| 摘要 |
The invention relates to a method, a system and a network element for controlling data transmission in a network environment comprising a first control function I-CSCF 206 and a second control function S-CSCF 203. In order to optimise the network resource usage the second control function S-CSCF 203 is allocated by said first control function I-CSCF 206 dynamically when a network transaction is processed. Thus, network resources are saved as a permanent allocation of the second control function S-CSCF 203 is avoided.
