Q3 Why is an Accounting Authority required?
An AA is required to take care of the bills of a ship or land mobile, as it moves from one location to another.
After a Mobile Earth Station (MES) makes a call through an LES, the LES Operator (LESO) identifies the Accounting Authority Identification Code (AAIC) for that MES, and subsequently sends the charge for the call to the AA. If an MES incurs call charges with several LESOs, each LESO passes details of its charges to the AA. The AA consolidates all the charges into a single bill which it then submits to the MES customer for settlement.
An MES will only be commissioned if a valid AAIC is entered into the commissioning form.
Arrangements will be made by an AA with the relevant Point of Service Activation (PSA) to reflect their AAIC as that for their ship or land mobile. The PSA concerned will commission your ship or land mobile and inform Inmarsat London accordingly. Inmarsat London will then broadcast the updated information to all the service providers (i.e. Land Earth Stations) in the world, so that the bills for the mobile stations will be correctly dispatched and settled.
