  • Method and apparatus for a fast installation of an IP user connection over a 3GPP NB interface under application of the bICC “delayed backward bearer establishment” and avoidance of failure
    Patent number: 8265088
    Abstract: An IP user data transport connection is established between a Media Gateway O and a Media Gateway T according to the BICC “Delayed Backward Bearer Establishment”. The Media Gateway O sends an IPBCP Accepted message towards the Media Gateway T upon receipt of an IPBCP Request message from Media Gateway T. The Media Gateway O sends data within the user data transport connection towards the Media Gateway T. The user data may arrive at the Media Gateway T before the IPBCP accepted message. The Media Gateway T retrieves the source IP address and Port number from a user data transport connection IP packet received the Media Gateway O, and sends the first user data transport connection IP packet(s) towards the Media Gateway O upon receipt of a user data transport connection IP packet from the Media Gateway O, using the retrieved IP Address and Port number as destination.
