match is found (step <figref>110</figref>), So called on the Control Panel an update for the Örtlichkeits table at, typically from the application server <figref>18</figref> (Step <figref>112</figref>). The update is received (step <figref>114</figref>), and the DRP updates the Örtlichkeits table (Step <figref>116</figref>).

Among Assuming that a match initially or is found after an upgrade (step <figref>110</figref>) determines the DRP whether content for the cell available (step <figref>118</figref>). In one embodiment, the determination, whether content available is met by allowing for a position in the table for the Serving cell is and determines whether the associated content is available. The indicator the availability the content may be simply the presence of a flag. Alternatively, the table selected Content or an address for Include the content.

If the table indicates that no content is available for the serving cell (Step <figref>120</figref>), The DRP starts monitoring a change in the Cells and repeats the above process again. If content available (step <figref>120</figref>), Can determine the DRP that Content actually the Application server <figref>18</figref> is available (step <figref>122</figref>). Although Örtlichkeits table may indicate that content available is, itself, the actual availability the contents have changed since the update of Örtlichkeits table or there may be problems on the network, to access prevent the content.

Thus can be a request to the application server <figref>18</figref> sent are to ensure the availability to examine the contents (Step <figref>122</figref>). In response, the mobile terminal receives<figref>10</figref> a Display that content available (step <figref>124</figref>), And the DRP can the user of the mobile terminal <figref>10</figref> correspondingly by providing audio or visual indices to the user point this (step <figref>126</figref>). In response, the user can an indication supply, whether the content should be delivered to the user or (step <figref>128</figref>).

If the user elects to receive the content (step <figref>130</figref>) returns the DRP for monitoring to a change the serving cell back. If the user decides to receive the content (step <figref>130</figref>) controls the DRP, the system controller such that this actual content via the Application server <figref>18</figref> or from the content server <figref>22</figref> directly requesting (step <figref>132</figref>). In response receives the mobile terminal <figref>10</figref> the Content (step <figref>134</figref>), And the DRP, the system controller <figref>46</figref> at, to deliver the content to the user in a specified way (Step <figref>136</figref>). Upon receipt of the content, the user can Just look at the information and discard, or the information may include additional Links include whereby an iterative process of requesting and receiving additional Information to the user's request and under guidance by the Content is started.

On Overall communication flow diagram for an embodiment of the present invention is in <figref idrefs="S28">5</figref> shown. When a mobile terminal<figref>10</figref> a requesting content or availability content checks so is a content request initiated. The content request is preferably a request the hypertext transfer protocol (HTTP), and it is intended to the application server <figref>18</figref> directed to be to the execution a content-Zustellungs Service initiate (step <figref>200</figref>). As previously mentioned above, , the application server <figref>18</figref>When configured to is, some sent together with the content request information, such as identification indices of the mobile terminal <figref>10</figref> and the serving cell, use, and a request for additional Position information to the mobile position determination server <figref>24</figref> send (step <figref>202</figref>).

Of the Mobile position determination server <figref>24</figref> provides some Kind of Positionsbestimmungssys&lt;?page 8?&gt;system or service is, the wireless the Communications network <figref>12</figref> or other position determination systems is associated with, which in the Capable of providing a location of the mobile terminal <figref>10</figref> to identify. Preferably, the position information is used for fine adjustment of the Position of the mobile terminal <figref>10</figref> or for determining the position of the mobile terminal <figref>10</figref> within a predetermined cell used in other ways. The position request is preferably a message in an extended marking language (XML), but is the expert recognize that the message can take many other forms.

As Response to the positioning request delivers the mobile location determination server <figref>24</figref> additional Position information to the application server <figref>18</figref> (Step <figref>204</figref>). The application server <figref>18</figref> uses the serving cell and the additional Position information, if available, for the Access to a profile in the profile database <figref>20</figref>, to realize, whether content based on the position and / or the identified mobile terminal <figref>10</figref> is available (Step <figref>206</figref>). The application server<figref>18</figref> receives the Profile Info (Step <figref>208</figref>) And calls any available content from the content server <figref>22</figref> (step <figref>210</figref>). Among Assuming that content available is provided by the content server <figref>22</figref> the requested content to the application server <figref>18</figref> (Step <figref>212</figref>), The information to the mobile terminal <figref>10</figref> send can, indicating that content is available (step <figref>214</figref>). In response asks the mobile terminal <figref>10</figref> the user of the mobile terminal <figref>10</figref>. to determine whether he wants to receive the content directly (A), the content of later wants to store viewing (B), want to ignore or content (C). The mobile terminal<figref>10</figref> becomes Therefore, information regarding the the user response to the application server <figref>18</figref> send (Step <figref>216</figref>), Which responds accordingly.

If selected users had to directly receive the content (A), thus providing the application server <figref>18</figref> the Content to the mobile terminal <figref>10</figref> (Step <figref>218</figref>). The mobile terminal <figref>10</figref> confirmed preferably the reception of the content by sending a corresponding acknowledgment (ACK) to the application server <figref>18</figref> (Step <figref>220</figref>).

If the user would have decided, the content of later recovery to store (B), then the application server <figref>18</figref> the content to the online spare database <figref>26</figref> provide for storage (Step <figref>222</figref>). Preferably, the online backup database responds<figref>26</figref> With a confirmation to the application server <figref>18</figref> (Step <figref>224</figref>). Of the Application server <figref>18</figref> may then receive a confirmation of Reserve storage to the mobile terminal <figref>10</figref> for future reference send (step <figref>226</figref>).

If the user has decided to ignore the content (C), so true the application server <figref>18</figref> no further action on the confirmation the reception of the response to the mobile terminal <figref>10</figref> addition (step <figref>228</figref>).

Of the Skilled in the art the scope and flexibility of the present invention recognize. The inventive concepts enable effective tracking of mobile devices <figref>10</figref>To selected position specific Content to mobile devices <figref>10</figref> to supply. The delivery of the content, by one or more Profiles can be controlled, or from the user of the mobile terminal are constructed from information providers. To determine whether content available is, can multiple profiles checked be to ensure that the user actually selected information wishes. For example, an information provider diverse types of information for a predetermined position available have while A user profile can be used to filter the information , in order to provide only the information that is available and desired by the user is.

Of the Application server <figref>18</figref> may support services in where users and information providers profiles based Defining of locations can, wherein locations Cells or positions are assigned in the background. Thus, an information service provider or a user want it, to provide information or receive, when a user located in Chinatown, Little Italy or at The Waterfront, everything within a selected City. In these cases based locations to positions in the real world and areas, and the system architecture can determine which cells, groups of cells, sectors within of cells or the like corresponding to these areas.

Of the Content, the mobile to the terminal <figref>10</figref> supplied or is delivered, can advertising, traffic information, weather information, Maps, directions, historical information or the like for a Include user, if they are located at a position at which the information is important.

In fact, a mobile terminal <figref>10</figref> a relatively manageable list of cells for a particular location Download and compare their present position to the list. If the present position seems to contain information that can mobile terminal <figref>10</figref> the Application server <figref>18</figref> about a short message service (SMS), over a wireless Anwendungsprotokoll- &lt;?page 9?&gt;(WAP -) / HTTP browser or other in-band communication function query to this to provide information. Alternatively, the user may be notified be that content available is, and it can determine whether to receive the information or not.

Typically closes the mobile terminal <figref>10</figref> a Box that defines multiple contiguous areas, wherein the mobile terminal <figref>10</figref> the notes change from one area to another and the user information or indicating that such information is available. If For example, an overall table on a place, a city or zip code refers, as cell arrays can within Table Companies areas, shopping areas and tourist areas represent. The tables can are updated when the mobile terminal <figref>10</figref> from a coverage area is moved out.

The defined by the cell areas can be divided into smaller areas be when additional Position information available is. Furthermore, the triggering event to determine whether content available is, many forms in addition to a simple trigger have when entering a new area, such as when a serving cell is changed. The mobile terminal<figref>10</figref> can be configured so that it periodically searches for information, while it is within a predetermined cell or area definition. The skilled artisan will diverse Techniques to provide additional tripping characteristics and recognize the control of content, delivered online within Teachings are.

Of the Skilled in the art will recognize that improvements and modifications to Preferred embodiments of the present invention can be made without from the scope of the claims departing.
