1. A method, comprising:
- receiving by a terminal a notification about a power saving mode of a further terminal;
providing to a network by a protocol stack of said terminal a communication signal intended for said further terminal by transmitting said communication signal according to a pre-selected procedure for communicating of said terminal with said further terminal through said network in a power constrained environment using a communication application available in said terminal; and
receiving by said terminal, after said further terminal is woken up, an acknowledgement of receiving said communication signal by said further terminal, wherein said terminal waits for said acknowledgement at least for a time interval needed for said further terminal to wake up before terminating communicating based on a predetermined criterion facilitated by said communication application of said terminal.

Abstract
This invention describes a method for expanding universal plug and play capabilities in a power constrained environment thus facilitating communication between two terminals with universal plug and play (UPnP) application capabilities, wherein one of the terminals is in a sleeping mode. The present invention can be applied (but not be limited) to mobile terminals, wireless devices, portable devices, mobile communication devices, mobile phones, etc. The invention describes a mechanism in which the UPnP application dynamically instructs the TCP/IP stack to tune-up its parameters so that it can tolerate longer delays and timeouts, due to the fact that it operates in a power constrained UPnP environment.

13. A terminal, comprising:
-
a non-transitory computer readable medium encoded with a data structure embodying a protocol stack, responsive to a notification about a power saving mode of a further terminal configured to provide to a network a communication signal intended for said further terminal by transmitting said communication signal according to a pre-selected procedure for communicating with said further terminal through said network in a power constrained environment; a communication application configured to provide to said protocol stack instructions according to a predetermined criterion defining a waiting period for receiving an acknowledgement of receiving said communication signal by said further terminal after said further terminal is woken up, wherein said waiting period is at least as long as a time interval needed for said further terminal to wake up. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A communication system, comprising:
-
a further terminal being a power saving mode, responsive to a wake up call; a terminal, responsive to a notification about a power saving mode of said further terminal, configured to provide a communication signal intended for said further terminal by transmitting said communication signal according to a pre-selected procedure for providing communicating in a power constrained environment, configured to provide instructions for a predetermined criterion defining a waiting period for receiving an acknowledgement of receiving said communication signal by said further terminal after said further terminal is woken up, wherein said waiting period is at least as long as a time interval needed for said further terminal to wake up; a network, configured to provide said notification, configured to provide said wake up call for waking up said further terminal in response to said communication signal, configured to facilitate sending signals between said terminal and said further terminal, wherein a universal plug and play application is available in said terminal and said further terminal. - View Dependent Claims (24)

25. A method, comprising:
-
receiving by a terminal a notification about a power saving mode of a further terminal; providing to a network by a protocol stack of said terminal a communication signal intended for said further terminal by transmitting said communication signal according to a pre-selected procedure for communicating with said further terminal through said network in a power constrained environment using a communication application available in said terminal and said further terminal; detecting said communication signal and starting a wake-up process of said further terminal in response to said communication signal; and receiving, after said further terminal is woken up, said communication signal by said further terminal and sending an acknowledgement of receiving said communication signal to said terminal by said further terminal, wherein said terminal waits for said acknowledgement at least for a time interval needed for said further terminal to wake up before terminating communicating based on a predetermined criterion facilitated by said communication application of said terminal. - View Dependent Claims (26)
