BACKGROUND INFORMATION
With the advent of hardware and software capabilities of mobile phones and the increasing availability of residential broadband Internet service, customers are demanding services that operate seamlessly on both broadband and cellular networks. A typical broadband home network includes a router and one or more personal computers. The broadband home network may also include other types of network devices, such as set-top boxes, Network Attached Storage (NAS) devices, web cameras, etc. A typical router may implement Network Address Translation (NAT) and may include a built-in firewall and a Dynamic Host Configuration Protocol (DHCP) server. The router may connect to the Internet with a single dynamic public Internet Protocol (IP) address. Home network devices may use the router's DHCP assigned private addresses. Thus, the home network devices are typically not directly accessible from the Internet.

In one embodiment, for example, communication interface 640 may communicate with a network, such as network 140.
As will be described in detail below, customer remote device 130 may perform certain operations in response to processing logic 610 executing software instructions of an application contained in a computer-readable medium, such as memory 620. The software instructions may be read into memory 620 from another computer-readable medium or from another device via communication interface 640. The software instructions contained in memory 620 may cause processing logic 610 to perform processes that will be described later. Alternatively, hardwired circuitry may be used in place of or in combination with software instructions to implement processes described herein. Thus, embodiments described herein are not limited to any specific combination of hardware circuitry and software.
Although FIG. 6 shows exemplary components of customer remote device 130, in other embodiments, customer remote device 130 may include fewer, different, or additional components than depicted in FIG. 6. In still other embodiments, a component of customer remote device 130 may perform one or more of the tasks described as performed by another component of customer remote device 130.
FIG. 7 is a flow chart of an exemplary process, consistent with exemplary embodiments, for registering a user for remote access to the user's customer home network. In one embodiment, the processing of FIG. 7 may be performed by one or more components within service provider network 120. In another embodiment, some or all of the processing described below may be performed by another component or group of components including or excluding components within service provider network 120.
Processing may begin with service provider network 120 receiving user information from a user (block 710). For example, the user may use customer remote device 130 to connect to registration server 126. In one embodiment, the user may connect to registration server 126 using a web browser on customer remote device 130. Alternatively, customer remote device 130 may include an application that, upon execution, automatically establishes a connection to registration server 126. Upon connection to registration server 126, the user may provide, via customer remote device 130, user information to registration server 126. The user information may include, for example, a name, a home address, a mobile telephone number, etc. Alternatively, registration server 126 may determine this information automatically (e.g., by detecting a telephone number associated with customer remote device 130 (e.g., via automatic number identification) and using the detected telephone number to obtain information for the user from a database).
Service provider network 120 may create a user record for the user (block 720). For example, registration server 126 may use some or all of the information received from the user to create the user record in user database 122. In one embodiment, registration server 126 may create a new entry in user database 122 and store, for example, a telephone number associated with customer remote device 130 in user identification field 310.
Service provider network 120 may obtain an identifier for gateway device 114 associated with customer home network 110 (i.e. the user's customer home network) (block 730). For example, in one exemplary embodiment, registration server 126 may obtain the identifier for gateway device 114 from the user. In another exemplary embodiment, registration server 126 may obtain the identifier for gateway device 114 from a database that associates information relating to the user with the identifier (e.g., registration server 126 may look up the identifier for gateway device 114 using, for example, the user's name, address, and/or other information). Registration server 126 may store the obtained identifier for gateway device 114 in the new user record (e.g., in gateway identification field 320).
Service provider network 120 may request a snapshot of customer home network 110 from gateway device 114 using the identifier of gateway device 114 (block 740). For example, registration server 120 may transfer the obtained identifier for gateway device 114 to connectivity server 125/auto-configuration server 121. Reference to “connectivity server 125/auto-configuration server 121” may correspond to a connectivity server 125-auto-configuration server 121 interaction via a TR-069 Northbound Interface. Registration server 120 may subscribe with connectivity server 125 to receive notifications relating to the identifier for gateway device 114.
Connectivity server 125/auto-configuration server 121 may look up a network address (e.g., an IP address) for gateway device 114 using the identifier for gateway device 114 (e.g., from a database that associates the identifier of gateway device 114 with the network address for gateway device 114). Connectivity server 125/auto-configuration server 121 may send the request for a snapshot of customer home network 110 to gateway device 114 using the network address.
In response to receiving the request, gateway device 114 may obtain the snapshot of customer home network 110. In one exemplary embodiment, gateway device 114 may obtain the snapshot of customer home network 110 using the Universal Plug and Play discovery and description procedures. Other procedures for obtaining the snapshot of customer home network 110 may alternatively be used. The snapshot may include information regarding the type of each customer home device 112-1 through 112-N, an identifier for each customer home device 112-1 through 112-N, and/or one or more network addresses (e.g., an IP address, a MAC address, etc.) for each customer home device 112-1 through 112-N. The snapshot may also include, for each customer home device 112-1 through 112-N, vendor-specific information, such as the model name and number, serial number, manufacturer name, etc. The snapshot may further include, for each customer home device 112-1 through 112-N, a list of applications associated with the customer home device and information relating to the applications, such as an application name, an application identifier, an IP core protocol used by the application, a port number used by the application, a transport protocol used by the application, and/or additional information. Gateway device 114 may transmit the snapshot to service provider network 120.
Service provider network 120 may receive the snapshot of customer home network 110 from gateway device 114 (block 750). For example, connectivity server 125/auto-configuration server 121 may receive the snapshot from gateway device 114.
Service provider network 120 may store information from the received snapshot into a device table in user database 122 (block 760). For example, connectivity server 125/auto-configuration server 121 may transfer the received snapshot to registration server 126 based on registration server 126's subscription with connectivity server 125. Registration server 126 may store information from the received snapshot into the device table in device table field 330 in the newly created user record for the user. The stored information may include description information for each customer home device 112-1 through 112-N and a list of application identifiers for each customer home device 112-1 through 112-N.
Service provider network 120 may further create one or more application profiles in application database 123 for the applications residing on customer home devices 112 using information from the snapshot (block 770). For example, registration server 126 may create an application profile in application database 123 for each application residing on a customer home device 112-1 through 112-N. As illustrated in FIG. 4, each application profile may include an application name, an application identifier, an IP core protocol used by the application (e.g., TCP, UDP, etc.), the port number used by the application, the transport protocol used by the application (HTTP, FTP, etc.), and/or other information associated with the application (e.g., version number, an icon, the Universal Plug and Play service description for the application, etc.).
FIG. 8 is an example 800 of the interaction of components of service provider network 120 and customer home network 110 in the processing described above with respect to FIG. 7. As illustrated in FIG. 8, processing may begin with registration server 126 receiving user identity information from customer remote device 130 (act 810). In response, registration server 126 may create a user record in user database 123 (not shown) (act 820). Registration server 126 may further send a subscribe message to connectivity server 125/auto-configuration server 121 that includes an identifier for gateway device 114 (act 830). Connectivity server 125/auto-configuration server 121 may transfer a request (e.g., a TR-069-compliant request, referred to as a SetParameterAttribute method call in FIG. 8) to gateway device 114 for customer home device information (act 840). In response to receiving the request, gateway device 114 may perform Universal Plug and Play discovery and description procedures to obtain device description information and application (or service) description information. For example, gateway device 114 may interact with an application on customer device 112-1 to obtain device description information and application (or service) description information (act 850).
Gateway device 114 may transmit the device and application (or service) descriptions and the identifier for gateway device 114 to connectivity server 125/auto-configuration server 121 in a TR-069-compliant response (act 860). In response to receiving the information from gateway device 114, connectivity server 125/auto-configuration server 121 may send a notify message to registration server 126 that includes the device and application (or service) descriptions and the identifier for gateway device 114 (act 870). Registration server 126 may then update a device table in the newly created user record (act 880).
FIG. 9 is a flow chart of an exemplary process, consistent with exemplary embodiments, for updating a user's device table. In one embodiment, the processing of FIG. 9 may be performed by one or more components within service provider network 120. In another embodiment, some or all of the processing described below may be performed by another component or group of components including or excluding components within service provider network 120.
As indicated above, registration server 126 may subscribe to receive updates for the identifier of gateway device 114. Moreover, gateway device 114 may be configured to send status changes in customer home network 110 to connectivity server 125/auto-configuration server 121. Processing may begin with service provider network 120 receiving a change notification from gateway device 114 (block 910). For example, connectivity server 125/auto-configuration server 121 may receive the change notification from gateway device 114. The change notification may include a customer home device joining customer home network 110, a customer home device leaving customer home network 110, a customer home device being reconfigured, etc.
Service provider network 120 may update the appropriate device table in user database (block 920). For example, connectivity server 125/auto-configuration server 121 may transfer the change notification to registration server 126 based on registration server 126's subscription to receive notifications relating to the identifier associated with gateway device 114. In response to receiving the change notification, registration server 126 may update the appropriate device table in device table field 330 to reflect the information in the change notification. In this way, registration server 126 ensures that user database 122 stores the most recent information regarding customer home network 110.
FIG. 10 is a flow chart of an exemplary process, consistent with exemplary embodiments, for remotely interacting with an application in customer home network 110. In one embodiment, the processing of FIG. 10 may be performed by one or more components within service provider network 120. In another embodiment, some or all of the processing described below may be performed by another component or group of components including or excluding components within service provider network 120.
Processing may begin with service provider network 120 receiving a session initiation request from customer remote device 130 (block 1010). For example, a user of customer remote device 130 may initiate a session by sending a session initiation request to wireless application server 124. In one embodiment, the session initiation request may include a user identifier (e.g., a telephone number associated with customer remote device 130).
Service provider network 120 may obtain application identifier(s) for the user and an identifier for gateway device 114 from user database 122 (block 1020). For example, wireless application server 124 may use the user identifier received in the session initiation request to identify a user record from user database 122. Wireless application server 124 may obtain the gateway device identifier and application identifiers from gateway identifier field 320 and device table field 330 of the user record.
Service provider network 120 may retrieve application profile(s) from application database 123 (block 1030). For example, wireless application server 124 may use the application identifiers obtained from user database 122 to obtain the appropriate application profiles from application database 123.
Service provider network 120 may retrieve the public IP address for gateway device 114 (block 1040). For example, wireless application server 124 may send the identifier for gateway device 114 to connectivity server 125/auto-configuration server 121. Connectivity server 125/auto-configuration server 121 may use the identifier of gateway device 114 to look up a public IP address for gateway device 114 from a database that associates the gateway device identifier with a public IP address. Connectivity server 125/auto-configuration server 121 may transfer the public IP address of gateway device 114 to wireless application server 124. Wireless application server 124 may start a session timer for the user's session upon receipt of the public IP address of gateway device 114.
Service provider network 120 may create a list of applications that reside on customer home devices 112 (block 1050). For example, wireless application server 124 may send the public IP address of gateway device 114 and the retrieved application profiles to connectivity server 125/auto-configuration server 121. Connectivity server 125/auto-configuration server 121 may connect to each application on customer home devices 112 and determine whether the application is available. In some instances, a customer home device 112-1 through 112-N may be powered down, disconnected, etc. Thus, by connecting to each application, connectivity server 125/auto-configuration server 121 may determine whether the application is available. Connectivity server 125/auto-configuration server 121 may create a list of applications that includes information identifying each application that is determined to be available.
Service provider network 120 may provide the list of applications to customer remote device 130 (block 1060). For example, wireless application server 124 may transmit the application list to customer remote device 130 via network 140.
Customer remote device 130 may display the list of applications to the user. In response, the user may select an application from the list in any known manner.
Service provider network 120 may receive the application selection (block 1070). For example, wireless application server 124 may receive an identifier for an application from customer remote device 130 in response to the user selecting the application. Wireless application server 124 may connect to the application indirectly by, for example, requesting connectivity server 125 to forward the application port(s) on gateway device 114. Connection to the application may involve connectivity server 125/auto-configuration server 121 opening the appropriate port on gateway device 114 for the selected application.
Service provider network 120 may transfer traffic between the selected application and customer remote device 130 (block 1080). For example, wireless application sever 124 may transfer traffic to the application on a customer home device 112-1 through 112-N (through gateway device 114) from customer remote device 130 and to customer remote device 130 from the application. During the transfer, wireless application server 124 may perform protocol conversion. For example, the application may implement a variety of transport protocols. A typical personal computer may support, for example, CIFS/SMB that allows browsing of the file system and reading/writing files. Further, network attached storage devices may implement Network File Server (NFS), CIFS/SMB, FTP, etc. A modern gateway device 114 may implement HTTP/HTTPS on network 140 side and CIFS/SMB on customer home network 110 side.
When wireless application server 124 receives requests from customer remote device 130, wireless application server 124 may invoke a protocol adapter according to the application profile associated with the application selected. For example, if the user-selected customer home device 112-1 through 112-N is a network attached storage device that supports only FTP, wireless application server 124 may translate the requests from customer remote device 130 to FTP commands. If the user-selected customer home device 112-1 through 112-N supports the Universal Plug and Play protocol, wireless application server 124 may invoke a protocol adapter that transforms the requests from customer remote device 130 to, for example, Universal Plug and Play Simple Object Access Protocol (SOAP) methods.
During the transfer of traffic between the selected application and customer remote device 130, wireless application server 124 may also perform data conversion. Whether data conversion is to be performed may depend on the type of data requested by customer remote device 130. When customer remote device 130 interacts with the selected application, customer remote device 130 may send the Multipurpose Internet Mail Extensions (MIME) content type that customer remote device 130 accepts. Wireless application server 124 may receive data from the selected application, invoke the corresponding application, convert the data, and send the converted data to customer remote device 130. Examples of data conversions that may be performed include converting an image from an original format to a format that is acceptable to customer remote device 130 (e.g., to a Graphic Interchange Format (GIF), Joint Photographic Experts Group (JPG) format, Tagged Image File Format (TIFF), Portable Network Graphics (PNG) format, etc.), extracting text from Microsoft Word® and Portable Document Format (PDF) files, converting audio/video files and streams (e.g., Moving Picture Experts Group layer 3 (MP3) format, Qualcomm PureVoice® codec (QCELP), MPEG-4, 3rd Generation Partnership Project (3GPP) format, etc.), etc. Customer remote device 130 may provide information regarding data that is to be sent to customer remote device 130. For example, customer remote device 130 may provide a screen size for MIME “image” content-type data or an amount of “text” type data that customer remote device 130 is capable of receiving. If such information is available to wireless application server 124, wireless application server 124 may take the appropriate action, (e.g., resizing an image, paginating text data, etc.).
The user's session may terminate when the session timer expires. In one embodiment, the session timer may reset every time wireless application server 124 receives a request from customer remote device 130. Thus, the session lasts as long as the user interacts with the selected application. The user's session may further terminate when the user selects another application. In response to the session terminating, service provider network 120 may close the port on gateway device 114 for the selected application.
FIG. 11 is an example of the processing described above with respect to blocks 1010-1040 of FIG. 10. As illustrated in FIG. 11, processing may begin with a user of customer remote device 130 initiating a session by sending a session initiation request, which includes a user identifier, to wireless application server 124 (act 1105). In response, wireless application server 124 may use the user identifier to obtain an identifier for gateway device 114 and identifiers for applications residing on customer home devices 112 from user database 122 (acts 1110, 1115, and 1120). Wireless application server 124 may use the application identifiers to obtain application profile(s) from application database 123 (acts 1125, 1130, and 1135). Wireless application server 124 may send the identifier for gateway device 114 to connectivity server 125/auto-configuration server 121 (act 1140). Connectivity server 125/auto-configuration server 121 may use the identifier of gateway device 114 to look up a public IP address for gateway device 114 (act 1145). Connectivity server 125/auto-configuration server 121 may transfer the public IP address of gateway device 114 to wireless application server 124 (block 1150). In response to receiving the public IP address of gateway device 114, wireless application server 124 may start a session timer (act 1155).
FIG. 12 is an example of the processing described above with respect to block 1050 of FIG. 10. As illustrated in FIG. 12, processing may begin with wireless application server 124 determining whether a first application on customer home devices 112 is available (act 1210). To make this determination, wireless application server 124 may send the public IP address of gateway device 114 and an application profile to connectivity server 125/auto-configuration server 121 (act 1212). Connectivity server 125/auto-configuration server 121 may send a request (e.g., a TR-069-compliant request) to gateway device 114 to request that gateway device 114 open the appropriate port of gateway device 114 for the first application (act 1214). Gateway device 114 may send an acknowledgment indicating that the port has been opened. Connectivity server 125/auto-configuration server 121 may attempt to connect to the first application on customer home devices 112 (act 1216). Connectivity server 125/auto-configuration server 121 may send an indication to wireless application server 124 indicating whether the first application is available (act 1218). Connectivity server 125/auto-configuration server 121 may send a request (e.g., a TR-069-compliant request) to gateway device 114 requesting that gateway device 114 close the port (act 1220).
Wireless application server 124 may perform the above operations for each application in customer home network 110 (act 1230) until the availability of each application has been determined. Connectivity server 125/auto-configuration server 121 may create a list of available applications (act 1240). Wireless application server 124 may transmit the application list to customer remote device 130 (act 1250).
FIG. 13 is an example of the processing described above with respect to blocks 1070-1080 of FIG. 10. Assume that a user of customer remote device 130 selects an application from the list of applications provided by service provider network 120. In response to the selection, customer remote device 130 may provide an identifier for the application and the MIME content type that customer remote device 130 accepts to wireless application server 124 (act 1310). Wireless application server 124 may provide the public IP address of gateway device 114 and the application profile for the received application identifier to connectivity server 125/auto-configuration server 121 (act 1320). Connectivity server 125/auto-configuration server 121 may send a request (e.g., a TR-069-compliant request) to gateway device 114 to request that gateway device 114 open the appropriate port of gateway device 114 for the selected application (act 1330). Gateway device 114 may send an acknowledgment indicating that the port has been opened. In response, wireless application server 124 may establish a connection to the selected application. Thereafter, customer remote device 130 and the selected application may communicate (act 1340). As indicated above with respect to FIG. 10, the transfer of traffic between customer remote device 130 and the selected application may involve the conversion of data from a first format to a second format and/or the conversion of a first protocol to a second protocol.
In response to a request from customer remote device 130 or the user selecting a different application in customer home network 110 (act 1350), connectivity server 125/auto-configuration server 121 may send a request (e.g., a TR-069-compliant request) to gateway device 114 to close the port on gateway device 114 (act 1360). In response, gateway device 114 may close the port.
FIG. 14 is an exemplary process for interacting with an application in customer home network 110 to send an electronic mail (e-mail) message, according to an exemplary embodiment. For this process, assume that, during a session, the user desires to send a binary or image file located on a selected customer home device (e.g., customer home device 112-1) to an e-mail or Multimedia Messaging Service (MMS) recipient. Processing may begin with the user providing a path for the selected file (e.g., by selecting the file) on customer home device 112-1 and the recipient's e-mail or MMS address to wireless application server 124 (act 1410). In response, wireless application server 124 may use the path for the file to obtain the file (acts 1420-1440). Wireless application server 124 may compose the MIME multipart message with, for example, the Content-type set to application/octet-stream, Content-transfer-encoding set to base64, and Content-disposition set to attachment part headers (act 1450). Wireless application server 124 may submit the message to a Simple Mail Transfer Protocol (SMTP) server 1470 for delivery to the e-mail or MMS recipient (act 1460). After submitting the message to SMTP server 1470 for delivery, wireless application server 124 may notify the user of the submission status.
The following example 1500 of FIGS. 15A-15E illustrates the processing described above with respect to FIG. 10. In example 1500, assume that a customer remote device 1510 takes the form of a mobile telephone. Assume further a user of customer remote device 1510 desires to connect to the user's customer home network 110. As illustrated in FIG. 15A, the user may select an action 1520 in a list of actions on a display (e.g., display 530) of customer remote device 1510. In response to the selection, customer remote device 1510 may send a session initiation request to service provider network 120. Service provider 120 may create a list of applications that are available in customer home network 110 and send the list for display on customer remote device 1510, as illustrated in FIG. 15B. Assume that the user selects the application “My PC” 1530 from the list of applications. In response service provider network 120 may establish a connection to a customer home device 1540 that includes the application “My PC,” as illustrated in FIG. 15C.
Assume that the user accesses the “My Documents” folder on customer home device 1540. In response, customer home device 1540 may transmit a list of documents within the “My Documents” folder. Assume that the user selects the image file “Blue hills.jpg” 1550. In response, customer remote device 1510 may transfer information indicating the selection to customer home device 1540. Customer home device 1540 may transfer the selected image file to customer remote device 1510. Upon receipt, customer remote device 1510 may display image 1560, as illustrated in FIG. 15D.
As a second example, assume in FIG. 15C that the user selects the document entitled “D-Link VoD NAT QoS Analysis” in the list of documents in the “My Documents” folder. In response, customer remote device 1510 may transfer information indicating the selection to customer home device 1540. Customer home device 1540 may transfer the selected document to customer remote device 1510. Upon receipt, customer remote device 1510 may display document 1570, as illustrated in FIG. 15E.
Embodiments described herein allow users to remotely connect to applications and documents within the user's home network. A service provider network facilitates the connection of the user's remote device to the home network and the transmission of traffic between the remote device and the home network.
