MECHANISM FOR ESTABLISHING PACKET DATA NETWORK CONNECTION WITH MULTIPLE IP ADDRESSES

摘要

There is provided a mechanism for establishing a single PDN connection with plural IP addresses and breakout or terminating points. When a communication connection provided with multiple IP addresses via a multi-address bearer connection is established, an indication is prepared for indicating a terminating point represented by a network element of the cellular communication network where data traffic, based on one of the multiple IP addresses, is branched to another network being different to the cellular communication network by means of an IP based communication link The indication element is sent to the communication network by means of a PDCP signaling e.g. as a new PDU type code. In the network, it is decided whether a local receiving network element is indicated as a terminating point, wherein in this case a breakout connection to another network being different to the cellular communication network by the IP based communication link is established.

1. A method comprising
preparing establishment of a communication connection to a cellular communication network via a multi-address bearer connection, the communication connection is provided with multiple addresses for Internet protocol based communication links, generating an indication element for indicating at least one terminating point represented by a network element of the cellular communication network where data traffic, based on at least one of the multiple addresses, is branched to another network being different to the cellular communication network by means of one of the Internet protocol based communication links, and causing transmission of the indication element by means of a convergence protocol signaling to a communication network control element of the cellular communication network.
