Data transmission in packet-switched radio system implementing user equipment location service

A method for transmitting data in a packet-switched radio system implementing a user equipment location service, wherein the data is transmitted using a data transmission link between user equipment of the radio system and a serving mobile location center of a radio network of the radio system, the user equipment and the serving mobile location center constituting first and second parties of the data transmission link, and in the method

• the data to be transmitted is placed in a message of a third-layer radio resource protocol set on top of a packet protocol stack residing in the first party of the data transmission link,
• the radio resource protocol message is transmitted to the radio network using a logical link control protocol set on the second layer of the packet protocol stack,
• a logical link control protocol relay set on the second layer of the packet protocol stack in the radio network directs the logical link protocol message to the second party of the data transmission link,
• the second-layer logical link control protocol residing in the second party of the data transmission link and set on the packet protocol stack transmits the radio resource protocol message to the radio resource protocol set on the third layer, and
• the second party of the data transmission link disassembles the transmitted data from the radio resource protocol message.
