Enhanced application of operational information

摘要

A method for enhancing application of operational information in a communication system. A channel (CH) is allocated for a connection between a user terminal (UT1) and at least one other user terminal (UT2). Operational information (posi) on the user of the user terminal (UT1) is determined and included in a data item (DI) of a user plane signaling message. The user plane signaling message is transmitted to the at least the other user terminal in a timeslot stolen from the channel (CH) allocated to the connection. Delivery of operational information between users is facilitated with reduced overhead and without essentially incurring additional load to the radio interface between the user terminals.
