Transmission of location information of a mobile station in a GPRS/internet environment

摘要

A telecommunication network comprising a roaming mobile station (MS) coupled to its Home IP Network (HIPN) via a mobile network MN, a packet-based wireless communication network (GPRS), preferably operating according to the "General Packet Radio Service" ÄGPRSÜ, and an INTERNET. The status and the location of the mobile station MS is indicated by location information or signaling, as the "Routing Area Updates" ÄRAUÜ to the GPRS network and the "Registration Request" messages (RR) to the Home IP network (HIPN), generated by a location signaling circuit (LS) of the mobile station. In order to optimize the transmission of signaling over the radio link (RL) of the mobile network (MN), i.e. to limit as much as possible the load thereon, only the Routing Area Updates are transmitted over the radio link. The Registration Request messages are derived from the Routing Area Updates in the GPRS network and so further transmitted to the Home IP Network (HIPN). IMAGE
