Abstract
The present invention relates to a packet data communication system and a method for use in a packet data communication system. The system includes at least one access network configured to provide a wireless interface between a mobile device and the access network for communication of packet data and a core network including at least one core network node for supporting the communication of packet data on the wireless interface. A controller is provided in association with the access network and configured to monitor at least one condition associated with the wireless interface. If the monitoring indicates that the at least one condition is met, the controller sends messages to the core network node in response to messages from the core network node.
Claims40
A system, comprising:
- at least one access network configured to provide a wireless interface between a mobile device and the at least one access network for communication of packet data;
- a core network comprising at least one core network node configured to support communication of packet data on the wireless interface and configured to release a data communication link associated with the mobile device in the absence of a response to one or more messages directed to the mobile device;
- and
- a controller provided in association with the at least one access network and configured to monitor at least one condition associated with the wireless interface, and, when the monitoring indicates that the at least one condition is met, to generate and send to the core network node one or more messages in response to one or more of said one or more messages from the core network node.

A method, comprising:
- establishing, by a core network node, a data communication link via an access network of a data communication system to a mobile device on a wireless interface between the access network and the mobile device;
- sending one or more messages from the core network node of the data communication system to the mobile device via the access network, wherein the core network is configured to release said data communication link in the absence of a response to said one or more messages;
- detecting at a controller provided in association with the access network that at least one trigger condition associated with the wireless interface is met;
- and
- subsequent to said detection, generating at the controller and sending to the core network node one or more messages in response to said one or more messages from the core network node.

A method, comprising:
- detecting at a controller provided in association with an access network of a data communication system that a mobile device is out of reach, wherein a data communication link is established via the access network to the mobile device on a wireless interface between the access network and the mobile device, wherein a core network node of the data communication system is configured to send one or more messages to the mobile device via the access network, and wherein the core network node is configured to release said data communication link in the absence of a response to said one or more messages;
- and
- notifying, by the controller, said core network node that the mobile device is out of reach, wherein in response to receiving the notification, the core network node is configured to retain said data communication link, to pause from sending further data packets from the core network node to the mobile device, and to process the data packets in accordance with a predefined policy.
A system, comprising:
- establishing means for establishing a data communication link via an access network of the data communication system to a mobile device on a wireless interface between the access network and the mobile device;
- first sending means for sending one or more messages from a core network node of the data communication system to the mobile device via the access network, wherein the core network node is configured to release said data communication link in the absence of a reply to said one or more messages;
- detection means for detection at a controller provided in association with the access network that at least one trigger condition associated with the wireless interface is met;
- and
- second sending means for sending a further message from the controller to the core network node subsequent to such detection, wherein the core network node postpones the release of said data communication link in response to said further message.
2 more elements
A system, comprising:
- an establishing unit configured to establish a data communication link via an access network of the data communication system to a mobile device on a wireless interface between the access network and the mobile device;
- a first sending unit configured to send one or messages from a core network node of the data communication system to the mobile device via the access network, wherein the core network node is configured to release said data communication link in the absence of a reply to said one or more messages;
- a detector configured to detect at a controller provided in association with the access network that at least one trigger condition associated with the wireless interface is met;
- and
- a second sending unit configured to send a further message from the controller to the core network node subsequent to such detection, wherein the core network node postpones the release of said release link in response to said a further message.

- and
- a transmitter configured to, in response to an indication that the at least one condition is not met, generate on behalf of the mobile device and transmit to the core network node one or more messages in response to said one or more messages from the core network node, or configured to, in response to an indication that the at least one condition is not met, generate and transmit to the core network node a message, in response to which the core network node postpones the release of said data communication link.
A method, comprising:
- monitoring, by a controller, at least one condition associated with a wireless interface constituting part of a data communication link between a mobile device and a core network node configured to release said data communication link in the absence of a response to one or more messages directed to the mobile device;
- and
- in response to an indication that the at least one condition is met, either generating, by the controller, on behalf of the mobile device and sending to the core network node one or more messages in response to said one or more messages from the core network node, or otherwise
- sending, by the controller, a message to the core network node in response to which the core network node postpones the release of said data communication link.
