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.
A method in a communication system comprising:
A method as claimed in any preceding claim, wherein the event is detected before the user equipment generates a request for an update of information that associates with the radio access entity serving the user equipment.
A method as claimed in any preceding claim, wherein the first element is a radio network controller of a first communication network and the second element is a radio network controller of a second communication network.
A method as claimed in any preceding claim, wherein the first element and the second element operate based on different technologies.
A method as claimed in any preceding claim, wherein the event comprises a request to release resources which associate with the circuit switched connection.
A method as claimed in claim 12, wherein the request is generated by an element of the core network of the communication system.
A method as claimed in any of the preceding claims, wherein the first element generates a request for release of resources in response to detection of the event.
A method as claimed in any preceding claim, wherein the event comprises a decision to release the resources, said decision being based on information of the capabilities of the communication network to which the second element belongs.
A method as claimed in any preceding claim, wherein the event comprises an indication from a timer function.
A method as claimed in claim 19, wherein the timer function is implemented in the first element.
A method as claimed in any preceding claim, comprising step of storing data that associates with the connection to be released.
A communication system comprising:
A communication system as claimed in any of claims to 27 to 35, wherein the first element is adapted to make the decision to release the resources.
Dependencies are inferred from the claim text.
