12、-en. ii Rec. ITU-T Q.3228 (08/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ o
13、f ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topi
14、cs for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-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 prep
15、ared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation ma
16、y contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the 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 e
17、xpress requirements. The use of such words does not suggest that compliance with the Recommendation is required of any 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 Pr
18、operty Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property 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
19、of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers 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/. ITU 2016

ITU-T Q.3228 (08/2016) 3 6 M1 interface 6.1 Overview This information flow is used to distribute several types of information from the TLM-PE t
38、o the MLM-PE(P) defined in the stage 2 specification ITU-T Y.2014 and ITU-T Y.2018. The M1 interface allows the exchange of information about mobility service parameters. Figure 6-1 Reference points between the NACF and the MMCF ITU-T Y.2018 6.2 Physical entities 6.2.1 Transport location management
39、physical entity (TLM-PE) The TLM-PE is assumed to be able to contact the NAC-PE via an internal reference point to obtain the persistent and temporary IP addresses. In the host-based mobility case, the information passed from the TLM-PE includes the keying material derived from the UE authentication
40、 procedure to support the security association between the MLM-PE(P) and the UE. Also, it may include mobility service user ID, persistent IP address of the user, and binding between mobile user ID and persistent IP address. In the case of network-based mobility, the transferred information includes
41、 the identifier or persistent address, the address of the MLM-PE(C) instance for this connection, and may include the lower tunnel end point address and other parameters relating to mobility service. 6.2.2 Mobility location management physical entity (MLM-PE) When the TLM-PE indicates network-based
42、mobility service to the MLM-PE(P), this indication will trigger the mobile location registration procedure, and indirectly trigger handover. 7 Signalling requirements Reference point M1 allows the TLM-PE to interact with the MLM-PE(P) for pushing mobility service parameters, such as keying material
43、and anchor address. The TLM-PE holds keying material, anchor address, etc. in the mobility service parameters information shown in Table 7-1 and pushes keying material to MLM-PE(P). The M1 reference point should allow information exchange as follows: information about mobility service parameters is
44、pushed by the TLM-PE to MLM-PE(P). 4 Rec. ITU-T Q.3228 (08/2016) Table 7-1 Information about mobility service parameters in TLM-PE Parameter Description Received from Address of MLM-PE(C) The address of the instance of the MLM-PE containing the mobile address binding information. NAC-PE Address of M
45、LM-PE(P) The address of the MLM-PE instance which sends the location registration. Keying Material The material used for the security association between the UE and MMCE. TAA-PE Mobility Protocol Type The type of mobility protocol, such as host-based or network-based mobility. Anchor point address T
46、he upper tunnel end point address, from the point of view of the UE. Tunnel end point address The tunnelling end point address for the network node which works as UEs proxy (lower tunnel end point). The following information flows shall be used on the M1 interface: Indication of host-based mobility;
47、 Indication of network-based mobility. Figure 7-1 shows the information flows between the TLM-PE and the MLM-PE(P) through the M1 interface. Figure 7-1 Information flow 7.1 Indication of host-based mobility In the host-based mobility case, the transferred information includes the keying material der
48、ived from the UE authentication procedure, in support of the security association required between the MLM-PE(P) and the UE. The information passed from the TLM-PE to the MLM-PE(P) may also include: mobility service user ID; persistent IP address of the user; binding between mobile user ID and persi
49、stent IP address. The TAA-PE obtains these mobility service parameters from an AAA entity in the mobile subscribers home network. How the TAA-PE determines that mobility service is to be provided and that mobility service parameters are required is out of the scope of this Recommendation. The contents of the “indication of host-based mobility“ primitive described in ITU-T Y.2018 are shown in Table 7-2. Rec. ITU-T Q.3228 (08/2016) 5 Table 7-2 Indication of host-based mobility
