Remote terminal 30 is operated according to the input of user generates catalogue browsing order, includes the mark of target household NAS device 20 in the order.For example, the catalogue browsing order can be expressed as " GET NAS1/DIR ", wherein NAS1 is the mark of target NAS, and DIR shows request browsing NAS1's File directory (English: directory, DIR).
Then, remote terminal 30 is connect by second between remotely administered server 40, which is sent to remotely administered server 40.
Step 102: catalogue browsing order is forwarded to home gateway by the first connection by remotely administered server.
Specifically, home gateway 10 establishes the first connection by previously described mode, by the account and remotely administered server 40 that log in remotely administered server 40, not repeat herein.
In actual conditions, each remotely administered server 40 can be to distribute to a fixed dedicated server of home gateway 10, in this case, remotely administered server 40 is after the catalogue browsing order for receiving the transmission of remote terminal 30, since the home gateway 10 of self-management is unique, by the first connection between remotely administered server 40 and the home gateway 10, which is sent to the home gateway 10.
And when each remotely administered server 40 is responsible for managing multiple home gateways 10, remotely administered server 40 receives after the catalogue browsing order of the transmission of remote terminal 30, it is thus necessary to determine that should forward the command to which home gateway 10.A kind of implementation are as follows: include the mark of home gateway 10 in the catalogue browsing order, remotely administered server 40 is identified according to the home gateway 10 in catalogue browsing order, sends the command to corresponding home gateway 10.In another implementation, the mapping relations of the home gateway 10 and remote terminal 30 that log in by same account are preserved in remotely administered server 40, it include the mark of the remote terminal 30 as order source in the catalogue browsing order that remote terminal 30 is sent, remotely administered server 40 is according to the mapping relations locally saved, it determines and sends home gateway 10 corresponding to the remote terminal 30 of order, and catalogue browsing order is sent to home gateway 10.
Step 103: home gateway is connected by third the file directory of family's NAS device being sent to File Agent server according to catalogue browsing order.
Specifically, home gateway 10 by previously described one to thirdly in any mode establish third with File Agent server 50 and connect, refuse repetition herein.
In actual conditions, remote terminal 30 requests networked storage units of the family's NAS device 20 of browsing catalogue built in home gateway 10, and in this case, home gateway 10 has to family's NAS device 20 Control authority, can be connected by third and the file directory of family's NAS device 20 is sent to File Agent server 50.
And when family's NAS device 20 is positioned at the autonomous device of the LAN side of home gateway 10, the catalogue that home gateway 10 obtains family's NAS device 20 includes two kinds of implementations:
Mode 1, home gateway 10 have the permission that file or catalogue are read from family's NAS device 20, then home gateway 10 directly reads file directory from family's NAS device 20, and file directory is sent to File Agent server 50.
Received catalogue browsing order is transmitted to family's NAS device 20 by mode 2, home gateway 10, and family's NAS device 20 responds the catalogue browsing order, file directory is sent to home gateway 10.After home gateway 10 receives the file directory of the transmission of family's NAS device 20, is connected by third and this document catalogue is sent to File Agent server 50.
Step 104: remote terminal obtains the file directory of family's NAS device by the 4th connection from File Agent server.
It connect specifically, remote terminal 30 establishes the 4th with File Agent server 50 by previously described mode, not repeats herein.In actual conditions, step 104 has a variety of implementations, comprising:
The first implementation: home gateway 10 connects to the transmission of remotely administered server 40 catalogue by first after the file directory of family's NAS device 20 is sent to File Agent server 50 and is sent completely notice；Catalogue is sent completely notice by the second connection and is sent to remote terminal 30 by remotely administered server 40.Remote terminal 30 receives the catalogue and is sent completely notice, it connects by the 4th to File Agent server 50 and sends catalogue browsing request, File Agent server 50 responds catalogue browsing request, sends to remote terminal 30 from the received this document catalogue of home gateway 10.
In this implementation, remote terminal 30 can know whether the file directory of family's NAS device 20 is successfully uploaded to File Agent server 50 accurately and in time, so that remote terminal 30 can obtain this document catalogue from File Agent server 50 in time.
It should be noted that, remotely administered server 40 can be when being sent completely notice to the transmission of remote terminal 30 catalogue, the address of File Agent server 50 is sent to remote terminal 30, File Agent server 50 is established the 4th with File Agent server 50 according to the address and is connect, and connects by the 4th to text Part proxy server 50 sends file directory request.
Second of implementation: remote terminal 30 periodically sends file directory request to File Agent server 50 after sending the catalogue browsing order to remotely administered server 40.Once File Agent server 50 receives the file directory of the transmission of home gateway 10, then File Agent server 50 can send this document catalogue to remote terminal 30 after this document catalog request for receiving the transmission of remote terminal 30.
The third implementation: remote terminal 30 is connected as long connection with the 4th of the foundation of File Agent server 50, remote terminal 30 is sending the rear to the transmission file directory request of File Agent server 50 of the catalogue browsing order to remotely administered server 40, with second of implementation the difference is that, remote terminal 30 can only send a file directory request, File Agent server 50 is after the file directory for receiving the transmission of home gateway 10, this document catalog request can be responded, file directory is actively sent to by remote terminal 30 by the 4th connection.
4th kind of implementation: remote terminal 30 is connected as long connection with the 4th of the foundation of File Agent server 50, and establishes connection between remotely administered server 40 and File Agent server 50.Remotely administered server 40 is after the catalogue browsing order for receiving the transmission of remote terminal 30, on the one hand the catalogue browsing order is transmitted to home gateway 10, on the one hand the catalogue browsing order is sent to File Agent server 50, which includes the mark of remote terminal 30 and the mark of home gateway 10.File Agent server 50 is after the file directory for receiving the home gateway 10 transmission, according to catalogue browsing order it is determined that this document catalogue is sent to remote terminal 30, then it is connect by the 4th between remote terminal 30 and file directory is sent to remote terminal 30.
Step 105: remote terminal shows the file directory of family's NAS device.
Specifically, remote terminal 30 shows this document catalogue by the display unit of remote terminal 30 after the file that File Agent server 50 obtains family's NAS device 20, the file directory for viewing family's NAS device 20 is allowed users to.
In above-mentioned technical proposal, home gateway 10 and remotely administered server 40 establish the first connection, remote terminal 30 and remotely administered server 40 establish the second connection, in this way, catalogue browsing order can be sent to home gateway 10 by remotely administered server 40 by remote terminal 30.And home gateway 10 and text Part proxy server 50 establishes third connection, remote terminal 30 is established the 4th with File Agent server 50 and is connect, in this way, home gateway 10 is able to respond received catalogue browsing order, the file directory of family's NAS device 20 is sent to by remote terminal 30 by File Agent server 50.The IP address that above-mentioned technical proposal is not only suitable for the WAN of home gateway 10 is the situation of public network address, and the IP address for being also applied for the WAN of home gateway 10 is the situation of private net address, applied widely.Moreover, in above-mentioned technical proposal, remote terminal 30 sends catalogue browsing order to home gateway 10 by the existing remotely administered server 40 being managed to home gateway 10, not only implementation is simple, and cost is relatively low, is conducive to the extensive use that remote terminal 30 accesses 20 technology of family's NAS device.Furthermore the catalogue of family's NAS device 20 only when remote terminal 30 issues catalogue browsing order, is sent to File Agent server 50 by home gateway 10, and the file of family's NAS device 20 is then still only stored in family's NAS device 20, and safety is higher.
In one possible implementation, remote terminal 30 can further access the file of family's NAS device 20 after the file directory that family's NAS device 20 is accessed through the above way.Referring to Fig. 3, remote terminal 30 accesses the process of the file of family's NAS device 20, includes the following steps:
Step 106: remote terminal generates file access command according to the first of user the input operation, and file access command is used to access the first file in the file directory of family's NAS device.
Specifically, remote terminal 30 is after the file directory of display family's NAS device 20, user can view the file directory of family's NAS device 20, user can carry out choosing operation to the first file in catalogue, remote terminal 30 chooses operation according to this of user, generates the file access command to access to first file.
For example, the first file shown on user's touch sensitive display unit, remote terminal 30 will be used to access the file access command of the first file according to touch operation generation when the display unit of remote terminal 30 is touch screen.In another example the cursor that mobile remote terminal 30 is shown is moved to the first file by user, and determination key is pressed to choose the first file, remote terminal 30 will be used to access the file access command of the first file according to the generation.In another example the microphone of user against remote terminal 30 is said " the first file ", remote terminal 30 generates the file access command of the first file of access after the voice of parsing user's input.
In actual conditions, this document visit order can be expressed as " GET NAS1/FILE1 ", wherein NAS1 The as mark of target NAS, FILE1 are the mark of the first file.
Step 107: remote terminal connects to remotely administered server by second and sends file access command.
Step 108: file access command is sent to home gateway by the first connection by remotely administered server.
