FIELD 
     The present invention relates to a method for linking Internet-based forums and weblogs to a Push-to-Talk (PoC) platform. 
     BACKGROUND 
     In today&#39;s Internet world, the number of weblogs is rapidly increasing. A weblog, often simply called “blog”, is a website that periodically receives new entries. New entries appear at the top, older ones follow in reverse chronological order. Communities surface, assist each other in the Internet world, and use text messages, pictures, etc., in guestbooks and forums. It is therefore desirable to make these forums and weblogs accessible to the mobile world as well. 
     It is the object of the invention to present a method and a system for linking Internet-based forums and weblogs to a mobile communication system. 
     This object is met according to the invention with the characteristics of the independent claims, with reference being made here to the contents of the independent claims. 
     Preferred embodiments of the invention are defined in the dependent claims, with reference being made here to the contents of the dependent claims. 
     The inventive method for linking Internet-based forums and weblogs to a Push-to-Talk platform of a mobile communication system is characterized in that a novel PoC log storage platform and a novel interface to the existing Push-to-Talk platform is included. The Push-to-Talk platform communicates with the novel PoC log storage platform via the interface. The PoC log storage platform stores media data that was transmitted from the user equipment via the Push-to-Talk platform and makes it accessible to the Internet and to other mobile subscribers. Similarly as in web forums and weblogs, the media data is made accessible to the end user. In addition to that, the user equipment can itself also retrieve this data again via the Push-to-Talk platform. A novel client, for example in the form of a lean http client, is provided on the user equipment for this purpose. 
     Today&#39;s Internet-based web forums and weblogs are enjoying increasing popularity. This invention presents a way to utilize the Push-to-Talk system as a transport system to ensure a simple mobile link to web forums and weblogs. Additionally, not only text-based contributions, but voice/video contributions can be written and transmitted as well. 
     The PoC platform thus serves as an enabler service, i.e., use is made of PoC as an enabler for “PoC logs.” 
     SUMMARY 
     The invention relates to methods for offering weblogs in the mobile field with the aid of Push-to-Talk as an enabler system. The methods contain the following services improvements:
         Introduction of a novel intelligent guest-book-compatible and forum-compatible PoC log storage platform for Push-to-Talk for different types of media.   Introduction of novel interfaces on the PoC platform, to forward PoC messages to the PoC log storage platform.   Introduction of novel interface capabilities between user equipment and PoC server, to query and retrieve log information (nicknames, titles, MSISDNs) from the user equipment.   Introduction of novel interface capabilities between PoC server and Internet/third parties, to create guestbooks and/or forums, and to monitor, control and manage them.       

     Service Aspects
         The mobile radio network operator who operates (hosts) a platform also offers PoC logs for his own purposes, as well as for third parties and end users.   The mobile radio network operator offers channels for third parties and end users to create and offer mobile-radio-specific logs of various media types.   The mobile radio network operator develops a platform for creating/offering, storing, querying and recovering logs that carry different types of media.   The mobile radio network operator offers PoC logs; the mobile radio network operator offers a PoC log interface to third parties; the mobile radio network operator offers PoC logs for direct Internet customers.       

     Business Opportunities for Mobile Radio Network Operators 
     The mobile radio network operator who operates (hosts) the platform, achieves the following benefits:
         User friendliness of PoC (not only written logs, but voice logs are possible as well, simply by depressing a button) for mobile people.   A simple charging model by using an existing PoC charging model for end users, no additional fees for using the mobile radio network operator logs (integrated pricing), possibly additional fees for creating third-party logs and creating subscriber logs.   The number of communities on the Internet continues to grow, the use of weblogs continues to grow at a high rate, so why not utilize the potential for the mobile radio business.   The mobile radio network operator has, and supplies the PoC customer basis (attractive for third parties who offer mobile-radio-specific logs).   The mobile radio network operator supplies PoC infrastructure, additional investment only with respect to novel PoC log storage platform.   The mobile radio network operator can monitor, manage and control communication behavior, including that of third-party customer bases.   Circuit-switched (CS) and packet-switched (PS; if applicable) mobile-radio telephone calls/traffic may increase in the case that PoC logs offer the possibility to easily deposit MSISDNs, mail addresses, PoC addresses, etc., in the logs.   PS calls can easily be combined with general PoC infrastructure by using IMS (multiplier for introducing IMS).   People who did not know about it before and became aware of it through the use of POC logs, can initiate CS/PS calls to each other; potential for revenue growth, potential for increased ARPU, since communities help each other through phone calls.   Generating an increase in the mobile radio traffic, due to a participation and interaction of the communities of the fixed Internet world.   Uncoupling of communities who use the same PoC user equipment. This makes it possible to reach a broader spectrum of users due to the fact that PoC users can use PoC user equipment to communicate with a forum of users who do not necessarily need to have their own PoC-compatible, i.e., PoC-capable handset.       

     Technical Effect
         Creation of a PoC log storage platform for creating, offering, storing, querying and recovering PoC logs.   Creation of a PoC protocol from the user equipment to the PoC log storage platform, to retrieve log information (content, names, MSISDNs, nicknames, time stamps, moods, etc.)

     DETAILED DESCRIPTION 
       FIG. 1  shows the characterization and structure of PoC logs. Each log  10  has a unique identifier, for example in the form of a Log ID. The identifier is generated when the PoC log is created. The identifier may contain log-specific and provider-specific information. Each contribution  11 ,  12  to a PoC log  10  has a unique sub-identifier, Sub Log ID, and may contain information about the supplier of the message, (e.g., MSISDN, e-mail, PoC-group addresses, etc.) The PoC log  10  may contain different types of media (voice, text, images . . . ), depending on the user equipment settings and on the options that are available to the supplier of the message. 
     The general architecture is shown in  FIG. 2 . User equipment  20  is given access, in a known manner, via available access networks, such as GPRS  21 , WLAN  22 , fixed network  23 , to an IP multimedia subsystem (IMS)  24 . The IMS  24  is responsible for authenticating the user equipment  20 , for the session control, for the routing, as well as for the quality control (QoS) and subscription verification. The access networks  21 ,  22 ,  23 , are additionally connected to a Push-to-Talk over Cellular (PoC) platform  25 , which makes corresponding PoC services available to the users and which performs a user authorization for the PoC services. The IMS  24  is connected via an SIP/ISC interface to the PoC platform  25 . 
     The architecture of the service is characterized by a novel PoC log storage platform  26 , which is connected via an interface to the PoC platform  25 . Via this interface, log media are transmitted between the PoC log storage platform  26  and the PoC platform  25 . The PoC log storage platform  26  additionally offers interfaces  27 ,  28 ,  29  for the administration, creation and deletion of logs. The interfaces  27 ,  28 ,  29  could be used by the mobile radio network operator through third-party administrators or even by subscribers. All user types can create new logs and delete and administer them. The logs contain subscriber-specific information and access rights for the subscriber and a reference to the logs. The PoC log storage platform  26  additionally contains a so-called lean front end  30  for the user equipment  20 , to retrieve logs, log information, and the ability to select a log or media from logs via the user equipment. The PoC client that is implemented on the user equipment is therefore able to interact with a log lean HTTP client  31 , which is likewise provided on the user equipment. The user equipment  20  is therefore also slightly impacted when it supports the PoC log service. 
     Example Applications 
     All of the example applications will be based on the assumption that logs on the PoC log storage platform  26  were previously created with the aid of the user interfaces  27 ,  28 ,  29  by the mobile radio network operator, by the third parties, or by the end users, with the aid of well-known protocol mechanisms, such as http (user name and password). The most important novel service scenarios can therefore be characterized by the sending of log contributions via PoC, recovering of the of log information via PoC and querying log information and query logs (search logs and sublogs before logs are sent/recovered). 
       FIG. 3  shows the sending of a contribution to logs with the use of PoC and IMS. In the first step, an IMS and PoC registration of the user equipment  20  takes place with the IMS  24  and with the PoC platform  25 . In the second step, a retrieving of PoC logs IDs takes place in the PoC log storage platform  26  by searching areas of interest. In a third step, the user is able to register with the aid of his user equipment  20  with the PoC platform  25 , with a specific, pre-determined PoC group for PoC logs. In a fourth and fifth step, PoC media can be sent from the user equipment by means of data bursts to the PoC log storage platform  26  and to the log, identified by the Log ID. The media are stored in the log and a Sub Log ID is generated for the corresponding contribution. The stored medium can now be retrieved under the Sub Log ID by all front ends, both mobile and fixed. 
       FIG. 4  shows a process of retrieving contributions from logs with the use of PoC and IMS. In the first step, an IMS and PoC registration of the user equipment  20  takes place with the IMS  24  and with the PoC platform  25 . In the second step, a retrieving of PoC logs IDs takes place in the PoC log storage platform  26  by searching areas of interest. In a third step, the user is able to register with the aid of his user equipment  20  with the PoC platform  25 , with a specific, pre-determined PoC group for PoC logs. In a fourth step, the user can initiate a query of a log via the Log Sub ID by depressing a PoC button on his user equipment  20 . This message is transmitted in a fifth step from the PoC platform  25  to the PoC log storage platform  26 . At the PoC log storage platform  26 , information belonging to the Log Sub ID, e.g., contributions and media, are then retrieved and transmitted in the sixth step to the PoC platform  25 . In a seventh step, a transmission of the information then takes place via a PoC channel from the PoC platform  25  to the user equipment  20 . The user equipment  20  makes intelligent means available for calling up the media. 
       FIG. 5  shows a process of retrieving a log by searching areas of interest. In a first step, an IMS and PoC registration of the user equipment  20  takes place with the IMS  24  and with the PoC platform  25 . In the second step, a direct retrieving of PoC logs IDs takes place in the PoC log storage platform  26  by searching of areas of interest. The user equipment  20  makes intelligent means available for this purpose for calling up the media. 
     Prospects 
     The PoC log storage platform  26  provides the possibility to create, send, retrieve and query log information. In the future, it could additionally also be possible to take the user address from the log-ID information and immediately start a call via IMS to the log participant. With this type of service, the services-interaction scenarios could grow quickly, and IMS will be the solution in the mobile radio network.
