UUNet says IPv4 may hold key to GPRS roaming By Simon Marshall, Total Telecom 22 August 2000 A mobile specialist from WorldCom subsidiary UUNet has told Total Telecom that although IPv6 would be a more suitable network solution for GPRS roaming, its implementation will probably be stalled in favor of souped-up IPv4 options. Speaking on the development of GPRS Gateway Support Nodes (GGSN) at a London conference organized by the GSM Association, UUNet mobile technology development specialist Nick Hutton said he doubted that IP version 6 would be deployed at the edge of the network. "IPv6 will allow roaming without the need for IPv4, effectively solving the problem of fixed IP addresses in a mobile world. "But I doubt IPv6 will make it out to the edge of the network, where the handsets are. Operators have been retro-fitting protocols such as MPLS and RSVP from IPv6 to IPv4 for some time, and DNS [Domain Name System] could well be used by operators to solve the problem using IPv4. It's a little known fact that over 60% of IP addresses are still available to be used by IPv4," added Hutton. Currently, IPv4 only allows IP addresses that are geographically fixed. Greater latency is introduced in mobile roaming calls as the distance from the geographical location of the IP address increases. GGSN technology acts as a proxy server, translating SS7 circuit-switched traffic to IP traffic on carrier networks. More than 400 mobile specialists from operators and vendors around the world attended the event, the first time the GSM Association has organized an event specifically for industry executives focussed on the development of GPRS services and networks.

CR - UK 3-G licenses, upgrades allowed and Korea. spectrumauctions.gov.uk Something has been bothering me about these 3-G licenses in Europe and now in Korea. I looked at the UK Radio Agency website and found as best as I could the details of the new licenses being offered. The document appeared to me to say that exisitng systems wouldl also be allowed to carry HDR traffic provided they were only fitted with upgrades in order to do so. It seems to me quite important since especially in Korea where there is an existing CDMA-one system in operation then it can be upgraded to cdma2000. It would seem quite difficult to me to limit an operator to the speed of data that he can send over his network. The new licensees might understand that they are not being licensed to remove existing operators but that the data rates they have just won are for data rates that can only be achieved with the euiqpment and segments that they have just won. Can it be that they have to live with other technology enabling the existing operators to offer HDR as they are doing if it is done merely by upgrades? If this is the case then in any territory that cdma-one is currently is operation e.g. Korea then so long as one of the existing operators decides to do so he can go with cdma-2000 without having to go through a licensing procedure and then upgrade to cdma-2000 and his cost advantage will effectively put any competition based on W-CDMA out of business. Is this correct? Best regards, L
