SERVICE LAYER CONTROL AWARE CONTROL SIGNALLING IN A COMMUNICATION NETWORK

摘要

A method and apparatus for handling control signalling between a service layer control node and a Radio Access Network, the signalling being associated with a data flow of a User Equipment, the User Equipment being associated with a Radio Access Network node. The Radio Access Network node receives a data flow comprising a plurality of data packets sent using a bearer towards the User Equipment. It determines whether a data packet in the data flow includes an identifier indicating that the data packet relates to control signalling. A data packet that is found to relate to control signalling is removed from the data flow, to produce a modified data flow, which is sent towards the User Equipment. This allows the Radio Access Network node to become aware of control related signalling such that it can be processed.
