Number Portability by Roaming in Fixed Networks with HLR and VLR. Now roaming is possible only in the Wireless networks. However, as discrimination between Wired and Wireless networks is vanishing, it is possible to have roaming in wired netwroks also with Combination Switching systems which can provide connectivity to both wired and wireless phone users. There are already such COMBI-Switches manufactured and supplied by some vendors. With the advancement of Technology, it is possible to provide full number portability in Fixed Networks by way of roaming by introducing Network switching systems with HLR and embedded VLR in Fixed Networks also. |

Roaming in Fixed Network !!!
The topic "Roaming in Wired Network" may seem to be a weird idea for many until we look in evolving philosophy of telecom topography, user needs and business viability.
1. In detail analysis, it can be seen that with higher data rates, the differentiation between Fixed Network and Mobile Network will narrow down to the type of end link and terminal device. This is because, networking of enormosly large number of "small coverage area cell" sites required for High Data service delivery with M/W and Radio links is impossible without Optical Cable back bone connectivity. Therefore, the topology of the the high data service mobile network in effect becomes same as that of fixed netwrok with a wireless end link.
2. Further analysis on the services needed by the users in the mobile situation and the data rate required for delivering that service, it can be seen that the data rate of 384 to 586 Kbps, if delivered properly, is more than adequate for top good quality products such as 'real time' video for video conferencing, viedio gaming, TV news, real time movie display and Multi-media transactions over internet etc.
At this 384 to 586 Kbps data rate, the vehicle carrying the Mobile terminal can also move at its normal speed without compromisisng quality of service.
3. Higher data rates of 2 Mbps and above, are required only for quick down loading of high volume contents such as a digital movie etc. The utility of such services will be rare in a mobile situation and therefore, cannot become a major revenue earling product. Such high volume data files can be easily carried in plug and play storage devices.
Making available any time, anywhere at such 2Mbps and above high data rate is near to impossible in terms of a viable business plan. It could be realized only in limited hot spots and the Mobile device in more or less stationery situation which is identical to Wired phone which can also provide limited mobilty in a fixed network scenario.
4. What is missing here is the mobility factor in a mobile network where user can use his own terminal device at diferent places. This need of the user can be realized if the user can plug in a dual mode device to a fixed network socket or get service through a Wi Fi connectivity as the end link at the prmises. This can be achieved with a fixed network switching sytem that can identify and give the needed service to the user in ths same way it is done in the mobile switching system or in other words, where the function of the switching systems of fixed and mobile networks are identical except for the mode of line termination at the switching system end.
5. In GSM / CDMA every user is "Roaming" even if the mobile is not taken out of the home. Deployment of switches that can provide same facilities to fixed lines, can considerably ofset the cost of investment on mobile networks needing very high data handling cpability.
Switching systems known as "COMBI SWITCH" that are capable of providing service to both Mobile and fixed network users, are already available in some network.
6. It is also possible to realize full 'number protability' in fixed networks inby introducng this idea. The user need to carry his SIM and just insert it in any phone connected to such swithcing systems which will readily provide service on the spot across the world.
7. It will do good for the telecom industry to give serious thougts in this instead giving false promises of high data anywhere, everywhere, anytime, which find its place only in Hyped up Sales talks and never to be a useful product and a aviable business option.

The idea was mooted by me years back. I would like to know any development happened in this field. Four different ideas are covered here: a) Segregation of Service Provision and Network Operation. b) Different Service Providers can avail service from common network. c) End users can choose the Network Operator or Carriers according to their will for getting service. c) Wired network phones shall also have roaming facility. The ideas in detail: - Service providers will have their HLRs operated by one of the Network Operators. -End users will have option to avail service from any one or different Network Operator that provide service in the area. -Large number of Service providers can be served with few Network operators so that cost of service become less. -The fixed phones will have features of the Mobile phone equipped wth the SIM, which is activated in the HLR /AuC of the Service Provider. -In the switching system end, the physical lines are multiplexed into EI streams and get connected to the switch bye passing the TRAU. -The phone remain logged in the VLR of the switching system to which it is connected. -When the subscriber moves to another VLR area, he can use his SIM in any phone connected to a fixed phone line in that area and continue to get the service without number change etc. through that Fixed Network switch. - As the HLR is updated with the new location information, the subscriber can get incoming calls routed directly through the new VLR Switch by Optimal routing. - With Roaming / Number portability understanding between various Service Providers, Subcribers can have the service anywhere in the world. The advantages are:- 1. With FTH and PON in wired network, it is possible to have very high speed connectivity for multi-media usage over the phone lines compared to that through Mobile phones. 2. As the data speed increases for getting serviced through WCDMA / UMTS, the actual portion of Wirelss part becomes less and less. In practical terms, the portion of the wired network will become more and predominent in high data rate communication networks, the wireless portion limited to the end link. This is because the cell area become smaller and smaller and it is not possible to have radio connectivity to large number of small cells thorugh M/W links etc. 3. The fixed network phones can be networked for home or office use for Voice, Data, FAX, Video, Multimedia and Internet related services. 4. Most of the fixed network phone derive power from the line and therefore, do not require battery or external power for it's normal use. The phones can comprise of a Powered base station with wireless handsets that could be carried around in the vicinity. 5. There is no restriction on the the size of the phone, allowing to have more built in fetures. 6. These phones connections with SIMs could be part of Data line PABX which can provide numerous features and facilities. 7. There need not be any change in sevices, billing etc. Abraham paul

Well, its a nice idea Mr.Paul, Having a sim card and using it in any phone connected to a fixed phone line. But what about the phone, we all have a fixed landline phone and this feature is not available yet right :).
This feature shall require huge R&D expenditure on the phone with sim, which might take long.
Also the acceptance of such phone by the masses will not be an easy task.

Well Mr. paul, Much of the ideas you have written are already possible in IMS concept and technologically choice of service operator is not a problem even now. Devinder |
