The Dipping charge shall be payable by those telecom service providers who utilize the dipping services (query response services) from the MNP Service Provider.
The Porting Charge is payable by the subscriber to the recipient carrier for porting his mobile number.
On 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.
According to RFC3482, this is also known as All Call Query (ACQ) and is highly efficient and scalable.
A majority of the established and upcoming MNP systems across the world are based on this ACQ/CDB method of call routing.
Mobile number portability is implemented in different ways across the globe.
The International and European standard is for a customer wishing to port his/her number to contact the new network (recipient), which then sends the number portability request (NPR) to the current network (donor). The UK and India are the only exceptions to implement the donor-led system.
