| 摘要 |
The invention proposes a method and system for handling transmission of packets and/or signalling in a system including a node, e.g. SGSN, for transmitting data packets and/or signalling to another entity or receiving data packets and/or signalling from the another entity, e.g. GGSN. The node has a distributed architecture which includes at least two processing units each having their own address or identifier and being able to transmit and/or receive packets and/or signalling to or from the another entity. The node is adapted to send, in case one or more of its processing units is at least temporarily no longer usable or to be used for sending or receiving packets and/or signalling, information to the another entity for informing the another entity thereon. The information sent from the node to the another entity may contain an address or identifier of another processing unit to be used for receiving and transmitting packets and/or signalling instead of the processing unit no longer to be used. |
