Method and node for the set-up of a connection in a telecommunication network
First Claim
1. Method for the set-up of a connection in a communication network, wherein the set-up is initiated with an initial message from an originating control node to a terminating control node of the connection and the establishment of a bearer for the connection is initiated according to a reply to the initial message, wherein a control timer is started according to the initial message and wherein an expiry of the control timer (CT) before an indication of the bearer establishment triggers a release of the connection, comprising the steps of:
- receiving the initial message at the terminating control node, paging a user equipment for the connection and starting a first timer (FT) according to the paging initiation, the expiry value of the first timer (FT) being set lower than the expiry value of the control timer (CT), initiating the bearer establishment for the connection upon expiry of the first timer (FT), stopping the control timer (CT) upon reception of an indication of the bearer establishment.

Abstract
In a method for the set-up of a connection in a communication network, the set-up is initiated with an initial message (12) from an originating control node (ON) to a terminating control node (TN) of the connection and the establishment of a bearer for the connection is initiated according to a reply to the initial message (12). A control timer (CT) is started according to the initial message (12) and an expiry of the control timer (CT) before an indication of the bearer establishment triggers a release for the connection. In the method, after receiving the initial message (12) at the terminating control node (TN), a paging (13) a user equipment (UE) for the connection and starting a first timer (FT) according to the paging (13) initiation is performed, the expiry value of the first timer (FT) being set lower than the expiry value of the control timer (CT). The bearer establishment for the connection is initiated upon expiry of the first timer (FT) and the control timer (CT) is stopped upon reception of an indication of the bearer establishment. Devices and software programs embodying the invention are also described

11. Terminating control node in a communication network, wherein a set-up of a connection is initiated with an initial message from an originating control node to the terminating control node of the connection and the establishment of a bearer for the connection is initiated according to a reply to the initial message, wherein a control timer (CT) is started according to the initial message (12) and wherein an expiry of the control timer (CT) before an indication of the bearer establishment triggers a release of the connection, the terminating control node being provided with an interface for receiving and sending messages and a processing system for processing the messages, wherein the terminating control node is adapted to receive the initial message from an originating control node for the set-up of the connection and to send the reply to the initial message for initiating the establishment of the bearer for the connection, wherein the terminating control node is adapted to initiate a paging of a user equipment for the connection, wherein the terminating control node comprising:
-
a first timer (FT) and the processing system is adapted to start the first timer (FT) according to the paging, the expiry value of the first timer (FT) being set to a predefined value lower than the expiry value of the control timer (CT), and means for sending a bearer information message towards the originating control node upon expiry of the first timer, the bearer information message initiating the establishment of a bearer for the connection.

12. Program unit adapted to the execution in a processing system of a terminating control node in a communication network, wherein a set-up of a connection is initiated with an initial message from an originating control node to the terminating control node of the connection and the establishment of a bearer for the connection is initiated according to a reply to the initial message, wherein a control timer (CT) is started according to the initial message and wherein an expiry of the control timer (CT) before an indication of the bearer establishment triggers a release of the connection, the terminating control node being provided with an interface for receiving and sending messages and the processing system, wherein the terminating control node is adapted to receive the initial message from the originating control node for the set-up of the connection and to send the reply to the initial message for initiating the establishment of the bearer for the connection, wherein the terminating control node is adapted to initiate a paging of a user equipment for the connection, wherein the program unit comprises code adapted to start a first timer (FT) according to the paging, the expiry value of the first timer (FT) being set to a predefined value lower than the expiry value of the control timer (CT), and the program unit comprises code adapted to send a bearer information message towards the originating control node upon expiry of the first timer, the bearer information message initiating the establishment of a bearer for the connection.
