Connections in a comunication system
First Claim
1. A method in a communication system comprising:
- establishing simultaneous circuit switched and packet switched connections between an user equipment and a first element of the communication system;
initiating a procedure to hand the circuit switched connection over from the first element to a second element of the communication system;
monitoring for a predefined event, the event being defined to indicate a need for release of resources reserved by the packet switched connection; and
subsequent to detection of the event, releasing resources reserved by said packed switched connection.

Abstract
The present invention relates to a communication system and a method for the same. In the method simultaneous circuit switched and packet switched connections are established between a user equipment and a first element of the communication system. A predefined event is monitored for after initiation of a procedure for handing the circuit switched connection over from the first element to a second element of the communication system. The event is defined to indicate a need for release of resources reserved by the packet switched connection. Subsequent to detection of the event, resources reserved by said packet switched connection at the network side of the system are released.

27. A communication system comprising:
-
user equipment;
a first controller, wherein simultaneous circuit switched and packet switched connections are enabled between the user equipment and the first controller;
a second controller, wherein the circuit switched connection can be handed over from the first controller to the second controller; and
means for detecting a predefined event, wherein the system is arranged, in response to the detection of the event, to release resources reserved by the packet switched connection. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 37, 38, 39, 40)
