20100220703 | METHOD AND SYSTEM FOR CONTROLLING CALL ADMISSION IN IMS - A method and a system for controlling call admission for parallel ringing processes to a realm in an IMS is disclosed. The method comprises receiving a call control message to a called party, determining whether the called party has parallel ringing enabled, if positive, generating a plurality of parallel call control messages, associating to each parallel call control message a parallel ringing identifier indicating that the corresponding call control message is a parallel call control message, receiving a plurality of call control messages directed towards the realm, performing call admission control for this realm by verifying whether a parallel ringing identifier is associated to each call control message directed towards this realm so as to determine if the call control message is a parallel call control message. | 09-02-2010 |
20100223492 | NODE FAILURE DETECTION SYSTEM AND METHOD FOR SIP SESSIONS IN COMMUNICATION NETWORKS - The present invention relates to a failure detection method and system operating at the session control layer, preferably within an IMS/SIP architecture, which monitors the status of an adjacent node with the aid of a timer mechanism that sets a heartbeat rate associated with that adjacent node. Monitoring of a communication session takes place by monitoring the liveliness of the nodes handling the session. | 09-02-2010 |
20110211465 | TELECOMMUNICATIONS NETWORK - In a telecommunications network including a gateway network element in communication with a control system and a user device, a system and method of controlling a data consumption rate of the user device including: a first control system node periodically transmitting a command to a second control system node, the message including information relating to a user's data usage, received from the gateway network node; in response to each command, the second control system node transmitting a reply message to the first control system node; controlling the transmission of the periodic commands according to a variable time interval; and the second control system node using the data usage information received in the periodic reply messages to control the data consumption of the user device. Preferably the control system conforms to a 3GPP Policy Charging Control Architecture and the first node is a PCEF and the second node is a PCRF. It is also preferable that the command is a DIAMETER protocol Accounting Request (ACR) command and the reply message is a DIAMETER protocol Accounting Answer (ACA) message. | 09-01-2011 |
