RAC Remote Configuration (02-Feb-2010)
The idea is to design a new method to remotely configure the RAC and authorize this person to access his home network. The following is the remote configuration process: 1. The home network owner (RAC A) uses the https connection to login the web server on RAS by browser. 2. The owner authorizes user B (RAC B) to access his home network and RAS assigns a user name and password for user B. 3. User B logins the web server using the assigned user name and password. 4. User B requests to download the credential files. 5. RAS web server requests the credential files from RAMC. 6. RAMC generates the credential files and delivers the credential files to RAS web server. 7. User B receives the configuration profile and credential files to his mobile. 8. User B uses the profile and credential files to establish the secure tunnel. 9. User B can communicate with the RAS in the home network, RAS sync the device info in home network to RAC B. 10. Then RAC B can browse the media content of media server in the home network.

ABSTRACT
The present embodiments provide a method for remotely configuring the Remote Access Client (RAC) and authorizing this user to access the home network, the method including: assigning user name and password for other user on Remote Access Server (RAS); generating the credential files for the user by Remote Access Management Console (RAMC); getting configuration profile and credential files from RAS, which is used to establish the secure tunnel with RAS.
In this way, the home network owner could more easily and conveniently configure other user’s RAC, not necessary to configure the person’s RAC in his home network.
PROBLEM
UPnP technology was envisioned to be deployed in local area networks. This initial design goal leads to some decisions which will pose some challenges when trying to expand the original scope of the UPnP technology beyond the physical boundaries of local area networks such as those found at home. For example, the discovery step described in UPnP Device Architecture v1.0 involves multicast messages that will be difficult to forward them beyond the home network due to the fact that a typical internet router will discard such messages. [Ref 2]
Figure 1: UPnP Remote Access
Before an UPnP device can be used remotely, the user has to configure the Remote Access Server (RAS) and the Remote Access Client (RAC) devices so that they can establish a Remote Access Transport channel between them. This step is considered to be the Remote Access Setup phase and has to be taken place while both RAC and RAS are in the home network. And this configuration process is taken by Remote Access Management Console (RAMC). [Ref 2]

In this way, there is inconvenience for the other user wants to remotely access the home network. For example, a person(A) remotely access his own home network by mobile and show some pictures to his friend(B), then his friend is interesting with these pictures and wants to access these pictures by his own mobile. At this time, in order to access the home network, the following procedure should be taken:
1. The person B firstly installs the RAC software on his mobile.
2. The person A brings the person B’s mobile to his home and connects to his home network.
3. The person A uses the RAMC to configure the RAC on the person B’s mobile.
4. The person A returns the mobile to person B.
5. The person B can use his mobile to access the perso...
