Abstract:
1. A method of transferring a message comprising routing information relating to an intended recipient of the message and content information from a first node via a second node to a third node in an Internet Protocol Multimedia Subsystem (IMS) communications network, wherein a repository is associated with the second node, wherein the second node and the third node each are one of a Proxy Call Session Control Function (P-CSCF) node and an Interconnection Border Control Function (IBCF) node, and wherein at least one network node that is within the IMS communications network is disposed in the communications network between the second node and the third node, the method comprising: receiving the message from the first node by the second node; storing data representative of the content information in the repository associated with the second node; replacing, by the second node, in the message, the content information by a token; transmitting the message, comprising the routing information and the token, from the second node to the third node via the at least one network node disposed between the second node and the third node to save bandwidth consumption; responsive to receiving the message, retrieving, by the third node, the content information based on the token directly from the second node without going through the at least one network node disposed between the second node and the third node such that the content information is transported by fewer nodes in the IMS communications network than the message comprising the token; and replacing by the third node, in the message, the token by the content information and transferring the message comprising the content information to a recipient over the communications network.
