Monitoring connection to user terminal in telecommunications system
First Claim
1. A method for monitoring a connection to a user terminal in a telecommunications system in which an element controlling the connection is separate from a system part providing transport of user data, the method comprising:
- sending an indication message indicating the state of the connection to the user terminal to the controlling element from a system element which knows the state of the connection, and deciding in the controlling element the state of the connection to the user terminal based on the indication message received.

Abstract
A method for monitoring a connection to a user terminal in a telecommunications system and a telecommunications system comprising an element (CSCF) controlling a connection to a user terminal (UE) and a system part (SGSN, GGSN) providing transport of user data, which system part is separate from said controlling element, wherein a system element which knows the state of the connection to the user terminal (UE) is arranged to send an indication message to the controlling element (CSCF) indicating the state of the connection, and the controlling element (CSCF) is arranged to decide the state of the connection to the user terminal (UE) based on the indication message received.

18. A telecommunications system comprising:
-
an element controlling a connection to a user terminal;
a system part providing transport of user data, which system part is separate from said controlling element; and
a system element which knows the state of the connection to the user terminal, the system element being configured to send an indication message to the controlling element indicating the state of the connection, and wherein the controlling element is configured to decide the state of the connection to the user terminal based on the indication message received. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

- 35. An element controlling a connection to a user terminal in a telecommunications system in which said controlling element is separate from a system part providing transport of user data, wherein the controlling element is configured to decide the state of the connection to the user terminal based on an indication message received from a system element which knows the state of the connection to the user terminal.
- 45. A system element which knows the state of a connection to a user terminal in a telecommunications system in which a controlling element controlling a connection to the user terminal is separate from a system part providing transport of user data, wherein the system element is configured to send an indication message to the controlling element indicating the state of the connection to the user terminal.
