WTSA-08 Resolution 61 3 Attachment (to Resolution 61) Suggested guidelines for regulators, administrations and operating agencies authorized by Member States for dealing with number misappropriation In the interest of global development
18、 of international telecommunications, it is desirable for regulators, administrations and operating agencies authorized by Member States to cooperate with others and to take a collaborative and reasonable approach to avoid the blocking of country codes. Cooperation and subsequent actions would have
19、to take account of the constraints of national regulatory frameworks and laws. It is recommended that the following guidelines be applied in country X (the location of the calling party), country Y (the country through which the call is routed) and country Z (the country to which the call was origin
20、ally destined) regarding number misappropriation. Country X (location of call origination) Country Y (country through which the call is routed) Country Z (country to which the call was originally destined) On receipt of a complaint, the national regulator finds the information: name of the carrier f
21、rom which the call originated, time of the call and called number, and passes this information to the national regulator in country X. When a complaint is received, the first information that is required is the name of the carrier from which the call originated, the time of the call and the called n
22、umber. Once the call details are known, the national regulator requests relevant information from the carrier from which the call originated, to determine the next carrier through which the call was routed. Once the relevant information has been found, the national regulator is to advise the nationa
23、l regulator of the next country of the call details (including the call detail record) and request the national regulator to request further information. The national regulator asks the other carriers for relevant information. This process continues until the information on where the call was misapp
24、ropriated is found. Cooperation from national regulators, as appropriate, to manage these issues. Cooperation is required from entities involved, to attempt to bring a criminal case against the perpetrators. Cooperation is encouraged between and among national regulators involved, to resolve these issues.
