Command from Server to my Arduino with GSM connection (client)

Official Hardware Retired GSM Shield

Hi all,
I'am using Arduino MEGA2560 and SIM908 GSM/GPRS/GPS module.

I have programmed my Arduino board as Client for the communication to comply to imposed network infrastructure. So I have configured SIM908 module by AT command to make HTTP request (GET and POST) to the Server.

All works satisfactorily, but now it became necessary that the Server must send a command to my board (client) occasionally during the normal communication already tested as described above.

How can I do it ?
How can I configure my Client's gsm modem ?
Must a request start always from Client necessarily so that the Server send a command to Client?

I think you have already faced this problem... which technique have you used ?

Thanks a lot!
bye!
Antonio

Best bet is to connect to the server periodically and check for new commands. Some people use SMS as a way to tell their board to connect.
