Abstract

A location information (li) which is available in a mobile terminal device (ME-T) and which indicates the geographical location of the terminal device (ME-T) is embedded in messages (m) of a SIP protocol (SIP) which are exchanged between the terminal device (ME-T) and the network (WLAN) during the establishment of a session and/or during a session and/or during the registration of a terminal device (ME-T) in the network (WLAN), e.g. LAN or UMTS, or during request of a service or a function. By advantageously complementing the SIP protocol (session initiation protocol), the location information can be transmitted from a mobile terminal device (ME-T), which optionally has a telephone function, to the network (WLAN) in any signaling state, thereby substantially reducing the economic outlay for implementing the transmission of location information (li) to the network (WLAN).
