Mobile telecommunication systems such as General Packet Radio Service (GPRS) and Universal Mobile Telecommunications System (UMTS) provide packetswitched service for mobile terminals. 3GPP Release 4 and Release 5 further offer packet voice over a GPRS/UMTS infrastructure so that IP based communications between mobile to mobile is expected to be one of the major traffic types in the future 3G Al...

In this paper we analyse the provision of enhanced communications between vehicles. It is expected that vehicles will have several communication devices, and that a specialised node will provide external connectivity to these devices, i.e. the devices in the vehicle form a Mobile Network. We propose the use of Network Mobility communication solutions for providing access from the vehicles to an...
