Introduction to erstwhile Unified Access Services/Cellular Mobile Services

The country is divided into 22 Service Areas consisting of 19 Telecom Circle Service and 3 Metro Service Areas for providing Unified Access Services (UAS). Unified Access Services operators are free to provide, within their area of operation, services which cover collection, carriage, transmission and delivery of voice and/or non-voice messages over Licensee's network by deploying circuit and/or packet switched equipment. Further, the Licensee an also provide Voice Mail, Audiotex services, Video Conferencing, Videotex, E-Mail , Closed User Group (CUG) as Value Added Services over its network to the subscribers falling within its service area on non-discriminatory basis. The Licensee cannot provide any service except as mentioned above, which require a separate licence. However, an intimation before providing any other value added service has to be sent to the Licensor and TRAI. An Unified Access Services licensee can provide wireline as well as wireless services in a service area. Wireless services include Full Mobile, Limited Mobile and Fixed Wireless services. The licensee can also provide various Value Added Services . A restriction for authentication of subscriber terminal has been placed. In case of Limited Mobility facility based on Short Distance Charging Area Linked Numbering Scheme. However, same facility without any restriction can be availed by adopting numbering plan for Cellular Mobile Services and using Home Zone Tariff Schemes. Basic and Cellular Services Licensees are permitted to migrate to Unified Access Services Licence regime. The service providers migrating to Unified Access Services Licence will continue to provide wireless services in already allocated/contracted spectrum and no additional spectrum will be allotted under the migration process for Unified Access Services Licence. Guidelines for such migration were announced on 11.11.2003 and are available on this website. The spectrum charges are levied separately. For wireless operations in SUBSCRIBER access network, the frequencies shall be assigned by WPC wing of the Department of Telecom from the frequency bands earmarked in the applicable National Frequency Allocation Plan and in coordination with various users. Initially a cumulative maximum of upto 4.4 MHz + 4.4 MHz shall be allocated in the case of TDMA based systems @ 200 KHz per carrier or 30 KHz per carrier or a maximum of 2.5 MHz + 2.5 MHz shall be allocated in the case of CDMA based systems @ 1.25 MHz per carrier, on case by case basis subject to availability. While efforts would be made to make available larger chunks to the extent feasible, the frequencies assigned may not be contiguous and may not be the same in all cases or within the whole Service Area. For making available appropriate frequency spectrum for roll out of services under the licence, the type(s) of Systems to be deployed are to be indicated. Additional spectrum beyond the above stipulation may also be considered for allocation after ensuring optimal and efficient utilization of the already allocated spectrum taking into account all types of traffic and guidelines / criteria prescribed from time to time. However, spectrum not more than 5 + 5 MHz in respect of CDMA system or 6.2 + 6.2 MHz in respect of TDMA based system shall be allocated to any new Unified Access Services Licensee. The spectrum shall be allocated in 824-844 MHz paired with 869 - 889 MHz, 890 - 915 MHz paired with 935 - 960 MHz, 1710 1785 MHz paired with 1805 1880 MHz.
