ITU-T Q.3231 (08/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations s

13、pecialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on th

14、em with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-

15、T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used

16、 for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the

17、Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of a

18、ny party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Prope

19、rty Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, imp

20、lementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

46、s 6.3.1 Transport location management physical entity (TLM-PE) TLM-PE responds to location queries from service control functions and applications. The actual information delivered by TLM-PE may take various forms (network location, geographical coordinates, postal address, etc.) depending on the ag

47、reement with the requester and on user preferences regarding the privacy of its location. The TLM-PE may play several roles, i.e. the Home role, the Local role, or both. In its Home role the TLM-PE stores a pointer to the TLM-PE instance that is playing the Local role for the attachment. The current

48、 location information of the user/CPE in the access domain is stored and bound in the Local TLM-PE. So when the user/CPE moves in the same access domain, only the location binding Rec. ITU-T Q.3231 (08/2016) 5 information of the Local TLM-PE needs to be updated; the location binding information of t

49、he Home TLM-PE does not need to be updated. The Local TLM-PE is in the access network to which the terminal equipment is attached. The Home TLM-PE is in the network designated by the Transport User Profile Physical Entity. Where these networks differ, communication between the Local and Home TLM-PE instances takes place over the Ng reference point. Namely, the home TLM-PE may provide the SCE with user network profile information through the local TLM-PE of visit network to sup
