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.
