     FIELD OF THE INVENTION 
     The present invention relates to a method of and an apparatus for controlling broadband access and distribution of content and communications through an access point. In particular, the present invention relates to a method of and apparatus for controlling the quality of content provided over a broadband infrastructure through an access point to a plurality of end user network devices. 
     BACKGROUND OF THE INVENTION 
     Current broadband transmission occurs from broadband infrastructure providers to end users via such infrastructure as telephone DSL, TV cable, satellite, etc. Broadband content, such as movies, music, TV shows, web access, etc., that is transmitted over the broadband transmission infrastructure is provided by content providers. Some broadband infrastructure providers determine which content providers can provide content over their networks. For example, a cable television service provider determines which channels, such as HBO, ESPN, or CNN, are available to their end user customers. 
     Current state of the art of QoS (Quality of Service) is available for the broadband transmission infrastructure, that is the physical infrastructure from the broadband infrastructure service provider location to end user premise located broadband network devices, such as a DSL/cable termination, DSL/cable modem, wireless/wired router, or general access point. The QoS is applied to the physical transmission medium, and as such, the quality of all content provided over any given physical medium is dependent on the QoS of that given physical medium. All content provided over the given physical medium is subject to the same QoS. 
     However, the broadband infrastructure provider has no control over the actual content that is provided by the content providers. The broadband infrastructure provider may wish to manage, or even block, certain content within the content provided by the content provider, but is unable to modify the content provided. A QoS is not available for broadband “content”, especially from the end user broadband network device to an end user device such as a computer, TV, or telephone. In other words, current QoS methodologies enable broadband transmission infrastructures with required quality levels, but do not provide selective control of the “content” that is transmitted over these same infrastructures. 
     SUMMARY OF THE INVENTION 
     The present invention generally describes a method of and a system for broadband/infrastructure providers to set, control, and operate a coercive/disruptive controller (CDC) to manage and provide broadband content to an end user device. 
     Embodiments of the present invention are directed to a controller that controls broadband content and communication from an end user broadband network access device to an end user device. Examples of an end user broadband network access device include, but are not limited to, a DSL modem, a cable modem, a DSL termination, a cable termination, a wireless router, or a wired router. In general, the end user broadband network device is an access point to the broadband infrastructure. Examples of an end user device include, but are not limited to, a computer, a network appliance, a television, a telephone, a personal digital assistant (PDA), or any device capable of receiving broadband content. Communication between the access point and the end user device preferably includes a broadband connection, either wired or wireless. Wireless transmissions can be made over public standard based IEEE 802.11 a/b/g, Wi-Max, or any other wireless based transmission media. Wired transmissions can be made over local area network (LAN), wide area network (WAN), or any other wired transmission media. 
     In one embodiment, the controller is integrated within the access point and utilizes content parameters and operation logic to manage and control broadband content transmitted to the end user devices. In another embodiment, the controller is a stand alone device coupled to the access point within a home or enterprise network. The controller either operates independently or is dynamically set and controlled by a remotely coupled external controller or server. Using the controller, broadband content and communication for end user devices is seamlessly, dynamically, concurrently, and coercively/disruptively controlled. 
     The access point and the controller of the present invention preferably enable broadband/infrastructure providers to dynamically manage and administer the broadband content provided to the end user devices. For example, through the use of a local controller and/or an externally coupled coercive/disruptive controller, QoS content parameters are set/reset, assigned/reassigned for broadband content provided by any given content provider. QoS parameters define, for example, jitter, priority, level of filtering, etc. Broadband content is managed and administered according to the QoS content parameters, where the QoS content parameters are content specific, that is based on content origination, specific content, and/or specific content characteristics. As such, the QoS content parameters are adjusted based on the broadband content, making the QoS related to the broadband content independent of the content quality provided by the content provider. In this manner, the access point provides a content-specific QoS, where the QoS is applied to the actual content, not to the physical media that delivers the content. 
     Additionally, the access point monitors and collects usage statistics associated with all content accessed by the end user devices through the access point. One or more external control servers collect the usage statistics from each access point, thereby compiling macro-level statistics related to content accessed by end user devices. The one or more external control servers can be co-located with the network equipment of the broadband infrastructure provider, or the one or more external control servers can be independent of the broadband infrastructure.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  illustrates an exemplary block diagram of one or more end user devices  100 - 104  coupled to an access point  120  of the present invention. A broadband content controller  122  is preferably integrated within the access point  120 . Alternatively, the broadband content controller is implemented as a stand alone end user network element, wireless or wired, which is configured within a home or enterprise network associated with the end user devices. In this alternative embodiment, the broadband content controller is coupled to a conventional end user broadband network access device to manage the content provided to the end user devices, as will be explained in greater detail below. 
     The access point  120  also includes a transceiver  128  adapted to transmit signals to and receive signals from network connections  106 ,  108 ,  110 , and  132 . Each of the network connections  106 ,  108 ,  110 , and  132  can be either a wireless connection or a wired connection. As such, the transceiver  128  is configured for both wired and wireless network communications. 
     Each of the end user devices can be configured for wireless, wired, or both wireless and wired communications. Exemplary end user devices include, but are not limited to, computers, televisions, music players/recorders, PDAs, telephones, or any conventional end user device capable of receiving broadband content. The end user device can also be a mobile communication device configured to automatically switch an existing communication from a cellular network to a wireless IP network, or to switch an existing communication from an IP network to a cellular network. Such a mobile communication device is described in co-pending and co-owned U.S. patent application Ser. No. 11/031,498, filed Jan. 6, 2005, and entitled “TELEPHONE WITH AUTOMATIC SWITCHING BETWEEN CELLULAR AND VOIP NETWORKS”, which is hereby incorporated by reference. 
     As shown in  FIG. 1 , the end user device  100  is a wireless device coupled to the access point  120  via the wireless connection  106 . Similarly, the end user device  102  is a wireless device coupled to the access point  120  via the wireless connection  108 . The end user device  104  is a wired device coupled to the access point  120  via the wired connection  110 . It is understood that the specific types of end user devices  100 ,  102 , and  104 , and the specific transmission connections  106 - 110  made between the end user devices  100 - 104  and the access point  120  described above in relation to  FIG. 1  are for exemplary purposes only. 
     When the connection between an end user device, such as the end user device  104 , and the access point  120 , is a wired connection, such as the wired connection  110 , the end user device  104  preferably functions as a network access terminal extension, for example a telephone cradle. 
     The access point  120  is coupled to a broadband termination block  130  via the broadband connection  132 . The broadband connection  132  can be a wired connection or a wireless connection. A wired connection to access point  120  can be configured according to any conventional wired transmission protocol including, but not limited to, those used in LANs and WANs. A wireless connection to the access point  120  can be configured according to any conventional wireless transmission protocol including, but not limited to, IEEE 802.11 a/b/g and Wi-Max. 
     The broadband termination block  130  is either a physical device or a logical node where broadband content is received from an external source, such as a broadband infrastructure provider, and then supplied to the access point  120 . The broadband content includes content data, such as audio content data and/or video content data, as well as content header data that provides information related to the accompanying audio/video content data. Examples of content header data include content origination address, content specific information, video parameters, audio parameters, and transmission media-specific parameters. The broadband content is provided from the broadband termination  130  to the access point  120 . As the broadband termination block  130  can be considered a logical node, in an alternative embodiment, the broadband termination block  130  is included within the access point  120 . 
     The broadband content controller  122  sets quality of service (QoS) transmission characteristics associated with transmission of the received broadband content to the end user devices  100 - 104 . The QoS transmission characteristics can differ or be the same depending on whether the connection between the access point  120  and the end user devices  100 - 104  are wired or wireless. The transmission characteristics are also determined by the broadband content origination and by the nature of the audio/video content data. A content parameters module  124  maintains various content parameter values associated with the QoS transmission characteristics. These content parameter values are sent by the broadband content controller  122  to the content parameter module  124 , or stored content parameter values are sent by the content parameter module  124  to the broadband content controller  122 . Preferably, the content parameter values maintained by the content parameter module  124  are dynamically set by the broadband content controller  122 . The content parameter values are used by the controller  122  to manage the content provided to the end user device  100 - 104 . Content received by the access point  120  from the broadband termination block  130  is monitored for its source. That is, each content is associated with a specific content provider. A QoS is associated with each content provider so that content parameter values associated with each content provider are set according to the QoS of that content provider. 
     In operation, the broadband content controller  122  controls the transmission of broadband content and communications to the end user devices  100 - 104 . The controller  122  is preferably integrated within the access point  120 . Alternatively, the controller  122  is included within a stand-alone network device coupled to an end user broadband network element, where the stand alone network device and the end user broadband network element are included within a home or enterprise network. The controller  122  monitors broadband content received from the broadband termination block  130  to determine a content source of the broadband content. Using the determined content source, the controller  122  retrieves content parameter values from the content parameters module  124 , where the retrieved content parameter values are associated with the determined content source. The retrieved content parameter values dictate the QoS transmission characteristics to be executed by the controller, as applied to the received broadband content. The QoS transmission characteristics can include, but are not limited to, a processing rate, a priority level, or a degree of filtering. Where the access point  120  receives more than one data stream of broadband content, the priority level indicates which data stream is processed first, which is processed second, and so on. The access point  120  can also include various processors with different processing speeds, where the content parameter values can dictate which processor is to be used. The access point  120  can also include one or more filter types, where the content parameter values can dictate whether or not the broadband content is filtered for noise, what quality filter is used, or whether or not the broadband content is blocked entirely. 
     Using the content parameter values to implement the QoS transmission characteristics for a given content provider, the controller processes the received broadband content before the content is sent to one or more of the end user devices  100 - 104 . In this manner, the actual content is managed prior to delivery to the end user device. 
     Preferably, each access point  120  is also configured to collect usage statistics associated with all content that is accessed by the end user devices  100 - 104 . The usage statistics represent information related to the content transmitted to the end user devices  100 - 104 , and as such, the usage statistics represent the content usage patterns of the users of the end user devices  100 - 104 . The usage statistics are stored in a database  126 . 
       FIG. 2  illustrates an exemplary block diagram of a system including multiple access points  120  and an external control server  242 . Preferably, the control server  242  is co-located at a central office of a broadband infrastructure provider  240 . Alternatively, the control server  242  is implemented as a stand alone end user network element coupled to each of the access points  120 . Although the system is shown in  FIG. 2  as each access point  120  coupled directly to the control server  242 , alternative embodiments are contemplated in which an access point is indirectly coupled to the control server via one or more intermediate access points. The network connections  232  are configured using any conventional communications media, either wireless or wired. The network connections  232  can be either the same network connections, such as the network connection  232 , used to transmit broadband content from the broadband infrastructure provider  240  to the access points  120 , or the network connections  232  can be independent of the network connections used to transmit broadband content from the broadband infrastructure provider  240  to the access points  120 . 
     In the preferred embodiment, the control server  242  provides control commands and instructions to the controller  122  ( FIG. 1 ) within each access point  120 . In part, these control commands and instructions set, reset, assign, and reassign the QoS transmission characteristics associated with transmission of the broadband content from the access point  120  to the end user devices  100 - 104  ( FIG. 1 ). The control server  242  maintains control of the content parameter values, which dictate the QoS transmission characteristics, stored in the content parameters module  124  ( FIG. 1 ) of each access point  120 . The access point  120  then processes the broadband content according to the stored content parameter values, as described above in relation to  FIG. 1 . The access point  120  administers the control commands and instructions sent from the control server  242  by dynamically managing and processing the broadband content before it is transmitted to the end user devices  100 - 104  ( FIG. 1 ). 
     The control server  242  also functions as a centralized collection system that collects the usage statistics from each of the access points  120  in the system. The control server  242  maintains a database of the collected usage statistics that provides compiled usage information for all content distributed through the access points  120 . Although the control server  242  is shown in  FIG. 2  as a single server, the control server  242  can include more than one server networked together. In this case, the compiled usage statistics can be maintained in one of the servers, or the compiled usage statistics can be copied such that two or more of the networked servers maintain a copy of the compiled usage statistics. 
     In operation, the control server  242  preferably manages QoS transmission characteristics of the broadband content provided by the access points  120  to any end user device coupled to receive the broadband content. The access points  120  preferably process and then transmit the broadband content according to the QoS transmission characteristics provided by the control server  242 . The control server  242  also collects the usage statistics stored by each of the access points  120 . These usage statistics are compiled to form macro-level content usage patterns. 
       FIG. 3  illustrates an exemplary methodology for dynamically configuring broadband content transmitted to end user devices by an access point. At the step  400 , broadband content is provided to a broadband provider. At the step  410 , broadband content parameters are set and maintained within the access point. In one embodiment, management and administration of the broadband content parameters is controlled by an external control server. In another embodiment, a broadband content controller within the access point independently sets and defines the broadband content parameter values. At the step  420 , the broadband content is transmitted by the broadband provider to the access point. The access point is preferably an end user broadband network element, which can also function as a broadband termination point. 
     At the step  430 , the broadband content is dynamically configured within the access point, where the broadband content is configured according to the broadband content parameters. The broadband content parameters define content-specific QoS transmission characteristics which are to be applied on a content by content basis. At the step  440 , the configured broadband content is transmitted from the access point to one or more end user devices. The configured broadband content is transmitted to the end user devices over a wired or wireless connection. 
     At the step  450 , each access point collects usage statistics associated with the content transmitted through the access point to the end user devices. At the step  460 , an external control server collects and collates the usage statistics from each of the access points.
