5、ontreal, 2000; Florianpolis, 2004; Johannesburg, 2008) The World Telecommunication Standardization Assembly (Johannesburg, 2008), recalling a) Resolution 1099, adopted by the Council at its 1996 session, concerning alternative calling procedures on international telecommunication networks, which urg

6、ed the ITU Telecommunication Standardization Sector (ITU-T) to develop, as soon as possible, the appropriate Recommendations concerning alternative calling procedures; b) Resolution 22 (Rev. Doha, 2006) of the World Telecommunication Development Conference, which resolves: i) to encourage all admini

7、strations and international telecommunication operators to enhance the effectiveness of ITUs role and to give effect to its Recommendations, particularly those of ITU-T Study Group 3, in order to promote a new and more effective basis for the accounting regime which would help limit the negative eff

8、ects of alternative calling procedures on developing countries, including least developed countries, small developing island states and countries with economies in transition; ii) to request the Telecommunication Development Sector (ITU-D) and ITU-T to collaborate so as to avoid any duplication of e

9、ffort in studying the issue of refile, in order to achieve an outcome based on the spirit of Resolution 21 (Rev. Antalya, 2006) of the Plenipotentiary Conference; iii) to request administrations and international operators which permit the use of alternative calling procedures in their country in ac

10、cordance with their national regulations to respect the decisions of other administrations and international operators whose regulations do not permit such services; c) Resolution 21 (Rev. Antalya, 2006) of the Plenipotentiary Conference concerning alternative calling procedures on telecommunication

11、 networks, which resolves: i) to encourage administrations and international telecommunication operators to implement ITU-T Recommendations in order to limit the negative effects that, in some cases, alternative calling procedures have on developing countries; ii) to request administrations and inte

12、rnational operators which permit the use of alternative calling procedures on their territory in accordance with their national regulations to pay due regard to the decisions of other administrations and international operators whose regulations do not permit such services; iii) to request competent

13、 ITU-T study groups to continue, through contributions from Member States, Sector Members and Associates, to study alternative calling procedures, such as refiling and call-back, and issues related to caller identification, taking into account the importance of such studies as they are related to ne

14、xt-generation networks (NGNs) and network degradation, recognizing a) that call-back, refiling, non-identification1and other alternative calling procedures, which may be potentially harmful, are permitted in some countries and not in others; _ 1The lack of sufficient information to allow identificat

15、ion of the origin of the call. 2 WTSA-08 Resolution 29 b) that call-back, refiling, non-identification and other alternative calling procedures, which may be potentially harmful, offer alternative calling procedures which may be attractive for users; c) that call-back, refiling, non-identification a

16、nd other alternative calling procedures, which may be potentially harmful, affect the revenue of operating agencies authorized by Member States, which may seriously hamper, in particular, the efforts of developing countries, including the least developed countries, small island developing states and

17、 countries with economies in transition, for the sound development of their telecommunication networks and services; d) that distortions in traffic patterns resulting from call-back, refiling, non-identification and other alternative calling procedures, which may be potentially harmful, may impact o

18、n traffic management and network planning; e) that some forms of call-back seriously degrade the performance and quality of the public switched telephone network (PSTN), reaffirming that it is the sovereign right of each country to regulate its telecommunications and as such it may permit, prohibit

19、or otherwise regulate call-back, refiling or matters related to caller identification in its territory, noting that in order to minimize the effect of alternative calling procedures: a) operating agencies authorized by Member States should, within their national law, make every effort to establish t

20、he level of collection charges on a cost-oriented basis, taking into account Article 6.1.1 of the International Telecommunication Regulations and Recommendation ITU-T D.5; b) administrations and operating agencies authorized by Member States should vigorously pursue the implementation of Recommendat

21、ion ITU-T D.140 and the principle of cost-oriented accounting-rates and accounting rate shares, resolves 1 that administrations and operating agencies authorized by Member States should take all reasonable measures, within the constraints of their national law, to suspend the methods and practices o

22、f call-back which seriously degrade the quality and the performance of the PSTN, such as constant calling (or bombardment or polling) and answer suppression; 2 that administrations and operating agencies authorized by Member States should take a cooperative and reasonable approach to respecting the

23、national sovereignty of others, and suggested guidelines for this collaboration are attached; 3 to continue developing appropriate Recommendations concerning alternative calling procedures and, in particular, the technical aspects of the methods and practices of call-back which seriously degrade the

24、 quality and the performance of the PSTN, such as constant calling (or bombardment or polling) and answer suppression; 4 to request Study Group 2 to study other aspects and forms of alternative calling procedures, including refiling and non-identification; 5 to request Study Group 3 to study the eco

25、nomic effects of call-back on the effort of developing countries, including the least developed countries, small island developing states and countries with economies in transition, for sound development of their local telecommunication networks and services, and to evaluate the effectiveness of the

26、 suggested guidelines for consultation on call-back, WTSA-08 Resolution 29 3 calls upon the Director of the Telecommunication Standardization Bureau to cooperate with the Director of the Telecommunication Development Bureau in order to facilitate the participation of countries with economies in tran

27、sition, developing countries, and especially least developed countries, in these studies and to take care of such studies. Attachment (to Resolution 29) Suggested guidelines for administrations and operating agencies authorized by Member States for consultation on call-back In the interest of global

28、 development of international telecommunications, it is desirable for administrations and operating agencies authorized by Member States to cooperate with others and to take a collaborative and reasonable approach. Any cooperation and any subsequent actions would have to take account of the constrai

29、nts of national laws. The following guidelines are recommended to be applied in country X (the location of the call-back user) and country Y (the location of the call-back provider) regarding call-back. When call-back traffic is destined to a country other than countries X or Y, the sovereignty and

30、the regulatory status of the destination country should be respected. Country X (location of call-back user) Country Y (location of call-back provider) A generally collaborative and reasonable approach is desirable A generally collaborative and reasonable approach is desirable Administration X, wish

31、ing to restrict or prohibit call-back, should establish a clear policy position Administration X should make known its national position Administration Y should bring this information to the attention of operating agencies authorized by Member States and call-back providers in its territory using wh

32、atever official means are available Administration X should instruct operating agencies authorized by Member States operating in its territory as to the policy position, and those operating agencies authorized by Member States should take steps to ensure that their international operating agreements

33、 comply with that position Operating agencies authorized by Member States in Y should cooperate in considering any necessary modifications to international operating agreements Administration Y and/or operating agencies authorized by Member States in Y should seek to ensure that call-back providers

34、establishing an operation in their territory are aware that: a) call-back should not be provided in a country where it is expressly prohibited, and b) the call-back configuration must be of a type which will not degrade the quality and performance of the international PSTN Administration X should ta

35、ke all reasonable steps within its jurisdiction and responsibility to stop the offering and/or usage of call-back in its territory which is: a) prohibited; and/or b) harmful to the network. Operating agencies authorized by Member States in country X will cooperate in the implementation of such steps

36、. Administration Y and operating agencies authorized by Member States in Y should take all reasonable measures to stop call-back providers in its territory offering call-back: a) in other countries where it is prohibited; and/or b) which is harmful to the networks involved. 4 WTSA-08 Resolution 29 N

37、OTE For relations between countries who regard call-back as an “international telecommunication service“ as defined in the International Telecommunication Regulations, bilateral operating agreements should be required between the operating agencies authorized by Member States concerned as to the conditions under which call-back will be operated.
