This form of porting is known as "donor-led" and has been criticised by some industry analysts as being inefficient, though it prevents MNP scams. The recipient continues the porting process by contacting the donor with a porting code. In the case of a donor-led system, the customer wishing to port their number is required to contact the donor to obtain a Porting Authorisation Code (PAC) in the UK— or a Unique Porting Code (UPC) in India —which is then given to the recipient network. By contrast, the UK and India are the only exceptions to implement a "donor-led" system. This is known as "recipient-led" porting.
There are various flavours of call routing implementation across the globe but the International and European best practice is via the use of a central database (CDB) of ported numbers. ( April 2014) ( Learn how and when to remove this template message)A significant technical aspect of MNP is related to the routing of calls or mobile messages ( SMS, MMS) to a number once it has been ported. Unsourced material may be challenged and removed. Please help improve this article by adding citations to reliable sources. One of the very few countries not to use ACQ/CDB is the UK, where once a number has been ported, calls to that number are still routed via the donor network. A majority of the established and upcoming MNP systems across the world are based on this ACQ/CDB method of call routing. According to RFC3482, this is also known as All Call Query (ACQ) and is highly efficient and scalable. Excel for mac 2011 turn off 2 sided printingOn 17 July 2007, Ofcom released its conclusions from the review of the UK MNP and mandated reduction of porting time to 2 working days effective 1 April 2008. Prior to March 2008, it took a minimum of 5 working days to port a number in the UK, compared to 3.5 working days in Pakistan, 2 hours in United States, as quickly as 20 minutes in the Republic of Ireland, 3 minutes in Australia, and a matter of seconds in New Zealand. The UK telecoms regulator Ofcom completed its extended review of the UK MNP process on 29 November 2007, and mandated that ACQ/CDB be implemented for mobile to mobile ported calls by no later than 1 September 2009. Because of its donor dependent nature, indirect routing also means that if the donor network develops a fault or goes out of business, the customers who have ported numbers out of that network will lose incoming calls to their numbers. The reduction in barriers to switching is of particular benefit to challenger carriers against dominant incumbents. A number of such services exist, which query the operator's HLR over the SS7 signalling network in order to determine the current network of a specified mobile phone number prior to attempted routing of messaging or voice traffic.Impact of MNP on mobile carriers and customers MNP is important for the telecom markets because it removes a hurdle to switching that might keep those with much equity in the number— in particular business users —prisoner behind a high switching barrier. In a decentralised model of MNP, an FNR (flexible number register) may be used to manage a database of ported out/ported in numbers for call routing.Service providers and carriers who route messages and voice calls to MNP-enabled countries might use home location register (HLR) query services to find out the correct network of a mobile phone number. On 8 July 2010, Ofcom issued a final statement, retaining the donor-led process, mandating a two-hour PAC release time, and reducing the porting time from two to one working day. However, in early 2008 Vodafone UK appealed the Ofcom statement before the Competition Appeal Tribunal (CAT), and on 18 September 2008, CAT ruled in favor of the appeal, returning the matter back to Ofcom for reconsideration. In the network, you may be charged unexpectedly for a call to a mobile that has been ported form a different network.Number portability is available nationwide, provided the customer should have completed a period of 90 days (from the date of activation of the mobile connection) with the current operator, to be eligible for porting to another operator. Similarly, after porting to a new provider the number would be locked in for 90 days.GrameenPhone, Robi, Airtel-bd, Banglalink all operator can port own Number.The duration for the process is 7 days and the time a number is deactivated for portability is about 2 hours.Service handled by Office of the Communications Authority (OFCA).
