Techniques to enable firewall bypass for open mobile alliance device management server-initiated notifications in wireless networks

Abstract

An embodiment of the present invention provides a method, comprising enabling firewall bypass for open mobile alliance device management (OMA DM) server-initiated notifications in wireless networks by requiring that a certain OMA DM packet is captured by a modem associated with a OMA DM client and routed via a predetermined driver interface, wherein the OMA DM server initiates connection with the OMA DM client by sending a UDP packet to the OMA DM client inside a wireless device, and wherein the OMA DM packet is transferred over RF channel into a the modem, and through the wireless device OS's IP stack delivered to an application of the OMA DM client.

1 . A method, comprising:
 sending by an open mobile alliance device management (OMA DM) server a UDP packet to an OMA DM client inside a wireless device to initiate connection;   capturing by a modem associated with the OMA DM client a certain OMA DM packet in the UDP packet; and   enabling firewall bypass by requiring that the certain OMA DM packet be routed via a predetermined driver interface and through an IP stack delivered to an application of said OMA DM client;   wherein said OMA DM packet is transferred over RF channel to said modem.   
     
     
         2 . The method of  claim 1 , wherein said OMA DM packet is an IP packet. 
     
     
         3 . The method of  claim 1 , wherein said predetermined driver interface is the IoCTL driver interface. 
     
     
         4 . The method of  claim 3 , wherein said modem or its related drivers monitors incoming UDP packets and intercepts said OMA DM packets instead or in addition to submitting bootstrap/package 0 packets to a normal IP stack, said modem also sends the information across the proprietary driver's IOCTL control interface into a control stack and from there to said OMA DM client application. 
     
     
         5 . The method of  claim 4 , wherein the interception of said packets is by port number or by pattern matching the data of the UDP packet or by comparing the UDP source IP address to a pre-set IP address of said OMA DM server which the OMA DM client pre-sets in the modem. 
     
     
         6 . A system, comprising:
 an open mobile alliance device management (OMA DM) server; and   a wireless client operable to communicate with said OMA DM server over a wireless network to enable firewall bypass by:   receiving from the OMA DM server a UDP packet to initiate connection;   capturing by a modem a certain OMA DM packet in the UDP packet;   routing the OMA DM packet via a predetermined driver interface and through an IP stack delivered to an application of the wireless client.   
     
     
         7 . The system of  claim 6 , wherein said OMA DM packet is an IP packet. 
     
     
         8 . The system of  claim 6 , wherein said predetermined driver interface is a IoCTL driver interface. 
     
     
         9 . The system of  claim 6 , wherein said OMA DM server initiates connection with said OMA DM client by sending a UDP packet to the OMA DM client inside a wireless device. 
     
     
         10 . The system of  claim 9 , wherein said OMA DM packet is transferred over RF into a modem and through said wireless device OS's IP stack delivered to an application of said OMA DM client. 
     
     
         11 . The system of  claim 10 , wherein said modem monitors incoming UDP packets and intercepts said OMA DM packets and instead or in addition to submitting bootstrap/package 0 packets to a normal IP stack, said modem also sends the information across the proprietary driver's IoCTL control interface into the control stack and from there to said OMA DM client application. 
     
     
         12 . The system of  claim 11 , wherein the interception of said packets is by port number or by pattern matching the data of the UDP packet or by comparing the UDP source IP address to a pre-set IP address of said OMA DM server which the OMA DM client pre-sets in the modem. 
     
     
         13 . A apparatus, comprising:
 a wireless device operable to communicate with a OMA DM server over a wireless network and capable of enabling firewall bypass by:   capturing by a modem a certain OMA DM packet in an UDP packet from the OMA DM server;   routing the OMA DM packet via a predetermined driver interface and through an IP stack delivered to an application of the wireless device.   
     
     
         14 . The apparatus of  claim 13 , wherein said OMA DM packet is an IP packet. 
     
     
         15 . The apparatus of  claim 14 , wherein said predetermined driver interface is the IoCTL driver interface. 
     
     
         16 . The apparatus of  claim 15 , wherein said OMA DM server initiates connection with said wireless device by sending a UDP packet to the wireless device. 
     
     
         17 . The apparatus of  claim 16 , wherein said OMA DM packet is transferred over RF into said modem, and through said wireless device OS's IP stack. 
     
     
         18 . The apparatus of  claim 17 , wherein said modem monitors incoming UDP packets and intercepts said OMA DM packets and instead or in addition to submitting bootstrap/package 0 packets to a normal IP stack, said modem also sends the information across the proprietary driver's IOCTL control interface into the control stack and from there to said wireless client.
